Abstract: 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.

Abstract translation: 公开了一种适用于块堆叠概念的预制段。 预制段包括第一表面，相对的第二表面，多个通孔和多个阳 - 阴连接组。 通孔从第一表面延伸到第二表面，以在第一表面和第二表面之间连通。 每个公 - 母连接组包括剪切键和接合孔，其中剪切键从第一表面和第二表面之一突出以用作阳连接单元，并且接头孔形成在第一 表面和第二表面用作阴连接单元。 因此，预制区段可以通过榫眼和榫头关节来堆叠，以构建桥墩系统。 与传统施工方法相比，本发明可以提高节段制造的效率，避免高预应力。
