Embodiment 1

[0017] The ecological protection method of the soft rock slope soil of the present embodiment may further comprise the steps:

[0018] (1) Spray a layer of curing agent on the soft rock, let it penetrate into the soft rock to prevent the soft rock from weathering and disintegrating, then clean the slope, level it, determine the position of the bolt according to the design drawings, carry out drilling construction and install the bolt;

[0019] (2) Lay the barbed wire along the slope, tighten the net, and fix it with anchor rods after laying smooth;

[0020] (3) Mix the planting base material and curing agent evenly and then spray it on the slope surface three times. The thickness of the first spray is 2cm, and the total thickness of the three sprays is 11. After the substrate spraying is completed, use a hydraulic sprayer Spray the nutrient mud with grass seeds evenly on the substrate;

[0021] The curing agent raw material includes the following components in parts by weight...

Abstract

The invention discloses an ecological protection method for soft rock slope soil, which comprises spraying a layer of curing agent on the soft rock, allowing it to penetrate into the soft rock to prevent the soft rock from weathering and disintegrating, and then cleaning and leveling the slope surface, determined according to the design drawings At the position of the anchor, carry out drilling construction and install the anchor; lay the barbed wire along the slope along the slope, tighten the net, and fix it with an anchor after laying smooth; mix the planting substrate and curing agent evenly and spray it onto the slope three times On the surface, the thickness of the first spray is 2-3cm, and the total thickness of the three sprays is 11-14cm. After the substrate is sprayed, the nutrient mud with grass seeds is evenly sprayed on the substrate with a hydraulic sprayer; Improve the anti-scouring ability and anti-wind erosion ability of the soil. The curing agent used can interact with the soil, which is beneficial to the growth and development of vegetation. On the basis of curing soft rock slopes, guest soil spraying can be carried out for ecological protection. .

Description

technical field [0001] The invention relates to the field of slope protection. In particular, it relates to an ecological protection method for soft rock slope soil. Background technique [0002] Soft rock is a complex rock mechanical medium with significant plastic deformation in a specific environment. The basic mechanics theory and research methods of soft rock have been studied in depth. Over the years, the basic concepts of soft rock and soft rock engineering slope design And other theoretical issues, there has been no conclusion at home and abroad, which has brought a lot of inconvenience to soft rock engineering slopes. Soft rock engineering refers to rock mass engineering related to large plastic deformation engineering rock mass, such as soft rock tunnel engineering, soft rock slope engineering and so on. Regarding the definition of soft rock, there are many different interpretations, including descriptive definitions: (1) Soft rock formation refers to loose and w...
