Abstract

The invention relates to an energy-saving combined double-body ship for cleaning river water bottom sludge and a corresponding river silt removing method. In order to fill up the blank in the prior art, the energy-saving combined double-body ship for cleaning the river water bottom sludge comprises N rake assemblies, a main hull and an auxiliary hull, wherein each rake assembly comprises a cutterhead, a connecting plate and a tail rake, the middle section and the rear part of the connecting plate are hinged to a front control rod and a rear control rod respectively, the upper parts of the front control rod and the rear control rod are bound and fixed to handrails on the side wall of the outer side of the auxiliary hull through binding ropes, a pull rope is tied on the front part of the cutter head of each rake assembly, and the other end of the pull rope is tied on the inner wall of the main hull, wherein N is a positive integer, N is greater than or equal to 3 and less than or equalto 100, the length of the control rod is larger than twice of the depth of the river water to be cleaned, the length of the pull rope should be around the bottom of the auxiliary hull, and the rake assembly can still be moved to the auxiliary hull. The method has the advantages of being low in energy consumption and low in cost, is suitable for serious deposit rivers, and is especially suitable for silt removing of different river segments in the middle and lower streams of the Yellow River.

Description

technical field [0001] The invention relates to an energy-saving combined catamaran for cleaning mud at the bottom of rivers and a corresponding river dredging method. Background technique [0002] Rivers are important freshwater water systems in inland areas. Various small surface runoffs such as creeks flow into rivers, which further flow to the sea. When a river accepts various streams, it inevitably accepts the sediment carried by the streams at the same time. [0003] The Yellow River is the mother river in the north of my country. When the Yellow River flows through the Loess Plateau of my country, the sediment carried by the ground runoff on the Loess Plateau enters the Yellow River. true portrayal. The silt in the Yellow River goes eastward and deposits all the way. Over time, these silts are deposited on the bottom of the river, gradually raising the river bed, forcing people to continuously build higher river embankments, and even forming above-ground hanging riv...
