Precast parapet for elevation.
L-shaped parapet blocks that enable elevation by being installed on top of levees and tidal barriers.
■Early flood prevention measures are possible. ■The impact on the surrounding environment can be minimized. ■It accommodates product heights of 1.1 to 1.5 meters. ■No need for cast-in-place concrete. ■Easy installation, shortened construction period, and labor-saving on-site work can be achieved. ■A shape is adopted that sets the backfill height low to minimize the impact on existing structures. ■It has a strong integrity with three reinforced fittings. ■Waterproofing between products is ensured by sealing materials.
basic information
【Design Conditions】 Soil pressure calculation method: Trial wedge method Unit weight of reinforced concrete: γc = 24.5 kN/m³ Unit weight of soil: γs = 19.0 kN/m³ Unit weight of water: γw = 9.8 kN/m³ Internal friction angle of soil: φ = 30° Overburden load: Q = 10.0 kN/m² Impact load and action position: The effects of impact loads can also be examined, so please contact us. Friction coefficient for sliding: μ = 0.6 Normal conditions During impact and flooding Design standard strength of concrete σck = 40 N/mm² Allowable bending compressive stress of concrete σca = 14 N/mm² 21 N/mm² Allowable tensile stress of rebar (SD295) σsa = 160 N/mm² 270 N/mm² *The effects of water pressure and buoyancy can also be examined, so please contact us.
