Abstract
The invention relates to a non-orthogonal arrangement method on a ship lock dam and belongs to the field of water conservancy project integral arrangement, in particular to a method for arranging a ship lock at the upstream of a dam and adopting non-orthogonal arrangement between the ship lock and a dam axial line. The method comprises the steps of determining the necessary conditions of the non-orthogonal arrangement method on the ship lock dam and determining the basic design parameters of the ship lock and upstream and downstream approach channels. The new arrangement method is provided for the current conditions of ship lock arrangement difficulty and ship lock additional building of the built projects, and in addition, a design parameter obtaining method of the method is also provided.
Description
Technical field
Non-orthogonal arrangement method on ship lock dam of the present invention, belongs to hydraulic engineering integral arrangement field, especially a kind of method of nonopiate layout that navigation lock disposal is adopted between upstream, dam and ship lock and the axis of dam.
Background technology
In < < ship lock general arrangement standard > >, clearly stipulate that " lock chamber should be arranged in water retaining structure downstream." in navigation key water control project is arranged, more common arrangement form is the downstream at the axis of dam by navigation lock disposal, and ship lock and the axis of dam be in orthogonal form, and can be called orthogonal method under dam here.The advantage of arranging is like this: 1, navigation lock disposal is in axis of dam downstream, generally under dam, water level is low compared with water level on dam, and because ship lock will be connected water levels of upstream and downstream, so navigation lock disposal contributes to reduce lock chamber abutment wall elevation in downstream, save construction volume, save investment; 2, ship lock and the axis of dam layout that is orthogonal, generally axis of dam upstream and downstream current are perpendicular to the axis of dam, and therefore, when ship lock and axis of dam quadrature arrangement, upstream and downstream flow velocity is basic parallel with ship lock, and flow field is conducive to ship and passes in and out smoothly ship lock.
But under dam there is following shortcoming in orthogonal method:
1, with a varied topography when downstream, after being not suitable for building ship lock or having built ship lock, downstream river course curtailment when building approach channel, cannot be built navigation engineering;
2, for built hydraulic engineering, when axis of dam upstream and downstream current and the axis of dam are when non-orthogonal, if newly-built ship lock and axis of dam quadrature, outlet area of ship lock velocity flow profile will become with ship lock a natural angle, can not meet the ship requirement of opening the navigation or air flight safely.
Summary of the invention
The object of the invention is, for above defect, to propose a kind of non-orthogonal arrangement method on ship lock dam, the navigation facilities meeting under hinge arrangement condition complex situations is arranged needs.
Particularly the present invention includes following content:
1, the necessary condition of non-orthogonal arrangement method on ship lock dam:
1a, ship lock and power station are arranged apart; If ship lock layout adjacent with power station found in inventor's experimental study, because power plant tail water effect downstream all can not meet the navigation condition of regulation and stipulation in remote, so ship lock and power station arranged apart be the primary condition of arranging on use ship lock dam.
1b, sluice gate designs the maximum navigation discharge that minimum standard-sized sheet discharge is greater than ship lock; When ship lock and power station are arranged apart, sluice gate will layout adjacent with ship lock, because the bleeder quantity of sluice gate inevitably can produce in upstream port door district larger transverse flow speed when larger, now for descending ship, it is ineffective that ship's speed and flow velocity acting in conjunction meeting cause ship to control, to sluice gate motion, for guaranteeing the descending ship safety in upstream, inventor points out only at sluice gate, to design when minimum standard-sized sheet discharge is greater than ship lock design maximum navigation discharge and just can use this method for arranging;
1c, when sluice gate sluices, current main flow direction and the axis of dam angle of cut of upstream arrangement ship lock one side are larger, if ship lock is arranged perpendicular to hinge when sluice gate sluices, Kou Men district flow velocity cannot meet in < < ship lock general arrangement standard > > the regulation about Kou Men district flow velocity;
2, determine the basic design parameters of ship lock;
2a, lock chamber abutment wall crest level is higher than upstream design flood level;
2b, upper tail-bay elevation is not less than lock chamber abutment wall crest level;
3, determine the basic design parameters of upstream and downstream approach channel:
3a, upper approach is littoral to be arranged;
3b, sealing guide wall is set, till sealing guide wall length extends to Kou Men district flow velocity and meets < < ship lock general arrangement standard > > and require between lower approach and sluice gate.
The invention has the advantages that:
For navigation lock disposal is difficult and built engineering increasing boatbuilding lock has proposed a new method for arranging, and the design parameters acquisition methods of this method has been proposed.
Accompanying drawing explanation
The nonopiate traditional lock chamber layout pattern schematic diagram of Fig. 1 existed junction current and hinge;
Nonopiate layout and arranging the navigation channel schematic diagram thereof on Fig. 2 lock chamber dam.
The specific embodiment
As shown in Figure 1, ship lock 1 is arranged apart with power station 3, between ship lock 1 and power station 3, it is sluice gate 2, due to flow direction and hinge obviously nonopiate, so under taking ship lock dam during arrangement, its upper approach 4 Kou Men district flow velocitys can not meet navigation requirement, and lower approach 5 Kou Men district flow velocitys can not meet navigation requirement, therefore tackle this design and modify.
Ship lock 1 is arranged apart with power station 3, and sluice gate designs minimum standard-sized sheet discharge and is greater than Aided Locked Design maximum navigation discharge; When sluice gate sluices, current main flow direction and the axis of dam angle of cut of upstream arrangement ship lock one side are greater than 120 degree; If ship lock is arranged perpendicular to hinge when sluice gate sluices, Kou Men district flow velocity cannot meet in < < ship lock general arrangement standard > > the regulation about Kou Men district flow velocity.
Therefore be revised as on ship lock dam and arrange: lock chamber abutment wall 6 crest levels are that 56m is higher than upstream design flood level 55m; Upper tail-bay elevation 56.5m; Upper approach 4 is littoral to be arranged, sealing guide wall 8 is set, till sealing guide wall 8 length extend to Kou Men district flow velocity and meet < < ship lock general arrangement standard > > and require between lower approach and sluice gate.
