A clip-type detachable underground pipeline monitoring device

Abstract

The invention discloses a clip-type detachable underground pipeline monitoring device, which includes a monitoring well dug on the ground surface and located directly above the pipeline, and two clips. The two clips are vertically inserted downwards into the ground and connected to the ground The pipeline is tangent, the bottom cover of the monitoring well is provided with a cover plate, the clip is a hollow structure and a side groove is opened on the side close to the pipeline, a sliding plate is slidably connected in the side groove, and the clip A first motor is fixedly connected to the inner wall of the sheet, and a screw shaft is fixedly connected to the output shaft of the first motor. The advantage is that the monitoring well in the invention is located directly above the pipeline. When the micro motor is activated during installation, the two synchronous gears will be driven to rotate. The hole protrudes and is tightly attached to the outer wall of the pipeline under the action of its own elasticity. The same sensor is also attached to the outer wall of the pipeline, which can better measure the displacement of the pipeline.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to a clip-type detachable underground pipeline monitoring device. Background technique [0002] With the continuous construction and development of the city, there are more and more tall buildings and deep foundation pit projects, which will inevitably affect the underground pipelines of the surrounding roads. Once an accident occurs in the pipeline, it will cause poor social impact and even endanger the personal and property safety of the masses. During the construction process of the project, the underground pipelines within the scope of construction influence are often monitored, the construction is guided in a timely manner, and corresponding preventive measures are taken to ensure the safety of the project and pipelines. Therefore, how to effectively, accurately and conveniently monitor underground pipelines is the focus of monitoring work. [0003] At present, the commonly ...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used underground pipeline monitoring devices are divided into two categories. The first category is the indirect method. Spikes are placed near the ground above the pipeline to be monitored, and the deformation of the pipeline is recorded by monitoring the settlement or uplift of the spikes. The disadvantages of this method What the road spikes respond to is the deformation of the soil. Due to the difference in the elastic modulus of the soil and the pipeline, there is a large error in the deformation of the two, and it cannot truly reflect the deformation of the pipeline. Therefore, we propose a method that can be accurate and timely A clip-type detachable underground pipeline monitoring device for detecting the safety of the bottom line pipeline
