A three-stage energy-dissipating ship compartment nested in a lock chamber of a ship lock and a ship lock-passing method

Abstract

The invention relates to a three-stage energy-dissipating ship box nested in a lock chamber of a ship lock and a ship lock-passing method, belonging to the technical field of design of hydraulic structures and water delivery systems of navigable ship locks. The ship body, the bollards arranged on the ship body, the buoys arranged on both sides of the ship body, and the upper and lower end doors respectively arranged at both ends of the ship body; the two sides of the ship body There are a number of energy dissipation holes on the side wall for eliminating the water flow energy entering the lock chamber during the water delivery process; the two sides of the ship box body are provided with transverse holes for consuming the transverse dynamic water load acting on the ship box body and the transverse impact force of the ship. Limiting tires; both sides of the ship body are equipped with longitudinal limiting tires for consuming the longitudinal dynamic water load acting on the ship body and the longitudinal impact force of the ship. This application designs a three-stage energy dissipation mechanism, so that the ship compartment has a significant energy dissipation effect, improves the berthing conditions of the ship, and simplifies the structure of the ship lock water delivery system.

Description

technical field [0001] The invention belongs to the technical field of design of navigable ship lock hydraulic structures and water delivery systems, and relates to a three-stage energy-dissipating ship box nested in a ship lock chamber and a method for ships passing through the lock. Background technique [0002] With the rapid development of inland shipping, my country has built a number of high-head and large-scale ship lock projects, such as the Three Gorges of the Yangtze River. The five-stage ship lock design has a total head of 113m and a scale of 280m×34m×5m (length×width×minimum water depth on the sill, The same below), Minjiang Jianwei ship lock design head 19m, scale 220m×34m×4.5m, etc. [0003] However, with the increase of the water head and plane scale of the ship lock, the energy entering the lock chamber per unit time during the water transfer process increases exponentially, limited by the initial water depth of the ship lock and the water transfer time, the ...

Problems solved by technology

[0005] There are bound to be some disadvantages in adopting a complex water delivery system, such as: (1) the project cost and construction difficulty are constantly rising; (2) the resistance coefficient of the water delivery system is greatly increased, and at the same time, the opening and closing time of the valve is required to be extended, resulting in water delivery time If it is too long, it will seriously affect the passing capacity of the lock
