Geobag block using recycled aggregates in gravity retaining wall systems and the construction method with the geobag block

摘要

A geobag block using recycled aggregates in a gravity retaining wall system and a method for constructing the gravity retaining wall system by using geobag are provided to recycle construction wastes by employing recycled aggregates for the gravity retaining wall. A geobag block(2) has a hexahedron shape and a volume above 1 cubic meters. The geobag block(2) includes polypropylene. The friction angle of geobag blocks(2) is in the range of 45 degrees to 60 degrees. Recycled aggregates (waste concrete + waste ASCON)(3), having the maximum diameter of 100mm, are filled in the geobag block. A retaining wall having the height of 5mm or less is constructed by employing a recycled aggregate having particle size of 40mm or less and a friction angle in the range of 45 degrees to 60 degrees.
