Foundation pit supporting system based on splayed I-shaped steel and construction method thereof
The invention relates to a foundation pit supporting system based on splayed I-shaped steel and a construction method thereof. The system comprises an inner support horizontally arranged in a foundation pit, wherein the inner support comprises two sections, namely a splayed I-shaped steel support and a steel pipe support; the splayed I-shaped steel support comprises a diagonal support and diagonal braces symmetrically arranged on two sides of the diagonal support; one end of each diagonal brace is fixed to a surrounding purlin or a crown beam in the foundation pit, and the other end of each diagonal brace is fixed to the side face of the diagonal support; one end of the diagonal support is fixed to the surrounding purlin or the crown beam in the foundation pit, and the other end of the diagonal support is connected with the steel pipe support; and the other end of the steel pipe support is fixed to the surrounding purlin or the crown beam in the foundation pit through a movable head. The novel inner support with one or two ends made of the splayed I-shaped steel is designed, so that the action range of each steel support is widened, the number of the inner supports is reduced, the cost is reduced, and the construction period is shortened; and meanwhile, the operation space in the foundation pit can be enlarged, more abundant operation conditions are reserved for large machinery, the earthwork outward transport and material feeding and discharging efficiency is improved, and a more efficient and economical foundation pit steel support system is realized.
本发明涉及一种基于八字工字钢的基坑支护体系及其构建方法，所述体系包括基坑内水平向设置的内支撑，内支撑包括八字型工字钢支撑与钢管撑两个节段；八字型工字钢支撑包括对撑及对撑两侧对称设置的斜撑；斜撑一端固定到基坑内的围檩或冠梁，另一端固定到对撑侧面；对撑一端固定到基坑内的围檩或冠梁，另一端与钢管撑连接；钢管撑的另一端通过活络头固定到基坑内的围檩或冠梁。本发明设计了一端或两端八字型工字钢新型内支撑，提高了每道钢支撑作用范围，减少了内支撑数量，减少成本、缩短工期，同时还可增大基坑内作业空间，给大型机械预留更加充裕的操作条件，提高土方外运与材料进出效率，实现更加高效、节约的基坑钢支撑体系。
