Abstract
Description
technical field
[0001] The invention relates to a leakage detection device for a non-excavation construction arc pipeline. Background technique
[0002] Trenchless construction refers to the construction technology of laying, replacing and repairing various underground pipelines under the condition of excavating a very small part of the ground surface by using various rock and soil drilling equipment and technical means, such as guided and positioned drilling, etc. It will not hinder traffic, will not damage green land and vegetation, and solves the interference of traditional excavation construction on residents' lives. Arc pipes are an important part of trenchless construction and are usually used to transport liquids, gases, etc.
[0003] Since the arc pipeline is buried directly below the ground surface, it is necessary to perform leak detection on the arc pipeline before construction and installation to improve the safety of the arc pipeline after installation. However...
