On the other hand, as shown in FIG. 9, when the inside of the manhole (not shown) is gradually submerged due to intensive rain or water from the outside, the case 10 is floated due to the increased water level, 62).

When the case 10 is lifted up, the detection sensor 70 detects the underground distribution line L installed in the case 10 and continuously outputs the detection signal. And outputs a flood warning signal if it is longer than the predetermined signal input time.

The transmitter 90 installed in the guide angle 62 receives the flood warning signal from the control unit 80 and transmits the flood warning signal to the outside (management room in which the administrator resides). Upon receiving the flood warning signal, So that the subsequent work can be performed quickly.

According to this embodiment, when an external force is applied to the underground distribution line L, the platform 60 is moved along the upper surface of the fixing plate 50 in the direction in which the external force acts, It is possible to minimize the impact applied to the connecting portion of the connecting member 100 and to prevent the damage.
