Description
Technical field
The utility model relates to level measurement chi at the bottom of a kind of aperture, belongs to field of measuring technique.
Background technology
In project elevation is measured, majority is the absolute altitude of measurement plane or extrusion position, and it is less for the measuring method of aperture elevation of bottom, rod member directly gos deep into making marks on rod member after bottom aperture by usual employing, measure rod member top again to mark position length, such measuring method is comparatively rough, precision is low, and measure more aperture elevation of bottom time complex operation, efficiency is lower.
Summary of the invention
The utility model provides level measurement chi at the bottom of a kind of aperture, and for the existing metering system complex operation of solution, efficiency is lower waits deficiency.
The technical solution of the utility model is: level measurement chi at the bottom of a kind of aperture, comprises main elevation ruler screw rod 1, elevation ruler scale 3, main elevation ruler 4, secondary elevation ruler 5, screw slot 6, bottom bar screw rod 7, bottom bar 8; Wherein bottom bar 8 screws in the screw slot 6 of main elevation ruler 4 by bottom bar screw rod 7, and secondary elevation ruler 5 screws in main elevation ruler screw rod 1, and main elevation ruler 4, secondary elevation ruler 5 are respectively equipped with elevation ruler scale 3; Described bottom bar 8 selects taper bottom bar 8-1 or needle-like bottom bar 8-2 according to aperture form.
Described main elevation ruler is provided with leveling bubble 2.
Described main elevation ruler 4 and secondary elevation ruler 5 are cylindrical rod piece.
Principle of work of the present utility model is:
Select taper bottom bar 8-1 or needle-like bottom bar 8-2 to screw in the screw slot 6 of main elevation ruler 4 by bottom bar screw rod 7 according to aperture form, then according to observation needs, use secondary elevation ruler 5 to screw in main elevation ruler screw rod 1.Elevation ruler scale 3 counts 0mm scale by taper bottom bar 8 or needle-like bottom bar bottom, because the aperture measuring degree of depth is limited, so bottom bar length adds that main elevation ruler 4 and secondary elevation ruler 5 length sum are 2.0m, can meet user demand.
After completing the assembling of aperture measuring chi, taper bottom bar 8-1 or needle-like bottom bar 8-2 is deep into bottom aperture to be measured, guarantee no-sundries impact contact bottom aperture, then main elevation ruler 4 is adjusted all around, until the bubble in leveling bubble 2 is placed in the middle, show that elevation ruler is vertical with aperture base plane, at this moment just can be spent reading accurately by master of ceremonies person's observation.
The beneficial effects of the utility model are:
1, than the method for converting absolute altitude after the degree of depth of employing tolerance in the past, measurement of the level progress and measuring speed have very large lifting.
2, when adopting column type dip stick to avoid absolute altitude at the bottom of measured hole, dip stick shape and hole shape do not meet and cannot go deep into, be set to needle-like bottom dip stick is exactly do not affected by bottom foreign material to measure aperture bottom position more accurately simultaneously, it is verticality in order to ensure dip stick that the main body of dip stick is installed leveling bubble, guarantee that dip stick does not affect the precision of measurement because of inclination, coordinate master of ceremonies person to complete the number of degrees together to measure, just can accurately obtain aperture elevation of bottom, use the utility model greatly can improve efficiency and the accuracy of the measurement of aperture elevation of bottom in a word.
