PURPOSE:To contrive the elimination or reduction of labor in repair work by compressing a bellows-shaped filler vessel able to extend and contract by a compressing member of spring or the like and injecting a sealant in the vessel into a crack generated in a concrete structure or the like. CONSTITUTION:A filler pipe 2, provided with a seating plate 21, is fixed by an adhesive agent 3 to one part of a crack II generated in a concrete surface, and a surface of the rest part of the crack II is sealed. Next the filler pipe 2 connects an empty bellows-shaped filler vessel 5 able to extend and contract, thereafter the vessel 5 is compressed and held between retaining members 4a, 4b of spring plate or the like and a compressing member comprising a spring 16, bolts 15 and nuts 16. And the vessel 5 is charged in its inside with a sealant 8 through a check valve 11, injecting the charged sealant into the crack II at a low speed and low pressure. Thus eliminating almost the necessity for performing filling work by labor, further unevenness can be prevented of a filling condition. |
