The invention discloses a tunnel portal compression wave reducing device capable of preventing falling rocks. The tunnel portal compression wave reducing device comprises a plurality of louver blades and a first protective net, wherein the louver blades are fixed to a mountain tunnel portal, a first height is set between the louver blades and the ground, and the first protective net is arranged between every two adjacent louver blades. The tunnel portal compression wave reducing device is arranged at the tunnel portal, the outer diameters of the louver blades are gradually reduced until the louver blades are as large as the tunnel portal, by means of the principle of enlarging the opening of a tunnel, airflow is quickly discharged by utilizing the structures of the louver blades, and compression waves can be effectively reduced; and in addition, the first protective net and a second protective net are arranged, energy consumption of the falling rocks is blocked, and the safety is improved.
本发明公开了一种防落石的隧道口压缩波减小装置，包括固定在山体隧道口的多个百叶片和第一防护网，多个所述百叶片与地面之间设置第一高度，所述第一防护网设置在相邻两个所述百叶片之间。本装置设置于隧道口，百叶片的外径由大变小，直至与隧道口一样大，通过扩大隧道的开口原理，同时利用百叶片的结构快速排放气流，能够有效的减小压缩波，另外设置第一防护网和第二防护网，对落石进行格挡耗能，增加了安全性。
