<p>A new type of plastic ground mat comprises a rectangular ground mat body (10) provided with two strip-shaped extending side portions (11, 12) on two contiguous sides of the rectangular body. Outer ends of the two extending side portions are provided with two joint portions (41, 42). Two recess side portions (13, 14) matching with the two extending side portions are set on the other two contiguous sides of the rectangular body. Inner ends of the two recess side portions are provided with two jointed portions (43, 44) corresponding to the two joint portions. Two contiguous ground mat bodies are joined and fixed with each other by the interaction of the joint portion and the jointed portion. The plastic ground mat can be conveniently assembled, and can avoid the permeation of water and other impurities.</p> |
