桥梁转体施工是一种从上世纪40年代逐渐发展起来的架桥工艺,目前很多跨铁路、跨公路桥梁的建设过程中都一直在使用桥梁转体施工工艺。桥梁转体施工就是将非设计轴线部位的桥梁结构浇筑成形之后,再经过转体到达指定位置的一种施工方法。在此,本文主要介绍了桥梁转体施工工艺及竖转法和平转法两种关键施工技术。
Bridge construction is a swivel from the 1940s gradually developed bridge technology, many cross-railway, cross-highway bridge construction process have been using the bridge swivel construction process. The construction of the bridge is a kind of construction method of pouring the bridge structure of the non-designed axis part to the designated position after the turning. Here, this article mainly introduces two key construction technologies of bridge swivel construction technology and vertical rotation method and horizontal rotation method.
