Method.
Background technology
With the fast development of highway communication, mountainous area highway is more and more, and the ratio that bridge tunnel accounts for highway is more next
Bigger, because topography is precipitous, relative fall is larger, Bridges in Mountainous Areas towards developing across, directions Gao Dun greatly, or even occur hundred meters of height with
On.
Conventionally employed three-dimensional fix method, using space coordinate control pier shaft quadrangle, measuring instrument uses total powerstation.
Before bearing platform construction, pier shaft cross hairs is released first, shape steel bracket is carried out, pier shaft embedded bar is accurately positioned and is ensured entire
Pier shaft reinforcing bar does not shift in work progress, not skewed；Measuring accurate on pier shaft goes out four control points of template before template installation,
Using the inclination of perpendicular measurement module when template is installed, template directly measures pier shaft quadrangle after installation is complete using total powerstation
Coordinate and the theoretical coordinate of calculating compare, and template is adjusted using jack.
But tradition variable cross-section bridge Linear Control one side workflow is relatively more, another aspect shape steel bracket is easy production
Raw disturbance, it is more difficult to Thin-Wall Piers Linear Control.
Invention content
The present invention provides a kind of installation method of Novel variable-section bridge linear controller, it is therefore intended that solves the above-mentioned back of the body

Step 1 goes out to design axis coordinate bit after bridge reinforcement installation in the pier stud position surveying and locating for having poured completion
It sets；
Step 2, installation form, template are vertical with what is processed in advance respectively in stiff skeleton surrounding after installation is complete
Angle steel is connected with lateral angle steel spot welding, and one block of steel plate is respectively welded in the axial centerline of vertical angle steel and lateral angle steel；
Step 3 carries out construction lofting according to design axis coordinate using total powerstation and prism bar, and draws on the steel plate
Design axis coordinate position, connection four axis points simultaneously be arranged red line mark, then with steel tape measure crossing point of axes position away from
Actual range from pier stud edge to be poured；
Step 4 is adjusted according to design offset distance and protective layer thickness deviation, the axial location of split bolt adjusting template
It is whole.
Preferably, the length of the steel plate is 10cm, width 10cm, thickness 1cm.
Preferably, Work tool and material include vertical angle steel, steel plate, lateral angle steel, red line, color mark pen, steel tape,
