PROBLEM TO BE SOLVED: To provide an eco-friendly technology for shortening a construction period, and reducing cost in construction work, by exhibiting the function as an insertion reinforcement and a safety device, simultaneously when adjusting a height and an attitude when regenerating similarly to new construction, by installing a side ditch regeneration structure in an upper cutting area of an existing side ditch.SOLUTION: A height-attitude adjusting mechanism 8 constituted in a frame body 6 installed on a cutting surface 4 of the existing side ditch, comprises an adjusting hole 8h penetrating toward the cutting surface 4 and constituting a first screw part S1 and an adjusting bolt 8t constituting a second screw part S2 threadedly engaging with the first screw part. In a state of installing the frame body 6 on the cutting surface 4, the adjusting bolt 8t is operated from a surface 6a side of the frame body 6, and a tip 8b thereof is constituted by protruding-retreating from a reverse surface 6b of the frame body 6. |
