Abstract
The invention relates to a treatment method for saturated over-wet soil, and relates to a treatment method for over-wet soil. The problem that saturated over-wet soil cannot be effectively treated in the prior art is solved. The technical scheme is as follows: comprises the following steps: measuring the natural water content of the soil and reducing the natural water content by a vacuum preloading method; the over-wet soil curing material comprises 1-12 parts of cement, 0-12 parts of lime and 0-0.02 part of soil curing agent by weight calculated according to 100 parts of dry soil of saturated over-wet soil to be treated; removing the vacuum prepressing equipment after the natural water content is reduced to below 30 percent, ploughing, crushing and leveling the soil, and uniformly spreading 2/3 over-wet soil curing material with specified dosage on the soil; ploughing, mixing and rolling; carrying out material sealing on the rolled soil layer; and uniformly scattering the residual over-wet soil solidifying material on a soil layer, and then turning, stirring and crushing the soil until the soil particles are below 30 mm. The method is mainly applied to the treatment of saturated and over-wet soil in a humid area.
Description
Technical field
The present invention relates to a kind of over-wet soil processing method, particularly relate to a kind of method of disposal to saturated over-wet soil.
Technical background
In moist area of heavy rainfull, the time in rainy season is long, amount of precipitation is big, and groundwater table is high in addition, and foundation soil usually was in wet even saturation state.The over-wet soil water content of moist area of heavy rainfull is high, and bearing capacity is low, poor stability, easy deformation." spring " phenomenon usually appears during construction, and can't compacting; After the completion, under the effect of traffic load, very easily cause subgrade and pavement to produce destructions such as depression, distortion, frost boiling, unstability.According to existing subgrade Design job specfication, over-wet soil can't meet the demands, and often can only do the side's of abandoning processing, yet moist area of heavy rainfull lacks high quality filler, change fill out time-consuming.Fill out even change, original ecological environment all will be destroyed in excavation district and the spoil area changed after filling out, cause hostile environment influence and social influence.
Punishment and utilization for over-wet soil; Domestic and international project circle has proposed many punishment methods; But these methods mainly are to the saturated far away over-wet soil of water content, for then generally taking airing near saturated or saturated over-wet soil or directly changing the method for filling out.In moist area of heavy rainfull, very long and sunshine in rainy season, fate was very limited, and the use of airing method has significant limitation; Adopt cushion then can cause than havoc to peripheral ecological environment.Therefore, these two kinds of methods are not too to be suitable in moist area of heavy rainfull.
Except airing method and cushion, the saturated over-wet soil roadbed filling of domestic engineering bound pair also directly effectively do not punish and utilize method, the saturated over-wet soil of especially moist area of heavy rainfull.
Summary of the invention
The objective of the invention is in order to overcome the deficiency that prior art exists; Propose a kind of punishment of saturated over-wet soil and utilize method; This method is mainly used in moist area of heavy rainfull, have the punishment effect better, economical, can be in rainy season construction, do not receive characteristics such as weather effect, environmental protection.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of punishment method that is used for saturated over-wet soil comprises the following steps:
(1) natural moisture content of mensuration place soil;
(2) adopt vacuum method to reduce the natural moisture content of saturated over-wet soil;
(3) preparation over-wet soil curing materials heavily is that the over-wet soil curing materials comprises 1～12 part of cement, 0～12 part in lime, 0～0.02 part of soil-solidified-agent under 100 parts of weight situation about calculating according to the dry ground of the saturated over-wet soil of required processing;
(4) after (2) make the soil natural moisture content reduce to 30% below through step, remove vacuum preloading equipment, with soil turn over, broken 1～2 time, after flattening processing with the even spreading of over-wet soil curing materials of prescribed dose 2/3 on it;
(5) with place soil turn over, mix 4～6 times, roll then one time comprehensively;
(6) the soil layer shelving 24～28h to tentatively rolling;
(7) the over-wet soil curing materials with remaining prescribed dose 1/3 evenly spreads on the soil layer, and row turns, is crushed to soil particle below 30mm again, rolls at last to get final product.
In such scheme, the over-wet soil curing materials in the said step (4) comprises cement 4-8 part, lime 5-9 part, soil-solidified-agent 0.005-0.015 part.
Can find out that from the characteristic of the invention described above its advantage is: it is better that this method is not only punished effect, comparatively economical, and can not receive weather effect in rainy season construction, can not damage peripheral ecological environment simultaneously.
