Yuzui Diversion Dike

I've heard people say that you can go to Qingcheng Mountain to seek the Tao and worship the water at Dujiangyan, so I went there to worship the water. I discovered a problem, that is, the water conservancy project at Dujiangyan is really amazing, but if you don't have some basic theoretical knowledge, you may really not understand it... Fortunately, I made up for it before I went there and showed off in front of my friends. Hahahaha.

Yuzui is another important part of Dujiangyan. It is a water diversion dam built in the middle of the river, which separates the turbulent Minjiang River into the outer river and the inner river. The outer river is used for flood discharge, and the inner river is used for irrigation.

Dujiangyan is a great water conservancy project built in ancient times that still benefits mankind today. It is known as the "ancestor of the world's water conservancy culture." Yuzui diversion dike is one of the Dujiangyan system projects.

The Yuzui diversion gate embankment is an important feature of the Dujiangyan Irrigation System and has been silently functioning for thousands of years.

The entire dike separates the inner river from the outer river, and is named Yuzui Dike because it looks like a fish mouth. If you want to see the beauty of Yuzui, it is recommended to take a sightseeing bus from Beiting Station directly to Yuzui Station. The one-way fare is 10 yuan, and the round trip fare is 15 yuan. However, it is recommended to take a one-way tour, because after seeing the beauty of Yuzui, you can directly cross the inner river from Anlan Bridge to continue visiting the cultural attractions along the coast without going back.

Yuzui Diversion Dike, also known as "Yuzui", is a water diversion project of Dujiangyan. It is named because of its shape like a fish mouth. It is located in the middle of Minjiang River and includes a whole set of facilities such as Baizhang Dike, Macha Dike and Jingang Dike. Its main function is to divide the turbulent Minjiang River into two rivers, the outer river and the inner river. The western one is called the outer river, commonly known as the "Jinma River", which is the main stream of Minjiang River and is mainly used for flood discharge; the eastern one along the foot of the mountain is called the inner river, which is an artificial water diversion channel and is mainly used for irrigation.

The Dujiangyan Scenic Area is Tick's way to the "Fish Mouth", which is almost the end of the entire scenic area.

All the way to Yuzui, the scenery of Qingcheng Mountain is on the left, which is indescribably beautiful.

This is a part of Dujiangyan. It is not very scenic on its own, but it is amazing as part of a water conservancy project.

In the middle of the river, walk to the front. This is also where the most people gather - Yuzui. Yuzui is the core of Dujiangyan, dividing the Minjiang River into two parts and draining a lot of silt.

The Dujiangyan Irrigation System starts from the Yuzui diversion dike, which is the first step in diverting the Minjiang River.

Dujiangyan Scenic Area is located on the Minjiang River in the west of Chengdu Plain, Sichuan Province, and is located in the west of Dujiangyan City, Sichuan Province.

Dujiangyan is not only a world-famous ancient Chinese water conservancy project, but also a famous scenic spot. There are beautiful scenery and many cultural relics near Dujiangyan, including Fulong Temple, Erwang Temple, Anlan Cable Bridge, Yulei Pass, Lidui Park, Yulei Mountain Park, Yunu Peak, Lingyan Temple, Puzhao Temple, Cuiyue Lake, Dujiangyan Water Conservancy Project, etc.

After Baopingkou and Feishayan, you will see the first Fish Mouth that diverts the river water. The Fish Mouth was built with sandstone in ancient times, but now it is directly changed to concrete. According to the introduction on site, the structure of Dujiangyan can automatically release most of the water into the basin during the dry season, and automatically limit the flow during the flood season.

The wisdom of the ancients is shocking. Such a magnificent water conservancy project has been built for more than 2,000 years.

Fish Mouth is the most important attraction in Dujiangyan Scenic Area. Here the river water is divided into two channels. This technology was very advanced and magical more than 2,000 years ago.

It was the dry season when we went there so there was no water and no scenery to see.

The Yuzui Diversion Dike is located at the northernmost end of the scenic area. It is a key facility that divides the rolling Minjiang River into the outer river and the inner river, and is the foundation of the Dujiangyan water conservancy project. From here, looking north to the upper reaches of the Minjiang River, the mountains are looming in the mist. The Minjiang River flows to Yuzui and is diverted by Yuzui. The left side is the outer river; the river water on the right flows to the artificially excavated river channel, which is called the inner river. The inner river is the main source of irrigation for the Chengdu Plain, and water volume control is crucial. Dujiangyan represents not only the credit of the earliest designers and builders Li Bing and his son, but also the wisdom and sweat of the people of all generations. In 1974, the country built a permanent modern sluice gate that can achieve more convenient and precise control of water flow, replacing the ancient 杩槎. Looking from Yuzui to the inner river, the river is the Anlan cable bridge, and the building on the left mountain is the Qinyan Tower, which is an excellent place to view the panoramic view of Dujiangyan. The traditional water interception equipment 杩槎 is displayed at Yuzui. A single cha is made up of three pieces of wood tied together with a platform below. Pebbles wrapped in bamboo cages are placed on the platform and put into the water to intercept the flow. Multiple chas arranged in an array can block larger water flows. Contemporary engineering technology has greatly enhanced the capacity and strength of Dujiangyan. In the 2008 Wenchuan earthquake, although the surrounding ancillary facilities were severely damaged, the main part of Dujiangyan withstood the test and was slightly damaged but not seriously.

One of the attractions of Dujiangyan, the first diversion point, has been added with many modern things after years of construction, but it has brought many things to Chengdu.

The fish mouth plays a role of diversion, and it is quite impressive when the water is high in summer.

A classic attraction in Dujiangyan, a place you definitely cannot miss.

The design of the fish mouth is truly amazing. Foreign experts did not begin to study fluid dynamics until 2000, but Li Bing had figured it out more than 2,000 years ago and used this principle to benefit the people and creatures of all generations.

The function of the "Fish Mouth" is to use the height difference of underwater engineering to divide the river water into two parts, with the outer river being used for flood discharge and the inner river being used for irrigation.

One of the places where Li Bing managed the Dujiangyan Irrigation System, shaped like a fish mouth

This fully reflects the wisdom of the ancients, it’s so great!

The wisdom of the ancient working people is reflected! So cool!

The section from Feishayan via Baizhangdi to Yuzui is not close and there are not many attractions along the way, so you can choose to take a sightseeing bus.

The fish mouth serves to divert water, while the subsequent flying sand weir serves to discharge floodwater and wash away sand.

Aerial photography is more spectacular, and it should be even more magnificent during the flood season.

The place called Yuzui, which diverts the Minjiang River, has a riverbed that is half wide and half narrow. Li Bing is amazing.

The significance of the fish mouth is to play the role of water diversion and sedimentation of the bifurcated river. For example, in the winter and spring dry seasons, the water level of the Minjiang River is low, and the main stream of the river mostly flows close to the concave bank of the river valley. The diversion dike will drain about 60% of the river water into the inner river and 40% of the river water into the outer river, ensuring the water consumption of the irrigation area, referred to as "46 water division"; in the summer and autumn flood seasons, the water level of the Minjiang River rises relatively, the main stream of the river becomes relatively straight, and most of the river water flows to the convex bank, so the diversion dike will drain 60% of the river water into the outer river and 40% of the river water into the inner river. It fully demonstrates the wisdom of the ancients! Worth a visit!

When the water volume is small, it flows into the inner river on the right. When the water volume is large, the outer river on the left can be used for flood diversion and it can also drain sand with the help of the horse fork. This is the first project of Dujiangyan.

Yuzui Diversion Dike, also known as "Yuzui", is a water diversion project of Dujiangyan. It is named because of its shape like a fish mouth. It is located in the middle of Minjiang River and includes a set of coordinated facilities such as Baizhang Dike, Macha Dike and Jingang Dike. Its main function is to divide the turbulent Minjiang River into two rivers, the outer river and the inner river. The western one is called the outer river, commonly known as the "Jinma River", which is the main stream of Minjiang River and is mainly used for flood discharge; the eastern one along the foot of the mountain is called the inner river, which is an artificial water diversion channel and is mainly used for irrigation.

2018.1.20 The whole family visited Dujiangyan and came to the world-famous Fish Mouth. Although the Fish Mouth we see now was built in recent years and the original Fish Mouth is already 200 meters away, we can still feel the magnificence of this world heritage site.

When the emerald green river water reaches here, it naturally filters the sand and enters the irrigation area for the first time!

The essence of the Dujiangyan Irrigation Project! Worth a visit! !

The Yuzui building is located in the center of the Minjiang River where it flows out of the mountain pass and forms a bend. It mainly plays a role in flood diversion.

It is said that Li Bing used the method of building a weir in the middle of the river, and built a stone ridge with stones in the Minjiang Gorge, which was called Dujiang Yuzui, also known as the water-dividing Yuzui. Yuzui is a water-dividing construction project that divides the Minjiang River into two. The eastern one is called Neijiang, which supplies water for irrigation canals; the western one is called Waijiang, which is the main stream of the Minjiang River. Lidui (same as pile) was built on the south bank of the Minjiang River. Lidui is a pile of stones separated after the rock was excavated, sandwiched between the inner and outer rivers. The east side of Lidui is the water outlet of Neijiang, called Baopingkou, which has the function of regulating the flow of water. In summer, the water level of the Minjiang River rises, and Dujiang Yuzui is submerged, and Lidui becomes the second water-dividing point. Neijiang enters the irrigation system densely distributed on the western Sichuan plain from Baopingkou, and water is diverted for infiltration during droughts.

Li Bing, who lived more than 200 years before Christ, had such wisdom. He eliminated floods and irrigated farmland, which benefited the people of Chengdu Plain for more than 2,000 years. Apart from him, there are probably few people who can be called "benefiting future generations", right?

The Fish Mouth, the Feishayan and the Baopingkou are really useful. You will only understand their mysteries after listening to the storytelling explanation of the tour guide. In short, the Dujiangyan Irrigation Project consists of three major parts: the Fish Mouth Diversion Dike, the Feishayan Spillway and the Baopingkou Inlet. It scientifically solves the problems of automatic diversion of river water, automatic sand discharge and control of water inlet flow, eliminates floods and makes the western Sichuan plain a "land of abundance" where "water and drought are controlled by people".

One of the important scenic spots in Dujiangyan Scenic Area. The scenery is just average, but after listening to the explanation, I can feel more favorable towards it.

The diversion dam is very spectacular. It has protected the Chengdu Plain for thousands of years, with people controlling floods and droughts and never experiencing famine.

Although it was the dry season, I could still feel the passionate water flow, and I was amazed at the wisdom, perseverance, and strong heart of the ancients! ! They took advantage of the right time, right place, and right people to build such a project that benefits both mankind and nature! !

It is said that the water is divided according to certain physical principles, but I don’t understand it.

As a representative of ancient Chinese water conservancy projects, we can appreciate the wisdom of the ancients. Moreover, this water conservancy project is environmentally friendly and is a combination of human wisdom and nature.

2006年9月在一次來到都江堰

At the viewing point, you can clearly see the diversion of the fish mouth

I have learned about Dujiangyan in textbooks since I was a child, but I was still shocked when I saw the real scene. The water of Minjiang River is very cool.

Located in the Dujiangyan Scenic Area, it is one of the scenic spots and is worth a visit.

The wisdom of the ancients is endless. I strongly recommend following a tour guide to listen to

I went there in early April, and the water level was not high. The left side was dry. You can clearly see how the water was diverted when it rose. I admire the wisdom of the ancients and feel proud.

The fish mouth guides water into the inner river and filters out large rocks. In winter, you can see sand and gravel deposited on the bottom of the dried-up outer river.

Don’t take the electric car to Yuzui. It’s a waste of time to queue up. Just stroll there and you’ll get there in a short while!

As the core project of Dujiangyan, it is recommended to listen to the explanation, so that you can have a deeper understanding of the role of Yuzui. You can't tell what it is just by looking at it.

It is named after its shape resembling a fish mouth. Located at the top of the canal head, it cleverly divides the water of the Minjiang River into two rivers, the inner and outer rivers, facing the waves of the Minjiang River. The outer river is a natural river channel, which discharges a large amount of flood water in the rainy season and finally flows to Leshan, where it merges with the Qingyi River and Dadu River at the foot of the Buddha. The inner river is a river channel dug by Li Bing and others, which transports river water to the Chengdu Plain for irrigation. The fish mouth is built on the natural bend of the Minjiang River outlet. Using the principle of bend circulation, it can automatically adjust the proportion of water inflow between the inner and outer rivers during the flood season and the dry season. The riverbed of the inner river is low and located on the concave bank, while the riverbed of the outer river is high and located on the convex bank. In the flood season, the river water is restricted by the bend, and the mainstream flows to the outer river, with 60% of the water inflow and 40% of the water inflow to the inner river. In the dry season, the water volume of the Minjiang River is small and the flow rate is slow, and the water flows to the lower place, so the mainstream of the river water enters the inner river from the concave bank, with 60% of the water inflow and 40% of the water inflow to the outer river. Ensure water for arable land use in the irrigation area. This is the summary of the "4:6 water division, leveling floods and droughts" in the Three-Character Classic of Water Control. Another important function of the fish mouth is to effectively solve the problem of sediment discharge. Sand and gravel are deposited at the bottom of the river. When the water flows through the bend, the centrifugal force throws 80% of the sand and gravel into the outer river, and only 20% of the sand and gravel enter the inner river. This is the magical "4:6 water division" and "2:8 sediment discharge" of Dujiangyan.

Yuzui can be said to be the essence of the entire Dujiangyan. The reason for coming to Dujiangyan is to see this great water conservancy project. However, if you only see it yourself, you may be a little confused, so I rented an electronic guide when I visited Dujiangyan. Combined with the explanation, I can better understand the greatness of this water conservancy project. However, there are many tour groups here, and lucky friends can also take advantage of the explanation. However, because there are many tour groups, the explanations are one after another, a little confusing. . It is possible that you can't hear clearly.

After crossing the Anlan Bridge, turn right and walk about 200 meters to the Yuzui. The Yuzui is located in the center of the Minjiang River where it flows in a bend after rushing out of the mountain pass. It mainly serves as a flood diversion. I remember that the original Yuzui was made of stones, but now it has been reinforced with cement.

Yuzui Water Diversion Dam, also known as "Yuzui", is a water diversion project of Dujiangyan. Yuzui Water Diversion Dam is located at the deepest part of Dujiangyan. It is the most spectacular and worth seeing place in Dujiangyan Water Conservancy Project and can be regarded as the essence of Dujiangyan. I also took a video.

Dujiangyan is composed of three parts: Yuzui, Feisha and Baopingkou. Yuzui is a diversion dam built in the middle of the river, which divides the turbulent Minjiang River into the outer river and the inner river. The outer river is used for flood discharge, while the inner river is used for irrigation.

The most famous attraction of Dujiangyan Irrigation Project is also the top attraction. It is a water diversion structure shaped like a fish mouth, which is commonly used in ancient damless water intake hub projects.

Fish Mouth

Fish mouth (11 photos)

Fishmouths are built at the water-facing end of the river channel island or beach ridge, and their shape is determined by the terrain. The rear part is often connected to the diversion dike, which plays the role of diverting water into the canal. The location of the fishmouth and the height of the diversion dike can roughly determine the amount of water diverted. In ancient Sichuan Dujiangyan, fishmouths were used to divide and distribute water from the head of the canal to the main, branch, and sluice channels, and were the main engineering facilities.

The fish mouth is a diversion dike in terms of function. It is also very interesting, just like a long fish mouth reaching into the river.

It is one of the three major components of the Dujiangyan Water Conservancy Project. It is very shocking!

Dujiangyan is indeed a great water supply and drainage project in ancient times, which has benefited the people of Shu, and the Yuzui diversion dike has played an important role in the Dujiangyan project.

Dujiangyan is composed of three parts: Yuzui, Feisha and Baopingkou. Yuzui is a diversion dam built in the middle of the river, which divides the turbulent Minjiang River into the outer river and the inner river. The outer river is used for flood discharge, while the inner river is used for irrigation.

The design concept of the ancients is very shocking. Coming to Dujiangyan is just to broaden your horizons.

Watch the waves in the river and the water at Yuzui. Experience the passion of swimming in the middle of the river.

In the 2008 Wenchuan earthquake, the Dujiangyan ancient monuments suffered heavy losses, cracks appeared in the Yuzui water diversion embankment, the Erwang Temple, which is more than 2,000 years old, was damaged, and the Qinyan Tower also suffered heavy losses. Now there are no obvious cracks in Yuzui, and the Erwang Temple and Qinyan Tower are still as perfect as before. Just thinking of everything that has happened, I feel very sorry.

What a magical project! It has been more than 2,000 years. Yuzui is a diversion dam built in the middle of the Minjiang River. It looks like a big fish lying in the river. It divides the Minjiang River into the inner river and the outer river. The inner river is used for irrigation, and the outer river is used for flood discharge.

Yuzui is the most worthwhile place to visit in the entire scenic area. Minjiang River is divided into two rivers, inner and outer rivers, at Yuzui. Yuzui can be said to be the first checkpoint of the Dujiangyan Irrigation Project. When you come here to see it, you will be deeply impressed by the wisdom of the ancients.

In hydraulics, it is called a "diversion dam". Even today, the Dujiangyan Irrigation System is still mentioned in hydraulics classes. The ancient Chinese had great wisdom. You must see it. It is very impressive.

To be honest, I didn't really look at it because there were too many people and I was very tired from walking. I just took a photo to prove that I had been there.

"Yuzui" is the water diversion project of Dujiangyan, named for its shape like a fish mouth. It rises above the center of the Minjiang River and divides the Minjiang River into two rivers, the inner and outer rivers. The western one is called the outer river, commonly known as the "Jinma River", which is the main stream of the Minjiang River and is mainly used for flood discharge; the eastern one along the foot of the mountain is called the inner river, which is an artificial water diversion channel and is mainly used for irrigation.

Walking across the Husband and Wife Bridge and seeing the Fish Mouth Diversion Dike, the feeling will be even more profound

The scenery is beautiful, it is worth a visit, the water looks beautiful

Standing on the fish mouth, you can see the water diversion of the Minjiang River, which is the best place for the scenery of the Dujiangyan Irrigation Project.

Looking at Dujiangyan from a distance, the beautiful full picture makes it easier to grasp the greatness and subtlety of Taoism from a macro perspective...
