Installation method of bridge underwater buttress steel pipe column
The invention discloses an installation method of a bridge underwater buttress steel pipe column, the buttress steel pipe column is divided into a first steel pipe and a second steel pipe, the first steel pipe and the second steel pipe are connected through a connecting piece, the installation method comprises the following steps: S1, the buttress steel pipe column and a reinforcement cage of a buttress pile foundation are welded into a whole; s2, an outer frame of a buttress limiting device is installed on the pile foundation steel casing; s3, the buttress steel pipe column and the buttress pile foundation reinforcement cage are integrally hoisted into the pile foundation steel casing, and the overall height of the buttress steel pipe column and the overall height of the reinforcement cage are adjusted; s4, the perpendicularity of the buttress steel pipe column is adjusted, and a limiting piece of the buttress limiting device is installed after adjustment is completed; and S5, buttress pile foundation concrete is constructed, and the buttress limiting device is dismantled. According to the mounting method of the buttress steel pipe column, the construction procedures are reduced, the construction difficulty is lowered, the working efficiency is improved, and the perpendicularity of the buttress steel pipe column is easy to adjust, short in fine adjustment time and high in precision.
本发明公开了一种桥梁水中支墩钢管柱的安装方法，支墩钢管柱分为第一钢管和第二钢管，第一钢管和第二钢管通过连接件连接，安装方法包括以下步骤：S1，将支墩钢管柱与支墩桩基的钢筋笼焊接成整体；S2，在桩基钢护筒上安装支墩限位装置的外部框架；S3，将支墩钢管柱与支墩桩基钢筋笼整体吊装至所述桩基钢护筒内，调整支墩钢管柱与钢筋笼整体的高度；S4，对支墩钢管柱的垂直度进行调校，调校完成后安装支墩限位装置的限位件；S5，施工支墩桩基混凝土，拆除支墩限位装置。本发明所述支墩钢管柱的安装方法减少施工工序，降低施工难度，提高了工作效率，且支墩钢管柱垂直度的调整简单，微调时间短，精度高。
