This disclosure relates generally to stormwater management and, more particularly, to a stormwater chamber with a continuous curvature. The stormwater chamber may comprise a chamber body with a chamber wall, an apex, a base, and a first and second opening. The chamber wall may include a continuous curvature from the apex of the chamber body to the first and second openings and a continuous curvature from the apex of the chamber body to the base.

A manhole base assembly and a method for making the same employ a non-cylindrical, low-volume concrete base that is fully lined to protect the concrete against chemical and physical attack while in service. This lined concrete manhole base assembly may be readily produced using a modular manhole form assembly which can be configured for a wide variety of geometrical configurations compatible with, e.g., varying pipe angles, elevations and sizes. The form assembly is configurable to provide any desired angle and elevation for the pipe apertures to interface with various underground systems, and can be formed on-site to facilitate compatibility with existing structures. The assembly provides for flexible, modular construction of a wide variety of lined manhole base assemblies at minimal cost, reduced concrete consumption and reduced operational complexity. The modular nature of the production form assembly also facilitates reduced inventory requirements when various manhole base assembly geometries are needed.

A coupling for multi-wall, corrugated pipe, the pipe including a corrugated wall having a plurality of primary corrugations, is disclosed. The coupling includes a first pipe section having disposed at one end a bell portion, the bell portion having a portion of the corrugated wall and an outer wall; a second pipe section having disposed at one end a spigot portion, the spigot portion having a portion of the corrugated wall between an inner wall and an outer wall; and a gasket engaged between the corrugated wall of the bell portion and the outer wall of the spigot portion. A multi-wall, corrugated pipe section, and method for assembling a plurality of multi-wall, corrugated pipe sections, are also disclosed.

Multi-wall corrugated pipe couplings and methods

A coupling for multi-wall, corrugated pipe, the pipe including a corrugated wall having a plurality of primary corrugations, is disclosed. The coupling includes a first pipe section having disposed at one end a bell portion, the bell portion having a bell portion of corrugated wall and an outer wall; a second pipe section having disposed at one end a spigot portion, the spigot portion having a spigot portion of corrugated wall between an inner wall and an outer wall; and a gasket disposed in a groove extending around a circumference of the spigot portion and engaged between the bell portion of corrugated wall and the spigot portion of corrugated wall. A multi-wall, corrugated pipe section, and method for assembling a plurality of multi-wall, corrugated pipe sections, are also disclosed.

A pipe having an axially extending bore defined by a smooth inner wall fused to a corrugated outer wall is provided. The corrugated outer wall has axially adjacent, annular, outwardly-extending crests separated by valleys. The pipe further includes an outer layer fused to the outer wall, the outer layer having adjacent concave portions and convex portions, the concave portions being aligned with corrugation valleys of the outer wall so that each concave portion of the outer layer extends between at least two corrugation crests. A method of improving the resistance to deformation of a corrugated pipe having a smooth inner wall fused to an outer wall defined by annular crests and valleys is also provided.

Corrugated pipe with outer layer

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.

Coupler for joining plastic and concrete pipe

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 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&#xb0; 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. The pipe adapter is attached to the plate member intermediate the peripheral side edge and the tapered face interior edge. The collar is also disclosed in combination with plastic pipe, preferably corrugated.

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.
