Problems solved by technology

[0003] Anchor bolts are commonly used in geotechnical engineering support in the prior art. Due to the force deformation of the anchor bolts and the phenomenon of different degrees of thread withdrawal of the nuts, the anchoring force of the anchor bolts decreases, which seriously affects the active support of the anchor bolts. Bolt support has limited scope of application

Abstract

The invention relates to a reinforcing rock mass structure. The structure comprises a reinforcing structure and a reinforced body, wherein the reinforcing structure and the reinforced body are connected together through a connecting device; and transverse and vertical prestress formed through the connecting device ensures that: a working force generated by a main stress reinforcing member can be effectively converted into a reinforced force, the reinforcing structure and the reinforced body are forced to endure load together uniformly and deform together, surrounding rock stress is dispersed, and the original structure and compact degree of a surrounding rock can be protected. The structure not only can automatically adapt to deformation of the rock mass, but also can restrict further development of rock mass deformation, and improve the stress state of the rock mass on a side slope. The connecting device has simple structure and reasonable prestress distribution, and improves the reliability and safety of geotechnical engineering timbering. The structure has convenient construction and low cost, can be widely applied to constructions of mountain cities, traffic, water conservancy, mines, national defense and the like, and timbering of roadway, rock slope and foundation pit, surrounding rock reinforcement of tunnels, dangerous rock treatment and the like in facility engineering.

Description

technical field [0001] The invention belongs to the field of support in geotechnical engineering, and relates to a reinforced rock mass structure. Background technique [0002] With the increase of resource mining depth, the ground stress increases and the geological conditions deteriorate, which leads to the increasing difficulty of support in geotechnical engineering, such as the surrounding rock support of the deep roadway in the mine. The compressive shear stress of the rock exceeds its long-term strength. If the support is not timely and effective, the surrounding rock will soon crack and become unstable from the surface to the inside, and it will be difficult to bear the force of the rock wall and effectively prevent the displacement and shedding of the roadway wall rock. [0003] Anchor bolts are commonly used in geotechnical engineering support in the prior art. Due to the force deformation of the anchor bolts and the phenomenon of different degrees of thread withdra...
