Description
Technical field
The invention belongs to foundation treatment technology field, particularly relate to a kind of airport occasional passage strong cement soil treatment soon
Method.
Background technology
At present, in engineering, often use cement is as filler, to improve soft soil foundation.Soil cement is by cement and natural rock-filled
The manipulated soil mixed by mechanical agitation.Owing to the performance of soil cement is good, material source is wide, easy construction, and price is low
Honest and clean, therefore it is widely used to improve ground and the retaining wall etc. of foundation ditch, by mixing a certain amount of cement, after compacting, soil matrix
Intensity, stability and deformation modulus can be greatly improved, so that soil matrix mechanical property is optimized.
In airport occasional passage is built, owing to the present control to fast strong cement land-based construction lacks theory support, because of
This determines that in real work the parameter major parts such as cement mixed weight, early strength agent mixed ratio, compactness are still by workmen's root
Determine according to experience, and lack fast strong cement soil matrix treatment technology and theoretical basis.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of airport occasional passage strong cement soil treatment soon
Method.
In order to achieve the above object, the airport occasional passage that the present invention provides strong cement soil matrix processing method soon includes by suitable
The following step that sequence is carried out:

Degree is in interior soil matrix physical index；
2) determine the width of the airport occasional passage with fixed length and process the degree of depth, thus calculating the body of pending soil matrix
Long-pending, and calculate the gross mass of pending soil matrix according to volume and above-mentioned soil body dry density, the soil property that then determines according to above-mentioned,
Soil moisture content determines cement mixed weight, early strength agent incorporation by the addition accounting for pending soil matrix gross mass 5%～15%, and
Determine compactness；
3) above-mentioned pending soil matrix is divided into multiple sash, and according to step 2) in the ratio that determines calculate each frame
Cement and the consumption of early strength agent in lattice；
4) cement and early strength agent are put into each sash mix homogeneously by above-mentioned consumption, then utilize paver to pave
In whole sash, utilize the abundant mix of lime-soil mixing machine afterwards, stop after sampling Detection is qualified；
5) utilize vibrating roller press quickly to flatten in the range of pending soil matrix to roll to above-mentioned steps 2) compacting that determines
Carry out maintenance after degree and can complete whole processing procedure.
In step 1) in, the described original soil base to airport occasional passage is reconnoitred, aqueous to determine soil property, the soil body
Rate and soil body dry density comprise the steps: in the method for interior soil matrix physical index
1.1) soil layer of occasional passage earth's surface, airport 30cm band root system of plant is removed, by the cutting ring of known quality by burying
Layer, then has related for cutting ring surrounding and determines that the soil body of volume digs out, with geotechnique's cutter by upper and lower for cutting ring surface and the side soil body
Elimination is scabbled, and weighs cutting ring and the gross mass of the soil body, thus obtains soil body gross mass；
1.2) take about 2kg wet soil, with seal bag good seal, then with the aluminum box of known quality take from wet soil 15～
30g soil sample, weighs aluminum box and the gross mass of wet soil, carries out baking test, weighs dry ground and the gross mass of aluminum box, thus obtains soil
Body moisture content, afterwards integrating step 1.1) in soil body volume and soil body gross mass obtain soil body dry density；
1.3) by step 1.2) in residue wet soil dry, carry out liquid model limitation test, obtain the liquid limit of regional, plastic limit with
And plasticity index, thereby determine that out soil property.
In step 2) in, when described soil moisture content is 15%～25%, cement mixed weight accounts for the total matter of pending soil matrix
The 5%～15% of amount, early strength agent incorporation is the 10% of cement mixed weight, and compactness is 90%～96%.
In step 4) in, the size of described sash is 5m × 4m.
In step 4) in, the described method utilizing the abundant mix of lime-soil mixing machine is: along sash length side in sash
At the uniform velocity walking in S font, scene takes the 5m/min speed of travel, to guarantee that mix is uniform, the degree of depth is consistent；Per pass overlap joint during mix
Width is no less than 30cm, it is ensured that mix without leakage in working area, most mixs twice.
In step 5) in, the described vibrating roller press that utilizes in the range of pending soil matrix quickly flattens the method rolled
It is:
5.1) first using 20t heavy-duty shocks chaser to roll in a sash, during beginning, quick static pressure enters for 1 time
Row front cover, to prevent what soil mass water from dividing scatter and disappear too early and carry out the most levelling of surface, the most at the uniform velocity weak shock 1 time, macroseism 4～6
Time, until reaching required compactness；
5.2), after often completing the rolling an of sash, linearly complete rolling of unilateral all sashes, then turned around
Rolling of opposite side sash.
Having the beneficial effects that of the airport occasional passage that the present invention provides strong cement soil matrix processing method soon: the present invention uses
The test of various working scheme obtains optimum cement mixed weight, for different natural moisture contents, determines that soil compaction degree, cement mix
Amount, early strength agent addition optimal case, make soil matrix intensity timeliness double.
