Abstract
The utility model provides a water sac type volume measuring instrument, which is mainly composed of a water sac, a cylinder, a piston, a hollow piston rod, a handle and an exhaust valve, wherein the upper port of the cylinder is provided with a vernier, the lower part of the cylinder is fixedly connected with a bottom board, the lower end of the hollow piston rod is communicated with the water sac, a water level mark and a scale mark are arranged on the rod body, and a partition sheet which is provided with holes can be arranged on the upper part of the water sac. The utility model has the advantages of simple structure, accurate measurement, effective protection of the water sac, convenient work and transport, simple operation and convenient use.
Description
The utility model relates to a kind of geotechnological instrument, especially relates to a kind of surveying instrument that utilizes the water bag method can measure the volume of testing pits.
When engineerings such as railway, highway, airport are measured filling compaction density or porosity, often need to measure the volume of testing pits, the water bag measuring method is a method preferably.At present, need be furnished with air pump on the water bag analyzer of the U.S., need inflate and bleed during use, operate more loaded down with trivial details; During reading, because of the water temperature variation, volume determination needs could guarantee that through demarcating measurement numerical value is accurate, bothers during use.The water bag analyzer of Germany has saved air pump, but because when not using, water pocket always shows especially brokenly in the cylinder barrel bottom, so when using, need dig a shallow hole earlier, measure initial reading after, continue again to dig to test pits, after arriving standard depth, measure the termination reading again, operation steps is also more loaded down with trivial details, and when not using, water pocket easily is extruded, breakage, inconvenience transportation and work carrying.
The purpose of this utility model is to provide a kind of water-bag type volume determination instrument at above-mentioned the deficiencies in the prior art, have simple in structure, easy to use, be convenient to transportation, measure combination properties such as accurate.
Above-mentioned purpose of the present utility model is achieved by the following technical solution: a kind of water-bag type volume determination instrument, and it comprises: water pocket, cylinder barrel, base plate, piston, hollow piston bar, handle and vent valve; Described water pocket is arranged on the bottom of cylinder barrel; The lower end of described hollow piston bar communicates with water pocket; Described cylinder barrel upper port is provided with vernier, and cylinder barrel bottom and base plate are affixed; Described hollow piston bar is provided with water-line target and scale mark.
In the such scheme, between cylinder barrel bottom and water pocket, be provided with spacer with holes.
During use, analyzer of the present utility model is placed on the ground of leveling, open vent valve, promote piston downwards, the liquid level in the hollow piston bar rises to water-line target, reads piston initial alignment reading (L
0); Mention piston, analyzer is moved apart this ground; Test pits dig after, analyzer is placed original position again, after fixing, promote piston downwards, when liquid level rises to water-line target once more, read piston and stop positional readings (L
1).
Analyzer of the present utility model has the following advantages compared with prior art:
1, simple in structure, measure accurately; The air pump of configuration inflation in addition, the usefulness of bleeding does not make to simplify the structure easy operating.Measure and adopt the numerical difference between that stops reading and initial reading, be not subjected to the influence of water temperature, measuring accurately and not needs frequent demarcation.
2, water pocket is subjected to effective protection, is convenient to transportation and work carrying; Because the setting of elastomeric isolation sheet, in the test interval, water pocket can tightly be adsorbed under the spacer; and do not enter in the cylinder barrel, also can show especially regularly in the cylinder barrel bottom, water pocket is not squeezed; not easy to wear, can be subjected to effective protection, be convenient to work displacement, carrying and remote transportation.
3, simple to operate, easy to use; Because water pocket does not show especially in the cylinder barrel outside, when measuring initial reading, do not need to dig earlier a shallow hole.When using this analyzer, operation steps can be simplified, and is easy to use.
Below in conjunction with drawings and Examples, further specify the utility model.
Fig. 1 is the structural representation of water-bag type volume determination instrument.
Fig. 1 illustrates the structure of the water-bag type volume determination instrument in the use.With reference to Fig. 1, analyzer of the present utility model mainly is made up of water pocket 1, base plate 10, spacer 2, piston 3, cylinder barrel 4, handle 5, hollow piston bar 6 and vent valve 7.Water pocket 1 sealing is arranged on the bottom of cylinder barrel 4; The lower end of hollow piston bar 6 communicates with water pocket 1, and vent valve 7 is installed in the upper end, and the body of rod is provided with water-line target 61 and millimeter scale mark 62; Cylinder barrel 4 upper port are provided with vernier 8, and cylinder barrel 4 bottoms and base plate 10 are affixed.Between the bottom of cylinder barrel 4 and water pocket 1, be provided with holes 21 spacer 2, when design is intended to not use this analyzer like this, upwards spur handle 5, make the water 9 in the water pocket enter cylinder barrel 4 by hole 21, and water pocket 1 tightly is adsorbed on the spacer 2, does not enter in the cylinder barrel 4.
Because the setting of elastomeric isolation sheet 2, make water pocket not be inhaled into cylinder barrel 4, and can be adsorbed on spacer 2 bottoms, make water pocket can show especially regularly outside cylinder barrel 4, cause the difficulty of work carrying, remote transportation, also can not cause and not dig a shallow hole earlier when measuring, put into water pocket, measure the inconvenience of initial value, be convenient to operation, be convenient to transportation.
During use, annex is protected hole steel loop 12 place on the ground of leveling; This measuring instrument placed protect on the steel loop 12 of hole, and with fastening bolt 11 that base plate 10 is fixing, with piston 3 lifting certain altitudes, water pocket 1 is not squeezed; Open vent valve 7, slowly promote piston 3 downwards, the liquid level in hollow piston bar 6 rises to water-line target 61 places, reads piston initial alignment reading (L
0), at this moment, can on ground level, read initial number, also can dig shallow hole and read initial number.Mention piston 3, with this analyzer move apart protect the hole steel loop 12, test pits dig after, this analyzer reapposed protect on the steel loop 12 of hole, and fixing, slowly promote piston 3 as stated above downwards, when liquid level rises to water-line target once more, read piston and stop positional readings (L
1), utilizing the difference that stops reading and initial reading, the substitution formula can be measured the volume size of testing pits.
