Deep foundation pit supporting structure and deep foundation pit construction method

HONG QIMING / HUANG CHUHE

The invention relates to the field of foundation pit supporting, in particular to a deep foundation pit supporting structure and a deep foundation pit construction method, and the deep foundation pit supporting structure comprises a supporting pile body, an instant supporting mechanism and a supporting plate. The supporting pile body plays a role in supporting a foundation pit, the supporting mechanism plays a role in supporting the supporting pile body, and the supporting plate plays a role in enlarging the supporting range of the supporting pile body. The supporting pile body is arranged close to the waterproof curtain pile body, and the instant supporting mechanism can support the supporting pile body in time in the excavation process, so that the effect of supporting while excavation can be achieved in the excavation process of the deep foundation pit. The foundation pit supporting device has the effect that the problem that in the related technology, in the foundation pit excavation process, the foundation pit is prone to being damaged when supporting is not carried out in time is solved to a certain extent.

本申请涉及基坑支护领域，尤其是涉及一种深基坑支护结构及深基坑施工方法，包括支护桩本体、即时支撑机构和支撑板。支护桩本体起到对基坑进行支护的作用，即时支撑机构起到对支护桩本体进行支撑的作用，支撑板起到增大支护桩本体的支护范围的作用。支护桩本体靠近止水帷幕桩体设置，即时支撑机构能够随着开挖的过程即时对支护桩本体进行支撑，从而使得深基坑开挖的过程中能够达到一边开挖一边支护的效果。本申请具有一定程度上解决了相关技术中基坑开挖的过程中容易出现还没来得及进行支护，基坑就发生破坏的问题的效果。
