Abstract

The invention discloses a port aeration type sludge clearing method. The port aeration type sludge clearing method is characterized in that a port comprises a port main body, wherein a sludge storage slot is formed in the bottom of the side edge of the port main body; a plurality of gas-blowing pipelines and a plurality of sludge pumping pipelines are arranged in the port main body in a penetration mode; one end of each of the gas-blowing pipelines and the sludge pumping pipeline extends to a position above the port main body, and the other end of each of the gas-blowing pipelines and the sludge pumping pipeline communicates with the bottom-end plane of the sludge storage slot. Compared with the prior art, the port aeration type sludge clearing method has the advantages that: firstly, the cost is low and a great deal of engineering construction is not required; secondly, compared with the prior art which needs various process and has complex construction, the port aeration type sludge clearing method is simple in process and does not have very high construction requirements; and thirdly, the treatment effect is good, the problem that the sludge is blown away in the prior art is avoided, the sludge is directly sealed and not blown away in a gas blowing process while surrounded in a fixed area, and the purpose of completely clearing the sludge is achieved.

Description

technical field [0001] The invention belongs to the technical field of port construction engineering, and in particular relates to a port aeration type dredging structure and a dredging method thereof. Background technique [0002] During the operation of the port, a large amount of silt will be deposited on the edge of the port with the passage of time. To clean up the silt, dredgers and suction boats are usually used to remove the silt, but neither of them can remove the silt. clean. [0003] For example, the public number is CN103806484A (Announcement date is May 21, 2014) The Chinese invention patent has disclosed: Construction method of air lifting underwater dredging , the steps are as follows: (a) silt survey and classification: the silt in the dredging area is surveyed, at first adopting the artificial diving method of divers to survey, and the silt in the area is classified and recorded, and the record content includes: silt amount, Silt type, sediment particle ...
