Problems solved by technology

[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, the existing leak detection is generally carried out manually or by leak detection equipment. , less efficient

Abstract

The invention discloses a leakage detecting device for non-excavation construction arc pipes. The leakage detecting device comprises a substrate, a bottom plate, leakage detecting mechanisms, a waterstorage tank and a hydraulic oil tank; the at least three leakage detecting mechanisms are arranged above the substrate at equal intervals, two transverse beams are arranged on the two sides of the leakage detecting mechanisms in parallel, the leakage detecting mechanisms are movably connected between the two transverse beams through second screws and guiding rods, the ends of the second screws are provided with second motors, the two ends of the transverse beams are connected with the substrate through first screws and second stand columns, first motors are arranged at the bottom ends of thefirst screws, and the leakage detecting mechanisms are connected with the water storage tank and the hydraulic oil tank through water conveying pipes and oil conveying pipes. The leakage detecting device is simple in structure and high in practicability, leakage detection processing of the arc pipes with different pipe diameter modes and sizes can be achieved, rapid clamping positioning of the arcpipes can be achieved, the leakage detection efficiency on the arc pipes is greatly improved, and the working range of the leakage detecting device is enlarged.

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...
