Sub-floor drain conduit for water-control systems
First Claim
1. An elongate water-conveying drainage conduit element designed to be installed in a subterranean room having an outer peripheral wall having a base supported on a footing and having a floor with outer peripheral edges which extend to the base of said wall and cover said footing, said drainage conduit element being designed to be substantially covered by the peripheral edges of said floor of said room, to receive groundwater admitted at said base and through areas of said wall above said base and to convey said groundwater to a remote drain, said drainage conduit element comprising a vertical upper wall portion which is designed to extend above the surface of said floor, adjacent the wall of said room, said vertical upper wall portion having a rear surface comprising uniform spacer means for engagement with the wall of said room to space the rear surface of the vertical upper wall portion from the wall of said room and provide therebetween a narrow drainage space to admit water flowing down the wall of said room, said vertical wall portion extending downwardly and outwardly, away from the vertical, to a horizontal base wall portion designed to engage the wall footing and support the conduit element thereon, said vertical and horizontal wall portions enclosing an elongate conduit section which is open to the admission of groundwater to convey said water peripherally through said drainage conduit element to one or more remote drains.

Abstract
A sub-floor water control drainage conduit element and system which minimizes installation labor, materials and time. The drainage conduit element comprises an elongate conduit section which is somewhat hemispherical or somewhat-rectangular in cross-section and has a flat base on floor wall, and a roof wall and/or sidewall. The floor wall is designed to be supported on the top surface of a footing at the wall-footing interface or in an excavation at the base of a wall. The conduit section is open to admit groundwater, such as from the wall-footing interface, and the element contains an upper vertical wall portion which is designed to extend above the basement floor surface and is spaced from the basement wall to provide a wall drain gap down to the conduit section.

- 1. An elongate water-conveying drainage conduit element designed to be installed in a subterranean room having an outer peripheral wall having a base supported on a footing and having a floor with outer peripheral edges which extend to the base of said wall and cover said footing, said drainage conduit element being designed to be substantially covered by the peripheral edges of said floor of said room, to receive groundwater admitted at said base and through areas of said wall above said base and to convey said groundwater to a remote drain, said drainage conduit element comprising a vertical upper wall portion which is designed to extend above the surface of said floor, adjacent the wall of said room, said vertical upper wall portion having a rear surface comprising uniform spacer means for engagement with the wall of said room to space the rear surface of the vertical upper wall portion from the wall of said room and provide therebetween a narrow drainage space to admit water flowing down the wall of said room, said vertical wall portion extending downwardly and outwardly, away from the vertical, to a horizontal base wall portion designed to engage the wall footing and support the conduit element thereon, said vertical and horizontal wall portions enclosing an elongate conduit section which is open to the admission of groundwater to convey said water peripherally through said drainage conduit element to one or more remote drains.
- 6. An elongate water-conveying drainage conduit element designed to be installed in a subterranean room having an outer peripheral wall having a base and having a floor with outer peripheral edges which extend to the base of said wall, said drainage conduit element being designed to be substantially covered by the peripheral edges of said floor of said room, to receive groundwater admitted at said base and through areas of said wall above said base and to convey said groundwater to a remote drain, said drainage conduit element comprising an elongate tubular conduit section having a roof wall, an inside wall, an outside wall and a horizontal floor wall portion designed to support the drainage conduit element, adjacent the base of the wall of said room, said tubular conduit section inside wall having a lower wall portion which is recessed inwardly to said horizontal floor wall portion to form an exterior water passage when said drainage conduit is supported against the base of the wall of said room, said recessed lower wall portion being provided with a plurality of spaced water-inlet holes to admit groundwater from said exterior water passage into said tubular conduit section, said inside wall also having a vertical upper wall portion which extends above the roof wall of the conduit section for extension above the surface of the floor of said room, adjacent the wall of said room, the rear face of said vertical wall portion comprising uniform spacer means for engagement with the wall of said room to space the rear face of the vertical wall portion from the wall of said room and provide therebetween a narrow drainage space to admit water flowing down the wall of said room into said exterior water passage at the base of the wall of the room and through said spaced water-inlet holes into the tubular conduit section for drainage to a remote drain.
