Along with the raising of people's living standard, also more and more higher to the harmonious requirement of road slope ecological environment, the guard technology of different kinds of roads side slope continues to bring out.In the tractor-ploughing road construction of mountain area,, often take the safeguard procedures based on engineering properties such as the greening of sash soil moved in to improve the original, mortar flag stone, spraying and seeding afforesting in the engineering reality for rock side slope.These bank protection measures, or with high costs, or on anti-mask, form on the spot environment of hard that plant is difficult to survive, afforestation vegetation is difficult to recover, and has both influenced the beautification of landscape of road slope, is difficult to the protection effect that reaches permanent, firm again.And for the soil is porous area, traditional side slope protection method is the grass planting bank protection, plant give birth to band, grass is irritated protection forms such as combination.These are based on the protection form of ecological vegetation bank protection, though reached the effect of greening side slope, this class measure can only be satisfied with shallow-layer Gu Po.The soil is porous the area, as purple soil hills area in the river, the decomposed granite hills area, because these traditional bank protection forms can't effectively be controlled and guide slope runoff, under the heavy rain condition, deep layer slope body is infiltrated in rainfall, increase sloping body deadweight, reduce the soil cohesion, geological disasters such as easy as rolling off a log generation landslide, avalanche, serious threat road traffic safety.

Though it is extensive gradually that new technologies such as present flexible bank protection, eco-concrete are used, its high cost has restricted its popularization in vast rural area.Especially for rural area tractor-ploughing road slope, at village level often government or the spontaneous build of peasant, appropriation budget is limited, construction technology strength weakness, the higher height cost bank protection mode of many scientific and technological contents is difficult to carry out.

Therefore, at the hills area that the soil is porous, rural area tractor-ploughing pavement of road is narrower, cut slope is not high, constructor's technical level features of limited, develop a kind of easy safeguard structure, can prevent loose soil body damage tractor-ploughing road, can have bigger realistic meaning with the green gallery that comparatively economic mode is constructed between the farmland again.

Summary of the invention

The purpose of this utility model provides the loose simple and easy ecological slope protection structure of soil-slope of a kind of road, by changing domatic, control rationally and guiding slope flow path, and carry out ecological vegetation in conjunction with the greening side slope theory and protect, it is as a whole to make that each several part organically combines into, thereby reaches the purpose of slope stabilization, roadside greening, smooth traffic.

The technical solution of the utility model is: the road simple and easy ecological slope protection structure of soil-slope that loosens, comprise retaining wall 1 and support column 4, it is characterized in that: also comprise water proof substrate 2 and waterwall 3, have drain hole 8 on the retaining wall 1, waterwall is higher than drain hole, and 3 of upper strata water proof substrate 2 and lower floor's waterwalls have penetrating interval 9.

The aforesaid road simple and easy ecological slope protection structure of soil-slope that loosens is characterized in that: support column 4 or water proof substrate or shelves waterwall below have feet 5, feet 5 to be positioned at a below with layer water proof substrate 2 planes.

The utility model is on the basis of traditional retaining wall and ecological revetment, build form by changing original retaining wall, build one deck water proof substrate and waterwall in bank face bottom, the upper and lower surface retaining wall is coupled together, prevent that slope runoff is to deep percolation, because waterwall will be higher than drain hole, the domatic rainfall in upper strata by drain hole to the descending transmission, transmit layer by layer by this, most of slope flow imports road ditch along structure, greatly reduce the infiltration capacity of domatic rainfall, thereby reduced landslide, the avalanche of the soil body.

Between retaining wall and waterwall, build the concrete support column at a certain distance, support the top retaining wall on the one hand, on the other hand, up and down between the water proof substrate reserved part original soil slope be beneficial to root system of plant and stretch, so both solve the stable problem of structure, and can not hinder the normal growth of dark root greening shrub kind again.Form feet in the concreting stake of waterwall bottom and penetrate sloping body, fixedly whole member prevents that member is subjected to displacement and is located.

Whole member is built by laying from bottom to top step by step, forms stepped.Earthing is filled cultivation matrix in terrace structure, fills and leads up compacting, serves as the main greening vegetation that carries out in the mode of draft and shrub combination.This ecological side slope protection measure, the area that is particularly useful for that the soil is porous is as purple soil hills area in the river, decomposed granite hills area etc.This technology reduces sloping body moisture and infiltrates the unsettled dominant factor of this sloping body in the vegetative protection of top layer, thereby has reached the requirement of " practical, economic, attractive in appearance ".
