Invention content
The purpose of the present invention is to provide duct Overflow Towers, are laid without selection in higher topographical.Overflow is prevented to send out
The penstock vibration problem that water hammering generates when raw improves the durability of overflow steel pipe.This overfall facility is provided simultaneously with waterpower
Energy dissipating acts on.
In order to achieve the above objectives, present invention employs following technical solution, duct Overflow Tower, including Box-shaped Drainage Culvert,
Overflow steel pipe, further includes tower foundation pedestal, inner cylinder tower body, outer barrel tower body, the lower port of the inner cylinder tower body and outer barrel tower body
Lower port links into an integrated entity structure with the tower foundation pedestal of lower section, and the inner cylinder tower body is integrally located inside outer barrel tower body, and
Form overflow ducts between the two, in the vertical through holes that the overflow steel pipe fastening is opened up in inner cylinder tower body, overflow steel pipe upper end
Above-mentioned overflow ducts are connected, overflow steel pipe lower end then connects water supply line, and water supply line is fastened on the horizontal stroke that tower foundation pedestal opens up
Into through-hole, the beginning of the Box-shaped Drainage Culvert is connected in the discharge outlet that outer barrel tower body bottom end opens up to be connected with overflow ducts.Institute
It states overflow steel pipe and at least sets one, the inner cylinder tower body is concrete structure, and outsourcing is in overflow outer wall of steel pipe.The tower foundation
Pedestal is the concrete structure of trapezoidal mesa-shaped, and outsourcing is in water supply line outer wall.Overflowing between the inner cylinder tower body and outer barrel tower body
Circulation road is provided with energy dissipating grid, and energy dissipating grid at least sets one layer.
The end of the Box-shaped Drainage Culvert connects antifreeze flap valve.
The outer barrel tower body upper port sets prefabricated cover board, and venthole is opened up on prefabricated cover board, connects snorkel.It is described outer
Cylinder tower body outer wall setting cat ladder.
Compared to the prior art, the invention has the advantages that：
1. overfall facility is laid directly to connect up threeway in the Vertical Square of main pipeline, without selection in higher topographical.
2. overfall facility is by vertical overflow steel pipe outsourcing 1m thickness armored concrete, it is therefore prevented that water hammer is made when overflow occurs
With the penstock vibration problem of generation, the durability of overflow steel pipe is improved.
3. an overfall facility is provided simultaneously with waterpower energy dissipating effect, flow carries out drop formula energy dissipating, and pass through two after overflowing
Grade grid reduces percussion of the high-velocity flow to armored concrete.
