PURPOSE: To prevent the sinking of the ground generated by the driving force of tires in case of the starting and stopping of cars by a method wherein a reclaimed land is levelled, a gauze is laid, and the gauze is mounted to the ground by studs.

CONSTITUTION: A reclaimed ground 1 is first levelled, and a gauze 2 is lain on the surface. The gauze 2 is formed in about 50mm each space l by a steel wire with a diameter such as about 4mm. The gauze 2 is laid on the ground 1, and forked studs 3 with approximately 300mm are driven into the ground 1, holding the steel wire at proper locations at the crossing sections of each steel wire of the gauze 2. Thus, the gauze 2 can be mounted onto the ground 1, and the sinking of the ground generated by the driving force of tires can be prevented.
