Title:
TUNNEL
Document Type and Number:
Japanese Patent JP2015183383
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance the compressive wave reduction effect at a low cost.SOLUTION: A tunnel 10 for making a train travel comprises a cylindrical lining body 11 for forming an outer shell of the tunnel 10, a partition wall 20 provided in the lining body 11 and partitioning the inside of the lining body 11 into a train travel space S and a resonator forming space R and a plurality of opening parts 31 formed at an interval in the axial direction of the lining body 11 on the partition wall 20 and communicating the resonator forming space R with the train travel space S side. The opening parts 31 and the resonator forming space R reduce a compressive wave generated when the train travels in the train travel space S.
