An installation tool for expanding a locking sleeve for interlocking ends of the sleeve, the tool including a hydraulic cylinder driving a clamp or push block having at least one engagement surface parallel to an edge surface of one of the interlocking ends of the sleeve. More specifically, the clamp or push block includes a pair of engagement members having at least one engagement surface parallel to the edge of one of the interlocking ends of the sleeve. During use, an anchor extending from the cylinder is inserted within an aperture adjacent one interlocking end of the sleeve, and the engagement surfaces are abutted against the other interlocking end of the sleeve. Thereafter, the clamp or push block is driven by the cylinder to bear against the edge of such interlocking end of the sleeve, thereby expanding the sleeve until the ends of the sleeve interlock to lock the sleeve in a radially expanded sealing condition.

A sealing member for sealing a joint between a pipe and a wall defining an opening is provided. The sealing member has an annular base, a projection, and preferably first and second annular flanges. The annular base has a bottom and first and second sidewalls. The projection is attached to the base for anchoring the sealing member within the wall. In some embodiments it extends radially outwardly from the base. The first and second annular flanges extend from opposite sidewalls of the base. The first and second flanges each have a top and a bottom surface. The top surfaces of each can have an annular depressed portion, and each of the bottom surfaces can have a plurality of grooves formed therein. Preferably, the base includes at least one cavity extending completely around the circumference of the sealing member. There is also disclosed the use of the sealing member in a concrete manhole structure having a wall defining an annular opening through which a pipe having an outer surface can pass so that a joint is defined between the wall and the outer surface, with the sealing member being encased in appropriate grout to secure the sealing member to the concrete structure. The sealing member thus effectuates sealing of the joint between the pipe and the wall defining the opening.

A highway culvert inlet collar is disclosed having a plate member and a pipe adapter. The plate member has a front face, a rear face, a peripheral side edge intermediate the front face and the rear face, and a tapered inlet face portion adjacent the front face. The front face has a front face effective width at least twice that of the tapered inlet face portion effective width of the tapered inlet face portion. The pipe adapter has a first end and a second end, an interior surface and an exterior surface. The front face has an interior edge and an exterior edge. The tapered inlet face portion is located centrally of the front face and is preferably angled 45° rearwardly from the front face. The pipe adapter is preferably oriented perpendicularly to the rear face. The tapered inlet face portion extends from the front face interior edge to a tapered face interior edge.

A pipe having an axially extending bore is defined by a pipe wall including a corrugated outer wall having axially adjacent annular outwardly-extending crests separated by valleys. The pipe wall also includes a non-linear outer layer having adjacent concave portions and convex portions. The concave portions are aligned with the corrugation crests of the outer wall so that the convex portion of the outer layer extends outwardly between at least two corrugation crests to provide improved resistance to deformation.

A plastic pipe coupler is provided having a plurality of sections connected to one another but with at least one gap between the ends of two sections which are adjacent to one another. Each of the coupler sections has an exterior surface and an interior surface, and is fabricated so that when taken together, the sections cooperatively circumvent a section of plastic pipe. Each bracket is secured to the exterior surface of one of the aforesaid sections of the coupler and has a base plate, a pair of sidewall plates attached to each base plate, and a crosspiece having a first end and a second end, the first end of which is in contacting relationship with one of the pair of sidewall plates, while the second end is in contacting relationship with the other of the pair of sidewall plates.
