C4 standard for connecting pipe project of water source area in the upper reaches of Huangpu River |
Case classification: construction case of slurry balance pipe jacking machine Construction unit: tunnel shares municipal group set top company |
By December 29th the tunnel shares municipal group's construction of the upper reaches of the Huangpu River top water pipe engineering C4 the first section of four meters to 841 meters of steel pipe is completed through, marking the Qingpu, Jinshan, Songjiang, Minhang, Fengxian and other regions of the people drink water quality on the upper reaches of the Huangpu River is a step closer. The connecting pipe at the end of December 2014 the project started, the plan by the end of 2016 with water conditions, and gradually put into operation. |
The company contracted by the Huangpu River water set-top pipe engineering C4 is the largest caliber (four m diameter) of the steel pipe jacking project, the first section of the 15-16 interval in Yangzhou Xin Guang heavy manufacturing DN4000 slurry balanced pipe jacking machine in September 28th officially began to push forward, the daily average speed of 2 knots, which lasted for three months completed through. C4 standard is the first project of the whole section of pipe engineering, undertake to export a total of 3.177 kilometers Songjiang Xietang station connected pipe construction tasks at the junction of Liantang from Songjiang. Pipe jacking construction method is a kind of non excavation of underground engineering, the jacking force in the jack at work well, to overcome the friction of the soil around the pipe and steel pipe, a steadily to four meters underground pipe into the top soil, between the pipe section by welding together, finally formed sending high-quality raw water pipe transportation. Connected pipe C4 mark project has six working wells and five sections of steel pipe jacking, the longest pipe jacking distance is 1061 meters, there is a section through the national highway G60 highway 18-16 section, pipe jacking 379 meters (diameter 4.2 meters). At present, the project technicians are paying close attention to the construction progress of the working shaft, and plans to start the National Road jacking after the Spring Festival next year, so as to ensure the completion of the construction of the pipe jacking project with a total length of 3.17 kilometers in June next year. |
