Description

Leakage listening rod

Technical Field

The utility model relates to an underground network management leak hunting device technical field, concretely relates to listen and leak 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.

Before carrying out the leak hunting to underground network management, need listen earlier to leak the pole and insert earth in, make the lower extreme of listening to leak the pole be close to the contact with the network management, insert and extract the in-process of listening to leak the pole, generally need the user to grip the body of rod with both hands, need grip the different positions of the body of rod under the different circumstances of the depth of insertion, if directly grip the body of rod, it is inconvenient to grip to still cause the damage to the hand easily.
