A manhole apparatus having a dirt isolation function is provided to improve the economical efficiency by preventing a rainwater pipe from being choked by dirt and to reduce the discharge burden of a rainwater pipe. A manhole apparatus having a dirt isolation function whose upper part is opened for inflow of rainwater and dirt is buried under the ground. The manhole apparatus having the dirt isolation function is composed of a manhole wall(100) in which an end projection(110) is formed in the upper part and a rainwater pipe(120) is connected to the lower part, a frame(200) in which a hanging member(210) is projected to the outside in the upper part and a fixing member is projected to the inside in the lower part, an inclined diaphragm(300) which is inclinedly combined to both inside sides of the frame and moves rainwater and dirt flowed in from the upper part of the manhole wall, a collecting box(400) which has water conveyance holes and collects dirt from the diaphragm, a manhole cover(500) in which the external periphery is fixed to the end projection of the manhole wall, which is positioned at the upward of the hanging member, an intercepting diaphragm(900) intercepting the opened part between the inclined diaphragms, a rotary diaphragm(600) which is hinge-combined at the upper end of the collecting box, a restriction member, and a knob. |
