Embodiment 1

[0021] A slope protection construction method for a gentle slope of a reservoir, comprising the following steps:

[0022] (1) Slope shaping, remove loose gravel and large stones with a particle size of more than 10cm, and dig multiple intersecting trenches in the vertical and horizontal directions of the slope, and the depth of the excavated trenches is 10-25cm , with a width of 5-10cm, forming a grid; the area of ​​each grid cell is 50-100cm 2 .

[0023] (2) Lay steel bars in the trench, then cast concrete, and cure for 13 days to form a concrete grid, the concrete grid is 10-15cm higher than the slope; the concrete is mainly made of the following raw materials: ordinary aluminum sulfate cement, fine aggregate , slaked lime, kaolin and calcium lignosulfonate. The mass ratio of mixing is 70:20:15:10:3.

[0024] (3) Seeding, the modified soil mixed with grass seeds is sprayed in the grid of the side slope, and the thickness of the sprayed modified soil is 5-10cm. For the gr...

Abstract

The invention discloses a slope protection construction method of a reservoir gentle slope. The method comprises following steps: firstly, the slope is shaped, multiple crossed grooves are dug in the slope longitudinally and transversely, and grids are formed; secondly, reinforcing steel bars are laid in the grooves, concrete is poured, curing is carried out for 10 to 15 days, and concrete grids are formed; thirdly, seeding is carried out, modified soil mixed with grass seeds is sprayed to the grids of the slope, and is pressed and flattened, non-woven fabric is laid, and construction and seeding are finished, wherein the modified soil in the third step is made of raw materials including, by weight part, 9 parts to 13 parts of bentonite, 5 parts to 12 parts of kaolin, 2 parts to 7 parts of corn starch, 1 part to 3 parts of mesh polypropylene-fiber, 3 parts to 9 parts of coal ash, 1 part to 5 parts of fertilizer, 7 parts to 15 parts of clay and 9 parts to 13 parts of fine silica powder. According to the slope protection construction method of the reservoir gentle slope, the modified soil is added during construction, the surface layer soil stability can be improved, soil losses are small, and the good ecological protection effect can be obtained.

Description

technical field [0001] The invention relates to the field of slope protection, in particular to a slope protection construction method for a gentle slope of a reservoir. Background technique [0002] During the construction of infrastructure such as roads, railways, water conservancy, and mines, the destruction of the original landform and vegetation is inevitable. Spoils, rocks, and excavations will leave a large number of exposed slopes in a harmonious natural environment. The slope ecology Protection can conserve water sources, reduce soil erosion, and can effectively purify the air, protect the ecology, beautify the environment, and has good ecological benefits. [0003] Slope protection technology mainly includes plant protection and engineering protection. Plant protection generally adopts artificial grass laying, grass planting and planting shrubs (trees), etc., and is mostly used on soil slopes with low slope height, gentle slope, and suitable for plant growth, but ...
