Embodiment 1

[0024] A porous concrete slope protection method combined with grass and vines, specifically comprising the following steps:

[0025] 1) Add 270 parts of cement and 30 parts of silica fume, a mineral admixture, into the concrete mixer and mix well, then add 64.8 parts of water and 3 parts of water reducing agent and mix for 90 seconds, then put in 1760 parts of coarse aggregate and 88 parts of fine aggregate 16.2 parts of water, 0.27 parts of thickener and mix for 120s;

[0026] 2) Level the soil base of the side slope of the road, and then lay a sand layer of about 5cm; the formwork is made of wooden formwork, processed on site, the upper end is fixed with wooden piles, and the lower end is pushed with heavy stones, and the formwork is reinforced to ensure that it is vibrated during pouring. Not out of shape afterward. When filling the mixture, first fill it to half of the mold, tamp it with a tamping stick, then continue to fill it up and vibrate it, the time is controlled ...

Embodiment 2

[0030] 1) Add 270 parts of cement and 30 parts of silica fume as a mineral admixture into the concrete mixer and mix well, then add 64.8 parts of water and 3.2 parts of water reducing agent and mix for 90 seconds, then put in 1760 parts of coarse aggregate and 88 parts of fine aggregate 16.2 parts of water, 0.27 parts of thickener and mix for 120s;

[0031]2) Level the soil base of the side slope of the road, and then lay a sand layer of about 5cm; the formwork is made of wooden formwork, processed on site, the upper end is fixed with wooden piles, and the lower end is pushed with heavy stones. Not out of shape. When filling the mixture, first fill it to half of the mold, tamp it with a tamping stick, then continue to fill it up and vibrate it, the time is controlled at about 45s, and the test piece after the vibration is scraped and formed with a spatula;

[0032] 3) Curing: Sprinkle water 1-2 times after each construction period after the initial setting, and cover it with ...

Embodiment 3

[0035] 1) Add 270 parts of cement and 30 parts of silica fume, a mineral admixture, into the concrete mixer and mix well, then add 64.8 parts of water and 3.5 parts of water reducer and mix for 90 seconds, then put in 1760 parts of coarse aggregate and 88 parts of fine aggregate 16.2 parts of water, 0.27 parts of thickener and mix for 120s;

[0036] 2) The soil base of the side slope of the level road. If it is a rocky slope, clean up the gravel on the surface of the slope, and chisel the surface to facilitate the combination of concrete and the surface of the slope. Then lay a sand layer of about 5cm; the formwork is made of wooden formwork, processed on site, the upper end is fixed with wooden piles, and the lower end is pushed up with heavy stones, and the formwork is reinforced to ensure that it will not lose its shape after pouring and vibration. When filling the mixture, first fill it to half of the mold, tamp it with a tamping stick, then continue to fill it up and vib...

Abstract

The invention relates to a slope protecting method combining multi-hole concrete and grass vines. According to the method, at first, the multi-hole concrete is built on a soil texture or rock textureslope, then grass seeds and vine plants are sown on the slope face and the slope bottom correspondingly, during the earlier stage, the grass seeds grow fast and provide greening, during the later stage, vines climb the multi-hole concrete and grow to cover the slope face, and the functions of fixing water and soil and adjusting local water distribution are achieved. The method fully utilizes the characteristics that the survival rate of the vines is high, the requirement for soil texture is low, the vines are cultivated easily, and the grass seeds sprout and grow fast but not lasting, vine airroots constructed and conversed well are planted in holes of the concrete, the loosening risk of coarse aggregate is reduced, and the slope protecting method has great social benefits and environment-friendly benefits and is worthy of being applied and popularized.

Description

technical field [0001] The invention relates to the technical field of landscaping engineering, in particular to a slope protection method combining porous concrete with grass and vines. Background technique [0002] The ecological slope protection method of porous grass planting concrete has an ecologically efficient slope protection effect. It is widely used in Japan and the United States. Seasonal growth is difficult and the degree of greening is reduced; 2) Different parts of the slope have different soil properties, sunlight, and moisture. After a few years, the grass at the bottom of the slope will grow densely and the top of the slope will be barren because it is not easy to store water, which will affect the overall effect of slope protection; 3) For rocky edges The greening and beautifying functions are basically lost in the late stage of the slope, and the grass species basically lose their greening ability after several years of growth; 4) After the grass planting...
