Abstract

The invention relates to the technical field of waste mud muck treatment, and discloses a waste mud muck in-situ curing and mixing construction method which comprises the following construction steps: 1) leveling a construction road; a curing agent is stored in a storage bin, and the curing agent comprises, by mass, 25%-40% of Portland cement, 20%-30% of fly ash, 10%-20% of building gypsum, 1%-2% of an additive and 1%-5% of an early strength agent; 2) stirring the curing agent in an upper stirrer, and stirring the curing agent with water in a lower stirrer to form a mixture; (3) the stirrer is provided with a stirring shaft, the stirring shaft is connected with a rotating head, a containing cavity is formed in the rotating head, the rotating head is provided with a spray head, a hinge shaft is arranged in the containing cavity in a penetrating mode, the hinge shaft is hollow and rotationally connected with a conveying pipe, and the conveying pipe is connected to the lower stirrer; and the mixture is conveyed into the containing cavity of the rotating head through the conveying pipe and sprayed into the waste mud residue soil through the spraying head till the mixture and the waste mud residue soil are evenly stirred.

Description

technical field [0001] The patent of the present invention relates to the technical field of waste mud and dregs treatment, and specifically relates to a construction method for in-situ solidification and mixing of waste mud and dregs. Background technique [0002] In urban engineering construction, especially in projects using mud retaining technology, a large amount of waste mud slag will be formed. For waste mud and slag, solidification treatment is the most commonly used treatment method at present. [0003] At present, the basic principle of solidification treatment of waste mud slag is: add curing agent, such as cement, dry miscellaneous soil, etc. %-20% cement, and then, after the waste mud slag is dried and hardened, it is transported to the spoil yard. [0004] In the prior art, there is a disadvantage of high cost in using the above-mentioned solidification treatment of waste mud and dregs, and the treated waste mud and dregs are not recycled again, which not onl...
