Prefabricated test block back pressure foundation excavation supporting system and construction method
The invention provides a prefabricated test block back pressure foundation excavation supporting system and a construction method. The supporting system comprises a plurality of supporting piles, a plurality of prefabricated test blocks, a plurality of soil remaining areas and a concrete bottom plate, wherein the plurality of supporting piles are distributed in a circumferential direction of a foundation excavation; the concrete bottom plate is located at the bottom of the foundation excavation, and a distance is formed between the concrete bottom plate and the supporting piles; and the prefabricated test blocks and the soil remaining areas are located between the supporting piles and the concrete bottom plate and are alternately arranged in the circumferential direction of the foundation excavation at intervals. According to the prefabricated test block back pressure foundation excavation supporting system, the plurality of supporting piles, the plurality of prefabricated test blocks, the plurality of soil remaining areas and the concrete bottom plate are arranged, back pressure can be formed on the foundation excavation through the prefabricated test blocks, and therefore foundation excavation collapse is avoided, so as to ensure that an enough supporting effect is provided for the foundation excavation; and meanwhile, the prefabricated test block back pressure foundation excavation supporting system is simple in structure, low in manufacturing cost and short in construction period.
本发明提供一种预制试块反压基坑的支护体系及其施工方法，包括：多个支护桩、多个预制试块、多个留土区域及混凝土底板；多个所述支护桩沿基坑的周向分布；所述混凝土底板位于所述基坑的底部，且与所述支护桩具有间距；所述预制试块及所述留土区域位于所述支护桩与所述混凝土底板之间，且沿所述基坑的周向交替间隔排布。本发明的预制试块反压基坑支护体系通过设置多个支护桩、多个预制试块、多个留土区域及混凝土底板，可以借助预制试块对基坑形成反压，从而避免基坑坍塌，以确保为基坑提供足够的支护作用；同时，本发明的预制试块反压基坑支护体系结构简单，造价较低，施工周期较短。
