Fabricate the grate assembly from structural steel in accordance with Section 501, Structural Steel. The department does not require shop inspection or drawings. Galvanize the grate in accordance with Subsection 501.4.1.25, Galvanizing. 631.4.2 Installation
Do not install slotted drains in sidewalk curb ramps or pedestrian paths. Excavate in accordance with Subsection 206.4.1, Excavation.
2 Use watertight pipe coupling bands and end plugs. Use rubber gaskets with the coupling
bands to ensure water-tightness. Use a metal or concrete end plug that matches the pipe corrugations. 3 For end plugs and for concrete used as backfill around slotted drains, use class B
concrete in accordance with Subsection 513.4.4, Mix Design. The engineer may approve a local commercial mix. The department does not require a cement sample or aggregate gradation tests. 4 Use class B bedding material or concrete for the pipe bed.
Use concrete for the top portion of the trench immediately above the bedding, as specified. When constructing a concrete pipe bed, prevent floating of the pipe. 5 When placing curb or paving material over slotted drains, cover the opening to keep
out foreign material. Do not extend the slot above the paving material or gutter section. 631.4.3 Repair of Damaged Coating 1 Repair damage to spelter coatings in accordance with Subsection 501.4.2.9, Repair
of Galvanizing. Do not backfill the pipe before inspection and approval of repairs by the engineer.
