Embodiment

[0024] Refer to attached figure 1 As shown, the present invention provides a technical solution: a construction method for non-stop navigation and relocation of airport pipelines, including pipeline detection, GPS three-dimensional positioning, BIM underground pipeline comprehensive arrangement and instantaneous switching.

[0025] Step S1, pipeline detection: use ground penetrating radar to conduct non-destructive detection of existing underground pipelines, which can be used to find and mark the positions of various cables and pipelines, and assist manual excavation of trenches or holes for review;

[0026] In this embodiment, each working procedure is:

[0027] S1a, site investigation: After the preparation work is completed, refer to the existing drawings, technical files, etc., to familiarize yourself with the site conditions, understand the surrounding important buildings and facilities, sort out the types of pipelines and their protection levels;

[0028] S1b, non-dest...

Abstract

The invention provides a construction method for non-stop navigation and relocation of airport pipelines, which belongs to the technical field of pipeline relocation and reconstruction construction. The construction method for non-stop navigation and relocation of airport pipelines includes pipeline detection, GPS three-dimensional positioning, and BIM underground pipeline comprehensive arrangement And instantaneous switching, S1, pipeline detection: use ground penetrating radar to conduct non-destructive detection of existing underground pipelines, which can be used to find and mark the positions of various cables and pipelines, and assist manual excavation of trenches or holes for review; S2, GPS Three-dimensional positioning: After the pipeline detection is completed, the three-dimensional coordinates of the straight line section, inflection point, and inspection well of the pipeline are locked by the GPS three-dimensional positioning system installed outside the equipment, achieving higher positioning accuracy and providing reliable data for the establishment of BIM models for subsequent pipeline relocation. The invention innovatively solves the construction problem of relocation and modification of non-stop pipelines in the flight area of ​​the airport, the construction speed and construction quality are greatly improved compared with the traditional method, and the reliability of construction is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, and in particular relates to a construction method for non-stop relocation of airport pipelines. Background technique [0002] At present, there are more and more airport reconstruction and expansion projects. Such projects often have difficulties such as complex types of existing underground pipelines, incomplete or inaccurate historical data for reference, and heavy coordination workload due to the involvement of multiple pipeline ownership departments. Conventional construction methods cannot realize the relocation under the condition of continuous water supply and power failure, and the construction speed is slow. At the same time, due to force majeure or human factors, there is a certain deviation between the actual construction of the original pipeline and the drawing design, which makes the original pipeline easy to be damaged during the relocation process. , cannot effective...
