Highway bridge engineering construction method
The invention relates to a highway bridge engineering construction method. The method comprises the following steps that firstly, a pile foundation is poured; secondly, a foundation pit is excavated; thirdly, an operation area is dug; 4, breaking a pile head; fifthly, a first formwork is erected; sixthly, a cushion layer is poured; seventhly, bearing platform reinforcing steel bars are bound; eighthly, a second formwork and a third formwork are erected; ninthly, pier body embedded steel bars are in lap joint; tenthly, a bearing platform is poured; eleventhly, backfilling the foundation pit; twelfthly, binding pier body reinforcing steel bars, pouring a pier body, prefabricating a plate beam and erecting the plate beam; the operation area continues to be dug downwards on the bottom face of the foundation pit, the first formwork is erected on the periphery of the pile foundation, so that a protruding section can be formed when the bearing platform is poured and is embedded below the bottom face of the foundation pit, and the second formwork and the third formwork are erected to form an inserting part when the pier body is poured and are embedded below the upper surface of the bearing platform; the joints of the pile foundation and the bearing platform and the joints of the bearing platform and the pier body can better bear transverse loads, and the overall structural strength is enhanced.
本发明涉及一种公路桥梁工程施工方法,包括以下步骤：第一步，桩基浇筑；第二步，开挖基坑；第三步，挖设操作区；第四步，破桩头；第五步，支设第一模板；第六步，浇筑垫层；第七步，绑扎承台钢筋；第八步，支设第二模板和第三模板；第九步，搭接墩身预埋钢筋；第十步，浇筑承台；第十一步，回填基坑、第十二步，绑扎墩身钢筋、浇筑墩身、预制板梁、架设板梁；本发明通过在基坑底面继续向下挖设操作区，并在桩基周围支设第一模板，使承台浇筑时可以形成凸出段，并嵌套在基坑底面以下，支设第二模板和第三模板使浇筑墩身时形成插接部，并嵌套在承台上表面以下，使得桩基与承台、承台与墩身的连接处可以更好的承受横向载荷，增强整体的结构强度。
