A detection system and detection method for subway tunnel segments

Abstract

The invention relates to a subway tunnel duct piece dislocation detecting system and detecting method. The detecting system comprises a vision detecting system and a mechanical alignment system. The vision detecting system comprises a lighting device, a kinect camera, an RFID ultrahigh frequency reader-writer, a posture sensor, a battery module and a tablet personal computer. The mechanical alignment system comprises a first servo direct current motor, a fixing end rod, a telescopic rod, a second servo direct current motor, a straight vertical rod, a detecting trolley body and strengthening ribs. The method comprises the steps that firstly, rough alignment is carried out on the mechanical alignment system; secondly, precise alignment is carried out on the tail end of the telescopic rod according to a depth graph collected by the vision detecting system; thirdly, in the detecting process, the posture sensor detects the inclination angle of the detecting trolley body, the tail end of the telescopic rod is corrected and adjusted in real time, and precise alignment is achieved; fourthly, the detected duct piece position where the dislocation height difference is large is the area where accidents are likely to happen, and positioning and recording are carried out through an RFID electronic tag on a duct piece. The detecting system and detecting method can detect a tunnel in an all-direction mode.

Description

technical field

[0001] The invention relates to the field of detection of subway tunnel segments, in particular to a detection system and a detection method for a subway tunnel segment dislocation. Background technique

[0002] During the shield construction process, a large number of wrong platforms are likely to occur at the turning points. Once the control measures are not discovered in time, the best time to discover potential safety hazards will be missed, and accidents such as tunnel water leakage and segment cracking will easily occur. As the damage continues to deepen, there may be a large amount of sediment influx, a large amount of water, etc. inside the segment, resulting in damage to the tunnel, and in severe cases, the tunnel collapses. Therefore, it is very important to detect the status of segments in time for tunnel safety.
