Description
Technical field
The utility model is related to protecting slope ecology fields, more particularly to a kind of slope ecological reparation knot of breakage mountain body
Structure.
Background technology
The mankind disorderly cut into a mountain for quarrying for a long time, and large stretch of natural vegetation is destroyed, and massif breakage forms exposed slope surface, warp
Prolonged erosion and weathering are crossed, becomes rock, plant can not be in growing on massif, and such massif is known as breakage mountain body.
The quickening of urban construction step causes the demand of building stone to greatly increase, many surrounding cities mountain that beautiful environment originally
Body becomes stone pit in urban construction, thus a large amount of original massifs are seriously damaged, and cause such as soil erosion, mountain
A series of natural calamities such as body landslide, mud-rock flow, seriously threaten the survival and development of the mankind, it has also become the whole world is faced now
Common issue.The restoration of the ecosystem of breakage mountain body can help improve the ecological environment of breakage mountain body, avoid the exploitation because of massif
It is extremely urgent to find suitable breakage mountain body restoration of the ecosystem measure for the ecological problem and environmental problem for bringing getting worse.
Common breakage mountain body ecological reestablishment includes artificial vegetation, linked network is sowed grass seeds by duster, tape planting is afforested, sash soil moved in improve the original is green
Change, the combination of planting trough and these technologies.Wherein, linked network spray seeding technique is the modern international novel spraying and seeding afforesting side used
Formula, day this application it is very universal, and afforestation effect is preferable.It is by organic soil, depot fertilizer, adhesive, grass-seed etc. by one
Fixed ratio forms and what is stirred evenly has base material, sows grass seeds by duster in the slope surface for hanging with metal mesh or bar-mat reinforcement by specific machinery of sowing grass seeds by duster
On, form the certain thickness planting matrix that can allow plant growth in slope surface.After revegetation, the root system of one side vegetation with
Mesh sheet is woven below, forms the solid protective soil layer with reinforced action, and on the other hand prosperous root system can pass through base material
The section deepened to rock mass buries and in crack, can reach solid slope purpose.
Although linked network spray seeding technique has obtained good application in the engineering practice of nearly more than ten years, in concrete application
In also there is great number of issues, such as：1. for the rock side slope that excessively precipitous or slope surface is more smooth, matrix of sowing grass seeds by duster is difficult to jail
Solid the phenomenon that being attached in slope surface, matrix caused to fall off or be lost in；2. southern area rainy season is longer, rainwater is to matrix punching of sowing grass seeds by duster
Brush is serious, and soil erosion and pollution of area source have been further aggravated instead；3. slope surface is adhered to, the supply of base material fertility is not lasting, and vegetation is easy
It degenerates, be unfavorable for vegetation stablizes growth and the succession of vegetational type；4. uneven due to slope surface, mesh sheet is difficult to slope surface
Good fit influences the growth of later stage slope plants.
Researcher is also made that numerous corrective measures to linked network spray seeding technique at present, such as：Notification number
A kind of planting troughs of CN105178337B are sowed grass seeds by duster the protecting slope ecology method combined with linked network, and this method sprays planting trough and linked network
Ecological protection of the thin combination for side slope, improves the compactness of mesh sheet and slope surface, increases the stability of side slope, however for
Precipitous precipice side slope, and the planting trough of concrete segment shape should not be set, stronger wind-force and rain-impact, it is possible to can make
It falls off at the sliding of planting trough, there are larger security risks after the completion of construction；For another example notification number CN105113518B is a kind of
The protecting slope ecology substrate building method that slope surface is equipped with slot hole is thought, in side slope drilling fixing anchor bar linked network, to prevent concrete
Sheath generates damage, therefore pit slot is excavated in utility model selection, preset concrete sash is placed into pit slot and in sash
Interior planting plants excavate pit slot, the damage of massif will be increased further, and not though this method is not necessarily to bore operation
Conducive to the firm of massif side slope, there are safety risks.
