Home Profile Products Services Contact Since 1958 P495-P517 MARINE CORP AIR STATION QUANTICO (MCAS) AIRFIELD APRON AND HANGER A combination of slotted drains (6500ft.) were used to capture the sheet flow on the large concrete paved apron. The slotted drains were pre-sloped and designed to handel military airlift loading requirements. A slotted drain has a minimal surface exposure (1.75" wide), but a large capacity for fluids, and no grate to be concerned with. The US Navy requires a AFFF system to be installed in all the floors of their hangers. The 18" wide grated trench drain works as a collector of the fire suppresion foam that is piped in the same trench. A special nozzel grate dispences the foam from floor to cealing in seconds. APM TERMINAL - PORTSMOUTH, VA This port terminal project utilized 10,000ft of a pre-manufactured 18" wide Class F load rated trench drain, designed to the clients dynamic loading and flow specifications. The original design called for the contractor to purchase a frame & grate, form the trench and cast in place. The pre-manufactured product allowed the contractor to quickly assemble 20ft-40ft sections and set into their form work. A pre-manufactured drain eliminated requirement for wrecking of the internal forms, complicated sloped forms, or concrete patching. These factors allowed the contractor to quickly and cost effectivly complete this portion of the project. RICHMOND AIRPORT (RIC) ARRIVALS AND DEPARTERS ELEVATED ROAD Richmond airport made a major expansion which required 2500ft of a 10" wide trench drain. The drain had to meet certain design parameters, ADA heel proof compliant traffic rated grate, pre-sloped, able to recieve side inlets from elevated road drains, and follow the curb profile. The modular design and long channel sections allowed the contractor to meet their required completion time table. RICHMOND AIRPORT (RIC) DE-ICING PAD IMPROVEMENTS AND EXPANSION Due to increased volume of activity on the airside of RIC the existing 1800ft deicing collector trench drain needed to be replaced and lengthend. The original drain frame suffered from the constant aircraft dynamic loading causing it to fail. The airport designer elected to use a more robust frame and grate which exceeded the FAA load requirements. The chemical resistance of the drain material was a requirement due nature of the deicing fluid that would be intercepted by the drain. Projects WATERMILL CROSSING A large open bottom multi-plate structure was used to cross a stream in this Chesterfield County subdivision. The open bottom allows the natural stream bed not be disturbed and the plate structures are mounted to a engineered footing. THE VILLAGE A Henrico County development required a volume of storm water to be stored on site for a certain duration. A 500ft 48" CMP detention system was installed in a double barrel design that followed the contours of the curb. All connections were gasketed, inlets/outlets pre attached, and all of the fittings pre-manufactured & ready for insttaltion. © 2023 by Lion Heavy Gear. Proudly made by Wix.com
