3D positioning device and method for formulating follow-up guide rail curved surface based on shape of engineering structure

Abstract

The invention provides a 3D positioning device and method for formulating a follow-up guide rail curved surface based on the shape of an engineering structure, and the device comprises a follow-up rail frame, a detection trolley, and a trolley drive mechanism, wherein the shape of the follow-up rail frame is matched with the geometric shape of a detected engineering structure. The detection trolley is disposed on the follow-up rail frame. The detection trolley walks on the follow-up rail frame through the trolley drive mechanism. The device is advantageous in that 1, there is no need of high-altitude work, so the device is safe and efficient; 2, the device can achieve the single-lane operation under the condition that the traffic is guaranteed to be smooth when the device is used for a full-automatic intelligent tunnel detection vehicle for the detection of a special project of a road; 3, the detection platform can automatically rise and fall to avoid obstacles; 4, the follow-up rail frame achieves the full-section data collection; 5, the device is provided with a multi-channel radars, achieves the full coverage through lateral and longitudinal measurement lines, and achieves the three-dimensional detection of the structure and surrounding rock; 6, the device can enable panoramic photographing and infrared imaging equipment to be extended, and achieves the intelligent recognition of cracks and water damages.

Description

technical field [0001] The invention belongs to the technical field of engineering detection, and in particular relates to a 3D positioning device and method for customizing the curved surface of a conformal guide rail based on the shape of an engineering structure. Background technique [0002] According to incomplete statistics, as of the end of 2015, there were 14,006 road tunnels in operation in mainland my country, with a total length of 12,684km. However, according to the latest research report, the national road tunnels have serious quality problems after completion due to lining quality problems. At the present stage, the main method adopted in my country for the quality inspection of the road tunnel lining under construction or in use is to use a hand-held ground-penetrating radar antenna close to the tunnel wall to detect the lining and integrity. Specifically, the method of lining inspection for tunnels under construction or in use is as follows: the staff stand ...

AI Technical Summary

Problems solved by technology

This detection method mainly has the following problems: For relatively long tunnels, only one tunnel survey line or one tunnel longitudinal section can be detected at a time, and it takes a lot of time to complete the full-section measurement, and the efficiency is very low; Detection at high places has a greater potential safety hazard
