摘要

PURPOSE: An underpass using precast concrete piles and a bottom slab and a construction method thereof are provided to prevent damage to a bottom slab by installing shear keys in the whole of a pile body. CONSTITUTION: An underpass using precast concrete piles and a bottom slab comprises wall bodies, a cast-in-place top slab, and a bottom slab. The wall bodies are formed by installing multiple precast concrete piles in a line. The top slab connects the top ends of the wall bodies. The bottom slab is formed by connecting multiple segments(31) to each other along the traveling direction of a vehicle and connects the bottom ends of the wall bodies.
