Embodiment 1~5

[0050] According to the ratio of raw materials in Table 1 and Table 2, the spraying anti-impact agents of Examples 1 to 5 were formed, and the rest of the conditions were the same.

specific Embodiment

[0067] Example 3 was used to provide the spraying anti-shock agent, and in October 2019 in Dalubian Town, Lianzhou, Guangdong, the spraying anti-shock agent was used to carry out a vegetation restoration test on the slope of the high-speed road section.

[0068] geographical environment

[0069] Lianzhou City is located in the northwest of Guangdong Province, on the upper reaches of the Xiaobei River. It is adjacent to Yangshan County in the southeast, Nan County in the southwest, Lanshan County and Jianghua County in Hunan Province in the northwest, Linwu County in Hunan Province in the north, and Yizhang County in Hunan Province in the northeast. Historically, Lianzhou was the junction of Guangdong, Hunan, and Guangxi provinces, and also the main thoroughfare from the Central Plains to southern Guangdong. The geographical coordinates of Lianzhou City are from 24°37′N to 25°12′N in north latitude and from 112°47′E to 112°07′E in east longitude. The total area is 2663.33 squ...

Abstract

The invention provides a slope ecological restoration spray-seeding anti-impact agent. The slope ecological restoration spray-seeding anti-impact agent is prepared from the following components in parts by weight: 40 to 90 parts of low-alkalinity sulfoaluminosilicate cement, 0.3 to 2 parts of organic gel, 0.4 to 4 parts of cellulose and 0.3 to 5 parts of a pH regulator, wherein the pH regulator is ammonium salt and organic acid, and the mass ratio of ammonium salt to the organic acid is (1:1)-(5:1), the organic gel is polyvinyl alcohol (PVA) and polyacrylic acid (PAA), and the mass ratio of the polyvinyl alcohol (PVA) to the polyacrylic acid (PAA) is (1:1)-(8:2). After 5%-20% of the composition is added into a spray-seeding matrix, the air permeability, cohesiveness, water-retaining property and rain wash resistance of soil can be improved, germination and growth of plants can be promoted, and the spray-seeding anti-impact agent is low in material price and environmentally friendly in performance.

Description

technical field [0001] The invention relates to the technical field of slope ecological restoration, in particular to a spraying anti-shock agent for slope ecological restoration and a construction method. Background technique [0002] With the economic development of our country, China has entered the peak period of infrastructure construction. In the construction of roads, railways, mines, water conservancy, housing construction and other projects, there are often a lot of excavation and disposal of earth and stone, and these earth and stone excavation, Abandonment exposes a large area of ​​ground and destroys vegetation, which not only destroys the original vegetation on the surface, but also causes serious soil erosion and ecological environment imbalance. In order to ensure the protection and stability of this type of slope, traditional engineering measures such as mortar masonry retaining wall, mortar plastering, and concrete are often used for slope protection. Althou...
