Abstract

The invention discloses a device for comprehensively and rapidly detecting the structure damage of a running metro tunnel. The device comprises a track walking platform, an acquisition center and a structured light source, wherein the track walking platform comprises a front shaft and a rear shaft, which are arranged in parallel on a running track of a metro train; the front and rear shafts are connected into a I-shaped frame through a center sill; the structured light source is arranged on the front shaft; an upright post perpendicular to the center sill is arranged on the center sill; the acquisition center and an operating platform are arranged at the top end of the upright post; a pushing handle is arranged on the rear shaft. According to the device, the structure damage detection speed and data processing speed of the running metro tunnel can be greatly increased, the problems of low manual detection efficiency and long information feedback cycle are solved, a novel detection technology is provided for the detection of the structure damage of the metro tunnel, and the operation and maintenance decision making speed and the high safety of a metro structure are more effectively ensured.

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 ...
