Lock wall staggered layer short gallery side branch hole water delivery anti-salty ship lock

Abstract

The invention discloses a lock wall staggered layer short gallery side branch hole water delivery anti-salty ship lock, which belongs to the crossing field of ship lock engineering and ecological protection, and comprises an upper lock head, a lock chamber, a lower lock head, an upper gate and a lower gate, a short irrigation gallery communicated with an outer estuary of the upper gate through an irrigation valve is arranged in the lock wall, close to the upper lock head, of the lock chamber, and a short drainage gallery communicated with an outer estuary of the lower gate through a drainage valve is arranged in the lock wall, close to the lower lock head, of the lock chamber; the gate wall is provided with a gate chamber, an irrigation side branch hole communicated with the irrigation short gallery and a drainage side branch hole communicated with the drainage short gallery, the irrigation side branch hole and the drainage side branch hole are arranged in a staggered mode relative to the height direction of the gate wall, and the irrigation side branch hole is higher than the drainage side branch hole. According to the anti-salty ship lock, a lock wall staggered layer short gallery side branch hole water conveying structure is ingeniously designed, the layering characteristic of density flow is fully utilized through the water conveying hydraulic structure of the ship lock, water is controlled with water, and the more effective anti-salty effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of ship lock engineering and ecological protection, and relates to an anti-salt ship lock for water delivery through side branch holes of short corridors with staggered layers of lock walls. Background technique [0002] The main inland river estuaries along the coast of my country are almost all equipped with discharge and tide-proof sluices. In order to solve the navigation problem after the estuary is set up, it is generally necessary to build ship locks. However, during the operation of the ship lock, seawater intrusion will cause the mixing of freshwater and saltwater, polluting the freshwater area. This process may affect the inland water quality within tens of kilometers, seriously affecting the industrial and agricultural production and people's life along the river. The main forms of seawater intrusion in the ship lock of the estuary are hyperpycnal flow, water level difference, and salt leakage of ...

AI Technical Summary

Problems solved by technology

In order to solve the problem of seawater intrusion in the ship lock at the estuary, the current anti-salt measures for the ship lock project mainly include the air curtain method, the salt pit method, the replacement method and the liftable salt water box method, but these measures are complicated to operate and require a large amount of work , and high operating costs
