(2) assembling set shaped steel formwork: at first, the reinforcing bar of the vase-shaped columnar pier of viaduct is finished by the design drawing colligation, and transport to on-the-spot spelling and become vase-shaped pillar reinforcing cage; And be placed on the foundation platform through the flitch piece, four one of the set shaped steel formworks that processing and fabricating is good are pieced together to be located at and are positioned at the reinforcing cage outside, the every block length 2-3 of set shaped steel formwork rice on the flitch piece; The polylith set shaped steel formwork is set on the bridge pier short transverse, is horizontally arranged with two back-to-back channel-section steel bands on the every set shaped steel formwork, channel-section steel band two ends are provided with backing plate; Backing plate is provided with pulling eye; Laterally adjacent two templates are through to drawing lead screw locking, and the every horizontal and vertical edge of set shaped steel formwork all is provided with bolt hole, connects locking through bolt in the time of assembling; And adjacent two set shaped steel formwork edge tongue and grooves match; Paste with double faced adhesive tape between set shaped steel formwork tongue and the groove, prevent to mix the earth slurry and run off, flitch piece top also is provided with the absolute altitude that jack is used to adjust set shaped steel formwork;
(3) concreting: it is inner that the concrete slurry that configures is injected the set shaped steel formwork that assembles, but just one-time-concreting moulding after the maintenance.
Be vertically arranged with the channel-section steel stiffener on the above-mentioned set shaped steel formwork.
The technique effect that the present invention obtains:
1. the present invention's vase-shaped columnar pier one-shot forming of viaduct of constructing, easy construction, workable; Do not receive the restriction of fabricating yard condition, applied widely, can reduce cost; Solved scene molding construction at twice effectively; Opposite joint is always uneven between template, the middle construction difficult problem that one slit always arranged, and have comprehensive technology economic benefit preferably.
