The specific embodiment
Layers of material and structure among the present invention:
For the new building roof, roof greening adopts five-layer structure, i.e. waterproofing course, sluicing layer, filtration beds, plantation layer, vegetable layer.Layers of material and thickness are: waterproofing course is two-layer PVC waterproof roll, gross thickness 5mm; Layer sluices: adopt blast-furnace cinder, brickbat, broken watt, the mixture of rubble, one or more materials of broken concrete, thickness: 5-10cm; Filtration beds: adopt two-layer nonwoven, thick about 1mm; Plantation layer: adopt ground dregs (or cinder soil or both mixtures) and garbage compost, a small amount of controlled release chemical fertilizer and bacterial manure.In addition, generally also should apply some organic matters and clay to improve water retention property, thickness: the 5-15cm vegetable layer: the plantation layer according to their location weather and configuration is determined, generally based on sengreen.
The waterproof of roof greening is the key that can roof greening successful, and why two-layer PVC waterproof roll will be set, exactly in order to strengthen waterproof.Adopt heat to melt overlap joint during the construction of PVC waterproof roll, do not have the slit after the construction, this helps preventing the puncture effect (physics and root rhizosphere secreta chemical action) of root system of plant to waterproofing course, is beneficial to roof waterproof.
The layer that sluices is set on waterproofing course, except plant growing requirement draining is unobstructed, also has waterproof to need.The water pouring layer that is made of thick block materials can allow the waterproofing course upper surface reduce ponding, relatively dry after long-time rainfall.And because block materials lacks soil, root system of plant distributes seldom.This has just alleviated the destruction of root system to waterproofing materials.
The setting of filtration beds is in order to prevent that in the early stage tiny soil particle is gone out the plantation layer by rain-out in the plantation layer.After treating that vegetation is set up, filtration beds rots, and fine particle has formed certain crumb structure in the soil at this moment, is rinsed out no longer easily.
The main material of plantation layer is ground dregs, cinder soil.Ground dregs quantity is big, accounts for 30% of total building waste, and the ground dregs of a general building can satisfy this roof greening.But the ground dregs generally is the dead soil that hardens, lacks nutrition, need improve.Cinder soil quantity is bigger, also lack nutrition, and water retention property is not good.Generally need to adopt the garbage compost of 0-15% or apply durable composite fertilizer and a small amount of bacterial manure of 0.2%-1% or use the three to improve the nutrition condition of ground dregs and cinder soil simultaneously, simultaneously, often need to add the clay of 5%-20% to improve water retention property.Be to improve the content of organics of plantation layer, generally need to add the materials such as sawdust, rice husk, vinasse, crushing straw of 0-15%.
The selection of plantation layer species generally will be determined according to landscape design requirement and local climate condition, adopts plantation and sowing job practices.For reducing the drought resisting work under the regular maintenance, particularly adverse weather condition, the general sengreens of adopting more.
