An annular reinforcing structure for the reinforcement of a supporting structure of a construction is provided. The annular reinforcing structure includes an outer frame body, an inner frame body and an elastic body. The inner frame body is connected to the outer frame body and positioned therein. The inner frame body and the outer frame body together define an annular space. The elastic body is accommodated in the annual space between the inner frame body and the outer frame body.

A precast segment suitable for block-stacking concept is disclosed. The precast segment includes a first surface, an opposite second surface, plural through holes, and plural male-female connecting sets. The through holes extend from the first surface and toward the second surface to communicate between the first surface and the second surface. Each male-female connecting set includes a shear key and a joint hole, wherein the shear key protrudes from one of the first surface and the second surface to serve as a male connecting unit, and the joint hole is formed in the other of the first surface and the second surface to serve as a female connecting unit. Accordingly, the precast segments can be block-stacked by mortise-and-tenon joints to construct a bridge pier system. Compared to the conventional construction methodology, the present invention can enhance the efficiency of segment fabrication and avoid high prestress force.
