AI Technical Summary
Technical Problem
The existing external surge protection method cannot display stress after damage, resulting in inaccurate subsequent stress detection, limiting the use of anchors and data acquisition.
Method used
The multi-efficiency pressure-bearing pipe structure is adopted, and the preload control and stress display are achieved through the combination of preload control pipe, stress display pipe and anti-flush energy suction pipe, and the internal collapse and deformation are provided after being compressed, providing protection function.
Benefits of technology
In the absence of external tools, stress detection can be performed directly, avoiding the problem of inaccurate stress detection and providing multi-performance protection and detection functions.

Abstract
A mining multi-effect anchorage device comprises an anchorage device body, the anchorage device body penetrates through a multi-effect pressure-bearing pipe, and one end of the anchorage device body is an expanded end and cannot penetrate through the multi-effect pressure-bearing pipe. The multi-effect pressure-bearing pipe is arranged to be capable of controlling pre-tightening force and / or displaying stress and / or constant-resistance energy absorption; one end of the multi-effect pressure-bearing pipe abuts against the expansion end of the anchorage device body, the other end of the multi-effect pressure-bearing pipe abuts against the ball pad penetrating through the anchorage device body, and the multi-effect pressure-bearing pipe can only be located between the expansion end of the anchorage device body and the ball pad. The end, away from the multi-effect pressure-bearing pipe, of the ball pad abuts against a tray penetrating through the anchorage device body. An original external expansion type structure is replaced by an internal crumple mode, an original protection function is achieved, meanwhile, the function of bearing stress real-time detection can be provided during deformation, various advantages of an original structure are achieved, and meanwhile additional technical effects can be provided.
