PURPOSE: A manhole maintaining method using a manhole housing supporting apparatus is provided to adjust the height of the level of a manhole by lifting the manhole without using a separate height adjustment device, and to increase construction safety by increasing the connectivity of a manhole housing and the manhole housing supporting apparatus. CONSTITUTION: A manhole maintaining method using a manhole housing supporting apparatus comprises the following steps of: the step of cutting the periphery of an existing manhole with a cutter, removing the road surface layer between the outer circumferential surface of a manhole housing and a cutting line by excavating and breaking, and then lifting the manhole housing after moving a manhole cover; the step of installing a tube form(40) in the bore side of the hole of a slab(50) in the manhole; the step of combining the manhole housing supporting apparatus with the manhole housing; the step of installing the manhole housing supporting apparatus combined with the manhole housing in the periphery of the manhole; the step of controlling the tube form by installing a controller(60) on the center of the tube form; the step of filling the filler into the space of a cut section and the outer circumferential surface of the manhole housing; and the step of removing the manhole housing supporting apparatus and installing a manhole cover.
