Description
Technical field
The present invention relates in construction, a kind of vertical survey utilizing law of connected vessels to work and gradient measuring device.
Background technology
In fields such as project building construction, it is often necessary to the difference in height between measuring at 2 and the angle of gradient.Building is executed at present
Between the measurement 2 that industrial and commercial bank's industry is more common, height distribution method is summarized as follows:
(1) flexible pipe " water detection is put down " method builder uses the transparent hose of a dress water, and flexible pipe one end is upright with a certain
Place to be measured, is dragged to other position, the then liquid level position of labelling two flexible pipe by the other end of flexible pipe, here it is described " water detection
Flat ".After finding level, raised or reduction flag line by the method for line again according to highly desirable, so that it is determined that relative elevation.
" water detection is put down " utilizes law of connected vessels to work, it is desirable to whole inside hose is not allow for bubble；If in flexible pipe
There is bubble, then measurement result will appear from deviation, and maximum measured deviation is equal to the vertical height of bubble.But, the use of workman
Custom is always existing with now pouring water, and owing to the internal diameter of flexible pipe is typically small, easily retains bubble in managing, make when pouring water in flexible pipe
Measurement result compares with actual value has a greatly reduced quality.
So, determine that the method for absolute altitude has simple, the cheap and convenient feature of measuring instrument with " water detection is put down ", but it causes
Life defect is that measurement is inaccurate, can not directly determine absolute altitude.Therefore, the method is only limitted to the Simple engineering that dimensional requirement is the highest
Construction.
(2) laser leveler method laser leveler is a kind of measuring instrument occurred in recent years, and it is widely used in building
Build construction and decorative engineering.Laser leveler is to utilize the low emission of laser and plumb line principle (direction of gravity is always erected
Straight downward) work, its certainty of measurement is decided by inner laser pipe and the angle of plumb line and the horizontal range of measured object.
Inner laser pipe is determined when producing with the angle of plumb line, requires that the angle of the two must be 90 degree in theory, when dispatching from the factory
Will be through strict debugging；The horizontal range of measured object is the biggest, and horizontal error is the biggest, when horizontal range is more than 20 meters
Time, the width of laser scanning line has reached 5-10 millimeter, and this is the biggest on measurement result impact；Inner laser pipe and plumb line
Angle there will be small change along with factors such as the prolongation of service life, ambient temperatures, and this minor variations is to measurement result
Impact be the hugest.
Therefore, laser leveler method is also a kind of simple and that precision is low method.Strict construction field is required at some
Conjunction cannot use.
(3) level gauge method level gauge is that a kind of horizontal line of sight of setting up measures the instrument of the ground point-to-point transmission discrepancy in elevation.Main portion
Part has telescope, pipe spirit level (or compensator), vertical axis, pedestal, foot screw.It is divided into tilting level by structure, is automatically pacified
Flat level gauge, laser level and digital level (also known as electronic level).It is divided into precision level and light water by precision
Quasi-instrument.
Level gauge is applicable to the instrument of the measurement of the level, and current China level gauge is that the every km that can reach by instrument comes and goes
Survey what this precision index of accident mean square error of number in the discrepancy in elevation divided, be divided into 4 grades, DS05, DS1, DS3 and DS10,1
Km come and go in the discrepancy in elevation number accident mean square errors be respectively≤0.5mm ,≤1mm ,≤3mm ,≤10mm.
Level gauge is a kind of precision and valuable measuring instrument, is widely used in the industries such as mapping, construction at present, it
It it is the instrument of surveying and mapping of a kind of higher gears.Operation and use level gauge need professional and technical personnel and carry out.
Although level gauge has higher certainty of measurement, bigger measurement distance, but its measuring condition is affected by weather, and
And can not across obstacle, must be that straight line is visible between reference position and measured position.
Though level gauge is good, but it it not the top-grade instrument that everybody can have, everybody can use.Some unskilled labourers on the ground, past
Toward being not used.
To sum up, in currently known vertical survey instrument, if requiring in high precision, on a large scale, to be necessary for using DS05
Or more than DS1 high-precision level (precision is that in every kilometer round trip, error is 0.5-1mm, ordinary level be every kilometer past
Returning middle error is 3-10mm)；In less demanding measurement occasion, can use ordinary level, laser leveler or flexible pipe even
Logical device, its accuracy rating is 10-30mm.
What the present invention proposed is a kind of based on law of connected vessels, has both had degree of precision (no more than 1mm), easy to use,
And vertical survey instrument cheap, multi-functional.
Vertical survey instrument based on law of connected vessels, we retrieve three pertinent literatures:
Document (one) CN01209421-statoscope (2001) utility model patent, law of connected vessels, use different tube diameters
Water tank and connecting tube, by calculate or precomputation demarcate the discrepancy in elevation.Require connecting tube uniform diameter and non-expansion；Measure

Detailed description of the invention:
One, install and prepare
Each parts are attached installing according to the structural feature of the present invention.After checking air-tightness, open and adjust end flow velocity tune
Joint valve 6 and measurement end flow rate regulating valve 9；Open tank seal lid 4, inject through hyperchromatic pure water in cubic water tank 1, make
The initial position of liquid level is higher than 0 degree of groove of angle graduated scale 5 less than " 00 " graduation mark of discrepancy in elevation rule 11；Close water
Case seals lid 4.
Two, adjust
1. standpipe flow velocity balanced adjustment closes drum airbag valve 13, constantly blasts in cubic water tank 1 with air-blowing capsule 3
Air, makes the plenum interior pressure of more than cubic water tank 1 internal liquid level increase, and cubic water tank 1 internal liquid level be can be observed and decline,
Adjust the transparent standpipe of end 7 and measure the rising of end transparent standpipe 10 internal liquid level.Open the bulging airbag valve 13 having on air-blowing capsule 3
Time, the flow direction of liquid level is contrary.A period of time after stopping heaving and exitting, adjust the transparent standpipe of end 7 and measurement end is transparent vertical
Pipe 10 internal liquid level can be the most equal.
Air-blowing and venting repeatedly, observes and adjusts the transparent standpipe of end 7 and measure the change speed of end transparent standpipe 10 internal liquid level
Degree, regulation adjusts end flow rate regulating valve 6 and measures the open degree of 9 two valves of end flow rate regulating valve, until two riser interiors liquid
Till the pace of change in face is basically identical.
Standpipe flow velocity balanced adjustment is to save the measurement time to reduce the level balance time.If do not adjusted
Whole, do not affect certainty of measurement, simply the balance waiting time can be the longest.
2. vertical survey adjusts and adjustment end and measurement end is placed on same horizontal plane；Close drum airbag valve 13,
In cubic water tank 1, blast air lightly with air-blowing capsule 3 or release air, making to swim in measurement end transparent standpipe 10 internal auxiliary
The bottom surface of float 2 16 is helped to align with " 00 " line of discrepancy in elevation rule 11；Keeping liquid level position motionless, it is saturating that regulation is enclosed within adjustment end
The position of the liquid level marker loop 8 on bright standpipe 7, the groove making liquid level marker loop 8 maintains an equal level with the bottom surface helping float 1.Adjust
Finish.
Three, use
1. the end of measuring of the measuring instrument after vertical survey will be adjusted moves to position to be measured, by air-blowing or put
Gas, adjusts the liquid level position within the transparent standpipe of end 7, makes the bottom of auxiliary float 1 and the liquid fixed when adjusting
The groove of bit flag ring 8 maintains an equal level, and makes the liquid level within the transparent standpipe of adjustment end 7 come back to position when adjusting.
At this moment, the discrepancy in elevation can directly be read on the discrepancy in elevation rule 11 measuring end.If that measures end helps float 2 16
Bottom surface is less than " 00 " groove, illustrate measured position higher than reference position, reading be "+"；If that measures end helps float 2 16
Bottom surface is higher than " 00 " groove, illustrates that measured position is less than reference position, and reading is "-".All with auxiliary float 2 16 during reading
Bottom be as the criterion.Certainty of measurement is determined by the graduating accuracy of rule, can be as accurate as 0.5-1 millimeter.
The scientific basis of vertical survey: according to law of connected vessels, no matter air chamber pressure is much, adjusts the transparent standpipe of end
7 with measurement end transparent standpipe 10 internal liquid level the most in the same plane.Owing to making the liquid level of two pipes at the discrepancy in elevation scale when adjusting
On " 00 " groove of chi 11, make the liquid level of two standpipes return to original position further through adjustment air chamber pressure during measurement, therefore survey
Height change h1 of amount end is necessarily equal to measuring the change h2, i.e. h1=h2. of end transparent standpipe 10 internal liquid level it is to say, survey
Amount end is elevated how many end transparent standpipe 10 internal liquid level of measuring and just declines how many, and vice versa.
As for the auxiliary float 1 in two standpipes and auxiliary float 2 16, clearly and easily read merely with its bottom boundary
Number.Because the size shape of two floats is consistent with material, so the bottom of two floats is also identical to the discrepancy in elevation of corresponding liquid level
, and be also adopted by identical position when adjusting before measuring and carry out labelling 0 height, therefore the existence of float does not affect the measurement of the discrepancy in elevation.
2. slope measuring
By adjust end move to be measured domatic on, by the method for air-blowing or venting adjust that transparent material makes square
Liquid level within water tank 1, make metal line within water tank by the center of angle graduated scale 5 "+"；When liquid level stabilizing,
Directly reading the groove number of degrees overlapped with liquid level from angle graduated scale 5 is exactly the tested gradient.
The scientific basis of slope measuring: during fabrication, 0 degree of groove of angle graduated scale 5 is strict with the bottom of cubic water tank 1
Parallel；Water tank regular shape and symmetrical；The center of angle graduated scale 5 "+" on the symmetrical line of water tank.
When water tank is placed in the horizontal plane, 0 degree of groove of angle graduated scale 5 is certain and plane-parallel；Adjust liquid
Face height, necessarily can make 0 degree of groove of angle graduated scale 5 overlap with water tank internal liquid level.
When water tank be placed on domatic upper time, water tank level still with plane-parallel, if now adjust liquid level make
Metal line within water tank by the center of angle graduated scale 5 "+", then the folder between liquid level and 0 degree of groove of angle graduated scale 5
Angle is necessarily equal to domatic slope number.
Four, the present invention and the advantage synopsis of known products
As can be seen here, this invention the most relatively, has the advantages that precision is high, easy to use, cheap,
Be conducive to being widely popularized.
Need not change additionally, due to the water in storage tank of the present invention and pipeline, as long as it is pure disposably to inject appropriate dyeing
Water, there is not the problem polluted by hard water, can keep lasting transparency in the most transparent pipeline and water tank.Additionally, it is U-shaped
Water in pipe is with pressure-feed from water tank bottom, the problem that there is bubble in there is not U-tube.Thus avoid simple U
