A webless corrugated dual wall foundation drain which is constructed as a hollow rectangular tubular member with an inner corrugated wall formed of HDPE and an integral outer smooth wall formed of the same material. The outer smooth wall of the foundation drain is attached to and integrally formed with the corrugations of the inner corrugated wall through a coextrusion process, thereby significantly enhancing the vertical beam stiffness of the foundation drain and eliminating the need for an internal supporting web.

An inspection system and method for scanning and recording defects in the surface of the smooth inner wall of dual wall corrugated plastic pipe during manufacture utilizing automated laser technology, in order to minimize potential disruptions in the manufacturing extrusion process and alleviate concerns as to improper formation of the inner wall. The inspection system includes conical laser pattern generator that passes through the dual wall corrugated pipe during the manufacturing process to complete 360 degree scan coverage of the surface of the inner smooth wall of the pipe. The inspection system further includes a set of cameras properly aligned to record comprehensive three dimensional coverage of the scanned image of the inner wall of the dual wall corrugated pipe. This inspection system and method has particular benefits in the manufacture of coilable dual wall corrugated plastic pipe, where the material make-up of the polymer melt used for the inner wall has been altered.

High flow capacity corrugated coilable dual wall plastic pipe having improved longitudinal flexibility and a bend radius sufficient to permit coiling and plowing of such pipe into the ground using automated installation equipment. The coilable dual wall pipe has an outer corrugated wall formed of a thermoplastic material such as high density polyethylene, and an inner smooth wall formed of a different more flexible and resilient thermo-bondable material that has an enhanced strain capacity and lower modulus of elasticity. The inner wall material also has enhanced mechanical properties which generally improve processing and help prevent excessive drag and tearing of the liner material during the manufacturing process. Suitable material blends for the inner wall incorporating a thermoplastic elastomer additive in combination with a thermoplastic material have proven suitable in providing the required longitudinal flexibility and pipe bend radius to permit the desired pipe coiling and plow installation without failure.

A heat-fusible gasket for affecting a flexible seal between two adjoining components of a coupling, such as the spigot end of a section of plastic pipe and a bell coupler to be fitted thereover. The gasket has an inner core which is constructed of an elastomeric material, and outer opposing sealing surfaces that are formed at least in part of a heat-fusible material that is compatible with the heat-fusible components with which the gasket is intended to engage. The gasket is co-extruded in continuous lengths with electrically conductive heat resistance wires embedded in the outer compatibly heat-fusible layers. For annular gaskets, the co-extruded lengths of gasket material may be cut and spliced into any desired diameter gasket. Upon connection to a power source, the gasket seal is perfected through electrofusion along the opposing sealing surfaces of the gasket, thereby providing enhanced sealing capability.

The present invention relates to a corrugated foundation drain. The drain is comprised of a plurality of segments attached in an end to end fashion. Each segment has a first end and a second end, wherein the second end of one segment can be attached to the first end of an adjacent segment. The drain is corrugated. The drain has sections of corrugations separated by spacers for longitudinal stability. A web is provided within the interior of the drain segments. The web can be vertically centered. In the preferred embodiment, the web can be removed from the first end to provide clearance for receipt of the second end. The second end further can have cleats that interface with the corrugations in the first end.

A bell and spigot coupling system is provided for joining corrugated plastic pipe which improves the coupling's sealing capability with increasing hydrostatic pressure, and causes a substantial component of the force generated therefrom to be absorbed axially through the coupled sections of adjoining pipe. The spigot end of one pipe which is received within a bell coupler for an adjoining pipe terminates in a small annular bed-forming rib which forms a gasket bed that holds a gasket compressed against a radially extending gasket sealing surface of the bell coupler. Inward protruding latches formed in the bell coupler engage the adjoining section of corrugated pipe to resist axial separation and hold the gasket compressed against the sealing surface of the bell coupler. The sealing surface of the bell coupler contours the spigot end of the adjoining pipe and forms radially constricting pathways at opposite sides of the gasket. The presence of either internal or external hydrostatic pressure on the coupling joint causes the gasket to wedge into one of the opposing radially constricted pathways, thus transferring the force generated by such pressure axially through the coupled sections of pipe.
