Abstract
A drainage unit for an earth retaining wall system to provide water drainage from a vertical drainage sheet through the retaining wall to reduce hydrostatic pressure on the retaining wall. The drainage unit comprises a drainage collector for attaching to a sheet drain to collect and discharge water that flows into the sheet drain. A drain hub is included in the drainage collector for being mounted in fluid communication with the sheet drain to receive and channel water for discharge. A discharge extension is included in the drainage collector that extends from the drain hub for discharging water through the retaining wall. A retainer is provided for engaging the discharge extension after passing through the sheet drain and securing the drain hub and discharge extension in position on the sheet drain.

A drainage unit for an earth retaining wall system to provide water drainage from a vertical drainage sheet through the retaining wall to reduce hydrostatic pressure on the retaining wall, said drainage unit comprising:
- a drainage collector for attaching to a sheet drain to collect and discharge water that flows into the sheet drain;
- a drain hub included in said drainage collector for being mounted in fluid communication with said sheet drain to receive water from said sheet drain and channel the water for discharge;
- a discharge extension included in said drainage collector extending from said drain hub for discharging water from said sheet drain flowing through said drain hub;
- and
- a retainer having a discharge opening for engaging said discharge extension after passing through said sheet drain and securing said drain hub and discharge extension in position on said sheet drain;
- whereby a drainage unit is provided that is firmly attached to a sheet drain to prevent separation of the drainage unit from the sheet drain during construction of the retaining wall, and which relieves hydrostatic pressure by channeling water from behind the retaining wall through the retaining wall.
A drainage unit for an earth retaining wall system to provide water drainage from a vertical drainage sheet through the retaining wall to reduce hydrostatic pressure on the retaining wall, said drainage unit comprising:
- a drainage collector for being inserted through a sheet drain to collect and channel water that flows into the sheet drain for discharge through the retaining wall;
- a front sealing ring carried by said drainage collector for engaging a front exterior side of said sheet drain to restrict debris from entering the drainage collector;
- a retainer for engaging said drainage collector after passing through said sheet drain and securing said drainage collector in position on said sheet drain;
- and
- a rear sealing ring carried by said retainer for engaging a rear exterior side of said sheet drain to restrict debris from entering the drainage collector;
- whereby a drainage unit is provided that is firmly attached to a sheet drain to prevent separation of the drainage unit from the sheet drain during construction of the retaining wall, and which relieves hydrostatic pressure by channeling water from behind the retaining wall through the retaining wall.
A drainage unit for an earth retaining wall system to provide water drainage from a vertical drainage sheet through the retaining wall to reduce hydrostatic pressure on the retaining wall, said drainage unit comprising:
- a drainage collector for attaching to a sheet drain to collect and discharge water that flows into the sheet drain;
- a drain hub included in said drainage collector to receive water from said sheet drain and channel the water from said sheet drain for discharge;
- a plurality of fluid channels included in said drain hub in fluid communication with said sheet drain for channeling water from the sheet drain into said drain hub.
- a discharge extension extending from said drain hub through the retaining wall for discharging water from said sheet drain flowing through said drain hub;
- and
- a retainer for securing said drain hub and discharge extension in position on said sheet drain;
- whereby a drainage unit is provided that is firmly attached to a sheet drain to prevent separation of the drainage unit from the sheet drain during construction of the retaining wall, and which relieves hydrostatic pressure by channeling water from behind the retaining wall through the retaining wall.
