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 the pipeline, the conduit, as shown in Figure 1, has a diameter of 1 / 5 to 1 / 3 of the diameter of the project pipeline to be penetrated, and the diameter is 100mm. The conduit is divided into two parts, the front conduit 11 and the rear conduit 12. The front conduit 11 The rear portion of the front and rear conduit 12 is provided with a threading h...

Abstract

The invention relates to the pipeline construction method field of a metallurgy system, in particular to a pull pipe mounting method of a passing pipeline, which comprises the following steps of: unreeling a pipeline; digging pilot trenches; making the pipeline; popping conducts; connecting steel wires; pulling the conducts and the steel wires; pulling sleeves; and penetrating and mounting a construction pipe. The pull pipe mounting method of a passing pipeline is characterized in that when the conducts are popped, the front conduct is popped in by top pressing equipment (4); and then, the rear conduct (12) is popped in; and when the sleeves are pulled, the conducts and the sleeves are connected, the front conduct (11) is pulled, and the rear sleeve (22) is popped in until the front sleeve (21)passes out of a pilot trench (2) at the other side. The invention has low construction cost, short construction period, high mounting quality and high production efficiency.

Description

technical field [0001] The invention relates to the field of pipeline construction methods for metallurgical systems, in particular to a pipe-drawing installation method for passing pipelines. Background technique [0002] In pipeline construction projects, if there are no obstacles, slotting construction can be used, but pipelines often need to pass through roads, railways, buildings, rivers, etc., in this case, slotting construction is usually not allowed or the difficulty of slotting construction and The investment is relatively large, and the pipe jacking method is usually used for construction when it is impossible or difficult to open grooves. The pipe jacking method is a kind of underground excavation construction method used when underground pipelines pass through various obstacles such as railways, roads, rivers or buildings. After entering the working pit, use the hydraulic jack supported on the back seat of the foundation pit to press the pipe into the soil layer...
