Construction method of square steel plate caisson on local deep foundation of water-containing quicksand layer
The invention discloses a construction method of a square steel plate caisson on a local deep foundation of a water-containing quicksand layer, belongs to the technical field of building construction, and can solve the problems that water bursting and collapse are easy to occur in the construction of a local elevator shaft and a water-collecting well foundation pit with a higher underground water level and a foundation layer just located in water-containing quicksand. The method comprises the following steps of caisson drawing design, steel plate blanking, seam splicing and welding, water pump placing and dewatering at the four corners of a foundation pit, truck crane hoisting in place, box body position and standard height checking, box body interior dewatering and concrete pouring, inner support dismantling, caisson interior cleaning and cushion layer pouring. The system is suitable for residential engineering with elevator shafts and water-collecting wells located below the underground water level.
一种方形钢板沉箱在含水流沙层局部深基础的施工方法，属于建筑施工技术领域，可解决在地下水位较高且基础层恰好位于含水流沙的局部电梯井、集水井基坑施工中，容易出现涌水且容易塌陷等问题，本发明步骤如下：沉箱图纸设计→钢板下料、拼缝、焊接→基坑四角放置水泵降水→汽车吊吊装就位→箱体位置、标高校核→箱体内部降水、浇筑混凝土→拆除内撑→沉箱内部清理、浇筑垫层，适用于电梯井和集水井位于地下水位之下的住宅工程。
