PURPOSE:To shorten the period of construction by a method in which concrete blocks with sheath tubes are set on the seabed, piles are inserted into the sheath tubes, and an adhesive is supplied into the piles to bond the piles with the sheath tubes. CONSTITUTION:The surface of the rock bed R of the seabed is treated and precast concrete blocks 1 into which sheath tubes 10 are set at a given angle are set on the rock bed R. Piles 20 are inserted into the tubes 10, and an adhesive M, e.g., cement mortar, etc., is supplied into the piles 20 to fill up the aperture S between the piles 20 and the tubes 10. |
