Foundation pit supporting structure combined by section steel and precast concrete planks
The invention discloses a foundation pit supporting structure combined by section steel and precast concrete planks. The foundation pit supporting structure comprises double-spliced section steel, the precast concrete planks and cement-soil mixing piles. The cement-soil mixing piles are arranged on the outer side of the foundation pit; the double-spliced section steel comprises H-shaped steel and batten plates, the number of the H-shaped steel is two, the H-shaped steel is arranged in parallel at a fixed interval, and the two sides of the H-shaped steel are fixedly connected through the batten plates; the prefabricated concrete planks are inserted between every two adjacent double-spliced section steels, and gaps are reserved between the prefabricated concrete planks and the double-spliced section steels; the prefabricated concrete planks are reinforced according to the deformation and stability requirements of foundation pit excavation; the double-spliced profile steel and the prefabricated concrete planks are arranged on the sides, facing the interior of the foundation pit, of the cement-soil mixing piles. The profile steel piles adopted by the invention are in a double-splicing type, the thickness of the precast concrete planks can be adjusted, the rigidity of the whole structure can be higher after the reinforcements are arranged as required, and the cantilever is suitable for foundation pit engineering with various excavation depths or various soil layer properties after being combined with an inner support or an anchor cable.
本发明公开了一种型钢与预制混凝土板组合的基坑支护结构，包括：双拼型钢、预制混凝土板、水泥土搅拌桩；所述水泥土搅拌桩布置在基坑外侧；所述双拼型钢包括H型钢和缀板，所述H型钢有两根，间隔固定距离平行放置，两边通过多块所述缀板固连；相邻两双拼型钢之间插入所述预制混凝土板，所述预制混凝土板与双拼型钢之间保留空隙；所述预制混凝土板根据基坑开挖的变形及稳定性要求按需配筋；所述双拼型钢和预制混凝土板布置在所述水泥土搅拌桩朝向基坑内部的一侧。本发明所采用的型钢桩为双拼型式，预制混凝土板的厚度能进行调节，按需配筋后能使整体结构刚度更大，悬臂或与内支撑或锚索结合后适用于多种开挖深度或多样土层性质的基坑工程。
