REPAIR METHOD OF PILLAR ROOT IN FALL PREVENTION HANDRAIL
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
【課題】別途吸水ポンプを用いることなく固定支柱内の滞留水を外部に排出でき、固定支柱の根元部分を補修する充填材によって大きな発熱を伴うことなく補修を行うことができ、しかも作業性の優れた補修工法を提供する。【解決手段】下部が躯体１内に埋設された筒状の固定支柱１０のうち、躯体１近傍の低い位置に対して下開孔３１が形成される。エポキシ樹脂と硬化剤と骨材とを混合した充填材Ｃが、下開孔３１を通してかつ該下開孔３１付近の高さ位置から流下されつつ固定支柱１０内に供給される。充填材Ｃと固定支柱１０内に存在する滞留水Ｂとが置換されつつ、滞留水Ｂが下開孔３１から排出される。充填材Ｃは、下開孔３１の下端位置まで充填される。所定時間後、固定支柱１０内の充填材Ｄの上面が下開孔３１の下端位置よりも沈下しているとき、固定支柱１０内に充填材Ｃを追加的に充填する。【選択図】 図４
