PERMEABLE ELASTIC FLOOR STRUCTURE, SUPPLYING SUFFICIENT MOISTURE TO PLANTS AND NUTRIMENT TO PLANTS VIA GRANULAR SILICIC ACID AND CALCIUM CARBONATE

摘要

PURPOSE: A permeable elastic floor structure is provided to supply nutriment to plants via granular silicic acid, to ensure constructability, to improve work efficiency, to reduce cost and time by omitting primer covering. CONSTITUTION: A permeable elastic floor structure is formed on a cut site(1) formed by cutting the ground in predetermined depth and leveling the cut ground. The permeable elastic floor structure comprises a lower layer part(10) and an outer layer part(20). The lower layer part is formed to the top of the cut site. Fine aggregate(11) of fine gravel or waste construction material chips is joined to each other by a binder including at least one of granular silicic acid and calcium carbonate and the lower layer part is formed. The lower layer part comprises 70¯90 weight percent of fine aggregate with grain size of 5¯50 mm and 5¯10 weight percent of the binder. The outer layer part is fixed to the top of the lower layer part. Urethane chips(21) are joined to each other by a binder including at least one of granular silicic acid and calcium carbonate and the outer layer part is formed. The outer layer part comprises 70¯90 weight percent of urethane chips with grain size of 1¯5 mm and 10¯20 weight percent of the binder.
