The invention relates to a solidification method for forming hard shell layer rapidly on storage
yard, used in the rapid foundation treatment to the large amount of dredged mud storage
yard generated in hydraulic and
water environment treatment, and harbor and navigation channel construction. The invention comprises the following steps: a) mixing the mud and solidification material and stirring, and laying the mixture on the surface of the storage
yard; b) after the solidified mud is hardened, the constructor walks onto the hard shell layer carrying machines to lay the mixture forwards on until the whole storage yard is completed. Aiming to the problems that: the hydraulic filled mud with
high water content has a low strength, the constructors and machines can not enter, and the foundation reinforcing treatment has to be postponed for a long time, the invention provides the method capable of forming an artificial hard shell layer on the surface of hydraulic filled mud in a short time after hydraulic filling; provides a manmade construction platform for constructors and machines, thereby shortens the total storage yard foundation
treatment time.
