Detailed description of the invention
Referring to figs. 1 through Fig. 6 over the ground storehouse top board drainage system be described further.
Referring to figs. 1 to Fig. 2, storehouse, a kind of ground top board drainage system, comprise set gradually green vegetation layer 1, plantation soil layer 2, filtration beds 3, water-storage-drainage layer 4, stopping area 5, top board basic unit 6, being provided with a sloping layer 7 and a leveling layer 8, leveling layer 8 between stopping area 5 and top board basic unit 6 around sloping layer 7 outer ring is in the edge of top board basic unit 6, the surface of top board basic unit 6 is provided with some collecting gutters 11, the side of top board basic unit 6 is provided with the outer discharge mouth of a river 10 be communicated with leveling layer 8, and the outer discharge mouth of a river 10 is communicated with collecting gutter 11.
In this programme, with reference to Fig. 3, water-storage-drainage layer 4 is provided with drainage plate 5, drainage plate 5 comprise base plate 12 and circular cone convex 13, circular cone convex 13 is arranged with Y-direction linear array in X direction along base plate 12 surface, circular cone convex 13 inside is provided with hollow storage chamber 14, and the position of base plate 12 between adjacent four circular cone convexes 13 is provided with drain hole 15.The arranging of circular cone convex 13 is formed on the one hand can the cavity of retaining, stores the water yield form isolating frame dead level on the other hand, good heat insulating function to vegetation.The shortcoming that after the arranging of drain hole 15 effectively prevents earthing, geotextiles is sunk, keeps the drainage space that bottom is unobstructed.
Further setting: adjacent four circular cone convexes 13 are formed square, are provided with the reinforcing rib 16 connecting circular cone convex 13 between two along this square diagonal.Reinforcing rib 16 greatly strengthens the support degree between circular cone convex 13, is convenient to curling on the one hand; On the other hand, the weakness of coiled material intensity not as sheet material is overcome.
In this programme, drainage plate 5 adopts high-density polyethylene material to make.Compressive strength is high, and good permeability, water guide effect are better, effectively can derive rainwater fast, greatly reduce the hydrostatic pressing even eliminating waterproofing course, can effectively can reduce indoor 14 decibels by polyethylene drainage plate by this active water guide principle, the noise of 500HZ, has obvious noise abatement sound insulation function.
In this programme, stopping area 5 is density polyethylene film with high.Have every the anti-puncture function of root with to building waterproof layer available protecting.
In this programme, the surface of sloping layer 7 is inclined to set, and gradient is 0.5%.The slope of sloping layer 7 makes to dredge the outer discharge mouth of a river 10 place by organized for rainwater, finally passes in the storm-water system in city and goes.
In this programme, filtration beds 3 adopts polyester non-woven fabric, and stopping area 5 adopts polymer modified bituminous waterproof sheet material, and sloping layer 7 adopts light ceramsite concrete.Light ceramic as a kind of light aggregate, have that density is little, intensity is high, water absorption rate is large, insulation, the feature such as heat insulation, fire-resistant, antidetonation, be a kind of well porous pavement material.
Discharge the position at the mouth of a river 10 outside, be located at the structure by rainwater-collecting or discharge, this structure has multiple, enumerates three kinds of better embodiment in this programme.
Embodiment one, with reference to figure 4, the outer discharge mouth of a river 10 place establishes gutter 9, and gutter 9 is communicated with collecting gutter 11.
Embodiment two, with reference to figure 5, the outer discharge mouth of a river 10 place is provided with gutter 17, and gutter 17 one end is communicated with the outer discharge mouth of a river 10, and the other end is connected to bottom of the reservior portion, ground, and is provided with plash 18 in bottom of the reservior, ground portion.
Embodiment one, with reference to figure 6, the outer discharge mouth of a river 10 place is provided with rubble and french drain 19, is connected with flexible porous tube 20 in french drain 19.
In above-mentioned three kinds of embodiments, by being provided with some collecting gutters 11 on the surface of top board basic unit 6, rain penetration trickling is to catchmenting in ditch, the outer discharge mouth of a river 10 is guided to through collecting gutter 11, rainwater is circulated in gutter 9 or plash 18 or french drain 19 through the outer discharge mouth of a river 10, the effect of gutter 9 or plash 18 or french drain 19 is all the position of temporarily collecting rainwater as, by the edge of rainwater-collecting in top board basic unit 6, do not affect vegetation in top board basic unit 6, vegetation is not soaked by ponding, motility rate of withdrawing deposit.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
