摘要
The present invention relates to a method for manufacturing a joint packing sheet for a connection joint connecting a prefabricated concrete tunnel object manufactured on the secondary ground to the inside the primary submarine excavation tunnel and a 40-60m deep underground tunnel in the primary tunnel site. A wasted tire is mixed with ethylene-vinyl-acetate 30 parts by weight containing an emulsifying agent with respect to rubber powder ground by 30-50 mesh 100 parts by weight to be applied on both sides of a non-woven fabric to manufacture a connection joint packing sheet having a thickness of 10mm.;COPYRIGHT KIPO 2015
