Description
Technical field
The invention belongs to water conservancy environmental technology field, and in particular to it is a kind of it is simple in construction, easy to use being capable of floating row row
The dam of husky anti-alluvial.
Background technology
The reservoir dam built on present rivers, including gravity dam, Gong Ba, the thorough dam of stone, earth and rockfill dam etc., all it is that front is blocked
Water and the straight dam for forming reservoir capacity, this dam are exactly that control water is carried out " stifled " by way of, violate river waterflow nature
The rule of flowing, although make use of Water Energy, substantial amounts of silt, cobble, drift but the recoil backflow phenomenon produced has but deposited
Float, they make the capacity of reservoir reduce year by year, and floating object must spend substantial contribution and labour to go cleaning.So conventional is this
Dam body researches and develops a kind of dam for being capable of the anti-alluvial of floating row sand discharge with very big using that can cause many insoluble problems
Practical significance.
The content of the invention
It is an object of the invention to provide a kind of dam simple in construction, working stability for being capable of the anti-alluvial of floating row sand discharge.
The object of the present invention is achieved like this, including dam body, and power plant building, the dam body bag are set on the outside of the dam body
Side dam and overfall dam are included, the overfall dam both sides set side dam, the side dam and overfall dam forming V-shape, and the power plant building is set
On the outside of side dam, the overfall dam bottom setting flood and sand discharging hole, the inner side and outer side of the flood and sand discharging hole UNICOM overfall dam,
The flood and sand discharging hole sets gate system to control its break-make.
Two side dams of the present invention and overfall dam forming V-shape, the bottom of overfall dam set flood and sand discharging hole, utilize side dam medial surface
Recoil effect to aqueous fluid, i.e., be obstructed on the left of water body, must move right, and forms right side and flows back, right side is obstructed then must be to the left
Motion, forms left side and flows back, and floating object, silt, cobble etc. is bunched with the middle part of reservoir, utilizing reservoir area gradient flood and sand discharging, profit
With storage capacity absolute altitude overflow blowdown, open flood and sand discharging hole just can arrange the suspended material of reservoir area with passage material from flood and sand discharging hole
Walk, floating object is then drained naturally from spout hole.The dam body flood discharge phase of the present invention can be opened and closed real by intermittent flood and sand discharging hole
Silt cleaning in existing dam body, it is ensured that the capacity and water quality of reservoir area, realizes the purpose of the dynamic current floating row sand discharge in reservoir area.
