Description

Ecological bank protection of hydraulic engineering

Technical Field

The invention relates to the technical field of river channel revetments, in particular to a hydraulic engineering ecological revetments.

Background of the invention

Ecological slope protection, which is a slope protection technology for supporting a slope or a side slope by basic knowledge of subjects such as comprehensive engineering mechanics, soil science, ecology, phytology and the like to form a comprehensive slope protection system consisting of plants or engineering and plants; after the excavation side slope forms, through planting the plant, utilize the plant and rock, the interact of the soil body (root system anchor effect) protects, consolidates the side slope top layer, makes it can satisfy the stable requirement on side slope top layer, can resume the slope protection mode of destroyed natural ecological environment again, is an effectual bank protection, solid slope means, and the bank protection of river course all adopts ecological bank protection.

The existing Chinese patent with reference to publication number CN107217642B discloses an ecological slope protection, which comprises slope surfaces obliquely laid on two sides of a river channel, a pull rope capable of sinking into the river under a normal state is arranged between the two slope surfaces, and a stretching device capable of stretching the pull rope from the river to the river surface is arranged on the slope protection. Under the normal condition, the stay cord is sunken in the river bottom, the stay cord is hidden in the river course, can not cause the influence to the navigation of the ship in the river course or people's normal activity, when someone falls into water and needs the succour when discovering, stretching device pulls out the stay cord from the river course, make the stay cord emerge the river course, like this when the succour when the circumstances that physical power is not sufficient appears, can be with the help of the stay cord, as supporting, make it can temporarily cushion or follow the stay cord and swim back the river course both sides, avoid it at the succour in-process, because physical power consumption is too big and lead to oneself unable bank limit of swimming back, the success rate of rescue has been improved.

The above prior art solutions have the following drawbacks: in actual life, the steadiness of above-mentioned bank protection is relatively poor, takes place the phenomenon that soil erosion and water loss leads to the landslide easily, bank protection self can't be stable, what talk about rescue people, and then greatly reduced the safeguard effect of bank protection.

Disclosure of Invention
