Flow diversion and isolation dyke and flow diversion method thereof

Abstract

The invention provides a flow diversion and isolation dyke and a flow diversion method thereof. The flow diversion and isolation dyke comprises a plurality of supporting sets. An insert plate is connected to the position between every two adjacent supporting sets. Each supporting set comprises a first connection pier and a second connection pier. One insert plate is arranged between every two adjacent supporting sets. The flow diversion and isolation dyke has the beneficial effects that the navigation flow condition of an entrance area of an approach channel of a ship lock is improved, and bad flow states of boil-eddy and turbulent flow are effectively avoided; the insert plates are divided to be straight insert plates and curve insert plates, in this way, construction can be conducted according to different actual situations; the flow blocking and guiding modes are adopted to weaken oblique flow at the entrance area of the ship lock so as to ensure safe navigation of a ship; the insert plates are inserted to the connection piers and can be replaced conveniently.

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
