钢结构换撑梁在内支撑基坑工程中的应用

APPLICATION OF STEEL STRUCTURE CHANGING BEAMS IN INNER SUPPORTING FOUNDATION PIT ENGINEERING

深圳市某基坑内支撑换撑体系采用一种可周转、可伸缩的钢结构换撑梁,与传统混凝土换撑梁相比,在施工工艺、进度、质量、成本等方面均有一定优势,且安装简单、可循环使用,解决了混凝土换撑梁结构支模困难的问题,还减少了资源投入节约了成本。

The support replacement system in a foundation pit in Shenzhen adopts a revolving and retractable steel structure replacement beam.Compared with traditional concrete replacement beams,it has certain advantages in construction technology,schedule,quality,and cost.The installation is simple and recyclable,which solves the problem of difficulty in supporting the formwork of the concrete supporting beam structure,and also reduces the resource input and saves the cost.
