Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a reusable foundation pit slope supporting mechanism. Background Art

[0002] In the construction process of building projects, it is a very important step to reinforce the slope of the foundation pit. The slope of the foundation pit is reinforced by the foundation pit slope support mechanism to avoid the occurrence of slope sliding, collapse and other phenomena. The foundation pit slope support mechanism usually consists of two parts, namely the support plate and the anchor rod.
