Abstract
The invention discloses a wire compression type strain clamp capable of passing through a wire releasing pulley. The wire compression type strain clamp comprises an aluminum pipe, a steel anchor and a drainage clamp component, wherein the aluminum pipe is a hollow circular pipe; the steel anchor is sleeved on one end of the aluminum pipe, and a wire is arranged in the other end of the aluminum pipe in a penetrating way and compression-jointed into a whole; and the drainage clamp component is clamped on the aluminum pipe and is integrally manufactured from a drainage clamp aluminum pipe, a drainage clamp body and a drainage clamp cover plate. The wire compression type strain clamp is characterized in that: the drainage clamp component is detachable; during compression joint of the steel anchor as well as the aluminum pipe and the wire and traction of the wire, the drainage plate is not arranged; after compression joint, a stick-shaped circular device is arranged on the end part of the wire and can smoothly pass through a wire releasing pulley channel through drawing of a traction steel wire, but the strain clamp body is not mechanically damaged. When traction is performed to an end point, the drainage clamp component is arranged to realize complete functions of the strain clamp.
