Double-gate regulation and control system with functions of water diversion, moisture absorption and silt flushing and regulation and control method of double-gate regulation and control system

Abstract

The invention discloses a double-gate regulation and control system with functions of water diversion, tide receiving and silt flushing and a regulation and control method of the double-gate regulation and control system. The double-gate regulation and control system comprises a spur dike, a water diversion head hub, a tide gate, a rectification weir and a tide receiving gate which are sequentially arranged from the upstream to the downstream of the system. The spur dike plays a role in guiding river sediment and relieving siltation; the water diversion head hub is used for draining clear water and muddy water; the tide gate is used for retaining flood and preventing salt tide from upstream pollution to an upstream water body; the rectifying weir can effectively narrow a river channel, increase the flow velocity of water flow in an area and enhance the sand carrying capacity of the water flow; the tide receiving gates and the tide blocking gates are arranged in a staggered mode, the total clear width of the gates is smaller than that of the tide blocking gates, the clear width of the river channel is further shortened, and the water restraining and sand tapping effect is improved. The tide gate is used for achieving the water diversion irrigation function, the tide weather mode and the double-gate opening and closing system are combined to achieve the functions of high tide receiving and low tide silt flushing, the tide blocking and flood discharging capacity of the system is effectively enhanced, and certain economic benefits are achieved.

Description

technical field [0001] The invention relates to a silt removal system and a silt removal method for a coastal tide gate, in particular to a double gate control system and a control method with functions of diverting water and absorbing tide and scouring and silting. Background technique [0002] Tidal gates play an important role in preventing moisture and typhoon, improving flood and waterlogging capacity, preventing land salinization, and alleviating the contradiction between supply and demand of water resources. However, the establishment of tidal gates changed the dynamic conditions of the river coast and the energy balance between runoff and tidal currents, resulting in serious sedimentation problems in the river channels under the gates, which significantly reduced the flood discharge capacity of the river channels. [0003] At present, the main methods for controlling sedimentation under the tide gate are as follows: [0004] (1) Expand the water source, divert water...

AI Technical Summary

Problems solved by technology

However, tidal scouring and silting will inevitably lead to siltation of upstream rivers, and induce serious problems of salt tide upstream, resulting in salinization of upstream land
