Description
Technical field
The present invention relates to river channel ecology side slopes and falling zone ecological restoration technical field, and in particular to a kind of river channel ecology bank
Protect system and falling zone Ecosystem restoration system in slope.
Background technology
The natural bank slope of rivers and lakes is susceptible to due to being corroded by rainfall runoff, flow and wave because of water and soil
It is lost in, causes bank slope degeneration, sedimentation, aquatic environment seriously to destroy, especially reservoir area fluctuating zone, erosion condition are more tight
Weight.
Traditional bank slope, which is repaired, generally uses rigidity revetment, such as stone matter masonry, concrete masonry, gabion, soil engineering bag, this
Although a little traditional engineering measures can control the soil erosion to a certain extent, ecological restoration function is not perfect.In bank slope
Or falling zone plantation vegetation carries out water and soil conservation, but often all it is unfavorable for sloping bank life through can't stand current scour and wave erosion
The sustainable differentiation and reparation of state environment.
Invention content
The present invention provides a kind of river channel ecology bank slopes to protect system, simple in structure, quick construction that can efficiently control river
River and lake anchors alongside the shore slope wave erosion, is lost in reducing water, releases the excess load pressure that the bank slope ecosystem is born, is conducive to bank slope
Or the ecosystem of falling zone develops to nature.
A kind of river channel ecology bank slope protects system, including the anti-filter pad and neonychium being laid on successively on river bank slope, profit
Neonychium and anti-filter pad are fixed on bank slope with anchoring device；
The neonychium is woven by orthogonal warp and weft, and the neonychium includes several regular arrays
Structural unit, each structural unit are pyramid shape, and adjacent structural units are mutually linked by corresponding bottom edge, each structural unit
Pyramid vertex is the support portion mutually to recline with bank slope surface, and the bottom edge of each structural unit is the buffering for being relatively distant from bank slope surface
Portion.
The anti-filter pad is made of polypropylene fibre, allows water to pass through, the particulate matters such as soil is not allowed to pass through, and has length
Phase uses the characteristic of permeable not silting.
The river bank slope includes but not limited to the soil bank slope of rivers and lakes, harder scar, at other with similar
It is also applicable in the application scenarios of feature.

It is as follows：
When anchor cable drawing anchor head is close to loading plate, anchor cable pushes latch segment movement, latch segment compressed spring to be simultaneously retracted into
In guide channel, anchor cable can be automatically by；
When anchor cable negative direction moves (when anchor head and loading plate are located remotely from each other, the moving direction of anchor cable), latch segment follows
Anchor cable moves, and moves closer to anchor cable under the action of guide channel, until anchor cable is pressed on the side wall in anchor cable channel, i.e.,
Latch segment and the side wall in anchor cable channel, which cooperate, clamps anchor cable, prevents the displacement of anchor cable.
Preferably, one end that the guide channel is connected to anchor cable channel is equipped with the limiting section of blocking latch segment.
The limiting section prevents latch segment from being fallen from guide channel with anchor cable channel for stopping latch segment.
Preferably, the latch segment is spherical, one end of the spring is fixedly connected with latch segment, the other end and bearing
It is fixedly connected.
When spherical latch segment is acted on anchor cable, without the concern for action direction, and it is avoided that and anchor cable is caused except abrasion
The damage of outer other modes.The one end of spring far from latch segment is fixedly connected with bearing.
Preferably, the loading plate includes：Polygon frame and the spoke for connecting frame center and vertex, loading plate
Recline neonychium side be equipped with several anti-skidding salient points.
The tensile force of anchor cable is diffused by spoke, increases active force range of the loading plate to the soil body.By anti-skidding
Salient point avoids sliding of the loading plate relative to the soil body.
Each component of anchoring device is all made of corrosion-resistant, durable material, to meet the needs of engineering long-time service.
River channel ecology bank slope provided by the invention protects system, is suitable for the ecology of rivers and lakes ecology bank slope and falling zone
It repairs, the erosion to bank slope and falling zone band such as water surface wave, ship wave, stormy waves, rainfall runoff can be effectively reduced, in vegetation
By protecting axis and root system before restoring, enhances the erosion resistance of river bank slope, reduce the Anti-erosion fatigue of plant, permanently
From the natural ability of erosion, the ecosystem for being conducive to river bank slope or falling zone develops soil protection to nature.
