The invention provides a joining method of concrete structures. The purpose of the present invention is to give shock resistance, continuity and water tightness inexpensively and easily by using concrete structure products with cylinder-shaped or U-shaped cross-sections. A plurality of box culverts (1) with cylinder-shaped cross-section as concrete structure products are paved with a predetermined interval. A non-polar substance supporting sealing material (22) is arranged at the portion spaced from inner surface of the box culvert (1). A junction portion (2) is formed by injecting an adhesive agent (21) with a stretching capacity of 100-250% and a density of 0.8-1.0 g/cm3 into the space between surface of the supporting sealing material (22) and the inner surface of the box culvert (1). |
