Not sealing-off when bed die adjusts antiarch.Walking access path is set in the middle of pedestal, drainage sunk well is carried out, in order to install and workman's dimension
Shield.
2 bed dies are installed：Template uses bed die bag side form form, and die cavity forming accuracy≤0.1mm, fabrication error is not more than
2mm.The system of bed die 7 mouth template 9 under bed die, lower side form 8, shearing groove is constituted.Bed die is segmented to be made, and panel uses δ 12mm
Steel plate, back cord is used is locked between I20 shaped steel, section by bolt and alignment pin 15, and panel piece is used and is welded to connect, weld seam
Polish flat, bed die fulcrum is shelved shaped steel 6 by ribbed plate with the pre-buried angle steel in pedestal bottom surface and is connected.Bed die section assembling is used and hung
Machine, hand fit, the accurate setting-out of total powerstation, spirit level control plane elevation, bed die flatness control≤3mm.
The lower high 50mm of side form, it is suitable for reading to output semicircular notch by bar diameter and arrangement spacing, for framework of steel reinforcement bottom
Reinforcing bar is positioned.Lower side form presses bridge floor board size, is locked at bolt and alignment pin on bed die.It is stripped for ease of concrete component, downside
Mould is vertically in 5 ° of angular outer inclines.
Shear mouth template under groove, by shearing groove design size, to make using δ 25mm steel plates, with bolt and positioning pin locked
On bed die, precise positioning shearing groove, seam crossing pad rubber blanket mortar leakage prevention.
3 reinforcing bar colligations：Vertical, horizontal reinforcing bar stopper slot 23 and mould truss 24 are set on reinforcing bar sizing mould bases.Bottom layer of the reinforcing steel
After the completion of net colligation, the fast-easy closing-up net 26 made and its skeleton 25 of putting more energy into are placed to shearing groove design attitude, then tied up
Prick top mat, framework of steel reinforcement forming dimension allowable error ± 10mm.After framework of steel reinforcement shaping, install and in advance should by layout design
Hydraulic piping, pipeline is positioned by U-shaped reinforcing bar, positioning arrangement spacing 500mm.Fast-easy closing-up net is fabricated to type by mold of shaping,
Penetrated during installation with reinforcing bar, the perforate of pipeline monitor position.Framework of steel reinforcement is transported using many hoisting point hoists, to prevent from tying up at Heave Here
Bundle comes off and reinforcing bar deformation, and nearby reinforcing bar colligation point need to carry out welding reinforcement processing to suspension centre.
4 side forms are installed：Side form system 27 groups of mouth template on upper side form 11, end mould 21, baffle 20, movable shearing groove
Into.Upper side form is segmented to be made, and highly subtracts lower side form height for layout design bridge floor plate thickness, segmental length is with 1.5~2m
Left and right is advisable, panel use δ 12mm steel plates, comb shape pore structure, comb shape hole 14 is up-small and down-big to be easily installed and positions upper strata steel
Muscle, back cord 12 uses and one of back cord is set in the middle of δ 8mm steel plates, each two comb shape hole, and back cord height is highly consistent with upper side form,
The flanged plate 13 of upper side form section termination is shaped to inverted L-shaped, and lower mouth is advisable away from 10~20mm of bed die spacing, thin for padding system
Steel plate 19.Upper side form is torn open using underthrust method peace, is locked between section with bolt and alignment pin 15.Hold mould be single-unit it is overall into
Type, panel uses δ 12mm steel plates, and anchor box and back cord use δ 8mm steel plates.Baffle uses δ 6mm steel plates, and upper and lower opening presses steel
Muscle cloth smears closely connected on the inside of side form after dilution retarder, blending bolt fastening away from semicircle notch is opened up.Shear groove framework suitable for reading
Made and be molded using angle steel, by reinforcing bar cloth away from notch is opened up, is fixed in top bars mesh sheet, built-in adjustable bolt 28 4
Corner sets spigot 29 to be connected with skeleton 25 of putting more energy into.
5) concreting：Concrete is to mix C50 concrete certainly, and slump 5-8cm, concrete formulation uses low water-cement ratio
(ratio of mud is 0.3), gel material content >=490kg/m3.Stirred during mixing using the forced action type that stirring efficiency is high, uniformity is good
Mix machine, mixing time extends 40s than normal concrete, ensure in stirring dry mixing time of compound (cement, sand, rubble) >=
30s, makes compound reach sufficient uniformity, then combined material is stirred into be evenly distributed, the concrete of solid colour, always
Mixing time >=3.5min.Concreting is carried out continuously, and one-shot forming does not set construction joint.Because component thickness is relatively thin, it is
Ensure concrete density, planarization, combined using " three shake " (bottom surface attachment is shaken, surface vibration apparatus for leveling and insertion shake)
Construction method is controlled.I.e. based on bottom surface attachment dither 40, lay, sequentially opened during concreting in quincunx
Vibrator is opened, a vibrating time control of respectively shaking is in 15s or so；Shake blind spot, reinforcing bar compact district of attachment is vibrated using insertion auxiliary of shaking,
A vibrating time of respectively shaking about 20~30s；Surface is flattened using vibration leveling apparatus.Covering watering in time after the completion of concreting
Maintenance.
6) form removable：After concrete strength reaches regulation requirement, the dismounting of side template can be carried out.Using manually matching somebody with somebody
Join the two sections of a bridge, etc gantry crane form removal, first unclamps template and concrete surface using instrument during form removal, admits air into concrete body and template
Between flow, concrete slowly cools, dry, and then removes template, concrete is directly contacted with extraneous.
7) transverse prestress is constructed：Transverse prestress construction by stages, makes to store up with enough stress during transhipment floorings
It is standby, while reducing concrete creep shrinks the loss of prestress caused, improve component resistance to overturning.Tensioning uses single list
End alternating method is constructed.After tensioning, hole path pressure grouting is carried out immediately, to prevent corrosion, mud jacking construction using Intelligent mud jacking machine with
Special grouting material, mud jacking carries out sealing off and covering anchorage to sealing off and covering anchorage position in time after terminating.
