摘要
A joint restraint for deforming an outer diameter of a pipe for insertion into a socket. The joint restraint can selectively mount to a portion of an irregularly shaped pipe having a maximum outer diameter that differs from a desired substantially constant outer diameter. The joint restraint can have a circumferential ring body surrounding a central axis. A plurality of jacking assemblies can be secured to a portion of the ring body. Each jacking assembly can have a frame and a jacking bolt. The frame can have a threaded aperture that can receive the jacking bolt. Each jacking bolt can be selectively actuatable for radial movement relative to the central axis to deform the pipe proximate the maximum outer diameter of the pipe by selectively urging an outer surface of the pipe to the desired substantially constant outer diameter.
