Completion of concrete pouring for bottom sealing of steel hanging box of main pier bearing platform of Yantan Reservoir Bridge of Baqiang Expressway

On March 6, after nearly 30 hours of continuous struggle, the concrete pouring of the steel hanging box bottom of the main pier bearing platform of Yantan Reservoir Bridge, which was constructed by Guangxi Jiaotong Construction Engineering Group Co., Ltd., was successfully completed, with a volume of 2688 cubic meters, marking that the Yantan Reservoir Bridge formally entered the stage of construction of the main pier bearing platform. The successful sealing of the steel box of the main pier cap has achieved the goal of the key process node construction period of the project and laid a solid foundation for the subsequent construction of the cable tower.

Lu Shuqi, the bottom sealing of the steel box of the main pier bearing platform is a key process in the construction of the whole bridge. In order to ensure the smooth progress of the bottom sealing construction of the main pier bearing platform steel hanging box, before the bottom sealing, the project held several special meetings on the bottom sealing concrete construction, and carefully deployed and closely organized the construction plan, material and equipment supply plan, personnel deployment plan and safety emergency plan. In the process of pouring, the leadership system is implemented, special personnel are arranged to follow up and inspect, the personnel of various departments are on duty continuously, the surveyors are on duty in real time, the safety personnel are on duty throughout the whole process, and the elevation of underwater concrete sealing is strictly controlled to ensure the construction quality.
