Slot Drain Detail
Slotted Drain for Drainage. Slotted Drain is a continuous opening inlet that efficiently removes surface water on streets and highways. The grate on a standard 20-foot length of Slotted Drain will intercept up to 50% more runoff than most standard 2’ x 2’ grate inlets. Below are links to trench drain details and slot drain details. You can find the trench drain drawings in CAD, REVIT, and PDF formats. The CSI specification tool is also below and to the right available in Word format for easy editing. Please let us know if you have trouble finding the trench drain or slot drain details that you need and one of. Slotted Drain is a unique pipe which removes sheet flow without multiple grades or water channeling devices. The pipe is cut along a longitudinal axis, and a trapezoidal or straight-sided grate with reinforcing spacer plates is welded to form a 1 3/4 -inch-wide slot opening. This specification describes 4- through 36-inch (100 to 900 mm) ADS DURASLOT pipe for use in surface drain applications. Pipe Requirements DURASLOT pipe, as manufactured and distributed by ADS, Inc., shall have a smooth interior and annular exterior corrugations with an aluminum slot grate frame mounted longitudinally along the length of the. It is a cost-effective substitute for corrugated steel slotted drains, precast trench drains, or cast-in-place trench drains with steel or cast iron grates. Duraslot drains use HDPE pipe, manufactured by Hancor. An outer corrugated wall provides strength and durability, while the smooth interior lining gives exceptional hydraulics. PHySical DetailS.
Slotted Drain Pipe is a practical, aesthetically pleasing drainage inlet product for the efficient removal of surface water and sheet flow on streets and highways. It also is widely used in parking lots and similar locations to remove sheet flow without complex multiple grades, catch basins, or water channeling devices.
Slotted Drain Pipe is fabricated by welding a narrow section of grating in a continuous slot cut in the top of a corrugated steel pipe. A trapezoidal or straight-sided grate with reinforcing spacer plates is welded in place to form a 1 3/4″-wide slot opening which collects runoff and channels it to the pipe below to form a continuous grate inlet.
The benefits of slotted drain pipe include:
- Efficiently removes surface water
- Design improves hydraulic efficiency and provides for easier maintenance
- Wide variety of applications
- Curb inlets
- Airport aprons, taxiways, hangars and de-icing areas
- Railroad and intermodal facilities with heavy axle loads
- Shoulder and median barrier drains
- Inlet system across driveways
- Pedestrian thoroughfares, malls and bicycle paths
- Ground-level floors with drainage requirements
- Parking lots and other continuous paved surfaces
- Sidelines of playing fields and stadiums
