Abstract
The utility model relates to a volume measuring instrument, which is mainly characterized in that a graduated flask is connected with an air bag, the air bag is inwards collected in the graduated flask before measuring the volume of a test pit, at the time, the graduated flask is flatly placed on a base plate, a plurality of small holes are arranged on the base plate, the base plate is placed right above the test pit, then, a piston cover is inserted into an upper opening of the graduated flask, lead blocks with certain weight are contained in the piston cover, the piston cover naturally falls down to compress the air in the graduated flask until the balance is reached, the air bag wall can be extruded by air in the graduated flask to be tightly pasted on the periphery of the graduated flask wall because a plurality of small holes are arranged on the base plate, finally, the base plate is tightly pulled out, and the air bag wall is extruded to be tightly pasted on the periphery of the test pit wall for a second time by the piston cover. Because both the atmospheric pressure and the temperature are not changed in the measuring process, the volume in the graduated flask is not changed, the air in the graduated flask is not compressed even through the piston cover naturally falls down for a second time, and only the air in the graduated flask is extruded to the periphery of the test pit, so the downwards falling value of the piston cover is the volume of the test pit.
Description
Technical field
The utility model relates to a kind of be used to measure the specific volume measuring appratus that the Subgrade Compaction measuring point is tested pits, the especially measuring instrument that is combined by graduated cylinder and air bag.
Background technology
The packing test of construction of the highway scene detects adopts sand replacement method to go to replace the volume of testing pits mostly, and the shortcoming of this method is to carry more amount sand, and the weighing number of times is more, so its test speed is slower; The employing douche that has goes to replace the volume of testing pits, and exists the weighing number of times more equally, and test speed waits problem more slowly.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, the specific volume measuring appratus that can directly measure the volume of testing pits.
For addressing the above problem, design of the present utility model is: link to each other with an air bag with a graduated cylinder, tolerance is tested pits before the volume, closing in the air bag in the graduated cylinder, lie in graduated cylinder on one substrate this moment, substrate is provided with many apertures, directly over substrate is placed in and tests pits, next piston cap is inserted the graduated cylinder upper shed, comprise the lead of constant weight in the piston cap, allow piston cap fall to compressing the interior air of graduated cylinder naturally until balance, because of substrate is provided with many apertures, the air bag wall energy is close to around the graduated cylinder wall by air extrusion in the graduated cylinder, at last substrate is extracted out gently, and piston cap is close to airbag wall extruding around the wall of testing pits once more.Because of in the process of tolerance, atmospheric pressure, temperature all do not change, obviously the constancy of volume in the graduated cylinder, though piston cap falls once more naturally, do not compress the air in the graduated cylinder, just the air in the graduated cylinder press to test pits around, so the numerical value of piston cap whereabouts is exactly the volume of testing pits.Certainly in order to allow airbag wall extruding fully be close to around the wall of testing pits, air bag can be made of soft and the long-pending object plane material of air-locked nylon.
As optimization: described air bag is shaped as cylinder, diameter, the corresponding size of highly all testing pits greater than the survey cylinder when inflation; One circle sealing ring is arranged on the described piston cap face of cylinder.
Because of simple in structure, can directly measure the volume of testing pits, greatly reduce field work labour intensity, improved work efficiency and test accuracy.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Figure one is the utility model structure front elevation;
Figure two is the utility model structural upright view;
Figure three is the utility model metrics process synoptic diagram.
Embodiment
Specific volume measuring appratus shown in figure one, figure two, the figure three, this utility model is made up of graduated cylinder 1, air bag 2, piston cap 4, and piston cap 4 cylinders are provided with a circle O-ring seal 5, and graduated cylinder 1 end opening outer rim is provided with a circle positioning disk 3.Following at first substrate 6 being placed in of working routine tested pits directly over 7, closing in the graduated cylinder 1 in the air bag 2 and graduated cylinder 1 being lain on the substrate 6, next piston cap 4 is inserted in the graduated cylinder 1, allow piston cap 4 fall air in the compression graduated cylinder 1 naturally until balance, at last substrate 6 is extracted out gently, allow positioning disk 3 close proximity to grounds and the opening of testing pits around 7 sealed, piston cap 4 is close to the extruding of air bag 2 gas walls around the 7 hole walls of testing pits once more, so the numerical value that piston cap 4 falls is exactly the volume of testing pits.
Can directly measure the specific volume measuring appratus of the volume of testing pits has so just successfully realized.
