It was reported in the previous paper, Part 1, that cast-in-place reinforced concrete piles with enlarged points should be reinforced by steel pipes at the heads when horizontal force caused by earthquakes are great. The pipes have ribs on their inner surfaces in order to secure big bond strength between pipes and concrete even under bad construction conditions. In the present paper, three construction methods are introduced on which construction tests are carried out to make the methods used in practice. After the tests, the strength of the reinforcement are examined by loading tests. The reinforcement consists of the steel pipe concrete and the joint between steel pipe concrete and reinforced concrete and is made in fields by the above-mentioned construction methods. The bearting capacity of the reinforcement is proved to be excellent.
