Diversion dike and its diversion methods

Abstract

The present invention provides a diversion and separation dike and its diversion method, including several support groups, any two adjacent support groups are connected with inserting boards, and the support groups include a first connecting pier and a second As for the connecting piers, one inserting plate is arranged between every two adjacent supporting groups. The beneficial effect of the present invention is to improve the navigable water flow conditions at the gate area of ​​the approach channel of the ship lock, and effectively avoid adverse flow states such as bubbles and turbulence. ; This device uses the method of blocking and dredging the water flow to weaken the oblique water flow in the gate area of ​​the ship lock to ensure the safe navigation of the ship.

Description

technical field [0001] The invention relates to the field of diversion equipment in the gate area of ​​a ship lock, in particular to a diversion dike and a diversion method thereof. Background technique [0002] The gate area of ​​the approach channel of the ship lock is the throat of the ship entering and leaving the approach channel. It is the junction area between the moving water of the main channel and the still water of the approach channel. The water flow shrinks or expands here. The water body in the main channel interacts with the still water in the approach channel, and the water flow undergoes plane bending deformation , forming an oblique current, affecting the safe navigation of ships. Therefore, it is of great practical significance to improve the water flow conditions at the entrance area of ​​the approach channel of the ship lock. Scholars at home and abroad have studied a variety of improvement measures, such as adjusting the form of the diversion embankmen...

AI Technical Summary

Problems solved by technology

[0003] However, for rivers in mountainous areas, due to the large head difference between the upstream and downstream of the hub, the hydrodynamic environment at the entrance area of ​​the approach channel downstream of the ship lock is complex, and the flow velocity and oblique flow intensity in the entrance area are relatively high. Bad flow patterns such as whirlpools and bubbling water are formed in the entrance area, which seriously affects the safe navigation of ships. The current barrier dike only uses the form of a barrier to prevent oblique water flow. However, as a fluid, it will bypass the divider. Form an upward surge of water flow, which causes the instability of the ship when the ship enters or exits the gate area of ​​the approach channel of the lock, and is prone to accidents, so the form of blocking alone is not enough to meet the actual needs
