Description
Technical field:
The present invention relates to a kind of solidifying agent, particularly a kind of highway is with the method for solidifying agent and curing sub-surface thereof.
Background technology:
In the road construction process, need to use such as pavement materials such as gravel, soil, stone, cement, pitches in a large number, wherein the consumption with basic unit and subbase course material is big especially.How the plains region utilizes near the silt resource of enriching the road construction project as road engineering material; Satisfy the specification of quality of different grades road engineering to base material; Save the construction project cost; Making up the green traffic environment, is great technology, the economic problems that field of traffic need solve.Silt is very poor as the engineering property of road basement material, and constructional difficulties is difficult to guarantee the road engineering quality.It is the effective measure of improving its engineering property that silt is cured processing, and wherein selecting cement, lime, soil-solidified-agent to be cured is technological method comparatively commonly used.Cement solidification: (1) cement to the high clay of plasticity index, to split soil, organophilic clay and saline soil solidification effect very undesirable, even do not have solidification.(2) the solidified cement body drying shrinkage is bigger, easy to crack.(3) cement just, final setting time can't adjust, and influences construction quality.Lime solidifies: the cured body intensity that (1) lime and soil form forms slowly, often influences construction speed.(2) intensity of lime cured body is directly proportional with the volume of lime within the specific limits, goes beyond the scope if improve volume, and then the intensity of cured body descends on the contrary.Therefore, for the higher engineering of cured body requirement of strength, it is powerless that lime seems.(3) drying shrinkage big, easy to crack, be prone to softening, water stability is poor.Therefore, the lime solidified earth is under an embargo in highway system as the basic unit of high class pavement, and can only handle as subbase.Two grey compounds solidify: in recent years, lime-flyash is widely used in the stabilizing treatment of roadbase, subbase by highway in China department.But in use find lime-flyash morning epistasis and water stability poor, directly influence construction speed and quality.Be difficult to solve silt based on cement, lime and two grey compounds and solidify the problem that exists; In recent years; A lot of entity and individual are studied the soil-solidified-agent with property, have successively obtained a series of achievements in research, and disclose some technology: used carbide slag; The solidifying agent that granulated blast-furnace slag, chemical activator are mixed and made into; A kind of pair of component solidifying agent of building the road, the solid curing agent composition is: silicon-dioxide, aluminium sesquioxide, quicklime, Natural manganese dioxide, sulphur trioxide, sulphate activation agent 1-5%; The composition of liquid curing-agent is: caustic soda, sulfuric acid, phenol, colophonium powder.Disclose a kind of soil quality stabilizing and curing agent, it is by calcium, and inorganic materials such as magnesium iron are main body, is equipped with the material that proper catalyst is formed.Patent 98113594.3 discloses a kind of working method of soil-solidified-agent, it is characterized in that with slag or slag compsn be body material, is equipped with an amount of alkali-activator, cement and tensio-active agent combined grinding to Blain specific surface 400-900m
2/ kg is made.Comprehensive existing document is not difficult to find out, solidifies, does not see bibliographical information as yet without the method for cement and alkali-activator production solidifying agent to silt specially.
Summary of the invention:
The purpose of this invention is to provide a kind of effective highway of silt that solidifies with solidifying agent and working method thereof.Highway of the present invention is that a kind of highway is used solidifying agent, it is characterized in that with the technical scheme of solidifying agent: the composition of forming solidifying agent is by weight: blast furnace granulated slag 10-30 part, lime 20-40 part, desulfurated plaster 5-15 part, red mud 15-65 part.Highway of the present invention with the working method of solidifying agent is; A kind of highway with claim 1 is characterized in that with the method that solidifying agent solidifies sub-surface following steps are arranged: (1) with highway with solidifying agent 4-35 weight part, silt 65-96 weight part and water 10-25 weight part mixing and stirring after, (2) pave on roadbed; Paving thickness 360-400mm; Naturally place after 2 hours (3) roller-compaction, molding thickness 160-200mm; Behind the moisture-keeping maintaining, can on this sub-surface, carry out the making surface layer after the moulding.The present invention and prior art relatively have used solidifying agent and do not contain cement and alkali-activator and the remarkable advantage good to the solidification effect of silt.
