Steel sheet pile foundation pit supporting construction method in sandy soil layer environment
The invention discloses a steel sheet pile foundation pit supporting construction method in a sandy soil layer environment. The steel sheet pile foundation pit supporting construction method comprisesthe following steps that a water jet cutter is connected with a pressure conveying steel pipe; the pressure conveying pipe is fixed; a power pump is connected with the pressure conveying pipe; an infrared laser lamp is mounted at the pile top; female pile guide holes and conventional piles are inserted; positioning and paying off are conducted on a foundation pit for steel sheet pile construction; according to the placed positioning line, an excavator is adopted for stripping a pond slag layer and large stone blocks which are backfilled on the surface; a steel sheet pile construction positioning line is pulled and fixed, and handed over to a pile driver and a pile supporting worker; the water jet cutter mother pile is connected with a high-pressure water pump, commissioning and debuggingare performed, and whether the whole device runs normally or not is checked; a water jet cutter mother pile is driven; a conventional pile is replaced for driving; and repeated constructing is performed according to the method until the Larsen steel sheet pile is completed. The sandy soil layer at the original pile position is disturbed through the high-pressure water steel sheet piles, construction of the steel sheet piles in the sandy soil layer is achieved, the steel sheet piles are not damaged, the construction cost is reduced, the construction progress is accelerated, and the constructionquality is guaranteed.
本发明公开了一种砂质土层环境下钢板桩基坑支护施工方法，包括以下步骤：水刀与输压钢管连接；输压管固定；动力泵与输压管连接；桩顶安装红外线激光灯；母桩引孔及常规桩插入；对用于钢板桩施工的基坑进行定位放线；根据所放的定位线，采用挖掘机剥去表面回填的塘渣层及大石块；拉设固定好钢板桩施工定位线，并对桩机司机及扶桩工交底；将水刀母桩与高压水泵连接好并试运行调试，检查整个装置是否运行正常；水刀母桩开打；换来常规桩开打；按照上述方法反复施工，直至拉森钢板桩完成。本发明采用高压水钢板桩对原桩位的砂质土层进行扰动，实现钢板桩在砂土层中的施工并且不损坏钢板桩，降低施工成本，加快了施工进度，保证了施工质量。
