Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The invention provides a comprehensive and rapid detection device for operating subway tunnel structural diseases, such as figure 1 As shown, it includes a track walking platform 1, a collection center 2, a structured light source 3, and the track walking platform 1 includes a front axle 7 and a rear axle 8 parallel to each other placed on the running track of a subway train, and the front axle 7 and the rear axle 8 pass through the center Beams 9 are connected to form an "I"-shaped frame, and a structured light source 3 is arranged on the front axle 7. The structured light source 3 is an auxiliary light source in this equipment, mainly to provide an internal contour auxiliary line for easy detection on the inner surface of the detection tunnel. In the installation position, the distance from the structured light source 3 to the indust...

Abstract

The invention discloses a comprehensive rapid detection device for structural defects in subway tunnels, which includes a track walking platform, a collection center, a structural light source, and the track walking platform includes a front axle and a rear axle parallel to each other placed on the running track of a subway train. The front axle and the rear axle are connected through the middle beam to form an "I"-shaped frame. A structured light source is arranged on the front axle, and a vertical column is arranged on the middle beam. The top of the column is equipped with a collection center and an operating platform. It is provided with a pushing handle. The device can greatly speed up the inspection speed and data processing speed of subway tunnel structural defects, solve the problems of low efficiency of artificial price difference and long information feedback cycle, and provide new detection technology for the detection of subway tunnel structural defects, more effective It guarantees the decision-making speed of subway operation and maintenance and the safety of subway structure.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a comprehensive and rapid detection device for structural diseases of operating subway tunnels. Background technique [0002] At present, the domestic operating subway mileage has reached 1,500 kilometers, and domestic subway construction is in the ascendant, and a large number of subways will be put into operation in the near future. By 2020, the total mileage of urban rail transit in China is expected to reach about 6,100 kilometers. [0003] During the operation of the subway, apparent defects such as water leakage or cracks in the tunnel structure mainly made of concrete materials, as well as deformation of the tunnel section, are unavoidable disease phenomena, and the long-term development of the disease has irreversible effects on the safety of the tunnel. negative impact. Therefore, the maintenance of the tunnel structure in the subway operation is ...
