Joint squeezing and expanding device for PHC pipe pile
The connector squeezing and expanding device comprises a connecting cylinder, a squeezing and expanding forming machine, a window piece and a bottom support, the connecting cylinder is vertically fastened between the two PHC pipe piles, the movable window piece is arranged on the side wall of the connecting cylinder, and the bottom support is located below the connecting cylinder. The extrusion and expansion of the PHC pipe pile joint are realized by lifting the vertical rod of the extrusion and expansion forming machine upwards, and concrete is poured into the extrusion and expansion cavity through the hollow vertical rod with the scales, so that the concrete expansion head is formed. According to the method, the defect that the PHC pipe pile cannot be squeezed and expanded is overcome, the application range of the PHC pipe pile is expanded, the pulling resistance and the pressure resistance of the PHC pipe pile are greatly improved, the double functions of squeezing and expanding forming and concrete pouring can be achieved at the same time, positioning is accurate, the concrete pouring amount is controllable, and convenience and high efficiency are achieved.
本发明提出一种用于PHC管桩的接头挤扩装置，包括连接筒、挤扩成型机、窗片、底托，连接筒竖直紧固在两个PHC管桩之间，连接筒的侧壁上设置可活动式窗片，底托位于连接筒的下方。通过向上提拉挤扩成型机的竖杆，实现PHC管桩接头的挤扩，并通过带有刻度的中空竖杆向挤扩空腔内浇筑混凝土，从而形成混凝土扩大头。本发明弥补了PHC管桩不能挤扩的缺点，扩大了PHC管桩的应用范围，大幅度提高了PHC管桩的抗拔和抗压能力，并能够同时实现挤扩成型和灌注混凝土的双重功能，定位准确，浇筑混凝土量可控，方便高效。
