Problems solved by technology

[0004] Aiming at the problems in the prior art, the purpose of the present invention is to provide a long-distance oil and gas pipeline laying and installation construction method, which solves the existing problem that the foundation pit is excavated when the foundation pit is excavated, and the ground of the base is excavated. Uneven, excavated uneven foundation pit bottom surface, it is easy to cause uneven force on the connection of two adjacent pipelines, and it is easy to break the joint of oil and gas pipelines buried in the foundation pit for a long time, affecting the safety of oil and gas pipelines technical issues

Abstract

The invention discloses a method for laying and installing long-distance oil and gas pipelines, and relates to the technical field of building construction. The method for laying and installing long-distance oil and gas pipelines specifically includes the following steps: S1. Excavating foundation pits: excavating on the ground For the foundation pit for laying oil and gas pipelines, the opening of the foundation pit faces upwards, and the wall of the foundation pit is perpendicular to the bottom of the foundation pit; S2. Installing the base: place the foundation pit for supporting the oil and gas pipelines in the foundation pit that has been excavated in step S1. Base, place multiple bases, and fix the two adjacent bases at equal intervals on the bottom of the foundation pit; S3, pipeline placement: place multiple oil and gas pipelines near the foundation pit that has been excavated in step 1 , place the oil and gas pipeline parallel to the foundation pit. In the present invention, a number of equidistant threaded holes are provided on the top of the support base, so that the distance between the support ribs on both sides of the top of the support base can be adjusted, which is convenient for adaptive adjustment according to the different diameters of oil and gas pipelines .

Description

technical field [0001] The invention relates to the technical field of energy transmission and construction, in particular to a long-distance oil and gas pipeline laying, installation and construction method. Background technique [0002] The oil and gas pipeline is a pipeline used to transport fluid substances such as oil or natural gas. The oil and gas pipeline is connected end to end by a multi-section pipeline to connect an oil circuit for internal fluids to flow and transport in the pipeline. When installing oil and gas pipelines, in order to avoid pipeline damage during use, the oil and gas pipelines are often buried underground, and the oil and gas pipelines are buried inside by digging holes on the ground to improve the protection of the oil and gas pipelines. [0003] In the existing oil and gas pipelines, since the oil and gas pipelines need to be used for long-distance transportation, a long foundation pit must be excavated on the ground when installing the oil an...
