Changyi Changyi Changyi section officially entered the rail paving stage

Today (June 16), at the construction site of the Changde Station of Changyi Changchang Railway, the first pair of 500 -meter long rail passed the traction and push through the two trains. The Changyi section of the Changtai is officially entered the rail paving stage. Changyi Changchang Railway adopts cross -interval consistent seamless line construction. Among them, Changde Zhiyang section is more difficult, and the largest slope during the period reaches 20ths. At the same time, the construction of the rail engineering enters the high temperature season, the rails produce the heat expansion and contraction effect, and the rail locking orbit is high. This time, the Changye -Chang Railway Changye section, the main construction tasks of the rail paving contain the main line of the main line, the front rail is 163.257 kilometers, the station line paving is 13.47 kilometers, and 54 groups are laid on the road. At present, the Changye Chang Railway Yichang section has been completed as the main project of the first -section rail paving, and has successfully entered the joint testing stage.

Zhang Rantong, chief engineer of the three -point department of the Changyi Changchang Railway Project Department of China Railway 11th Bureau: Completed the rail engineering construction before September this year, completed the launch of the long track before the end of July, and the stress direction of the rails was locked in the late August. Four Electricity Projects and Joint Corporation Test for Preparation.
