A method for arranging approach channels with water diversion and diversion channels combined with a bottom-permeable navigation wall

Abstract

The invention relates to a method for arranging an approach channel combining water diversion and diversion channels with a bottom-permeable navigation wall, which belongs to the technical field of overall arrangement of navigable buildings. The approach channel of the water diversion channel combined with the bottom permeable navigation wall is arranged at the entrance of the upstream approach channel; the bottom permeable navigation wall is arranged along the direction of the channel between the approach channel and the main river, and the bottom permeable navigation wall is only provided with permeable holes at the bottom , the upper part is a solid structure; on the root platform of the navigation wall, that is, on the end platform of the bottom transparent navigation wall near the ship lock, a water diversion and diversion channel is set up; the water diversion and diversion channel must be arranged at a certain angle with the approach channel route, Connect the approach channel with the main channel; arrange gates on the diversion channel. The beneficial effects of the present invention are as follows: 1. No additional site space is occupied for the approach channel of the ship lock, and the amount of newly added engineering is small, which has obvious economical efficiency; 2. Significantly improves the navigable water flow conditions in the entrance area of ​​the approach channel with large flow and large curvature. .

Description

technical field [0001] The invention proposes a method for arranging an approach channel of a ship lock, in particular a method for arranging an approach channel in which a water diversion channel is combined with a bottom-permeable navigation wall, and belongs to the technical field of overall arrangement of navigable buildings. Background technique [0002] The upper and lower reaches of the lock are connected to the main river through the approach channel and the gate area, so the navigable water flow conditions in the gate area of ​​the approach channel directly affect the safety of ships passing through the lock, and it is the throat for ships (teams) to enter and exit the lock. [0003] In order to ensure the smooth and stable water flow in the approach channel, 5.6.4 of the "General Design Code for Ship Locks" requires that "the angle between the center line of the approach channel, the gate area and the connecting section and the main flow direction of the river or th...

AI Technical Summary

Problems solved by technology

[0007] 1. When the flow rate is high, the angle between the centerline of the channel and the main flow is greater than 25°, and the curved river channel cannot solve the problem of navigation of the ship lock through navigation walls, diversion piers, etc., which reduces the navigation guarantee rate of the ship lock project

[0008] 2. When the flow is low, the water surface at different positions in the river often has a lateral water head difference, and the water level at the mainstream is often slightly higher than the water level of the approach channel, and the resulting lateral flow has an adverse effect on the water flow in the approach channel
