초록

A modular structure for supporting weight loads and traffic in extensively used turfgrass areas comprising a plurality of identical modules having open cells defined by vertical wall portions and a bottom wall. The modules are disposed in laterally adjacent interengaging interlocked relation to form the modular structure which is imbedded in the turfgrass area to a depth slightly less than the height of the module cells so that the upper edge portions of the cell side walls extend into the turfgrass to support and bear the weight and wear of traffic pass...
