Underground pipeline depth detection device

Abstract

The invention provides an underground pipeline depth detection device. The device comprises a bracket and a plurality of screw rods; the bracket is provided with a first flat plate, a second flat plate and a third flat plate, the plurality of screw rods sequentially penetrate out of the bracket from top to bottom, every two adjacent screw rods are connected through a detachable connecting mechanism, a driving mechanism is arranged between the first flat plate and the second flat plate, a fixing piece is arranged on the third flat plate, the fixing piece is provided with threaded holes matchedwith the screw rods, and the screw rods are connected through the threaded holes in a threaded mode. According to the underground pipeline depth detection device, the screw rods for depth measurementare of a split structure, the depth detection device is of a pure mechanical structure, the detection process is slightly affected by the environment, the detection result is visual and accurate, thedepth of a pipeline underground or in a water pool can be accurately measured, and the underground pipeline depth detection device is widely applied to existing pipeline construction.

Description

technical field [0001] The invention belongs to the field of pipeline construction, in particular to an underground pipeline depth detection device. Background technique [0002] During pipeline construction, especially after underground or underwater pipeline construction, it is necessary to detect the pipeline depth again. Existing underwater pipeline depth measurement mostly uses multi-beam depth sounders. When using this multi-beam measurement, the beam is interfered by other floating objects in the water. Therefore, the requirements for the detection environment are relatively high. Ultrasonic testing is mostly used for depth measurement of underground pipelines. This testing method is affected by the geological structure itself. Therefore, for deep pipeline measurement, ultrasonic testing also has the problem of difficult measurement due to the complex testing environment. At the same time, multi-beam and ultrasonic detection devices are more expensive, and the monito...

Problems solved by technology

Ultrasonic testing is mostly used for depth measurement of underground pipelines. This detection method is affected by the geological structure itself. Therefore, the measurement of deep pipelines also has the problem of difficult measurement due to the complexity of the detection environment.

At the same time, multi-beam and ultrasonic detection devices are more expensive, and the monitoring device itself also needs regular maintenance and maintenance, resulting in increased construction costs
