<p>The present invention relates to a light weight and soundproof tunnel and, specifically, to a light weight and soundproof tunnel installed in a road or a railroad (including a high-level road and a high-level railroad). According to the present invention, as a frame of a soundproof tunnel is light-weighted and rigidity is the same with an H-shaped frame, the tunnel can be built even in the ground or the existing high-level road and high-level railroad without additional costs. Moreover, the soundproof tunnel comprises: frames (10) to fix opening parts at regular intervals in a construction position; and a soundproof panel (20) inserted and supported between the frames (10). The frame (10) is formed in the form of a polygon as inner and outer lateral plates (11a, 11b) are arranged at regular intervals, a connection plate (12) is integrally extruded with an aluminum alloy between the inner and outer lateral plates (11a, 11b), and a void (C) having a closed cross section, and supporting protrusions (13a, 13b) are formed in both lateral surfaces of the inner and outer lateral plates (11a, 11b). Moreover, the soundproof panel (20) is inserted and supported between supporting protrusions (13a, 13b) of the both frames (10).</p> |
