Construction method of circumferential road synchronous settlement type viaduct pier column
The invention discloses a construction method of a circumferential road synchronous settlement type viaduct pier column. The construction method comprises the steps of bearing platform forming, pier column forming and bearing platform circumferential road laying. The step of forming the bearing platform comprises excavation of a foundation pit, installation of a reinforcement cage of the bearing platform, installation of a bearing platform template, concrete pouring of the bearing platform and removal of the bearing platform template; the pier column forming comprises pier column template installation, construction platform installation, pier column concrete pouring and pier column template removal; the step of laying the road in the circumferential direction of the bearing platform comprises the substeps of side baffle installation, foundation pit original soil backfilling, pond slag backfilling, graded broken stone laying, cement base layer laying and asphalt pavement laying. The side baffle installation comprises the steps that side baffles perpendicular to the top face of the bearing platform are installed on the two sides, close to the road, of the top face of the bearing platform respectively, the outer sides of the side baffles are vertically aligned with the side faces of the bearing platform, and isolation layers are arranged on the outer sides of the side baffles and the side faces of the bearing platform. The method can effectively relieve bumps of roads around the pier stud bearing platform, and is particularly suitable for viaduct construction in soft soil areas.
本发明公开了一种周向道路同步沉降式高架桥墩柱的施工方法，包括承台成型、墩柱成型以及承台周向道路铺设；承台成型包括挖设基坑、承台的钢筋骨架安装、承台模板安装、承台混凝土浇筑和承台模板拆除；墩柱成型包括墩柱模板安装、施工平台安装、墩柱混凝土浇筑和墩柱模板拆除；承台周向道路铺设包括侧挡板安装、基坑原土回填、塘渣回填、级配碎石铺设、水泥基层铺设和沥青路面铺设；侧挡板安装包括：在承台顶面靠近道路的两侧分别安装垂直于承台顶面的侧挡板，使侧挡板的外侧与承台侧面上下对齐，并在侧挡板的外侧与承台侧面设置隔离层。本发明可以有效缓解墩柱承台周边道路的鼓包，尤其适用于土地性质为软土地区的高架桥施工。
