Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering technical field, relates to a kind of energy-dissipating structure, particularly relates to a kind of new structure of absorption basin.
Background technology
For the high-velocity flow energy dissipating that outlet structure escape works are exported, generally in outlet structure escape works outlet, energy-dissipating structure is set, at energy-dissipating structure tail end, tail bank is set, in energy-dissipating structure, forms in advance certain cushion pool, during outlet structure escape works earial drainage, export high-velocity flow by preformed plunge pool.Due between outlet structure escape works outlets and energy-dissipating structure energy dissipating tail bank without any energy-dissipating installation, high-velocity flow is still difficult to reach good effect of energy dissipation under the energy dissipating effect of cushion pool, when current flow velocity after energy dissipating tail bank still larger, downstream river course and building are formed and seriously wash away phenomenon, jeopardize downstream building safety.In addition, if reach desirable effect of energy dissipation, need to increase energy-dissipating structure along water (flow) direction structural configuration, the more close downstream river course of energy dissipating tail bank, causes downstream river course to excavate on a large scale, makes engineering construction claim for eot, increases engineering construction difficulty and investment.Domestic water electrical engineering is taked at outlet structure escape works arranged downstream energy-dissipating structure conventionally as husky a small bay in a river, Suofengying etc. at present, because energy-dissipating structure desired structure size is larger, causes downstream river course dig on a wide area, technical difficulty is large, construction period is long, and construction investment is large, and has larger security risk.Therefore, existing energy-dissipating structure or not ideal enough.
Utility model content
For addressing the above problem, the utility model provides a kind of new structure of absorption basin, can overcome the deficiencies in the prior art, can improve the energy dissipating effect of energy-dissipating structure, the high-velocity flow that guarantees outlet structure escape works outlet can reach the ideal effect of expectation under energy-dissipating structure cushion pool and continuous tooth bank energy dissipating effect, guarantees engineering safety operation.
For realizing the purpose of this utility model, a kind of new structure of absorption basin, comprise outlet structure escape works, downstream at outlet structure escape works is provided with absorption basin, absorption basin is permanent building, wherein the upstream face in absorption basin, for further slowing down the continuous tooth bank of flow rate of water flow, is provided with at least one energy dissipating tail bank at the downstream of continuous tooth bank tail end.Continuous tooth bank arranges at least twice in absorption basin, specifically according to the make out the scale of engineering.The height of continuous tooth bank is no more than 1.5m.The height of energy dissipating tail bank is greater than the height of continuous tooth bank.Building as monolithic concrete block structure of the base plate of continuous tooth bank and energy dissipating tail bank and absorption basin and described outlet structure escape works.
The beneficial effects of the utility model are: adopt in the absorption basin side that meets water continuous tooth bank is set, can improve the energy dissipating effect of energy-dissipating structure, guarantee that high-velocity flow can reach ideal effect under the effect of continuous tooth bank and cushion pool, guaranteed engineering safety operation; Continuous tooth bank height is no more than 1.5m, also can not surpass energy dissipating tail bank height, and absorption basin run duration flow-shape is smooth-going, can not produce cavitation erosion and scour phenomenon; Greatly shortened absorption basin physical dimension, simplify working procedure, saved human and material resources resource, accelerated absorption basin construction speed, the function of permanent building obtains normally bringing into play safe operation simultaneously, and has quick construction, reliable, the economically viable feature of technology.
accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model;
Fig. 2 is floor map of the present utility model.
Being labeled as in accompanying drawing: 1-outlet structure escape works, 2-absorption basin, 3-continuous tooth bank, 4-energy dissipating tail bank.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2, this novel energy-dissipating structure of the present utility model, it is, in outlet structure escape works 1 downstream, absorption basin 2 is set, in absorption basin 2 side that meets water, be provided with continuous tooth bank 3, it also comprises the energy dissipating tail bank 4 that is arranged at absorption basin 2 afterbodys, continuous tooth bank 3 is highly generally no more than 1.5m, also can not surpass energy dissipating tail bank 4 height.Absorption basin 2 is permanent hydraulic structure structure.As shown in Figure 1, continuous tooth bank 3 and energy dissipating tail bank 4 are monolithic concrete block structure with the bottom slab concreting of absorption basin 2 and outlet structure escape works 1.
The utility model, when implementing, arranges continuous tooth bank 3 by the side that meets water at absorption basin 2, has effectively improved the energy dissipating effect of absorption basin 2, guarantees engineering safety operation.Compared to existing technology, the utility model is simple in structure, quick construction, effect of energy dissipation are easy to guarantee, simultaneously owing to taking to arrange continuous tooth bank 3, continuous tooth bank 3 is highly generally no more than 1.5m, and difficulty of construction is not little, technical security is reliable.The utility model not only simple in structure, technology is reliable, and economically feasible, for novel energy-dissipating structure has been established technical foundation.
Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
