翻模技术在小跨径高墩柱薄壁空心墩中的应用

Application of Flipping Template Technology in Small Span High Pier Column Thin-wall Hollow Pier

结合云南永武高速公路项目建设,对翻转模板施工应用技术包括翻转模板施工技术原理、难点和关键技术进行了研究。结果表明:采用翻转模板技术对小跨径高墩柱薄壁空心墩进行施工,模板投入量少、利用率和周转率高,能够在多墩柱中循环使用,有效降低施工成本;易控制墩身出现偏心或扭转的情况,保证其垂直度;能提高施工速度,质量容易控制,施工条件要求低,不污染环境,施工安全稳定;较爬升模板施工设备投入少,成本低,施工简单。

With the Yongren-Wuding expressway in Yunnan project,flipping template construction application including flip ping the template construction technology principle,difficulties and key technologies.The results show that the flip of small span high template technology pier construction thin-walled hollow pier,template inputs,utilization and the high turnover less,can be in many of the pier recycling,effectively reduce the construction cost;Easy to control the piers introduced.eccentric or reverse the situation there,make sure its vertical degree;Can improve the construction speed,easy to control the quality and construction conditions of low demand,not pollution of the environment,the construction safety and stability;A climb the template construction equipment less input,low cost,simple construction.
