摘要： PROBLEM TO BE SOLVED: To sufficiently obtain effects of strengthening a supporting force of a pile distal end portion foundation or reducing a pile subsiding amount while suppressing cost.SOLUTION: When cement milk to be injected is switched to non-permeable cement milk after filling an injection hose 21, a bag body 20 and a discharge hose 22 with permeable cement milk, in the case where the bag body 20 is broken and the cement milk is leaked to the outside, meshes of an ambient ground Gb is clogged with a particle size adjustment member contained in the non-permeable cement milk. Thus, the permeation of the cement milk into the ambient ground Gb is suppressed. As a result, while suppressing consumption of the cement milk, effects of strengthening a supporting force of the ambient ground Gb in the distal end portion of a foundation pipe or reducing a subsiding amount of the foundation pile can be obtained at a low cost.
