MSS650自行式支承托架移动模架的设计与施工

富溪12号公路桥位于蜿蜒峡谷中,设计曲线半径550 m,桥墩为单、双无盖梁柱式墩,混凝土连续箱梁采用移动模架施工。该移动模架支承托架采用自行前移方式,移动模架施工不需要吊机配合,解决了在山区施工时大型起吊设备无法进场的难题。

Design and Construction of MSS650 Movable Shuttering Form with Self-Traveling Supporting Brackets

The Fuxi Highway Bridge No.12,with a designed curvature radius 550 m,is located at the meandering valley.The piers of the Bridge are of single-and double-column piers without capping beams and the concrete continuous box girders atop the piers are constructed by movable shuttering form.The supporting brackets of the shuttering form can travel forward by themselves according to the design,the construction by the form therefore can be carried out without the aid of the cranes and the problem that large lifting equipment are difficult to be mobilized to the construction site in the mountainous region is resolved.
