METHOD FOR BUILDING BYPASS MANHOLE

摘要

PURPOSE: A method for building a bypass manhole is provided to reduce the period of construction work, to prevent a bypass from lowering, to easily repair, to reduce cost, and to remove the factor threatening walkers by installing the bypass in a manhole. CONSTITUTION: A water gutter(5) having a bypass connecting unit(6) is installed in an inlet(4) of a manhole(1). The upper end of the bypass is fixed in the bypass connecting unit. A bypass(3) is settled on the wall of the inlet using a set anchor(7) and a band(8). As the bypass is installed inside the manhole, making an underground hole is not needed. Therefore, period of construction work and cost are reduced.
