Municipal pipeline laying construction process

Abstract

The invention relates to a municipal pipeline laying construction process. The process comprises the following steps of S1, route planning, wherein a construction route is planned; S2, straight pipeline prefabrication, wherein a straight pipeline is prefabricated according to the constructed route; S3, corner connecting pipe prefabrication, wherein a corner connecting pipe is prepared, and the corner connecting pipe comprises two connecting discs and at least one stainless steel hose fixedly connected between the two connecting discs; S4, trench excavation, wherein an outer trench is excavated according to the construction route; S5, straight pipeline and corner connecting pipe splicing, wherein the straight pipeline and the corner connecting pipe are connected and sealed; S6, corner connecting pipe reinforcing, wherein the outer side of the corner connecting pipe is sleeved with a polymer hose, concrete is injected into the polymer hose, the outer side of the stainless steel hose of the corner connecting pipe is wrapped with the concrete, and the concrete is waited to be condensed; and S7, trench soil filling, wherein the trench is filled with soil. The process has the effects that the connection of the corner connecting pipe and the straight pipeline is guaranteed, and the situation that the straight pipeline connection is affected by prefabrication errors is avoided.

Description

technical field [0001] The present application relates to the field of pipeline construction, in particular to a municipal pipeline laying construction process. Background technique [0002] Municipal pipelines are one of the important components of urban infrastructure, including cable pipelines, natural gas pipelines, water conservancy pipelines, etc. Cable ducts are used to store cables to realize the power supply of urban facilities; natural gas pipelines are used to transport natural gas to realize the use of buildings in cities; water conservancy pipelines can be divided into water pipelines and drainage pipelines, and drainage pipelines can remove urban ground rainwater in time, providing urban Provide industrial and domestic water while preventing urban water resources from being polluted. Municipal pipelines should have sufficient strength and rigidity, have certain corrosion resistance and sufficient airtightness. [0003] At present, in the construction of munic...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that because the pipelines are prefabricated in advance and then transported to the construction site for construction, there will be a certain error between the actual size of the pipeline and the size required for laying, especially the corner connecting pipe of the pipeline. Often there will be errors between the actual laying requirements and the prefabrication requirements, resulting in a deviation in the corner angle of the corner connecting pipe, which will make the pipes unable to be connected, and the corner connecting pipe needs to be re-prepared, and the previously prepared pipe joints will also be unusable. On the one hand Waste of resources, on the one hand, also prolongs the construction period
