Construction method of foundation pit waterproof curtain in water-rich stratum area
The invention relates to a construction method of a foundation pit waterproof curtain in a water-rich stratum area, and is applied to the field of foundation pit waterproofing. The method comprises the following steps: constructing a steel sheet pile, determining the position of a steel sheet pile hole site and drilling to form the steel sheet pile hole site, inserting the steel sheet pile into the hole site and fixing, constructing a jet grouting pile, drilling the jet grouting pile hole site, and performing high-pressure jet grouting by a jet pipe to form the jet grouting pile. A reinforcing mechanism construction step: after the jet grouting pile is solidified, excavating a soil layer in the gap to form a mounting groove for mounting a reinforcing piece, fixing the reinforcing mechanism in the mounting groove and propping between the jet grouting pile and the steel sheet pile, and propping one end of the reinforcing mechanism on the connecting mechanism; and after the other end of the reinforcing mechanism abuts against the outer wall of the jet grouting pile, the mounting groove is backfilled with earthwork. The steel sheet pile has the effects that the possibility of sealing failure of the steel sheet pile is reduced, the sealing performance of the steel sheet pile is improved, and the reinforcing mechanism is used for assisting the steel sheet pile in supporting the side wall of the foundation pit, so that the pressure bearing capacity of the steel sheet pile is higher.
本申请涉及一种富水地层区基坑止水帷幕的施工方法，应用在基坑防水领域。其包括钢板桩施工步骤，确定钢板桩孔位的位置并钻孔形成钢板桩孔位，钢板桩插入孔位中固定，旋喷桩施工步骤，钻取旋喷桩孔位，喷管进行高压喷射注浆，形成旋喷桩；加强机构施工步骤，旋喷桩凝固后开挖间隙中的土层形成用于安装加强件的安装槽，加强机构固定在安装槽内并抵撑在旋喷桩与钢板桩之间，加强机构的一端抵撑在连接机构上，加强机构的另一端抵撑在旋喷桩的外壁上后安装槽以土方回填。本申请具有降低了钢板桩的密封失效的可能，提升了钢板桩的密封性，并且利用加强机构辅助钢板桩对基坑的侧壁起到支撑作用，使得钢板桩的承压能力更强的效果。
