Problems solved by technology

The main point of this technology lies in the selection of spraying base material, hanging net, and grass seed. The disadvantage is that this construction process also uses the form of hanging net to closely combine the base material with the slope surface, and it must be constructed before the rainy season to prevent rainwater from spreading The base material is washed away from the slope, and the workload of guest soil spraying is still relatively large. It is necessary to hang the net, and the cost is high. The problem of the base material's anti-rainwater erosion has not been effectively solved.

Embodiment 1

[0094] A slope greening protection method, comprising the following steps:

[0095](a) Cleaning: clean up the slope with an inclination angle of 30°, so that the construction slope is basically stable and meets the construction requirements;

[0096] (b) Preparation of spraying base material: mix soil, fertilizer, seeds, water, water retaining agent, adhesive and cement in a certain proportion to prepare a paste-like slurry with certain fluidity to form a spraying base material ;

[0097] Among them, based on the spraying base material, the mass percentage of the water-retaining agent is 5% (the spraying season is summer, sandy slope), the mass percentage of the adhesive is 4%, and the mass percentage of the cement is 5%. Content is 4%, and the mass percentage composition of fertilizer is 9%, and the consumption of water makes the water content rate of spraying base material 40%;

[0098] (c) Injection: placing the above-mentioned spraying substrate in the container, and tra...

Embodiment 2

[0102] A slope greening protection method, comprising the following steps:

[0103] (a) Cleaning: clean up the slope with an inclination angle of 30°, so that the construction slope is basically stable and meets the construction requirements;

[0104] (b) Preparation of spraying base material: mix soil, fertilizer, seeds, water, water retaining agent, adhesive and cement in a certain proportion to prepare a paste-like slurry with certain fluidity to form a spraying base material ;

[0105] Among them, based on the base material of spraying, the mass percentage of water-retaining agent is 3% (spraying season is spring, cohesive soil slope), the mass percentage of adhesive is 4%, and the mass percentage of cement is 100%. Fertilizer content is 3%, the mass percentage composition of fertilizer is 10%, and the consumption of water makes the water content rate of spraying base material 50%;

[0106] (c) Injection: placing the above-mentioned spraying substrate in the container, a...

Abstract

The invention belongs to the technical field of slope protection and particularly relates to a slope greening protection method. The slope greening protection method comprises the following steps that(1) a spraying and sowing substrate is prepared; (b) the spraying and sowing substrate is injected into a slope surface layer through implanting equipment, the injection depth is 5-20 cm, and a soillayer and / or sand layer replacement body is formed; (c) then maintenance is performed until seedling forming. According to the slope greening protection method, the construction technology can be simplified under the premise that the greening effect is ensured, the washing influences of rainfall to the spraying and sowing substrate and the slope are reduced, and the purpose of reducing greening cost is realized.

Description

technical field [0001] The invention belongs to the technical field of side slope protection, and in particular relates to a side slope greening protection method. Background technique [0002] There is a great development prospect for foreign soil spraying in the ecological restoration of engineering slopes, the management of mine geological environment and the environmental management of dump sites. Soil spraying greening is a new type of greening technology introduced from Japan to China in the late 1990s. After fully mixing grass seed fertilizer, water retaining agent, soil, organic matter, stabilizer and other mixtures, it is evenly sprayed to the desired area by a sprayer according to the designed thickness. Protected engineering slopes to achieve the purpose of landscape similar to natural greening. At present, the development of foreign soil spraying technology in China is mainly reflected in the diversification of spraying machinery and spraying substrate construct...
