一种桩基用液压挤扩装置及方法制造方法及图纸

本发明专利技术涉及一种桩基用液压挤扩装置及方法，该装置包括承接装置和与承接装置连接的挤扩臂；所述挤扩臂由上挤扩臂和与上挤扩臂铰接的下挤扩臂组成；其特殊之处在于：所述上挤扩臂和/或下挤扩臂包括第一臂、第二臂和支撑臂；所述第一臂与第二臂铰接；所述支撑臂的一端与所述第一臂和/或第二臂铰接，所述支撑臂另一端与承接装置铰接；本发明专利技术双缸双向挤扩设备沿圆周均匀布置上支撑臂或下支撑臂在水平方向受到的作用力如果不能平衡掉，则水平力传给支撑套管，支撑套管将水平力传递给外活塞杆相连套管，外活塞杆相连套管将力传至外活塞杆，这样可以避免支撑套管将水平力传递给将内活塞杆造成其弯曲。

Hydraulic squeezing and expanding device for pile foundation and method

The invention relates to a pile squeezing device and method for hydraulic, the device comprises a supporting device and supporting device connected to the squeezed arms; the squeezed arms by the arm and squeezed and squeezed arm under the squeezed arms; the utility model is characterized in that the squeezed arms and / or squeezed arm comprises a first arm, a second arm and a supporting arm; the first arm and the second arm is hinged with the support arm; one end of the arm and the first and / or second arm, the other end of the supporting arm and the supporting device is hinged; the invention of double cylinder double squeeze equipment along uniform arrangement of the support arm or the support arm in the horizontal direction is the force if not balanced, horizontal force to the supporting sleeve, the supporting sleeve will force to the level of the outer piston rod is connected with the outer casing, the piston rod is connected to the outer casing will force the piston rod, which can To avoid supporting the sleeve, the horizontal force is passed to the piston rod to cause it to bend.
