グに関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used as a cover for a ventilation port provided by burying an electric wire, a gas pipe or the like or in an underground space for a subway or the like, and normally maintains a ventilation function. However, the present invention relates to a waterproof grating which can prevent rainwater and the like from entering the underground space during heavy rainfall.

諸設備に多大な被害を与えるおそれがある。2. Description of the Related Art Ventilation openings for ventilating an underground space as described above are usually installed on sidewalks of roads. Flood control measures for the underground space are currently performed assuming a certain amount of rainfall, and if there is more rainfall than this, there is a risk that it will overflow from the road and be flooded from the ventilation port. If it is a small-scale inundation, it can be drained by the drainage device installed in the underground space, but it cannot cope with a large-scale inundation, and there is a possibility that various facilities in the underground space will be damaged greatly.

嚢による防水処理では、必ずしも充分ではなく、水流が

それがある。For this reason, a sandbag is prepared near the ventilation port, and when large-scale inundation is expected, the periphery of the opening of the ventilation port is surrounded by the sandbag to prevent inundation. However, waterproofing with sandbags is not always sufficient, and there is a possibility that it will be almost useless if the water flow becomes strong or the amount of water increases.

るものである。Further, conventionally, it is known to install a ventilation port waterproof device for directly blocking the ventilation port. An example of such a waterproof device is, for example, Japanese Patent Laid-Open No. 11-3010.
There is one disclosed in Japanese Patent No. 0. That is, this waterproof device is arranged at the upper end opening of the ventilation opening of the underground space,
A casing having an openable and closable valve body for preventing infiltration of rainwater and the like, and an operating member for opening and closing the valve body are arranged below a grating made of a grid-shaped metal strip or the like. .

The structure is such that the valve body is opened and closed by a screw rod that moves the link up and down.

６０％程度に換気口を防水することができればよいとさ
れている。By the way, the above conventional techniques have the following problems to be solved. Usually, a pumping pump is installed in the underground space assuming a certain amount of rainfall. And, even if rainwater enters the underground space due to heavy rainfall, it is said that it is enough that the ventilation port can be waterproofed to about 60% as a standard not to exceed the amount of water that can be pumped to the ground by the pump. There is.

の分、製作費用が嵩むという難点がある。However, the above-mentioned conventional ventilation port waterproofing device is constructed separately from the grating, and has a robust structure and an excellent waterproofing effect. There is a drawback that the structure is large and there is a spare capacity, and the manufacturing cost increases accordingly.
