Foundation pit supporting structure with prefabricated high-strength concrete thin-wall steel pipe piles
The invention discloses a prefabricated high-strength concrete thin-wall steel pipe pile foundation pit supporting structure, relates to the technical field of geotechnical engineering, solves the problem that recycling of prefabricated high-strength concrete thin-wall steel pipe piles is difficult to achieve, is built in a soil body where a pre-excavated foundation pit is located, and comprises a plurality of steel pipe piles and water stop piles. A first pile hole allowing the water stop pile to be formed through concrete pouring is formed in the soil body, the multiple steel pipe piles are arranged in the first pile hole at intervals, the auxiliary piles are used for assisting the steel pipe piles to be inserted into the first pile hole, and the isolation assemblies are used for isolating the steel pipe piles from concrete. A second pile hole is formed in the bottom of the first pile hole after the auxiliary pile is inserted into the first pile hole, the auxiliary pile is sleeved with the steel pipe pile, the isolation assembly comprises an isolation air bag, and the steel pipe pile is sleeved with the isolation air bag. According to the supporting structure, the soil retaining and water stopping effects of the supporting structure can be guaranteed, and meanwhile the steel pipe piles can be conveniently recycled.
本申请公开了一种预制高强混凝土薄壁钢管桩基坑支护结构，涉及岩土工程的技术领域，改善了预制高强混凝土薄壁钢管桩的可循环利用实现较为困难的问题，其搭建于预挖基坑所在位置的土体内，包括若干钢管桩以及止水桩，所述土体内开设有供止水桩由混凝土浇筑成型的第一桩孔，若干所述钢管桩间隔设置于第一桩孔中，还包括若干用于辅助钢管桩插入第一桩孔中的辅助桩以及若干用于将钢管桩与混凝土隔离的隔离组件，所述辅助桩插入第一桩孔后于第一桩孔的底部形成第二桩孔，所述钢管桩套设于辅助桩上，所述隔离组件包括隔离气囊，所述隔离气囊套设于钢管桩上。本申请能够在保证支护结构的挡土止水效果的同时，方便钢管桩实现可循环利用。
