Design Consideration

The structure design of Precast RC Box Culvert is in accordance with the requirement of:

BS 5400 : Part 4 : 1990
BD 31/01 The Design of Buried Concrete Box and Portal Frame Structures
MS 1293 : Part 1 : 1992

Box culverts are able to withstand a standard 2m (Max.) of superimposed backfill depth and 45 units of HB vehicle live load.
Standard size box culverts also comply with proof load test of 112.5 kN over an area of 320mm x 320mm placed at any position on the box culvert's lid.
Minimum backfill depth of 600mm over box culverts are recommended to avoid undesirable direct impact load.
Hydrostatic pressure is eliminated by provision of weepholes placed along the centerline of the invert wall.

Types

Standard Size Box Culvert (width from 300mm to 1800mm)
