Detailed description of the invention
Fig. 1 is front view of the invention;
Fig. 2 is top view of the invention.
Specific embodiment
The present invention provides a kind of efficient bevel-type waterpower stilling pool slab and its construction methods, especially suitable for high water head pipeline water Energy dissipating is flowed, cone structure is innovatively used, makes water flow along cone diffusion, rolling, friction, has that energy dissipating is high-efficient, energy dissipating is empty Between less, it is simple and reliable for structure the features such as.The present invention is described in detail with specific embodiment with reference to the accompanying drawings of the specification.
As depicted in figs. 1 and 2, a kind of efficient bevel-type waterpower stilling pool slab provided by the invention, including stilling pool slab body 10, pressure Pipeline 20, anchor block 30 and the power cone 40 that disappears.
Stilling pool slab body 10 is reinforced concrete structure, is in cylinder type, is embedded in below ground, well top is above ground level, and Jing Ding Equipped with overflow crest of weir 11, the outside of overflow crest of weir 11 is equipped with outlet canal 12.To ensure the stilling pool slab in high water head, high flow rate operation Body 10 is stablized, and 10 main structure of stilling pool slab body is preferably embedded in below ground.
20 level of pressure pipeline penetrates the inner wall for the vertical that disappears, and 90 ° of turning parts 21 are arranged, the outlet of turning part 21 vertically to Under.Anchor block 30 is fixed by the inner wall of reinforcing bar and the vertical that disappears, and is poured to be formed using armored concrete, and turning part 21 passes through anchor block 30.The center of stilling pool slab body 10 is arranged in the power that disappears cone 40, and the outlet of turning part 21 is faced at the top of the power that disappears cone.
Water flow enters the vertical that disappears by pressure pipeline 20, and by turning part 21, water flow is vertically impacted to the power cone 40 that disappears, water Stream is spread downwards along the surrounding for the power cone 40 that disappears, then is turned back upwards from shaft bottom, and it is opposite that inside and outside flow direction is formed in stilling pool slab body 10 Two bursts of water flows that liquidate, further diffuse into one another to form a large amount of irregular small whirlpool bodies, reach energy dissipating purpose, the water flow after energy dissipating By draining into downstream outlet canal 12 outside overflow crest of weir 11.
Preferably, the power that disappears cone 40 uses steel casing, and the power that disappears including being welded and fixed bores the lower section of vertical cone that saves and disappear, and disappears The inside of power cone 40 has poured concrete.Concrete inside the power that disappears cone 40 can greatly enhance the power cone 40 that disappears intensity and Stability, the structure for being divided into upper and lower two section facilitate pouring for construction and concrete.
Preferably, well top height above ground level is 1.5~2.5m, it is ensured that stilling pool slab body 10 is under the impact of high-velocity flow Overall operation is stablized, and avoids vibrating.
Preferably, the turning part 21 that the distance between outlet at top and turning part 21 of the power that disappears cone 40 is 2~3 times Caliber.This distance makes the water flow come out from turning part 21 have certain flow rate, and impacts again after obtaining certain speed The top of the power that disappears cone 40, thus by water stream and uniform diffusion downwards.
Preferably, the turning between the bottom plate and inner wall of stilling pool slab body 10 is connected using cambered surface, and cambered surface connects so that water flow It can be impacted upwards after reaching shaft bottom, and then form collision and rolling with downward water flow, achieve the purpose that efficient energy dissipating.
The present invention also provides the construction methods of the efficient bevel-type waterpower stilling pool slab of above structure, comprising the following steps:
S1, foundation excavation excavate well with excavator, reinforce well draining, keep well wall to stablize, basis is arranged in sand On cobble or basement rock, after base surface leveling, 10cm thickness C15 concrete is laid with as 10 blinding layer of stilling pool slab body;
S2,10 reinforcing bar concrete placings of stilling pool slab body, the bottom plate and borehole wall reinforcing bar of binding stilling pool slab body 10, casting concrete, and Vibration compacting, concrete must be very strictly controlled the ratio of mud;
S3, the power that disappears cone 40 are constructed, and the power that will disappear cone is lifted to stilling pool slab body 10, in the bottom plate center of stilling pool slab body 10 Installation is in place;The size for the power cone 40 that disappears can be designed according to actual needs;
S4, pressure pipeline 20 and anchor block 30 are constructed, and after pressure pipeline 20 is installed in place, bind anchor block 30 and straining beam reinforcing bar, 30 concrete of anchor block is poured, is connected and fixed stilling pool slab body 10 and anchor block 30 integral;
S5, outlet canal 12 are constructed, and the bottom plate and side wall armored concrete of outlet canal 12, outlet canal 12 and stilling pool slab body are poured Subsiding crack is set at 10 overflow weir, sets rubber fastening band in subsiding crack.
Wherein in step S3, the power that disappears cone 40 divides on the power cone that disappears the lower section of power cone that saves and disappear, and the lower section lifting of the power that will first disappear cone is extremely 10 bottom plate of stilling pool slab body, and top aperture casting concrete in place, to save under being bored by the power that disappears is installed, then lifting disappears on power cone It saves and is welded to connect and fixes with lower section.
Waterpower stilling pool slab body 10 provided by the invention has the advantage that
1) structure is simple: primary structure is made of anchor block 30, stilling pool slab body 10,40 three parts of the power that disappears cone, with stilling pool slab It is centered on body 10 that triplicity is integral, it is compact-sized simple;
2) efficient energy dissipating: due to the diffusion that liquidates by the power cone that disappears, make to form two of flow direction on the contrary in stilling pool slab body 10 Stock solid current, sufficiently liquidate friction in entire well, reaches efficient energy dissipating purpose, and practical example shows that effect of energy dissipation extremely has Effect, the water after energy dissipating flow out water steadying;
3) space occupied is small: since anchor block 30 and the power cone 40 that disappears are arranged in stilling pool slab body 10, it not being arranged again Its energy dissipater's building arranges very compact, space occupied very little;
4) project cost is low: it is ingenious using a simple cone structure come energy dissipating, do not arrange conventional energy dissipating baffle, The conventional structures such as force-eliminating chamber, stilling pond reduce energy dissipater's building engineering amount, construction investment are reduced, according to the same of built engineering Condition design compares, and reduces architectural engineering investment about 25~35%, has good economic benefit.
The invention is not limited to above-mentioned preferred forms, and anyone should learn that is made under the inspiration of the present invention Structure change, the technical schemes that are same or similar to the present invention are fallen within the scope of protection of the present invention.
