<p>The present invention relates to a method for pouring a bonding filler after forming a hole portion at a perforation hole which is bored in a depth direction of the ground in order work on an expansion portion at which a pile or a tensile member for construction works is erected. A balloon containing the curable bonding filler is arranged at a leading bottom portion of the pile or tensile member, and the pile or tensile member is lowered down to the bottom of the hole portion. Then, the pile or tensile member is pressed such that the balloon disposed at the bottom portion is compressed in the vertical direction, and expands in the radial direction up to an outline of the hole portion. The bonding filler in the expanded balloon is filled in the hole portion while the dimensions of the hole portion are maintained.</p> |
