Abstract

The invention discloses a water-proof and solidifying method for underwater silt, which isolates the silt from the upper water body and then solidifies; it also provides a curing device, including a stirring system, a water-proof system, a curing agent delivery system and a walking system; the water-proof system It is used to isolate the sludge from the upper water body, the stirring system is used to mix the isolated sludge with the curing agent, the curing agent delivery system is used to transport the curing agent into the sludge, and the walking system is used to drive the water barrier System moves. The invention solidifies directly under water without dredging; solidifies with water isolation, eliminates the problems of sludge diffusion and curing agent loss caused by stirring; and improves water quality without dredging.

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...
