A manhole easily connected with a connecting pipe is provided to fix the connecting pipe, and to improving water tightness of the connecting pipe coupled area by compressing a packing with a fixing plate. A manhole easily connected with a connecting pipe comprises a manhole body(10), an installation part(12), a packing(30), a plurality of insert nuts(40), a fixing plate(20), and a coupling bolt(41). The manhole body is formed with at least one connecting hole. The packing is inserted in the installation part, deformed like a shape of the installation part, and installed for water tightness between the connecting pipe and the connecting hole. The fixing plate compresses the packing for fixation with the connecting pipe. The coupling bolt is coupled with the insert nut to fix the fixing plate. The fixing plate includes a ring shaped body(21) having a plurality of through holes(23), and a compression projection. The packing includes an insertion part(31) having insertion grooves(32), and a wing part(33). |
