Description

Detection tools for underground pipeline emergency repair and excavation operations

Technical field

The invention relates to the technical field of emergency repair of underground pipelines, and in particular to a detection tool used for emergency repair and excavation operations of underground pipelines.

Background technique

With the rapid development of urban construction, a large number of underground pipelines such as gas pipelines are usually buried underground in the city. Therefore, emergency repair and excavation operations are very frequent due to various reasons. However, the distribution of various underground pipelines is intricate and complicated. During emergency repair excavation operations, it is necessary to prevent excavation tools from damaging the target pipeline and other pipelines. In the existing technology, excavation operations (exploration and then deep digging) are usually used for excavation. Traditional exploration operations generally use the following two methods. : 1. The excavator driver uses the bucket or the back of the bucket to push back and forth on the working surface to perform excavation operations. However, because the strength of the excavator is difficult to control, it is easy to dig through the target pipeline and other pipelines, and it is impossible to ensure that the target pipeline and Safety of other pipelines; 2. On-site workers use tools such as drills or hoes to carry out excavation operations by pushing back and forth on the working surface. However, due to the low excavation efficiency of tools such as drills or hoes, the workers' The labor intensity is high and the construction period is long.
