Problems solved by technology

This scheme has the following difficulties: 1. The space in the pipe gallery is narrow, the pipe joints are heavy, and the horizontal transportation and installation of the pipe joints are inconvenient; 2. After the pipe joints are in place, due to the limited clearance around them, manual welding can only be used, and the welding speed is relatively slow. Slow and the quality is not guaranteed, about 1 / 3 of the welding speed outside the hole
Therefore, using the above-mentioned conventional technical construction scheme to carry out pipeline assembly in the pipe gallery, the transportation and assembly of pipeline materials are inconvenient, and due to the limited space in the pipe gallery, it is not conducive to the welding of pipe joints, thereby reducing the construction efficiency of pipe assembly

Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0030] Such as Figure 1 to Figure 9As shown, a construction method for quick installation of pipelines in a pipe gallery provided in this embodiment, in order to facilitate the transportation and assembly of pipe joints, and speed up the construction efficiency of pipeline assembly. Further, the construction method for quick installation of pipelines in the pipe gallery includes step A of group welding of pipelines outside the gallery, step B of pipeline transportation in the gallery, step C of welding between groups of pipelines in the gallery, and step D of pipeline assembly. In the group welding step A, a plurality of pipe joints are welded into a pipe group 6 outside the pipe gallery 5, and then the pipeline transportation step B is adopted in the gallery, and a plurality of pulley blocks 1 for...

Abstract

The invention discloses a construction method for rapidly installing pipelines in a pipe gallery, and belongs to the technical field of pipeline engineering. An operator welds a plurality of pipe joints into a pipeline set outside the pipe gallery, then the pipeline sets are conveyed to preset assembling positions in the pipe gallery through a pulley set and a winch set, between-group welding is carried out the pipeline sets in the pipe gallery, finally, conveying pipes are jacked through a jacking unit, the pulley set and the winch set are dismantled, and the conveying pipelines are assembledon a buttress set. According to the construction method for rapidly installing the pipelines in the pipe gallery, the advantages of the speed and process stability of welding outside the pipe galleryare fully utilized, the welding work amount in the pipe gallery is reduced, the transportation speed in pipe joint holes is increased, and the pipeline assembling construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline engineering, in particular to a construction method for quickly installing pipelines in a pipeline gallery. Background technique [0002] Pipeline engineering is the construction of pipelines for transporting oil, natural gas, solid slurry, water and other materials, including pipeline line engineering, station warehouse engineering and pipeline ancillary engineering. In a broad sense, pipeline engineering also includes the supply of equipment and equipment. Among them, the pipeline line project is a project that uses pipes, pipe fittings, valves, etc. to connect the starting station, intermediate station and terminal station of the pipeline to form a pipeline transportation line, and is the main part of the pipeline project. [0003] During the construction of the pipeline line, the following conventional technical scheme is usually used for construction. During the construction, the operator n...
