Steel sheet pile support notch treatment method for construction foundation trench
The invention discloses a notch treatment method for constructing a foundation trench steel sheet pile support, which comprises the following steps: S1, firstly constructing a support steel sheet pile in a trench area to be excavated, downwards excavating for a certain distance after the steel sheet pile is constructed for a certain length, then constructing well point dewatering, and welding and mounting a steel enclosing purlin and a steel pipe support; s2, the comprehensive pipeline transversely penetrating through the groove is excavated and exposed, and a steel plate is inserted into quicksand soil above the comprehensive pipeline after being attached to a steel plate pile through a pile driver; s3, earthwork between the steel sheet pile and the steel sheet is cleaned, and then the steel sheet pile and the steel sheet are welded together; and S4, steel bar meshes are installed on the steel sheet piles and the steel plates below the pipelines, then a steel wire mesh is bound, and finally concrete is sprayed to the steel wire mesh and covers the steel plates. A large amount of earthwork above the pipeline is blocked by the steel plate, and a small amount of earthwork and external water at the lower part are blocked from entering the groove by using the reinforced steel wire mesh sprayed concrete, so that the conditions of groove earthwork collapse, water leakage and the like are avoided.
本发明公开了一种用于施工基槽钢板桩支护缺口处理方法，包括以下步骤：S1、待开挖沟槽区域先施工支护钢板桩，待钢板桩施工完成一定长度后向下开挖一定距离再施工井点降水，焊接安装钢围檩以及钢管支撑；S2、将横穿沟槽段综合管线开挖显露出，通过打桩机将钢板贴着钢板桩后边插到综合管线上方的流沙土中；S3、清理钢板桩与钢板间的土方，随后将钢板桩与钢板焊接到一起；S4、管线下方的钢板桩与钢板上先安装钢筋网片，再绑扎一张钢丝网，最后将混凝土喷射到钢丝网上并覆盖在钢板上。本发明通过钢板挡住管线上方大量土方，下部再利用钢筋钢丝网喷射混凝土挡住下部少量土方及外部水进入沟槽，避免了沟槽土方塌方、渗漏水等情况出现。
