Ganzhou Yangmeidu Sewage Treatment Plant Zhangjiang Left Bank Sewage Main Pipeline Project
The project to construct the left-bank Zhangjiang River main sewer line (Shuixi section) from Yangmeidou to the Baita Wastewater Treatment Plant in Ganzhou City involves a tunnel passing under the Changgan Railway. The project begins at the intersection of Dongjiangyuan Avenue and Xiangjiang Avenue and ends at the Baita Wastewater Treatment Plant in Shuixi. The pipeline is located within the eastbound non-motorized vehicle lane, and the entire route will be constructed using pipe jacking methods, with the pipeline operating on a gravity flow system. One section of the pipeline must cross under the railway. This 180-meter-long section of the sewer line requires casing construction in accordance with regulatory standards. The outer pipe will be constructed using DN3000 reinforced concrete pipe via pipe jacking, while the inner pipe will consist of a DN2400 centrifugally cast fiberglass-reinforced plastic (GRP) pipe serving as a liner. The void between the two pipes will be backfilled using sand jetting.
