Description
Technical field
The present invention relates to the water retaining structure in hydraulic engineering, particularly the box checkdam of a kind of hydraulic liftable.
Background technology
At present, what the checkdam in hydraulic engineering adopted usually is gravity dam, arch dam, earth and rockfill dam, buttress dam etc.The effect that dash sluices in large-scale engineering of above large-scale checkdam is given prominence to, but in the location that mountain area small rivers etc. is special, large-scale checkdam applicability is poor, and capital consumption is large, long in time limit, earning cycle is long, is difficult to carry out for general minor works.Be directed to above Problems existing, design the box water-retaining structure of a kind of hydraulic liftable, the plurality of advantages had not available for the former is used in small-sized river course, use minimum resource to solve the problem of space and Annual distribution inequality in mountain area, solve irrigation in mountain area, living water use, avoid flood to problems such as the danger that people residence is caused.The novel checkdam of the design can freely be elevated, waterproof in flood season dash in dry season and can be submerged under riverbed and do not affect flood passage, sand discharge; Outside is concrete structure, and can prevent the corrosion function of silt, bending resistance is strong; Compare with common gate, eliminate a lot of accessory structure, saved resource.
Summary of the invention
The object of the invention is to for above-mentioned existing problems, provide a kind of hydraulic liftable box checkdam, this dam structure is simple, save fund, the duration is short, easy to implement, operation maintenance convenient, has significant technique effect and very strong practicality.
Technical scheme of the present invention:
The box checkdam of a kind of hydraulic liftable, be horizontally set between the rock mass of two sides, comprise foundation, checkdam part and hydraulic hoist part, foundation comprises the rectangular channel of concreting and the armed lever service depot of hydraulic hoist, it is measure-alike that the size of rectangular channel and three rectangle dam bodys combine, the armed lever service depot of six hydraulic hoists is positioned at the bottom of rectangular channel, and two medial surfaces of rectangular channel near bank are respectively equipped with slideway, and slideway top is provided with watertight rubber; Checkdam part is connected to form by keyway mode by the M shape checkdam that three sizes are identical, the total length of three checkdams is identical with the length of rectangle dam body rectangular channel, each checkdam inside is equipped with reinforcing rib, whole checkdam is elevated along slideway in the rectangular channel of rectangle dam body, when whole checkdam reduces as far as possible, whole checkdam upper surface and riverbed maintain an equal level, and when whole checkdam rises to peak, checkdam and bank rock mass form the overflow dam allowing overcurrent; Hydraulic hoist part comprises hydraulic hoist and six hydraulic hoist armed levers, hydraulic hoist is arranged in ground control room, the lower end of six hydraulic hoist armed levers is positioned at the armed lever service depot of rectangular channel bottom, and the upper end of six hydraulic hoist armed levers connects with the top cover soffit of three checkdams respectively.
Operating principle of the present invention and beneficial effect:
1) the Lifting/lowering box type checkdam designed controls upper and lower motion by hydraulic pressure armed lever and carries out dash.Under casing dam being submerged in riverbed completely when flood season needs flood discharge by the effect of armed lever, do not affect the flood passage in river, sand discharge; When dry season, when needing harmony high water level to store the water yield, armed lever rises casing dam structure release riverbed, adjusts to the height required for river course, stops advancing of streamflow, reach the target of regulation and control upper pond level.
2) outside of box checkdam is solid concrete structure, when the riverbed of mountain area bed load, effectively prevent from being entrained in silt in river and, for the corrosion function of common iron structure, compared to common gate, rubber dam, the requirement of river, geology is seemed to have compliance.Placing the rib of steel in checkdam inside, improving the flexural deformation because water pressure causes when rising.
3) this hydraulic liftable checkdam is compared with the gate structure of dash in the past, can not need to arrange the accessory structures such as gate floor, gate pier, only on riverbed, need carry out excavating the process such as grouting, save a large amount of financial resources, material resources, manpower.This design by greatly flexible engineering for the feasibility of small rivers, dredging waterway scheme and innovative research.
Advantage of the present invention is:
The enforcement of this checkdam only simply need dig out grouting treatment to riverbed, river course, lifting is controlled by the effect of hydraulic hoist, structure is simple, save fund, the duration is short, easy to implement, operation maintenance convenient, has significant technique effect and very strong practicality.
