Underwater water taking system, ship lock water inlet system with underwater water taking system and construction method

Abstract

The invention provides an underwater water taking system, a ship lock water inlet system with the underwater water taking system and a construction method. The underwater water taking system comprises a water inlet system and a water conveying system; the water inlet system and the water conveying system are connected and arranged in an approach channel; the water inlet system comprises a water inlet box culvert; a box culvert pit is formed in the approach channel; the water inlet box culvert is arranged in the box culvert pit; the water conveying system comprises a water conveying box culvert; the water conveying box culvert is buried at the bottom of the approach channel and connected with the water inlet box culvert to convey water flow entering from the water inlet box culvert; and the burying depth of the water conveying box culvert is 1 m. According to the underwater water taking system, the ship lock water inlet system with the underwater water taking system and the construction method, direct water taking from the approach channel is avoided, the wave height and the flow speed in the approach channel can be reduced by about 50% when a ship lock is used for water filling, the water flow condition in the approach channel is improved, meanwhile, the construction process is dry land construction, and the construction difficulty can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of navigable water conservancy buildings, and in particular relates to an underwater water intake system, a ship lock water intake system with the system and a construction method. Background technique [0002] The approach channel is an important part of the ship lock. Its function is to guide ships to enter and exit the lock chamber quickly and safely. In order to ensure the safe docking of ships and the safe driving of ships passing the lock, there must be sufficient water depth and suitable water flow conditions in the approach channel. The approach channel is a restrictive channel and is close to the ship lock. Its water flow conditions are complicated by the irrigation and discharge of the ship lock. When the ship lock is filled with water, an unsteady flow will be generated in the approach channel, which will cause fluctuations in the water surface and changes in flow velocity and flow state, which wil...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the water flow velocity of the narrow and long approach channel upstream of the lock exceeds the standard and the fluctuation is large when the large-scale ship lock is filled with water, and an underwater water intake system, a ship lock water intake system with the system and a construction method are designed.
