Problems solved by technology

However, these support methods do not take into account the infiltration of rainwater after slope excavation and the strength degradation caused by construction disturbance and cooling water infiltration into the rock mass around the hole wall during the bolt drilling process. Therefore, the existing support measures need to be further improved.

Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The supporting structure of the soft rock slope anti-seepage reinforcement of the present invention, such as figure 1 As shown, it includes a modified epoxy protection layer 1 sprayed on the surface of the soft rock slope, and a plurality of anchor holes are uniformly arranged on the slope surface. There are cracks 31 distributed around the walls of the anchor holes, and the cracks 31 are filled with organic silicon modified Resin, inhibits rock mass from disintegratin...

Abstract

The invention discloses a support structure for anti-seepage reinforcement of a soft rock slope and a reinforcement method thereof, comprising a modified epoxy protective layer sprayed on the surface of the soft rock slope, and a plurality of modified epoxy protective layers are evenly arranged on the modified epoxy protective layer Anchor hole, there are cracks distributed around the wall of the anchor hole, the cracks are filled with silicone modified resin; the modified epoxy protective layer is provided with a protective layer, and the top of the soft rock slope is equipped with a water intercepting ditch, and the soft rock slope Drainage ditches are arranged at the bottom of the slope, and a plurality of capillary drainage pipes are evenly arranged on the slope surface of the soft rock slope. The invention can protect the soft rock slope, effectively inhibit the surface layer of the slope and the cracked rock mass around the wall of the anchor hole from being disturbed by construction and strength degradation after encountering water, improve the protection strength and stability of the slope, and solve the problems in the prior art Existing problems.

Description

technical field [0001] The invention belongs to the technical field of slope engineering, and more particularly relates to a support structure and a method for seepage-proof reinforcement of soft rock slopes. Background technique [0002] With the in-depth development of mineral resources and the continuous development of slope engineering, the stability of soft rock slopes has become increasingly prominent. Due to the unique physical and chemical properties of soft rock, it is extremely sensitive to environmental factors such as temperature, humidity, stress, and groundwater, and it is easy to soften and disintegrate when exposed to water, resulting in slope instability. After the soft rock slope is excavated, there is no temporary support, and when signs of landslides and collapses are found, the method of setting up fixed piles and erecting steel pipe frames is used for support, which is time-consuming and laborious; in addition, after the soft rock slope is excavated, th...
