Problems solved by technology

[0006] And vegetation concrete is a kind of can adapt to plant growth, has positive effect to adjusting ecological balance, beautifying the environment, realizing the coordination between human and nature, but the vegetation concrete of prior art all adopts gravel or sandstone as aggregate, so on the one hand While improving the ecological environment, on the other hand, quarrying and sand mining have destroyed the ecological environment

preparation example Construction

[0032] The preparation method of described soil conditioner is specifically:

[0033] The first step is organic modification of attapulgite, take 400g of attapulgite and suspend in 4L with a concentration of 0.01g / ml -1 In the dehydrated ethanol solution of cetyltrimethylammonium bromide, stir at a constant temperature of 70°C for 8h and then filter with suction, then wash the free quaternary ammonium salt with a large amount of ethanol, and the solid isolate is vacuumed at 40°C drying and grinding to obtain organic attapulgite;

[0034] In the second step, add 700g of acrylamide to the reaction container, add 2L of water to dissolve, add 70g of the organic attapulgite prepared in the first step and 25g of N,N'-methylenebisacrylamide after the dissolution is complete, Raise the temperature to 40°C and add 30g of ammonium persulfate to react for 3h, then add 2L of NaOH solution with a molar concentration of 1mol / L, raise the temperature to 95°C and react for 1h, after the reac...

[0068] The preparation of embodiment 1 organic compost

[0069] Fully mix 60kg of urban domestic sludge, 40g of waste plants and 50g of livestock and poultry manure, adjust the water content of the mixture to 45% to 50%, control the C / N ratio at 20:1 to 30:1, and put the mixture into a closed space The first fermentation is carried out in the room, the fermentation time is 14h~20h, and then the ventilation is started in stages, the ventilation time is 15min~20min per hour, and the air flow rate is 0.1m 3 / min·m 3 , lasted for 10d-15d, then placed the obtained product outdoors, turned the pile once a day, and piled it for 18d-20d to obtain organic compost.

Embodiment 2

[0070] The preparation of embodiment 2 Chinese herbal medicine nutrient

[0071] 55g of Astragalus, 40g of Atractylodes macrocephala, 25g of Caulis Spatholobus, 30g of Dendrobium, 40g of Fructus Cnidii, 30g of Acanthopanax, 20g of saponins, 20g of tangerine peel, 25g of honeysuckle, 35g of Coptis chinensis, 15g of Baibu, 20g of Baijiucao, 15g of mulberry parasites, Mix 25g of turmeric and 15g of Herba sativa, add 1.3kg of ethanol with an alcohol concentration of 95%, heat and reflux for extraction for 3 hours, filter, add 3 times the mass of ethanol with an alcohol concentration of 95% to the filter residue, and heat and reflux for extraction After 3 hours, filter, combine the filtrates, concentrate to remove ethanol, and dry to obtain Chinese herbal medicine nutrient.

Abstract

The invention provides special vegetation concrete for slope protection and greening. The special vegetation concrete comprises the following raw materials: cement, soil, plant fiber, a polyacrylamide soil improver, thin steel bars, an organic compost, plant seeds, a Chinese herbal medicine nutritional agent, an alkaline neutralizing agent and water. The thin steel bars are added in the vegetation concrete provided by the invention, so that the strength after setting is increased; furthermore, the using amount of the cement is reduced, the alkalinity of the concrete is reduced, and the vegetation concrete is more suitable for the growth of plants; by adding the polyacrylamide soil improver, the germination and emergence rate of crops can be improved, the growth and the development of the crops are promoted, and water-retaining and fertilizer-saving performances are simultaneously and obviously improved; and by adding the Chinese herbal medicine nutritional agent for providing nutritional ingredients for the growth of the seeds, the growth is promoted, pores of the concrete are increased, the alkalinity is reduced, and the final survival rate of the plants can achieve above 95%.

Description

technical field [0001] The invention relates to the technical field of ecological restoration engineering, in particular to a novel vegetation concrete. Background technique [0002] The research on vegetation concrete originated in the early 1990s. Japan first began to study greening concrete, won a patent, and established a greening design research committee on concrete structures. The United States and European developed countries have also carried out research and development of vegetation concrete since the end of the 20th century. [0003] The development and application of vegetation concrete in our country is getting more and more attention. The slope protection vegetation concrete developed by Beijing Urban Construction Engineering Research Institute is composed of cement, gravel, sand, ceramsite and water. Jilin Provincial Water Conservancy Company used construction waste bricks and stones as aggregates to develop an environmentally friendly stick-on-stick protect...
