SEALING STRUCTURE FOR PREVENTING OUTFLOW OF GROUT BETWEEN PILE AND SLEEVE PIPE

PROBLEM TO BE SOLVED: To provide a sealing structure for preventing the outflow of grout between a pile and a sleeve pipe, which can enhance productivity in a factory, which can be worked outside the sleeve pipe, and which is excellent in construction work characteristics. SOLUTION: This sealing structure comprises an outwardly projecting annular flange part 12 at the end of the sleeve pipe 2. The seal member 11 of an elastic body having an annular seal part 11a projecting to the inside of the sleeve pipe 2 is brought into contact with the flange part 12. A retaining member 13 having a retaining ring part 13a is brought into contact with the seal member 11. The seal member is held and fixed by a fixing member 15 from the outside. Since the seal structure 10 can be mounted on the outside of the sleeve pipe 2, and boring and positioning for bolts are not required by holding and fixing the seal member, the manufacture and work can be easily performed.
