Description

technical field [0001] The invention belongs to the field of dredging and reclamation areas with thick silt bottom, and in particular relates to an energy dissipation device, an energy dissipation system and a construction method for anti-crowding and silt laying construction in a dredging and filling area with thick silt bottom. Background technique [0002] As there are more and more land reclamation projects in coastal areas, it is necessary to reclamation from the sea to form land areas, build factories, port yards, roads, and real estate development projects. Most of the dredged filling soil is sandy soil, so that after the sand blowing pipeline is removed, machinery and equipment can be put on land for onshore construction soon. [0003] In traditional reclamation projects, the excavation system and pumping system of cutter suction dredgers or trailing suction dredgers are mainly used to transport the sediment several kilometers away to the designated reclamation area ...
