An apparatus for inspecting a water pipeline is provided to clean the water pipeline easily by shutting off the inflow and outflow of the water completely when upper and lower partitions meet the center of the valve bodies. An apparatus for inspecting a water pipeline comprises a man hole(10), and multiple valves. The manhole includes a manhole body(11), a supporting part(12), a water proof cover(13), and a protective cover(14). The manhole body includes two connecting holes and draining holes. The supporting part supports the manhole body at the lower part of the manhole body. The water proof cover shuts off the upper hole of the manhole body. The protective cover, installed at the outside of the water proof cover, protects the water proof cover. The valves include valve bodies, opening and closing partitions, and lifting rotary shafts. The opening and closing partitions are divided into upper and lower partitions. |
