A pipe joint for plastic pipe includes a bell member and a spigot member. The bell member includes a tubular plastic body wall having a metal reinforcement ring. The spigot member, which is insertable into the bell member, includes a tubular plastic body wall having an internal surface and an external surface and a longitudinal axis and metal reinforcement encased within the tubular plastic body wall. A plurality of plastic ribs extend from the external surface of the tubular plastic body wall and form a gasket channel.

Pipe joint and related method

A plastic, corrugated open bottom chamber includes features such as one or more of (i) sub-corrugation features on corrugation crests and/or corrugation valleys, (ii) stiffening fingers on the bottom of chamber foot portions, (iii) a viewport configuration that intersects only a single corrugation crest and (iv) a unitary end wall. A method of producing chambers with or without a unitary end wall using a common mold tool is also provided. A method of interconnecting chambers to form a chamber rows is also provided.

Plastic detention chamber for stormwater runoff and related system and methods

A pipe joint for plastic pipe includes a bell member and a spigot member. The bell member includes a tubular plastic body wall having a radially outer side including a pair of spaced apart circumferentially extending ribs and a metal reinforcement ring located between the ribs. The tubular plastic body wall includes a circumferential plastic ring portion extending between the ribs and radially exterior of the metal reinforcement ring to encase the metal reinforcement ring within the tubular plastic body wall. A radial gap may be provided between the plastic ring portion and the metal reinforcement ring to accommodate differing thermal shrinkage rates as between the two different materials. The spigot member, which is insertable into the bell member, includes a tubular plastic body wall having an internal surface and an external surface and a longitudinal axis and metal reinforcement encased within the tubular plastic body wall. A plurality of plastic ribs extend from the external surface of the tubular plastic body wall and forming a gasket channel.

A pipe manufacturing system and method for producing helically corrugated metal pipe is provided. The system and method utilize controlled profile formation.

A stormwater runoff detention system includes a system including an inlet, a first surge chamber, a second surge chamber and one or more storage chambers. The first surge chamber is connected to receive stormwater from the inlet prior to the second surge chamber or the storage chamber. The first surge chamber includes a discharge outlet and an overflow outlet to the storage chamber. The second surge chamber is connected to receive stormwater from the inlet primarily after the first surge chamber has begun overflowing to the storage chamber. The second surge chamber includes a discharge outlet and an overflow outlet to the storage chamber or to a second storage chamber.

Stormwater detention system and method

A corrugated structural metal plate includes longitudinally extending corrugations defined by alternating crests and valleys. Each of the crests and valleys includes longitudinally extending flat segments that are configured to reduce buckling of the plate when the plate is curved about an axis generally transverse to its longitudinal axis.

Corrugated structural metal plate

A slotted drain includes a drain pipe having an elongated narrow slot extending lengthwise along its top surface. A lower grate is rigidly secured to the elongated slot and is formed by a pair of bearing plates connected to one another by a series of spacer plates and connected to the edges of the elongated slot. The lower grate is connected to an upper grate initially in an adjustable manner such that the height and angle of the upper grate may be adjusted with respect to the lower grate and the drain pipe. The height of the upper grate with respect to the drain pipe is dependent upon the intended depth at which the drain pipe will be situated and the angle of the upper grate may, for example, correspond to the drainage slope at which the drain pipe will be set. Once the upper grate has been adjusted to the desired height and angle, the upper grate is rigidly secured to the lower grate. In a first preferred embodiment the lower grate telescopically receives the upper grate and in a second preferred embodiment the upper and lower grates are connected to each other by a pair of intermediate bearing plates.
