An anti-seismic reinforcement device for rock mass cultural relics of grotto columns

Abstract

The invention proposes an anti-seismic reinforcement device for rock cultural relics of grotto columns, which belongs to the technical field of open-air large-scale stone cultural relic protection equipment. The device includes a column reinforcement system and an anti-seismic energy-absorbing system. The column reinforcement system covers On the outside of the protected column relics, the anti-seismic energy-absorbing system includes a first anti-seismic energy-absorbing column and a second anti-seismic energy-absorbing column, which are respectively arranged on both sides of the protected column cultural relics; the overall structural design of the present invention has good Stability, the cement mortar poured inside greatly improves the strength of the column rock mass, and at the same time fills the large cracks in the column body, and enhances the stability between the column rock mass and the upper cave body; the invention completely isolates rainwater, atmosphere and column rock mass The direct contact of the cultural relics fundamentally eliminates the formation conditions of weathering and prevents the secondary weathering of the pillar rock cultural relics; the invention avoids the destruction of the pillar rock cultural relics caused by the earthquake and the occurrence of personnel casualties to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of protection equipment for large-scale open-air rocky cultural relics, and in particular relates to an anti-seismic reinforcing device for column rock mass cultural relics in grottoes. Background technique [0002] As an immovable large-scale open-air cultural relic, the grotto column rock mass has been affected by various natural factors such as geological force and environmental factors for a long time. The surface of the column rock mass has weathering, large cracks and other diseases. A large number of seismic research data show that under the influence of seismic waves, there are cracks, alteration zones, joints, faults and other geological weak structural planes in the column rock mass that are prone to damage, and nearly 70% of the grottoes in my country are distributed in high-intensity areas and earthquake-prone areas Therefore, it is very important and meaningful to carry out the research on the pr...

AI Technical Summary

Problems solved by technology

However, for the pillar rock mass that has been weathered and has serious weathering diseases or large cracks, its supporting effect on the upper cave body is quite limited, and its own strength and stability have become problems. Therefore, the above-mentioned techniques have little effect and cannot be applied; And there is no design research on the anti-seismic and energy-absorbing aspects of large-scale open-air stone cultural relics
