Abstract
The invention relates to a curing agent for treating a deep soft foundation soil layer and a preparation method thereof. The curing agent consists of metal oxides with activity of Al2O3, Fe2O3, CaO and MgO, nonmetal oxides with activity of SiO2 and SO3, and an acyclic sulfonate water-reducer. The preparation method for the curing agent comprises the following steps of: drying the metal oxides and the nonmetal oxides in a dryer, and heating at the temperature of between 750 and 850DEG C for 3 to 4 hours; grinding into granules that the residue of a 80 mu m square sifter is not more than 4.0 percent by using a ball mill; and adding the acyclic sulfonate water-reducer and uniformly stirring to obtain the curing agent for treating the deep soft foundation soil layer. The curing agent can make the unconfined compressive strength, deformation, permeability, liquefaction resistance and other properties of the treated soft foundation soil body obviously improved.
Description
Technical field
The present invention relates to a kind of in various engineerings for the treatment of solidifying agent of deep soft foundation soil layer and preparation method thereof.
Background technology
Highway, especially motorway are often because the requirement of circuit need be at deep soft foundation area Filling High Embankment.And build embankment on these soft bases in, if soft base is not handled well, just might when construction, unstability occur or excessive foundation settlement occurs behind completion of works.So developed country in the money generally selects viaduct to construct to avoid the massive losses that brings of rebuilding that after this may occur for problems.China coast, except part location, Shandong, most shoreline is muddy coast.Plain and interior plain near coastal great river, the river mouth, great river mostly are river facies, marine facies or lagoonal facies settled layer, mostly belong to saturated normal consolidation clay.The classification of soil mostly is the soil layers such as mud, silt clay, Muddy Bottoms mild clay.These weak soils generally have the characteristics such as high-moisture, open grain, low density, low strength, high-compressibility, low permeability.Do engineering at this type of ground, all can bring disadvantageous effect to construction quality if treatment of soft foundation is bad or operational procedure is improper, even cause project failure.This type of quality story example happens occasionally, secondary treatment costly.
The main punishment technology of high embankment comprises consolidation, berm with superloading, bed course and shallow-layer processing, geosynthetics, composite foundation etc. on the deep soft foundation.Foundation consolidating technology has preloading, Vacuum-loading Pre-pressing Method, compound foundation method etc.Deep layer agitation of cement method starts from the U.S., and introduce Japan the 1950's, and develops the deep-layer stirring machinery of all size.Thereafter deep mixing method is used widely in flabbiness ground strengthened.China also begins to carry out shop experiment and the mechanical development work of deep mixing method in the seventies, be widely used in the engineering projects such as foundation stabilization, side slope protection, antiseepage now.Deep layer agitation of cement method is to utilize the materials such as cement, lime as solidifying agent, by special deep-layer stirring machinery, on the spot weak soil and solidifying agent are forced to mix and stir in the ground depths, utilize the series of physical-chemical reaction that produces between solidifying agent and the weak soil, weak soil is hardened into have high-quality ground or the underground earth-retaining structure of globality, water stability and some strength.Deep layer agitation of cement method is suitable for processing the soft clay grounds such as mud, mucky soil, clay, silty clay, silt, slope retaining, foundation ditch antiseepage etc.
How to develop new more efficiently solidifying agent for the treatment of deep soft foundation soil layer be the insider everybody make great efforts for it the problem explored.
Summary of the invention
Purpose of the present invention provides a kind of solidifying agent of processing deep soft foundation soil layer and preparation method thereof.This solidifying agent can make the soft subgrade soil body after the processing all have clear improvement at aspects such as unconfined compression strength, deformability, Penetration Signature and anti-liquefying powers.
