Conventionally installed inspection passages are generally constructed such that a main frame is installed on the top of a bridge pier after the completion of the alternating and pier structure, or the bridge is fixed to the pier wall surface using an anchor. When the main frame is installed over the member, a member for hanging over the bridge is required, so that more members than necessary are used, which is uneconomical. Even in the case of an anchor system, a member for fixing to the pier wall is required. In particular, piercing an anchor hole in an already completed pier can damage the pier structure.

As a background of the present invention, there is a patent registration 10-1293853 'bridge check passage' (patent document 1). This patent proposes a bridge check passage that allows the footplate to be installed simply and horizontally even if the wall of the pier is inclined. This patent proposes a bridge check passage which enables the horizontal placement of the footrest mounted on the footrest even if the wall surface of the bridge is not vertical, thus securing a safe and balanced walking path for the inspector. However, There is a problem in that the anchor hole must be drilled in the pier to fix the pier structure.
