Embodiment

[0053] The measuring device of the present invention is used to conduct a field test in the tunnel between Hailun Road and Linping Road of Shanghai Metro Line 4. The specific test process is as follows: select the section to be measured and fix the mobile measuring mechanism; use a tripod 10 to fix the camera 9 at an appropriate position, and use a shutter cable to take pictures to prevent accidental contact with the camera 9; turn on the laser and adjust the angle so that the arc profile surface emitted As vertical as possible to the longitudinal direction of the tunnel; turn on the laser range finder 4, and ensure that the ranging spot moves on the contour line during the rotation of the laser range finder 4 through three-axis adjustment; the laser range finder 4 rotates to the zero-degree initial position, That is, the starting point of the contour of the inner wall of the tunnel; control the laser rangefinder 4 to stop and take an image every time it rotates 10°, rotate 250...

Abstract

The invention relates to a tunnel section measurement device and a measurement method thereof. The measurement device comprises a measurement mechanism and a shooting mechanism, wherein the measurement mechanism comprises a moving component, as well as a rotating component, ranging devices, a transmission device, a control device and a power supply device which are arranged on the moving component; the rotating component comprises a displacement rotary table arranged on the measurement mechanism and a rotating shaft controlled by the displacement rotary table; the end part of the rotating shaft is provided with a mounting seat and extends out of the measurement mechanism; a plurality of ranging devices are arranged on the mounting seat according to a set distribution state, and can generate ranging light spots during ranging; the transmission device is used for generating arc profile light rays on the inner wall of a tunnel; and the shooting mechanism comprises a tripod and a camera arranged on the tripod, and is arranged at a certain distance to the measurement mechanism. Compared with the prior art, the tunnel section measurement device has the characteristics of relatively highprecision, relatively high speed, low cost, convenience in operation and the like, and can meet the requirement of quickly detecting a tunnel under the condition of ensuring certain precision.

Description

technical field [0001] The invention relates to the field of structure detection, in particular to a tunnel section measuring device and a measuring method thereof. Background technique [0002] With the rapid development of tunnel construction in China, a large number of tunnels have been built and put into operation. As the service time of the tunnel increases, the structure will inevitably suffer from deformation, cracks, water leakage and other diseases, which not only affect the normal use of the structure, but also seriously endanger the safety of the structure. Accurate and timely tunnel detection can effectively find the weaker areas in the tunnel, so as to carry out targeted reinforcement and repair, which is of great significance to ensure the safe operation of the tunnel. [0003] Section deformation is an important content in tunnel inspection. Traditional detection methods include manual visual inspection, cross-section convergence meter method, total station ...
