Recyclable diagonal bracing compression-resistant steel pipe pile for foundation pit supporting
The invention relates to the technical field of foundation engineering, in particular to a recoverable diagonal bracing compression-resistant steel pipe pile for foundation pit supporting, which comprises a foundation pit fender post, a concrete bottom plate, a top beam and a steel pipe pile, the upper end of the steel pipe pile is fixed on the top beam, the lower end of the steel pipe pile is obliquely inserted into a soil layer, and the concrete bottom plate is provided with an outer sleeve at the position of the steel pipe pile. The steel pipe pile can be pulled out of the outer sleeve; the steel pipe pile comprises a recycling pipe and an anchoring pipe. The multiple recycling pipes are sequentially connected end to end through the arranged first connecting nodes, and the anchoring pipe is connected to the recycling pipe at the tail end through the arranged second connecting nodes. The diagonal bracing compression-resistant steel pipe pile is decomposed into the multiple pipe joints, the pipe joints are connected in two different joint modes to form the assembly type steel pipe pile structure, all recovery pipe joints except the anchoring pipe can be pulled out and recovered, and the recovery utilization rate of the steel pipe pile is increased.
本发明涉及基础工程技术领域，具体为一种用于基坑支护的可回收斜撑抗压钢管桩，包括：基坑围护桩、混凝土底板、冠梁、钢管桩，钢管桩上端固定于冠梁上，钢管桩下端倾斜地插入土层中，混凝土底板在钢管桩的位置设有外套管，且钢管桩可从外套管内拔出；钢管桩包括回收管和锚固管；回收管设置有多根，且多根回收管之间通过设置的第一连接节点首尾依次连接，锚固管通过设置的第二连接节点连接在最尾端的回收管上。本发明将斜撑抗压钢管桩分解成多个管节，各管节之间采用两种不同的节点形式连接形成装配式钢管桩结构，可实现除锚固管以外的所有回收管管节拔出回收，提高钢管桩的回收利用率。
