Description
Technical field
The present invention relates to tunnel groutings and the prominent mud Treatment process field of gushing water, and in particular to a kind of slip casting sample preparation dress
It sets, is primarily adapted for use in the laboratory test of rich water decomposed rock tunnel grouting simulation and gushing water Study on treatment technology.
Background technique
During rich water decomposed rock tunnel construction, since formation strength and stability are low, easily produced under construction disturbance
Raw prominent discharge disaster, or even cause tunnel structure destruction, surface subsidence, house crack and the secondary disasters such as the source has dried up, engineering
In frequently with slurry injection technique improve formation strength and stability.The science of grouting program, which is formulated, to be unable to do without to by slip casting stratum object
The exact test measurement of reason, mechanical index.Live survey in situ is divided into for the measurement test of slip casting Rock And Soil physics, mechanical property
It tries and two kinds of laboratory test.Live in-situ test be exactly the location of the original basic natural structure for keeping the soil body of soil layer,
Under natural moisture content and natural strain condition, the engineering mechanics property index of soil is measured.Although it can quickly and completely be obtained
The engineering character parameter for reflecting slip casting Rock And Soil characteristics of macrostructure is negated, but since test period is long, in human and material resources and time
Larger, the limiting factors such as at high cost of upper consuming so that people are many times having to abandon the testing scheme, then use room
The method of interior test carries out injecting cement paste index test.Slip casting sample used by the key of laboratory test success or not is that
Whether engineering adaptability is good.
Current stage, the method for laboratory test are as follows: indoor simulation sample production mainly control simulation sample density,
Moisture content and porosity are consistent with undisturbed soil, then then use grouting serous fluid and simulation for the simulation of soil nature slip casting reclamation element
Soil body uniform stirring.Method particularly includes: according to the grain density and moisture content of undisturbed soil, by the soil with corresponding grain density
The water and grouting serous fluid of grain and corresponding proportion stir evenly, and then measure the physical index of the slip casting soil body again.
This laboratory test mode, simulation sample made by one side cannot react the space of undisturbed soil itself well
On the other hand the characteristics such as structure, intersection construction, folded aggressiveness can not simulate slurries during slip casting to the infiltration of the soil body, compacted
And influence of the splitting channel to soil capability caused by slabbing action.
Therefore, the indoor simulation slip casting for how making energy accurate response soil body natural structure and natural strain condition is real
Test sample and have become a problem urgently to be resolved, be badly in need of inventing it is a kind of efficiently, be reliable, easy to operation can react day
Right soil body original state characteristic and the grouting sample preparation device that slabbing action can be simulated.
Summary of the invention
In view of the foregoing deficiencies of prior art, the purpose of the present invention is at least that provide a kind of slip casting sample preparation dress
It sets, can be obtained and can accurately reflect the original state soil body day under conditions of removing live in-situ test from and only carry out laboratory test
