EXPANDABLE MAT FOR EMERGENCY RESTORATION OF GROUND SUBSIDENCE

摘要

The present invention relates to an expandable mat for the emergency restoration of ground subsidence and, more specifically, relates to an expandable mat for the emergency restoration of ground subsidence, capable of stiffening an expanding agent (cutback asphalt) with predetermined strength and hardness by having a side expanded with a predetermined thickness through the expanding agent to fill a pothole if the expanding agent is injected into the expandable mat after the expandable mat is inserted into the pothole. The present invention comprises: first and second cover units made of a flexible but non-expandable material and installed to face each other; a connecting member connecting the first and second cover units while keeping a predetermined gap therebetween; an injecting means formed on one of the first and second cover units to inject an expanding agent; and a lateral means having a tip connected to the first and second cover units, and closing separated sides of the first and second cover units.;COPYRIGHT KIPO 2019
