Receiving well steel pipe open caisson construction method
The invention belongs to the technical field of steel pipe open caisson construction, and discloses a receiving well steel pipe open caisson construction method which comprises the following steps: (1) according to a pipe jacking receiving well construction technological process, construction of each construction process is carried out successively; (2) manufacturing a steel pipe; (3) drilling and soil taking by the rotary drilling rig; (4) placing a first section of steel pipe; (5) taking soil in the steel pipe, reaming and sinking the steel pipe; (6) butting and sinking the steel pipes; (7) repeating the steps (5) and (6) until the steel pipe sinks in place, welding channel steel for preventing the steel pipe from sinking on the ground as required, and fixing the steel pipe; the receiving well steel pipe open caisson construction equipment comprises a steel pipe main body, supporting plates are arranged on the outer wall of the steel pipe main body, pushing assemblies are arranged at the bottom ends of the supporting plates, and the supporting plates are connected through connecting assemblies, so that the stability of the steel pipe main body during open caisson construction is improved; compared with a mode of directly welding a plurality of channel steels on the outer wall of the steel pipe main body, the installation efficiency is higher.
本发明属于钢管沉井施工技术领域，且公开了一种接收井钢管沉井施工方法，包括以下步骤：(1)按顶管接收井施工工艺流程，逐次进行每道施工流程的施工；(2)钢管制作；(3)旋挖钻机钻孔取土；(4)第一节钢管安放；(5)钢管内取土、扩孔、下沉钢管；(6)钢管对接、下沉；(7)重复第(5)、(6)步骤，直至钢管下沉到位，视需要在地面焊接防钢管下沉的槽钢，固定钢管；应用于一种接收井钢管沉井施工设备，包括钢管主体，所述钢管主体的外壁设置有支撑板，所述支撑板的底端设置有推动组件，所述支撑板之间通过连接组件连接，提高钢管主体沉井施工时的稳定性，相对于将多个槽钢直接焊接在钢管主体外壁的方式，安装效率更高。
