Description

The method that grass-leaved sweetflag is planted in side slope

Technical field

The present invention relates to ecological protection technology field, it is more particularly related to which one kind plants stone Chang in side slope The method of Pu.

Background technology

During highway construction, municipal works or gardens project construction, because engineering soil stone fills out digging etc., a large amount of soil are formed Stone bare side sloping, exposed side slope not only influences landscape harmonious, and side slope is under rainwash, easily causes side slope rock matter or soil Mass flow is lost, or even occurs cave-in accident.Simple engineering protection is generally used in the past, such as starches (dry) block slabstone and spray anchor protection Deng these engineering measures result in a series of ecological environments such as original vegetation deterioration, soil erosion, landslide, slope instability and work Cheng Wenti.Therefore, need rationally to utilize resource in engineering construction.

Traditional side slope restorative procedure is mainly repaired from side slope on plant or engineering structure, is planted in side slope Plant can recover side slope vegetation landscape to a certain extent, but can not form firm edge slope structure, and side slope soil is easily by rain Water washes away loss；Engineering structure processing mainly takes slurry is (dry) to build the method such as slabstone and spray anchor protection, though these processing methods Firm edge slope structure can be formed, but original vegetation can be destroyed, it is impossible to forms vegetation landscape, recover the side slope vegetation ecosystem.

Eco-concrete protecting slope ecology is the mode being combined with plant living or plant and non-living material, instead of Pure engineering protection, by the mutual winding between the adhesive force and root system between root system of plant and soil come soil and slope protection, raising side The erosion resistibility on slope, plays a part of stable side slope and prevents from corroding.The eco-concrete of high intensity can side slope progress Protection, also alleviates and sows plant in side slope and the problem of plant growth is unable to antiscour initial stage, simultaneously for side slope significantly The ecological balance and greening have great importance.

The content of the invention

It is an object of the invention to provide a kind of method that grass-leaved sweetflag is planted in side slope, the present invention can form stable side slope Safeguard structure, can protect side slope soil not by rain drop erosion, protect side slope soil not weather, with the function that conserves water and soil；Together When can form complete vegetation landscape, improve the ecological environment.
