Foundation pit support structure applied to construction of ground rail traffic station
The invention relates to the field of underground layer construction in subway construction, in particular to a foundation pit support structure applied to ground rail traffic station construction, which comprises an outer diaphragm wall and an inner diaphragm wall, and a plurality of reinforcing piles are poured at equal intervals along the extension direction of the side wall of a foundation pit on the part close to the outer diaphragm wall; an inner supporting framework is arranged between the outer diaphragm wall and the inner diaphragm wall; the inner supporting framework comprises longitudinal beams, the longitudinal beams are horizontally arranged and distributed in three layers, the inner supporting framework is divided into four layers by the three layers of longitudinal beams, and the height of the two lower layers of the inner supporting framework is larger than that of the two upper layers of the inner supporting framework; the stand columns are vertically arranged and are distributed in two rows in the length direction of the longitudinal beams; the two sides of the top plate and the two sides of the bottom plate are connected with the outer diaphragm wall and the inner diaphragm wall; and a row of foundation piles are distributed below the inner supporting framework. The waterproof structure has the effects of integrally improving the waterproof performance in the foundation pit and enhancing the strength of the side wall of the foundation pit so as to reduce the collapse risk of the foundation pit.
本申请涉及地铁建设中地下层施工的领域，尤其是涉及一种应用于地轨交通车站施工的基坑围护结构，其包括外地连墙与内地连墙，基坑靠近外地连墙的部分沿基坑侧壁的延展方向等间距浇筑有多根加固桩，外地连墙与内地连墙之间设置有内支撑架构；内支撑架构包括：纵梁，纵梁水平设置，分布有三层，三层纵梁将内支撑架构分为四层，内支撑架构的下方两层高度大于上方两层高度；立柱，立柱竖直设置且沿纵梁的长度方向分布有两排；顶板、底板，顶板与底板的两侧均与外地连墙与内地连墙连接；基础桩，基础桩于内支撑架构的下方分布有一排。本发明具有整体提高基基坑内部的防水性能，增强基坑侧壁强度以减小基坑坍塌的风险的效果。
