Description

Electric cart type portable GRP device {PORTABLE GROUNG PENETRATING RADAR APPARATUS OF ELECTRIC CART}

The present invention relates to a portable GPR device of the electric cart type, and more specifically, to a portable GPR device of the electric cart type used to detect the presence of underground cavities in sidewalks as well as roadways.

Recently, road cave-ins and ground subsidence accidents have occurred frequently in urban areas, emerging as a social problem due to loss of life and damage to structures.

Preventative activities are being actively carried out by conducting joint exploration of the cavity under the road surface in the roadway section using Ground Penetrating Radar (GPR) exploration techniques, but joint exploration is not taking place in the sidewalk section.

Joint inspection of sidewalk sections must be conducted by underground facility managers at least once every five years in accordance with the Underground Safety Act. However, due to limitations in environments other than roadways (pedestrians, obstacles on the road, etc.) and joint inspection equipment and technology, safety inspections are limited. The reality is that effectiveness cannot be secured.

Compared to the roadway section, the compaction level of the lower part of the pavement layer in the sidewalk section is low and there are many underground structures, so the underlying ground condition is very complex.

In addition, unlike asphalt or concrete pavement, sidewalk sections have a discontinuous surface layer structure, so if cavities exist, structural stability against collapse may be low even though there is no vehicle load.

However, as cavity occurrence and ground subsidence continue to occur in sidewalk sections, safety accidents for pedestrians are a concern, so there is a need to develop and improve joint exploration technology.

Unlike roadways, sidewalk sections have the disadvantage of being used for a long time due to their low exploration speed.

In particular, the method of manually investigating existing hand-held GPR exploration equipment for joint exploration of sidewalk sections has the disadvantage of taking a lot of time and increasing costs.
