Inlets, Manholes, and Junction Boxes are key elements
of storm water drainage control systems. These items are typically
designed to withstand AASHTO highway traffic, aircraft traffic,
or other specialty load standards, and are produced to accommodate
any size of reinforced concrete pipe (RCP), corrugated metal pipe
(CMP) or plastic pipe.
|
| Structures are typically built as a monolithic base and wall section, with separate precast top. Where depth exceeds transportation limitations, or where weight exceeds field lifting capabilities, structures may be built with separate riser sections with sealed joints. | ||||
| Structures are often furnished with 4" or 6" PVC pipe connectors for roadway pavement underdrain or edgedrain, and are typically fitted with access steps, cast iron rings and covers and/or galvanized steel grates, as required. | ||||
