Recyclable combined steel structure open caisson and construction method thereof
The invention relates to the technical field of steel structure open caissons, in particular to a recoverable combined type steel structure open caisson and a construction method thereof.The recoverable combined type steel structure open caisson comprises four steel corner columns symmetrically arranged in pairs and four well walls, the well walls are installed between every two adjacent steel corner columns, and the four steel corner columns and the four well walls are combined and installed to form the steel structure open caisson; the concept of combined assembly is adopted, steel structure open caisson components are manufactured and machined in a factory and assembled on the ground of a construction site to form a rigid structure, an open caisson sinks in place according to a conventional open caisson construction technology, after non-excavation construction of a pipeline is completed, earthwork is backfilled in the open caisson while connecting pieces of the wall of the steel open caisson are dismantled, and the open caisson is constructed. And finally, the steel member is pulled out on the ground for recycling, so that the minimum influence on the surrounding environment and the minimum risk in the construction process are guaranteed, the enclosure structure and the permanent structure are combined into a whole, the economical efficiency is good, and the quality is high.
本发明涉及钢结构沉井技术领域，具体为一种可回收组合型钢结构沉井及其施工方法，包括四根两两对称设置的钢角柱和四片井壁，井壁安装在相邻两根钢角柱之间，四根钢角柱和四片井壁组合安装形成钢结构沉井，本发明采用组合装配的概念，将钢结构沉井构件在工厂制作加工，施工现场地面组装形成刚性结构，按常规沉井施工技术将沉井下沉到位，在完成管道的非开挖施工后，在沉井内边回填土方边拆除钢沉井井壁的连接件，最后在地面将钢构件拔出回收再利用，从而保证了施工过程对周围环境影响最小、风险最小，且围护结构和永久结构合二为一，经济性好、质量高。
