Rectangular pipe jacking construction method for outlet and inlet channel of subway station
The invention provides a rectangular pipe jacking construction method for an outlet and inlet channel of a subway station. The construction method specifically comprises the steps of constructing an initial well and a receiving well, calculating and determining jacking parameters, smearing wax on the outer wall of a pipe before jacking, connecting a head of a pipe jacking machine and three adjacent pipe sections into a whole during jacking, simultaneously injecting pressure injection thixotropic slurry into the back of the pipe sections in the jacking process, and arranging a stopping device to prevent the pipe jacking machine from retreating; erecting a receiving platform to receive the pipe jacking machine, after the jacking construction is finished, plugging pipe section gaps and the gaps between the pipe sections and two end openings, and finally adding cement slurry to replace the thixotropic slurry to consolidate a pipe jacking channel. It is ensured that the underground pipelinedoes not settle, crack, leak or the like, and compared with construction of a traditional open excavation method, the construction method has the advantages of small environmental impact, safe construction, simple operation, single procedure, low manufacturing cost, cost saving and good popularization significance.
本发明提供了一种地铁车站出入口通道的矩形顶管施工方法。该施工方法具体依次包括始发井、接收井的施工，计算和确定顶进的参数，顶进前对管外壁涂抹蜡，顶进时将顶管机机头与其相邻的三节管节连接为一个整体，顶进过程中同时向管节背后注入压注触变泥浆，并设置止退装置防止顶管机后退；搭设接收平台接收顶管机，顶进施工完成之后，对管节间隙及管节与两端洞门间的间隙进行封堵，最后加注水泥浆对触变泥浆进行置换，固结顶管通道。本发明保证了地下管线不沉降、不开裂、不泄露等，且相比传统明挖法施工，该施工方法对环境影响小、施工安全、操作简单，工序单一，造价低，节约成本，具有较好的推广意义。
