The invention belongs to the technical field of mechanical devices, and relates to micro-pressure waves of a high-speed railway tunnel, in particular to a relieving system for secondary micro-pressure waves of the high-speed railway tunnel, which comprises the high-speed railway tunnel (1), and a vertical shaft (3) communicated with the outside is arranged on the inner top surface of the high-speed railway tunnel (1) along the advancing direction of a train; the structure is characterized in that an open space (17) with the width 1.1-1.2 times of the diameter of the vertical shaft is excavated at the top in the high-speed railway tunnel (1) and in front of the vertical shaft (3) in a penetrating manner, and the inner top surface of the open space (17) is 0.8-1.5 m higher than the top point of the top surface of the high-speed railway tunnel (1). The device is reasonable in design, aims to prevent the secondary micro-pressure wave phenomenon generated when a train passes through the vertical shaft while the inhibition effect of the tunnel vertical shaft on the primary micro-pressure wave is not influenced, and has very good practical application value.
本发明属于机械装置技术领域,涉及高速铁路隧道的微气压波,具体为一种高速铁路隧道二次微气压波的缓解系统,包括高速铁路隧道(1),所述高速铁路隧道(1)内顶面沿列车行进方向上设置有与外界相通的竖井(3);其特征在于:所述高速铁路隧道(1)内顶部位于竖井(3)及其前方贯通开挖一个宽度为竖井直径1.1~1.2倍的开部空间(17),所述开部空间(17)内顶面高于高速铁路隧道(1)顶面顶点0.8~1.5m。本发明设计合理,旨在不影响隧道竖井对一次微气压波抑制作用的同时,阻止列车通过竖井时产生的二次微气压波现象,具体很好的实际应用价值。
