Embodiment Construction
[0081] The pavement structure and construction method of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0082] see figure 1 , the geocell reinforced cement concrete pavement structure of the present embodiment comprises a base layer 3, a surface layer 2 and a wearing layer 1 laid sequentially from bottom to top, figure 1Middle 4 is the subgrade. The base layer 3 is a graded crushed stone layer 8 reinforced with geotextiles 7 of the upper and lower layers and the geocell 9 in the middle; the surface layer 2 is a cement concrete layer 6 reinforced with the geocell 9; Layer 1 is cement mixture wearing layer 11 and geogrid 5 . see figure 2 , the geocell 9 is left with pull rings 10 on both sides along the road direction, the geocell 9 is stretched to a tensioned state, and the outermost geocell 9 is fixed through the pull ring 10 with a wooden wedge 11 .
[0083] The construction method of the above-menti...
