PROBLEM TO BE SOLVED: To provide a concrete structure joint method for adequately coping with uneven settlement and the displacement of soil in earthquake without using a complicated water cutoff member such as a rubber.SOLUTION: A plurality of box culverts 1 as concrete structures shaped cylindrical in cross section are placed at predetermined distances from one another, and backup members 22 of non-polar materials are installed in areas distant from the inner faces of the box culverts 1. Into spaces between the surface of each backup member 22 and the inner face of each box culvert 1, adhesive agent 21 is poured which has an elongation capability of 100-250% and a density of 0.8-1.0 g/cm, to form joint parts. |
