Construction method of underwater foundation pit
The invention discloses a construction method of an underwater foundation pit. The construction method comprises the steps that a continuous wall on the periphery of a foundation pit is constructed, and an upper layer supporting structure is constructed in the continuous wall; a steel sheet pile is constructed at a first position below the upper-layer supporting structure, the upper end of the steel sheet pile is located above the underground water level, and the lower end of the steel sheet pile is inserted below the horizontal position of the fourth support; underground water is continuously pumped and drained from the interior of the steel sheet pile to the exterior of the steel sheet pile, so that the interior of the steel sheet pile is kept in a pumping-dry state, and a fourth support at the first position is constructed in the steel sheet pile in the pumping-dry state; and the steel sheet piles continue to be constructed at the next position below the upper-layer supporting structure, water is continuously drained in the steel sheet piles, and fourth supports at the next position are constructed in the steel sheet piles in the draining state till the fourth supports at all the positions are constructed. According to the technical scheme, construction safety is guaranteed, construction procedures are simple, the structure is stable and reliable, and the upper limit of the underwater excavation depth of the foundation pit is improved.
本申请公开了一种水下基坑的施工方法。所述施工方法包括：施作基坑四周的连续墙，并在连续墙内施作上层支撑结构；在上层支撑结构下的第一位置处施作钢板桩，使钢板桩的上端位于地下水位以上，下端插入第四道支撑的水平位置以下；从钢板桩内向钢板桩外持续抽排地下水，使钢板桩内保持抽干状态，在抽干状态下的钢板桩内施作第一位置处的第四道支撑；在上层支撑结构下的下一位置处继续施作钢板桩，对钢板桩内进行持续排水并在抽干状态下的钢板桩内施作下一位置处的第四道支撑，直至所有位置的第四道支撑施作完毕。根据本申请的技术方案，保证了施工的安全，施工工序简单、结构稳定可靠，提高了基坑水下开挖深度上限。
