RAPID CONSTRUCTION METHOD FOR RESTORING SLAB SUBSIDENCE AS WELL AS REINFORCING ROADBED IN EARTHWORK CONNECTION PART OF ROAD OR RAILWAY TRACK AND EQUIPMENT THEREOF

摘要

According to the present invention, provided are a rapid construction method for restoring slab subsidence as well as reinforcing a roadbed in an earthwork connection part of a road or railway track and equipment thereof. A roadbed is reinforced to increase rigidity against an impact load delivery area in an earthwork connection part in which an earthwork and a structure such as a bridge, a tunnel or the like are connected. Since a space between the roadbed and the lower part of a slab of a concrete track or road is filled with a filling material, the road or railway track can be restored to an original height which was applied before the subsidence of the slab. Moreover, since the restoration of existing slab subsidence and the reinforcement of a lower roadbed which is a cause for the subsidence of the road or railway track are rapidly performed at the same time, time for traffic suspension can be minimized, and also, subsidence correction construction which needs to be repetitively performed due to subsidence arising during a performance period can be finalized with construction performed only once.;COPYRIGHT KIPO 2020
