Fastening devices in order to the vegetation pad of protecting river levee and slope

Technical field

The present invention relates to a kind of in order to protect vegetation pad and the fastening devices thereof of river levee and slope; be specifically related to a kind of take following content as feature in order to protect vegetation pad and the fastening devices thereof of river levee and slope; it is characterized in that: be arranged on slope, cutting ground or the slope in river course and prevent from coming down and when effectively forming the riverbank vegetation, make slope and additional structure thing be integral structure and promote the germination of vegetation seed or the survival of taking root of vegetation class vegetation pad to realize as early as possible afforesting purpose.

Background technology

In recent years, along with the soil utilization of river basin increases gradually, urbanization progressively develops, and the rivers and creeks environment has brought significant variation.The rectification river environment mode that adopts when improving river environment be harness the river, the extensive civil engineering of water conservancy is main carrying out.So the vicious circle that has brought environment has also further reduced the function of the peculiar natural environment that rivers and creeks itself has.

And, except river water quality pollutes, consist of the river vegetation of ecosystem constituent element and inhabit the fish in river and the population density of birds reduces, had a strong impact on the diversity of perching animal, the function that weak ecosystem habitat should be played.

The high urban river of river periphery land use intensity is in order to reach flood control and flood fighting purpose, by cleaning retaining channel and riverbank, rectification river course, build the mode such as river levee and changed river environment, and built up cement dyke at retaining channel river levee.

For example, cement dyke has cut off river from physical angle and has been penetrated into soil horizon, has hindered natural river river bank moisture loving plant absorption moisture, and the sunshade condition that the river bank vegetation is provided is all gone.This has strengthened the water temperature variation, the river has been lost in order to perch biological in water and fish provide the habitat and the function on the ground of laying eggs, and has also destroyed near the basis of perching of obtaining food vegetation by the river and relying the birds that survive in the vegetation vegetation.

In addition, implement the earth dam that produces after civil engineering or shovel soil or the regional slope that bankets need to be planted vegetation and be afforested to prevent the soil erosion that rainwater brings with waiting cuttings.

Generally, main employing will grow up to the lawn job practices that to a certain degree turfgrass directly covers slope.This job practices need to obtain from the field turfgrass or artificial cultivation turfgrass in advance, has a lot of difficulty aspect turfgrass obtaining.Meanwhile, also can destroy natural environment, need to drop into a lot of manpowers and time during construction, drop into too much.

In order to address the above problem, prior art sprays at slope the adhesive that mixes the vegetation seed germinates and the grass planting construction technology of sowing grass seeds by duster of realization greening the vegetation seed.This construction technology prevents moisture evaporation and stratification at the slope of spray adhesive cover lid again, and rots after germinateing and vegetation growth desired nutritional composition is provided.

, only the sow grass seeds by duster seed mixture and with the strip cropping turfgrass of grass planting construction technology of sowing grass seeds by duster.Therefore, want to cover fully, need 4 to 6 years, also do not possess the domatic any auxiliary material of protection.During Flooding, due to the impact that is subject to flood, river levee can be collapsed or be destroyed.

And, for lid being close to the slope of the adhesive that has hardened, need to utilize the fixedly stake (iron plate anchor) that is formed by steel or plastic material to be fixed.Penetrate when not being close to ground through long-time and implanted draft class root under the state of slope at fixing stake, fixedly the disengaging of stake can destroy the part of implanted vegetation pad.

In addition, as mentioned above, since 20th century, the highway that increase in order to construct day by day flourishing along with means of conveyance in the part of massif or during the local Construction Highway in river, river etc., forms cutting ground in the marginal portion of highway.

Played unpredictable heavy rain under the impact of above-mentioned cutting ground due to the Abnormal Temperature that is subject to the areas such as EI Nino, La Nina, cause 70～80% cutting ground to gutter down moisture, also do not have enough time the moisture penetration that gutters down among the stratum and penetrate into highway or cut the soft part of soil property in ground.

Through said process, in the time of among the excessive infiltration of moisture stratum, cutting ground slope is collapsed or damaged.Slope collapses and can cause vehicle to be buried or when disturbing accident, can stop vehicle pass-through, on human life or property, all can bring huge loss.

The soil property on above-mentioned cutting ground is rock or the sandy soil of chiseling.To be rock form through for a long time physical chemistry effect and biology weathering the earth that consists of most of sandy soil.

And, comprise the organic matter that forms as the mineral of rock decay product with from vegeto-animal remains and the water that forms, carbon dioxide, oxygen etc. from the main composition factor of the earth of rock formation the process of decomposing organic matter.

Therefore, be the cutting of massif or rivers etc. that construction afterwards can be for the soil property of plant growth through approximately just becoming due to the biology weathering of soil property in 5 to 10 years with implementing cutting.

Even also do not destroyed in order to make above-mentioned cutting ground run into the heavy rain in rainy season and brash etc., can turf plant grass, the ornamental plant such as shrub and implement that slope is not collapsed or is not destroyed with afforesting to guarantee cutting.

Above-mentioned cutting ground slope greening construction technique cutting ground slope implement to banket and the seed of seeding lawn grass, shrub plant after, the heat insulating material such as mulching straw, reticulate body and keep humidity, thereby the seed of germination is grown up, in cutting ground slope realization greening.

, above-mentioned cutting ground slope greening construction technique is the technical scheme that scatters seeds and seed is grown up.At this moment, when the slope of the slope part that does not also have enough time to take root or geology aspect drawback partly runs into heavy rain or brash etc., may rush pick cutting ground slope and cause collapsing or destroying.

In addition, cutting ground can be divided into thin native rock (decayed rock), soft rock, admant etc. according to its soil property.When dredging native rock and admant, after implementing cutting ground construction, the compost that gauze wire cloth or reticulate body etc. is set and bankets and formed by sewage sludge, food mud, trade waste, mud, mud etc. at cutting ground slope, after gauze wire cloth or reticulate body are set, the vegetation seed is seeded in above it and implements greening.

In order to secure the above gauze wire cloth or reticulate body, utilize the fixedly stake (the anchor tip) that is formed by steel or plastic material to be fixed., fixedly the stake state that penetrates slope is through for a long time the time, and due to the weathering on ground and the temperature difference for many years, the bottom surface of bound fraction can be become flexible, and causing fixedly, stake breaks away from.At this moment, the soil erosion meeting that brings of heavy rain or the temperature difference causes fastening devices to break away from.

And, after the civil engineerings such as enforcement cutting tip massif, need its appropriate section of greening.The greening of cutting tip has very important significance from preventing floods or placing the aspect, landslide.Up to now, proposed numerous proposals for above-mentioned greening structure, can the most significant drawback be, implemented civil engineering slope afterwards and can not further firmly support greening structure.That is, when heavy rain is attacked, many times afforest in whole or in part part washed away, in fact, do not possess reliability for greening operation itself.
