A PREFABRICATED MANHOLE STRUCTURE FOR SUBTERRANEAN CABLE

摘要

A prefabricated manhole structure for subterranean cable is provided to reduce construction time and installation cost since repairing and reconstructing of the manhole is carried out without interruption of electric power. In a prefabricated manhole structure for subterranean cable, a cable pathway(2), through which a ground cable is passed is installed at upper and lower part sleeve and manhole box body(3) is composed of side walls. The manhole box structure has a manhole cover(4), which is opened and closed and installed on the top sleeve of this manhole box body. A semi-circular unit is formed by the lower sidewall of the upper sidewall(5), the upper sidewall of lower-sidewall(7) and upper /lower sidewall of middle walls(6a,6b).
