Foundation pit supporting structure and construction method thereof
The invention discloses a foundation pit supporting structure and a construction method thereof, the foundation pit supporting structure comprises a cement pile wall and profile steel inserted in the cement pile wall, the upper end of the profile steel extends out of the top of the cement pile wall, the profile steel is sleeved with a positioning structure, the positioning structure comprises a spiral steel wire, the spiral steel wire is arranged on the profile steel in a sleeving mode, and the spiral steel wire is connected with the cement pile wall. A limiting part is arranged at the lower end of the spiral steel wire and abuts against the lower end face of the profile steel, supporting drill rods are arranged on the spiral steel wire in the length direction of the spiral steel wire at intervals, and the supporting drill rods abut against the side face of the profile steel. The two adjacent supporting drill rods are staggered by a central angle smaller than or equal to 90 degrees relative to the central line of the spiral steel wire. The positioning effect can be enhanced after the profile steel is inserted into the cement-soil mixture which is not hardened yet.
本申请公开了一种基坑支护结构及其施工方法，基坑支护结构，包括水泥桩墙和插设于水泥桩墙的型钢，所述型钢的上端伸出所述水泥桩墙的顶部，所述型钢套设有定位结构，所述定位结构包括螺旋钢丝，所述螺旋钢丝套设于所述型钢，所述螺旋钢丝的下端设有设有限位部，所述限位部抵接所述型钢的下端面，所述螺旋钢丝沿自身长度方向间隔设置有支撑钎杆，所述支撑钎杆抵接所述型钢的侧面，相邻两个支撑钎杆之间相对所述螺旋钢丝的中心线错开小于或90度的中心角。本申请能够使型钢插入尚未硬结的水泥土混合体后的定位效果得到加强。
