Alan Rope Bridge

Anlan cable bridge is located in Dujiangyan City, Sichuan Province, also known as "Anlan bridge", "husband wife bridge" and "He Gong He Mu bridge". With a total length of more than 240 meters, it flies to the north and south of Minjiang River and crosses Dujiangyan water conservancy project. It is an important commercial road between Western Sichuan and ABA in ancient times and a link between Tibetan, Han and Qiang people.

brief introduction

Anlan cable bridge, also known as Zhupu bridge, is located on the Minjiang River, about 2km northwest of Dujiangyan City, Sichuan Province. It was rebuilt in 1803. When he Xiande, a native of the city, advocated the construction of cable-stayed bridges, he used wooden boards as the bridge deck and set up railings beside it. The name of the bridge was changed to Anlan bridge. When the bridge was built, his wife Yang made a lot of efforts, which was also called "husband wife bridge" by the people. Originally 320 meters long, now 280 meters long, with wooden rafts as slabs and stone piers as columns to support the bridge body, and with cables twisted by bamboo to cross the river. In 1962, the cable bridge was repaired, and 10 bamboo bottom ropes were replaced by 6 steel ropes, and the bamboo rope on the rail was replaced by lead wire rope, which was wrapped with bamboo cables. In 1964, the Minjiang River flood broke out and the whole bridge was destroyed. During the reconstruction, only the wooden bridge piles were changed into reinforced concrete bridge piles, and the rest remained the same. Later, due to the construction of Waijiang sluice, the cable bridge was moved down 100 meters. During the reconstruction, the bungalow type bridgehead was changed into a large roof double-layer bridgehead, the single-layer diamond pavilion was changed into a hexagonal pavilion for pedestrians to rest, and the shaheihe pavilion was added, with a length of 261 meters. Anlan cable bridge is a model of cable bridge construction in the world and a national key cultural relic protection unit.

structure

Anlan cable bridge was built before the Song Dynasty and was destroyed in the war in the late Ming Dynasty. The cable bridge is supported by stone piers with wooden rafts. It flies across the river with bamboo cables as thick as bowls. It is covered with wooden planks as the bridge deck and bamboo cables as columns on both sides. The total length is about 500 meters. At present, the Anlan cable-stayed bridge has been moved down more than 100 meters from the original site. The bamboo has been changed into steel, and the wooden pile pier supporting the cable has been changed into concrete pile. Located on the head fish mouth of Dujiangyan, it is known as the five major bridges in ancient China and the most characteristic landscape of Dujiangyan.

history

Anlan bridge in front of Erwang temple is one of the five famous ancient bridges in China. It is a famous ancient cable bridge at home and abroad, crossing the water diversion between Neijiang River and Waijiang river. The earliest name is rope bridge or bamboo Teng bridge, which is related to its material. In the Song Dynasty, it was renamed "pingshiqiao". At the end of Ming Dynasty, it was destroyed by war. In 1803, Mr. and Mrs. he Xiande proposed to build a bamboo cable bridge with wooden boards and railings, so that pedestrians on both sides of the Strait could cross the raging waves safely, so it was renamed "Anlan bridge"; in memory of Mr. and Mrs. he, it was also called "husband and wife bridge". Because of the lack of railings, one man fell into the water and was killed by officials, In order to avenge her husband's injustice, the wife tried her best to repair the railings. With a total length of about 500 meters, Waijiang sluice was built at Yuzui, the bridge was moved down more than 100 meters, the bamboo cable was changed into steel cable, the wooden pile pier supporting the cable was changed into reinforced concrete pile, and the bridge body was also reduced to 240 meters. From a distance, it looks like a rainbow hanging in the air and a fisherman drying a net. The form is very unique. Walking on the bridge, you can see the Minjiang River roaring through the mountains in the West and the irrigation canals in the East. You can see the general picture and function of Dujiangyan project at a glance. However, according to the records of Huayang state, Shu Zhi, Li Bing was "able to be Zuo". "There is a bridge in the Fujiang River" in shuijingzhu Jiangshui proves that at least the construction of Anlan bridge will not be later than the construction of Dujiangyan. "Zuo" means bamboo cable, which is the main building material of ancient cable bridges in Western Sichuan, so Anlan cable bridge is also known as bamboo bridge, rope bridge, bamboo bridge, etc.

legend

In the early years of the Qing Dynasty, there was a teacher named he, who was a well-known local meddler. Once, he and his wife, Mrs. he, went on a sightseeing trip to the Minjiang River and saw the official boats ferrying people. They also wanted to go to the other side of the river. They went to ask about it, mom! One person took a boat for 10 Liang, and the couple crossed the river for 30 Liang. The behavior of these dog officials made the couple happy and came back. Back at home, Mr. He stayed up all night thinking about how to build a bridge on both sides of the Strait and cut off his financial career. One day, two days, three days, Mr. He did not eat or drink. After three days of thinking, Mr. He was at a loss. On the third night, Mr. He saw Mrs. he was embroidering. He saw the cloth, which was on the top of the frame. He thought to himself: why can't I build a cable bridge in the air? After a period of hard work and struggle, I finally built a cable bridge Bridge, those dog officials remember Mr. He's past and want to revenge him. There are no handrails on both sides of the bridge. Coupled with instability, it's easy to fall down. Unfortunately, a drunkard drowned when he was drunk and crossed the river. Dog officials seize the opportunity to arrest Mr. He and put him to death. Mrs. he is so sad that when she wants to throw into the river, she can think of her husband If she died, she would be sorry for her husband's death, so she decided to redress her husband's injustice. One day, when she was walking along the street, she saw a juggler holding two wooden sticks in both hands and flying into the air. Suddenly, she thought of installing handrails on the bridge. It would be safer for people to walk on the bridge. After two days, she installed handrails. From then on, people called Anlan bridge "He Gong He Mu" bridge.

Since then, no one has seen Mrs. he. A fisherman said that he saw the figure of He Gong and he mu in the river. He Mu has fulfilled her husband's wish to accompany her husband. They share the happiness of family in the river, live together with the sun and the moon, and live together with heaven and earth!

Hard overhaul

Wang lunyong, the leader of the engineering team of Minjiang Afforestation Bureau, is an "expert" in the maintenance of cable bridges. He began to participate in the maintenance project of Anlan cable bridge 25 years ago. After five years of Cable Bridge overhaul, there are as many as five times. On March 17, 2008, the maintenance entered the stage of laying the bridge slab. Two workers suspended in the air, trodden on the steel cable and smeared butter, while the other workers carried 20 kg of bridge slab. After four hours of construction, the bridge slab was basically laid. Zhang Gang, the engineering company of Minjiang Afforestation Bureau, who is in charge of the project, told reporters that 31 maintenance workers have participated in the maintenance of Anlan cable bridge for many times and have rich experience. "In order to maintain the original appearance of the cable bridge, we basically adopt the manual maintenance method of" repairing the old as before. " The maintenance started on February 28, 2008 is a major overhaul of Anlan cable bridge once every five years. In the initial stage of construction, the advanced ultrasonic technology is used to detect the axle plate of the bridgehead and the interior of its underground components; the steel rope, bottom rope, side rope, rail clip ear, bridge slab and hemp rope of the inner and outer river cable bridge are replaced.
