Abstract:
PROBLEM TO BE SOLVED: To provide the connecting structure, which can sufficiently follow a displacement of the ground due to earthquake and differential settlement without generating a fear of a breakdown.
SOLUTION: (A) A precast concrete end plate 2, which has the same number of through hole with the number of cable through hole of a precast concrete porous pipe and in which a connecting sleeve is embedded so as to cover the inner wall of the through hole, is fitted to a connecting end surface of the precast concrete porous pipe. (B) The same number of through hole with the number of the cable through hole of the precast concrete porous pipe is drilled in a hand hole member connecting side wall and a circular sleeve is projected from each through hole at the connecting end side. (C) One end of a connecting pipe 12 is inserted into the through hole of the precast concrete end plate 2 and the other end thereof is inserted into the circular sleeve 9 so as to connect both them.
