摘要： PROBLEM TO BE SOLVED: To provide a bridge pier construction method and a bridge pier formed by the bridge pier construction method wherein foundation piles and a footing formed of a prestressed concrete slab can be easily connected in a short time.
SOLUTION: The predetermined number of foundation piles 7 with threaded holes 17 formed in pile heads 16 are installed in the ground, and the footing 2 formed of the prestressed concrete slab is placed on the predetermined number of foundation piles 7. Screw shanks 21 of cap bolts 20 are inserted through the footing 2 from the top of the footing, and screwed to the pile heads 17 of the foundation piles 7 and tightened to fix the footing 2 to the foundation piles 7. The footing 2 can thereby be fixed to the foundation piles 7 in a short time with simple work not requiring technical knowledge and expertise of pressure welding, welding, reinforcement, and the like.

摘要： PROBLEM TO BE SOLVED: To provide a bridge pier foundation construction method and a floor slab for a bridge pier capable of markedly shortening construction term up to the completion of a foundation as compared with a conventional construction method. SOLUTION: The floor system 1 made of PC concrete and provided with a predetermined outward shape dimension and pile holes 3 in which piles 2 are inserted is formed in advance, holes 6 for installing the floor system 1 are digged in floor system installation sections, the floor slab 1 is sunk and provided in the digged holes 6, and then the piles 2 are driven down to a predetermined depth in the ground through the pile holes 3 to connect the floor system 1 with the piles 2. Consequently, construction term for digging holes is shortened, reinforcing bar construction work and form construction work for the floor system 1 in the digged holes and floor system concrete construction work become unnecessary, and construction term can be shortened.
