The plant growing matrix prepared by the construction wastes has the benefits as follows: a new way for disposing the construction wastes is provided; the land consumption and waste cleaning and transporting fees for disposing the construction wastes by the conventional method are greatly saved; blockage to a soil biological chain by landfill is avoided; the secondary pollution caused by the construction wastes to the environment is greatly reduced; and the nutrient soil has a good effect of preserving moisture and fertility and can be applied to roof greening, slope greening and other engineering.
Description
Technical field
The present invention relates to a kind of plant growth medium, especially a kind of plant growth medium with the building waste preparation.Can be applicable to roof greening, greening side slope and other afforestation projects.
Background technology
In new town like a raging fire is built, reconstruction of village-in-city, tear open face demolish squatter buildings, the engineering construction paces such as reconstruction of the old city town constantly accelerate, when the city became more and more U.S., the building waste generation was but growing with each passing day.Building waste can be divided into the five large class rubbish such as soil excavation, road excavation, old building dismounting, building operation and production of construction materials according to the source, mainly be formed by dregs, crushed stone, waste mortar, brick and tile fragment, concrete blocks, asphalt blocks, plastic waste, scrap metal material, useless bamboo wood etc.
At present, in the developed country such as American-European-Japanese, most building waste can be carried out recycling, make some building materials etc.And the treatment process of China's urban architecture rubbish rests on two types substantially, the one, carry out direct landfill without the building waste of any processing, and account for 98%; The 2nd, slightly sort out scrap metal, waste concrete, only account for about 2%.According to international method of determining and calculating, per ten thousand tons of building wastes take 1 mu in the soil of landfill yard, and the annual building waste landfill floor space that produces in China city will go up 100,000 mu.The stock building rubbish of processing over 20 years needs 240,000 mu of land occupations, not only consumes a large amount of soils and refuse collection expense, and garbage loading embeading can block the soil organisms chain, causes serious environmental pollution, forms permanent harm.
Aspect the building waste improvement and recycling of China, all be for the making building material basically, its starting material as Nutrition Soil are not used, for example following patent:
