Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing.

[0042] Such as Figure 1-6 As shown, the movable energy-storage scouring device of the present invention is mainly composed of a water-retaining main unit, a bank slope water-retaining unit and a diversion groove. The main water-retaining unit refers to the water-retaining unit within the toe of the river slope, which is composed of units with the same function and different widths. The units with different widths can be combined according to requirements to form structures with different widths to adapt to For rivers with different widths, the main water-retaining unit controls the water-passing section and provides the buoyancy of the lifting device; the bank-retaining unit refers to the water-retaining unit from the toe to the shoulder of the river slope. The bank slope water retaining unit is suitable for bank slopes with different slopes, provides the buoyancy of ...

Abstract

The invention provides a movable energy storage sludge flushing device which is composed of a main water blocking unit, a bank slope water blocking unit and a diversion trench. The main water blocking unit is a water blocking unit within slope toes of a river channel and is formed by units with the same function and different widths, and all the units with different widths are combined as required to form structures of different widths so as to adapt to river channels of different widths. The bank slope water blocking unit is a water blocking unit from the slope toes to slope shoulders of the river channel, is suitable for bank slopes of different gradients and is used for providing buoyancy for supporting a device and blocking water of slopes. The diversion trench is used for separating flushing water flow and downstream river water to reduce energy losses along the channel. The invention further discloses a movable energy storage sludge flushing method. The movable energy storage sludge flushing device and method can effectively overcome defects in an existing sludge flushing method, the energy of storage water flow is used for flushing sludge, manpower and material resources are saved, and the sludge removing effect is good.

Description

technical field [0001] The invention relates to the technical field of river dredging, in particular to a movable 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. With the rapid economic development in plain areas, the problem of river siltation and pollution is becoming more and more serious. The siltation reduces the regulation and storage capacity of the river network and the section of the flood discharge channel, and th...
