Hoisting process of prefabricated pier stud of fabricated bridge
The invention discloses a hoisting construction method of a prefabricated pier column of a fabricated bridge. The hoisting construction method comprises the following steps of: S1, prefabricating a pier column; S2, hoisting a first section of pier column; S3, hoisting a second section of pier column; and S4, continuously completing hoisting of the bent cap and the cable body after hoisting of thefirst pier column and the second pier column is completed, conducting steel strand tensioning according to the designed tensioning force after hoisting is completed, so that the bearing platform, thepier columns and the bent cap are connected into a whole, and finally grouting in embedded pipes of the bearing platform, the pier columns and the bent cap. The hoisting construction method of the prefabricated pier stud of the fabricated bridge is high in construction speed, safe and simple in operation and easy in construction quality control, can effectively reduce the workload of on-site formwork erecting and concrete pouring, shortens the construction period, and can be widely applied and practiced in the fields of bridge construction, buildings and water conservancy projects.
本发明公开了一种装配式桥梁预制墩柱的吊装工法，包括以下步骤：步骤S1：预制墩柱；步骤S2：第一节墩柱吊装；步骤S3：第二节墩柱吊装；步骤S4：第一节墩柱和第二节墩柱吊装结束后，则继续完成盖梁以及索体吊装，吊装结束后，根据设计的张拉力进行钢绞线张拉，从而使承台、墩柱和盖梁连接为整体，最后对承台、墩柱和盖梁的预埋管中进行注浆。本发明涉及的装配式桥梁预制墩柱的吊装工法施工速度快、操作安全简单、施工质量易于控制，可有效减小现场支模及混凝土浇筑的工作量，缩短施工工期，在桥梁建设，建筑、水利工程领域都能得到广发实践和应用。
