Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] Such as Figure 1 to Figure 5 As shown, an underground cavity peeping device based on 3D scanning and 3D printing includes a 3D probe 1. The 3D probe 1 adopts white light surface scanning technology, and the scanning accuracy is within 0.1 mm. Compared with the laser 3D scanner, the accuracy is higher, and the details The features are more complete, and the scanning speed is 3-4 times that of similar products. It is simple and fast. It can flexibly switch between turntable scanning and free scanning modes, adapting to 3D scanning of different sizes. Through data splicing, large-scale 3D scanning can be realized. White light scanning phase Compared with laser scanning, it is safer and will not cause accidental damage to human eyes. It is lightweight and portable. After scanning, it can directly output STL data for 3D printing and seamless connection; the three-dimensi...

Abstract

Disclosed is an underground cavity peeping device and method based on three-dimensional scanning and 3D printing. By using the underground cavity peeping device, the technical problem that conventional peeping devices cannot acquire cavity information in an omnibearing manner. The underground cavity peeping device comprises a three-dimensional probe and a connecting rod, and further comprises a 3D data collector, 3D printing equipment and a supporting frame, the three-dimensional probe is arranged on a first rotating structure which is fixed at one end of the connecting rod, the other end of the connecting rod is fixedly connected with the supporting frame through a second rotating structure, the three-dimensional probe is electrically connected with the 3D data collector through a data line, and the 3D data collector is electrically connected with the 3D printing equipment. The underground cavity peeping device is simple in structure, convenient for disassembly and assembly and convenient to operate, can detect position and surrounding rock breakage condition of an underground cavity in an omnibearing manner, can quickly re-demonstrate distribution range and spatial form characteristic of an actual cavity through 3D printing and has important practical value in reasonably determining underground cavity treatment methods of underground engineering of at present stage.

Description

technical field [0001] The invention relates to the technical field of underground cavity peeping, in particular to an underground cavity peeping device and method based on three-dimensional scanning and 3D printing. Background technique [0002] With the rapid development of my country's economic construction, the importance of underground resource mining and underground space development and utilization has become increasingly prominent. Man-made geotechnical activities or natural geological movements have produced a series of cavities below the surface. The existence of underground cavities makes underground resources safe. Mining and the development and utilization of underground space are facing serious safety problems. As the underground geotechnical engineering goes deep, underground cavities are prone to major accidents such as surface collapse, roof caving, rock layer movement, and impact mine pressure under strong ground pressure. Underground cavities have become an...
