Description

Suspension type greening slope protection for pumped storage power station

Technical Field

The invention relates to the technical field of greening slope protection, in particular to a suspension type greening slope protection for a pumped storage power station.

Background

The slope near the water inlet and outlet of the pumped storage power station in northern areas of China is subjected to multiple damages such as water level dip generated by daily pumping power generation, frost heaving in winter and the like due to the impact and scrubbing of waves, and the slope near the water inlet and outlet is easy to collapse, peel and destroy.

For the traditional water inlet and outlet side slope, if the new construction is within the cofferdam protection range, the construction is more convenient because of dry construction conditions; if the construction condition is beyond the blocking range of the cofferdam or the damaged side slope of the established engineering is repaired, the construction condition of the construction method is not dry. For this purpose, methods are generally used in which underwater stone is thrown, water masonry slurry is used as a support form for the side slope, and dry masonry or poured concrete is used. Such slope forms are frequently subjected to wave impact washing, water level suddenly dropping and frost heaving in winter, and often cause reverse filtration failure due to reverse filtration quality defects or no reverse filtration material, so that soil bodies positioned at the lower part are washed, void is caused, slope protection materials lose supporting bodies to cause slope collapse, and the whole or partial revetment is destroyed; or because the thickness of the rigid slope protection and the cushion layer (or reverse filtration) is smaller than the local maximum frozen soil depth, the blocked soil body is frozen and swelled, so that the slope protection body is cracked and destroyed by expansion and then is washed by waves, and the slope protection is collapsed and peeled off and destroyed. The damage is often repaired, and the constructed engineering is limited by daily operation conditions, no construction road and other conditions, so that the repair is difficult and a large amount of manpower and material resources are consumed.

In addition, the pumped storage power station is mostly in the form of slope protection such as scenic spots, concrete or slurry masonry, the problems are easy to occur, and meanwhile, rigid 'reinforced concrete forest' type artificial marks and gray negative landscapes are easy to form and are easy to be uncoordinated with surrounding environment and landscapes.
