Method for treating pickled soft base through industrial residues

Abstract

The invention relates to a method for treating a pickled soft base through industrial residues. The method has the characteristics of being good in treating effect and capable of achieving waste recovery and protecting the environment. According to the technical scheme, the method for treating the pickled soft base through the industrial residues comprises the following steps that (1), staking out in survey is conducted on the levelled pickled soft base to determine stake positions; and (2) nail-shaped bidirectional stirring powder pile spraying construction is conducted, powder during the construction is composed of waste tire rubber powder and an industrial residue curing agent, the components are controlled, by mass, to be 67-73 parts of pickled soil, 17-23 parts of the waste tire rubber powder and 7-13 parts of the industrial residue composite curing agent; the industrial residue composite curing agent is composed of, by mass, 57-63 parts of acetylene sludge, 27-33 parts of flyash and 7-13 parts of excitants; and the excitant is MgO or / and Cao, and maintenance is conducted for seven days.

Description

Technical field [0001] The invention belongs to the treatment field of coastal saline soft soil foundation, and particularly relates to the treatment and reinforcement treatment construction of the saline soft foundation disease of highways and urban roads in coastal areas. Background technique [0002] With the implementation of my country's marine economic development strategy, construction tasks such as port dredging roads, tidal flat reclamation, and land reclamation have become increasingly onerous. The coastal foundation has been immersed in seawater for a long time and has the typical characteristics of saline soft soil. It not only has high water content, large void ratio, high compressibility, low shear strength, but also has salt swelling, swelling, corrosive and strong moisture absorption properties. At present, coastal saline soft foundations are mainly treated by drainage board combined with preloading, lime compaction piles, high-pressure jet grouting piles and oth...

AI Technical Summary

Problems solved by technology

At present, the coastal saline soft foundation is mainly treated by drainage board combined with surcharge preloading, lime compaction pile, high-pressure rotary grouting pile and other methods. Since the characteristics of saline soft soil foundation are not considered, the treatment effect is not very satisfactory.

[0003] On the other hand, industrial wastes such as calcium carbide slag, phosphogypsum, blast furnace slag, and alkali slag are produced in large quantities, which not only take up a lot of space, but also pollute the environment, destroy the ecology, and restrict the sustainable development of society.
