Description
Technical field
This utility model relates to a kind of cementitious test device, particularly relates to a kind of cementing examination of microorganism induction tosca
Experiment device.
Background technology
For basement process frequently with method be utilize artificial material (cement, epoxy resin, sodium silicate etc.) by fill
The method of slurry is injected in hole to reach cementing effect.For above chemical grouting in addition to sodium silicate, remaining
Chemical slurry the most in various degree containing noxious substance, can be to environment.In recent years, along with biology, change
, mechanics and the multi-disciplinary crossing research of materialogy, a kind of new technique microorganism induction tosca technology
(MICP) it is unfolded research.
During carrying out cementitious test, inject bacterium solution according to by container head to bottom, due to the impact of wall effect,
When bacterium solution major part by limit wall seepage flow and carries out cementitious test to the soil body that compactness is higher, the problem of its bacterium solution infiltration is relatively
It is prominent.Though if use by container bottom to top inject bacterium solution mode can solve bacterium solution distribution problem, but with reality
Border experiment does not corresponds.In addition internal binding material after frequently resulting in mineralization due to the skewness of bacterium solution in filling process
Spatial and temporal distributions is uneven, and it is poor to ultimately result in cementing effect；Poor for the soil body permeability of low porosity, cementing strength is low.
To sum up, current microorganism induction tosca test indoor set still suffers from some shortcomings.
In order to avoid the appearance of problem above and preferably carry out microorganism induction tosca cementitious test, need to grind
Make new microorganism induction tosca cementitious test device.
Summary of the invention
This utility model provides a kind of microorganism induction tosca glue for solving technical problem present in known technology
Knot assay device, uses this device to carry out laboratory test, and bacterium solution is in process of osmosis, and spatial and temporal distributions is uniform, for low hole
The soil body permeability of gap rate is good, and cementing strength is high.
This utility model is adopted the technical scheme that by solving technical problem present in known technology: one microorganism lures
Leading tosca cementitious test device, including sand post, the center of top at described sand post is provided with import, at described sand post
Inside it is provided with the geotextiles covered on the sample soil body, described geotextiles is formed with sand gravel layer, under described sand post
End is connected with porous disc, is provided with the middle storage post affixed with it in the lower section of described porous disc, in described middle storage post
Bottom be provided with liquid outlet, the liquid outlet of described middle storage post is connected with the import of peristaltic pump II by pipeline, described compacted
The outlet of dynamic pump II is connected with liquid holding dish；Import at the liquid outlet and the described peristaltic pump II that connect described middle storage post
Described pipeline is provided with valve；The import of described sand post is connected with the outlet of peristaltic pump I, the import of described peristaltic pump I with
Microorganism slurry pool connects.
The import of described sand post is provided with shower nozzle.
It is connected with rule in the outside of described sand post.
This utility model has the advantage that with good effect: uses a peristaltic pump that microorganism serosity is pressed into sand post, adopts
Bacterium solution can be made to ooze down the mode of microorganism serosity sucking-off sand post with another peristaltic pump, it can be ensured that bacterium solution
In process of osmosis, spatial and temporal distributions is uniform, and the soil body permeability for low porosity is good, and cementing strength is high；This reality simultaneously
Bidirectional experimental is realized, it is possible to be applicable to test the cementitious test under various soil mass, different bacterium solution injection mode with novel,
Test data is the most reliable.Also to have simple in construction, the sample soil body readily accessible and easy to operate for this utility model simultaneously
Advantage.
