Abstract
The invention provides a stone grid type ecological slope protection method for side slope grasses of drainage ditches in a coastal reclamation area. The method particularly comprises the steps of: randomly arranging block stones with particle sizes of 5-10cm in side slope surface soil, then paving grass belts on side slope surfaces to form rectangular grids, and then fixing the grass belts on side slope soil bodies by wood nails. For one thing, the raindrop splash erosion effect of side slopes is reduced by stone block covering surfaces; and for another thing, the randomly distributed block stones form plaque-shaped hydrological paths, in combination with the blocking effect of grass belt grids, the on-site infiltration amount of the side slope runoff is increased, the runoff erosion of the side slopes is effectively reduced, due to the arrangement of the block stones embedded in the soil bodies and the grass belt grids, the integrity and structuredness of the side slopes are enhanced at the same time, and the slope protecting and stabilizing effects are achieved. The method is simple in construction, low in engineering cost, strong in adaptability, safe and reliable, and has the characteristics of ecological and scenic properties.
Description
Technical field
The invention belongs to side slope protection technical field, be specifically related to a kind of coastal district's drainage channel side slope grass stone grid-net type ecological revetment method of enclosing and cultivating.
Background technology
In recent years, hydraulic engineering construction domatic soil erosion problem in coastal Tidal Flat Reclamation district progressively causes extensive attention.Especially drainage channel side slope, because becoming in the process of land, beach is subject to seawater to ooze assorted impact, Tidal Flat Reclamation district salt accumulation in soil process is prior to soil-forming process, soil is mainly high sodium salt silt, resistance to corrosion is poor, add that this district's rainfall is plentiful, raceway groove slope soil erosion is serious, cause side slope unstable, being easy to bring out the domatic soil body slides or caves in, and up to the present, side slope protection technology for coastal Tidal Flat Reclamation district soil property is very limited, substantially in zero treatment state, so the safeguard procedures that propose suitable coastal beach drainage channel side slope surface erosion control in the urgent need to, in coastal beach area, there is important applied value and wide popularizing application prospect.
Summary of the invention
The object of the invention is to: poor for coastal Tidal Flat Reclamation district side slope soil resistance to corrosion, erosion damage is serious, the phenomenons such as soil erosion outstanding problem, suitable coastal beach area is proposed for the safeguard procedures of drainage channel side slope surface erosion control, to improve the stability of side slope and structural, for solving coastal Tidal Flat Reclamation district Problems of Slope Stability, provide strong help.
Technical scheme provided by the invention is: the present invention refers to the stone that random arrangement particle diameter is 5～10cm in side slope soil top layer, make stone be embedded in the soil body, insert depth is about 1/2 of stone particle diameter, stone coverage rate is controlled at 30%～60% of the side slope gross area, the artificial patch shape soil-rock mixture structure that constructs on side slope soil top layer like this, in domatic formation patch shape hydrology path, with this, increase footpath flow path, subdue runoff and wash away kinetic energy, strengthen the infiltration capacity on the spot of side slope runoff, can also utilize the coverage rate of stone effectively to reduce the suffered raindrop sputter destruction of side slope.In addition, with width, be 8cm, thickness is that the straw cord of 2cm is layered on side slope surface, the rectangle grid that the formation length of side is 60cm, and four jiaos of grids, straw cord is fixed on to slope soil with wooden peg, graticule mesh on the one hand has in domatic formation the cell of retaining runoff function, with the stone structure that is embedded in the soil body, slope soil is played to the effect that reinforcement adds bone simultaneously, can improve the globality of the domatic soil body and structural.30%～60% stone area control can guarantee the ecological property of this method, also possesses certain view simultaneously.
Beneficial effect of the present invention is:
1, the present invention is embedded in the domatic soil body by stone, utilizes the hard speciality of stone effectively to reduce the sputter destruction of raindrop to side slope, can also increase the structural of domatic topsoil.
2, the present invention, by stone random arrangement at slope soil, in the domatic patch shape hydrology path of constructing, had both increased footpath flow path, had played again the effect of subduing runoff scouring capability.
3, the present invention utilizes straw cord in the domatic continuity graticule mesh of setting up into, can either play and retain runoff, increases the effect of infiltrating on the spot of runoff, has strengthened again the globality of the domatic soil body and structural.
4, the present invention is controlled in 30%～60% scope of side slope area stone coverage rate, has guaranteed the ecological functions of edge slope structure.
5, the present invention draw materials convenience, reasonable in design, construction is simple, cost is low, also possesses ecological property and view simultaneously, in coastal beach area, even in other regional side slope protection field, there are promotion and application widely and be worth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is section of structure of the present invention
In figure, 1-straw cord, 2-side slope soil, 3-stone, 4-wooden peg.
The specific embodiment
Below in conjunction with accompanying drawing, the mode by embodiment, is elaborated to technical solution of the present invention, but protection scope of the present invention is not limited to described embodiment.
As shown in Figure 1, the stone 3 that random laying particle diameter is 5～10cm in side slope soil 2 top layers, make stone 3 embed side slope soil 2, insert depth is about 1/2 of stone particle diameter, stone 3 coverage rates are controlled at 30%～60% of the side slope gross area, the artificial patch shape soil stone combination construction that constructs on side slope soil 2 surfaces like this, on side slope soil 2, form patch shape hydrology path, the infiltration capacity on the spot that strengthens side slope runoff with this, can also utilize the coverage rate of stone 3 effectively to reduce the destruction of the suffered raindrop sputter of side slope.In addition, with width, be 8cm, thickness is that the straw cord 1 of 2cm is layered on side slope soil 2 surfaces, the rectangle grid that the formation length of side is 60cm, and four jiaos of grids, straw cord is fixed on to the soil body with wooden peg, graticule mesh forms and has the cell of retaining runoff function on the one hand on side slope soil 2, plays the function of strengthening side slope soil 2 overall structures simultaneously.30%～60% stone 3 area controls can guarantee the ecological property of the inventive method, have played bank protection Gu Po effect, have also possessed certain view simultaneously.
