Under normal circumstances, space is small in pipeline tunnel, only supplies a people or two people to pass through substantially, is digging tunnel process
In, one section of the distance often excavated just needs to carry out elevation carrection to punctuate to control the cutting of tunnel.Currently, ordinary circumstance
Under, the not high punctuate measurement of higher degree of height is all to be measured using measuring scale or tape measure, but this measurement accuracy is relatively low, may
There are larger errors, and large effect can be all generated to the working procedure of grouting, the lining cutting of later stage tunnel.
Invention content
Technical problem to be solved in the utility model is device for measuring elevation in a kind of pipeline tunnel, can be more accurate
Absolute altitude in pipeline tunnel is accurately measured, reduce caused by measurement error is construction in later period influence.
In order to solve the above technical problems, technical solution used by the utility model is：Absolute altitude is surveyed in a kind of pipeline tunnel
Device, including main measuring rod are measured, main measuring rod is equipped with the mounting groove being arranged along main measuring rod length direction, is equipped in mounting groove
Graduated scale, main measuring rod lower end are equipped with lower cylinder, and upper end is equipped with upper cylinder, and upper cylinder is tubular construction, and upper cylinder inner wall is equipped with internal thread, main
Measuring rod top is equipped with the external screw thread with upper cylinder screw-internal thread fit.
In preferred scheme, the upper cylinder and lower cylinder are equipped with positioning conehead, and the tapering for positioning conehead deviates from main measuring rod
Setting.
In further embodiment, the upper cylinder and lower cylinder are connected through a screw thread with positioning conehead.
In further embodiment, the positioning conehead material is cast iron.
In preferred scheme, the lower cylinder is tubular construction, and lower cylinder inner wall is equipped with internal thread, main measuring rod lower part be equipped with
The external screw thread of lower cylinder screw-internal thread fit.
In preferred scheme, it is equipped with supporting block on the outside of the lower cylinder, cylindrical support slot, support slot bottom are equipped in supporting block
Portion is vertical with main measuring rod, and circular bubble is equipped in support slot.
In preferred scheme, the graduated scale slides up and down in mounting groove.
Device for measuring elevation in a kind of pipeline tunnel provided by the utility model makes entirely to fill by turning upper cylinder up and down
The height set changes, and by measuring absolute altitude in pipeline tunnel in the position of graduated scale on the downside of lower cylinder, it is accurate to measure, operation
Simply.The positioning conehead of setting is conducive to the positioning up and down of whole device, also, it helps in whole device measurement process
Stability.Upper cylinder and lower cylinder are connected through a screw thread with positioning conehead, convenient to be replaced when locating cone hair gives birth to abrasion, are prevented
Only because of measurement error caused by abrasion.The circular bubble of setting can ensure that entire measuring device is in vertical state, prevent
Because artificially observe cause device tilt due to caused by measurement error.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
Fig. 3 is Fig. 2 along the faces A-A sectional view.
In figure：Main measuring rod 1, mounting groove 2, graduated scale 3, lower cylinder 4, upper cylinder 5, positioning conehead 6, supporting block 7, support slot 8,
