Deeply-buried anchorage device
The invention discloses a deeply-buried anchorage device. The deeply-buried anchorage device comprises a deeply-buried sleeve, a working anchorage device body and an extension sleeve. The deeply-buried sleeve and the working anchorage device are sequentially distributed in the pre-buried direction and fixedly connected. One axial end of the extension sleeve penetrates through and is detachably positioned in the deeply-buried sleeve, and the other axial end of the extension sleeve extends out of the deeply-buried sleeve; a transition backing ring extending towards the outer side in the circumferential direction is arranged on the circumferential side of at least one of the deep-buried sleeve and the working anchorage device, and the two axial ends of the transition backing ring are exposed in the opposite directions. According to the deeply-buried anchorage device, the jack can be led out of concrete for tensioning operation through the extension sleeve, installation of the jack is simplified, and the operation reliability of the jack is improved; according to the deeply-buried anchorage device, the stress area of the tensioning end is increased through the extension sleeve, the stress characteristics of the deeply-buried anchorage device and a construction body during prestress tensioning are improved, the structure of the construction body cannot be damaged easily, the safety of the construction body is greatly improved, and follow-up mud jacking and anchor sealing are facilitated.
本申请公开了一种深埋锚具，包括深埋套筒、工作锚具和延长套筒；深埋套筒和工作锚具二者沿预埋方向依次分布且固定连接；延长套筒的轴向一端穿设且可拆卸地定位于深埋套筒内，延长套筒的轴向另一端朝深埋套筒外伸出；深埋套筒和工作锚具二者中至少一者的周侧设有朝周向外侧延伸的过渡垫环，过渡垫环的轴向两端分别朝相反方向暴露。该深埋锚具通过延长套筒可以将千斤顶引出至混凝土外进行张拉作业，简化了千斤顶的安装并提高了千斤顶的作业可靠性；该深埋锚具通过延长套筒增大了张拉端的受力面积，改善了预应力张拉时深埋锚具与施工体的受力特性，不免轻易破坏施工体的自身结构，大幅提高了施工体的安全性，有利于后续的压浆和封锚。
