One-sided Main Corridor road-horizontal gallery-topmast hole ship lock dispersed delivery system
Technical field
The utility model relates to a kind of filling-emptying system of lock, especially a kind of ship lock dispersed delivery system.
Background technology
The conventional filling-emptying system of lock comprises:
1, end filling and emptying system
End filling and emptying system can be divided into short-culvert conveyance, directly utilize gate water delivery and combined type water delivery, and comprises following content respectively: (1) short-culvert conveyance comprises without energy dissipating room, has water delivery under energy dissipating room and sill;
(2) under directly utilizing gate water delivery to comprise triangual lock gate crack between a door and its frame, plane gate door and gate is opened wicket water delivery;
(3) combined type water delivery is made up of certain two kinds of water delivery pattern above-mentioned.
2, dispersed delivery system
Dispersed delivery system can be divided into following three major types according to water delivery waterpower feature and layout pattern.
The first kind comprises following pattern:
(1) lock wall gallery road collateral hole water outlet;
(2) lock wall gallery road branched hole water outlet;
Equations of The Second Kind comprises following pattern:
(1) top, pocket floor gallery road, the water outlet of collateral hole;
(2) gallery road and the sectional water outlet of gallery road, pocket floor under sill;
(3) lock wall gallery road horizontal gallery in the middle part of lock chamber props up hole water outlet;
(4) lock wall gallery road props up hole water outlet through lock chamber stage casing import longitudinal and transverse gallery;
(5) lock wall gallery road props up the water outlet of gallery two section through lock chamber center inlet horizontal flow pocket floor;
3rd class comprises lock wall gallery road and vertically shunts pocket floor through lock chamber center inlet and prop up gallery two section water outlet and the water outlet of gallery four section is propped up in pocket floor;
Because ship lock present position land used is nervous, length direction, width size all limit very strict.Because end filling and emptying system needs the colliding energy dissipation section of calming arranging certain length, by the restriction of ship lock length, eliminate the possibility that end filling and emptying system is set, so adopt dispersed delivery system.At present, all ship lock all adopt and are arranged symmetrically with gallery, due to the restriction by width, one-sided gallery system must be adopted: " a kind of one-sided Main Corridor road-horizontal gallery-topmast hole ship lock dispersed delivery system " is compared with traditional water-carriage system, can significantly save the area, save construction investment, can the set goal be reached again simultaneously.

Detailed description of the invention
As shown in Figure 1, a kind of one-sided Main Corridor road-horizontal gallery-topmast hole ship lock dispersed delivery system, is made up of water-carriage system inlet/outlet 1, leading portion culvert 2, Main Corridor road entrance 3, service valve 4, Main Corridor road 5, horizontal gallery 6, topmast weep hole 7, draining pump sump 8, catch pit 9, aqueduct, return valve, close-up valve.
Horizontal gallery 6 is arranged on lock chamber bottom surface, is uniformly distributed topmast weep hole 7 in horizontal gallery 6, and horizontal gallery 6 rear end is communicated with Main Corridor road 5, and Main Corridor road communicated drainage pump sump 8, has catch pit 9 on the left of draining pump sump 8.Main Corridor road 5 connects Main Corridor road entrance 3 by service valve 4, and Main Corridor road entrance 3 connects leading portion culvert 2 and water-carriage system inlet/outlet 1.
Water-carriage system of the present utility model is arranged:
Water-carriage system inlet/outlet 1 section height 2.5m, wide 6.5m, and be provided with trashrack; The smooth grizzly bar that trashrack adopts rectangle, wedgewise is all done at two ends, thick 6mm, spacing 30mm.The maximum mean velocity in section in water inlet of water-carriage system is about 0.31m/s.
Leading portion culvert 2, Main Corridor road 5 entrance have sudden enlargement one place, sudden contraction two place; The forward and backward cross-sectional area of expansion place 10.5m respectively
2and 12.0m
2, the forward and backward cross-sectional area in contraction place is respectively 16.25m
2(western ship lock), 10.5m
2and 12.0m
2, 5.0m
2.Have three place's corners to be the elbow portions of 90 ° in gallery, the place's of curving gallery bending radius of axis is respectively 1.0m, 2.0m, 2.25m.
Service valve 4 is arranged in Huangpu River lowest navigable stage (0.90m) below, and all floods, and its elevation, between-2.10 ~ 0.05m, can meet the requirement of valve working condition.
After service valve, Main Corridor road 5 (1) adopts and does not expand pattern; Main Corridor road section height 2.0m, wide 2.5m, respectively long 42.5m, be arranged in lock chamber east side lock wall.
Horizontal gallery 6 (22) is uniformly distributed along Main Corridor road; Horizontal gallery section height 0.5m, wide 0.5m, spacing 1.1m, be arranged in bottom lock chamber.
Consider the impact of Sediment Siltation, for the benefit of reduce the slough in lock chamber, water-carriage system adopts horizontal gallery topmast hole water outlet; Establish 12 holes above every bar horizontal gallery, on horizontal gallery, vertical topmast hole delivery port throat opening area Parallel to the flow direction reduces gradually, and topmast bore dia Parallel to the flow direction is followed successively by Φ 220, Φ 200, Φ 180 and Φ 160mm; Topmast weep hole is uniformly distributed in lock chamber bottom surface, coincides with the center of lock chamber area.
During lock chamber draining, water body is by the pumping of submersible axial flow pump group, and through topmast hole ,-horizontal gallery-Main Corridor road, enters draining pump sump, arranges 3 submersible axial flow pumps in draining pump sump.Water body is pumped to the catch pit of draining pump sump north side by submersible axial flow pump group, through aqueduct, under return valve and close-up valve regulated, reverse water delivery autonomous gallery entrance-leading portion culvert-water-carriage system water inlet enters basin, or urgent draining enters Huangpu River through aqueduct.
As shown in Figure 2, water-carriage system workflow of the present utility model:
During operation, water body is Inner eycle between basin-ship lock substantially; When speedily carrying out rescue work or safeguard, water body enters Huangpu River from basin through ship lock.Lock chamber is poured water, and (forward water delivery or basin normal discharge) adopts flow by gravity, and lock chamber draining (reverse water delivery or the urgent draining of basin) adopts the pumping of submersible axial flow pump group, and idiographic flow is as follows:
(1) forward water delivery A (basin → lock chamber)
During operation, water body under gravity, enters (going out) mouth of a river-leading portion culvert-Main Corridor road entrance-operating valve gate segment-Main Corridor road-horizontal gallery from yacht basin through water-carriage system, enters lock chamber from topmast weep hole.
(2) reverse water delivery B (basin ← lock chamber)
During operation, water body is by the pumping of submersible axial flow pump group, from lock chamber through topmast hole-horizontal gallery-Main Corridor road-draining pump sump (submersible axial flow pump group)-catch pit-aqueduct-return valve (open mode)-Main Corridor road entrance-leading portion culvert, enter yacht basin from water-carriage system water inlet.
(3) basin normal discharge C (basin → lock chamber → Huangpu River)
Basin desilting safeguards that should be selected in Huangpu River water level carries out lower than during basin base top elevation, and water body enters lock chamber (flow process is with " forward water delivery ") from basin gravity flow, and from ship lock flood tide gate place (open mode), gravity flow enters Huangpu River.The urgent draining D of basin (basin → lock chamber → Huangpu River)
When running into dangerous situation, if Huangpu River water level is lower than basin base top elevation, then adopt free-draining (flow process is with " basin normal discharge "); Otherwise water body is discharged by the pumping of submersible axial flow pump group.
Water body is from yacht basin-service valve and inner gate place (open mode)-lock chamber, through topmast hole ,-horizontal gallery-Main Corridor road-drip chamber-draining pump sump (submersible axial flow pump group)-catch pit-aqueduct-close-up valve (open mode), enters Huangpu River through aqueduct.
