Abstract
The invention provides a soil solidifying material used for over-wet soil and a use method thereof, relating to a soil solidifying material and a use method thereof, aiming at providing the soil solidifying material used for over-wet soil with good reinforced effect and strong solidifying soil water stability and the use method thereof. The technical scheme of the invention is as follows: the soil solidifying material used for over-wet soil comprises the following components in parts by weight calculated by supposing that the over-wet soil needs to be treated is 100 parts by weight: 1-8 parts of soil solidifying agent, 1-10 parts of lime, 0-8 parts of cement and 0-20 parts of coal ash. The use method comprises the following steps: grinding and levelling the soil, evenly spreading the soil solidifying material on the soil; grinding, blending and laminating the soil solidifying material and the over-wet soil together; carrying out material enclosing on the soil layer which is initially laminated for 24-28 hours; and evenly spreading the soil solidifying material on the soil layer again, then stirring, grinding and compacting. The invention is mainly used for the treatment of over-wet soil.
Description
Technical field
The present invention relates to a kind of soil curing material and using method thereof, particularly relate to a kind of soil curing material and using method thereof that in the highway subgrade construction, is used for over-wet soil.
Background technology
Roadbed is the basis on road surface, is the important component part of highway, and it and road surface play a part to bear traffic load jointly.The construction quality of roadbed is directly connected to the construction quality of whole highway engineering.The intensity of roadbed and stability are the prerequisites that guarantees pavement strength and stability, do not have firm, stable roadbed, just do not have firm road surface.In the highway subgrade construction process,, run into the filling roadbed situation of over-wet soil that adopts through regular meeting owing to be subjected to restrictions such as weather, construction period and geologic condition.
Over-wet soil is meant the filler natural consistency less than a certain permissible value, or the optimum moisture content determined greater than compaction test of water content must take related technical measures to be handled the soil that can be compacted to the regulation compactness when too much." highway subgrade construction technique normalizing " (JTJ033-95) is considered as over-wet soil with natural consistency less than 1.0～1.1 cohesive soil.
Because the natural moisture content of over-wet soil is big, viscosity is big, generally also contains the swelling property mineral substance, and its wetting ability and retentiveness are strong, bad hydraulic permeability, and airing difficulty and difficult the pulverizing, in highway subgrade construction, its difficulty of construction is big.Therefore, want to make the degree of compactness of over-wet soil filler to reach compacting criteria, just must take appropriate measures, otherwise through rolling, redundant moisture can not all be discharged from the soil, cause roadbed " springing " to occur.
In the punishment to over-wet soil, using additive that over-wet soil is carried out stable curing is method relatively more commonly used.The stable curing of soil, through long term studies, the method for soil-solidified-agent stable curing soil is maximum method that adopts at present.In present existing over-wet soil punishment method, solidifying agent such as traditional solidify material such as lime, cement, flyash and the EN-1 of road nation are adopted by actual engineering, owing to be to adopt more simple material all, so the punishment effect is not very good: handle such as the simple lime that adopts, indexs such as the intensity of the soil body, CBR value, the modulus of resilience have bigger lifting after handling, but water stability is relatively poor; Simple use the road EN-1 of nation solidifying agent then processing costs is comparatively expensive or the like.For the effect that how to improve soil solidification, and not excellent research and the enforcement in the prior art of the mode of needed material and employing.
Summary of the invention
The objective of the invention is for a kind of soil curing material that is used for over-wet soil is provided, this solidify material has that consolidation effect is good, the solidified earth water stability is strong and be easy to marketing etc., and another object of the present invention provides the using method that above-mentioned soil curing material is used for the highway subgrade construction.
The objective of the invention is to realize: a kind of soil curing material that is used for over-wet soil by following technical proposal, according to the over-wet soil of required processing is under 100 parts of weight situation about calculating, and comprises the component with following weight: Gu 1～8 part of native agent, 1～10 part in lime, 0～8 part of cement, 0～20 part in flyash.
A kind of using method that is used for the soil curing material of over-wet soil comprises the following steps:
(1), over-wet soil is transported to job step one side after being dug out by ditch, is pushed on the job step with dozer after preliminary airing again, soil is pulverized, and after leveling is handled, with the even spreading of soil curing material on it;
(2), soil curing material and over-wet soil are pulverized mix together, roll then;
(3), the soil layer shelving 24～28h to tentatively rolling;
(4), even spreading soil curing material once more on the soil layer, turn, be crushed to soil particle then below 30mm, last cal rolling is also checked compactness.
The consumption of the soil curing material in the described step (1) is 2/3 of the regulation total amount, and the consumption of the soil curing material in the step (4) is 1/3 of the regulation total amount.
From product of the present invention and method feature as can be seen, the invention has the advantages that: solidifying agent material of the present invention and using method thereof can make the plasticity index of over-wet soil reduce, clay content reduces, the swell increment of soil is effectively controlled, and increases the intensity and the stability of soil; Solidifying agent material eliminates of the present invention traditional solidify material handle the drawback of the water stability difference that over-wet soil brings, reach and utilize current material, avoid repetition and waste, improve the purpose of subgrade strength and water stability.
