Composite foundation pit supporting pile
The invention relates to the technical field of foundation pit supporting and aims to solve the problem that it is strenuous to pull out a supporting pile out of a soil layer, in particular to a composite foundation pit supporting pile which comprises a supporting pile body, a folding driving mechanism is arranged in the supporting pile body, and the cross section perimeter of the supporting pile body can be controlled through the folding driving mechanism. A supporting part used for improving the bearing capacity of the supporting pile is arranged on the supporting pile body, the length of the supporting part is larger than any section of the length of the cross section of the supporting pile body, and the supporting part is located outside the supporting pile body in the working state and located inside the supporting pile body in the non-working state. According to the supporting pile, the second column body is driven to be close to the first column body, the cross section perimeter of the supporting pile body composed of the first column body and the second column body is reduced, the contact face of the first column body and the pit wall is reduced, a constructor can easily pull out the supporting pile body through a machine, and damage to the supporting pile body is avoided.
本发明涉及基坑支护技术领域，针对支护桩拔出土层费力的问题，具体是涉及一种复合式基坑支护桩，包括有支护桩本体，支护桩本体的内部设置有收拢驱动机构，通过收拢驱动机构可以对支护桩本体的横截周长进行控制，支护桩本体上设置有用以提高支护桩承压能力的支撑部，支撑部的长度大于支护桩本体横截面长度的任意一段，支撑部工作状态时处于支护桩本体外部，支撑部非工作状态时处于支护桩本体的内部，本申请通过驱动第二柱体靠近第一柱体，由第一柱体和第二柱体组成的支护桩本体的横截周长缩小，第一柱体与坑壁的接触面缩小，施工人员便可以通过机器轻松的将支护桩本体拔出并避免对支护桩本体造成的损伤。
