Description
Technical field:
The utility model relates to the building engineering construction fields of measurement, particularly relates to a kind of vertical survey device.
Technical background:
In the building engineering field construction survey, often need utilize the reference plane absolute altitude, measure the absolute altitude on a certain plane.The most frequently used method is at present, utilizes spirit-leveling instrument, Sopwith staff to measure the discrepancy in elevation of tested plane and reference plane, calculates reference plane absolute altitude and this discrepancy in elevation algebraic sum then, obtains the absolute altitude on measured plane.
The method of this measurement discrepancy in elevation is pretty troublesome, need set up spirit-leveling instrument and carry out also needing to carry out the accurate adjustment level after coarse adjustment is put down, also need be at reference point and the upright respectively Sopwith staff of measured point, if when between spirit-leveling instrument and reference point or spirit-leveling instrument and measured point, having the barrier of block vision, also need to set up in addition Sopwith staff, by repeatedly leading survey,, just can obtain the absolute altitude on tested plane to get around barrier.This method has a lot of shortcomings: spirit-leveling instrument belongs to exact instrument, needs specialized agency that it is regularly checked, to guarantee the degree of accuracy of its measurement; Spirit-leveling instrument install and leveling cumbersome, in case leveling is accurate inadequately, will there be very mistake in measurement result; No matter be installing of spirit-leveling instrument or setting up of Sopwith staff, all need certain workplace and space, can't operate if the workplace on measured plane and space are too small; Measuring process needs two people to cooperate at least, has wasted artificial; When running into the barrier that influences sight line, need repeatedly lead survey, not only work efficiency descends, and is easy to produce operate miss, makes error strengthen.
The utility model content:
The purpose of this utility model is the deficiency at existing vertical survey device and measuring method, a kind of vertical survey device and measuring method thereof are provided, not only can be so that surveying work is simple and easy to do, and can save the working time and artificial, need repeatedly lead the trouble of survey in the time of can also avoiding existing measurement mechanism and method to run into barrier.
A kind of vertical survey device and measuring method thereof that the utility model provides, the vertical survey device is made up of two cylindrical shell and the flexible pipes that can observe an interior liquid level, it is characterized in that: have scale on the cylindrical shell, can indicate the liquid level in the cylindrical shell, two cylindrical shells are equipped with colored liquid by soft pipe connection in the cylindrical shell.
The cylindrical shell outside has casing; cylindrical shell is shielded; casing and cylindrical shell sealing are installed; make liquid can not flow into the interlayer of casing and cylindrical shell; the casing below is equipped with base; can make stable being placed on a certain plane of the utility model, the casing sidepiece has window, can observe the liquid level of colored liquid in scale on the cylindrical shell and the cylindrical shell by window.
When two cylindrical shells were in same surface level, liquid level position can make the scope of measuring the discrepancy in elevation reach maximum near these volume 1/2nd places in the tube.The length of flexible pipe can intercept arbitrarily as required.
The casing upper end has bleeder vent, the casing top seals with cover, also have on the cover with casing on the corresponding bleeder vent in bleeder vent position, in the time of the sealing casing, turn cover, make the bleeder vent on cover and the casing produce displacement, with bleeder vent also sealing together, to prevent that colored liquid flows out in the moving process; When using, turn cover, the bleeder vent position on cover and the casing is overlapped, a feasible tube inner and outer air pressure unanimity can be measured.
Principle of work of the present utility model is: utilize law of connected vessels, place a cylindrical shell respectively at reference plane and measured plane, barrel wall is marked with scale, cylindrical shell links to each other by flexible pipe, make two cylindrical shells become a linker, in the tube colored liquid is housed, by the reading of liquid level position in two tubes, calculate its difference, can draw the discrepancy in elevation of measured plane and reference plane.
Measuring method of the present utility model is finished like this:
1) one of them cylindrical shell is placed on reference plane, another cylindrical shell is placed on measured plane, turn the cover on tube top respectively, cover is overlapped with bleeder vent position between barrel, guarantee that an internal gas pressure is identical with ambient pressure;
2) adjust flexible pipe, make flexible pipe not folding, can begin to measure;
3) treat in two cylindrical shells behind the liquid level stabilizing that deduct the liquid level reading of measured plane upper shell with the liquid level reading of reference plane upper shell, the gained difference is the discrepancy in elevation of measured plane and reference plane; Under the up big and down small situation of scale,, show that measured plane is higher than reference plane if difference is a positive number; If difference is a negative, show that measured plane is lower than reference plane.
The utility model operating process is easy, only needs a people to operate, and has saved one at least manually than existing measuring method; Can get around any barrier, very low to workplace and space requirement, high efficiency after what a cylindrical shell reference plane places, can be measured the discrepancy in elevation (discrepancy in elevation of this plane and reference plane is not more than a scale maximum magnitude on the cylindrical shell) of any one plane and reference plane at any time; And measurement result is accurate, when there is visual barrier the centre, also can finish by one-shot measurement.

Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
By Fig. 1-3 as can be known, before the measurement, at first, the coupling sleeve 7 at flexible pipe 9 two ends is screwed in respectively on the connected entrance 6 of two cylindrical shell 3 lower ends, makes the sealing gasket 11 in flexible pipe 9 terminations tightly withstand connected entrance 6 terminations, guarantee that connected entrance 6 and flexible pipe 9 are tightly connected; Then, the utility model is placed same plane, turn on cover 1, colored liquid 5 is injected in the cylindrical shell 3, when liquid level reaches cylindrical shell 3 wall scale readings 4 half left and right sides, can tighten cover 1, in order to avoid colored liquid spills in the device moving process; Again one of them cylindrical shell 3 is positioned on the reference plane 12, make base 8 sit reposefully, then another cylindrical shell 3 is positioned on the measured plane 13, make its base 8 sit reposefully, unscrew cover 1 then, cover 1 is communicated with bleeder vent 10 between barrel, guarantee that the tube internal gas pressure is identical with ambient pressure; After treating two cylindrical shells, 3 interior liquid level stabilizings, deduct the liquid level reading of measured plane 13 upper glass tubes 3 with the liquid level reading of reference plane 12 upper glass tubes 3, the gained difference is the discrepancy in elevation of measured plane 13 and reference plane 12, if difference is a positive number, show that measured plane 13 is higher than reference plane 12; If difference is a negative, show that measured plane 13 is lower than reference plane 12.The cylindrical shell 3 outer casings 2 that are provided with, its effect is a protection cylindrical shell 3.
