The measuring method of above-mentioned push pipe intelligence jacking measuring system, in measuring instrument initial position and using forward sight rib
Manual measurement is used when mirror is rectified a deviation, remaining data feedback to industrial computer for all being obtained by apparatus measures is processed, right
Tool heads are rectified a deviation in real time, and measuring method is simple, and certainty of measurement is high.
The corresponding relation of center line tracking and jacking distance is the basis of whole measurement, for convenience of daily simplified calculating, is adopted
With " with straight Dai Qu " thinking --- (such as 3 meters or per tube coupling length) are expressed as point string in order to center line at a certain distance, jacking away from
From corresponding with plane coordinates, elevation, center line is expressed as：L (jacking distance, centre coordinate, i=1,2,3 ..., n)；
If the point centered on point P (jacking distance) on line between k and k+1, there are the P point coordinates computing formula to be：
Daily footman's measurement is spaced regular automatic measurement by setting time, if therefore often section pipeline section forward sight prism point is measured
Dry time, these coordinates will be fitted to the point that measure of learning forms center line tracking.
With (xi yi)T(i=1,2 ..., n) represent the n coordinate of point, based on the thinking of small segment limit " with straight Dai Qu ",
If these points meet linear equation 2-1：
In formula,
(xp yp)TTo leave the coordinate of origin closest approach on straight line；
T is distance of the p points to arbitrfary point on straight line.
Cross and measure point (xi yi)TThe coordinate of arbitrfary point meets 2-2 on the straight line vertical with fitting a straight line：
D is arbitrfary point (x y) on vertical line in formulaTWith (xi yi)TThe distance between.
Vertical line meets linear equation 2-1 and 2-2 with the intersection point of fitting a straight line,
By above formula, solve：
D=a (yp-xi)-b(xp-yi)
Above formula is exactly apart from v to straight lineiFor：
vi=a (yp-xi)-b(xp-yi)
Parameter in above formula is a, b, xp、yp, totally 4 parameters.
Take two constraintss into account, condition one is (a b)TIt is unit vector, i.e.,：
Second conditional defines (xp yp)TIt is point nearest from origin on straight line, i.e. origin to (xp yp)TDirection with
Rectilinear direction is vertical：
Determine linear equation by with proviso error compensation method adjustment.
According to the coordinate at the line mileage of design centre, its intersection point for arriving fitting a straight line, the as seat of pipeline section center are calculated
Mark.
According to live physical condition, the scope such as rearscope, total powerstation, forward sight prism is arranged on push pipe cross section geometric
Center is unpractical, typically be can be only installed on push pipe wall, it is therefore desirable to mileage and center at the push pipe according to where equipment
Line coordinates obtains scope rearscope, total powerstation, the actual coordinate of forward sight prism, and then carries out measurement below.
During jacking, the push pipe section where the installation equipment such as rearscope, total powerstation, forward sight prism can deposit
Rotation situation, rotation on be calculated rearscope, total powerstation, forward sight prism actual coordinate be it is influential, because
This is about relative on the same section of equipment such as rearscope, total powerstation, forward sight prism for section anglec of rotation ɑ where obtaining
An auxiliary prism is installed in position, the discrepancy in elevation of periodic observation rearscope, total powerstation, forward sight prism and corresponding auxiliary prism, from
And it is calculated section anglec of rotation ɑ.
By taking rearscope Pb as an example, calculated to simplify, push pipe section where Pb is circular section.Equipment installation first
Afterwards, actual measurement artificial first obtains Pb points, auxiliary magnet Pb ' and section center lPb three-dimensional coordinates, can obtain initial by calculating
Cross sectional radii and Pb-lPb, Pb-Pb ' line azimuth during state, it is determined that carrying out the first of tube wall Coordinate Conversion according to centre coordinate
Beginning parameter.Follow-up periodic measurement Pb points and Pb ' discrepancy in elevation, Pb-Pb ' line sides at current section can be calculated according to discrepancy in elevation change
Parallactic angle, the anglec of rotation ɑ for obtaining current section is compared with initial orientation angle, and then obtains Pb-lPb lines azimuth, by known
Cross sectional radii can determine the parameter of current section Coordinate Conversion, so as to realize pipeline section centre coordinate to total powerstation, lens seat
Target is changed.
Embodiment one
In order to be able to evaluate the precision of intelligent jacking measuring system, we are compared using the method for manual measurement.System
It is initially applied to the long distance curved pipe jacking internal diameter of the pipeline that Changzhou riverside sewage treatment plant pipe network extension project two marks W8-W7 wells
It is 2.2m, push pipe length 764m.System is using 1 total powerstation and 5 prism compositions, radius of curvature 800m.
1) horizontal control survey：Using two horizontal control points Z1, Z2 providing, will by national fourth class wire measurement techniques
The plane coordinates of (survey time of angle measurement 4, round 2 survey time find range) translocation active well instrument platform (T) and neighbouring orientation point (A) is sought, as
The plane Fixed Initial Point of subsequent artefacts' shaft centerline measurement.
2) push pipe center line plane measurement：Set from T and stood firm to A points, open traverse Automatic survey equipment installation region is (about
Push pipe centre coordinate 100m).The survey time of angle measurement 4, distance comes and goes the measurement of 2 survey time.In on December 24th, 2015, December 25 in 2015
Three measurements are carried out day, on December 27th, 2015.
3) the push pipe center line measurement of higher degree：Due to in-site measurement time restriction, elevation is directly surveyed using the survey time of triangulated height 4
The amount discrepancy in elevation, and synchronously carried out during plane survey, providing elevation by retainer instrument platform T is started at.
Intelligent jacking measuring system marks W8-W7 well Curve Pipe Jackings in Changzhou riverside sewage treatment plant pipe network extension project two
In carry out the contrast of 3 manual measurements altogether, as can be seen that the middle error of intelligent jacking measurement and manual measurement will not be with from contrast
The increase of distance and increase.
Plane：On December 24th, 2015, on December 25th, 2015, on December 27th, 2015 have carried out the measurement of three fold axis line,
Fig. 1 is shown in axis point measurement comprising active well interior orientation measurement error.
For statistical error is distributed, center line scatterplot data were measured in CAD lines with December 24th, 2015, by three overlaps
On December 25th, 2015 in region, the scatterplot on December 27th, 2015 do vertical line to the line of on December 24th, 2015, statistics hang down away from
Such as table 1 below.
Table 1
The error of active well orientation survey is deducted, shaft centerline measurement uniformity (includes axis actual deviation and polar coordinate measurement
Error) preferably (data level is in 1cm).
The error of indivedual elevational point measurements is rejected, axis elevation trend is basically identical.
It follows that the certainty of measurement of intelligent jacking measuring system is consistent with the precision of manual measurement, survey
Amount data are same reliable.Because intelligent jacking measurement pointing accuracy in push pipe pipeline is high, measuring speed is fast, certainty of measurement
Manual measurement is above, manual measurement measurement error repeatedly is in ± 1-2cm.
Obviously, those skilled in the art can carry out various changes to the utility model and deform without deviating from this practicality
New spirit and scope.So, if it is of the present utility model these modification and modification belong to the utility model claim and
Within the scope of its equivalent technologies, then the utility model is also intended to comprising these changes and modification.
