摘要： PROBLEM TO BE SOLVED: To provide an air leakage prevention device which can impose a great tensioning force on an anchor material, which can flexibly absorb a construction error of the anchor material, and which sufficiently secures airtightness even under high air pressure.SOLUTION: An anchor material 1 is made of a plurality of grease-impregnated unbonded prestressing steel strands 11. An air leakage prevention device 2 includes a casing pipe 3 in which a filler 21 is housed and through which each of the prestressing steel strands 11 is to be individually inserted, and upper and lower heads 4 and 5 which are provided in upper and lower openings of the casing pipe 3, respectively, and which comprise insertion portions 40 and 50 for individually inserting the prestressing steel strands 11, respectively, and packing compressing portions 40p and 50p for compressing gland packing 12 attached to each of the prestressing steel strands 11.
