The invention discloses a bridge integrally-assembled
pier and a construction method. The
structural system of the bridge integrally-assembled
pier is composed of integrally-assembled PHC
pipe piles, assembled bearing platforms, an assembled tie beam, segment prefabricated
pier bodies, an assembled cover beam and other components. The assembled bearing platforms, the assembled tie beam, the segment prefabricated pier bodies and the assembled cover beam are connected through steel pipes and a prestressing
system. In the installation process, a prestressing
tendon penetrates through all the components at first, positioning is completed through steel
pipe sleeves under the
self weight condition, the prestressing steel
tendon is tensioned integrally, and a
system is formed. According to the bridge integrally-assembled pier and the construction method, the components all adopt an industrialized production process and an
assembly installation process, the construction period is shortened, and environment protecting is facilitated; a part of the components is made of high-strength concrete, so that materials are saved, and the construction cost is reduced; the detachable, replaceable and recycling effects are achieved, and energy saving and emission reducing are facilitated; and the seismic performance of the
system is excellent.
