Inclined slope pipe-jacking hole-exiting construction method
The invention discloses an inclined slope pipe-jacking hole-exiting construction method, and belongs to the technical field of municipal pipeline pipe jacking. The problems that a traditional pipe-jacking hole-exiting method is high in cost, large in construction difficulty and large in influence on the surrounding environment in the construction period are solved. The inclined slope pipe-jacking hole-exiting construction method comprises the steps that before pipe-jacking construction, a sleeve valve pipe is adopted to perform pre-reinforcement on stratums at the end and the top of a to-be-built jacking pipe in a ground grouting mode; pipe-jacking construction is carried out through a pipe jacking tool, and pipe-jacking construction is stopped when the jacking pipe is jacked to be close to the inclined slope surface; sloping and back digging are carried out from the slope face to the pipe jacking direction, so that the pipe jacking tool and the end of the pipe jacking are exposed; the pipe jacking tool is hoisted to leave a construction site, and other structures connected with the jacking pipe are constructed; and backfilling and soil covering are carried out, and grass and trees are planted to recover the original natural landform. According to the inclined slope pipe-jacking hole-exiting construction method, the problems of safety and feasibility of pipe jacking slope holing are solved in the mode of stratum pre-reinforcement and reverse excavation backfilling, the method is easy and convenient to construct, a pipe jacking receiving well is prevented from being built and dismantled, and the engineering cost and risk are low.
本发明公开了一种倾斜坡地顶管出洞的工法，属于市政管道顶管技术领域，解决了传统的顶管出洞方法存在的费用高、施工难度大、施工期间对周边环境影响大的问题。本发明方法：顶管施工之前，先采用袖阀管通过地面注浆的方式对拟建顶管的端部和顶部位置的地层进行预加固；利用顶管工具进行顶管施工，待顶管顶进至临近倾斜坡面时停止顶管施工；自坡面向顶管方向放坡反挖，使顶管工具及顶管端部暴露；吊运顶管工具离开施工现场，并施做与顶管衔接的其他构筑物；回填覆土，植草种树恢复原本自然地貌。本发明采用“预加固地层+反挖回填”的方式来解决顶管斜坡出洞的安全性和可行性问题，该方法施工简便，避免修筑和拆除顶管接收井，工程费用和风险低。
