Construction method of soft soil foundation pit composite supporting structure
The invention discloses a construction method of a soft soil foundation pit composite supporting structure, and relates to the technical field of constructional engineering. The construction method of the soft soil foundation pit composite supporting structure specifically comprises the following steps that according to a design drawing, a structure axis, a reference elevation line, an axis position and an elevation, the structure axis, the reference elevation line, the axis position and the elevation are introduced into a construction layer, and whether a horizontal line and a vertical line directly intersect or not is checked in time. According to the construction method of the soft soil foundation pit composite supporting structure, high-pressure jet grouting slurry is combined with the steel sheet piles, locking gaps in construction of the steel sheet piles are filled, under the condition that the steel sheet piles are driven discontinuously, the method that the high-pressure jet grouting piles are inserted into the steel sheet piles after being formed is adopted, water leakage of a foundation pit can be prevented, and rigidity needed by supporting can be guaranteed. And the situation that construction is affected by excessive leakage in the soft soil foundation pit is avoided, so that the cost and time of dewatering and drainage of the foundation pit are reduced, the construction progress is accelerated, and meanwhile, the influence of dewatering in the foundation pit on surrounding buildings is greatly reduced.
本发明公开了一种软土基坑复合支护结构的施工方法，涉及建筑工程技术领域。该软土基坑复合支护结构的施工方法，具体操作如下：根据设计图纸和结构轴线、基准标高线，轴线位置和标高引入施工层内，及时检查水平线与垂直线直接是否存在交圈现象。该软土基坑复合支护结构的施工方法利用高压旋喷注浆浆体与钢板桩结合，填塞钢板桩施工中的锁口缝隙，在钢板桩施打不连续的情况下，采用高压旋喷桩成桩后插入钢板桩的做法，既能防止基坑漏水，又能保证支护所需的刚度。避免软土基坑内渗漏过大影响施工，从而减少了基坑降排水的费用和时间，加快了施工进度，同时也大大减少了基坑内部降水对周边建筑的影响。
