Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of subway tunnel construction segment water seepage detection, in particular to a subway tunnel construction segment water seepage detection device. BACKGROUND

[0002] The subway tunnel construction segment, namely the shield segment, is the main assembly component of shield construction, is the innermost barrier of the tunnel, and bears the action of resisting the earth pressure, the underground water pressure and some special loads. The shield segment is the permanent lining structure of the shield method tunnel, and the quality of the shield segment is directly related to the overall quality and safety of the tunnel and influences the waterproof performance and durability of the tunnel. In the tunnel underground engineering, the performance requirement of the tunnel inner wall waterproof is extremely high, and the main function of the tunnel construction segment is to support the tunnel and prevent water seepage. During the normal use of the tunnel, the water seepage of the tunnel construction segment needs to be detected at all times to avoid the occurrence of tunnel collapse accidents.

[0003] In view of this, the subway tunnel construction segment water seepage detection device disclosed in Chinese patent No. CN114509375B is provided. The transparent ink on the surface of the red detection belt is changed to transparent red and leaks out when it is wetted by water, so that the red detection belt shows obvious red, and the water leakage area is determined. The roller can roll on the inner wall of the segment, so that most areas of the inner wall of the segment can be detected, and safety hazards are avoided due to omission.

[0004] However, the above technical solution is in a moving state during the water seepage detection process, so that the color change of the test paper after losing moisture needs a certain time, and when the test paper changes color, the detection device has been displaced for a distance, which is not convenient for the staff to determine the specific position of the water seepage. Various equipment needs to be installed on the inner wall of the tunnel, and a certain protrusion may be generated in the installation equipment area. The ordinary detection device does not have a buffering function when rolling on the inner wall for detection, which is easy to cause damage to the equipment due to extrusion at different distances. Moreover, the detection paper is easy to wear out and cannot be used after a long time of use. The existing detection device is very troublesome to replace the test paper. Therefore, the subway tunnel construction segment water seepage detection device is proposed. UTILITY MODEL CONTENTS
