Embodiment 1
[0023] A pipe-drawing installation method for passing pipelines, the diameter of the engineering pipeline to be installed is 300mm, and the following steps are carried out in sequence:
[0024] Pipeline setting out → excavation of guide trenches → production of pipelines → jacking of conduits → connection of wire ropes → pulling of conduits and wire ropes → pulling of casings → penetration of engineering pipes and installation, the specific steps are:
[0025] When excavating the guide ditch 2, excavate the guide ditch 2 on both sides of the obstacle 1 to be crossed, and fix the limit pile 3 in the guide ditch 2.
[0026] When making pipes, conduits such as figure 1 As shown, the diameter is 1 / 5 to 1 / 3 of the diameter of the engineering pipeline to be penetrated, and the diameter is 100 mm. The catheter is divided into two parts: the front duct 11 and the rear duct 12. All have threading hole 101, the rear portion of front conduit 11 and the front portion of rear conduit 12 a...
