An automatic detection system and method suitable for tunnel lining

Abstract

The invention provides an automatic detection system and method suitable for tunnel lining. The automatic detection system comprises segmented embedded guide rail units and a radar antenna coupled automatic scanning device, wherein each segmented embedded guide rail unit comprises multiple segmented guide rails and embedded brackets, each embedded bracket supports one segmented embedded guide rail, one end of each embedded bracket is pre-embedded in a position to be detected, and the multiple segmented guide rails are linearly arranged to form a track for the radar antenna coupled automatic scanning device to move. The radar antenna coupled automatic scanning device comprises a geological radar, elastic parts and a walking mechanism, wherein the walking mechanism is parallel to the operation direction of the geological radar, the elastic parts are arranged between the walking mechanism and a radar antenna, and the radar antenna is supported through the walking mechanism on the track consisting of the segmented embedded guide rail unit for lining quality detection.

Description

technical field [0001] The disclosure relates to a system and method suitable for automatic detection of tunnel lining. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] A tunnel is a channel dug out of an existing building or earth-stone structure, buried inside the ground, and is a form of human development and utilization of underground space. Tunnels are classified into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. [0004] At present, the construction method adopted by most tunnels in my country is the new Austrian method, which is to form a composite inner and outer two-layer lining to build the tunnel body, that is, to use shotcrete, anchor rods, steel mesh, steel supports, etc. as the outer support form. Called the primary flexible support. The initial support of the tunnel may have defects such as under...

AI Technical Summary

Problems solved by technology

[0006] First, the current tunnel lining inspection is almost not automatic or semi-automatic. The operator still needs to lift the ground radar antenna for a long time while standing on the trolley.

This method is inefficient, not only wastes a lot of time and resources, but also increases the fatigue of the operator for a long time, and this kind of high-altitude operation causes safety hazards

[0007] Second, because the support surface of the tunnel is rough and uneven, after the operator lifts the geological radar antenna for a long time, the lifting may be unstable and shake, causing the radar antenna to decouple from the support surface, and it is impossible to ensure that the radar is always attached to the support surface. On the protective surface, this reduces the accuracy of detection and fails to achieve the expected effect
