Since the inside of the manhole is higher than the outside temperature due to domestic wastewater, only the snow and ice above it melts, creating a large hole in the road surface. Sometimes the hole can be more than 30cm deep, which is a big problem in snowy areas, such as obstruction of traffic, traffic jams, and injuries to pedestrians, but no solution has been made until now. There was no. The present invention is to solve those problems. [0004] The temperature of the inside of a manhole and the outside air is shut off, so that only snow and ice on the manhole are prevented from melting, so that there is no unevenness on the road surface. This problem can be solved by installing a heat insulating device under a conventional manhole cover in order to shut off the temperature of the inside of the manhole and the outside air. This will be described with reference to the drawings. (1) is a heat insulating material (2) is a heat insulating material holding bracket (3) is a conventional manhole (4) is a manhole cover (5) is a road surface (6) is a snow and ice insulating material on a road surface ( 1) is combined with the heat insulating material holding bracket (2) to obtain the manhole heat insulating device of the present invention. The manhole insulation device is placed in the manhole (3) which has been conventionally installed, and the manhole cover (4) is placed thereon. [0004] The installed manhole heat insulating device cuts off the temperature of the inside of the manhole and the outside air, and prevents only the snow and ice (6) on the manhole from melting and forming a large hole on the road surface. Further, since the thickness of the heat insulating material holding bracket (2) is negligible with respect to the unevenness of the road surface, it can be easily installed without changing conventional equipment.
