高速公路特大桥独柱墩预应力盖梁施工技术

Construction Technology for Pre-stressed Copings of Single-pillar Piers of Super-large Highway Bridges

随着我国高速公路的发展,独柱墩预应力盖梁将被广泛应用到高速公路桥梁工程中。结合常(德)张(家界)高速公路工程狗子滩特大桥工程,详细介绍了托架支模技术在独柱墩预应力盖梁施工中的应用情况及施工工艺。

As the development of highways in China, pre-stressed copings for single-pillar piers are widely used on highway bridges. Taking Gouzitan super-large bridge on Changde -Zhangjiajie highway as example, the auther presents ＂in detail the application of the brackets and formwork supports in the construction of the pre-stressed copings of the singlepillar piers and the construction technology of the pre-stressed copings.
