Luanhe Big Iron Bridge Review

This attraction was edited by me, haha great. The builder of the Datie Bridge in the Luohe River is Zhan Tianyou, who founded Shanhaiguan Railway Academy (now Southwest Jiaotong University). As alumnus of Southwest Jiaotong University, I drove to the road south of the Iron Bridge, and from a distance, a train was passing by the railway bridge at a speed, so close to history and modernity that a hundred years ago seemed within reach. In 1891, with the support of Li Hongzhang, the governor of Zhili, Jinda, the British man was tasked with the railway project from Guye to Shanhaiguan. The most important and difficult project of this railway was the construction of the Great Iron Bridge of the Luohe River. At the beginning, the project was successively contracted by British, Japanese and German engineers, but due to the rapid siltation of the river, the river was too thick, and all failed. At that time, Chinese railway engineer Zhan Tianyou was ordered to build the railway bridge. After taking over the construction task of the Datie Bridge of the Luohe River, Zhan Tianyou first studied various construction methods used by foreign engineers, and made a thorough investigation of the river bed geology. He decided to re-site the bridge and rebuilt the pier on the rock bed at the foot of the West Bank Hengshan Mountain and Wushan Mountain on the East Bank. Using "air caisson method" under pile throwing, using ferries to set up machines, employing water-study German machine makers. Underwater operation equipment, "dig eight feet four or five feet, remove the sand and gravel, exposed to the bottom. Then use the Russian long pine wood to nail plum piles, spread the long stone. The palace secret recipe to build the underground mausoleum's "million-year prison" three-in-one soil, after two years and eight months to be severe." The successful construction of the Luohe Railway Bridge made foreign engineers and technicians look at Zhan Tianyou. Jin Dat recommended him to join the British Civil Engineers Association and become the first Chinese member of the association. In 1976, the nearby road bridge was destroyed and the bridge was safe.
