FILLING INSPECTION DEVICE AND FILLER MATERIAL INJECTION METHOD
To ensure that the gap between an existing pipe and an inner tubular body to be installed during construction is properly filled with filler material.SOLUTION: There is provided a filling inspection device 100 that inspects the filling status of filling material between an existing pipe and a tubular body provided inside the existing pipe. The filling inspection device 100 includes a float 10 that moves up and down according to the specific gravity of fluid in the inspection hole provided at the bottom of the tubular body, and a detector 20 for detecting the amount of movement of the float. The float has a tapered shape at least partially narrowed toward the lower end side of the float on the portion that contacts the fluid.SELECTED DRAWING: Figure 1
【課題】施工中に既設管とその内側に設けられる管状体との間の間隙に充填材が適切に充填されたことを確認する。【解決手段】既設管と該既設管の内側に設けられる管状体との間に充填される充填材の充填状況を検査する充填検査装置１００を提供する。充填検査装置１００は、管状体の底部に設けられる検査孔における流動物の比重に応じて上下移動する浮子１０と、浮子の移動量を検出する検出器２０と、を備え、浮子は、流動物と接触する部分において、少なくとも一部に浮子の下端側に向かって狭められるテーパー形状を有する。【選択図】図１
