The continuous beam of Haian super large bridge across Beiling river of Yantong railway is closed smoothly

Beijing, Nanjing, Oct. 28 (reporter Yang Bo correspondent Luo Guang) with the last concrete pouring completed, the continuous beam of Haian super bridge across Beiling river of Yantong railway was closed successfully on Oct. 28, marking that the construction of Yantong railway has entered a comprehensive speed-up stage, and the bridge deck construction will be expanded in a large area. The

Yantong railway is one of the main channels of the national "eight vertical and eight horizontal" high-speed railway, which complements the "missing important section" of China's coastal railway. The total length of the main line of the railway is 187.96 km, the track laying mileage is 156.66 km, and the design speed is 350 km / h. According to the relevant person in charge of China Railway Beijing Engineering Bureau, the bureau is responsible for the construction of lot ytzq-4 of Yancheng Nantong railway station front project, the main project is Hai'an super large bridge, with a length of 26098.89 extension meters, of which the continuous beam across Beiling river is the last continuous beam in the bid section.

it is understood that in the early stage of the construction of the continuous beam across the Beiling River, through the expert demonstration and scheme review, the construction scheme has been discussed and demonstrated for many times. Before the construction, as many as 13 construction procedures have been specifically disclosed, as well as an overall safety disclosure. The preparatory work is sufficient.

the staff of the project introduced that there was a gravity retaining wall underground in the excavation process. The retaining wall was designed for the original channel and intersected with 1006 × pier, which seriously affected the construction of pile cap. The project department urgently launched the emergency plan seminar. Through preliminary survey and survey drawing, the shotgun and excavator were organized to break the concrete structure and pull out the wooden pile. Through active response and efficient organization to ensure the smooth implementation of the construction work. The

Yantong railway is an important part of the first vertical coastal railway in the national "eight vertical and eight horizontal" high-speed railway network, and also an important traffic vein connecting the "belt and road" construction and the Yangtze River economic belt. Speeding up the construction of Yantong railway is of great significance to improve the national coastal railway artery, promote the integration of Jiangsu coastal areas into the Yangtze River Delta region, promote the revitalization of Northern Jiangsu and win the battle of poverty alleviation.
