Bay internal tide automatic flow dredging and automatic flow sand washing and dredging technology system

Abstract

Disclosed is a bay internal tide automatic flow dredging and automatic flow sand washing and dredging technology system. The system comprises a body dam with an upper gate and a lower gate, an outer drainage dam and an inner drainage dam. The horizontal plane difference caused by flood tide and falling tide inside and outside the body dam drives seawater to form organized flow under the guidance of the inner and outer drainage dams, and the problem of internal bay silt storage is solved, hardened sludge can be stirred on the basis of the combined effect of a sand washing ship, pure sludge mud accounting for a small amount of sludge can be washed away by adjusting the flow through the gates of the body dam and seawater washing in the guiding direction of the drainage dams, sea sand accounting for a large amount of the sludge is washed out through the sand washing ship is adopted as a building material, the amount of sludge discharged into ocean is decreased, and economic benefits are increased. The technology can be widely applied to travel and tidal power generation bay dredging projects.

Description

technical field [0001] The invention relates to a dam. The arrangement of the dam and the setting of gates can permanently and economically solve the problem of mud deposition in bays used for tidal power generation and tourism, and belongs to the technical field of water conservancy engineering. Background technique [0002] With the rapid consumption and shortage of non-renewable resources such as oil and coal, countries are stepping up the development of solar energy, wind power and tidal power generation projects. At this stage, my country has also given policy support to the development of these energy sources, and invested a lot of manpower and material resources. Therefore, tidal power generation is a green, environmentally friendly and permanent project that stores seawater in the bay in the form of potential energy during high tide, and then releases seawater at low tide to drive the turbine to rotate by using the difference between high and low tide levels to drive...

AI Technical Summary

Problems solved by technology

Due to the special geographical features of our country, these bays are easily filled with silt, especially when dams are built at the mouth of the bay where rivers flow in, which reduces the speed and shock of seawater backflow, increases the speed of silt deposition in the bay, and reduces the capacity of the bay. and the deterioration of the tourist environment

[0003] For land-based land and crop fields, marine silt is a heavy pollutant containing salt and alkali, and it is difficult to find a place to store it on land with conventional dredging; Earthwork, garbage, silt and other solid substances are scattered in the sea, so the accumulation and treatment of silt in the bay is a very difficult problem
