摘要

The ground (10) has a needled type moquette with rot-proof synthetic fibers (16) fixed to a backrest (18), where the synthetic fibers are made of polypropylene. The synthetic fibers are fixed to the backrest such that a buckled moquette (12) is formed. The moquette is filled with crushed rock (14), where overthickness (20) of the rock is 2-5 millimeter. Mass of the synthetic fibers is approximately 400 grams >meter 2>, and mass of the moquette without the rock is approximately 1500 grams >meter 2>.
