Detecting vehicle for tunnel

Abstract

The invention discloses a detecting vehicle for a tunnel, which comprises the detecting vehicle and a propelling system, a braking system, an image pick-up system, an image pick-up system support device, a travel measuring system, an infrared triggering device, a computer and a power supply system which are mounted on the detecting vehicle. The propelling system supplies power for the detecting vehicle and controls the detecting vehicle to run; the braking system supplies a braking force for the detecting vehicle and controls the detecting vehicle to stop running; the image pick-up system support device is used for mounting and supporting the image pick-up system; the appearance condition of the tunnel is obtained through taking photos by using the image pick-up system; the travel measuring system is used for measuring a traveling distance of the detecting vehicle; the infrared triggering device is used for triggering the computer and the image pick-up system to work; the computer receives the information acquired by the travel measuring system and the image pick-up system and stores the received information; and the power supply system supplies electric power for the detecting vehicle. Compared with the traditional manual detection, the detecting vehicle is timesaving and laborsaving and has high reliability; and in addition, detecting results before and after can be contrastively analyzed.

Description

technical field [0001] The invention relates to a detection vehicle used in subway tunnels, belonging to the field of civil engineering. Background technique [0002] The first line of the Shanghai Metro was officially put into operation on April 10, 1995, 15 years ago. At present, there are 11 lines in use, of which, except Line 3, which is a light rail and some suburban lines, the remaining sections are all underground sections. [0003] The construction of the underground section of the Shanghai Metro adopts the shield method, and the lining structure of the subway tunnel in the underground section is assembled by pre-installed reinforced concrete segments. Various reasons, such as abnormalities in the fragile parts of the tunnel structure, and as time increases, cracks or water leakage will form on the surface of the tunnel lining structure. [0004] In view of the structural diseases in Shanghai subway tunnels, it is usually necessary to arrange for trained profession...

Problems solved by technology

[0005] However, due to manual errors and omissions, the current method of identifying the apparent disease phenomenon of the subway tunnel structure with the naked eye cannot guarantee that there will be no omissions, and it is possible to discover and record various existing tunnel structure diseases.

Moreover, the structural maintenance of Shanghai’s subway tunnels can only be carried out at night when the operation is closed. For a large number of tunnel inspections, it takes a lot of time, manpower and material resources to manually complete the structural inspections of all underground subway tunnels in Shanghai.
