Engineering foundation pit supporting device

LI HAOPENG

The invention relates to the field of foundation construction, in particular to an engineering foundation pit supporting device which comprises a supporting plate, supporting units and connecting pieces, and the supporting plate is of a structure capable of being wound around the vertical axis; a plurality of supporting units are arranged, each supporting unit comprises a fixing plate, a sliding block, an elastic piece, a first supporting rod and a second supporting rod, the fixing plate is fixed to the supporting plate, and the sliding block is connected with the fixing plate through the elastic piece; the sliding block moves upwards to drive the first supporting rod and the second supporting rod to retract to the fixing plate, and the supporting plate can be rolled conveniently. After the supporting plate is unfolded, the sliding block pushes the first supporting rod and the second supporting rod to rotate under the action of the elastic piece till the second supporting rod is attached to the ground, the supporting plate can be supported by the first supporting rod and the second supporting rod, use is convenient, and operation is easy. The connecting pieces are inserted into the ground and connected with the two adjacent second supporting rods, and the supporting effect of the second supporting rods is further enhanced.

本发明涉及基础施工领域，具体涉及一种工程基坑支护装置，包括支护板、支护单元和连接件，支护板为可绕竖直轴线卷绕的结构；支护单元有多个，每个支护单元均包括固定板、滑块、弹性件、第一支撑杆和第二支撑杆，固定板固定于支护板，滑块与固定板通过弹性件连接；滑块向上移动带动第一支撑杆和第二支撑杆收回至固定板，便于支护板收卷。支护板展开后滑块在弹性件的作用下顶推第一支撑杆和第二支撑杆转动，直至第二支撑杆与地面贴合，即可实现第一支撑杆和第二支撑杆对支护板的支撑，使用方便，操作简单。连接件插入地面并连接相邻两个第二支撑杆，进一步加强第二支撑杆的支撑效果。
