Problems solved by technology

In the prior art, the underground pipeline detection device includes a transmitter and a receiver, and adopts a single-point coverage detection method. This method can only measure the straight-line distance between the underground pipeline and the detection device, and it is difficult to determine the specific location of the underground pipeline. The positioning accuracy is poor, and it is difficult to meet the detection requirements of small-diameter polyethylene pipelines

Abstract

The invention discloses an underground pipeline detection device. The objectives of the invention are to improve underground pipeline detection positioning precision and acquire specific distributioninformation of underground pipelines. The device comprises a support, a controller, at least two signal emitters and at least two signal receivers, wherein the controller, the signal emitters and thesignal receivers are installed on the support. The signal emitters and the signal receivers are connected with the controller. The signal receivers are used for receiving signals emitted by the signalemitters. The controller is used for extracting signals reflected by the underground pipelines from the signals received by the signal receivers, and acquiring position information of the undergroundpipelines according to the reflected signals.

Description

technical field [0001] The invention relates to the technical field of underground pipeline detection, in particular to an underground pipeline detection device. Background technique [0002] With the development of science and technology, the process of urban construction is gradually accelerating. In urban planning and construction, it is necessary to have a detailed understanding of the distribution and specific location information of underground pipelines. For pipelines that have been built for a long time, a lot of information is incomplete, so manual detection is required to determine the distribution and specific location information of underground pipelines. [0003] The material, pipe diameter, and buried depth of underground pipelines all have a great influence on the difficulty of detection. In particular, for polyethylene pipelines with small diameters and large buried depths, detection is difficult, especially for pipes with diameters smaller than 200mm, poly...
