Self-sliding energy storage scouring device and scouring method

Abstract

The invention discloses a self-slippage energy-storage sluicing device which consists of a water-retaining main unit and a bank slope water-retaining unit, wherein the water-retaining main unit is a water-retaining unit in a riverway side slope toe and consists of units which are same in function and different in width, and the units which are different in width are combined according to requirements to form structures different in width so as to adapt to basic requirements of riverways different in width; the bank slope water retaining unit is a water retaining unit positioned between the riverway side slope toe and a slope shoulder part and at the river bottom width variable part in the riverway side slope toe. The invention also discloses a sluicing method of a self-slippage energy-storage sluicing device. The self-slippage energy-storage sluicing device and the sluicing method can be used for effectively overcoming the defects in the existing sluicing method; self energy of accumulated water flow is utilized for sluicing; self mechanisms of the device are utilized for regulating the deadweight and controlling friction forces; the device can automatically slide towards downstream under the effect of an upstream horizontal water pressure and is capable of sluicing sludges at the river bottom while sliding towards the downstream, so that manpower and material resources are saved and the dredging effect is good.

Description

technical field [0001] The invention relates to the technical field of river channel dredging, in particular to a self-sliding energy storage scouring device and a scouring method. Background technique [0002] The plain river network has typical characteristics such as gentle river channels, small water surface gradient, low flow velocity, and variable flow direction. For example, the water surface gradient of the Hangzhou section of the Canal is about 1 / 80,000 to 1 / 150,000, and the flow velocity is only 0.1m / s Left and right, this hydrological feature makes the plain river network have the characteristics of weak water pollution dilution ability, poor regulation and storage capacity of the river network, and easy siltation. The siltation reduces the regulation and storage capacity of the river network and the section of the flood discharge channel, and the floods occur frequently in the rainy season; the water flow velocity decreases in the non-drainage season, the river's...
