Description
Technical field
The utility model belongs to technical field of civil engineering, and in particular to a kind of pressure sand plant protection for arid tract
Bank protection.
Background technology
With the fast development of northwest China arid area infrastructure project construction, the side slope in northwest drought area is a large amount of
Appearance, since arid tract precipitation is less, annual rainfall is about 200~350mm, and is concentrated mainly on June to September, ecology
Fragility, plant survival rate are very low.
Therefore, arid tract side slope protection seldom uses plant protection, such as Baiyin, Dingxi, Lanzhou, in Ningxia
The side slopes such as portion's arid tract highway, railway seldom use plant protection, mostly use mortar flag stone facing wall greatly, skeleton bank protection, mix
Engineering protections measure, these safeguard procedures such as solidifying native prefabricated sash and gunite concrete can reduce slope surface to a certain extent and degrade
With the generation of erosion, protection effect is good, but cost is high, complex process, easily caves in because itself is unstable, most important
It is that periphery natural ecological environment is uncoordinated, influences the landscape in the range of engineering.Vegetation slope pavement have can restore punja band edge
Slope ecology conserves water and soil and prevents erosion, and afforests and beautifies landscape, improves soil environment, enhances slope stability and mitigation
The advantages that soil erosion, the eye strain of elimination driving path person is the effective means for preventing slope geological.
Utility model content
In view of this, the main purpose of the utility model is to provide a kind of soil property abrupt slope pressure sand for arid tract to plant
Object protects bank protection.
In order to achieve the above objectives, the technical solution of the utility model is realized in：
The utility model embodiment provides a kind of pressure sand plant protection bank protection for arid tract, setting slope surface simultaneously
And include shoulder protector, main framing, spats, branch skeleton, the shoulder protector and spats are separately positioned on the top and bottom of slope surface, the shield
It is connected along the main framing that slope surface is arranged by vertical direction between shoulder and spats, the main framing is horizontally spaced to be set successively
Set multiple, the branch skeleton connects multiple main framings in the horizontal direction and the branch skeleton is vertically-spaced sets gradually
It is multiple.
In said program, cellular geotechnological lattice are respectively provided in the region that the multiple main framing and multiple skeletons are formed
Room.
It is uniformly distributed at the lattice section point of the cellular geotechnical grid to have several fixing anchor bars in said program.
In said program, the shoulder protector, main framing, spats, branch skeleton are provided with Sloping Foundation close to the side of slope surface.
In said program, filled with improvement planting soil in the cellular geotechnical grid, and plants and be implanted with drought-enduring plant.
In said program, pressure layer of sand is covered on the improvement planting soil.
Compared with prior art, the utility model makes precipitation penetrate into soil, reduces runoff, and prevents improvement planting soil by sun
Light direct beam can also cut off soil capillary water rising, prevent moisture from distributing outward, reduce moisture evaporation, make drought-hit area side slope soil
Water storage point is protected, in favor of slope green plant growth, improves the survival rate of side slope drought-enduring plant, popularizing application prospect is very wide
It is wealthy.
