跨襄渝铁路立交桥滑移式防护棚架施工技术

Construction of Sliding Protective Shed Frame for the Overpass Across Xiangyang-Chongqing Railway

以十堰至白河高速公路跨襄渝铁路立交桥工程为例,介绍了滑移式防护棚架的施工技术。相比于传统的防护棚架形式,采用滑移式防护棚架,虽然增加了一些施工内容和过程,但极大地节约了材料,而且有利于棚架的拆除施工。

Taking the overpass project from Shiyan to Baihe expressway as an example,this paper introduces the construction scheme of sliding protective shed frame for the overpass across Xiangyang-Chongqing railway. Compared with the traditional protective shed frame type,the sliding one should increase the construction content and process,but the materials were saved enormously,and the construction would be dismantled more quickly and easily.
