Problems solved by technology
[0006] The purpose of the present invention is to provide an intelligent reinforcement device and method for micro-damage thin roofs of grottoes in ancient cultural relics ruins. When reinforcing the suspended and thin layered roofs in grottoes, the disturbance to the rock mass itself is relatively large, and there are no traces of reinforcement on the surface of the rock mass. The problem that cannot be eliminated and cannot meet the reinforcement requirements for cultural relics on the thin roof of the grottoes

The invention provides a device and method for intelligently strengthening micro-damage of a thin roof of an ancient cultural historic site grotto. The device includes an anchoring system, a support system, and a monitoring system; the anchoring system is arranged above the roof and used for anchoring the roof; the support system is arranged on surrounding rocks and used for supporting the anchoring system, and the force of the anchoring system is transmitted to a stratum where the surrounding rocks are located through the support system; and the monitoring system is used for collecting information data on the stress conditions of the anchoring system and the support system and determining the stress condition of a strengthening device monitored data. The method includes the steps that thegeological background of the stratum of the surrounding rocks is investigated, the position of a backing plate is confirmed and fixed according to the mechanical characteristics of the surrounding rocks; the support system is mounted, and the anchoring system is mounted; and the monitoring system is mounted. The strengthening device can intervene in advance through the monitored data to prevent the destruction of cultural relics, the damage to the cultural relics is small, the economical and efficient effects are achieved, and promotability is high.
Description
technical field [0001] The invention belongs to the technical field of roof reinforcement, and in particular relates to an intelligent reinforcement device and method for micro-damage thin roof of grottoes in ancient cultural relics sites. Background technique [0002] The roof reinforcement technology is mainly a mechanical measure taken against the stress relaxation, deformation and other instability phenomena induced by the change of the mechanical state of the top of the structure. Since the early 1950s, many cultural relics protection projects in my country have used reinforcement technology for support. Because of the flexibility of design and the characteristics of keeping the original state of cultural relics to the greatest extent, good support effects have been achieved. [0003] At present, anchoring technology is more commonly used in roof reinforcement technology. Its basic principle is to rely on the friction between the anchor body and the surrounding rock and...
