Abstract
A water storage and drainage member of a planting top plate comprises a protective insulation layer, an upper waterproof layer, a lower waterproof layer, a convex-concave water drainage plate and a filtering layer. The water storage and drainage member is characterized in that the lower waterproof layer and the upper waterproof layer preventing roots from piercing are arranged above the protective insulation layer, the convex-concave water drainage plate is arranged above the upper waterproof layer, and the filtering layer is arranged above the convex-concave water drainage plate. The water storage and drainage member has the advantages that a hollow vertical rib structure arranged in the convex-concave water drainage plate can guide rainwater out rapidly and effectively, hydrostatic pressure of the waterproof layers is reduced or even eliminated, and waterproof effect is achieved by means of the active water diversion mode. The water storage and drainage member of the planting top plate has a 50-percent water storage function while draining water, ensures enough water required by plant growth, enables root systems to grow downwards rapidly to be rooted in soil firmly, and has the advantages of being light in weight and capable of reducing cost, firming roots, achieving ventilation and providing enough water and air to ensure smooth growth of plants.
Description
Technical field
the utility model relates to roof greening, water discharge technology field, particularly a kind of plantation top board drainage member.
Background technology
draining is the key technology of plantation top board engineering, and draining is good and bad is the outstanding difference in roof greening and gardens, ground, is that roof can or can not leak, and roof moving load can or can not exceed standard, and can root system of plant have the large problem of good breathing.Draining processing is all paid close attention in the always construction of roof garden, traditional method mostly adopts and on waterproofing course, lays block layer, lay again dander or boulder bed in the above, object is all the draining that keeps good, at present roof greening drainage blanket is mainly to lay band drain, or lay cobble, haydite etc. at edge; Traditional handicraft is simple draining and there is no water storage function, need a large amount of waters to carry out routine servicing, first caused a large amount of water resource waste, because surface water is more than underground water, the root system of plant is upwards grown and is made plant cannot consolidate root to cause plant body of one who has dropped dead by the roadside dead, more unfavorable to macrophyte growth.The soil property that simultaneously makes planted roof select has produced very large difficulty.Because select drainage, soil property that gas permeability is strong can make water resource preserve, if select the former planting soil again can be because gas permeability is poor, the generation phenomenon that hardens, make plant death, secondly traditional handicraft will fully take into account the growing state of root system, and the planting soil thickness of selecting reaches 180-150cm, surface water enters underground time that need to be longer, rainy day water is large, anxious in the situation that, the discharge of surface water has very large difficulty, must build gutter with a large amount of financial resources manpowers could solve; Hold heat-extraction system so carry out plantation top board, for saving water resource, reduce irrigation cost and building costs, improve plant survival rate and all there is very strong realistic meaning.
Summary of the invention
the purpose of this utility model is to provide a kind of draining rapidly, can not form ponding on roofing, is conducive to plant growth, and drainage blanket thickness and weight are little, have alleviated the load of roofing; Effectively waterproof and the prolongation waterproofing course plantation top board drainage member in application life.
the utility model is achieved in that it comprises protection insulation layer, upper waterproofing course, lower waterproofing course, convex-concave band drain and filtration beds; it is characterized in that being provided with in protection the upper waterproofing course that lower waterproofing course and root thorn prevention are worn above insulation layer; above upper waterproofing course, be provided with convex-concave band drain, above convex-concave band drain, be provided with filtration beds.
the utility model has the advantages that the hollow stud structure being provided with in convex-concave band drain can derive rainwater fast and effectively, reduce the hydrostatic pressing of even eliminating waterproofing course, reach the effect of waterproof by the mode of this active water guide, plantation top board drainage member also has 50% water storage function in draining, can guarantee the enough moisture that plant growth is required, also make root system take root fast downwards, firmly take root in soil.Also there is quality light, cost-saving, solid root, ventilative, and have again sufficient water, gas to guarantee the advantage of plant smooth growth.
accompanying drawing explanation:
below in conjunction with accompanying drawing, the utility model is further described;
fig. 1 is the structural representation of plantation top board drainage member,
fig. 2 is the structural representation of convex-concave band drain.
The specific embodiment
as shown in Figure 1; this plantation top board drainage member comprises protection insulation layer 1, lower waterproofing course 2, upper waterproofing course 3, convex-concave band drain 4 and filtration beds 5; above protection insulation layer 1, be provided with the upper waterproofing course 3 that lower waterproofing course 2 and root thorn prevention are worn; above upper waterproofing course 3, be provided with convex-concave band drain 4; above convex-concave band drain 4, be provided with filtration beds 5; convex-concave band drain 4 comprises groove 6 and boss 7; the height of the groove 6 of convex-concave band drain 4 is 12.5mm, and the height of boss 7 is 12.5mm.
Claims (2)
1. a plantation top board drainage member; it comprises protection insulation layer, upper waterproofing course, lower waterproofing course, convex-concave band drain and filtration beds; it is characterized in that being provided with in protection the upper waterproofing course that lower waterproofing course and root thorn prevention are worn above insulation layer; above upper waterproofing course, be provided with convex-concave band drain, above convex-concave band drain, be provided with filtration beds.
2. Ju plantation top board claimed in claim 1 drainage member, is characterized in that convex-concave band drain comprises groove and boss, and the groove height of convex-concave band drain is 12.5mm, and boss height is 12.5mm.
