<p>The present invention relates to a field assembly type live line precast manhole for repair and a construction method thereof and, more specifically, to a field assembly type live line precast manhole for repair and a construction method thereof capable of installing the precast manhole in consideration of site conditions, such as the position, direction, and height of obstructions, while preventing the shifting construction, damage, and position deviation of the obstructions, and assembling the precast manhole in the site to be easily installed. The field assembly type live line precast manhole for repair comprises a variable body part (10) which is a foundation of a steel frame and a precast upper plate part (20) coupled to the top of the variable body part (10). A method to construct a field assembly type live line precast manhole for repair comprises: a step of excavating the site (S10); a step of checking the continuous footing and excavation of an installation place (S20); a step of disassembling an existing structure and arranging facilities (S30); a step of constructing a foundation and a new structure (S40); and a step of constructing walls and filling back soils around the walls (S50); a step of installing a cut-off plate and coupling a precast (PC) upper plate (S60); a step of constructing and paving the manhole structure (S70); and a step of removing forms and finishing the construction (S80).</p> |
