Abstract
Disclosed is a lifting submerged dam. The lifting submerged dam is transversely arranged between rocks of two shores and is arranged in a multiple segment manner and comprises a concrete preformed groove, a water baffling dam body, a buoyancy tank, two limit cover plates, a water feed and drainage valve and an exhaust pipe. The concrete preformed groove is a cuboid transverse groove digged in the riverbed; the water baffling dam body is in a cuboid double-layered steel plate n-shaped structure, the buoyancy tank is in a prefabricated tank structure, and the water baffling dam body is fixed to the middle of the buoyancy tank; the water feed and drainage valve is located at the bottom of the buoyancy tank, the exhaust pipe is located at the top of the buoyancy tank, and the two limit cover plates are fixed to the riverbed of two sides of the water baffling dam body at the top of the concrete preformed groove. The lifting submerged dam is reliable in quality and easy to construct; in the water baffling period, the water baffling dam body is lifted to baffle water and bank up the water level; before the flood, the water baffling dam body is sunk and hidden into the preformed groove of the riverbed, and flood release is free of blockage; the problems of river water level and amount adjustment and control in the dry season can be solved through low cost, and the river ecological landscaping effect can be improved.
Description
Technical field
The present invention relates to the checkdam in hydraulic engineering, particularly a kind of liftable ground sills.
Background technology
In recent years, the river comprehensive realignment demand for the purpose of water environment and Ecology protection and view and entertainment environment are built increases day by day.Property river, China mountain area Flood flow is large, the depth of water and the water surface is wide, and at non-flood period, then flow is less, and water is shallow and the water surface is narrow, and River Landscape sight is affected.In order to not hinder flood passage, rubber dam is usually adopted to carry out harmony height non-flood period water level, but many bed loads during mountain stream flood passage, and relatively large sandstone easily damage rubber dam bag, and therefore rubber dam should not be used for mountain stream non-flood period and chokes water.In this context, for addressing this problem, possess for the research and development of river feature the emphasis that the ecological hydraulic structure of multi-functional low impact is current development.
Summary of the invention
Object of the present invention is intended to for above-mentioned existing problems, provides a kind of liftable ground sills, and this liftable ground sills takes water-retaining structure to bear the function of checkdam in conjunction with the mode of empty van buoyancy aid, and play the function of checkdam in non-flood season, banked-up water level, saves the water yield; Sink in the preformed groove of potential river bed in flood period, do not hinder flood passage, ensure flood passage safety; This liftable ground sills structure is simple, and easy construction, has significant economical and technical benefit.
Technical scheme of the present invention:
A kind of liftable ground sills, to be horizontally set between the rock mass of two sides and to adopt single hop or multistage to arrange, by concrete preformed groove, checkdam, buoyancy tank, spacing cover plate, fill water discharging valve and stack forms, concrete preformed groove is the rectangle transverse groove excavated in riverbed; Checkdam is cuboid double-layer plate n shape structure, and buoyancy tank is prefabricated empty van structure, and checkdam is fixed on the middle part of buoyancy tank, and the width of buoyancy tank is identical with the width of concrete preformed groove and be elevated along concrete preformed groove sidewall; Filling water discharging valve is positioned at bottom buoyancy tank, and stack is positioned at buoyancy tank top; Two pieces of spacing cover plates are individually fixed on the riverbed of checkdam both sides, concrete preformed groove top, and the width between two pieces of spacing cover plates is identical with the width of checkdam, and checkdam is elevated between two pieces of spacing cover plates.
Operating principle of the present invention:
In non-flood season, the discharge of river is less, water level is lower, and checkdam enters the dash phase, by outside pumping for water pump, makes to be full of air in buoyancy tank, and under buoyancy, water-retaining structure and buoyancy tank combination rise, and the checkdam of rise will play the function of checkdam.
As larger rainfall, before flood is formed, utilize outside water pump to water filling in buoyancy tank, along with the increase of the water yield in buoyancy tank, water-retaining structure and buoyancy tank combination sink gradually.After buoyancy tank is full of water, water-retaining structure, by being hidden in completely in concrete preformed groove, returns to original state, does not cause obstruction to flood passage.
The invention has the beneficial effects as follows:
This liftable ground sills has standardized production, reliable in quality, the simple feature of construction, and in the dash phase, checkdam draws water and rises the function banked-up water level of performance checkdam, saves water body; Before there is flood, checkdam water-filling sinks to being hidden in the preformed groove of river bed, does not cause obstruction, ensured flood passage safety to flood passage; Solve again a regulation and control difficult problem for river water level in dry season, the water yield simultaneously with lower cost, be conducive to promoting river channel ecology landscaping effect.
