Embodiment 1

[0032] like figure 1 As shown, an installation method of a long-distance angle continuous gradient pipeline, the refrigeration pipeline 3 is arranged between the track support columns 10 below the national snowmobile sled center track 1, and the installation method includes the following steps:

[0033] Step S1, carry out stakeout measurement on the installation position of the pipeline 3, and determine the axial positioning of the pipeline thermal insulation support 4 and the pipeline support 2;

[0034] Step S2, according to the positioning of the track support column 10, combined with the drawing size of the pipeline 3 to determine the radial positioning of the pipeline, the pipeline thermal insulation support and the pipeline support;

[0035] Step S3, installing the pipeline thermal insulation support and the pipeline support;

[0036] Step S4, (3) In the building information model system BIM, the drawings are deepened, the pipeline is segmented according to the bending ...

Embodiment 2

[0042] An installation method of a long-distance angle continuous gradient pipe, the method steps of which are similar to those in Embodiment 1. Different from Embodiment 1, the pipeline is a heating pipeline.

[0043] In summary, the present invention discloses an installation method of a long-distance angle continuous gradient pipe, the pipe is arranged between the track support columns under the track, and the installation method includes positioning and installing the pipe insulation support and the pipe Bracket, segment the pipe according to the bending curvature of the pipe and set the angle of each bending position: the bending angle of the segmented pipe is controlled between 3° and 30°, and the segmented pipe is typesetting and blanking Process, number, and prefabricate the segmented pipelines described in the off-line prefabricated welding part, and perform non-destructive testing on the welded seams, transfer the prefabricated pipelines, and on-site welding and qual...

Abstract

The invention discloses an installation method of a long-distance angle continuous gradual change pipeline which is arranged between racing track supporting columns below a racing track. The installation method comprises the steps that a pipeline heat preservation support and a pipeline support are positioned and installed, the pipeline is segmented according to the bending curvature of the pipeline, and the angle of each bending position is set; the bending angle of the segmented pipeline is controlled to range from 3 degrees to 30 degrees; and off-line prefabricating the segmented pipeline of the welding part, carrying out nondestructive testing on a welded weld joint, transferring the prefabricated pipeline, carrying out field welding, carrying out quality inspection and the like. The pipeline installation method is simple and convenient, the problem of segmented installation of the long-distance pipeline below the racing track is effectively solved, the pipeline installation quality control is fused into the installation procedure while the pipeline is installed, the construction period is shortened, and the quality is guaranteed; and the device can be widely applied to installation of refrigeration pipelines and heating pipelines and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to an installation method of a long-distance angle continuous gradient pipeline. Background technique [0002] The track of the National Snowmobile Center has a total length of 1975 meters, a vertical drop of 121 meters, and contains 16 curves, one of which is a 360-degree slalom. The cooling main pipe is arranged between the track support columns below the track and is divided into two liquid supply pipes and return gas pipes. The direction of the pipeline is meandering with the layout of the track, and has the characteristics of long distance and continuous gradient. Since the angles of each section of the pipeline are different, it is difficult to complete the installation of the pipeline with high quality within the specified construction period by using the conventional pipeline installation method. [0003] The Chinese invention patent application with the appl...
