Embodiment approach

[0013] Utilize the method of the present invention to process the silt pit produced by the Shouqin reclamation and land reclamation project in Qinhuangdao Economic and Technological Development Zone. It is 100 meters by 100 meters and the depth is about 10 meters. The silt pit in the flow-plastic state has extremely low bearing capacity, throwing stones and sinking quickly, and the ground endurance is ≤0.5t / m 2 The specific implementation method is as follows:

[0014] (1), choose the discarded calcium-containing fly ash of the power plant, the particle diameter of the calcium-containing fly ash is between 0.2-8mm, and the calcium oxide weight percentage in the calcium-containing fly ash is 20%. The weight percent composition of calcium is 0.3%;

[0015] (2) According to the endurance requirements of the designed ground base, use a backhoe to mix calcium-containing fly ash with water glass at a volume ratio of 40:1, and then stir and mix with sea silt at a volume ratio of 1:...

Abstract

The invention discloses a modification processing method by utilizing powdered coal clinker to carry out a soft base soil body; after the waste calcium-containing powdered coal clinker and water glass are mixed according to volume ratio of 35:1-45:1 by an excavator, and then the mixture is mixed with the soft base soil body by stirring according to the 1:1-1:2 volume ratio, the mixed soil body is backfilled, and the modified soil body is solidified by grinding and standing; the mixed soil body stands still for 60-84 hours and then is solidified; the soft base soil body including sludge in sea, sludge in lakes or sludge in rivers, the particle size of the calcium-containing powdered coal clinker is 0.2-8mm. the calcium oxide weight percentage content in the calcium-containing powdered coal clinker is 15-35 percent, and the flowing calcium weight percentage content is 0.2-0.4 percent; by adopting the processing method, the construction cost is low, the construction period is short, the problem of the waste residue treatment is not only solved, but also the construction cost of the soft foundation treatment in the engineering is reduced, circulating economic utilization is realized and the economic benefit is remarkable.

Description

technical field [0001] The invention relates to a fly ash utilization method, in particular to a method for modifying soft foundation soil by using fly ash slag. Background technique [0002] my country's power plants produce a large amount of fly ash every year, how to make better use of fly ash has become a very important environmental protection issue. Making better use of the characteristics of fly ash to solve problems in actual production and life can not only achieve the purpose of facilitating the treatment of fly ash, but also serve the production and life of human beings. [0003] The silt in the sea contains salt and alkali, which will cause harm to the environment for a long time. Most of the silt treatment methods in the prior art are drainage consolidation method, replacement and filling method, etc. The soil structure produced by such treatment technology has construction problems. The disadvantages of long period, complicated construction, high cost, and lar...
