Dujiangyan is a great ancient water conservancy project in the west of Dujiangyan City, Sichuan Province. It is called the brilliant pearl of ancient water conservancy construction. At the same time, this area has beautiful scenery, many places of interest and historic sites, and is an ideal tourist destination. Dujiangyan is located where the Minjiang River flows from the mountains into the Chengdu Plain. Before the completion of this project, as soon as the water from the Minjiang River came out of the mountain pass, the velocity of flow decreased drastically, it was easy to silt and it was determined, and it often flooded. In the Warring States period of about 2200 years ago, Li Bing and his son, the prince of Shu Kingdom of Qin Kingdom, learned from their predecessors experience in water control and led the local people to build water conservancy projects.
This project includes three main components: fish mouth, flying sand weir and treasure bottle mouth. Yuzui is a water diversion dam built in the center of the river, which divides the raging Yongjiang River into the outer river and the inner river. The outer river discharges floods and the inner river diverts water for irrigation. The flying sand weir plays the role of flood relief, sand drainage and water regulation. The treasure bottle mouth controls the flow of incoming water. Because the shape of the mouth is like a bottleneck, it is called a treasure bottle mouth. Water from the Neijiang River flows into the irrigated farmland in the western Sichuan Plain through the mouth of the aquarium. The part of the hill cut off from Yulei Mountain is called Li Dui.
After the completion of the Badu River Weir, the plains of Chengdu were covered by thousands of miles, known as land and sea, the floods and droughts are from people, I dont know how to be hungry, and there is no barren year, which is called Tianfu. Sichuan s economy and culture have developed a lot, and the people have benefited a lot. This project is still working today.
Badujiangyan receives many foreign tourists every year, some of them are water experts. After some water experts carefully watched the design of the entire project, they all marveled at its high scientific level. For example, the design of the flying sand weir makes good use of the theory of swirling flow. This weir can usually be diverted and irrigated. In floods, it can be drained into the outer river. It also has the function of discharging sand and stones, and sometimes large stones can be rolled away from the weir . At that time, there was no cement. Such a large-scale project was to obtain materials in situ and use bamboo cages to install pebbles as weirs. The cost was relatively low and the effect was significant.
There are many places of interest in Badujiangyan. There is a Fulong Temple on the Lidui, the temple is triple, stands tall, and rises along the mountain. The front hall displays Li Bingshi carved from the river bed when the Waijiang Control Gate was built in 1974. It is 2.9 meters high and weighs 4.5 tons. The stone statue was built in the early years of the Emperor Ling of the Eastern Han Dynasty. It has been over 1800 years ago. It is the earliest existing round stone statue in our country and is very precious. The rear hall displays electric models of the Dujiangyan Irrigation District. On the left side of Fulongguan is the mouth of the treasure jar. The river is surging and imposing. At the highest point after the observation, there is a Guanlan Pavilion, with two floors and anise, overlooking the railing, you can see Yuzui, cable bridge and Minjiang rapids, Xiling Xuefeng.
There is the Second King Temple at the foot of Yulei Mountain. It was built by the ancient people to commemorate Li Bing s father and son s achievements in water management. It was first built in the Southern and Northern Dynasties and was named Chongde Temple. After the Song Dynasty, Li Bing and his son were named kings and renamed the Second King Temple. The existing building was rebuilt in the Qing Dynasty. The temples take advantage of the mountains, layer by layer, magnificent and beautiful, surrounded by ancient trees, and the environment is beautiful. There are statues of Li Bing and Erlang in the hall and apse. Li Bing s tactics for water management are carved between the stone walls in the temple: Deeply dig out the stalls, make the weir low and Enclosing the corner of the bay, every time Zhengzheng draws his heart and so on.
The Anlan Bridge on the Minjiang River in front of the Erhuang Temple is a cable bridge across the watershed between the Neijiang River and the Waijiang River. It was built before the Song Dynasty and was destroyed by war in the late Ming Dynasty. It was rebuilt in the eighth year of Qing Dynasty (1803). The cable bridge is supported by wooden pier piers, and a bamboo cable as thick as a bowl is used to fly across the river surface. The upper deck is covered with wooden boards, and bamboo cables are used as fences on both sides. The current bridge, due to the establishment of the Waijiang sluice at the fish mouth, moved the bridge down more than 100 meters, changed the bamboo cable to a steel cable, and the wooden pier piers by supporting cables were replaced with reinforced concrete piles, and the bridge body was also reduced to 240 meters. From a distance, it looks like a flying rainbow hanging in the air, and it looks like a fisherman s drying net. Strolling on the bridge , you can s ee the Yongjiang River roaring across the mountains in the west, the irrigation canals in the east, and the profile and function of the Dujiangyan Project.
Transportation: Chengdu Railway Station Square and Ximen Station have special tourist buses to Dujiangyan and Qingcheng Mountain every day. The buses depart every 10 minutes, which is very convenient.
