Pier having Precast Concrete Pipe

The subject innovation are precast concrete as a hollow tube die bridge piers and on the application method using, by providing an additional technique that can be easily constructed by bridge piers of charges while not using a mold and Shore, dice and Shore installation and to avoid cumbersome and risky task of the demolition and reduce costs accordingly and for the purpose of devising so that the air can be reduced. In the present design is made of precast concrete of the tubular member with a hollow formed at the center are laminated assembly to mold features, and at the same time forms the exterior of the precast concrete pier hollow tube (10) and; A precast reinforcement mesh disposed in the hollow interior of a concrete hollow tube (10, 20) and; The reinforcement net 20 is cast-in-place to be embedded is composed of concrete (30) filling the hollow interior of the precast concrete hollow tube (10); Wherein the precast concrete hollow tube 10 is in the joint surface of the precast concrete hollow tube 10 when the laminate using the precast concrete hollow tube which comprises a concave-convex coupling by the recess portion and the projection of concrete pier It is provided. Precast concrete piers, hollow tube, die, Shores
