Arched tunnel side wall flatness detection device

Abstract

The invention relates to the technical field of detection of highway engineering field construction, and discloses an arched tunnel side wall flatness detection device which comprises a vehicle body,a vehicle seat, a motor, a ruler, a section tester, a section printer and a level bubble, the vehicle body is movably mounted at the top of the vehicle seat, and the motor is mounted at the bottom ofthe vehicle seat. Through the arched tunnel side wall flatness detection device, a lifting mechanism is arranged between vehicle bodies, the vehicle body can ascend and descend at will, and the flatness of the side wall of a tunnel can be detected more conveniently; compared with the prior art, the device has the advantages that auxiliary tools are not needed, and matching difficulty of detectionis reduced; through arrangement of telescopic rods, suction cups, fixing rods and adjusting knobs, the telescopic rods are moved, the suction cups at the top ends of the two telescopic rods are attracted to the side wall of the tunnel, the ruler is moved and adjusted through the fixing rods and the adjusting knobs, and the problem that the ruler cannot be directly close to the side wall for detection due to tunnel soil accumulation is solved.

Description

technical field [0001] The invention relates to the technical field of detection of highway engineering site construction, in particular to a detection device for the flatness of the side wall of an arched tunnel. Background technique [0002] At present, my country has become the world's largest country in the scale and speed of tunnel and underground engineering construction. Since 2011, the average annual net increase of road tunnels has exceeded 1,000 kilometers. Tunnel construction monitoring and quality inspection are important control methods to ensure tunnel quality and safety. The prior art discloses a large tunnel flatness detection device (201720433936.2), which includes three parts: leveling system, support system, data acquisition and drawing system. Flatness map of the range. [0003] However, the existing technology has the following defects. There are often a large amount of tunnel soil in the tunnel. The side wall of the tunnel cannot be detected using th...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an arched tunnel side wall smoothness detection device, which has the advantages of not needing auxiliary tools, reducing the coordination difficulty of detection and improving the accuracy of detection, etc. It is difficult to achieve good cooperation to detect the side wall of the tunnel, which increases the difficulty of detection.
