Technical field
Hydraulic and Hydro-Power Engineering flood discharge preventing atomization technical field is the utility model is related to, being specifically related to one kind can be freely lifted
The permeable cloth of double-deck preventing atomization.
Background technology
In Hydraulic and Hydro-Power Engineering outlet structure escape works（Particularly high dam）During aerial drainage, in the regional area of downstream often occur compared with
Large-scale rainfall and spray diffuse phenomenon, and engineering circles are referred to as flood-discharge atomizing.Due to the rainfall intensity (raininess) of its initiation
Generally up to hundreds if not thousands of more than mm/h, the raininess value (11.67mm/h) of extra torrential rain considerably beyond in natural precipitation,
So as to Hydraulic and Hydro-Power Engineering downstream bank stability, main structures normal operation, traffic safety and surrounding environment produce compared with
Big harm.The engineering harm that flood-discharge atomizing triggers reminds us to be fully recognized that flood discharge mist in the project planning an design stage
The harmfulness of change, and its negative effect is avoided or reduced by effective preventive means.
Currently used energy dissipation type has：Flip trajectory bucket, disspation through hydraudic jimp, submerged bucket dissipator and Dissipation Energy in Solid Bucket, these energy dissipatings
Form can obtain good effect of energy dissipation, while also result in more serious fogging problem, particularly flip trajectory bucket.Conventional water
Sharp engineering is mostly by reinforcing downstream side slope（Anchor cable and concrete patch slope）To reduce the harm of atomization zone, these methods are deposited
It is complicated in construction, it is with high costs, waste the shortcomings of serious.During high dam flood discharge, current are exported by wasteway and impact disappears
During power bottom of pond portion's scour hole, atomization most serious caused by its water house, if can be in flood discharge overall process by being arranged above being given up in water
Novel changable height and the permeable cloth of double-deck preventing atomization of variable incidence, can not only play the effect for mitigating flood-discharge atomizing degree, and
And arrangement is simple and convenient to operate, cost is cheap.
