Listening rod for leakage detection of underground pipe network

Technical Field

The utility model relates to a technical field is looked after to underground pipe network and is leaked, concretely relates to underground pipe network looks for leakage with listening pole.

Background

In a pipe network buried underground, water leakage occurs in pipes due to problems in pipe quality or construction. In order to avoid digging out all the pipelines when the pipelines leak water, the leakage points are generally searched first, and then the positions of the leakage points are dug to maintain the pipelines. The current method of inspection is by using a listening stick.

At present, the mainstream method for detecting the water leakage point is to probe abnormal sound emitted by the water leakage point so as to find out the accurate position of the water leakage point. The water leakage sound is generated in the following process that after the pressure-bearing pipeline is broken, water rapidly flows out from the broken opening, and the broken opening of the pipeline is impacted and vibrated to generate the water leakage sound of the pipeline; meanwhile, the flowing tap water can impact media (such as soil, sand, concrete and the like) around the pipeline to generate medium water leakage sound. The water leakage sound of the pipeline and the water leakage sound of the medium form the water leakage sound which is actually heard in the field.

The existing listening rod is often required to be inserted into the soil of soft soil, but the existing listening rod is in a thin rod shape, is inconvenient to hold, and in the process of repeated insertion, the outer wall of the rod body is attached with soil, and when a large amount of bacteria or other polluting impurities are contained in the soil, the health of a human body is harmed.
