In this planted roof system, waterproofing course is disposed with from the bottom to top below plantation module layer, water draining and accumulating plate, geotechnique's filter cloth, waterproofing course adopts one deck waterproofing materials, such as complex copper tire base SBS modified asphalt waterproof coiled material, Copper Foil tire SBS modified asphalt waterproof coiled material, SBS modified bitumen root resistant waterproof roll etc., for preventing rainwater infiltration, also can avoid being pierced through by plant roots simultaneously, protection roof panels, water draining and accumulating plate is for discharging percolating water and saving partial penetration water, to ensure the retaining moisturizing effect of planted roof system, geotechnique's filter cloth is every soil not water proof, be convenient to percolating water and infiltrate through water draining and accumulating plate for isolation implant soil, block waterwall outer being arranged with of plantation module layer, this blocks waterwall and can prevent rainwater from entering in water draining and accumulating plate just directly excessive without permeation filtration, ensures the retaining moisturizing effect of planted roof system, the descending of roof panels is provided with and is positioned at this and blocks rain drainage system outside waterwall, can make to overflow the unnecessary rainwater blocking waterwall and be drained by rain drainage system, plantation module layer comprises a plurality of plantation module be arranged side by side, and modularization is arranged so that construction becomes simple, reduces construction reformation difficulty and shortens the engineering time, plantation module comprises planting bag, planting soil and vegetable layer, during rainfall, due to the interception function of vegetable layer and planting soil, rainwater fashionable colors is extended, a large amount of rainwater permeates lentamente to be accumulated in each layer medium (geotechnological filter cloth, water draining and accumulating plate), unnecessary rainwater is then by entering city planting ductwork after rain drainage systematic collection, and retaining moisturizing is effective, can effectively reduce Rainfall runoff and runoff pollution.
This planting soil is provided with shredded coconut meat bed course.The filamentary fibers that shredded coconut meat bed course is processed into by coconut husk is made, and the setting of shredded coconut meat bed course can prevent the planting soil caused because of rain drop erosion to run off effectively, and shredded coconut meat bed course also can be vegetable layer simultaneously provides nutrition, meets the nutritional need of plant.
Flexible cover sheet is provided with between waterproofing course and water draining and accumulating plate.Flexible cover sheet is arranged between waterproofing course and water draining and accumulating plate and plays cushioning effect, prevents waterproofing course to be damaged, and improves the application life of waterproofing course.
This rain drainage system comprises gutter, the gutter of the discharge opening be opened on gutter, connection discharge opening and municipal drainage pipe network.Structure is simple, unnecessary Water in Rainwater Drainage can be entered in municipal drainage pipeline networks.
The drainage grade of this roof panels adopts 1-2%.This drainage grade arranges the retaining moisturizing effect that can ensure planted roof system further, and effectively reduces Rainfall runoff.
The beneficial effect that the utility model brings is:
1, rainwater fashionable colors is extended, a large amount of rainwater permeates lentamente to be accumulated in each layer medium (geotechnological filter cloth, flexible cover sheet, water draining and accumulating plate), unnecessary rainwater is then by entering city planting ductwork after rain drainage systematic collection, retaining moisturizing is effective, can effectively reduce Rainfall runoff and runoff pollution;
2, modularization is arranged so that construction becomes simple, reduces construction reformation difficulty and shortens the engineering time.

Detailed description of the invention
As Figure 1-4, a kind of planted roof system, be arranged in the roof panels 1 of inclination, comprise the waterproofing course 2 be laid in this roof panels 1, be laid on the water draining and accumulating plate 4 on waterproofing course 2, be laid on the geotechnological filter cloth 5 on water draining and accumulating plate 4, be laid on the plantation module layer on geotechnological filter cloth 5, the descending of this roof panels 1 is provided with rain drainage system, and be provided with between plantation module layer and rain drainage system vertically arrange block waterwall 10, wherein, plantation module layer comprises a plurality of plantation module be arranged side by side, each plantation module comprises planting bag 6, be arranged on the planting soil 7 in planting bag 6, and the vegetable layer 9 be arranged on planting soil 7.
In this planted roof system, waterproofing course 2 is disposed with from the bottom to top below plantation module layer, water draining and accumulating plate 4, geotechnique's filter cloth 5, waterproofing course 2 adopts one deck waterproofing materials, such as complex copper tire base SBS modified asphalt waterproof coiled material, Copper Foil tire SBS modified asphalt waterproof coiled material, SBS modified bitumen root resistant waterproof roll etc., for preventing rainwater infiltration, also can avoid being pierced through by plant roots simultaneously, protection roof panels 1, water draining and accumulating plate 4 is for discharging percolating water and saving partial penetration water, to ensure the retaining moisturizing effect of planted roof system, geotechnique's filter cloth 5 is every soil not water proof, be convenient to percolating water and infiltrate through water draining and accumulating plate 4 for isolation implant soil 7, to be provided with near the side of roof panels 1 descending at plantation module layer and to block waterwall 10, this blocks waterwall 10 and can prevent rainwater from entering in water draining and accumulating plate 4 just directly excessive without permeation filtration, ensures the retaining moisturizing effect of planted roof system, block waterwall 10 away from plantation module layer side be provided with rain drainage system, can make to overflow the unnecessary rainwater blocking waterwall 10 and be drained by rain drainage system, plantation module layer comprises a plurality of plantation module be arranged side by side, plantation module is prefabricated in advance, when constructing, the plantation module that each is prefabricated is placed on geotechnological filter cloth 5, fix with pin between plantation module, the place loosened is inserted planting soil again and is fiddled with closely, modularization is arranged so that construction becomes simple, reduces construction reformation difficulty and shortens the engineering time, plantation module comprises planting bag 6, planting soil 7 and vegetable layer 9, during rainfall, due to the interception function of vegetable layer 9 and planting soil 7, rainwater fashionable colors is extended, a large amount of rainwater permeates lentamente to be accumulated in each layer medium (geotechnological filter cloth 5, water draining and accumulating plate 4), unnecessary rainwater is then by entering city planting ductwork after rain drainage systematic collection, and retaining moisturizing is effective, can effectively reduce Rainfall runoff and runoff pollution.Meanwhile, planting die blocking arranges different plant variety of can arranging in pairs or groups when constructing, and can build the multiple moulding such as checkerboard type and quincuncial pile formula, various kind and changeable moulding can build the colourful planted roof of view.
