Detailed description of the invention
Shown in Fig. 1 to Fig. 4 b, including step:
Preparation of construction:
The examination of science of bridge building, measurement control points layout and repetition measurement, concrete mix proportion experiment, solid concrete roabed construction conditions
Inspection and evaluation etc..
The scope of operation is cleared up:
For guaranteeing that solid concrete roabed concrete and bridge floor have good connection, by the contact surface dabbing of bridge floor, ponding is discharged, is made
With high-pressure blast descum, dust and foreign material, it is ensured that New-old concrete has stronger adherence force, it is ensured that Monolithic Track Bed Construction
Quality.Embedded ribs is checked one by one, by design requirement righting, and the reinforcing bar of corrosion is eliminated rust.
Surveying setting-out:
Control every 10m measuring errant center line control point on beam face, 3 in Curve Segment track centre by measuring control point
Point 5m arranges 1, and curve terminal, point of spiral to curve, point of curve to spiral, knick point respectively set one, with orbit centre control point as base
Quasi-releasing benchmark rail reference line, template contral sideline (line of ink marker mark), use the line of ink marker to orient vertically and horizontally by design requirement
The position of reinforcing bar.
Reinforcing bar binding:
Use in reinforcement yard's unified allocation of materials to lower units, processing, the operating type of on-the-spot colligation welding fabrication.Vertical and horizontal steel
Muscle is fixed by design requirement spacing colligation, and meets the requirement of concrete Minimal Protective thickness.
Multifunction railway adjuster sets up:

After, put relevant position by orbital curve line style reference data rail reference line, auxiliary support can keep multifunction railway to adjust
Whole device longitudinal stability, is put by prescribed distance between multifunction railway adjuster.
Benchmark rail gantry sets adjustment:
Benchmark rail is lifted on the rail pallet above the benchmark rail reference line of multifunction railway adjuster, utilize draw-in groove spiral shell
Female quickly assemble with the multifunction railway adjuster being well placed, use the aids such as vertical and adjustment bolt with
On the basis of benchmark rail reference line, adjust benchmark rail position, it is ensured that rail Curve, lock rail both sides after adjusting and adjust
Whole bolt.
Servo-actuated rail gantry sets adjustment:
Servo-actuated rail is lifted on the opposite side rail pallet of multifunction railway adjuster, utilize draw-in groove nut and multi-functional rail
Road adjuster quickly assembles, and uses the aids such as gauging rule and adjustment bolt on the basis of benchmark rail, adjusts servo-actuated
Rail position, the section of track system that composition gauge is qualified.
Sleeper (fastener) is installed:
Rail draws sleeper installation site by design sleeper pitch, sleeper and fastener system are installed on request.
Template erection:
Check that template flatness and template clean situation, brushing releasing agent.After determining template and the decorating position of use,
First laying by template sideline order and couple longitudinal mode plate and support, then press cross template sideline and set up cross template, cross template is adjusted
