Abstract
The present invention relates to the technical field of chemical curing agents, and in particular relates to a sludge waste soil curing agent. The curing agent comprises the following materials by weight: 20-30% of cement, 10-25% of sodium metaaluminate, 10-20% of calcium nitrate, 5-10% of gypsum powder, 1-5% of sodium lignin sulfonate, 1-5% of sodium dodecyl sulfate and 1-5% of triethanolamine. The purpose of the present invention is to provide the sludge waste soil curing agent which is small in pollution, low in cost and high in efficiency.
Description
Technical field
The present invention relates to the technical field of chemical curing agent, specifically a kind of mud roach solidifying agent.
Background technology
Along with the fast development of national economy, the quantities of geotechnical engineering construction (as prospecting probing, castinplace pile and construction of diaphragm wall, anchoring engineering, hydrological well, water-stop curtain, non-excavating construction etc.) is doubled and redoubled, and thus creates a large amount of waste muds in engineering construction.Because engineering construction is given up the dispersiveness (being dispersed in each workyard) and disguise (relative to construction noise) that slurry produces, the engineering slurry that gives up is difficult to be focused on, and causes larger pollution to environment.Existing processing mode is, with groove tank car, on-the-spot slime water is transported to refuse tip, countryside, allows its natural mummification.The original backwardness of this processing mode, creates many problems.One is need a large amount of land occupation resource; Two be costly, efficiency is low, construction peak period, groove tank car transports round the clock and still can not meet construction speed requirement; Three is working-yard bad environments, and slime water overflows and makes us being difficult to participate, and construction brigade is often because the slime water water drain that bleeds causes line clogging and suffers significant fine; Four is that groove tank car is also normal in transit pollutes city appearance environment etc. because slime water leakage is sprinkled upon on arterial highway, city.Along with the development of technology, the process of mud be have also appeared to the techniques and methods such as sealing in hole, soil cultivating (biological degradation), mummification, pressure break injection, freezing, the MTC (mud is converted into cementing slurry) of landfill, burning, solidification.Integrated comparative, current domestic slurry curing method is still immature.Rational technology, the mud waste innoxious process for treating that simple to operate, cost, practicality are the strongest are also in research and development.Slurry curing technology mainly by adding solidification admixture method, makes mud farthest solidify, thus carries out earthing and restore abandoned land to cultivation or carry out other construction after meeting certain solidification intensity.At present; the requirement of building extensive railway, highway, municipal administration etc. along with the Environment Protection Policy of country is more and more higher; traditional pile foundation slurry treatment process (burying everywhere) can not meet the demands; in the urgent need to a kind of slurry curing material being applicable to construction site, so that the construction of better serving each building pile foundation treatment of mud is produced.
Summary of the invention
The object of the invention is to be to provide a kind of pollute little, cost is low, high efficiency mud roach solidifying agent.
The technical solution used in the present invention is, a kind of mud roach solidifying agent, described each material is by following weight percent composition: cement 20-30%, sodium metaaluminate 10-25%, nitrocalcite 10-20%, terra alba 5-10%, sodium lignosulfonate 1-5%, sodium lauryl sulphate 1-5%, trolamine 1-5%.
Advantage of the present invention has saved the natively comparatively nervous land resources of China after carrying out effective solidification treatment to mud, achieve mud farthest to solidify, thus carry out earthing and restore abandoned land to cultivation or carry out other construction after meeting certain solidification intensity, there is good economy and social benefit.
Embodiment
The present invention is further described with the following Examples.
Embodiment 1, a kind of mud roach solidifying agent, described each material is by following weight percent composition: cement 30%, sodium metaaluminate 10%, nitrocalcite 20%, terra alba 5%, sodium lignosulfonate 5%, sodium lauryl sulphate 1%, trolamine 5%.
Embodiment 2, a kind of mud roach solidifying agent, described each material is by following weight percent composition: cement 20-30%, sodium metaaluminate 25%, nitrocalcite 10%, terra alba 10%, sodium lignosulfonate 1%, sodium lauryl sulphate 5%, trolamine 1%.
Embodiment 3, a kind of mud roach solidifying agent, described each material is by following weight percent composition: cement 25%, sodium metaaluminate 18%, nitrocalcite 15%, terra alba 7%, sodium lignosulfonate 3%, sodium lauryl sulphate 3%, trolamine 3%.
Should be understood that this embodiment is only not used in for illustration of the present invention to limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the protection domain that the application's appended claims limits equally after having read the content that the present invention lectures.
