Abstract
The invention provides a breathable seepage-proofing blanket. The breathable seepage-proofing blanket is of a two-layer structure, the bottommost layer is a piece of geotechnical cloth or geomembrane, and a layer of mixture of binder and sand is located on the geotechnical cloth or the geomembrane. The breathable seepage-proofing blanket has the advantage of preventing water seepage. Besides, the breathable seepage-proofing blanket is provided with nutrients needed by plants and fertilizers needed by the plants, water and the nutrients can be supplied in a certain period of time after the plants are grown, the survival rate of the plants in saline and alkaline land and the sand is increased, and long-term benefits of comprehensive treatment of saline and alkaline land are guaranteed effectively. The breathable seepage-proofing blanket can also be used for afforesting the tops of buildings in a city, improve the afforesting effect and level, and provide reliable technical bases and practical method for comprehensive treatment of environment.
Description
Technical field
The invention belongs to ecotope and repair field, be specifically related to a kind of a kind of flexible apparatus that can play infiltration permeation functions.
Background technology
Cultivated plant, greening environment are the effective means that the mankind improve life condition.Desertization and saline Land cause environmental deterioration.The maximum difficulty of afforestation desert or saline land is that this earth's surface can not conserve water and soil, and does not have nutrient, makes the plant of plantation can not get moisture and nutrition, be difficult to survive.Although all will water after cultivated plant, in desert region, after watering, moisture can ooze rapidly, and the root system of seedling is undeveloped, can not penetrate in very dark soil and absorb moisture; And labor intensive material resources of repeatedly watering are huge.Therefore at drought, precipitation is rare, and the area that vegetation coverage is low, plant is fewer and feweri, land deterioration.
In order to improve the efficiency of desert afforestation, the efficient irrigation technique of software engineering researchers invent all over the world, such as drip irrigation; Or prepare water-storage material with hydrophilic compounds; Or exploitation seepage control technique prevents moisture and nutrient loss.Such as, patent CN201957525U proposes a kind of water proof and to block water percolator, original sand bed is provided with the impervious barrier that blocks water, above the impervious barrier that blocks water, is provided with sand bed, be provided with growing nutrient layer above sand bed, arrange straw plaited clathrum above growing nutrient layer.This device all needed artificial setting before each plantation, and complicated operation and performance can not be consistent.Patent application CN1782237 is also the separation layer arranging antiseepage water conservation before cultivated plant on soil.Not only complicated operation, and the nutrient simultaneously not providing plant growth to need and fertilizer.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of ventilation anti-seepage blanket.
The technical scheme realizing above-mentioned purpose of the present invention is:
A kind of ventilation anti-seepage blanket, described ventilation anti-seepage blanket is double-layer structure, and bottom one deck is geotextiles or geomembrane, geotextiles or geomembrane is the mixture of a layer binder and sand.
Wherein, the particle diameter of described sand is 100-200 order.
Wherein, described adhesive is polyurethane or thermoplastic elastomer (TPE), and described thermoplastic elastomer (TPE) is styrene analog thermoplastic elastomer (SBC triblock copolymer); Polyolefins thermoplastic elastomer, be selected from polyamide-type thermoplastic's elastomer, Ben Yi Xi ?Ding bis-Xi ?styrene block copolymer (SBS), Ben Yi Xi ?Yi Wu bis-Xi ?one in styrene block copolymer (SIS).
Wherein, the thickness of described sand layer is 1-3mm.
Described ventilation anti-seepage blanket preparation method is: adhesive coating in geotextiles or geomembrane, and adhesive coated thickness is 0.1-0.5mm; Then sand is spread, natural seasoning 18-30h.
The application of ventilation anti-seepage blanket of the present invention in afforestation desert or saline land.
Described application digs flat hole or ditch on earth's surface, is laid on by described ventilation anti-seepage blanket in hole or in ditch, then on ventilation anti-seepage blanket, places plant seed, then put into soil.
In order to improve the survival rate of plant, be laid on by described ventilation anti-seepage blanket after cheating in interior or ditch, the side being also included in hole or ditch arranges the step of plastic foil.
Beneficial effect of the present invention is:
The ventilation anti-seepage blanket that the present invention proposes has the advantage preventing moisture penetration, and configure nutrient and the fertilizer of plant needs, moisture and nutrition can be provided in regular period after plant cultivating, improve the survival rate of plant at saline land or sand ground, effectively ensure that the long-term benefit of the saline land comprehensive regulation.The ventilation anti-seepage blanket that the present invention proposes also may be used for the greening at urban architecture top, improves afforestation effect and level, for comprehensive regulation environment provides reliable technical basis and practical method.
Accompanying drawing explanation
Fig. 1 is the structure chart of ventilation anti-seepage blanket.In figure, 1 is geotextiles, and 2 is binding agent and sand mixture.
Embodiment
Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.Without departing from the spirit and substance of the case in the present invention, the amendment do the inventive method, step or condition or replacement, all belong to protection scope of the present invention.
If do not specialize, the conventional means that technological means used in embodiment is well known to those skilled in the art.
Embodiment 1
Ventilation anti-seepage blanket structure (Fig. 1): bottom is geotextiles 1, upper strata is sand and binder mixtures 2.Mixture layer thickness 2mm.
Sand is through screening, and to get particle diameter be 100-200 object sand.
Preparation: geotextiles 1 tiles, even coated with adhesive (polyurethane Strong Adhesive, Yantai ten thousand China) 0.1-0.2mm, then sand 1 on uniform spreading, place 24 hours, obtain the product solidified.
Obtained ventilation anti-seepage blanket can curved 120 ° (curved to angle 30 °) continuous, there is good flexibility and good antiseepage function.Because there is geotextiles to be lining, can transport for long-distance, intensity is better.
Embodiment 2
Ventilation anti-seepage blanket structure: bottom is geomembrane, upper strata is sand and binder mixtures 2.Mixture layer thickness 1.5mm.
