Abstract: Device for supporting a pipe joint which joins a substantially vertical pipe with at least one substantially horizontal pipe. In one embodiment, the device comprises (a) a base member, (b) a clamp sized and configured to clamp the vertical pipe, and (c) at least one arm member which is attached at one end to the base member and attached at the other end to the clamp. The devices of the invention provide support or reinforcement to conventional pipe joints to enable those joints to better withstand gravitational and other forces over extended periods of time. Improved underground pipe systems employing pipe joints, as well as methods for providing support to pipe joints, are also described.
