Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dredging equipment, and specifically relates to a dredging equipment for river regulation. BACKGROUND

[0002] As an important water ecological system, the sediment accumulation of a river has been a key challenge in environmental protection and water resource management, and the sediment accumulation not only affects the self-purification ability of the water body, but also seriously affects the habitat and living conditions of aquatic organisms, in addition, the sediment accumulation can also cause water flow obstruction, flood disasters and other problems, therefore, it is particularly important to regularly carry out dredging work on the river.

[0003] At present, for the river sediment dredging, two methods of dry dredging and wet dredging are mainly used. Among them, although the dry dredging is widely used in the early stage, it has been gradually eliminated, the main reason is that it needs to be partially interrupted, which can seriously affect the river ecological environment and the surrounding ecology, and the realization of the interrupted construction brings great difficulties to the dredging work, and also limits the efficiency and implementation range of the dredging work.
