Background technology
The mensuration of the degree of compaction of soil sample, is be all a basic job for scientific research personnel or the technical staff at scene, is also the important step in teaching or engineering construction.When carrying out construction, if ground soil's water content is too high, the hole of soil sample is relatively larger in other words, can cause when the later stage constructs, ground settles, and makes structure destroy, so only when soil sample meets the designing requirement of dry density and water content, utilize theoretical knowledge, it is judged that its largest settlement；Test analysis to the optimum moisture content of various sands, for engineering is also an important problem, earth work experiment should measure maximum dry density and the optimum moisture content of soil, it it is the critical problem of engineering construction to the filling construction whether carrying out next step earth material, the compactness of on-the-spot soil sample to be detected is taked to be the most frequently used traditional method with core cutter method, scene being carried out after soil sample takes, take back laboratory and carry out the test analysis of each index；Indoor earth work experimental result, if the feature of natural soil sample can be carried out reasonably simulation is that comparison is crucial.Current mine ground laboratory, is typically all employing and rams in closely knit soil by cutting ring, tamp with mallet, then is loosened by soil around cutting ring with pick, just can carry out closely knit soil sample afterwards and originally produce, and producing soil sample wastes time and energy, and inefficient.For engineering construction, great majority are after artificial sampling at the scene, after carrying out artificial compacting with weight, then carry out test analysis, and its artificial intensity is big, and step is cumbersome.
Summary of the invention
In order to improve the problems referred to above, time this utility model one earth work experiment closely knit soil device for making provides a kind of earth work experiment, prepare the device of close sand soil sample, it is possible to be effectively improved closely knit soil sample and originally produce efficiency, reduce the working strength that sample is produced.
This utility model one earth work experiment closely knit soil device for making is achieved in that this utility model one earth work experiment closely knit soil device for making is made up of subject support means and sample placing device.nullSubject support means is by motor、Fixing bearing、Spiral sleeve、Spiral guide rod、Mobile sleeve pipe、Depression bar、Overflow-prevention cover plate、Main body rack、Pressing plate、Gag lever post、Stop collar、Connecting rod、Line shaft forms，Motor is placed on main body rack，Fixing bearing is placed on main body rack，Line shaft one end is placed on motor，The other end connects through fixing bearing and spiral guide rod one end，Spiral guide rod is placed in mobile sleeve pipe one end，Depression bar one end is connected with the mobile sleeve pipe other end，Pressing plate is placed on the other end of depression bar，Overflow-prevention cover plate is placed on depression bar，The other end of spiral guide rod is placed in mobile sleeve pipe through spiral sleeve，Gag lever post is placed on main body rack，Stop collar is placed on gag lever post，And by connecting rod with mobile telescopic joint，Sample placing device is by moving curved baffle、The fixing arm of force、Threaded sleeve、Determine curved baffle、Adjusting knob、Threaded rod and sampling steel cylinder composition，Determine curved baffle to be placed on the bottom of main body rack，The fixing arm of force is placed on the bottom of main body rack，Threaded sleeve is placed on the fixing arm of force，Dynamic curved baffle is placed in determines curved baffle side，And and threaded rod one end connection，The other end of threaded rod connects through threaded sleeve and adjusting knob，Sampling steel cylinder is placed in be determined between curved baffle and dynamic curved baffle，And be positioned at immediately below pressing plate.
During use, first being placed on by graduated for outer wall belt transparent sampling steel cylinder determines between curved baffle and dynamic curved baffle, size according to sampling cylinder diameter, rotate adjusting knob, threaded rod is driven to rotate in threaded sleeve, make curved baffle and determine curved baffle, stuck fast sampling steel cylinder, the natural soil sample that cutting ring is taken, it is positioned in sampling steel cylinder uniformly, described dynamic curved baffle and the design determining curved baffle, it is possible to disposable placement is tested closely knit soil and produced required soil sample, it is not necessary to additionally add soil sample.Motor rotates, drive line shaft rotates, and line shaft drives spiral guide rod to rotate, and the spiral sleeve on spiral guide rod moves down, spiral sleeve drives moving sleeve to move down, mobile sleeve pipe is moved downward by depression bar band dynamic pressure plate, and pressing plate constantly presses down curved baffle and the soil sample determined between curved baffle, soil sample is compacted in sampling steel cylinder, the design of described overflow-prevention cover plate, it is prevented from soil sample in pressing process, overflows in a large number above pressing plate, affect producing of closely knit soil.The design of described stop collar, it is possible to prevent moving sleeve in the process moved up and down, be subjected to displacement.Reach to be effectively improved closely knit soil sample and originally produce the purpose of efficiency.
