Problems solved by technology

Among them, the hydration of Portland cement makes the substrate an alkaline environment, which is not conducive to plant growth and development; for emulsified asphalt, when the seeds come into contact with the asphalt, it will hinder the germination
[0005] (2) The strength of the base material is low
[0006] (3) High project cost
Therefore, the construction process is complicated, and the project cost is also increased.
[0007] The construction method of existing vegetation slope protection technology, as mentioned above, will hang the net before the construction, and cover after the construction, the method is complicated, labor-intensive and time-consuming, and the project cost is high, which is not easy to widely popularize and apply

Abstract

The invention relates to a gypsum soil plant building material and construction method thereof, wherein the gypsum soil plant building material comprises two constituents of base material and straw seeds, and the base material mainly comprises gypsum, soil, coal ash, plant fiber, fertilizer, water-loss reducer and water.

Description

technical field [0001] The invention belongs to a vegetation building material and a construction method, in particular to a vegetation building material and a construction method for lawn establishment, side slope protection and greening. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, people's requirements for the quality of living environment are getting higher and higher. Planting lawns is one of the important measures to beautify the environment, purify the air, and maintain water and soil. At present, the method of seed propagation is mainly used to build lawns. Although the cost is low, it is labor-intensive, affected by the weather, maintenance and management workload, etc., and requires soil suitable for the growth of grass seeds. [0003] During the construction of highways, railways, water conservancy and other infrastructure in China, due to a large amount of filling and e...
