Fabricated profile steel combined foundation pit supporting method
The invention belongs to the technical field of foundation pit supporting, and particularly relates to a fabricated profile steel combined foundation pit supporting method. After SMW construction method pile construction is completed, steel bars of a top beam are welded to the top end of a SMW construction method pile, and then the top beam is poured; steel bar connectors are spot-welded on the parts, extending out of the top beam, of embedded steel bars in the top beam, and are connected with profile steel enclosing purlins through screws; profile steel brackets are welded to one side of an embedded steel plate, profile steel supports are installed at the tops of the profile steel brackets, and the profile steel supports are connected with the profile steel enclosing purlins through bolts; steel support triangular pieces are arranged at the oblique crossing positions of the profile steel supports and the profile steel enclosing purlins; and profile steel stand columns are arranged in the centers of the profile steel supports, the bottom ends of the profile steel stand columns are embedded in cast-in-place piles, brackets are welded to embedded steel bars of the profile steel supports, and a cross beam is connected with each profile steel support through high-strength bolts. The manufacturing cost is low, the quality is easy to control, and the energy consumption is greatly reduced; and the construction space is reduced, the construction efficiency is improved, the construction speed is high, stress loss is effectively prevented, and safety is guaranteed.
本发明属于基坑支护技术领域，具体涉及一种装配式型钢组合基坑支护方法。本发明SMW工法桩施工完成后在其顶端焊接冠梁的钢筋，然后浇筑冠梁；冠梁中的预埋钢筋伸出冠梁的部分点焊钢筋连接器，钢筋连接器通过螺杆连接型钢围檩；在预埋钢板的一侧焊接型钢牛腿，在型钢牛腿的顶部安装型钢支撑，型钢支撑与型钢围檩用螺栓连接；在型钢支撑与型钢围檩的斜交处设置钢支撑三角件；在型钢支撑的中央设置型钢立柱，型钢立柱的底端预埋在灌注桩内，托座与型钢支撑的预埋钢筋焊接，横梁与每道型钢支撑之间通过高强螺栓连接。本发明造价低、质量易于控制，大大降低了能耗；减少施工空间，提高施工效率，施工速度快，有效防止应力损失，保证了安全。
