The coordinate at the control point in the bridge floor center of circle is exported, timber is squeezed at control point, and center position is accurately drawn in stake top, is followed closely
Sub- cap exposes stake top about 1cm.
Second step, will mitigate helical curve track bridge floor along P1-P2 as shown in Figure 1-... P10-P11 outboard wheels
Exterior feature expansion, using this outline camber line projection straight line in the horizontal direction as the base of right angled triangle, between every layer of bridge floor
Another right-angle side of the difference in height as right angled triangle, bevel edge of the outline camber line as right angled triangle, so as to obtain such as Fig. 2
Shown illustraton of model II.
Third walks, according to building module, by the level of spigot-and-socket steel pipe form bracing system used in this present embodiment
Pole length is two kinds of specifications of 850mm and 1150mm, it is contemplated that upright bar uses φ 48mm × 3.5mm steel pipes and concreting process
It is constructed using automotive pump, in order to make the flexure plane of bridge floor bottom plate more smooth, the spacing of column framed bent should not be excessive, therefore mitigates spiral shell
The upright bar spacing of rotation curved lanes bridge floor outer contour is set to 900mm.
Helical curve can will be mitigated using the MEASURE orders (spacing decile, 900mm) in computer AUTOCAD softwares
Track bridge floor outer contour is divided into 30 sections, and every section of corresponding central angle θ is 6 ゜, using the center of circle of track bridge floor as starting point, 6 ゜
For central angle, a plurality of circular arc radioactive ray are drawn successively, and the upright bar absolute altitude on every circular arc radioactive ray is consistent.Circular arc radiation simultaneously
The outline camber line for mitigating helical curve track bridge floor is uniformly divided into multistage by line.
4th step using DIST orders (measurement) in computer AUTOCAD softwares is measured and mitigates helical curve track successively
The distance between each spacing Along ent, the distance measured is identified successively in illustraton of model II on bridge floor outline camber line projection line
Right angled triangle base, so as to obtain multiple spacing Along ents.
5th step, excessively each spacing Along ent, which does vertical line and extends to, to be mitigated in the bridge floor outline camber line of helical curve track simultaneously
Obtain a corresponding intersection point, measured automatically using DIST orders in computer AUTOCAD softwares spacing Along ent with it is corresponding
The distance between intersection point obtains corresponding upright bar absolute altitude.As shown in figure 4, with 37# circular arcs radioactive ray 2 until 46# circular arcs radiate
For circular arc radioactive ray between line 11, the Z in following tableiIt is worth to mitigate on the bridge floor outline camber line projection line of helical curve track
Height difference between each spacing Along ent and corresponding intersection point.
With spirit level by the height difference mark in the upright bar of support system, bridge can be obtained out by the point generated after mark
The horizontal absolute altitude of the steel pipe support of face bottom surface template, lumps of wood keel and supporting square timber keel, and put using this as each layer and install bridge
The control point of face bottom plate and lumps of wood keel absolute altitude.

While, the front of timely calibration template and the verticality of side are conducive to the Integral correction of later stage template.Model sheetinstallat terminates
It is reinforced immediately, due to being circular arc wall, reinforcing wall template can not use steel pipe, it is necessary to use the reinforcing bar of φ 16 instead.
7th step is followed closely track web bottom surface template 15 in lumps of wood keel 14 with bamboo slab rubber, after bottom surface template 15 is laid,
Horizontal alignment control point is led in bottom surface template 15, in this, as the control line for installing Side shuttering, horizontal alignment control point
Circular arc fixed point tangential method can be crossed by direct cable method or decile to determine.
Side shuttering uses waste and old glued board, because old glued board plasticity is preferable, easily curves certain radian, and save
Material improves template utilization rate.It after bridge floor web Side shuttering installs to a certain extent, needs to be checked in time, and in time
Carry out necessary adjustment, such as the corner angle of the smooth of bottom surface template, Side shuttering composition circular arc.Finally in Side shuttering periphery
One of 16 steel reinforcing of φ is added at upper and lower position respectively, as the control molding measure of Side shuttering curve.
8th step, the helical curve circular arc track bridge floor web take double two-way concrete slab to bind, and transverse steel 13 is i.e. just
For moment of flexure muscle using 16 steel bar arrangements of φ under, longitudinal reinforcement 12 is that negative bending moment rib uses 14 steel bar arrangements of φ in upper, transverse steel
13 and 12 vertical distribution of longitudinal reinforcement, at the same the extended line of longitudinal reinforcement 12 be all from the center of circle radially outward.The blanking of reinforcing bar backstage
It is modeled in the process using computer CAD, the overlapping part and cutting length of reinforcing bar, control is determined in strict accordance with the curvature of bridge floor web
The proportion of goods damageds of prepared material.Working efficiency is not only increased, and also improves cutting stock precision.
9th step, concreting.Concrete is poured using automotive pump, with reference to the layout characteristics of screw lane car, is adopted
With vertical shear wall construction and the arrangement and method for construction of track web one-piece casting.Concrete is disposably poured too much to mould in order to prevent
Plate generates too big pressure, and the mass defects such as mould, swollen mould are run so as to generate.On the one hand, vertical shear wall concrete takes entirety
Placement layer by layer, carries out in three times, pours the terminal by runway every time to its starting point, ensures concrete in casting process by height
Place freely flow to lower, prevent aggregate be packed together cause to vibrate it is unreal.On the other hand, it with reference to the layout characteristics of bridge, pours
When building track web concrete, pour sequence and carried out from top to bottom along track web central axes to both sides, to ensure shuttering supporting
Overall stability of the system in casting process.
Tenth step, form removal.Form removable should follow first non-weight bearing area, rear load-bearing position and top-down tear open
Except principle carries out, and should symmetrically remove, so as to ensure the stabilization of entire support system.Since the span of bridge floor web is more than 8m,
The concrete strength pressure testing provided according to laboratory report is needed to determine the form removable time.Therefore, concreting finishes seven
In it, have to strengthen to concrete curing, appropriate temperature and enough humidity are kept, to meet the good hardening of concrete
Condition.
