Description
Technical field
The utility model relates to the absorption basin that a kind of dam uses, especially a kind of Novel T-shaped pier energy dissipator being provided with T-shaped pier.
Background technology
Along with China's construction of hydropower facilities popularization, the large storehouse of high dam is constantly built, high head and large flow outlet structure escape works flood-discharge energy-dissipating problem is more and more outstanding, the major way of current this difficult problem of solution in downstream absorption basin, dissipates most of flood discharge concentration of energy flood energy in underflow type energy dissipation by hydraulic jump mode.Therefore, a kind of effect of energy dissipation is good, and solid durable, construction cost is low, and energy dissipating is suggested apart from short absorption basin.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel T-shaped pier energy dissipator.
The utility model comprises absorption basin (1), it is characterized in that: in absorption basin (1), be provided with T-shaped pier (3) and tail bank (4), T-shaped pier (3) is made up of front pier (3-1) and supporting leg (3-2), one end of supporting leg (3-2) is connected in T font with Qian Dun (3-1), the other end is connected with tail bank (4), and the height of tail bank (4) is higher than the height of T-shaped pier (3), at least one of described front pier (3-1) and tail bank (4) is provided with anti-ly chooses cover plate (2), prevent that choosing cover plate (2) stretches out front pier (3-1) and tail bank (4).
During actual use: when high-velocity flow flows in absorption basin (1), horizontal impact is to T-shaped pier (3) front pier (3-1) place, current reverse vertically upward, due to anti-stop of choosing cover plate (2), after current carry out violent rotary roll and turbulent fluctuation in subrange, tail bank (4) is flow to along T-shaped pier (3) supporting leg (3-2), at tail bank (4) and under preventing choosing the guiding of cover plate (2), current generation secondary rotary roll, ensures that current steadily flow into waste canal (5) by tail bank (4).
As improvement, the described anti-soffit choosing cover plate (3) extension is in being inclined upwardly, and angle of inclination is 15 ~ 45 °, and its thickness is 1/4 of front pier (3-1) thickness.
Above-mentioned angle of inclination preferably selects 30 °.
The above-mentioned anti-soffit choosing cover plate (3) extension is curved.
Compared with prior art, it is good that the utility model has effect of energy dissipation, and solid durable, construction cost is low, and energy dissipating is apart from the feature such as short.

Detailed description of the invention
Embodiment 1: with reference to Fig. 1 ~ 2, for the structural representation of the utility model embodiment 1, comprise absorption basin 1, it is characterized in that: be provided with T-shaped pier 3 and tail bank 4 in absorption basin 1, T-shaped pier 3 is made up of front pier 3-1 and supporting leg 3-2, and one end and the front pier 3-1 of supporting leg 3-2 are that T font is connected, the other end is connected with tail bank 4, and the height of tail bank 4 is higher than the height of T-shaped pier, at least one of described front pier 3-1 and tail bank 4 is provided with anti-ly chooses cover plate 2, anti-ly chooses cover plate 2 and stretches out front pier 3-1 and tail bank 4.
During actual use: when high-velocity flow flows in absorption basin 1, Dun3-1Chu before horizontal impact to T-shaped pier, current reverse vertically upward, due to anti-stop of choosing cover plate 2, after current carry out violent rotary roll and turbulent fluctuation in subrange, flow to tail bank 4 along T-shaped pier supporting leg 3-2, at tail bank 4 and under preventing choosing the guiding of cover plate 2, current generation secondary rotary roll, ensures that current steadily flow into waste canal 5 by tail bank 4.
Embodiment 2: compared with embodiment 1, the difference of the present embodiment is: the described anti-soffit choosing cover plate 3 extension is in being inclined upwardly, and angle of inclination is 30 °, and its thickness is 1/4 of front pier 3-1 thickness.
Embodiment 3: compared with embodiment 2, the difference of the present embodiment is: angle of inclination is 15 °.
Embodiment 4: compared with embodiment 2, the difference of the present embodiment is: angle of inclination is 45 °.
