Borrowed soil spraying and seeding base material and road side slope ecological protection constructing method

Abstract

The invention relates to a borrowed soil spraying and seeding base material and a road side slope ecological protection constructing method. The borrowed soil spraying and seeding base material comprises a slope face base material and a plant-growing base material. The slope face base material comprises water and the following constituents of, by weight, 100 parts of planting soil, 90-110 parts of plant fiber, 1.0-1.5 parts of papermaking black liquid concentrated modified fluid, and 2.0-4.0 parts of organic fertilizer; and the plant-growing base material comprises water, plant seeds and the following constituents of, by weight, 50 parts of planting soil, 50 parts of peat soil, 45-55 parts of plant fiber, 0.5-0.8 part of papermaking black liquid concentrated modified fluid, and 1.0-2.0 parts of organic fertilizer. The borrowed soil spreading and seeding base material has the suitable granular structure, porosity and pH value and long-lasting water keeping and holding ability, suitable and stable environment and fertilizing effects are provided for growing of side slope plants, and slope face attachment is firm, the loss rate is low, hardening does not occur after long term use, and the borrowed soil is suitable for ecological protecting of the road side slope stone or hard soil slope face.

Description

technical field [0001] The invention belongs to the technical field of road slope ecological protection, and in particular relates to a soil spraying substrate for road slope ecological protection, and also relates to a road slope ecological protection method using the foreign soil spraying substrate Construction method. Background technique [0002] In recent years, my country's infrastructure construction is in full swing, especially the road construction has achieved world-renowned achievements. However, in the process of highway construction, considering factors such as route site selection, economic benefits, and social benefits, most road sections often require high filling and deep excavation construction, which disturbs the soil structure, destroys vegetation, and large-scale mountain quarrying , borrowing soil, resulting in exposed soil or rocks on the road slope and a large amount of waste soil and slag accumulation, causing serious damage to the ecological enviro...

Problems solved by technology

[0005] The most important part of guest soil spraying technology is the spraying substrate, which consists of soil, organic matter, fertilizer, water retaining agent, binder, water and plant seeds, and will also add improvers, pH regulators, etc. as needed, but Ordinary Portland cement is usually used as the base material of the existing guest soil spraying. Although it can improve the bonding force between the base material and the slope surface, the cement will increase the alkalinity of the base material, and the pH value is too high, resulting in burning seedlings. root phenomenon, which is not conducive to the growth of plants; existing water-retaining agents, soil improvers (such as pellets) and fertilizers usually use chemical reagents, which are not only costly, but are easy to lose with rainwater, and large-scale and long-term use will also Causes compaction of the base material after spraying, and does not provide good basic conditions for vegetation growth on barren bare rock or hard soil surfaces
