Embodiment
It is that one kind provided by the invention is simple in structure as shown in Figure 1 and Figure 2, surface spillways itself building can be made full use of
The checkdam for being provided with surface spillways of energy dissipating.The checkdam includes checkdam body 1, in the checkdam body 1
On be provided with along water (flow) direction extend surface spillways 2, lock chamber system 3 is provided with the surface spillways 2, described lets out
Big vast table hole 2 is opened and closed by the retaining box 4 of the lock chamber system 3, and table hole reality is additionally provided with the surface spillways 2
With weir 5, in the table hole, the downstream of practical weir 5 is provided with energy dissipating and falls bank 6, and the retaining box 4 is arranged in the institute of upstream side
State on table hole practical weir 5, the current let out along under table hole practical weir 5 fall 6 banks by the energy dissipating and fall in downstream
Energy dissipating in the lock chamber system 3.The application in the surface spillways 2 by being additionally provided with table hole practical weir 5, and described
The downstream of table hole practical weir 5 is provided with energy dissipating and falls bank 6, then the retaining box 4 is arranged in the table hole of upstream side
On practical weir 5, and the current for alloing to let out along under table hole practical weir 5 fall bank 6 by the energy dissipating and fall in downstream
The lock chamber system 3 in energy dissipating.In this way, due to the increase setting table hole practical weir 5 only in existing surface spillways 2 and disappear
Bank 6 can be fallen, bank 6 sufficiently can be fallen by energy dissipating using itself building of surface spillways 2 and realize energy dissipating, not only eliminated existing
There is the stiling basin that must be built, but also need not both be reduced again in the larger apron erosion control of stiling basin downstream connection length
Excavation that engineering is built, the quantities such as build, but also can largely reduce up-front investment.At the same time it can also make checkdam
Therefore structure becomes simpler, also easily facilitate construction.
In the above embodiment, in order to solve the problems, such as the cavitation erosion produced under high-velocity flow, reduce cavitation erosion as far as possible and made to building thing
Into infringement, the middle and lower part for falling bank 6 in the energy dissipating is additionally provided with tonifying Qi face 7, and further includes edge with reference to the lock chamber system 3
The design feature of the downstream gate pier 8 of water (flow) direction extension, falls the downstream gate pier beyond bank 6 along water (flow) direction in energy dissipating
Set again on 8 and mend stoma tube 9, the inlet end for mending stoma tube 9 is arranged on the top surface of the downstream gate pier 8, the benefit
The outlet side of stoma tube 9 is arranged on the side of the downstream gate pier 8 highly adaptable with the tonifying Qi face 7;At this time, it is described
The preferred structure in tonifying Qi face 7 is to be arranged on the inner concave that 6 middle and lower part of bank is fallen in the energy dissipating.
Further, in order to eliminate the energy of the lower stream that sluices to greatest extent, and water conservancy project is protected to build thing, the table hole is practical
The weir face on weir 5 is in semi-parabolic structure;And also set on the lock chamber system terrestrial between downstream gate pier 8 described in two adjacent groups
Lock floor 10 is equipped with, the current let out along under table hole practical weir 5 fall bank 6 by the energy dissipating and fall in the lock chamber
Energy dissipating on bottom plate 10.At this time, the retaining box 4 generally includes maintenance lock 11 and work lock 12, the maintenance lock 11 and institute
The work lock 12 stated is arranged along water (flow) direction order.The work lock 12 can be divided into arc work lock or plate work again
Lock.
In conclusion the beneficial effects of the invention are as follows:By the above-mentioned Energy Dissipation Modes of the present invention, current are most of after lockage
Energy is during down stream and down stream back brake chamber interior disappears.The hydraulic jump re-formed after down stream voluntarily disappears in river downstream, energy
Sluice Dissipation of Energy is effectively solved, reduction downstream river course, which is put, rushes engineering measure, saves quantities.
Embodiment one
As shown in Figure 1 and Figure 2, Energy Dissipation Modes in herein described sluice, including surface spillways, down stream bank, lock chamber.
Checked the floods down and let out by table gate hole, lower flood discharge water directly falls into downstream behind table Kong Yan faces by falling bank
Inside lock chamber, fall different tonifying Qi spaces that indent or non-indent be set of the bank lower part according to flood discharge flow, according to hydraulics meter
The air compensation for determining to need is calculated, tonifying Qi is carried out from gate pier or other parts by the way of pre-buried blowdown pipe, supplements tracheae
The gross area determines that blowdown pipe can be circular or other shapes according to benefit amount, mends the position of flue outlet with higher than downstream
Peak level is condition, selects circuit as short as possible.
