A dam slope protection device

Abstract

The invention relates to the technical field of embankment slope protection, and discloses an embankment slope protection device, which includes a plurality of embankment protection units installed on the embankment. The embankment protection unit includes a water feeding mechanism, a water diversion mechanism and a protective grille. The blade drive assembly, the blade drive assembly includes a blade hub, a blade device uniformly arranged on the blade hub in the circumferential direction, and a rotating shaft coaxially arranged with the blade hub, the blade device includes blades and elastic members, and the blades are mounted on the blade hub through the elastic members, The upstream surface of the blade is facing the direction of water flow, one end of the rotating shaft is fixedly connected to the hub of the blade, and the other end is connected to the power input end of the pump body; the slope protection device of the embankment provided by the present invention can transport the water flow in the river channel to the embankment through the pipeline Above, the water delivery process does not consume electric energy, which is energy-saving and environmentally friendly, and ensures the growth of slope protection grass, so as to achieve better slope protection effect, reduce the maintenance cost of slope protection, and is easy to promote and use.

Description

technical field [0001] The invention relates to the technical field of dam slope protection, in particular to a dam slope protection device. Background technique [0002] When choosing grass species on dams, we should choose plants with well-developed root system and strong soil-fixing ability, so as to prevent the river from scouring the dam for a long time and accelerate the water and soil loss of the dam. Bahia Grass is one of the common greening grass species planted on embankments. The successfully planted Bahia Grass lawn is very strong in drought resistance, but there is a problem that this kind of grass is not resistant to waterlogging. Therefore, in the event of river swollen In some cases, the water flow will submerge the grass on the embankment, and the non-waterlogging-tolerant grass is difficult to survive. In addition, the rise of the water level will affect the stability of the soil layer of the embankment, resulting in soil erosion and protection failure. The...

Bahia Grass is one of the common greening grass species planted on embankments. The successfully planted Bahia Grass lawn is very strong in drought resistance, but there is a problem that this kind of grass is not resistant to waterlogging. Therefore, in the event of river swollen In some cases, the water flow will submerge the grass on the embankment, and the non-waterlogging-tolerant grass is difficult to survive. In addition, the rise of the water level will affect the stability of the soil layer of the embankment, resulting in soil erosion and protection failure. Therefore, we choose to plant waterlogging-resistant grass on the embankment. Plants can avoid water and soil erosion caused by long-term submersion of plants by water, but this kind of waterlogging-tolerant plants will also have the problem of not being drought-tolerant, and long-term water shortage will also affect the survival of this type of slope protection plants

Under the current circumstances, in order to ensure the growth of waterlogging-resistant plants on the embankment, it is necessary to ensure timely water supply for this type of plant. The traditional water supply method requires manual watering on time and pumping irrigation, which will undoubtedly consume manpower and material resources. It will also increase the maintenance cost of slope protection
