Abstract

The invention discloses an underwater sludge waterproof solidification method. Sludge is isolated from an upper water body and then solidified. The invention further provides a solidification device.The solidification device comprises a stirring system, a waterproof system, a curing agent conveying system and a walking system, wherein the waterproof system is used for isolating sludge from theupper water body, the stirring system is used for mixing the isolated sludge with a curing agent, the curing agent conveying system is used for conveying the curing agent into the sludge, and the walking system is used for driving the waterproof system to move. Underwater direct solidification is achieved, and desilting is not needed; the problems of sludge diffusion and curing agent loss causedby stirring are eliminated through waterproof solidification, and the water quality can be improved without desilting.

Description

technical field [0001] The invention relates to a water-proof and solidifying method for underwater silt and a solidifying device used therefor, belonging to the field of water conservancy engineering facilities. Background technique [0002] In order to improve the water quality of rivers and lakes and ensure the normal navigation and flood discharge capacity of rivers, countries all over the world are carrying out large-scale dredging projects. However, the amount of silt to be cleared is huge, and it is often necessary to build a silt yard to store or dump it into the ocean. Among them, the silt yard generally covers an area of ​​more than 100 mu, and involves demolition, agriculture, fishery compensation, and land pollution, which brings great difficulties to the project. In addition, dumping into the ocean will also cause irreparable damage to the marine environment. Therefore, land occupation, environmental pollution and cost pressure caused by sludge disposal are be...
