Description

Ecological slope protection structure of scour prevention
Technical Field
The utility model relates to an anti-scouring ecological slope protection structure.
Background
With the development of engineering construction fields such as highways, water conservancy and the like, the ecological protection of highways, roadbed slopes, river channels and lake slopes is more and more emphasized by people. A large number of exposed slopes in engineering construction have a great number of potential safety hazards, natural disaster hazards, environmental damage and pollution problems, and directly influence the landscape of roads and rivers and lakes and the environmental coordination along the lines.
The conventional highway and river lake revetments adopt a large amount of hard materials such as reinforced concrete, masonry and the like, and although the safety requirements during construction are met, the relatively serious ecological degradation function is caused. The slope protection methods such as grass seed sowing and green net covering have certain ecological functions, but the slope is difficult to keep stable in the construction period due to the problems that the growth period of grass seeds is slow, the survival rate cannot be guaranteed and the like, and the phenomenon of water and soil loss is easy to occur along with factors such as rainfall, seepage and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing an anti-scour ecological slope protection structure.

a slope body having a slope surface inclined with respect to a horizontal plane;
the three-dimensional water and soil protection blanket is laid on the slope;
planting soil, spreading the mixed grass seeds on the upper surface of the three-dimensional water and soil protection blanket;
and the non-woven fabric is covered above the planting soil.
In order to be beneficial to fixing the three-dimensional water and soil protection blanket, grooves are preferably formed in the top and the bottom of the slope body, the edges of the three-dimensional water and soil protection blanket extend into the grooves, and concrete or backfill soil is filled in the grooves.
Further, preferably, the edge of the three-dimensional soil and water protection blanket is fixed at the bottom of the groove through a fixing assembly, the fixing assembly comprises a plurality of anchor bolts distributed at intervals along the length direction of the groove, and the interval distance between every two adjacent anchor bolts is 0.8-1.2 m.
In order to avoid the edge tilting of the three-dimensional water and soil protection blanket caused by water flow scouring, the three-dimensional water and soil protection blanket preferably comprises a plurality of blanket bodies, the blanket bodies are arranged and overlapped and laid along the water flow direction, the edge of the blanket body positioned at the upstream is overlapped above the edge of the blanket body positioned at the downstream, and the overlapping width of the edge of the blanket body is 10-15 cm.
Further, as preferred, the overlap joint part at carpet body border is fixed through a plurality of anchor bolts that set up along overlap joint length direction interval, and the spacing distance between the adjacent anchor bolts is 0.8 ~ 1.2 m.
Further, preferably, the three-dimensional water and soil protection blanket is fixed on the slope surface by anchor bolts, and the distance between every 2m to 3m2On the slope surface is arranged oneRoot anchoring bolts are arranged on the slope surface in a quincunx shape.
Preferably, the anchor is a U-shaped steel nail to facilitate the firm fixation of the three-dimensional water and soil protective blanket.
In order to facilitate the growth of vegetation, preferably, covering soil is paved above the planting soil, and the non-woven fabric covers the covering soil.
Compared with the prior art, the utility model has the advantages that:
1. the greening effect is good. Because the porosity of the three-dimensional water and soil protection blanket is high, an open ecological platform constructed by the three-dimensional perforated structure can create a suitable environment for seed growth, vegetation can be connected into a piece after growth, and the vegetation coverage rate and landscape effect are good.
2. The anti-scouring capability is strong. Before the lawn is formed, the three-dimensional water and soil protection blanket can provide good holding force for soil, help plants to root better, enable vegetation to bear higher scouring and erosion, and effectively prevent soil loss. After the lawn is formed, the three-dimensional water and soil protection blanket is combined with soil and vegetation to form an integral stable three-dimensional structure body, so that the slope can resist the water flow speed of 3-7 m/s. The three-dimensional water and soil protection blanket has the concave-convex shape, so that water flow can form fine vortex, and the water conservancy energy dissipation effect is achieved, thereby providing an overall stable protection environment for a slope body.
