Pipe jacking launching construction method of bent pipeline
The invention provides a pipe jacking launching construction method of a bent pipeline. The method comprises the following steps of (S1) arranging a bending launching shaft at a bending point on a construction line according to the construction line of to-be-excavated bent pipelines; (S2) obtaining lengths of the to-be-excavated bent pipelines on two sides of the bending point, and defining a one-way construction section and a two-way construction section; (S3) arranging a two-way launching shaft on a construction line of the two-way construction section; (S4) arranging a bending jacking wallin the bending launching shaft, and arranging a two-way jacking wall in the two-way launching shaft; (S5) assembling pipe jacking equipment on one side, facing the one-way construction section, of thebending jacking wall, and respectively assembling pipe jacking equipment on two sides of the two-way jacking wall; and (S6) starting pipe jacking launching after the pipe jacking equipment is assembled. According to the pipe jacking launching construction method, the problem that pipe jacking construction cannot be normally executed due to the fact that two ends of a bent pipeline do not have thecondition of operating an launching shaft due to construction environment limitation and the bent pipeline in pipe jacking construction has bending is solved.
本发明提供一种弯折管道的顶管始发施工方法，包括以下步骤：S1)根据待开挖弯折管道的施工线路，在施工线路上的折弯点处设置折弯始发井；S2)获取弯折点两侧的待开挖弯折管道的长度，定义单向施工段和双向施工段；S3)在双向施工段的施工线上设置双向始发井；S4)在折弯始发井内设置折弯顶推墙，以及在双向始发井内设置双向顶推墙；S5)在折弯顶推墙朝向单向施工段的一侧组装顶管设备，以及在双向顶推墙的两侧分别组装顶管设备；S6)在顶管设备组装完成后开始顶管始发。本发明提供的顶管始发施工方法，解决了弯折管道两端因施工环境限制不具备施做始发井的条件且因顶管施工的弯折管道中具有弯折，造成顶管施工不能正常执行的问题。
