Abstract
The utility model discloses a dam with from energy dissipation function, by the overflow dam body, choose a class mound, overflow surface, overfall dam afterbody defrlector bucket from the energy dissipation and form, choose the fixed setting of the perpendicular overflow surface of class mound on the overflow dam body from the energy dissipation, it sets up one row at least to choose class mound from the energy dissipation. The utility model discloses a dam with from energy dissipation function sets up on overflow surface can be from the mound body of energy dissipation more than one row, when the lower sluicing stream that has powerful kinetic energy meet have from the energy dissipation function choose class mound the time transversely chosen, change the flow direction, two adjacent chooses the rivers that class mound chooses from the energy dissipation and impactes each other, utilize the energy dissipation of rivers self -energy, the efficiency effect of maxmizing, choose the rivers after most energy is subductd to class mound through several from the energy dissipation, upwards provoke by overfall dam afterbody defrlector bucket again, the energy is subductd totally. Can reduce the erodeing of low reaches, reduce absorption basin's excavation volume, shorten absorption basin length, save the construction investment.
Description
Technical field
The utility model relates to dam field, specifically a kind of dam had from dissipating functions.
Background technology
Dam is block rivers current with the water retaining structure of heading up or adjust flux, has regulated flow, flood control, water supply, generating, improves the functions such as shipping.Person's stubborn problem that dam flood discharge is usually Hydraulic Engineering Design, as features as poor geologic condition, what flip trajectory bucket caused seriously washes away, and can make bank slope collapse, even threatens major project safety.Some large reservoir flood-discharge energy-dissipating very difficult task especially, traditional chooses stream, underflow, bailing bucket stream all cannot receive good effect of energy dissipation.Dam flood-discharge energy-dissipating is the problem that water economic system personnel pay much attention to, method disclosed in CN201933472U, utilize the little bank of choosing of flaring gate pier and dam facing to combine flood-discharge energy-dissipating and have certain effect, but effect is very small.Because flaring gate pier and little bank of choosing all are arranged on dam crest, flow rate of water flow is little herein, and huge energy mainly exists with potential forms, and kinetic energy is very little, and the little bank of choosing of flaring gate pier and dam facing is combined flood-discharge energy-dissipating and only can be cut down kinetic energy, so poor effect.
Utility model content
In order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of dam had from dissipating functions, by overflow dam body, choose stream pier from energy dissipating, spillwag chute, overfall dam afterbody flip bucket form, described from energy dissipating choose stream pier vertical-overflow face be fixedly installed on overflow dam body, described from energy dissipating choose stream pier one row is at least set.
Further, describedly choose stream pier from energy dissipating and comprise and choose stream nose head from energy dissipating, choose stream pier from energy dissipating and choose stream cambered surface, choose stream pier bucket lip from energy dissipating, describedly choose stream pier from energy dissipating and choose stream cambered surface, choose stream pier bucket lip from energy dissipating and be symmetricly set on and choose stream nose head both sides from energy dissipating.
Further, described from energy dissipating choose stream pier arrange arrange more time, rear row chooses stream pier from energy dissipating and to choose from energy dissipating with front row and flow pier interlaced arrangement.
Of the present utility model have from the dam of dissipating functions, more than one row is set on spillwag chute can from the pier body of energy dissipating, when the lower sluicing stream with powerful kinetic energy run into have from dissipating functions choose stream pier time laterally chosen, changed the flow direction, two adjacent chooses the current chosen of stream pier from energy dissipating and mutually clashes into, utilize the energy dissipating of current self-energy, reach maximum usefulness effect, choose stream pier through a few row from energy dissipating and cut down the current after most of energy, upwards provoked by overfall dam afterbody flip bucket, energy abatement totally again.Can washing away downstream be reduced, reduce the excavated volume of absorption basin, shorten absorption basin length, cost saving.

Detailed description of the invention
Be described further below in conjunction with accompanying drawing the utility model.
As Figure 1-5, of the present utility modelly to have from the dam of dissipating functions by overflow dam body 1, to choose stream pier 2 from energy dissipating, spillwag chute 3, overfall dam afterbody flip bucket 4 form, describedly choose stream pier 2 from energy dissipating and comprise and choose stream nose head 21 from energy dissipating, choose stream pier from energy dissipating and choose stream cambered surface 22, choose stream pier bucket lip 23 from energy dissipating, choosing stream pier 2 vertical-overflow face 3 from energy dissipating is fixedly installed on overflow dam body 1, arrange depending on overfall dam height and choose stream pier row from energy dissipating, a minimum row, rear row chooses stream pier from energy dissipating and flows pier interlaced arrangement with front-seat to choose from energy dissipating; Choose stream pier from energy dissipating to choose stream cambered surface 22, choose stream pier bucket lip 23 from energy dissipating and be symmetricly set on and choose stream nose head 21 both sides from energy dissipating.
During reservoir spillway, open floodgate, let out under being in high-order water body, the powerful potential energy that water body has gradates as kinetic energy, flow velocity sharply increases, run into have from dissipating functions choose stream pier time laterally chosen, two adjacent chooses the current chosen of stream pier from energy dissipating and mutually clashes into, and utilizes the energy dissipating of current self-energy, reach maximum effect of energy dissipation, choose stream pier through a few row from energy dissipating and cut down the current after most of energy, more upwards provoked by overfall dam afterbody flip bucket, energy abatement totally.Can washing away downstream be reduced, reduce the excavated volume of absorption basin, shorten absorption basin length, cost saving.
