Recently, the second lining of the Changlinggang Tunnel of the Third Division of Yongliu Expressway undertaken by China Railway Seventh Bureau was successfully poured for the first time. This is the first version of the second lining pouring of the whole tunnel of the project, marking that the construction of the Changlinggang Tunnel has entered a new stage and laying the foundation for the steady progress of the subsequent main construction of the tunnel.
Changlinggang Tunnel is located in Dongquan Town, Liucheng County, Liuzhou City, and is a control project for the whole line. In order to ensure the smooth completion of the pouring of the first second lining concrete, the project department has organized and held special safety technical disclosure meetings for many times, sorted out the pouring process, strictly controlled important links such as section review, reinforcement safety, embedded parts inventory, pouring vibration, etc., formulated a guarantee list, and tightened the main responsibility for compaction.
Yongliu Expressway is an important section of the "13 verticals" of Guangxi Expressway Network Planning (2018-2030), which will further improve the Guangxi Expressway network and the Pan-Pearl River Delta regional road network, provide convenient travel roads for Liuzhou North Ecological New Area in Liuzhou City, and is of great significance for promoting regional economic development and driving the development of industries and tourism along the route.
