SOUNDPROOF WALL WITH DOOR FOR MAINTENANCE INSTALLED THEREON

WIPO Patent Application WO/2022/265159

A1

The present invention relates to a soundproof wall in which a door is installed. It is difficult for operators to access and maintain conventional soundproof walls to inspect and repair fastening members coupled to the outside thereof. In particular, for a soundproof wall installed on an elevated bridge, a problem exists wherein inspecting a fastening member by using a maintenance vehicle requires manpower and a substantial amount of time. Accordingly, proposed is a soundproof wall in which a door for maintenance is installed such that an operator can easily access the fastening member coupled to the outside of the soundproof wall by installing the door at the bottom of the soundproof wall. In addition, the present invention has the advantage of reducing time and cost by using the existing concrete foundation, posts, and soundproofing plates, and arranges a stopper or a variable part to keep the door in an open state, thereby preventing operator accidents.
