GRP device with up and down and left and right movement {PORTABLE GROUNG PENETRATING RADAR APPARATUS WITH UP, DOWN, LEFT AND RIGHT MOVING FUNCTION}

The present invention relates to a GPR device having up and down and left and right movement functions, and more particularly, in GPR exploration of a road with a wider width than a vehicle, according to the moving direction of the vehicle, including the left and right areas of the vehicle, there is no blind spot. It relates to a GPR device equipped with vertical and horizontal movement functions enabling accurate exploration.

Recently, damage from sink-holes and road collapses frequently occurs in downtown areas across the country, causing social unrest.

The main causes of sinkholes and road collapses are aging and damage of urban infrastructure such as underground facilities, poor backfilling of structures, and soil loss from the ground, such as poor construction.

Therefore, efforts are required to maintain the safety and function of the road environment.

From the above point of view, GPR (Ground Penetrating Radar) exploration is widely used in Korea for the advance prediction and prevention of risk factors in invisible underground spaces.

GPR exploration is the most suitable exploration method for detecting buried objects and cavities in the ceiling, and its use is rapidly increasing.

The configuration of vehicle-type GPR equipment for road exploration is essential, and an effective method for imaging the shallow underground is required.

The antenna of the GPR survey consists of a transmission antenna that emits electromagnetic waves, a multiple antenna combined with a reception antenna that receives electromagnetic waves that have undergone reflection, refraction, and diffraction in the underground medium, and a recording device that records and controls data. there is.

In order to explore the road surface, it must be able to accurately explore at a speed that does not interfere with traffic flow, and it is necessary to respond flexibly to the road situation when measuring.

Existing vehicle-type GPR surveys had the disadvantage of requiring a lot of manpower and time, such as manpower assembly of the GPR antenna and vehicle towing installation.
