Abstract

The invention discloses a technical method of a green sponge roof modified on basis of a grass planting plate. The method comprises the following steps: laying a waterproof material on a roof; laying a root isolation material on the waterproof material; then laying an ecological grass planting plate, and laying an isolation filter material on a water drainage-storage water layer; burying planting soil on a filter layer; and seeding herbaceous plant seeds in the planting soil above the grass planting plate, watering, maintaining, completing the roof vegetation after an ecological colony is formed by herbaceous plants, and forming the green roof. The green roof technique is simple in construction process and easy in operation; the grass planting plate is used as the water drainage-storage layer and the plant planting basic surface, so that compared with the traditional green roof method adopting a coarse sand filter layer and a gravel (cobble and ceramic particles) drainage layer, the construction difficulty is much smaller, the construction stability is high, the construction quality and effect can be guaranteed, and the formed landscape is ecological and attractive.

Description

A kind of technical method on green sponge roof based on grass planting plane transformation
Technical field
The present invention relates to the technical method on a kind of green sponge roof based on grass planting plane transformation, belong to Green Roof technical field.
Background technology
Present stage Chinese Urbanization is constantly accelerated, and occurs in that large-area waterproof ground and roofing, thus results in the ecological environment problems such as urban heat island, shortage of water resources, water pollution.For protection improvement of environment weather, Green Roof increasingly comes into one's own.But the discharge structure layer that oozes of traditional Green Roof is made up of coarse sand filtering layer, gravel (cobble, haydite) drainage blanket, its shortcoming is big except quantities, construction time is long, labour cost is big with freight, the most this structure only has drain function, do not have water storage function, the water yield easily to scatter and disappear, cause the waste of water resource.
Owing to building structure bearing capacity directly affects the height of cost of a building, therefore the permission load of the unit are on roof is all restricted, so the thickness that roof greening plants soil is limited to the bearing capacity of building and slab column and the bearing capacity of basic foundation.Relatively thin planting soil, without rainwater or equilibrium manual watering, then soil is dried the most rapidly, unfavorable to growth and development of plants.
The work progress of roof greening is carried out in high-altitude substantially, and materials handling cost is more much higher than ground, meanwhile, impermeable, base is native, irrigate and all can increase construction cost with the aspect such as drainage system.Secondly, in terms of the maintenance management after building up, roof greening maintenance cost is more much higher than common Green Space Construction.
Summary of the invention
The goal of the invention of the present invention is to provide a kind of technical method on green sponge roof based on grass planting plane transformation, solves the relevant issues such as existing roof greening is waterproof, draining, loading, and improves water utilization rate.
To achieve the above object of the invention, the technical solution used in the present invention is: the technical method on a kind of green sponge roof based on grass planting plane transformation, comprises the steps:
(1) at roofing waterproof material, waterproof layer is formed;
(2) lay on waterproof layer every root timber material, formed every root layer, be used for preventing root system of plant from penetrating waterproof layer;
(3) the most laid grass planting plane, forms water draining and accumulating layer, then lays isolation filtering material on described water draining and accumulating layer, form filter course;
(4) on described filter course, bury planting soil, form hypothallus;
(5) being sowed by herbaceous plant seeds in the planting soil above grass planting plane, process is watered, maintenance, treats that herbaceous plant forms self ecological community and i.e. completes roof greening, forms Green Roof;
The bottom of wherein said grass planting plane is full-closed structure, and the bottom of described grass planting plane is additionally provided with the spike supporting grass planting plane, and the upper end of described grass planting plane is additionally provided with the gap for spilling water.
Preferably, the thickness of described hypothallus is 7~13cm, and thickness is determined according to roofing bearing capacity and vegetation type.
Preferably, described planting soil includes soil, and in described soil, the proportioning of leaf mould, Vermiculitum and sandy soil is 7:2:1.
Preferably, the cross section of each grid of described grass planting plane is six prism structures, and the upper end of each side of described grid is equipped with gap.
Preferably, one or more in root timber material is alloy, rubber, PE or HDPE described.
Preferably, described isolation filtering material is the most permeable but also filtrable polyester fiber non-woven fabric.
Preferably, the wet density of described planting soil is 1.2~1.5 with the ratio of dry density.
Preferably, described waterproof material is self-adhesive rubber asphalt waterproofing coiled material.
Preferably, the height of described grass planting plane is 7cm.
Above, the root growth of plant is the deepest, and the thickness of required soil is the thickest, and the load load-bearing on i.e. required roof is the biggest, relatively big at building roof wind-force, sunshine is relatively strong, and the soil matrix of the plant growing ratio that naturally runs off is more serious.Therefore should select can Radix Saposhnikoviae, anti-day be bright, cold-proof, the plant of shallow root;Herbaceous plant is watered, maintenance time, depending on the rainfall to be regarded that waters, be preferably and water every day to be kept when not raining, when rate of vegetation reaches 90%, be gradually lowered irrigation amount as the case may be;After herbaceous plant self forms stable vegetation structure, i.e. complete the process of roof greening, now need not maintenance special to plant.
Above, having gap between the spike of grass planting plane, form drainage blanket, the water of spilling can flow out from gap.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
1. this technology uses ecological grass planting plane to replace the adrainage material of common Green Roof simple function, has not only acted as drainage, it is often more important that can play the function of rainwater harvest as sponge;
2. this Green Roof technique building technology is simple, easily operated, by grass planting plane as water draining and accumulating layer and the basal plane of plant growing, compare the coarse sand filtering layer on conventional green roof, the way of gravel (cobble, haydite) drainage blanket, difficulty of construction is much smaller, construction stability is high, so that it is guaranteed that last construction quality and effect, the view formed is not only ecological but also attractive in appearance;
3. the Green Roof construction method construction costs of the present invention, construction cost are low, only need common ecological grass planting plane, decrease the destruction to environment of the building waste in work progress;
4. the present invention compares with traditional Green Roof way, not only reduces drainage blanket thickness, alleviates roof load, and sound construction, low cost, environmental protection, and attractive in appearance.
