Description

technical field [0001] The invention belongs to the technical field of environmental geotechnical engineering, and relates to a rapid dehydration and solidification device for river silt, in particular to a device for obtaining silt soil with no large particle impurities and high solidification strength by using the fluidity of high water content silt soil through a screening system Curing device. Background technique [0002] Silt is a flocculent and honeycomb structure formed by the deposition of fine particles such as clay minerals under the action of intergranular electrostatic force and molecular gravity in slow flowing water environments such as ocean or lake areas. Sludge is a kind of engineering waste soil with high water content. Its water content is mostly 1.2 to 2.0 times of the liquid limit water content. It is in a flowing state and has almost no strength, so it cannot be used directly for engineering. [0003] my country has a vast land and abundant resources,...

Problems solved by technology

The curing agent treatment method can not only consume a large amount of dredged silt, but also solve the difficulty of engineering soil shortage in some areas. It has the advantages of large processing capacity and short processing time. It needs to invest a lot of manpower, material resources or large equipment, otherwise it will lead to a large amount of additional consumption of curing agent or uneven mixing, resulting in unstable strength of the treated silt soil
