Description
Technical field
The utility model is related to hydraulic engineering field, more particularly to a kind of stiling basin water sealing structure and use the sealing knot
The stiling basin of structure.
Background technology
Stiling basin refers to produce the efficiency facility of underflow type hydraulic jump in discharge construction downstream, lets out torrent under can making and become rapidly
For unhurried current, typically the kinetic energy of the lower stream that sluices can be eliminated 40%~70%, and protection-apron length can be shortened, be a kind of effectively economical
Energy-dissipating installation.At this stage with the rise of China's water conservancy projects, general stiling basin is divided into descending manner, buffle sill formula and composite type
Deng.
Descending manner is to reduce the stiling basin that protection-apron elevation is formed, and to increase Tailwater Depth, torrent is let out under promoting in pond
Produce underflow type hydraulic jump.In order to ensure to occur without the remote hydraulic jump design pond depth driven formula hydraulic jump, often slightly flooded by being formed in pond.
Buffle sill formula is on protection-apron（Typically in end）The stiling basin for setting buffle sill and being formed, is used for hydraulic jump degree of flooding and slightly feels not
Foot, or excavate the situation that stiling basin is had any problem.Composite type is the stiling basin for not only having reduced protection-apron height but also having set buffle sill and being formed,
It is used for Tailwater Depth and carries water altogether with second deep to differ larger situation.
Authorization Notice No. is CN103397619B Chinese patent document《Disperse the height bank stiling basin of energy dissipating along journey》In
A kind of stiling basin of descending manner is disclosed, includes inlet segment, stiling basin internal partition wall, the stiling basin to connect with inlet segment of current
End sill and the protection-apron to connect with stiling basin end sill.It is in the portion that height bank stiling basin bank discharge orifice low with current inlet segment connects
Position is alternate to be provided with partition wall, and partition wall two sides use arc since the top of the low bank aerial drainage hole exits of current inlet segment with low bank
Changeover portion is in smoothing junction.By above-mentioned setting, current from inlet segment enter stiling basin when can be in height bank and the work of barricade
With the concentrated stress acted on force reduction pool bottom of lower elimination early stage, reach the effect for disperseing energy dissipating along journey.
But as shown in above-mentioned scheme, current are flowed into stiling basin at a high speed from inlet segment, if not to the bottom plate of stiling basin
Do corresponding sealing to set, high-velocity flow can be pierced directly under bottom plate, and bottom plate will bear larger uplift pressure and fluctuation pressure, can
Bottom plate can be caused to be started or by more serious erosion damage, therefore the water sealing structure of stiling basin directly influences the power that disappears
The service life in pond, it is particularly important in stiling basin structure.
