The present invention relates to a screening apparatus for foreign substances of a manhole. The objective of the present invention is to provide a screening apparatus for foreign substances of a manhole, which can be simply installed only by a process of being mounted on the bottom without separately processing the inner bottom of a manhole and which can filter foreign substances without being turned over in spite of the rapid flow of sewage. To achieve the objective of the present invention, the apparatus comprises: a screen body having a convex inverter groove insertion part formed on the lower part thereof to be inserted into a concave inverter groove formed on the bottom of a manhole while being installed on the outlet side of the inner bottom of the manhole to filter the foreign substances of sewage discharged to an outlet from an inlet; and a plurality of support plates installed on the lower surface of the screen body and closely adhered to the bottom of the manhole for preventing the turnover of the screen body. |
