Description

technical field

[0001] The invention relates to the technical field of pipeline detection, in particular to an integrated system and method for underwater pipeline detection. Background technique

[0002] In the field of underwater pipeline detection engineering, the current domestic method is to combine sonar, GPS and the buried pipeline anti-corrosion layer detector produced by British Radiodetection Company for on-site detection. Sichuan Vocational and Technical College of Water Conservancy Zhou Xiaoli and others published a paper on the GPS-RTK technology-based detection method for crossing river pipelines (1672-4623 (2016) 03-0099-03) on geospatial information in May 2016. The GPS-RTK technology's external detection method for crossing river pipelines uses DM pipeline anti-corrosion layer detectors, depth sounders, GPS, total stations, etc. to build an external detection system for crossing pipelines to realize the detection of crossing river pipelines.

Embodiment Construction

[0050] like Figure 2-5 As shown, an integrated system and method for underwater pipeline detection described in the embodiment of the present invention:

[0051] 1) On-site preparation, including the analysis of the width of the river and the depth of the river, and the determination of the positions of the test piles at both ends of the river;

[0052] 2) The erection of GPS RTK;

[0053] 3) After the installation of the GPS base station is completed, when the data starts to be collected, start to connect the cables to the two nearest test piles at both ends of the river, and connect the electromagnetic signal transmitter in series in the loop to ensure that it forms a loop with the pipeline;

[0054] 4) Pairing of handheld PDA (mobile phone) and mobile antenna;

[0055] 5) For data collection of onshore pipelines at both ends of the river, a point is generally measured every 6-10 meters, and dots are made on the corners and signposts of each pipeline;

[0056] 6) Select ...
