Description
Technical field
The present invention relates to a kind of method and devices for reducing Simulations of Water Waves Due To Landslides and endangering dam, belong to hydraulic and hydroelectric engineering protection knot
Structure technical field.
Background technology
Because power station is typically all to build mountain area in, a certain number of accumulation bodies are distributed with around reservoir area.In heavy rain season, portion
Divide accumulation body that may come down because of stability problem.When there is landslide, the water in storehouse can be caused to be formed and surged,
The high energy current for surging formed can cause high risks to dam.Landslide in order to prevent, currently used method master
Have following several：One kind is that unstable massif administer to stabilize it；Another kind is when building dam, increases dam
Thickness and height；Also one kind is to reduce operating water level.The method of the prior art in general all can be by a relatively large margin increase
Construction investment reduces on-road efficiency, and it is undesirable in turn result in scheme economic indicator.
The content of the invention
It is an object of the present invention to provide a kind of method and devices for reducing Simulations of Water Waves Due To Landslides and endangering dam, can effectively cut
The weak harm surged to dam formed by landslide, to ensure the operational safety of dam and power station, so as to overcome existing skill
The deficiency of art.
The technical proposal of the invention is realized in this way：
A kind of method that endanger dam of reduction Simulations of Water Waves Due To Landslides of the present invention, this method be Simulations of Water Waves Due To Landslides possibility spot 1~
The one or multi-channel barrier bubbled through the water column is set on the water surface at 2km, and weakening landslide by the barrier bubbled through the water column forms
Streaming potential of surging；The flow velocity of Simulations of Water Waves Due To Landslides and height are reduced to downstream dam can be in tolerance range, to ensure that landslide is gushed
Wave will not damage to dam.
In preceding method, the barrier bubbled through the water column hangs grid using folding rule shape, and folding rule shape hangs grid both ends and bank
Anchor upsetting connects；Folding rule shape, which hangs grid, to be made of one group of hinged folding rule unit of head and the tail；It is set between two sides at interval of certain distance
There are one buoyancy tank, buoyancy tank is connected with folding rule unit nearby；Folding rule unit close to bank is hinged with anchor upsetting on the bank.
For the device that a kind of reduction Simulations of Water Waves Due To Landslides of the present invention of the above method endangers dam, including being located at two sides
Anchor upsetting；Between the anchor upsetting of two sides grid are hanged equipped with folding rule shape；Folding rule shape hangs anchor upsetting of the grid both ends respectively with two sides and is hinged；Folding rule shape
Outstanding grid are made of the folding rule unit that one group of head and the tail is hinged or is flexible coupling；One group be equally spaced is equipped between two anchor upsettings to float
Case, each buoyancy tank are hinged with folding rule unit nearby.
In aforementioned device, the folding rule unit includes four square steel, and every square steel both ends are equipped with hinge hole, four sides
Steel both ends are mutually hinged the quadrangle component for forming retractable through axis pin；The quadrangle component of retractable is left
End is hinged through vertical single binaural connector and the folding rule unit of left neighbour, and the quadrangle member right end of retractable is through vertical ears
Connector and the folding rule unit of right neighbour are hinged.
In aforementioned device, the quadrangle member lower of the retractable through parallel binaural connector and buoyancy tank at the top of
Monaural connector is hinged.
By adopting the above-described technical solution, compared with prior art, the present invention the device of the invention works as Simulations of Water Waves Due To Landslides mistake
When coming, surge from grid body by being blended by water turbulence and realizing energy dissipating, reduced Simulations of Water Waves Due To Landslides speed and height, pass through multistage
After outstanding grid, Simulations of Water Waves Due To Landslides speed and height can be reduced to acceptable degree.So reach the Simulations of Water Waves Due To Landslides before dam
Through not damaging substantially to dam.It is not completely by water impact, even if preceding several outstanding grid meetings due to having gap among outstanding grid
It is destroyed, outstanding grid below can also play a role.In addition, Simulations of Water Waves Due To Landslides is rare events, then in time to hanging grid after occurring
It is repaired, possible Simulations of Water Waves Due To Landslides next time can be met.Compared to past Simulations of Water Waves Due To Landslides control method, smaller, effect is invested
Preferably, there can be greatly economic imitate to avoid the generation of large-scale slope treatment and increasing dam height or control operating level
Benefit.
