Embodiment 1

[0043] see Figure 1-7 , which is a schematic diagram of the overall structure of a method for laying and establishing a natural gas transmission pipeline project, a method for laying and establishing a natural gas transmission pipeline project, including the following steps:

[0044] S1. Excavate the foundation pit, excavate the foundation pit on the ground for laying the ground natural gas pipeline, the opening of the foundation pit faces upward, and the wall of the foundation pit is perpendicular to the bottom surface of the foundation pit;

[0045] S2, install the base, place the base for supporting the natural gas pipeline in the foundation pit that has been excavated in step S1, and install and fix the base on the middle position of the bottom surface of the foundation pit;

[0046] S3, pipeline preparation, placing the natural gas transmission pipeline near the foundation pit that has been excavated in step 1;

[0047] S4, pipeline installation, place the natural gas d...

Abstract

The invention discloses a method for laying and establishing a natural gas transmission pipeline project, which relates to the technical field of engineering construction and includes the following steps: S1. Excavating a foundation pit, excavating a foundation pit on the ground for laying a natural gas transmission pipeline on the ground, and opening the foundation pit facing upwards, the wall of the foundation pit is perpendicular to the bottom of the foundation pit; S2, install the base, place the base for supporting the natural gas pipeline in the foundation pit that has been excavated in step S1, and install and fix the base in the middle of the bottom of the foundation pit Position; S3, pipeline preparation, place the natural gas transmission pipeline near the foundation pit that has been excavated in step 1. In the present invention, the natural gas pipeline is quickly placed in the foundation pit through the rope, and the position of the natural gas pipeline placed in the foundation pit is extended through the extension of the brackets on both sides, so that the position of the natural gas pipeline placed in the foundation pit is fine-tuned, so that the natural gas pipeline and the base are more tightly fitted, and the natural gas pipeline is placed firmly. sex.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a method for laying and establishing a natural gas transmission pipeline project. Background technique [0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oil field gas, gas field gas, mud volcanic gas, coal bed methane, and biologically generated gas, etc.). [0003] After the natural gas is collected, it needs to be transported. The natural gas is transported to the destination through the pipeline. There are two ways to fix the natural gas pipeline, one is overhead, and the other is landfill. The natural gas pipeline is buried underground to ensure the safety of the natural gas pipeline. Transport safety. [0004] During the laying and construction of natural gas pipelines, due to the large volume of natural gas pipelines, the opera...
