REPAIR METHOD OF PILLAR ROOT IN FALL PREVENTION HANDRAIL

摘要

PROBLEM TO BE SOLVED: To provide a repair method capable of discharging stagnated water in a fixed support to the outside without separately using a water absorption pump and performing repair without large heat generation by a filler for repairing a root portion of the fixed support with excellent workability.;SOLUTION: A lower opening 31 is formed with respect to a lower position in the vicinity of a frame 1 out of tubular fixed supports 10 in which the lower part is buried in the frame 1. A filling material C obtained by mixing the epoxy resin, the hardening agent and the aggregate is supplied into the fixed support 10 through the lower opening 31 while flowing down from the height position in the vicinity of the lower opening 31. Stagnated water B is discharged from the lower opening 31 while replacing the filling material C with the stagnated water B present in the fixed support 10. The filling material C is filled up to the lower end position of the lower opening 31. After a predetermined time, when the upper surface of a filling material D in the fixed support 10 is lower than the lower end position of the lower opening 31, the filling material C is additionally filled in the fixed support 10.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2018,JPO&INPIT
