SUPPORT MEMBER OR REINFORCEMENT FOR USE IN EARTHWORKS

摘要

A rigid plastics tray (100) has a planar base (102), an outer periphery (104) and internal walls (106) that form compartments on the base. The tray is used in the substructure of pavements and the like, e.g. in lieu of hardcore or other sub-base material. In use, the tray can be placed on a ground surface with its base uppermost, wherein an upper layer of paving (112,114,116) can be supported by the tray. The tray can also be used with its base lowermost, wherein the tray is used to contain fill material, typically below ground level, e.g. for use as a soakaway. The tray may include drainage apertures in its base and service apertures in the internal walls for passing service cables and conduits through the tray.
