Description
Technical field
It the utility model is related to water conservancy and hydropower construction engineering technical field, and in particular to a kind of sluice dissipation and scouring knot
Structure.
Background technology
In Hydraulic and Hydro-Power Engineering, outlet structure escape works are the keys for ensureing reservoir safety and giving full play to project benefit.Disappear
Can structure be outlet structure escape works important component, be responsible for the task for the partially or mostly water flow dynamic energy of dissipating, and can make
The current that energy dissipater releases current original with downstream river course, which obtain, to be properly connected；Need to consider during design it is lower sluice stream there may be
Cavitation corrosion, pulsation, vibration, the destruction such as wear, wash away.
Instantly when the stream that sluices uses disspation through hydraudic jimp, protection-apron (or one part) often makes stiling basin pattern, promotes high speed water
Stream produces hydraulic jump in the range of stiling basin, and because stressing conditions are complicated, protection-apron abuts lock chamber or dam body again, once destroy, directly
Gate dam safety is influenceed, therefore it is required that protection-apron has enough weight, intensity and impact-resisting wear-resisting ability, is ensured under external force not
Floated or destroyed by rush of water；Protection-apron is often built up with armored concrete, and protection-apron top layer and bottom arrange reinforcing bar in general, small-sized
Engineering also can only configure top layer reinforcing bar.In order to which the osmotic pressure under protection-apron is reduced or eliminated, in bottom making draining loaded filter, and
In the latter half of setting osculum of horizontal segment.Need to be separated with depression seam between protection-apron and lock chamber or dam body, aileron, it is uneven to adapt to
Sedimentation.When protection-apron is wider, also need to set the transverse joint of Parallel to the flow direction, its spacing is relevant with foundation condition；It is general not set vertically
The transverse joint of water (flow) direction, to ensure the resistance to overturning of protection-apron.
Stream also maintains certain complementary energy after protection-apron significantly energy dissipating, and the effect of apron seeks to eliminate current
Complementary energy, velocity flow profile is adjusted, water stream is uniformly diffused out, is allowed to approach with the streamflow regime of natural river course, is exempted from protecting riverbed
Washed away.
Energy dissipation by hydraulic jump is applicable to all kinds of outlet structure escape works of senior middle school's low water head, big-and-middle low discharge, and the Energy Dissipation Modes are over the ground
Matter condition requires low, good to tail water luffing adaptability, thus is used widely.But there is following ask in the protection-apron in energy dissipation by hydraulic jump
Topic：
(1) inside of protection-apron and apron is typically placed with some different boulders to carry out energy dissipating to current, works as head
When higher, apron front portion will bear higher flow velocity, it is prone to cavitation corrosion and abrasion, and the bulk of the inside of protection-apron and apron
Stone is also easily washed away by current, causes the overall energy dissipating of sluice unstable；
(2) due to the transverse joint of setting Parallel to the flow direction on protection-apron, the current of protection-apron are caused to easily infiltrate into pine below
In granular media, cause the loose media of landfill below gate dam to be washed away for a long time by current, the safety of gate dam can be directly influenced.
