Expansion type prestress self-locking anchoring device
An expansion type prestress self-locking anchoring device solves the problems that in the prior art, the operation process of a bottom hole expanding procedure is tedious, the auxiliary operation time is long, a drilling tool is seriously abraded, replacement is frequent, the number of maintenance times is large, and the construction cost is high. Which comprises a plurality of steel strands arranged in a deep straight hole, and is characterized in that a plurality of groups of strand fixing rings which are vertically arranged are arranged on the plurality of steel strands, and the upper ends of the steel strands, which are positioned above an orifice of the deep straight hole, are connected with a positioning anchor disc; the lower end, located at the bottom of the deep straight hole, of the steel strand is provided with an expansion self-locking mechanism, the expansion self-locking mechanism comprises a self-locking base connected with the lower end of the steel strand, and an expansion wedge block is arranged between the outer side wall of the self-locking base and the inner wall of the deep straight hole. The structure is reasonable in design, compact in structure, convenient and fast to construct, capable of saving cost, wide in applicable rock stratum range and capable of effectively guaranteeing the stability of the steel strand prestress foundation structure, and an expanded bottom hole does not need to be formed in the bottom of a straight hole.
一种扩涨式预应力自锁锚固装置，解决现有技术存在的扩底孔工序操作过程繁琐，辅助作业时间长，钻具磨损严重、更换频繁，维护次数多，施工成本高的问题。包括设置在深直孔内的若干根钢绞线，其特征在于：若干根钢绞线上设置有若干组沿竖向布置的绞线固定环，钢绞线位于深直孔孔口上方的上端与定位锚盘相连；钢绞线位于深直孔孔底的下端设置有扩涨自锁机构，扩涨自锁机构包括与钢绞线下端部相连的自锁底座，自锁底座外侧壁与深直孔内壁之间设置有扩涨楔形块。其设计合理，结构紧凑，无需在直孔底部设置扩底孔，施工方便、快捷，节约成本，且所适用的岩层范围广，能够有效保证钢绞线预应力基础结构的稳定性。
