確に阻止することができる。For this reason, the posture of each shutter plate 10 is appropriately switched by the movement of the operating portion 18a of the switching member 18, and the frame 1 and the ventilation hole are opened to allow ventilation in the underground cavern, and the frame 1. It is possible to automatically switch to the state where the inflow of water into the underground cavern is blocked by closing the inside and ventilation holes, and even if an abnormal water outflow occurs, each shutter plate will prevent the intrusion of muddy water into the underground cavern. It can be accurately stopped by 10.

Switching member 1 that functions as a drive source for driving 0
Since 8 functions as a sensor for detecting the drive timing of each shutter plate 10, a drive source such as electricity or pneumatic pressure and sensors for detecting abnormal water discharge are unnecessary, and power consumption, wiring work, and piping work are unnecessary. In addition, the switching mechanism for switching the posture of each shutter plate 10 can be simplified to reduce the cost.

とを特徴とする地下洞道用グレーチング。1. A frame-shaped water receiving trough that receives water in a frame that is installed at an upper end of a ventilation hole that connects the inside of an underground cavern and the ground and has a lattice lid fitted therein, and a bottom of the water receiving trough. A plurality of shutter plates, which form open water collecting ports, are supported in the frame so that they can be tilted up and down, and are arranged in parallel with a gap therebetween, and are linked to the shutter plates so as to be interlocked with each other. And a transmission member that moves in the arrangement direction of the shutter plates to convert the postures of the respective shutter plates into the postures in which the gaps are opened and the postures in which the gaps are closed, and swings below the water collecting port. The switching member, which is installed so that it can be interlocked with the transmission member, has an operating portion having a water reservoir tank into which the water collected at the water collecting port flows, and the water reservoir tank is provided with the water reservoir tank. A small amount of water flowing into the tank Grating for underground cavern characterized by forming water discharge holes that discharge in quantity.
