The present invention relates to a high-frequency ground penetrating radar (GPR) investigating device for bridge deck pavement condition investigation, consisting of a structure where a first unit, connected to a third unit which is pivotally coupled to a second unit fixed to an installation bracket protruding from the rear end of a chassis where the vehicle's rear wheel is mounted, performs GPR investigation or can be elevated towards the installation bracket side by the operation of the hydraulic pressure of an expansion mechanism of the second unit, allowing for normal vehicle driving with the relatively simple construction of elevating the GPR device to avoid interference with vehicle movement and lowering the GPR device for smooth, rapid, and accurate exploration during the investigation of the condition of bridge deck pavement.

    본 발명은 차량의 후방 휠이 장착된 섀시의 후단부로부터 돌출 형성되는 설치 브라켓에 고정 설치된 제2 유닛에 대하여 회동 가능하게 결합된 제3 유닛과 연결된 제1 유닛이 GPR 탐사를 수행하거나 제2 유닛의 신축수단의 유체압 작동에 의하여 제1 유닛을 설치 브라켓측으로 상승시켜 차량의 일반적인 주행도 가능케 하는 구조로부터, 비교적 간단한 구성으로 GPR 장치를 상승시켜 차량 주행시엔 차량의 주행에 지장이 없도록 하고 GPR 장치를 하강시켜 교면포장(bridge deck pavement) 상태 조사시엔 원활하고 신속하며 정확한 탐사가 이루어질 수 있도록 한 교면포장 상태 조사용 고주파 GPR 탐사 장치에 관한 것이다.
