浅谈高墩滑模施工技术

随着经济的不断发展,我国的公路、桥梁建设事业发展迅速。为了适应市场需求,如今的桥梁结构日趋复杂,高墩柱桥梁更是比比皆是。目前,我国高等级公路多采用长大隧道、高墩大跨度桥梁相结合形式穿越山岭重丘区。滑模施工浇筑混凝土相对于常规模板浇筑具有连续性好,进度快,质量好,材料消耗少等诸多优点。本文以汾河特大桥高墩施工为背景展开论述,结合同类建设工程中常出现的"地形复杂"、"工期紧张"、"安全风险大"等难题,对高墩柱桥梁墩柱滑模的结构设计及荷载计算做介绍,对高墩柱桥梁滑模施工过程中测量及纠偏措施,质量控制要点和保证措施做了详细的分析,旨在提高今后滑模施工的施工技术。并提出相应的政策建议,进而为高墩滑模施工提供参考依据。

On Construction Technology of High Pier Sliding Model

With the development of economy, China＇s highway and bridge construction develop rapidly. In order to meet market demand, the bridge structure is now becoming more and more complicated, high pier bridge so does. At present, China＇s high highway usually through the mountainous and hilly areas with form of long tunnel, bridge with high pier and long span combined. Comparing the common template pouring, the pouring of concrete sliding model construction has good advantages of continuity, high speed, good quality, low consumption of materials etc. Combined with the potential problems of similar construction projects often appear like ＆quot;terrain＆quot;,＆quot;construction period＆quot;, ＆quot;safety＆quot; and other problems, this paper discusses the high pier construction of Fenhe River Bridge, introduces the structural design calculation and load of high pier bridge pier sliding mode, analyses the measurement and correction measures for high pier bridge sliding model construction process, key points of quality control and assurance measures in detail, aims to improve the construction technology of sliding model construction in the future. And some corresponding policy suggestions are proposed so as to provide reference for high pier sliding model construction.
