The invention relates to the technical field of building construction, in particular to a foundation pit support construction method which comprises the following steps: slotting and driving steel sheet piles; conveying the piles to the designed elevation; excavating earth to the bottom of the steel support, and arranging a steel support system; arranging an earth surface drainage system; excavating the foundation pit to the bottom of the raft cushion layer in a layered mode; arranging a raft plate cushion layer, a brick moulding bed and a concrete support changing plate belt; binding steel bars, and pouring foundation concrete; after the foundation concrete is solidified, dismantling the steel supports; constructing an outer wall and a top plate of the underground pool; backfilling soil to the top elevation of the steel sheet pile; pulling out the steel sheet pile; and backfilling the soil to the original ground height. According to the construction method, the steel sheet pile can be rapidly pulled out, and the construction period of the foundation pit is effectively shortened.
本申请涉及建筑施工技术领域，更具体地说，它涉及一种基坑围护施工方法，包括以下步骤：开槽、打设钢板桩；送桩到设计标高；挖土至钢支撑的底部，设置钢支撑体系；设置地表排水系统；基坑分层开挖到筏板垫层的底部；打设筏板垫层、砖胎模和砼换撑板带；绑扎钢筋，浇筑基础混凝土；待基础混凝土凝固后，拆除钢支撑；进行地下池外墙和顶板施工；回填土至钢板桩顶标高；拔除钢板桩；回填土至地面原高度。本申请的施工方法能使钢板桩快速拔除，有效缩短基坑的施工周期。
