The depth of the piston pushed into the piston cylinder can be accurately measured; the pressure of gas inside the piston cylinder is accurately controlled; an operation is simple and convenient; data are stable and reliable.
Description
Technical field
The utility model relates to a kind of equipment that detects roadbed filling density, relates in particular to a kind of gasbag-type volume automatic analyzer.
Background technology
The density measurement of soil is to detect one of main experimental of Subgrade Compaction Quality, and its test method comprises core cutter method, the method for sealing with wax, sand replacement method, douche, air-bag method and nucleon rays method etc.
In prior art, the test apparatus of air-bag method is gasbag type volume measuring apparatus, and the principle of work of this instrument is according to Robert Boyle (Boyle) law, and, under uniform temperature condition, gas in sealed vessel pressure and gas volume product are a constant.At present, the gasbag type volume measuring apparatus that air-bag method test adopts is mainly comprised of air bag, cylinder barrel, piston, hollow piston rod, sacculus, glass water gauge, digital display survey chi, protect that hole is encircled etc.To testing pits, inflating, while measuring its volume test, needing to promote piston downwards, until solution water column rises to water level graticule, then reading and recording digital display staff reading, calculating test findings.
Mainly there is following shortcoming in above-mentioned prior art:
While promoting piston, in piston, gaseous tension reflects by solution height, and water level graticule is to set according to instrument rated pressure that piston adds and solution density, when judging whether solution water column rises to water level graticule, not easy to operate, and is difficult to accurately control gaseous tension; Because compressed gas volume is with change in pressure, so pressure variation is influential to test volume; In addition, instrument is at carrying and when test, glass water gauge cracky.
