Construction method for replacing prefabricated pier column with cast-in-place bridge pier column
The invention belongs to the technical field of bridge construction, and relates to a construction method for replacing a prefabricated pier column with a cast-in-place bridge pier column. Comprising the steps that S1, a bearing platform is constructed according to construction design requirements, positioning ribs are connected to the upper ends of bearing platform main ribs arranged corresponding to pier column construction positions, and the positioning ribs vertically stretch out of the upper portion of a bearing platform concrete body; a grouting sleeve is vertically arranged on the positioning rib in a sleeving mode and arranged on the upper surface of the bearing platform; s2, the lower end of the pier column main rib is inserted into the grouting sleeve, and the positioning rib and the pier column main rib are in coaxial butt joint; the multiple pier column main reinforcements located outside the grouting sleeve are connected through first pier column stirrups; s3, a pier column formwork is erected, the pier column main reinforcement, the first pier column stirrup and the grouting sleeve are located in the pier column pouring space, and a grouting pipe and a grout outlet pipe which communicate with the grouting sleeve extend out of the outer side of the pier column formwork; concrete is poured into the pier column pouring space, and the pier column formwork is dismantled after the concrete reaches the formwork dismantling strength; and grouting the grouting sleeve. And the construction period is saved.
本发明属于桥梁施工技术领域，涉及一种现浇桥梁墩柱取代预制墩柱的施工方法。包括步骤：S1，按照施工设计要求施作承台，在与墩柱施工位置相对应布置的承台主筋上端连接定位筋，使定位筋从承台混凝土本体的上方竖向伸出；将灌浆套筒竖向套设于定位筋上、且置于承台上表面；S2，将墩柱主筋的下端插入至灌浆套筒中，使定位筋和墩柱主筋同轴对接；将位于灌浆套筒之外的多根墩柱主筋通过第一墩柱箍筋相连；S3，搭设墩柱模板，使墩柱主筋、第一墩柱箍筋、和灌浆套筒位于墩柱浇筑空间中，使与灌浆套筒相连通的注浆管和出浆管从墩柱模板的外侧方伸出；向墩柱浇筑空间中浇筑混凝土，待混凝土达到拆模强度后拆除墩柱模板；向灌浆套筒中灌浆。利于节约工期。
