Problems solved by technology

The hanging net planting method has the characteristics of good governance effect, little impact on plant growth, and is conducive to ecological restoration, but the governance cost is relatively high
The management cost of flake covering is relatively low, and the treatment effect is good. However, in order to reduce the cost, large divisions are generally used, and there will be a certain amount of erosion, which will also have a certain impact on the growth of plants.

Abstract

The invention relates to a silt adhesive and a preparation method thereof. The silt adhesive is characterized by being prepared by mixing the raw materials including 1.0 to 10 percent of starch adhesive, 0.1 to 5 percent of polymer emulsion, 0.1 to 1 percent of plasticizer, 5 to 30 percent of clay, 0.01 to 0.5 percent of assistant and 55.5 to 93.97 percent of water. The silt adhesive has the characteristics of providing a micro environment suitable for plants to grow, along with excellent solidification effect, low cost and environmental protection.

Description

technical field [0001] The invention relates to a silt binder and a preparation method thereof. Background technique [0002] Silt is widely distributed as a type of soil structure, and it is also a soil structure that is often encountered in road and railway construction. Silt is characterized by loose structure, poor cohesion, and easy to be lost by rainwater. Barrenness is also a characteristic of silt structure, and poor silt is not conducive to the survival and growth of plants. If the road slope encounters a silt structure, if it is not effectively treated, water and soil erosion will occur during rainfall, causing slope instability, and even damage to the slope. The drainage system will be blocked, increasing the maintenance cost of roads and railways, and affecting The service life and driving safety of roads and railways. Therefore, the treatment of silt slopes has become an important task in the construction and maintenance of roads and railways. [0003] At pr...
