The utility model realizes that the technical scheme of above utility model purpose is: the water-saving arrangement that the huge filling-emptying system of lock of a kind of two-wire arranged side by side is provided, comprise two ship lock that are arranged in juxtaposition, the lock chamber bottom of described ship lock all arranges longitudinal culvert, water inlet is set respectively in the upstream and downstream of described longitudinal culvert and delivery port communicates with the upstream and downstream approach channel, the longitudinal culvert of two lock chambers middle part is connected by two cross connection gallerys, is provided with break-make between two vertical water delivery corridors of valve control at described cross connection gallery; The lock chamber that the both sides of described longitudinal culvert all arrange a plurality of horizontal water delivery Zhi Kongyu ship lock communicates, and along the lock chamber length direction gear sill is set at least one outside the hole is propped up in described horizontal water delivery.
The technical scheme that the utility model further limits is: the huge filling-emptying system of lock water-saving of aforementioned two-wire arranged side by side arrangement, each horizontal water delivery of first lock chamber of described cross connection gallery upstream is propped up hole area and is equated, each horizontal water delivery of second lock chamber in described cross connection gallery downstream is propped up hole area and is equated, the Area Ratio that the hole is propped up in the horizontal water delivery that the area in hole and second lock chamber are propped up in the horizontal water delivery of described first lock chamber is 1.2:1.
The water-saving arrangement of the huge filling-emptying system of lock of aforesaid two-wire arranged side by side, described gear sill are provided with twice altogether, in the sill bottom of keeping off together near described water delivery gallery water hole is set, formation twice energy dissipating open ditch of ship lock between described gear sill and the gear sill and between gear sill and the water delivery gallery.
The water-conveying method of the huge filling-emptying system of lock water-saving of a kind of two-wire arranged side by side arrangement, may further comprise the steps: (1) is with two mutual water deliverys of the ship lock that is arranged in juxtaposition, be specially the valve of at the uniform velocity opening on the cross connection gallery, two ship lock carry out mutual water delivery by being communicated with gallery first; (2) when the head difference between two ship lock that are arranged in juxtaposition be reduced to residual water level between two ship lock poor for maximal head 26%～30% after, at the uniform velocity close and be communicated with the gallery water-delivery valve and stop two water deliverys between ship lock; That (3) opens simultaneously each ship lock fills, lets out valve to finish remaining water delivery process.
The water-conveying method of the huge filling-emptying system of lock water-saving of aforesaid two-wire arranged side by side arrangement, the valve on the described cross connection gallery at the uniform velocity opening speed is 2m/min, the valve on the described cross connection gallery at the uniform velocity closing velocity is 1.0～1.5m/min.
Further, the water-conveying method of the huge filling-emptying system of lock water-saving of aforesaid two-wire arranged side by side arrangement, between described two ship lock that are arranged in juxtaposition residual water level poor for maximal head 28% the time begin to close valve on the described cross connection gallery.
The beneficial effects of the utility model are: (1) saves ship lock operation water consumption, can protect and utilize water resource, reduce dry season the boats and ships lockage with the contradiction of generating water; (2) reduce lock valve working head, easier solution ship lock valve knowledge question of water conservancy; (3) reduce maximum water delivery flow, be convenient to improve lock chamber and approach channel flow condition; (4) compare with the isolated operation of every line ship lock, can simplify the water-carriage system of ship lock and arrange that constructability is safeguarded.
Thereby the utlity model has and save ship lock operation water consumption, reduce the remarkable advantages such as every level work head improves the water-delivery valve service condition, improves lock chamber and approach channel flow condition, constructability.
