Novel anti-settling and anti-inclining underground comprehensive pipe rack structure in soft soil foundation and construction method of novel anti-settling and anti-inclining underground comprehensive pipe rack structure
The invention discloses a novel anti-settling and anti-inclining underground comprehensive pipe rack structure in a soft soil foundation. The novel anti-settling and anti-inclining underground comprehensive pipe rack structure comprises a comprehensive pipe rack arranged in a strip-shaped foundation pit, wherein Larsen steel sheet piles are arranged on the two sides of the strip-shaped foundationpit so as to support soil bodies on the two sides; the comprehensive pipe rack is arranged on a concrete cushion layer, and the concrete cushion layer is arranged on square root pile supporting seatsformed by pouring concrete; at least three oblique auxiliary piles are obliquely arranged on each of the front portion, the rear portion, the left portion and the right portion of each of root pile main piles correspondingly, and reinforcing steel bars are arranged in the root pile main piles and the oblique auxiliary piles; oblique pile holes are obliquely formed in the Larsen steel sheet piles,and oblique pile bodies are obliquely downwards arranged at the oblique pile holes; and the comprehensive pipe rack is formed by connecting a plurality of sections of branch pipe racks, two rows of oblique pile bodies are arranged on the left side and the right side of each section of branch pipe rack correspondingly, two oblique pile bodies are arranged in each row, and outward concrete extendingblocks are arranged on the side walls of the oblique pile bodies. The invention further provides a construction method of the structure. The structure and the method can effectively prevent the comprehensive pipe rack in the soft soil foundation from settling and inclining.
本发明公开了一种防沉降和倾斜的软土地基中地下综合管廊新型结构，包括设置于条形基坑内的综合管廊，条形基坑两侧均设置有拉森钢板桩以支撑两侧土体，综合管廊设置于混凝土垫层上，混凝土垫层设置于方形的由混凝土浇筑形成的树根桩支座上，树根桩主桩的前后左右分别斜向设置有至少三根斜向副桩，树根桩主桩和斜向副桩中均设置有钢筋，拉森钢板桩上斜向开设有斜向桩孔，斜向桩孔处斜向向下设置有斜向桩体，综合管廊由多段分管廊连接形成，每段分管廊左右各布置两排所述斜向桩体，每排各布置两根，斜向桩体的侧壁上具有向外的混凝土延伸块。本发明还提供了上述结构的施工方法。本发明的构造和方法能够有效防止软土地基中的综合管廊沉降和倾斜。
