Detailed Description of the Invention and Field of Industrial Application] This invention is a method for exploring the thickness of unreinforced concrete wrapped as a tunnel lining and the cavities of the ground behind it. This invention relates to tunnel inspection equipment.
一般に、トンネルの内壁は無筋コンクリートで覆われ、
地山の崩壊がおこらないようにしている。Generally, the inner walls of tunnels are covered with unreinforced concrete.
This prevents the collapse of the ground.

。However, in the past, the concrete surface was visually monitored, and when an abnormality was found, drilling was performed to check the thickness of the concrete at that point and whether there were any cavities behind it. It has the disadvantage that it is inefficient and that countermeasures cannot be taken until after the concrete IJ+ has deteriorated.

クリート表面の状態がビデオデツキ７に記録される。The trolley 2 accurately detects the direction of the eyes and head using the direction control sensor 11, and travels while being controlled by the steering controller 1-a-ra 12 so as to travel in that direction. During this run, information on the cross-sectional direction of the concrete is recorded on the data recorder 6 by radio waves transmitted and received from the underground radar device 5 via the antenna 3, and the condition of the concrete surface at that point is recorded on the video deck 7. recorded.
このときそれぞれの記録データの同期をとるための同期
パルスが同期パルサ８によって加えられる。At this time, a synchronization pulse is applied by the synchronization pulser 8 to synchronize each recorded data.
また、データレコーダ６にはロータリエンコーダ９から
走行地点の位置情報を表わす信号が加えられる。Further, a signal representing positional information of a traveling point is applied to the data recorder 6 from a rotary encoder 9.

後で見ながら補修の時期を検討することができる。These images are synchronized by a synchronization pulse, so that the images at the same point, that is, the cross-sectional portion corresponding to the concrete surface, are completely synchronized. Since these data are recorded, they can be reproduced at any time and any number of times, and the timing of repairs can be considered by looking at the reed, surface and cross-sectional conditions later.

ようにし、ておく。It is desirable for the antenna 3 to slide on the concrete surface, but since it will wear out due to running, wheels 3a and 3b are attached as shown in Figure 4 to ensure smooth sliding.
It is also desirable to press the pantograph 3c against the concrete surface with moderate pressure. At this time, the arm 3d is made expandable and retractable so that it can respond to changes in the diameter of the tunnel.
＠５図は車輪を用いず、エアを吹きつけることによって
所定の間隔を保つようにした例である。Figure @5 is an example in which a predetermined distance is maintained by blowing air without using wheels.
