High slope rock mass reinforcement construction method

Abstract

The application belongs to the technical field of slope protection, and particularly relates to a high slope rock mass reinforcing construction method, which comprises the following steps: exploring the rock stratum on the surface of a slope body, and cleaning the rock that is about to fall off; pouring concrete at the bottom of the slope body to form a strip-shaped lower concrete platform, and pouring concrete at the top of the slope body to form a strip-shaped upper concrete platform. The application uses a steel plate as a supporting point, and the supporting point can be attached to the surface of the rock stratum by filling in concrete, and the rock stratum is supported and blocked by the solidified concrete, so that the rock mass can be reinforced. Since the supporting point does not contact the rock stratum on the surface of the slope body, the rock mass that is prone to falling off can be effectively supported with high strength, the falling rock can be buffered and blocked, and rainwater can be drained, so that the erosion of the rock stratum by rainwater is reduced, and the stability of the rock stratum is improved.

Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of slope protection, and particularly relates to a high-slope rock mass reinforcing construction method. BACKGROUND

[0002] Since the slope is prone to landslides, collapses, rolling and falling stones and the like, the road, pedestrians and buildings on the side of the slope bottom have great safety hazards, so the slope around the road and buildings needs to be protected to improve the safety of the slope and reduce the possibility of safety accidents.

[0003] At present, for the forward slope, the bonding force between the rock stratum and the slope body is weak, and the rock stratum is prone to sliding, but since the high slope is high in height and large in inclination angle, the rock stratum has many protruding points, so when reinforcing and protecting the high slope, the commonly used method is to protect the slope by means of the protection net and anchoring, and to fill the gaps between the rock strata by means of grouting to achieve the reinforcing purpose, but although the protection net can prevent falling stones to a certain extent, the reinforcing effect of the rock stratum is not greatly improved, and although the grouting has good reinforcing effect, the design of the grouting points and holes on the high slope is very inconvenient, and the grouting effect cannot be well guaranteed, resulting in poor reinforcing effect of the high-slope rock mass, and therefore, the high-slope rock mass reinforcing construction method is proposed to solve the above problems.
