Description
Technical field
A kind of free bleeding rate of inflatable grouting agent and free wxpansion test instrument are the utility model is related to, belongs to grouting agent certainly
By bleeding rate and free wxpansion test apparatus field.
Background technology
The free bleeding rate of grouting agent and free wxpansion test instrument are the dilatancy and swell-shrink characteristics for reflecting something
Test apparatus, its principle are that the slurry that will be stirred is slowly injected into test chamber, load slurry volume 800ml ± 10ml.
After slurry injection, using water conservation diaphragm seal upper opening of container, it is statically placed on horizontal plane, slurry height h1 is recorded after standing 1 minute,
It is measured after standing 24 hours and isolates the height h3 of water surface elevation h2 and slurry expanding noodles, then calculates bleeding rate as follows
And expansion rate.
Though the free bleeding rate of existing grouting agent and free wxpansion test instrument can determine the free bleeding rate of grouting agent and freely swollen
Expansibility, but during use is tested, however it remains some problems, it is in particular in：The grouting agent for having grouting material is freely secreted
Water rate and free wxpansion test instrument are not easily taken out in standing 24h post jacking material, cause existing test instrument to reuse.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of free bleeding rate of inflatable grouting agent and free wxpansion
Test instrument, it is easy to take out the grouting material after standing 24 hours, the situation for overcoming test instrument to reuse, can overcomes existing
The deficiency of technology.
The technical solution of the utility model is：A kind of free bleeding rate of inflatable grouting agent and free wxpansion test instrument, it
Including base, be provided with base it is closable inflate hole, be provided with base tubular the free bleeding rate of grouting agent and from
By expansion-pressure testing apparatus, capping is provided with the upper end of the free bleeding rate of grouting agent and free wxpansion test instrument.
The material of the free bleeding rate of above-mentioned grouting agent and free wxpansion test instrument is lucite, and its diameter 100mm is high
120mm, wall thickness 5mm.
Prior art compares, the free bleeding rate of the utility model inflatable grouting agent and free wxpansion test instrument, in base
The closable free bleeding rate of grouting agent and free wxpansion test instrument inflated hole, tubular is provided with base is provided with,
The upper end of the free bleeding rate of grouting agent and free wxpansion test instrument be provided with capping, such device complete test after, pass through by
Device inverts, and allows bottom-up, is made a call to bottom five, six times gas with demoulding Special gun and can just be taken out test specimen, whole after test specimen taking-up
Reason can totally give over to next use；The material of the free bleeding rate of grouting agent and free wxpansion test instrument is lucite, and its is straight
Footpath 100mm, high 120mm, wall thickness 5mm, this is the criterion for both guarantee tests data that applicant draws after test of many times
The size of operation is not influenceed again.
Brief description of the drawings
Fig. 1 is attachment structure schematic diagram of the present utility model.
Wherein, base 1；Inflate hole 2；Starch the free bleeding rate of agent and free wxpansion test instrument 3；Capping 4.
Embodiment
Embodiment 1. is illustrated in fig. 1 shown below, and a kind of free bleeding rate of inflatable grouting agent and free wxpansion test instrument, it is wrapped
Include base 1, be provided with base 1 it is closable inflate hole 2, be provided with base 1 tubular the free bleeding rate of grouting agent and
The material of free wxpansion test instrument 3, the free bleeding rate of grouting agent and free wxpansion test instrument 3 is lucite, its diameter
100mm, high 120mm, wall thickness 5mm, capping 4 is provided with the upper end of the free bleeding rate of grouting agent and free wxpansion test instrument 3.
When in use, with a fritter paper before grouting liquid is filled out toward the free bleeding rate of grouting agent and free wxpansion test instrument 3
Stomata is covered.Tank cement mortar about 100mm depths are filled out in toward the cavity of the free bleeding rate of grouting agent and free wxpansion test instrument 3, are surveyed
The filling face of filling out height simultaneously records, and then covers tightly.Its separating water water surface and cement mortar expanding noodles are measured after putting 3h and 24h;It is solidifying taking
It is during solid pressure slurry that the free bleeding rate of grouting agent and free wxpansion test instrument 3 is inverted, allow it is bottom-up, with the demoulding Special gun
Inflate hole 2 to bottom and beat gas under 5-6 and test specimen can just be taken out, after the demoulding, cavity clean it up can be left into time use.
