Description
Technical field
The present invention relates to a kind of water-keeping material for afforesting, for roof wall surface greening or wall greening plant growing.
Background technology
The greening of existing roof wall surface mainly uses light-weight soils, and it is limited for reducing weight.In order to popularize roof wall surface greening, because the load on roof is limited, it is therefore necessary to reduce weight further；Using the cultural method of the thin layer lower vegetation of soil, the lightweight of roof wall surface greening is also possibly realized；But, the problem that water holding capacity difference occurs because of soil making consumption few in thin layer lower vegetation；Therefore, the substrate water-keeping material of exploitation light weight, can effectively keep rainwater is very important thing.
Existing substrate water-keeping material, uses and weaves cotton cloth and polyurethane foam analog etc..It addition, at the pallet that expanded polystyrene (EPS) is provided below of thin layer plant, store with this and provide water.But, these material costs are high, it is necessary to more cheap water-keeping material.Additionally, these material sources are in oil, and the water-keeping material of roof wall surface greening is to improve urban environment as target, and the material therefore using non-petroleum sources is very important.It addition, when wall greening, the root of rattan property plant enters metope and prevents coming off of plant from being highly important, but, does not account for this performance in existing wall greening material.
Summary of the invention
The purpose of the present invention is to propose to a kind of water-keeping material for afforesting and tectosome, the roof wall surface greening method of exploitation light weight, with wood fibre board as water-keeping material, solve the resistance to load limit of fabrication.
The technical solution of the present invention: for the water-keeping material afforested, including
(1) it is the wood fibre board of primary raw material with lumber fibre, is pressed into phenolic resin heat, to improve durability；
(2) wood fibre board adds surfactant, to improve the water-retaining property of the water-keeping material of plant culture；
(3) wood fiberboard facilitates plant root whisker embed, reduce the consumption that makes of soil, form the light weight greening tectosome of the low dwarf plant of thin layer；
(4) water absorbent polymer is contained in wood fibre board, to improve water-retaining property；
(5) fertilizer is contained in wood fibre board, promotes plant culture.
Advantages of the present invention:
1) constructing according to this greening, roof wall surface greening becomes easy, and urban afforestation is also promoted, and particularly this greening tectosome is very light, and the roof wall surface green quilt of existing structure is popularized；
2) present invention can advance urban afforestation, it helps slows down heat island phenomenon, advances roof wall surface greening in factory, and summer, the temperature of inside plants can reduce；
3) wood fibre board used is made up of lumber fibre as water-keeping material, so can obtain raw material from wooden garbage, has therefore also effectively recycled timber；
4) using water-keeping material to carry out roof wall surface greening, effectively stored by rainwater, therefore urban afforestation can effectively utilize rainwater, stores rainwater；
5) greening enforced concrete structure is in thin layer lower vegetation, do not need the cultural method of soil and cultivation tray, the fiber of wood fibre board and the root of plant can merge mutually, because it does not use soil, lightweight, assemble easy for installation, so the plant culture basis as roof wall surface greening is best suited for；
6) painting activating agent in wood fibre board surface can improve absorption speed and reservoir storage.
Accompanying drawing explanation
Fig. 1 is the profile of greening tectosome.
In figure 1 is greening tectosome, 2 to be wood fiberboard, 2-1 be is not impregnated with the wood fiberboard of interfacial agent, 2-2 is thin layer lower vegetation root mixed growth part, 3 be thin layer lower vegetation.
Detailed description of the invention
For the water-keeping material afforested, including
