Problems solved by technology

[0005] For the detection of the convergence deformation of the tunnel section, there are currently several methods including manual section measurement, 3D laser scanning and tunnel inspection trolley. Manual detection is not only low in accuracy but also takes a long time. The price is too expensive, and the measured data cannot be displayed in real time. The tunnel inspection car currently uses the foreign Amberg GRP5000 car. This car is not only expensive, but also mainly detects cracks and water seepage inside the tunnel section. , but cannot detect the deformation of the tunnel section

Abstract

The invention relates to a mobile device for detecting tunnel section deformation. The device comprises a mobile module, an information collecting module and an information processing module, wherein the mobile module allows the device to move in a tunnel; the information collecting module is mounted on the mobile module during use and used for collecting the shape information of a tunnel section and the mileage positioning information of the mobile module; the information processing module is mounted on the mobile module during use, connected with the information collecting module and used for judging whether the tunnel section has deformation or not and a deformation position according to the collecting result of the information collecting module. Compared with the prior art, the device is accurate in deformation detection, small in detection error, convenient to mount and transport, capable of saving cost, and the like.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a movable detection device for deformation of tunnel section. Background technique [0002] At present, my country's urban rail transit is developing rapidly, and more than a dozen cities have opened subways. The subway has become an important way for citizens to travel, and the responsibility for ensuring the safety of subway operation is heavy. [0003] The safety problems during shield tunnel construction and subway operation are mainly manifested in the following aspects: the soft soil layer under the tunnel softens under the long-term vibration load and causes settlement; the construction activities near the tunnel cause tunnel deformation; the underlying soil layer of the interval tunnel Water and soil erosion causes destructive longitudinal deformation; when the tunnel passes through areas with different soil conditions, the difference in soil physical properties...
