Foundation pit excavation construction supporting method
The invention provides a foundation pit excavation construction supporting construction method which comprises the following steps that S1, a fence is arranged, a site is leveled, and a foundation pit is excavated in a preset area; s2, concrete is sprayed in a net mode while the side slope is excavated; s3, constructing a fender post, measuring and setting out a site in advance, pressing a pile casing into a set area, drilling the set area to form a hole, and installing a pre-woven reinforcement cage into the hole; s4, a crown beam and a concrete support are constructed, center lines and side lines of the crown beam and the concrete support are defined through surveying and setting out, then a set area is excavated, a formwork is erected after excavation, and concrete is poured; s5, latticed columns are constructed in the foundation pit; s6, concrete is sprayed to the construction face, and anchor rods are installed; s7, the plate rib type anchor rod retaining wall is constructed; and S8, soil is backfilled to the designed elevation of the ground, and the problem that in the prior art, in the foundation pit excavation process, an excavated construction face is not supported, and consequently the soil rock stratum collapses is solved.
本发明提供了一种基坑开挖施工支护工法，包括以下步骤，S1：设置围挡、场地整平，对预定区域开挖基坑；S2：边坡开挖的同时网喷混凝土；S3：施工围护桩，预先对场地进行测量放样，将护筒压入既定区域，对既定区域钻进成孔，将预先编制好的钢筋笼安装进孔内；S4：施工冠梁以及砼支撑，通过测量放线，定出冠梁以及砼支撑的中心线以及边线，然后对既定区域开挖，开挖后支立模板并灌注混凝土；S5：在基坑内施工格构柱；S6：对施工面喷射混凝土并安装锚杆；S7：施工板肋式锚杆挡土墙；S8：回填土至地面设计标高，其解决了现有技术中存在的在基坑开挖的过程中，还未对开挖的施工面进行支护，就出现了土质岩层坍塌的现象。
