Bridge side span construction method
The invention relates to the field of road traffic construction, in particular to a bridge side span construction method which is low in construction difficulty, short in construction period, low in cost and high in safety and comprises the following steps: 1, firstly, after construction of a pier column, a suspended pouring section and a side span pier column is completed, mounting construction of a pier column counterweight structure is carried out on the side, away from the pier column, of the side span pier column, and the side span pier column is constructed; a side span concrete bridge section supporting structure is installed and constructed on the side, close to the bridge pier column, of the side span bridge pier column; secondly, frame building, formwork erecting and cast-in-place construction of the side-span concrete bridge section is conducted on the side-span concrete bridge section supporting structure, a weight pressing sand bag arranged on the pier column weight balancing structure and the pouring process of the side-span concrete bridge section on the side-span concrete bridge section supporting structure are synchronously loaded, and it is guaranteed that stress on the two sides of a side-span pier column is balanced; and 3, after construction of the side span concrete bridge section and the bridge cantilever casting section is completed, construction of a closure section is conducted, and final closure construction is completed. The method is especially suitable for closure construction of bridge side spans.
本发明涉及公路交通施工领域，尤其是一种施工难度低、工期短、费用低且安全性高的桥梁边跨施工方法，包括如下步骤：一、首先，施工完桥墩柱、悬浇节段以及施工完边跨桥墩柱后，在边跨桥墩柱远离桥墩柱一侧进行墩柱配重结构的安装施工，在边跨桥墩柱靠近桥墩柱一侧进行边跨砼桥梁段支撑结构的安装施工；二、在边跨砼桥梁段支撑结构上进行边跨砼桥梁段的搭架支模现浇施工，其中，墩柱配重结构上设置的压配重砂袋，与边跨砼桥梁段支撑结构上边跨砼桥梁段的浇筑过程同步加载，保证边跨桥墩柱两侧受力平衡；三、边跨砼桥梁段及桥梁悬浇节段均施工完后，进行合拢段的施工，并完成最终的合拢施工。尤其适用于桥梁边跨的合拢施工之中。
