Abstract

The invention discloses a tunnel pressure suppression device. The tunnel pressure suppression device comprises an assembling plate mounted in a tunnel. A longitudinally-arranged suction cavity is formed in the assembling plate. Ventilation pipelines communicated with the outside are correspondingly arranged at the two ends of the suction cavity. Magnet columns are fixedly connected into the two ends of the suction cavity. Apertures communicated with the ventilation pipelines are formed in the middles of the magnet columns. Excitation coils are wound around the magnet columns. Magnet plates aresymmetrically and slidably connected in the suction cavity. A plurality of ventilation openings are formed in the assembling plate at equal intervals. A first mounting groove and a second mounting groove are correspondingly formed in two sides of each ventilation opening. According to the tunnel pressure suppression device, through the interaction of the suction cavity, the magnet plates, the magnet columns, the excitation coils, heating plates and the like, most of the compressed air enters the suction cavity, so that the space of the compressed air is increased, and the pressure is reduced,so that the situation that the tinnitus occurs in the tunnel can be avoided.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a tunnel decompression device. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair; , production, military, and various engineering facilities for scientific research services. [0003] But now when the train enters the tunnel, due to the instantaneous compression of the air, temporary tinnitus often occurs, which makes many passengers feel uncomfortable. Contents of the invention [0004] The purpose of the present invention is to solve the following shortcomings in the prior art. Now when the train enters the tunnel, because the air is compressed instantaneously, the phenomenon of temporary tinnitus often occurs, which makes many passenge...
