Problems solved by technology

[0005] In view of the problem in the prior art that stress concentration and damage are likely to occur when the installed pipeline is shaken, resulting in poor overall application effect of the pipeline construction method, the purpose of the present invention is to provide a construction process for pipeline laying, through It is necessary to paint the elastic rubber protective layer on the inner wall of the hole where the pipeline is installed to solve the above technical problems. It makes the installed pipeline less likely to be damaged due to stress concentration, and has a good application effect as a whole

Embodiment 1

[0034] Embodiment 1: a kind of construction technology of pipeline laying, it specifically comprises the following steps:

[0035] Step 1: Preparation of construction materials, preparation of construction machinery and common materials, inspection and acceptance of pipelines, preparation of construction plans, and technical disclosure and safety disclosure to construction personnel;

[0036] Step 2, hanger installation, using expansion bolts to fix the movable hanger and anti-shake hanger on the wall, and the movable hanger is set on both sides of the expansion joint, settlement joint or seismic joint, and the anti-shake hanger is set on the movable the outer sides of the hangers away from each other;

[0037] Step 3, hole treatment, grinding and cleaning the inner wall of the hole where the pipeline needs to be pierced, and then painting the elastic rubber protective layer on the inner wall of the hole, and waiting for it to cure;

[0038] Step 4, pipeline installation, set...

Embodiment 2

[0041] Embodiment 2: A construction process for laying pipelines. The difference from Embodiment 1 is that in step 2, a flexible telescopic tube connecting the pipeline is provided between the movable hanger and the anti-shake hanger, and the flexible telescopic tube Both ends of the pipe are fixed on the pipe by flanges.

Embodiment 3

[0042] Embodiment 3: A construction process for laying pipelines. The difference from Embodiment 1 is that, in Step 4, the pipelines are located at both ends of the holes and provided with square compensators.

Abstract

The invention discloses a pipeline laying construction process and relates to the technical field of pipeline construction. The problem that the overall application effect of a pipeline construction method is not good due to the fact that mounted pipelines are prone to causing stress concentration and being damaged during swaying is solved. The method comprises the following steps of step one, construction material preparation, step two, hanger mounting, step three, hole treatment, step four, pipeline mounting, and step five, sealing molding. According to the pipeline laying construction process, the inner side wall of a hole needing to be provided with a pipeline in a penetrated mode is ground and subjected to ash removal, then an elastic rubber protective layer is brushed on the inner side wall of the hole and solidified, the pipeline at an expansion joint or a settlement joint or a seismic joint is not liable to cause stress concentration when swaying, the pipeline is not prone to being damaged during use, and the whole method has a good application effect.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, more specifically, it relates to a construction technology for pipeline laying. Background technique [0002] Pipeline engineering is a comprehensive project that applies a variety of modern science and technology. It includes not only a large number of general construction and installation projects, but also some specialized engineering buildings, professional equipment and construction techniques. [0003] In the Chinese invention patent application document with the publication number CN107035915A, a ventilation duct construction method is disclosed, which includes the following steps: Step 1, air duct production: use flanging riveting method to connect the rectangular air duct with the angle steel flange, the rectangular air duct The pipe and the angle steel flange are riveted with galvanized rivets; Step 2, bracket and hanger installation: the bracket and hanger are installed a...
