Manhole for power distribution line having earthquake proof function

The present invention relates to a manhole for a power distribution line having an earthquake proof function, which comprises: a lower end reinforcing block having a corner lower end reinforcing block and a wall lower end reinforcing block; an upper end reinforcing block having a corner upper end reinforcing block and a wall upper end reinforcing block; a lower end reinforcing block drive means and an upper end reinforcing block means, a power device; and an external reinforcing means. Therefore, the manhole is strong against strong vibration caused by an earthquake, and a manhole of a conventional power distribution line can be quickly, conveniently, and safely reinforced. 본 발명은 내진기능을 갖춘 지중배전선로 맨홀장치에 관한 것으로, 구석하단보강블록과 벽체하단보강블록을 포함하는 하단보강블록과, 구석상단보강블록과 벽체상단보강블록을 포함하는 상단보강블록, 하단보강블록구동수단과 상단보강블록구동수단, 전원장치 및 외부보강수단을 포함하여, 지진에 의한 강한 진동에 강하며, 기존 지중배선선로의 맨홀을 신속하고 간편하며 안전하게 보강할 수 있도록 한 것이다.
