Jacking device for concrete filled steel tubes and construction method thereof
The invention discloses a jacking device for concrete filled steel tubes. The jacking device comprises a ground pump conveying pipe connected with a ground pump, a hollow steel column used for pouringconcrete and a grouting hole formed in the surface of the steel column, an in-column flow stopping device is arranged in the steel column, and an electric control permanent magnet connecting device is arranged outside the steel column. The electric control permanent magnet connecting device comprises a flange plate, a connecting pipe and a magnetic suction cup, through holes are formed in the centers of the flange plate and the magnetic suction cup, the inner diameters of the through holes are not smaller than the hole diameter of the grouting hole, and the flange plate and the magnetic suction cup are connected into an integrated structure through the connecting pipe; and an electric pulse controller for controlling magnetization and demagnetization of the magnetic suction cup is installed on the magnetic suction cup, the flange plate is connected with a ground pump conveying pipe, the magnetic suction cup covers the outer surface of the steel column at the grouting hole and is attracted to the steel column under the action of magnetized magnetic force, and the center line of a through hole of the magnetic suction cup coincides with the center line of the grouting hole. The device is simple, convenient to operate, low in cost and high in turnover utilization rate.
本发明公开了一种钢管混凝土用的顶升装置，包括与地泵连接的地泵输送管、用于灌注混凝土的中空钢柱以及开设在钢柱表面的注浆孔，所述的钢柱内部设置有柱内止流装置，钢柱外部设置有电控永磁连接装置，所述的电控永磁连接装置包括法兰盘、连接管和磁性吸盘，法兰盘和磁性吸盘中心处均开设有通孔，通孔内径均不小于注浆孔孔径，法兰盘和磁性吸盘通过连接管连接为一体结构，磁性吸盘上安装有控制磁性吸盘充磁和退磁的电脉冲控制器，法兰盘与地泵输送管连接，磁性吸盘覆盖在注浆孔处的钢柱外表面上并通过充磁后的磁力作用吸附在钢柱上，磁性吸盘的通孔中心线与注浆孔的中心线重合。本发明装置简单、操作便捷，成本较低，周转利用率高。
