Sewer mounting pipe cavity investigation machine
Road's caving has very high risk of serious accidents of suddenly engulfing pedestrians and cars, etc. In Tokyo area, annually there are more than 1000 road caving cases due to sewage pipes, most of which is due to the mounting pipes connecting the main pipes and the households'. This device has a camera attached to the transmiting and receiving antena, confirming the status in the pipes as well as and use electromagnetic wave checking the cavity arround the pipes.
■Simultaneous exploration can be done with integrated system of TV camera and electromagnetic wave radar
■It is possible to confirm the cavity position, etc from the pipe mouth with the distance measuring function
■It is possble to confirm the overall size of the cavity and its distance with the pipe
■Radar images can be directly processed by the computer and put in the database
