DEVICE FOR RAISING THE MANHOLE FRAME AND METHOD FOR REPAIRING THE MANHOLE USING THE SAME
The present invention relates to a device to raise a manhole frame of a manhole buried between a road paving surface and a concrete structure made of a manhole frame and a manhole cover. The device to raise a manhole frame of a manhole comprises: a main body frame with fixing brackets coupled and fixated with and to an upper border of the manhole frame at a predetermined interval; a handle unit assembled on an external side of the main body frame at a predetermined interval wherein the handle unit includes a plurality of fixing bodies penetrating a long hole to guide a predetermined length on an external side of the main body frame, and includes a guiding protrusion coupled with the long hole to guide the external side of the main body frame to make a mobile body reciprocate in the inner holes of the fixing bodies; and a raising unit with a screw member of a predetermined length reciprocating during rotation by being coupled with a screw hole which penetrates the mobile body. The manhole frame is raised by matching the manhole frame with the road paving surface by rotating the screw member which the road paving surface contacts while the guiding protrusion rotates to vertically arrange the mobile body to the fixing body around a rotational center.
