Abstract
The utility model relates to a protective device for a naked earth surface covering in an urban green land. The protective device is characterized by comprising a protective mesh enclosure and a fixing piece for fixing the protective mesh enclosure, wherein the protective mesh enclosure is formed by processing mesh non-woven fabrics which are produced by polypropylene serving as a raw material in a needle punching process. The protective device is simple in structure, low in cost, convenient to assemble and disassemble and good in fixing effect, and the soft protective enclosure is high in adaptability to plant coverings in different stacking shapes. According to the protective device, the properties of materials are stable, the protective device is pervious to water but not to soil, can prevent dust from being raised and does not influence air permeability, and various water and fertilizer management measures are performed normally. In addition, the protective device has the advantages of ultraviolet (UV) resistance, difficulty in degradation, aging resistance, no toxicity, no combustion supporting and the like, can be recycled within a certain period, and is environment-friendly.
Description
Technical field
The utility model relates in a kind of urban afforestation the improvement of exposed plot surface covering, relates in particular to the protector of exposed increased surface covering in a kind of ecological, environmental protective, the urban green space with low cost.
Background technology
After the urban green space was built up, because the physiological requirements of plant itself or ecological demand are limited by natural conditions perhaps, it was inevitable exposed plot occurring.For example, after urban path tree is planted, generally will stay at butt the open ground (planting pit) of certain area, purpose is that street tree is kept in touch by open ground and external environment, as the communication channel of water, fertilizer, nutrient, thereby improve survival rate and the vitality of trees.Because organic mat does not almost have negative effect to environment, adopt garden plant waste to produce the organic mat product and be widely used abroad, also more and more be subject to professional person's approval in China.At present, in urban landscaping advanced country or city, organic mat has wide range of applications, soil surface covers when can be used for the ornamental plant plantation, table soil covers between flower bed edge and thin planting nursery stock, lawn and flower bed, isolate between lawn and the trees, large tree tree root periphery exposed part covers, the switch transition location covers between the greenery patches, the roof top garden, the multiple occasion such as flower bed, usually lay the ornamental plant covering of 5cm left and right thickness at exposed soil or base material, namely by after plant refuse is pulverized the processing processing, be used for the greenery patches surface coverage, not only can effectively solve airborne dust and water and soil loss problem, and growth and development of plants had good booster action, also be conducive to the recycling of urban afforestation discarded object, promote Sustainable Development of Urban Planting Undertaking.But, the most employing of ornamental plant covering is directly spread and is spread to cover exposed table soil in present practice, so in order to prevent the generation of the phenomenons such as water erosion, wind erosion, require the crushed material can not be very few, meticulous, preferably make the laminated structure of long 3 ~ 10cm, thick 0.5 ~ 1cm.Secondly, very easily broken up by heavy rain when using in domatic greenery patches, thereby affect result of use.In addition, because garden plant waste directly is exposed in the air, also easily grow mosquito.Above-mentioned many unfavorable factors have restricted applying of ornamental plant covering.
Summary of the invention
For the deficiencies in the prior art, the technical problems to be solved in the utility model provide a kind of effective, cost is low, and can not cause the protector of the ornamental plant covering of new environmental problem.
The protector of exposed increased surface covering in a kind of urban green space, it is characterized in that: described device comprises protection net and the fixture that is used for fixing this protection net, and described protection net is to adopt polypropylene to be raw material production, to process through the webbed nonwoven of needling process shape.
Further, an end of described fixture has protuberance, and the other end of fixture has tapered portion, and described protection net is provided with locating hole, and the opening size of this locating hole should make that protuberance can not pass through on the fixture.
Further, described fastener length is more than or equal to 20cm.
Described fixture adopts polypropylene material to make.
The protector that the utility model provides, simple in structure, with low cost, installation, convenient disassembly, good fixing effect, and the cover degree adaptability that soft protection net is stacked shape for difference is stronger.At protection net a plurality of locating holes are set, passing locating hole with fixture can be fixed in protection net on the ground firmly.Size and the shape of using protector of the present utility model to fix exposed earth's surface cover degree in the urban green space no longer include specific (special) requirements, elastic net structure can adapt to the covering of various heap shapes, and no matter is that wind erosion or water erosion problem all can not occur for level land or slope.Secondly, the material character that protector adopts is stable, and is only permeable soil impervious, can prevent airborne dust, also do not affect gas permeability, and various water, fertile control measures are also carried out as usual.And have uvioresistant (UV), be difficult for degraded, anti-aging, nontoxic, the advantage such as not combustion-supporting, recyclable recycling in the some cycles can not cause environmental pollution.In addition, if need to increase landscape effect, can be easily attached subsides or embroider required color or the pattern of shape on protection net, by covering is carried out the method that pigment dyeing strengthens landscape effect, avoid producing pollution problem before needn't adopting again.

Embodiment
For making your auditor and the public can further understand feature of the present utility model and beneficial effect thereof, the spy is described in detail as follows embodiment of the present utility model with embodiment:
The protector that present embodiment provides, be used for the protection, fixing of exposed earth's surface, urban green space cover degree, its protection net 1 and the fixture 2 that is used for fixing this protection net 1, protection net 1 adopts polypropylene to be raw material, to process through the webbed nonwoven of needling process shape, this nonwoven cloth material intensity is high, stable in properties, and anti-uv-ray is strong.Fixture 2 adopts polypropylene material to make.The structure of protection net 1 and fixture 2 respectively as shown in Figure 1 and Figure 2, the length of fixture 2 is generally more than or equal to 20cm, one end of this fixture 2 has protuberance 21, the other end has tapered portion 22, be provided with some locating holes 11 along protection net 1 periphery, the opening size of this locating hole 11 should make that protuberance 21 can not pass through on the fixture 2.
As shown in Figure 3, ground with the upright projection districts of isolated planting trees 3 on the greenery patches is covered as example: at first cover garden plant waste that one deck crushes on the ground of the tree crown upright projections of trees 3 as covering 4, about thickness 8～10cm, but the interior edge of covering 4 is apart from more than the trunk 10cm, covering 4 outer along the line basically with the outer line overlap of tree crown upright projection.Then according to shape and protection net 1 of thickness cutting of covering 4, protection net 1 is correctly covered on the covering 4, covering 4 does not expose the edge of protection net 1, at last the tapered portion 22 of fixture 2 is inserted in the locating hole 11 of protection nets 1 periphery and goed deep into ground, until the protuberance 21 of fixture 2 tightly overlays protection net 1 in ground.
