An underground pipeline parameter measuring device and its measuring method

Abstract

The embodiment of the invention discloses an underground pipeline parameter measurement device and a measurement method thereof. The device comprises a telescopic rod, a first sensing ranging device, a pipeline peeping device, a transmission cable and a main control box, wherein the top end and the bottom end of the telescopic rod are respectively provided with the first sensing ranging device and the pipeline peeping device; the pipeline peeping device comprises a photographing device, a laser emitting device and a second sensing ranging device; and one end of the transmission cable is respectively electrically connected with the first sensing ranging device and the pipeline peeping device, and the other end is electrically connected with the main control box. The pipeline peeping device can extend to a to-be-measured pipeline as long as a worker controls the telescopic rod on the ground, parameters of the to-be-measured pipeline can be acquired, and the safety factor is high. In addition, based on a bow altitude and chord length method, the pipe diameter of the to-be-measured pipeline is calculated, and buried depth and pipe diameter parameters of the to-be-measured pipeline can still be accurately acquired even when the measured pipeline internally has deposit or an obstacle.

Description

technical field [0001] The invention relates to the technical field of underground pipeline monitoring, in particular to an underground pipeline parameter measurement device and a measurement method thereof. Background technique [0002] With the development of society and the continuous improvement of the current level of urbanization in my country, urban infrastructure is developing rapidly, and underground pipelines are becoming more and more complex. The renewal of old pipelines and the design and planning of new pipelines all require various information about underground pipelines. During the detection or general survey of the underground pipeline system, the pipe diameter and buried depth are two important parameters that need to be measured, among which: the pipe diameter refers to the diameter of the inner wall of the underground pipe, and the buried depth refers to the vertical height from the bottom of the underground pipe to the ground. Usually, a tape measure or...
