摘要

An objective of the present invention is to provide a live wire precast manhole and an installation method thereof which facilitate installation in a live wire state without relocating or damaging an obstruction complexly buried underground. According to the present invention, the live wire precast manhole comprises: an upper plate unit having at least one hole in which a manhole cover is mounted; a plurality of pillars which are integrated into the upper plate unit by precast concrete, and support the upper plate unit; a through hole formed between two neighboring pillars, through which an obstruction passes; and an exposed rebar exposed to the upper plate unit on a side of the through hole and one surface of the pillars to be buried in concrete when forming a side wall.
