Water-saving layout structure of parallel double-line huge navigation lock water conveyance system, and water conveyance method of water-saving layout structure

Abstract

The invention provides a water-saving layout structure of a parallel double-line huge navigation lock water conveyance system, and a water conveyance method of the water-saving layout structure, and belongs to the technical field of navigation building hydraulics and navigation lock water conveyance system hydraulics. The water-saving layout structure comprises two parallel navigation locks, wherein longitudinal water conveyance galleries are arranged at the bottoms of lock chambers of the navigation locks; water inlets and water outlets are formed in the upstreams and the downstreams of the longitudinal water conveyance galleries, and are communicated with upstream and downstream navigation approach channels; the middle parts of the longitudinal water conveyance galleries of the two lock chambers are connected by two transverse communicating galleries; valves for controlling the on-off between the two longitudinal water conveyance galleries are arranged on the transverse communicating galleries; a plurality of transverse water conveyance branch holes are formed in the two sides of the longitudinal water conveyance galleries, and are communicated with the lock chambers of the navigation locks; and at least one barrier is arranged in the length directions of the lock chambers on the outer sides of the transverse water conveyance branch holes. The water-saving layout structure and the water conveyance method have the significant advantages that the operation water consumption of the navigation locks is saved; each stage of working head is lowered; operation conditions of water conveyance valves are improved; water flow conditions of the lock chambers and the navigation approach channels are improved; and the construction is facilitated.

Description

technical field [0001] The invention relates to a water-saving layout structure and a water delivery method of a parallel double-line water delivery system suitable for a large ship lock with a large water head or a large plane scale at one time, and belongs to the hydraulics of navigable buildings and the water delivery system of a ship lock The field of hydraulic technology. Background technique [0002] my country is a country with severe drought and water shortage, and the shortage of water resources has begun to affect the development of water transportation in our country. The latest industry research report "Innovations in Navigation Lock Design" published by the International Association of Shipping in 2009 to guide the design of future ship locks suggests that for large ship locks (the length of the lock chamber is greater than 200m and / or the water head of the lock is greater than 15m), even if the design is the most economical In addition to an efficient water de...

Problems solved by technology

This arrangement has the obvious advantage of saving water consumption in the operation of the lock, but its disadvantage is that the area occupied by the lock and the amount of work will be increased due to the construction of the water saving pool.

The double-line ship locks arranged side by side, especially the giant double-line ship locks arranged side by side with a huge vo...
