Underground pipeline detection method

Abstract

The embodiment of the invention discloses an underground pipeline detection method, which can be used for conveniently determining the position of a pipeline to be detected by burying an identification belt underground in advance as a standard object. The depth of the identification belt and the vertical origin corresponding to the identification belt on the ground are determined through two detection processes; a detector is placed on the vertical origin to send a radar signal; depth information and position information of the to-be-detected pipeline are determined by combining a direct connection method, two times of positioning of one pipeline are further achieved by arranging the detector and sending radar signals at a first point, two times of positioning information are combined, accurate positioning of the pipeline is achieved, and therefore the position relation between the to-be-detected pipeline and the identification belt is determined. According to the detection information, a profile position relation graph of the identification belt and the to-be-detected pipeline is drawn. The detection method is simple, efficient and high in detection accuracy, non-excavation underground pipeline detection is achieved, manpower and material resources are saved, and the position relation between the pipeline and the identification belt can be accurately drawn.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of detection technology, and in particular to a detection method for underground pipelines. Background technique [0002] With the continuous development of the city, it is often necessary to carry out construction work to a certain depth underground, such as laying new pipelines. In order not to damage the existing underground pipelines when laying new pipelines, pipeline detection is often required. The purpose is to quickly and accurately detect the location of underground water pipes, metal pipes, cables, etc. without damaging the ground cover. , direction, depth, and the location and size of the damaged point of the anticorrosion layer of the steel pipeline. [0003] In the prior art, it is only possible to detect the type, quantity, depth, etc. of buried underground through the underground pipeline detector, but the position of the pipeline and the positional relationship between...

Problems solved by technology

[0003] In the prior art, it is only possible to detect the type, quantity, depth, etc. of buried underground through the underground pipeline detector, but the position of the pipeline and the positional relationship between the pipelines can only be roughly estimated, and the relationship between them cannot be accurately determined. The positional relationship between them leads to poor detection accuracy and limited help for on-site construction personnel.
