Description
Technical field
The utility model relates to highway construction construction test ancillary equipment fields, and in particular to a kind of measurable height of specimen
Vertical vibration compaction test apparatus, for can measure height of specimen vertical vibration compaction test apparatus form cement stabilizing test specimen and pitch mixing
Expect the measurement of height of specimen.
Background technique
Vertical vibration compacting process shaping test piece is generallyd use, just can measure the height of test specimen after test specimen need to being demoulded.Due to
Height of specimen needs just to be capable of measuring after demoulding, and no matter uses the stripper of which kind of form, can all reduce working efficiency.And test specimen is de-
It when carrying out elevation carrection after mould, is generally measured at test specimen edge using vernier caliper, but after test specimen hits reality, generally at edge
The mixture for having part of cement and aggregate chips (sand), which is slightly above immediately below vibration hammer, hits real face, this part in native sample compacting at
For remaining soil height.Since remaining soil height is different in test, or higher than hitting real face, or do not hit it is real and lower than hitting real face, so as to cause
Test data dispersion, and remaining soil height increases, and dry density is less than normal；Remaining soil height reduces, and dry density is bigger than normal.
Molding for cement stabilized type test specimen, maximum dry density, optimum moisture content selection during, test data
It can be fitted to a convex parabola, stationary point corresponds to maximum dry density and corresponding moisture content.If the height of test specimen is without foot
Enough accuracy, it is stationary point that small error, which can be fitted to practical optimum moisture content or so two o'clock,.If moisture content is less than normal, i.e. cement
Dosage is bigger than normal, and site operation is instructed to be also easy to produce desciccation crack, influences pavement quality, and increase construction cost, causes to waste；If containing
Water rate is bigger than normal, i.e., cement dose is less than normal, and cement slurry cannot be bonded together thick, fine aggregate, and base layer structure is loose, is not achieved and wants
The compression strength asked, the quality of roadbed quality are directly related to the use quality of whole highway.
Therefore, do not have representativeness, measurement result inaccuracy, the accuracy of measurement to the measurement result of test specimen brim height
It is not high.The height of test specimen will have a direct impact on the optimum moisture content of cement stabilized type test specimen and the accuracy of cement dose, Jin Erying
Ring the construction cost and quality of roadbed.
