Description
Technical field
The utility model relates to the tidal soft foundation layout of sluice form of strand in hydraulic engineering, particularly relates to a kind of layout of sluice form without aileron.
Background technology
According to sluice specification, it is generally absorption basin, protection-apron, apron, anti-scour trench that conventional sluice lock chamber upstream and downstream are arranged, left and right generally adopts upright aileron.The projected length that aileron flows to downstream should be more than or equal to absorption basin length, and wall crest elevation should higher than worst operational water level, flows and overflows back absorption basin by wall top, add large discharge per unit, affect effect of energy dissipation to prevent lower sluicing.If adopt splay aileron, its planar diffusion angle is generally 8 ° to 12 °.
Because sluice basis, strand is mostly soft foundation or Muddy Bottoms tidal land, aileron wall top generally should exceed design water level, and load is comparatively large, and basis needs to adopt pile foundation process, and after wall, the backfill cubic meter of stone is connected with two sides, and aileron is subject to differential settlement and produces distortion; In addition, strand sluice is generally low-head operating, and belong to Low Froude numbers Dissipation of Energy, energy dissipation rate only has about 15%, and the initial velocity of bed material is general all very low, reaches 0.80m/s even lower, is very easily washed.
The tidal soft foundation sluice in strand, the left and right sides is connected with seawall or dyke mostly, upstream and downstream quaywall structure, traditional design generally adopts upright aileron, and near water, a side block is native in side, easy generation differential settlement, thus cause distortion, when being out of shape serious, can crack be produced, cause leakage passage, institute thinks minimizing differential settlement, need carry out based process to backfill certain limit after wall, causes investment to increase; Invariably cannot will there is scour phenomenon in apron end and anti-scour trench position and bed surface and concrete binding site, wherein near mouth door arranged on left and right sides coiled hair, scour is more serious, and this phenomenon certainly will increase the foundation protection degree of depth near apron end and aileron coiled hair.Once wash away, the easy landing of jackstone even collapses upon itself in anti-scour trench, severe patient jeopardizes the stable of apron, protection-apron even lock chamber.Therefore, in the actual motion of coastal many engineerings, be all often constantly add throwing block stone to safeguard every year, expense is huge.Therefore for avoiding differential settlement, reaching good dissipation and scouring effect, reduce investment outlay, a kind of novel layout of sluice form need be sought.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, proposes a kind of impact and the downstream scour that both can avoid differential settlement, significantly can reduce again construction investment, reduce the novel without aileron layout of sluice form of difficulty of construction.
The technical solution adopted in the utility model is: a kind of without aileron layout of sluice form, include lock chamber, quaywall, dissipation and scouring facility, lock chamber left and right side is furnished with quaywall, lock chamber upstream and downstream are furnished with dissipation and scouring facility respectively, it is characterized in that: be positioned at left bank, sluice upstream, sluice upstream right bank, Downstream of Sluice left bank, Downstream of Sluice right bank arbitrary place everywhere or the aileron cancellation at a few place, change into and ramp type bank protection is set, bank protection leans on quaywall layout and to external diffusion, bank protection adopts arc form or broken line form or circular arc in conjunction with broken line form to external diffusion.Be positioned at left bank, sluice upstream, sluice upstream right bank, Downstream of Sluice left bank, Downstream of Sluice right bank arbitrary place everywhere or the aileron cancellation at a few place, change the form arranging ramp type bank protection into comprise: be positioned at left bank, sluice upstream, sluice upstream right bank, Downstream of Sluice left bank, Downstream of Sluice right bank arbitrary place everywhere or wantonly two places or wantonly three places or aileron everywhere and cancel, change into and arrange ramp type bank protection.
As preferably, the absorption basin in the dissipation and scouring facility in described lock chamber downstream adopts concrete platform to be connected with the bank protection being positioned at downstream.
As preferably, the border of the absorption basin in the dissipation and scouring facility of described lock chamber upstream and downstream adopts the Plane Angle of 8 ° to 12 ° to external diffusion.
As preferably, the border of the absorption basin in the dissipation and scouring facility of described lock chamber upstream and downstream adopts the Plane Angle of 10 ° to external diffusion.
The beneficial effects of the utility model are:
1) do not establish aileron, soft foundation, without the need to pile foundation process, reduces civilwork engineering quantity, decreases working procedure, reduces difficulty of construction, shortens the duration, saves investment.
2) do not establish aileron, the cross-section of river is expanded, after water flows out lock, unfettered, can spread immediately, through energy dissipating and the adjustment of absorption basin, similar with the original state river mouth earial drainage that goes to sea, reduce exit velocity, taper scour phenomenon disappears, and reduces near apron end and coiled hair and washes away.
3) two sides are without aileron, adopt ramp type bank protection, and later maintenance maintenance is convenient.
4) because there is obvious shortening the civil engineering structure construction period, for engineering is completed ahead of schedule, play water drainage flood control as early as possible, create advantage.
