Description
Technical field
The utility model relates to a kind of cushion pool structure, especially relates to a kind of cushion pool structure for energy dissipating, belongs to Design of The Hydraulic Structure manufacturing technology field.
Background technology
Along with country is to the demand of the clean energy resourcies such as water power, facilitate the construction of Hydraulic and Hydro-Power Engineering, and going deep into further along with water resources and hydropower construction, there is a large amount of dash high dams.In the running of Hydraulic and Hydro-Power Engineering, during in order to reduce dash high dam dam body aperture as table hole, mesopore, deep hole flood discharge, release floodwatering flow, to the scour of dam site and two sides, has built the cushion pool structure for flood-discharge energy-dissipating behind dam accordingly.
Behind traditional high dam dam, cushion pool generally adopts the plunge pool pool bottom structure form of horizonal base plate.The pool bottom structure form of this horizonal base plate has obvious shortcoming: namely when needs carry out emptying inspection to cushion pool, the ponding in cushion pool not easily converges, and both immediately cannot find the position needing to carry out maintenance maintenance, also cannot effectively construct.If employing construction technique under water, not only construction cost is high, and difficulty of construction is large, construction period is long especially.
And when cushion pool larger, traditional " base slab is simply trapezoidal " structure water cushion side of a pond wall is higher, is not easy to construction and the maintenance of cushion pool; When flood discharge power in dam body aperture is larger, traditional " base slab is simply trapezoidal " plunge pool floor is that broken line is crossing with the angle of cut place of abutment wall, under release floodwatering flow that is long-term, flood tide hits effect, easily erosion attack occurs.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of construction and maintenance all very easily for the cushion pool structure of energy dissipating.
For solving the problems of the technologies described above adopted technical scheme be: a kind of cushion pool structure for energy dissipating, comprise the cushion pool body by two road bank interceptions, the inverted trapezoidal structure that the projection of described cushion pool body in its cross section is big up and small down, two hypotenuses of the described cushion pool body of inverted trapezoidal structure are respectively respectively provided to a few packway extended along water (flow) direction.
The beneficial effects of the utility model are: by two hypotenuses of the described cushion pool body of big up and small down inverted trapezoidal structure, are respectively respectively provided to a few packway extended along water (flow) direction.Like this, when will to described cushion pool body be no matter bottom or the skew wall on both sides detect and repair construction time, no matter that some small-sized or simple equipment tool of constructor or construction just can deliver to by described packway the position that described cushion pool needs repairing very easily, both convenient maintenance, convenient construction again.Change in prior art, as long as a bit, that I guess very little inspection or maintenance construction all need the problem employing main equipment.
Further, described each bar packway is one-body molded with corresponding described hypotenuse.
Further, two of the described cushion pool body in inverted trapezoidal structure are connected by rounding off syndeton between hypotenuse with bottom.
The preferred embodiment of such scheme is, described rounding off syndeton is circular arc line transition connecting structure, elliptic curve transition connecting structure or wet strange curve transition syndeton.
Further, the bottom of described cushion pool body is provided with water collecting structure.
The preferred embodiment of such scheme is, described water collecting structure is along the downward-sloping slope being arranged on described two road bank upstream sides of water (flow) direction.
Further, the angle of described slope and horizontal plane is not more than 1.5 °.
Further, described slope is no more than the bottom of described cushion pool body along 1/3rd of water (flow) direction length along the length of water (flow) direction.

Be labeled as in figure: two road banks 1, cushion pool body 2, packway 3, hypotenuse 4, bottom 5, slope 6, rounding off connect 7.
Detailed description of the invention
As shown in Figure 1, Figure 2, be that a kind of construction of providing of the utility model and maintenance are all very easily for the cushion pool structure of energy dissipating shown in Fig. 3 and Fig. 4.Described cushion pool structure comprises the cushion pool body 2 tackled by two road banks 1, the inverted trapezoidal structure that the projection of described cushion pool body 2 in its cross section is big up and small down, two hypotenuses 4 of the described cushion pool body 2 of inverted trapezoidal structure are respectively respectively provided to a few packway 3 extended along water (flow) direction.Above by two hypotenuses 4 of the described cushion pool body 2 of big up and small down inverted trapezoidal structure, be respectively respectively provided to a few packway 3 extended along water (flow) direction.Like this, when will to described cushion pool body 1 be no matter bottom or the skew wall on both sides detect and repair construction time, no matter that some small-sized or simple equipment tool of constructor or construction just can deliver to by described packway 3 position that described cushion pool needs repairing very easily, both convenient maintenance, convenient construction again.Change in prior art, as long as a bit, that I guess very little inspection or maintenance construction all need the problem employing main equipment.
In above-mentioned embodiment, conveniently cushion pool body 2 and packway 3 are in the construction of construction period, and described each bar packway 3 is one-body molded with corresponding described hypotenuse 4.Simultaneously, in conjunction with environment for use and the operating mode of cushion pool body 2, and the statistical analysis to existing cushion pool use situation, in order to extend the maintenance intervals of described cushion pool body, and then reduction use cost, two hypotenuses 4 of the described cushion pool body 2 in inverted trapezoidal structure are improved to rounding off with the link between bottom 5 and are connected 7 structures, and be preferably circular arc line transition connecting structure, elliptic curve transition connecting structure or wet strange curve transition syndeton.
Again in conjunction with in prior art, when detecting described cushion pool body 2, repairing, adopting suction pump thoroughly emptying cannot drain the situation of the ponding on horizonal base plate, in order to change this situation, being provided with water collecting structure in the bottom of described cushion pool body 2.And described water collecting structure is set to along the downward-sloping slope 6 being arranged on described two road bank 1 upstream sides of water (flow) direction, the gradient of preferred slope 6 is be not more than 1.5 ° with the angle of horizontal plane.In like manner, the conveniently construction of cushion pool body first stage of construction, described slope 6 is no more than the bottom of described cushion pool body 2 along 1/3rd of water (flow) direction length along the length of water (flow) direction.
