PURPOSE: A soundproof tunnel structure is provided to improve workability by downwardly dismantling a soundproof plate with a separable support angle. CONSTITUTION: A soundproof tunnel structure comprises a pillar, a roof frame(110), a roof frame connecting member, a fixing member(120), a supporting angle(122), a soundproof plate(130), and a gasket(140). The fixing member is arranged at an upper surface of the roof frame. The supporting angle is installed at both sides of the fixing member, and both ends of the soundproof plate are hung. The supporting angle is separated from the fixing member, and the soundproof plate is downwardly separated when dismantling the soundproof plate.
