Problems solved by technology

However, due to the large difference between the tunnel drainage system and the municipal drainage pipe, the diameter of the longitudinal drainage pipe and the circumferential drainage pipe of the tunnel is often small (usually only 50mm or 100mm), and there are often tees or turning parts , therefore, the inspection method of municipal drainage pipes often has the problem of low inspection efficiency

Abstract

The embodiment of the invention provides a method, device and system for checking a tunnel drainage pipeline. The method comprises the following steps that an infrared image of the outer surface of the area where the heated tunnel drainage pipeline is located is acquired, and according to the infrared image, the blockage condition of the tunnel drainage pipeline is determined. Therefore, accordingto the embodiment of the method, the tunnel drainage pipeline is heated, so that the areawhere the periphery of the tunnel drainage pipeline is located can also be heated, the area where a conductionpart in the tunnel drainage pipeline is located is speedy in temperature rise, so that the area where the tunnel drainage pipeline is located can be identified by utilizing the infrared image; andtheblockage condition in the tunnel drainage pipeline can be quickly determined, so that the checking efficiency is improved, and the checking cost isfurther reduced.

Description

technical field [0001] The present application relates to the technical field of tunnel inspection, in particular to a method, device and system for inspecting tunnel drainage pipes. Background technique [0002] The tunnel drainage system is an important part of tunnel construction, normal use of the tunnel and safe operation of the tunnel. [0003] In the tunnel operation stage, the more common problem is that the tunnel drainage system is prone to blockage. The source includes the intrusion of concrete and other debris during the construction stage, the accumulation of sediment and rock debris in the groundwater during the operation stage, and the precipitation and crystallization of the groundwater in karst areas. things etc. Once the drainage system of the tunnel is blocked, local water flow will be unsmooth, and the leakage of tunnel water will intensify and affect the normal operation and use of the tunnel. In severe cases, the water pressure on the tunnel lining str...
