Foundation pit supporting method for constructional engineering

WANG JINGYU

The invention relates to the technical field of foundation pit supporting, and discloses a foundation pit supporting method for constructional engineering, which comprises the following steps: S1, surveying a foundation pit, carrying out engineering geological survey on a foundation pit site, and entering an excavation stage after determining engineering conditions of the site; s2, foundation pit excavation is conducted, and excavation treatment is conducted on the surveyed site; and S3, foundation pit supporting is conducted, specifically, a supporting device is transferred into the foundation pit through a crane, the supporting device is fixed into the foundation pit, and the foundation pit is supported through the supporting device. According to the scheme, the problems that in an existing foundation pit supporting method, a supporting structure can only be used once, and the construction cost is high are mainly solved.

本发明涉及基坑支护的技术领域，公开了一种建筑工程的基坑支护方法，包括以下步骤：S1：基坑勘测，对基坑场地进行工程的地质调查，确定场地的工程条件后进入开挖阶段；S2：基坑开挖，对勘测后的场地进行开挖处理；S3：基坑支护，使用吊机将支护装置转运至基坑内，将支护装置固定在基坑内，通过支护装置对基坑进行支护。本方案主要解决了现有基坑支护方法中支护结构只能单次使用，施工成本高的问题。
