LI MIN / WANG YONGGANG / WANG HAIBO / HUANG LEILEI / CONG ZHEN

The invention discloses a pile-column connection accurate positioning structure and a construction method. The pile-column connection accurate positioning structure comprises a steel stand column, a drilled pile, a control frame connected to a supporting platform, a first jack connected between the control frame and the horizontal direction of the steel stand column, and a second jack connected between a protective cylinder and the horizontal direction of the steel stand column. During construction, by arranging the control frame, the steel stand column can be effectively borne; by arranging the supporting platform, the supporting platform can be fixedly connected through a bearing arm pre-connected to the steel stand column; by arranging the first jack and the second jack, installation is facilitated, and adjustment, clamping and fixing are facilitated; and the first jack and the second jack are jointly controlled through a verticality adjusting controller, and cooperation and synchronous control are facilitated.

本发明公开了一种桩柱连接精准定位结构及施工方法，定位连接结构包含钢立柱、钻孔桩、连接于支承平台上的控制架、连接于控制架和钢立柱水平向之间的第一千斤顶、连接于护筒与钢立柱水平之间的第二千斤顶。施工时，本发明通过控制架的设置，可有效的承载钢立柱；支承平台的设置，可通过钢立柱上预先连接的承重臂进行固定连接；通过第一千斤顶和第二千斤顶的设置，利于安装且便于调整和夹持固定；第一千斤顶和第二千斤顶均通过调垂控制仪联合控制，便于协作和同步控制。
