titleOfInvention | Water blocking room for shield tunnel entrance |
abstract | An object of the present invention is to prevent outflow of earth and sand or water generated in a tunnel into a shaft while the tip of a shield machine reaches the position of a seal member at a tunnel opening. A removable chamber 5 is connected to the outside of a cylindrical member 4 provided at a shield tunnel port in a shaft 1 and covering the periphery with a size capable of accommodating a shield machine 2 extracted from the tunnel port. Thus, sediment such as earth and sand flowing out from the tunnel opening while the tip of the shield machine 2 reaches the position of the rubber packing 6 attached to the cylindrical member 4 is accumulated in the chamber 5, and these are stored in the shaft 1. Was prevented from flowing into. [Selection] Figure 1 |
