山区高速公路由于受地形限制,桥梁所占的比例较高,而防撞护栏是结构建成后行车过程中惟一可见、影响造型美观的外露工程,因而工程的质量和进度在高速公路建设中占据着重要位置。本文以福建省永宁高速公路A14合同段桥梁防撞护栏施工为例,针对原有工艺存在的投入劳力多、进度慢等问题,提出了一套桥梁混凝土护栏模板整体移动施工工艺,介绍了该工艺在施工中的技术要点及运用,并分析达到的效果。实践证明,该技术具有较好的推广价值。
Due to the limited topography and the high proportion of bridges in the mountainous expressways, the crash barriers are the only exposed works that affect the appearance of the buildings after the structure is completed. Therefore, the quality and progress of the projects occupy the expressway construction Important position. This paper takes the construction of the bridge crash barriers in A14 contract section of Yongning Expressway in Fujian Province as an example. In view of the problems such as the labor cost and slow progress of the existing technology, a set of mobile construction technology of bridge concrete fence template is proposed. In the construction of the technical points and use, and analyze the results achieved. Practice has proved that the technology has a good promotional value.
