Problems solved by technology

[0003] The dredger filling soil in the coastal area is basically silt and silty soft soil, which has the characteristics of high water content, high permeability, low strength, and the inability of personnel and machinery to directly enter the site, which brings great resistance to the development and construction of the coastal area
[0004] Although there are currently some curing agents on the market that have a certain effect on the curing of soft soil with low moisture content, for marine sludge with high water content, the treatment effect is not good and the cost is high

Abstract

The invention provides a tidal flat soft soil reinforcing agent and a preparation method thereof, belonging to the field of soft soil treatment. The tidal flat soft soil reinforcement agent includes a main curing agent and a curing auxiliary agent used together. The main curing agent includes by weight: 40-60 parts of geopolymer slurry, 5-10 parts of fly ash particles, polyvinyl alcohol 1 to 3 parts, 2 to 4 parts of ethyl cellulose, 8 to 12 parts of modified lignosulfonate, 4 to 7 parts of crosslinking agent; the curing aid includes 12 to 18 parts of epoxy olefin in parts by weight , 4-6 parts of diethylenetriamine, 7-9 parts of styrene-butadiene block copolymer, 7-10 parts of potassium sodium tartrate. This tidal flat soft soil reinforcement agent has a strong reinforcement performance for tidal flat soft soil with high water content. The tidal flat soft soil cured by this reinforcement agent has high strength, good water stability, good compressive strength and durability .

Description

[0001]The invention relates to the field of soft soil treatment, in particular to a tidal flat soft soil strengthening agent and a preparation method thereof.Background technique[0002]In recent years, with the rapid economic and social development in coastal areas, the contradiction between the supply and demand of construction land has become increasingly prominent. The development and utilization of abundant tidal flat resources in coastal areas has become the main way to solve the shortage of land resources in these areas. Land reclamation is currently the main method of land development along beaches.[0003]The dredger fill in coastal areas is basically silt and silty soft soil, which has the characteristics of high water content, permeability, low strength, and the inability of personnel and machinery to directly enter the site, which has brought greater resistance to the development and construction of coastal areas.[0004]Although there are currently some curing agents on the m...
