PROBLEM TO BE SOLVED: To provide a sludge scraping apparatus in which work efficiency upon installing a supporting mechanism is improved, and relative positional relationship between flight plates and pressing members can be accurately adjusted.SOLUTION: The sludge scraping apparatus is provided in which a plurality of flight plates 5 attached to a pair of endless chains 4 trained over between support shafts travels along guide rails 7 to scrape sludge accumulated on basin bottom of a sedimentation basin. Pressing members 8 preventing the flight plates 5 from floating are supported with a supporting mechanism on the side opposing to guide rail 7 in a such a manner that the flight plates 5 are sandwiched therebetween. The supporting mechanism comprises: a supporting member 9A arranged in such a manner that the supporting member 9A is fixed on wall surface of the sedimentation basin and projects to the side of the pressing member 8; a first attaching member 9B attached to a the supporting member 9A via a first fastening mechanism 91 capable of adjusting attaching position on the side of the pressing member; and a second attaching member 9C fixing the pressing member 8 onto the first attaching member 9B via a second fastening mechanism 92 capable of adjusting the separation distance h1 between the flight plate 5 and the pressing member 8. |
