Abstract
A kind of liftable ground sills, to be horizontally set between the rock mass of two sides and to adopt multistage to arrange, and 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; 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.The utility model has the advantages that: simply, in the dash phase, checkdam draws water and rises the function banked-up water level of performance checkdam for this liftable ground sills reliable in quality, construction; Before there is flood, checkdam water-filling sinks to being hidden in the preformed groove of river bed, does not cause obstruction 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.
Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model is intended to for above-mentioned existing problems, there is provided a kind of liftable ground sills, this liftable ground sills takes water-retaining structure to bear the function of checkdam in conjunction with the mode of empty van buoyancy aid, plays 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.
The technical solution of the utility model:
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 utility model:
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 beneficial effects of the utility model are:
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.

Detailed description of the invention
Embodiment:
A kind of liftable ground sills, as Figure 1-3, be horizontally set between the rock mass of two sides, by concrete preformed groove 5, checkdam 1, buoyancy tank 2, spacing cover plate 6, fill water discharging valve 3 and stack 4 forms, concrete preformed groove is the 5 rectangle transverse grooves excavated in riverbed; Checkdam 1 is cuboid double-layer plate n shape structure, vertical reinforcing rib is provided with between two-layered steel plates, buoyancy tank 2 is prefabricated empty van structure, and checkdam 1 is fixed on the middle part of buoyancy tank 2, and the width of buoyancy tank 2 is identical with the width of concrete preformed groove 5 and be elevated along concrete preformed groove 5 sidewall; Filling water discharging valve 3 is positioned at bottom buoyancy tank 2, and stack 4 is positioned at buoyancy tank 2 top; Two pieces of spacing cover plates 6 are individually fixed on the riverbed of checkdam 1 both sides, concrete preformed groove 5 top, and the width between two pieces of spacing cover plates 6 is identical with the width of checkdam 1, and checkdam 1 is elevated between two pieces of spacing cover plates 6.
In this embodiment, river width 15m, ground sills adopts three sections of settings, and every section of ground sills is of a size of: concrete reserves groove depth 4.5m, wide 4m, long 5m; Dash height of dam 2.5m, long 5m, thick 1.0m; Buoyancy tank height 2m, wide 4m, long 5m; The long 4.0m of spacing cover plate, wide 2m, thick 0.5m; Fill drain pipe diameter 0.2m; Stack caliber 0.1m.
