The manhole repairing method using a manhol housing supporthing apparatus and a cast for the repair work of a manhole

摘要

The present invention relates to a method of repairing a manhole using a manhole housing supporting device and a mold for repairing a manhole, and more particularly, to a method of repairing a manhole using a manhole housing supporting device and a mold, Removing the road surface layer between the outer diameter surface of the manhole housing and the cut line after cutting the periphery by a cutter, excavating and breaking the road surface layer, moving the manhole cover and pulling up the manhole housing, and (b) (C) a leg member having a long rod shape, a fixing portion provided on one side in the longitudinal direction of the leg member, and a first through hole in the middle, and two or more leg members And a fixed body having a fixing hole passing through one side of the upper face, A fixing member fixed at one end to the upper surface of the leg member through the fixing hole and fixed to one side of the outer circumferential surface of the leg member, and a release lever provided inside the pair of first and second knobs, A manhole housing is coupled to a manhole housing supporting device composed of a conventional vise plier in which a first handle and a second handle are rotatably connected so that a bite is provided under one side of the handle, and the upper surface of the first handle of the vise flyer The manhole housing is coupled to the manhole housing supporting device by moving the fixing body according to the size of the manhole housing and then fixing the upper end of the manhole housing with a vise flyer, (C) installing a manhole housing support device having a manhole housing coupled thereto around a manhole to position (F) filling the space between the cut surface and the outer diameter surface of the manhole housing with a filler; and (g) inserting the filler into the space between the cut surface and the outer diameter surface of the manhole housing, Removing the manhole housing from the manhole housing supporting device, removing the manhole housing supporting device and the form, and covering the manhole cover on the upper surface of the manhole housing. Since the present invention uses an optimized formwork and a manhole housing supporting device in the repair work of the manhole, the construction can be simplified compared to the existing manhole repairing method, and the air can be shortened.
