In embodiment, the height of filtration beds 5 is lower than 5 centimetres of the height of hypothallus 1.
The utility model has adopted a kind of draining aquifer 4 that simultaneously possesses drain hole 41 and catch basin 42, and at ordinary times, the water in hypothallus 1 mostly sees through filtration beds 5 and enters in catch basin 42, and the water in catch basin 42 returns to hypothallus 1 by evaporation, for plant.On the top of catch basin 42, be provided with a platform, have drain hole 41 on platform, if run into the situation such as rain heavily, catch basin 42 can storage full waters, and then unnecessary water diffuses out catch basin 42, by drain hole 41, discharges.By draining aquifer 4, can effectively preserve moisture, can also discharge unnecessary water, kill two birds with one stone simultaneously.
Concrete laying step of the present utility model is: cleaning roof surface, roof is carried out to retaining test and the examination of water-proof leveling layer, defective if retaining test and water-proof leveling layer are checked and accepted, prove that there is drainage on roof, carry out waterproofing work, until roof no longer leaks.Then at roof preposition, lay waterproof layer 2, on waterproof layer 2, lay every root layer 3, draining aquifer 4, filtration beds 5, then the barricade 6 of greenery patches planting bed is constructed, road between adjacent roof greening piece is constructed, on filtration beds 5, lay again hypothallus 1, planting plants on hypothallus 1, covering surfaces covering layer on exposed hypothallus 1, such as lawn etc.
Roof greening is secondary buildings waterproof; for guaranteeing the safety of roof structure, before roof greening, on basis, former roof, should carry out secondary waterproofing work; within making the protection of original building waterproofing course surface in roof greening planting matrix and layer of plants, thus the application life of prolongation waterproofing course.
Roof greening will be considered the thrust of planting soil frost heave to building abutment wall.In order to meet, building wall is kept a public place clean and the needs of facade waterproof, and growing surface should not be directly adjacent to building abutment wall, should, according to different designing requirements, reserve the interval of proper width.
Greening construction should, strictly by operational procedure construction, be noted protection waterproofing course.The garden engineering facilities such as pond, should adopt independent waterproofing system.
Should make regular check on roof afforestation structure equipment (delivery port and inspection shaft), clear up in time dry branches and fallen leaves, prevent that outfall is blocked, cause and choke water refluence, jeopardize plant growth and waterproof safety.
The root system of some plants has very strong puncture ability, can threaten to architectural waterproof material structure.Every root layer 3, can prevent that root system of plant from penetrating waterproof layer 2, especially the plant of well developed root system more will be considered to add every root to process.
Material category is selected aluminium alloys (PSS) composite thermoplastic coiled material, high density high tenacity polyethylene (HDPE), low density polyethylene (LDPE) geomembrane (LDPE), polyvinyl chloride (PVC) coiled material etc.
In addition, on market, some waterproofing materials is metal material or contains metal material, all has every root effect, can select as required application.
Draining aquifer 4 can improve the aeration status of matrix, absorbs the excessive moisture that plantation layer oozes out, and provides plant required moisture during soil lack of water; Rainwater can be discharged rapidly, effectively alleviate the instantaneous concentrated rainfall pressure that load-bearing causes to roof.
Draining aquifer 4 materials should possess the feature of ventilation, draining, water storage and light weight.Main material type comprises: row's (holding) water plate with draining, two functions of retaining; The band drain that only has drain function; Pottery gravel draining (using when loading allows); Gutter draining (using when the roof drainage gradient is larger).
Filtration beds 5 can prevent that planting matrix from being brought into drainage blanket by water, causes the obstruction of soil erosion and building roof drainage system.Material is selected can permeable filtrable nonwoven or glass fiber material again.The weblike material preferably being formed by double layer material.Upper strata is the retaining cotton that has Water storage concurrently, 200～300g/m
2; Lower floor is nonwoven cloth material (polypropylene or polyester material, the 100～150g/m that has filtration
2).Laying method: filtration beds 5 is laid on below hypothallus 1.The effective width of overlapping the slot must reach 10～20cm.And extend to building side wall, should be lower than planting matrix layer height 5cm.
Matrix is the important component part of plantation layer, is generally light weight matrix, can alleviate the burden of roof load.
The kind of matrix mainly comprises conditioned soil and two types of artificial light weight matrix.
Conditioned soil is in natural soils, to add improvement material, alleviates loading, improves water retention and the aeration of matrix.Its preparation is mainly by draining material (cinder, sandy soil, vermiculite etc.), and aglite (fermentation wood chip, chopping weeds, leaf chaff, perlite etc.) and fertilizer (humus soil, peat, plant ash etc.) mix.
The configuration proportion of conditioned soil can be determined according to the situation of various places current material, can also be according to the preparation that needs of all kinds of plant growths.General dry density is at 550～900 kg/m
3between, if matrix fully absorbs after moisture, its wet density can increase 20～50%, therefore, in process for preparation, should consider according to wet density, reduces as far as possible unit weight, and suitably adds and supplement fertilizer, its ratio can need determine according to growing of different plants.
Artificial light weight matrix is comprised of surface coating, the incubation layer of planting, draining water conservation layer three part.Dry density is at 120kg/m
3, wet density 450～650 kg/m
3between.There is effects such as not destroying natural resource, sanitary cleaning, lightweight, protection of the environment.
For preventing that root system of plant from wearing out building waterproof layer, should select the plant of fibrous root prosperity, avoid selecting system of taproot plant or the stronger plant of root system puncture.
Select easily transplantings, resistance to pruning, resistance to low level management, poky plant, avoid live load that plant strengthens year by year on building the impact of dead load.Select the landscape plant of wind resistance, drought-enduring, resistance to summer high temperature.Selection has resistance to air pollution, can absorb the plant of pernicious gas entrapment of contaminants matter.Roof greening can be according to different plants to the requirement of planting matrix soil thickness, arbor, shrub is set to planting in pond or in greenery patches, carries out local mima type microrelief processing.
