First, with the first sluice valve 2 of the existing pipe 1 closed, the air valve 2Vc, which is normally provided with the first sluice valve 2Vc, is removed, and then the flange 3 is attached. At this time, the existing pipe 1
If there is no gate valve, install a gate valve of 50% or more in the uninterrupted water branch construction method, and then install a second gate valve at the base of survey pipe 4.
After installing the gate valve 9 in the closed state, move the first gate valve 4 to the predetermined position while opening the first gate valve 2.
Push it inside. Then, the guide roller box 10 with the television camera 7 and lighting device @8 arranged at the guide roller 110 position is attached to the second gate valve 9. Next, the second gate valve 9 is opened, the underwater cable drum 13 is rotated, and the cape/L/6 is guided by the guide rollers 11 and let out V'c inside the existing pipe 1.

Therefore, by observing the inside of the existing pipe 1 as a TV image, it is possible to accurately grasp the internal state of the existing pipe 1, and the distance of the cape (V5) extended to 1 circle of the existing pipe can be added to 1 offshore. Therefore, the location of the abnormality in the existing pipe 1 yen photographed by the television camera 7 can be specifically located. Moreover, since the above-mentioned work can be carried out in a friendly manner by passing water into the existing pipe 1, it is possible to have f yen as a side dish without stopping the supply to the lower pickled side. After setting and completing the lA inspection, move the cape/l/6 from the underwater cable drum 131C to the guide roller IIK.
Wind it around while guiding it, causing damage to the television camera 7.
