Embodiment
Describe the embodiment of patent of the present invention in detail below in conjunction with accompanying drawing, the protection domain of patent of the present invention is not
It is limited only to the description of present embodiment.
The embodiment provides a kind of parallel pipe laying type permeable spur, it arranges top view and sectional view such as Fig. 1
With shown in Fig. 5.This pipe laying type permeable spur that interlocks includes concrete sheet-piling 1, the dam body 2 by being embedded with small-caliber steel pipe 3, abutment and connected
Binder 4 and abutment base plate 5.
Dam body 2 is entity structure, and abutment is semicircle, overall in round table-like.The abutment contacts smooth with the water surface, excessively level
It is suitable.Sheet pile 1 is concrete sheet-piling 1, and it is arranged in parallel in upstream and downstream side and the axis of dam, and dam heel and dam site connect.At abutment
Vertical axis of dam arrangement, and abutment circular arc substrate and sheet pile 1 are tangent, vertically adjacent to sheet pile between connected by abutment linking beam
4, abutment linking beam is arranged at the bottom of abutment base plate 5.Joint 6 is left on concrete sheet-piling top, and sheet pile passes through with the groynes dam foundation
Concrete cast-in-situ is connected.Wherein, abutment linking beam 4 is connected with two adjacent vertical plates stake 1 in 45 degree of angles.Abutment base plate 5 and plate
Stake 1 and abutment linking beam 4 are connected by concrete cast-in-situ, so, and groynes dam body 2 and dam foundation sheet pile 1 be firm, and to be combined into one whole
Body, can effectively be less than to flow the scour around for the dam foundation, improve groynes overall stability and durability.
The steel pipe 3 buried in dam body 2 arranges that the diameter of steel pipe 3 is in 0.5m between 1m approximately along Parallel to the flow direction.The steel
The axis of pipe 3 is projected with Parallel to the flow direction in 10 ° to 30 ° of angle in the horizontal plane, and the axis of the steel pipe 3 is in perpendicular
Interior projection and horizontal direction are in the angle between 5 ° to 20 °.One group two-by-two of the steel pipe 3, is regularly distributed in "eight" shape
In dam.Every group of steel pipe about 3 parallel layered laminate bury.When to flow, a part of current are stopped by groynes dam body 2, pass through abutment
Bypass, another part current import groynes downstream by steel pipe 3.Due to steel pipe, group carries the elevation angle, and every group of steel pipe 3 is in water
Projected in plane in "eight" shape wherein, in one group of steel pipe, the steel pipe opening horizontal range of upstream side two is more than the steel pipe opening of downstream two
Horizontal range, sweeps along the current of silt to enter after the pipe laying with positive slope, velocity in pipes slows down.Gushed in current from the downstream mouth of pipe
After going out, the current in one group of steel pipe are after collision efficiency, and water velocity is greatly reduced, so that sediment settlement, alluvial.Steel pipe
3 mouths of pipe are relatively low in upstream face side, higher in downstream face side, and the upstream face spout tops of steel pipe 3 should be greater than away from water surface depth
Critical submergence depth, while downstream face steel pipe nozzle bottom position should be at least above more than dam foundation face 1m, wherein, critical depth isD was the internal diameter of water steel pipe, unit m；V is the maximal rate that place river is likely to occur, m/s；C is with entering
The relevant parameter of mouth of a river geometry, typically takes 0.55.So produce in upstream and downstream side to threaten groynes structure
Air-breathing funnel-form whirlpool.
With reference to existing construction technology and material, sheet pile 1 is generally reinforced concrete sheet pile.Using anti-near the steel pipe
Wearability is rushed preferably to adulterate flyash concrete.
In summary, the present invention passes through the steel-tube construction that multigroup connection is buried in groynes dam body and is arranged in parallel, steel pipe
Axis is projected in the horizontal plane has certain angle with the axis of dam, is distributed, is allowed to compared to common permeable spur in " eight " font,
The present invention can be more preferably to saturating dam current energy dissipating, and stationary flow weakens whirlpool behind dam, while reducing groynes downstream bottom flow velocity, promotees
Enter sediment settlement and make beach to deposit.Pipe laying type permeable spur of the present invention, the sheet pile foundation put by three bread cloths and linking beam
Cast-in-place connection, substantially increases resistance to overturning and durability of the groynes in dynamic water.
