The invention relates to the technical field of roadbed cavities, and discloses an infrared ray-based roadbed cavity size measuring device, which comprises a roadbed and a cavity. According to the roadbed cavity size measuring device based on the infrared rays, the road surface is vertically drilled in the roadbed and the cavity to form a through hole, the diameter of the through hole is larger than the diameter of a first hydraulic rod and the diameter of a chain and smaller than the length of a placing plate, and it is guaranteed that the first hydraulic rod and the chain can penetrate through the through hole and the placing plate cannot fall off from the through hole; then, the size of the cavity can be measured through infrared rays emitted by an infrared emitter, so that detected data can be transmitted to a controller through wireless transmission, the controller is a host, a worker can start the measuring structure at a distance, and the data can be displayed on a display screen through data processing of the controller; and the effect of facilitating measurement is achieved, and the situation that personnel fall into a hole due to secondary collapse of the road surface, and serious accidents are caused is prevented.
Description
technical field [0001] The invention relates to the technical field of roadbed voids, in particular to an infrared-based device for measuring the dimensions of roadbed voids. Background technique [0002] The roadbed cavity is a common road disaster in the city. There are roughly two reasons. One is that in the soluble rock area, the development of underground karst caves leads to a cavity in the roadbed; , scour the soil around the pipeline, resulting in voids around the pipeline. If the subgrade cavity is not detected in time, when the scale develops to a certain extent, it will easily collapse under the action of the vehicle load on the upper part of the road, causing vehicles and personnel to fall into the cavity, causing serious accidents. [0003] The existing measurement tools all require staff to measure on the spot, which is prone to secondary collapse, causing the staff to fall into the cavity, causing serious accidents, and the existing measurement devices are tr...
