Construction method for backfilling engineering of flow-state solidified soil backfilling steel sheet pile supporting pipeline
The invention discloses a construction method for backfilling engineering of a steel sheet pile supporting pipeline by backfilling fluid-state solidified soil. The construction method comprises the steps of steel sheet pile driving, earth excavation, steel sheet pile supporting, foundation pit sand foundation, pipeline anti-floating, pouring and fixing, pile pulling, re-pouring of the fluid-state solidified soil, pulling out of the steel sheet pile, maintenance and the like. According to the construction method, the floating problem of the pipeline in the construction process is solved by adopting the flow-state solidified soil, the in-situ gap filling problem during pile pulling and after pile pulling is backfilled by using the flow-state solidified soil, the slurrying and grouting processes after pile pulling are simplified, the pipeline engineering construction process is optimized, and the technical effects of simplifying the construction process are achieved.
本发明公开一种流态固化土回填钢板桩支护管道回填工程的施工方法，包括钢板桩打桩、土方开挖、钢板桩支撑、基坑砂基础、管道抗浮、浇筑固定、拔桩，再次浇筑所述流态固化土，并将所述钢板桩拔出和养护等步骤。本申请采用流态固化土解决了施工过程中管道的上浮问题，且使用流态固化土回填了拔桩时和拔桩后原位的空隙填充问题，简化了拔桩后的制浆，注浆过程，优化管道工程施工工艺，简化施工流程的技术效果。
