Full-assembly type large-span steel structure soft soil deep foundation pit supporting structure and construction method thereof
According to the full-assembly type large-span steel structure soft soil deep foundation pit supporting structure, steel sheet piles serve as a retaining structure for retaining soil and water, profile steel standardized components are assembled to form a horizontal truss structure to serve as a horizontal support, and the horizontal support comprises angle braces and prestressed enclosing purlins; the prestress enclosing purlin and the angle brace are connected into a whole, the stress axis of the prestress enclosing purlin and the stress axis of the angle brace are located on the same plane, and a pressure-adjustable pressurizing device is arranged on the angle brace. The prestressed enclosing purlin comprises a lower chord beam, a web member is arranged on the lower chord beam and extends to the inner side of the foundation pit, a steel strand is arranged at the top of the web member, the two ends of the steel strand are connected with the two ends of the lower chord beam, and the steel strand and the lower chord beam form a closed fish-bellied structure; the lower chord beam clings to the steel sheet piles. The structure has the advantages of an assembled structure, high rigidity, large span, controllable deformation, convenience in construction, environment friendliness and the like, and materials are recycled.
本发明提供的全装配式大跨度钢结构软土深基坑支护结构，采用钢板桩作为挡土和止水的围护结构，采用型钢标准化构件装配形成水平桁架结构作为水平支撑，水平支撑包括角撑以及预应力围檩；所述预应力围檩和角撑连成整体，预应力围檩和角撑受力轴线在同一平面上，角撑上设置有压力可调的加压装置；预应力围檩包括一下弦梁，下弦梁上设置有腹杆，腹杆伸向基坑内侧，腹杆顶部设置有钢绞线，钢绞线的两端与下弦梁的两端连接，钢绞线与下弦梁形成一个闭合的鱼腹式结构；下弦梁紧贴钢板桩布置。该结构具有装配式结构、刚度大、跨度大、变形可控、施工方便、材料回收循环使用绿色环保等优点。
