Abstract

The utility model provides a light-duty greening roof which is water-saving, fertilizer-preserving and waterproof for long term. The light-duty greening roof comprises a building roofing layer. A root-separating water-resistant moisture-preserving composite layer, a substrate layer and a vegetable layer are laid upward on the building roofing layer in sequence. The root-separating water-resistant moisture-preserving composite layer is formed by superimposition of an upper layer of geotextile, a lower layer of geotextile and a middle layer of HDPE (high-density polyethylene) geomembrane. The substrate layer adopts a special growth substrate for greening of a light-duty roof which is treated by technologies such as slow release of fertilizers, insect prevention, disease prevention and moisture preservation, and sedum lineare seedling blocks (or other crassulacean plants such as sedum sarmentosum, sedum kamtschaticum and the like) with one-time lawn formation are paved and planted on the substrate layer. The light-duty greening roof leads the light-duty roof greening technology to realize simple and convenient technique and low cost, and simultaneously can save water and preserve fertilizer for long term; and in addition, the materials are not fixed with a building roof, the movement is easy and the disassembly is flexible, and therefore, the light-duty greening roof provides a new greening technology applied in various new and old building roofs.

Description

A kind of light-duty greening roof

Technical field

The utility model relates to greening technology, specifically, relates to a kind of long-acting water saving, protects light-duty greening roof fertile, waterproof.

Background technology

Roof greening mainly contains dual mode, and a kind of is compound, and another kind is a skeleton symbol.Double roof greening has only the only a few roof to adopt this greening mode because all higher to built-loading requirement and construction and later maintenance cost.At present most widely used is the skeleton symbol roof greening.

But it is that basic unit is thinner that skeleton symbol is afforested ubiquitous problem, can not keep water, fertilizer effectively, need often water, supplementary fertilizer, and the measure that do not block water, the roof is prone to drainage.When repairing roof membrane, normally fixing because of greening material therefor and building roof, be not easy to move or dismantle.Therefore, develop long-acting water saving, protect light-duty greening roof and easily detachable roofing thing fertile, waterproof and become problem demanding prompt solution.

Summary of the invention

The purpose of this utility model provides a kind of long-acting water saving, protects light-duty greening roof fertile, waterproof, makes light-duty roof greening realize that technology is easy, cheap.

Another purpose of the present utility model provides a kind of easily detachable roofing thing, and it can either long-actingly be economized on water, protect fertilizer and be easy to again move simultaneously, and dismounting flexibly.

In order to realize the purpose of this utility model, a kind of light-duty greening of the present utility model roof comprises the building roof layer, on described building roof layer, upwards is equipped with successively every root composite bed, hypothallus and the vegetable layer of preserving moisture that block water.

Aforesaid blocking water every root preserved moisture composite bed from the bottom to top successively by 80-600g/m ²Geotextiles, 0.3-1.5 millimeters thick HDPE geomembrane and 80-600g/m with root-resistant puncturing function ²Geotextiles is formed by stacking.

Aforesaid blocking water every root preserved moisture composite bed from the bottom to top successively by 80g/m ²Geotextiles, 0.6 millimeters thick HDPE geomembrane and 500g/m ²Geotextiles is formed by stacking.

Aforesaid hypothallus is light-duty roof greening dedicated substrate layer, and described hypothallus contains the smart powder of rural area soil, turfy soil, crude fibre humus and fertilizer, and thickness is 4-6 centimetre.

Aforesaid hypothallus also contains pesticide, bactericide, water-loss reducer and fertility sustained release agent.It is by with rural area soil, turfy soil, crude fibre humus and the smart powder of fertilizer etc. by 2: 3: 4: 1 weight ratio is mixed, then pesticide, bactericide, water-loss reducer and fertility sustained release agent are mixed by following consumption and matrix, wherein said pesticide is dead for smelling, every cubic metre of consumption 2-4g; Bactericide is for disliking mould spirit, every cubic metre of consumption 0.5-1g; Water-loss reducer is for liking gloomy water-loss reducer, every cubic metre of consumption 2-4g; The fertility sustained release agent can rich long-acting slow-release compound fertilizers for executing, every cubic metre of consumption 30-50g.Laying depth is about 4-6 centimetre, and every square metre of full water weight is less than 40kg.

Aforesaid vegetable layer can be planted the Crassulaceae plant, as stonecrop, stringy stonecrop, take dish etc., be preferably one-stage lawn formation stonecrop seedling piece layer, it is to adopt the process introduction and acclimatization, the Crassulaceae stonecrop that can adapt to the roof adverse weather condition specially is as green plants, utilize its meat, short and small, numerous from being conigenous, extremely drought-enduring cold-resistant barren-resistant, winter, green subtracted light and not dead, spring is returned green again, water saving, the saving of labor is hardly with the characteristic of managing, host material with the 2-3 cm thick is cultivated the lawn piece in special planting base, once sod into the level ground on the roof, easy construction, it is green to realize that rapidly the roof covers.

The utility model also provides a kind of roofing thing, this roofing thing comprise upwards stack successively every root composite bed, hypothallus and the vegetable layer of preserving moisture that block water.

It is thinner that advantage of the present utility model has been successfully to solve the basic unit that the skeleton symbol roof greening exists, and can not keep water, fertilizer effectively, do not have the measure that blocks water, and roof problem such as easily leak is developed long-acting water saving, protected light-duty greening roof fertile, waterproof; In addition, the utility model material therefor is not all fixed with building roof, is easy to move, and dismounting flexibly can be specifically applied to the greening new technology on all kinds of new, old building roofs.

Description of drawings

Fig. 1 is the long-acting water saving of the utility model, protects the light-duty greening roof construction figure of fertilizer, waterproof, and wherein, 1 is the building roof layer, and 2 are the composite bed of preserving moisture that blocks water every root, and 3 is hypothallus, and 4 is vegetable layer.

The specific embodiment
