  • Highway underdrain plastic apron endwall with anti-floatation wings
    Patent number: 6394700
    Abstract: A plastic apron endwall is connected to a drain which extends under a highway. The apron endwall is in the form of an upwardly opening trough having a general wedge shape and incorporates lateral wings which extend outwardly from the sides of the apron end wall into the surrounding soil, so that as installed, the soil overburden prevents the apron end wall from being displaced upwardly by buoyancy forces in the event that the ditch into which the apron end wall drains becomes flooded. The total planar area of the wings is selected so that the overburden, that is the soil which lies above the wings, is sufficient to offset any buoyancy force produced by water saturated the soil in which the apron end wall is embedded.
