Problems solved by technology

[0003] At present, dredging methods commonly used in dredging projects include cutter suction dredging of cutter suction dredgers, open dredging of chain bucket ships and grab ships, etc. In the actual dredging process of these dredging methods, there are generally suctioned dredging The concentration of dredging mud is low, resulting in a large amount of dredged residual water treatment

Abstract

The invention provides a dredging structure and method for silt in the nearshore area of a sea. The dredging structure comprises a dredging boat, a dredging mechanism, a water pump and a dewatering mechanism, wherein the dredging mechanism is fixed to the side wall of the dredging boat, the water pump and the dewatering mechanism are arranged on the dredging boat, and after being connected with the dredging mechanism, the water pump delivers mud-containing seawater drawn by the dredging mechanism into the dewatering mechanism for dewatering. By means of the dredging structure and method, siltin the nearshore area can be rapidly removed, the concentration of sucked mud is increased, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a dredging structure for silt, in particular to a dredging structure and method for marine nearshore silt. Background technique [0002] Dredged silt is dredged soil with high moisture content produced during the dredging of ports, waterways, lakes and oceans. With the rapid growth of my country's ports, waterways, marine and coastal engineering construction and maintenance projects, marine dredging silt is increasing rapidly. The total amount of dredging silt produced in the Pearl River Delta region of my country alone has reached hundreds of millions of cubic meters. [0003] At present, the dredging methods commonly used in dredging projects include cutter suction dredging of cutter suction dredgers, open dredging of chain bucket ships and grab ships, etc. In the actual dredging process of these dredging methods, generally there is suction The concentration of dredging mud is low, resulting in a large amount of dredged resi...
