Jacking type construction method for segment prefabricated assembled pier column
The invention relates to a jacking type construction method for a segment prefabricated and assembled pier column. The jacking type construction method comprises the following construction steps that S1, a bearing platform is constructed, and pier column segments are prefabricated; and S2, platform erection. And S3, jacking equipment is installed. And S4, the first pier column section is conveyed in place. And S5, the pier column sections are jacked for the first time. And S6, the jacking equipment is converted. And S7, the pier column sections are jacked for the second time. And S8, the second pier column section is conveyed. And S9, lowering the first pier column section. And S10, sleeve grouting connection construction. And S11, the pier column sections are jacked continuously. And S12, the platform is dismantled. And S13, lowering the whole pier column. And S14, the bearing platform is connected with the pier column. And S15, equipment is dismantled, and the road surface is recovered. According to the construction method, large hoisting equipment does not need to be adopted, construction is convenient and fast, economical efficiency is good, the construction process is conducted on the ground and within the low height, construction safety is high, and the application of the prefabricated pier column in the high-pier bridge can be improved through the construction method.
本发明是一种节段预制拼装墩柱顶升式施工方法，包括以下施工步骤：S1.承台施工及墩柱节段预制。S2.平台架设。S3.顶升设备安装。S4.第一节墩柱节段输送就位。S5.墩柱节段第一次顶升。S6.顶升设备转换。S7.墩柱节段第二次顶升。S8.第二节墩柱节段输送。S9.第一节墩柱节段下放。S10.套筒灌浆连接施工。S11.墩柱节段持续顶升。S12.平台拆除。S13.墩柱整体下放。S14.承台与墩柱连接。S15.设备拆除，恢复路面。本发明无需采用大型吊装设备，施工方便快捷，经济性好，且施工过程均在地面以及较低的高度内进行，施工安全性高，本发明提供的施工方法可提高预制墩柱在高墩桥梁中的应用。
