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 a soft rock side slope soil ecological protection method. The soft rock side slope soil ecological protection method comprises the steps that soft rock is sprayed with a layerof curing agent, the curing agent penetrates into the soft rock to prevent the soft rock from weathering and disintegration, then slope surface cleaning and leveling are carried out, the anchor rod positions are determined according to a design drawing, and drilling construction and installation of anchor rods are carried out; iron gauzes are laid along the slope surface according to the trend ofthe slope surface, the iron gauzes are tightened, and the anchor rods are used for fixing after flat and smooth laying is carried out; a planting matrix and the curing agent are evenly mixed to be sprayed to the slope surface at three times, the first-time spraying thickness is 2 to 3 cm, and the total thickness obtained by spraying three times is 11 to 14 cm, and after spraying of the matrix is completed, nutrient mud mixed with grass seeds is evenly sprayed onto the matrix by a hydraulic hydroseeder; the anti-scour ability and the wind erosion resistance of a soil body are improved; and theadopted curing agent can interact with soil so that the growth and development of vegetation are facilitated, and replaced soil spraying can be carried out for ecological protection on the basis of soft rock slope solidifying.

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...
