Example Embodiment

[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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] The supporting structure for seepage prevention and reinforcement of the soft rock slope of the present invention, such as figure 1 As shown, it includes a modified epoxy protective layer 1 sprayed on the surface of a soft rock slope. A plurality of anchor holes are evenly arranged on the slope surface. There are cracks 31 around the hole walls of the anchor holes, and the cracks 31 are filled with silicone modified Resin prevents the rock mass from collapsing...

Abstract

The invention discloses an impermeable reinforcing supporting structure for a soft rock slope and a reinforcing method of the impermeable reinforcing supporting structure. The impermeable reinforcingsupporting structure comprises a modified epoxy resin protection layer sprayed on the surface of the soft rock slope, a plurality of anchoring holes are evenly formed in the modified epoxy resin protection layer, cracks are distributed at the periphery of the hole wall of the anchoring hole, an organosilicone modified resin is filled in the crack; a protection layer is arranged on the modified epoxy resin protection layer, a catchwater is arranged at the top part of the soft rock slope, a drainage ditch is arranged at the bottom part of the soft rock slope, a plurality of capillary drain pipesare evenly arranged on the slope surface of the soft rock slope, the outer end of the capillary drain pipe extends outwards of the protection layer, and the outer end of the capillary drain pipe inclines downwards. The soft rock slope is protected, the construction disturbance on the surface layer of the slope and a crack rock mass at the periphery of the hole wall of the anchoring hole are effectively inhibited, the strength degradation is effectively inhibited after the slope is wet, the protection strength and the stability of the slope are improved, and the problems existing in the priorart are solved.

Description

technical field [0001] The invention belongs to the technical field of slope engineering, and more particularly relates to a support structure for anti-seepage reinforcement of a soft rock slope and a reinforcement method thereof. 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 ...
