NEGATIVE PRESSURE WAVE GENERATOR
PROBLEM TO BE SOLVED: To provide a negative pressure wave generator which can effectively reduce a micro barometric wave.SOLUTION: A negative pressure wave generator 1 reduces the pressure of a micro barometric wave radiated from a mine mouth 21 of a tunnel 2 by means of a negative pressure wave, and includes a vacuum container 11 which is arranged in the vicinity of the mine mouth 21 and adjacent to a rail 31 on which a train 3 travels or between a plurality of laid rails 31 and which can be brought into a vacuum state inside thereof, and a first opening 12 provided in a side of a generation source Cof the micro barometric wave in the vacuum container 11, and a valve body 13 which can open and close the first opening 12.SELECTED DRAWING: Figure 1
【課題】微気圧波を効果的に低減することができる負圧波発生装置を提供する。【解決手段】トンネル２の坑口２１から放射される微気圧波の圧力を負圧波によって低減する負圧波発生装置１であって、前記坑口２１の近傍であって、列車３が走行するレール３１の脇または複数敷設される前記レール３１の間に配置され、内部が真空状態となり得る真空容器１１と、前記真空容器１１における前記微気圧波の発信源Ｃ21の側に設けられる第一開口部１２と、前記第一開口部１２を開閉可能な弁体１３とを備えて成る。【選択図】図１
