The lawn pad of the solid soil of ecological revetment
Technical field
The utility model relates to the technical field of the vegetation slope pavement in a kind of restoration of the ecosystem engineering, the lawn pad of the solid soil of specifically a kind of ecological revetment.
Background technology
Side slope behind the excavation, because destruction and the current scour of vegetation cause the soil erosion and soil erosion, ecological environment is destroyed around making, need take the solid soil of artificial measures's bank protection to repair.The recovery of vegetation needs the time for many years usually, and when early stage, plant was immature, root system was flourishing inadequately, requires slop protection material to have solid preferably native effect to support the growth of plant; The later stage of recovering; it is flourishing that vegetation root system becomes; plant itself has the solid native ability of very strong bank protection; this moment, the solid native effect to slop protection material there is no much requirements; consider from the aspect of preserving the ecological environment; to the requirement of slop protection material is can natural degradation, perhaps preferably changes into the nutrient of plant growing.
Usually adopted the mode of stone masonry bank protection and dirt bank protection, but stone masonry and dirt are not supported plant growing in the past, adopt above-mentioned dual mode can't plant plant, in addition cost height, environmental protection inadequately yet.At present geotechnical grid grassed slope method and geotechnological gauze pad grassed slope methods used more, though these two kinds of methods are all supported the growth of plant, but still there is following problem: first, because geotechnological material is the high molecular polymer product, be difficult to corrosion, can't natural degradation, thereby adopt this method, when administering side slope, also can cause the pollution once more of environment; The second, when geotechnical grid grassed slope method and geotechnological gauze pad grassed slope method are constructed at the scene, adopt the mode of mud jetting to sow seeds, need to use spray seeder, and spray seeder price height, a price is about more than tens0000 yuan, adopts the slope treatment cost of these two kinds of methods very high.
Summary of the invention
The purpose of this utility model is in order to remedy the deficiencies in the prior art, and the lawn pad of the good solid soil of ecological revetment of a kind of simple in structure, with low cost, environmental protection and bank protection performance is provided for people.
The purpose of this utility model realizes by following technology side.
The lawn pad of the solid soil of a kind of ecological revetment is characterized in that being formed by string and the stranded braiding of fibers material, is latticed.
Described string is brown fiber, coconut husk silk or flaxen fiber.
Described fibers material can be glass, synthetic fibers such as polyethylene, polypropylene, polyvinyl chloride or nylon yarn etc., also can use the plastics feed back.
The thickness of described lawn pad is 1cm ~ 5cm, and fabric width is 50cm ~ 100cm, and the grid aperture is 1 cm * 1 cm ~ 5 cm * 5 cm.
Lawn of the present utility model pad is a primary raw material with the string of natural material, adds a certain proportion of have certain intensity, corrosion resistant fibers material simultaneously, through stranded formation fiber bundle, is woven into the Gitterfasern fabric.When early stage, plant was immature, the lawn pad can be alleviated rainwater to the washing away of domatic soil, and has water storage function, plays the effect of soil and slope protection.After 1 ~ 2 year, vegetation recovers substantially, and it is flourishing that root system becomes, and vegetation itself has had very strong bank protection ability.In this stage, the string in the pad of lawn rots, and forms organic humus, becomes the required nutrient of plant growing simultaneously.
The lawn pad manufacturing process of this utility model is simple, and cost is low.During engineering was used, this lawn pad laying method was simple, flexible.The area size of whole lawn pad can design arbitrarily, can freely adjust according to natural topography and geomorphology when construction is used, and cuts out suitable dimensions and gets final product.

Fig. 2 is the structural representation of single litzendraht wire of the present utility model;
Fig. 3 is the schematic diagram that the utility model uses at engineering site.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
As depicted in figs. 1 and 2, lawn of the present utility model pad is latticed, form by coir fibre and stranded fiber bundle 1 braiding of plastic products feed back fiber, wherein the ratio of coir fibre and plastic products feed back fiber is 2:1, and the litzendraht wire of lawn pad is by two strands of coir fibres 3 and one plastic products feed back fiber 4 stranded forming.The thickness of this lawn pad can be set to 2cm according to the place needs, and mesh 2 is of a size of 1 cm * 1 cm, and making fabric width usually is 1m, length 50m.During place mat, can be cut into suitable dimensions according to the topography and geomorphology in place.
As shown in Figure 3, during constructing at the scene, can lay like this utility model: lower floor's lawn pad 5 is imbedded in the former ground surface soil 6 (promptly main soil), and loose ground surface soil made real, lay the seed plant growth substrate 7 (being soil moved in to improve the original) that one deck is mixed with water-loss reducer on it, re-lay lawn, upper strata pad 5 on the soil moved in to improve the original and make real.With bamboo wooden peg 8 serial connections, the bamboo wooden peg inserts in the former ground surface soil, fixes with the face of land between the pad of two-layer up and down lawn.Usually the lawn pad is wide is 1m, and the bamboo wooden peg is spaced apart 1m in the width setting.The different lawn chock system nail of width is provided with at interval also can correspondingly be adjusted.
