Abstract
The invention relates to a soil body reinforced constructional material which can improve technical properties of soil and is used for solidifying multiple kinds of soil in civil engineering, in particular to a powdery soil solidifying agent for solidifying quasi-base courses and subbase courses in the solidification, pavement and foundational engineering on soft groundwork and the construction work on seabed groundwork. The powdery soil solidifying agent for solidifying the quasi-base courses and the subbase courses comprises the following components in part by weight: 27 to 42 parts of potassium chloride, 33 to 51 parts of sodium chloride, 30 to 48 parts of magnesium chloride, 3 to 12 parts of sodium sulfide, 15 to 27 parts of calcium chloride, and 1 to 8 parts of trimeric sodium phosphate. The powdery soil solidifying agent for solidifying the quasi-base courses and the subbase courses is suitable for the reinforcing solidification of surface soil bodies and deep soil bodies under various soil conditions, strengthens the strength, durability and economy of construction foundations, effectively solves the problems of sedimentation, breaking, slurry pouring and protuberating of road surfaces, which often appear in the conventional construction, prolongs the service life of roads, and reduces the costs for maintaining the roads.
Description
Technical field
The present invention relates to a kind ofly to improve the soil technology performance, in order to the soil stabilization material of construction of the civil engineering work of solidifying all kinds of soil, especially relate to a kind of for to the curing of Soft Ground, mat formation, foundation works, the curing sub-surface of foundation of sea floor construction work and the powdery soil solidifying agent (all materials that can improve the soil technology performance are called soil-solidified-agent) of subbase.
Background technology
Development along with society, all trades and professions engineering construction demand is also increasing, and traditional engineering construction needs a large amount of natural resourcess, fried mountain rubble, Wa He adopt sand, not only destroyed physical environment, and original sand, stone material can not satisfy growing engineering construction demand far away.In town road, the road construction of China are put into practice, generally adopt curing compound (cement class, lime, cement and lime class, lime fly ash class etc.) to be stablized great soil group subbase, basic unit.Above-mentioned semi-rigid great soil group subbase, basic unit have the strength and stiffness that need, but also have some defectives, and main manifestations is:
(1) easily produce shrinkage crack.
Be exposed to the sun if there is no covering protection or health untimely, unavoidably to produce desciccation crack; Frost region also may produce the crack that temperature contracts and drying shrinkage combines.
(2) influenced by environmental temperature.
Suffer multigelation, its intensity can descend.When being attended by the free water immersion, even can wreck.
(3) problem of environmental pollution
Lime, cement, flyash easily form harmful dust in construction process.Seeking more economical rational sub-surface and subbase course material, is one of problem of present positive broad research in the world and practice.In rudimentary highway and be usually without the road surface highway, road conditions are poor, dust is many, " fine day is ash all over the body, the rainy day mud ", the labour intensity of maintenance and maintenance costs remain high.
If can directly take most economical on the earth, engineering materials---the soil the most widely of originating in engineering construction; just can greatly save the consumption of sand, stone; can be when guaranteeing that national project is built development need; also reduced the destruction exploitation to natural resources, natural ecological environment has been played the active protection effect.Therefore, in line with the principle of Sustainable development and " innovation is autonomous, scientific development for energy saving, environment protection ", need that research and development are a kind of can save public resource badly, have again the soil-solidified-agent of environmental-protection function.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of top layer that is applicable to various soil conditions, the deep layer soil body and newly-built and reconstruct the curing sub-surface of urban roads at different levels, highway, building lot and the powdery soil solidifying agent of subbase.The technical scheme that the present invention solves its technical problem employing is: the powdery soil solidifying agent of a kind of curing sub-surface and subbase, and the component that it contains and parts by weight are:
Technical problem to be solved by this invention also can further be solved by following technical solution: the model of Repone K is Potassium chloride; The model of sodium-chlor is sodium sulfate, anhydrous; The model of magnesium chloride is magnesium chloride; The model of sodium sulphite is sodium sulfate, anhydrous; The model of calcium chloride is Calcium chloride; The model of tripoly phosphate sodium STPP is sodium tripolyphosphate.
Repone K in the present invention (KCl) energy binder soil soil particle consists of reticulated structure in cured body, form early strength; Sodium-chlor (NaCl) has surface-active action and delayed coagulation, makes it more easily enter soil particle inside, thereby makes ion exchange reaction carry out rapidly, thoroughly, can also adjust time of lag of the present invention simultaneously; Magnesium chloride (MgCl2) can with clay mineral generation chemical reaction, make up the deficiency of reticulated structure intensity, form later strength, thereby improve the consolidated earth mass final strength; Sodium sulphite (Na2SO4) is when consolidated earth mass suffers water soaking for a long time, and itself and water can form a kind of balance material, thereby avoids water to the etch of consolidated earth mass, makes with tying not argillization of the soil body, intensity stabilization; Calcium chloride (CaCl2) plays the effect that excites early strength; Tripoly phosphate sodium STPP (Na5P3010) can with other component reaction, the resultant volume of formation is increased, and separate out gel-like substance, fill the hole of consolidated earth mass inside, cause the consolidated earth mass volume to occur to a certain degree to expand, produce internal stress, thereby improved impervious, nonshrink, frost resistance and the fatigue performance that solidifies the soil body.The present invention's each component material used all adopts the commercially available prod.The present invention is main formulated by inorganic salt, so can not pollute, can harden in seawater and fresh water, and have high temperature resistant, the performance of the corrosion of have good effect in acid alkali and durable.The present invention is powdery, and its preparation method is uniform stirring.The present invention is owing to adopting technique scheme, solidify applicable to the top layer of various soil conditions, the reinforcing of the deep layer soil body, intensity, weather resistance, the economy of building lot have been strengthened, and traditional roadbed subsidence, the fracture that often faces, the difficult problems such as slurry, protuberance of falling of constructing of effective solution, extend Road Service Life, reduced the Road maintenance cost.The Chinese government attaches great importance to the introduction exploitation of above-mentioned soil-solidified-agent, and " soil-solidified-agent introduction development and application " classified as one of 33 transport science and techonologies main projects drafting enforcement before 2010.Soil-solidified-agent is called one of greatest invention of 20th century by U.S.'s " Engineering News Record ", is referred to as the type material of 21 century by Japan, is adopted as the preferred option of developing country's backroad laying of roadway by the World Bank.
