600t/30m移动模架在半径1000m弯道现浇箱梁的应用

Casting Curvy Continuous Box Girders of 1000-m in Radius in Situ with 600-t/30-m Shoring System with Movable Formwork

随着我国桥梁施工技术的进步,移动模架在现浇箱梁施工中的应用逐渐广泛,并逐渐应用于小半径弯道桥的现浇梁施工,金丽温高速公路丽青段第九合同段在半径1000m的弯道及缓和段上进行了600t/30m移动模架应用实践,并取得了成功,达到了较快的施工速度。

With the rapid development of the technology for the construction of bridges in our country, the application of movable formwork on casting box girders in situ is gradually widened, and on casting curvy continuous box girders of small radius in situ is gradually widened, too. The attempt to cast curvy continuous box girders of 1 000-m in radius and its transition in situ by 600-t/30-m shoring system with movable formwork has succeeded, with high construction speed, in No.9 Contracted Section of the Liqing Part of the Jinliwen Highway.
