Description
Technical field
The invention belongs to geotechnical engineering side slope protection field, particularly relate to a kind of ecological bank protecting method of shallow-layer slide slope disease punishment.
Background technology
Side slope is a kind of common surface configuration.Stable side slope will be brought benefit to the mankind, and bring safe environment to the production of people, life; But side slope is once unstability, its disaster will be very serious.At present, the attention that large-scale slope instability causes everybody enough, but a lot of people have ignored the impact of the small-sized slope instability of shallow-layer.The small-sized side slope of shallow-layer, except having the characteristics such as sudden, speed is fast, quantity is many, is brought outside danger to the life of the people, property, trip facility, ripely talks about " causeway is burst in ant cave ", and the small-sized landslide of shallow-layer causes the main source of the unstability of large-scale side slope especially.Overwhelming majority large-sized artificial side slope (embankment and execavated rockmass) all designs according to safety standard in the design, but but often still slump unstability occurs, and major part of tracing it to its cause eventually all from outward appearance to inner essence develops.Analyze its reason, be mainly divided into three aspects, one, shallow-layer slope, side slope middle and lower part body produces shallow-layer slump by external factors such as rainwater, and upper slope loses and supports and produce whole slide formation Large Deep landslide; It two is domaticly subject to rainwater erosion, serious to the infiltration of slope body inside, causes slope soil or weak structural face shear strength to reduce, and produces Large Deep landslide; Its three, the special soil body, due to the strong variations of weather, from outward appearance to inner essence produces drying shrinkage or expansion, causes major landslip.Therefore in design side slope, must the strict improvement considering shallow-layer face.By administering shallow-layer face, and eradicate may shallow-layer weak spot from outward appearance to inner essence; By administering shallow-layer face, and reach improvement water infiltrating to slope, deep body; By administering shallow-layer face, and slowing down slope body internal steam strong variations, slowing down the deformation of special soils, ensureing the stable of slope soil.
Existing side slope surface administering method, of a great variety, as direct turfing, grass seeds of sowing grass seeds by duster, hang Three-Dimensional Network Seeding, thick photoresist grass planting, plant biological bag etc.Be that method all has some shortcomings: as direct turfing intricate operation, the time is long, and it is large to transplant turf transport amount, after transplanting, scour resistance is weak, fails to slow down rain infiltration and erosion slope body within a very long time; Sow grass seeds by duster grass seeds, directly grass seeds is sowed grass seeds by duster in side slope, low price, easy construction, but side slope surface does not possess erosion resistibility, and grass seeds affects by rainwater wind, survival rate is not high, DeGrain; Thick photoresist grass planting, extension Three-Dimensional Network Seeding, plant biological bag are all utilize carrier to be afforested in side slope by grass seeds etc., play good firm domatic effect, but thick photoresist is higher with extension three dimensional network cost, and the plastic products materials such as three dimensional network have certain destruction to ecological environment, plant biological bag bank protection rainwater is domatic from the gap seepage scour between plant biological bag, domatic antiscour DeGrain.In a word, current slope protection greening method is various, respectively has pluses and minuses, has utilization to side slope protection, and achieves good effect.But not yet have at present a kind of possess cheap, erosion resistibility strong, construction simple, impermeability is strong, method to multiple advantages such as zero environmental.
Summary of the invention
