Construction method for reconstruction and expansion of expansion pipe of drainage pipe network
The invention provides a drainage pipe network reconstruction and expansion pipe expansion construction method, and relates to the technical field of drainage pipe network reconstruction and expansion. According to the construction method, an inspection opening supporting frame, a connecting rod rotating traction device, a plurality of conical head connecting rods, a connecting conical head, an old pipeline crushing cutterhead assembly, a pipeline pulling and disassembling assembly and a plurality of rivet assemblies are included; the connecting rod rotation traction device comprises a connecting rod clamp, a clamp fixing bearing, an outer fixing frame, a clamp gear, a motor fixing frame, a transmission motor and a motor gear, the connecting rod clamp is connected to an inner supporting point of the clamp fixing bearing, and the outer fixing frame is connected to an outer supporting point of the clamp fixing bearing; the clamp gear is connected to the rear side wall of the connecting rod clamp. By means of the mode that the old pipeline is pulled to be broken, damage to a soil base layer by a pipe expansion method is avoided, a working well does not need to be excavated, and earth surface working space does not need to be reserved any more.
本发明提供一种排水管网改扩建胀拉管施工方法，涉及排水管网改扩建技术领域。该排水管网改扩建胀拉管施工方法，包括检查口支撑架、连接杆转动牵引装置、若干锥头连接杆、连接锥头、旧管道破碎刀盘组件、管道拉拆组件与若干铆钉组件，所述连接杆转动牵引装置包括连接杆夹具、夹具固定轴承、外固定架、夹具齿轮、电机固定架、传动电机与电机齿轮，所述连接杆夹具连接在夹具固定轴承的内支撑点上，所述外固定架连接在夹具固定轴承的外支撑点上，所述夹具齿轮连接在连接杆夹具的后侧壁上。通过将旧管道拉碎的方式，既避免了胀管法对土基层的破坏，也无需开挖工作井，不再需要预留地表工作空间。
