Background technology
Along with the raising of living standards of the people and the enhancing of environmental consciousness, people are more and more higher to the requirement of living environment quality.Lawn planting is one of important measures of beautifying the environment, purify air, conserving water and soil.Lawn planting mainly adopts the seminal propagation method at present, though cost is low, labour's influence wasteful, that be subjected to weather is big, the maintenance management workload is big etc., and requires to have the soil of suitable grass seeds growth.
China is in the process of construction of infrastructure such as highway, railway and water conservancy, because a large amount of embankment and excavations that cuts into a mountain, form a lot of exposed slight slope and rock slopes, cause highway, railway vegetation deterioration along the line, water and soil loss, ecological disequilibrium, even cause massif to cave in and come down.Therefore need take technical measures that side slope is protected and afforested.To the effect that side slope is protected and afforested, be that side slope is carried out supporting and reinforcing on the one hand, make side slope keep stable; Be that side slope is afforested on the other hand, make its restore vegetation, ecology recovering balance, conserve water and soil.The method of at present side slope being protected and afforesting is: the thick and good side slope of soil property to soil layer, extensively adopt direct greening method, and be subjected to deficiencies such as weather effect is big, the maintenance management workload is big but mainly contain; To rock slope, its key is to provide the artificial soil that is beneficial to vegetation growth on domatic, and make this soil can be permanently affixed at rock domatic on.It is a kind of technology of rock slope being carried out ecological protection and greening of developing both at home and abroad at present that the thick-layer base material sprays bank protection.Its basic principle is that greening a base material, stabilizing agent, an agent and grass seed mix are added the water uniform mixing, then with the special-purpose ejecting machine with the mixture of uniform mixing on request thickness be ejected into domatic on.Through the maintenance management of certain hour, domatic go up will grow careless bud also progressively cover domatic, thereby reach the purpose of ecological revetment.This technology mainly contains following weak point:
(1) influences the grass seeds germinating growth.The thick-layer base material sprays the present stabilizing agent that uses of bulkhead tech and mainly contains portland cement, emulsified asphalt, synthetic resin and high molecular polymer.Wherein make base material be alkaline environment behind the silicate cement hydration, be unfavorable for growth and development of plants; To emulsified asphalt, when seed touches pitch, can hinder germination.
(2) substrate intensity is low.When stabilizing agent dosage was low, substrate intensity was low, be unfavorable for base material be fixed on rock domatic on, also be subject to rain erosion and wash away.When if stabilizing agent dosage is high, grass seeds germinates and the growth difficulty.
(3) construction costs height.Because synthetic resin and high molecular polymer price in the stabilizing agent are more expensive, make construction costs higher; Because substrate intensity is low, and particularly early strength is low, base material is difficult to fix on domatic again.Need on domatic linked network as last and fix at sprayed construction, after construction, need with coverings such as nonwoven, in case rain drop erosion with anchor pole.Thereby the work progress complexity, construction costs is raise.
The construction method of existing slope vegetation protection technology is wanted linked network before the construction as mentioned above, to cover after the construction, and the method complexity, time-consuming, the construction costs height is not easy to wide popularization and application.
