The utility model content
To the problems referred to above, the utility model discloses the planting technique slight slope structure of low, the easy to operate attenuating floor load of a kind of cost.
The technical scheme of the utility model is such: a kind of planting technique slight slope structure that lowers the floor load; Each layer is from top to bottom: outer topsoil, coating geotechnique layer of cloth, foam sheetpile, bottom geotechnique layer of cloth, hydrophobic layer and watertight composition, close proximity between each layer.
In above-mentioned a kind of planting technique slight slope structure that lowers the floor load, described outer topsoil is sloping shape.
Above-mentioned a kind of planting technique slight slope structure that lowers the floor load, described coating geotechnique layer of cloth edge should go out 30～100cm than foam sheetpile layer edge is wide.
The used cystosepiment of present technique is expandable polystyrene plate (EPS), and its correlated performance is following:
A. owing to 95% be air in its volume, unit weight is extremely light, density 20～60kg/m
3
B. compressive strength 80～300kPa, earthing height theoretical maximum reaches more than 10 meters on it.Select the proper compression strength specification for use in response to cost control and actual requirement in the practical operation of gardens.
C. warm tolerance is general, when temperature is higher than 70 ℃, foams along with the increase of the blowing agent that discharges; 220 ℃ (approximately) begins to decompose, and uses and should note avoiding when depositing.
D. nontoxic, waterproof, corrosion-resistant, insulation, water insoluble, but be dissolved in organic solvent, should avoid contact.
E. physical and chemical performance is stable under the normal temperature normality, and the years up to a hundred are wanted in degraded under the nature.
F. easy compressive deformation, under the power effect that reaches its compressive strength, volume compression is out of shape about 10%.In addition, in long-term use, the dynamic load of top earthing can make it produce fatigue strength, thereby the bearing capacity of plate is descended, and distortion further strengthens, and generally needs the time more than 50 years and this situation occurs.So the height suggestion of using present technique backfill foam sheetpile is in 3 meters.
Compared with prior art, the utlity model has following beneficial effect:
1. at the bottom of the cost, the duration is short, and comprehensive unit price is about 180～200 yuan/cubic metre, is 1/2 of light soil backfill, 1/3 of pure haydite backfill; It is backfill that cystosepiment is promptly piled, and need not any building by laying bricks or stones and surrounds;
2. constructing operation is convenient, only need simply pile up and fix simple operation;
3. backfill is highly big, satisfies the greening landform fully and piles sloping requirement;
4. the draining hydrophobic performance is good, and foam belongs to hydrophobic material, and the following infiltration of soil can flow to the bottom hydrophobic layer fast on the foam pile surface, does not produce ponding;
5. top board structure there is not influence; The foam moisture content is extremely low, and the back foam pile of raining can not absorb water and increase unit weight, and haydite and light soil moisture content behind rain is high; Particularly can increase by 2～3 times, moment live load that can be very big under the situation that water fails in time to drain to the top board increase at unit weight when raining heavyly;
6. plant and plant superincumbent shrub wind resistance and not influence of steadiness.
