Full pile casing cast-in-situ bored pile construction device and construction method
The invention belongs to the technical field of pile foundations, and particularly relates to a full-pile-casing cast-in-situ bored pile construction device and method. The full-pile-casing cast-in-situ bored pile construction device comprises a crawler chassis, a hydraulic cylinder, a U-shaped top plate and an electric push cylinder; a plurality of hydraulic cylinders are arranged in the middle of the crawler chassis, a U-shaped top plate is arranged at the top ends of piston rods of the hydraulic cylinders, a plurality of electric push cylinders are evenly arranged on the outer ring of a groove of the U-shaped top plate, and the ends of the piston rods of the electric push cylinders make contact with a pile casing. During working, the crawler chassis moves to the outer side of an embedded pile casing, so that a groove of the U-shaped top plate moves to the outer ring of the embedded pile casing, the hydraulic cylinder pushes the U-shaped top plate to be lifted, so that the U-shaped top plate is aligned with the top of the embedded pile casing, a crane lifts a new pile casing to the top of the U-shaped top plate, and the electric push cylinders on the periphery push the new pile casing to move; and the new pile casing is aligned with the buried pile casing, so that the operation difficulty of constructors is reduced, and the construction efficiency of the constructors is improved.
本发明属于桩基础技术领域，具体的说是一种全护筒钻孔灌注桩施工装置及施工方法，包括履带底盘、液压缸、U形顶板和电推缸；所述履带底盘的中部设置有多个液压缸，所述液压缸的活塞杆顶端设置有U形顶板，所述U形顶板的凹槽外圈均匀设置有多个电推缸，多个所述电推缸的活塞杆端头接触护筒；工作时，履带底盘移动到埋设的护筒的外侧，使得U形顶板的凹槽移动到埋设的护筒的外圈，液压缸推动U形顶板抬高，使得U形顶板与埋设的护筒顶部对齐，吊车将新的护筒吊到U形顶板的顶部，四周的电推缸推动新的护筒进行位移，使得新的护筒对齐埋设的护筒，从而降低了施工人员的操作难度，提高了施工人员的施工效率。
