Background technique
Spillway is a kind of discharge structure most commonly seen in key water control project, is mainly used for leading off and plans that storage capacity cannot
The flood of receiving, with flood-protection overflow dam crest influence dam safety.Spillway is divided by its structure type: Proper channel spillway, side
Slot spillway, shaft spillway, siphon spillway.
Commonly Proper channel spillway and side channel spillway at present, Proper channel spillway and let out fluted shaft line at overflow weir axis
It is orthogonal, cross sluice stream it is consistent with slot axis direction is let out, usually by flume, control section, let out slot, energy dissipation below spillway section and tailwater channel group
At.Compared with side channel spillway, Proper channel spillway structure is simple, and flow condition is good, and flood carrying capacity is strong, and engineering safety is reliable, applies
Work management is more convenient.Side channel spillway, overflow weir substantially arrange that water flow leaks into big with weir axis from overflow weir along contour
After causing parallel side channel, flow direction makees nearly 90 ° of turnings, then is let out slot or tunnel flows to downstream, usually by overflow weir, side channel, sluicing
Road and energy dissipation below spillway section composition.Compared with Proper channel spillway, side channel spillway earthwork is small.Traditional Proper channel spillway is when two
Bank topography is higher, and when bank slope is steeper, excavated volume is big, while in order to keep water flow smooth, must be set up flume, project amount compared with
Greatly, therefore there are biggish rooms for improvement.
Utility model content
The purpose of this utility model is that being directed to the defect of the spillway prior art, a kind of novel spillway control section is provided
Structure.
The utility model is realized in this way:
A kind of novel spillway control segment structure, overflow weir and its downstream direction connection including face dam side is arranged in
Let out slot；It the overflow weir and lets out slot and is equipped with the U-type groove being made of abutment wall and bottom plate；Overflow weir abutment wall and let out trough rim wall and side
Filler is equipped between slope；Wherein the filler between the overflow weir abutment wall and side slope of overflow weir be overflow weir abutment wall and side slope it
Between concrete backfill, let out the filler between trough rim wall and side slope and be divided into upper layer and lower layer, lower layer be let out trough rim wall and side slope it
Between concrete backfill, upper layer be let out between trough rim wall and side slope rubble backfill.
Wherein, overflow weir is practical weir.
Further, the concrete backfill between overflow weir abutment wall and side slope and the rubble let out between trough rim wall and side slope return
Filling is filled out to dam access bridge elevation.
Further, single, spacing is used to constitute side slope anchor for the 600kN of 6m grade anchorage cable anchoring at side slope backfill elevation
Gu.
Compared with prior art, the utility model structure is simple, and flow condition is good, and flood carrying capacity is strong, and engineering safety is reliable,
It is adaptable to landform, it is convenient for project playout, reduces slope excavating amount, saves construction investment, construction management is more convenient, right
It is particularly suitable in the water-control project of some complicated topographical conditions.
