Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is the flow chart of racing track section precision online test method of the invention.
Specific embodiment
Core of the invention is to provide a kind of racing track section precision online test method, detects racing track in the construction process
The precision of concrete surface can find the error position poured in time, improve the construction efficiency and machining accuracy of racing track.
Fig. 1 is the flow chart of racing track section precision online test method of the invention, comprising the following steps:
S1, the section parameter that racing track concrete surface is obtained according to design drawing, obtain section theoretical diagram；Section theoretical diagram
It is the design section shape and size of racing track concrete surface, is the standard of racing track concreting, section theoretical diagram is racing track
Along the sectional view perpendicular to mileage direction, along racing track mileage direction, there is different section theoretical diagrams in different positions.
After S2, casting concrete, image total station is erected at racing track side, scans concrete table along racing track direction of advance
The axial section in face obtains section measured drawing；Racing track is spliced to form by Multi-section concrete component, and image total station is arranged in coagulation
On the axis direction of native component, axis is the mileage direction of racing track, and the section of image total station face racing track concrete component is swept
Retouch the shape of section.
S3, compare section measured drawing and section theoretical diagram, obtain the axial error everywhere of section measured drawing；Section measured drawing
It is annular plane structure with section theoretical diagram, is the actual measurement outer and theoretical outer of section part, by section measured drawing and section
Theoretical diagram fitting overlapping, the part of deviation within the error range are thought to meet design requirement, portion of the deviation beyond error range
Divide and think not meeting design requirement, needs to modify it, repeat the above process after finishing and measured again, until deviation
Until within the error range.
Racing track section precision online test method of the invention be applied to concreting process, measurement and comparison step and
Concreting carries out simultaneously, measures when not solidifying completely also after casting concrete, can find the error poured in time
Position, and correct in time, on-line checking is realized, the construction efficiency and machining accuracy of racing track are improved.Concreting process
Segmentation carries out, and often pours one section of progress one-shot measurement, and the spacing of rationally setting measurement detection guarantees the mixed of entire racing track as far as possible
Solidifying soil pours precision and meets design accuracy requirement.
Specifically, this method further includes the horizontal curve and vertical curve that racing track is obtained according to design drawing, obtains corresponding to flat
The section theoretical diagram of curve and each position of vertical curve.Horizontal curve HA, vertical curve VA and section theoretical diagram are extracted according to drawing, is put down
Curve HA is the projection of racing track in a horizontal plane, and vertical curve VA is projection of the racing track in vertical plane, horizontal curve HA and vertical curve VA
It is combined with section theoretical diagram, obtains the three dimensional space coordinate of the corresponding section of racing track, more accurately show section in space
Coordinate.
Specifically, the present invention is between mileage direction 2~2.5m of interval one section of detection, single section axial direction test point
Away from for 2~10cm；A section is chosen every 2~2.5m to be detected, and is a circular pattern for each section,
Multiple test points are chosen when detection, will test a little successively line formation cross-section diagram makes by reasonably setting the spacing of test point
Cross-section diagram reaches certain precision, and the density of test point is bigger, and obtained cross-section diagram is got over closer to truth, accuracy in detection
Height, with the high section measured drawing of accuracy compared with section theoretical diagram, obtained error result better authenticity.
The process for comparing section measured drawing and section theoretical diagram specifically includes, and section parameter input image total station leads to
It crosses image total station and obtains section theoretical diagram, be fitted section measured drawing and section theoretical diagram in image total station, by section
Measured drawing and section theoretical diagram are overlapped, obtain the cross-section diagram of an overlapping, and operator can be intuitive to see two cross-section diagrams
Between difference.
Image total station is erected at racing track side, including, image total station essence is put down, sets station, orientation, using more backsights
If the mode of station sets station, if station error is not more than 2mm；Station mode is set using more backsights, image total station is set up onto observation pier,
Observation pier is positioning support structure, is usually in the form of a column, and is fixed on the ground, and for setting up monitoring device, position monitor is set on top
Standby position, guarantee set station error no more than 2mm.
Compare the section measured drawing and section theoretical diagram more specifically further includes, generates color contrast figure, pass through color
Error size is distinguished, generalling use blue indicates that error is small, and the deeper error of blue is smaller, indicates that error is big with red, red is got over
Deep error is bigger, and different error degrees is distinguished by color, further promotes the Discussing Convenience of observation.
Along the axial section of racing track direction of advance scanning concrete surface, carried out after casting concrete 1~2 hour,
That is being scanned after solidifying 1~2 hour after casting concrete, concrete tentatively solidifies at this time, and mobility is small, but also not
Solidification completely, if the discovery biggish position of error can modify in time.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, this hair
It is bright to be not intended to be limited to the embodiments shown herein, and be to fit to and the principles and novel features disclosed herein phase
Consistent widest scope.
