摘要： PROBLEM TO BE SOLVED: To provide an underground penetration method for a steel member in which the steel member can be made to easily penetrate into the ground through simple facilities.SOLUTION: A steel member 11 has an axis in a vertical direction, and has a part in a closed shape in a horizontal cross section. Namely, a steel pipe 11b is joined to the steel plate member 11a in one body. While air bubbles formed by foaming a surface active agent are pressed in the steel pipe from above to be ejected into the soil nearby a lower end of the steel member, the steel member is made to penetrate into the ground. As the air bubbles are charged among soil particles, gap pressure rises and the surface active agent gets in among the soil particles, which become easy to slide on one another.

摘要： PROBLEM TO BE SOLVED: To provide an expansion steel pipe for restoring a settlement foundation which can increase the amount of the recovery of the settlement foundation.
SOLUTION: The expansion steel pipe is composed of a deformed pipe body with a watertight structure in which cylindrical sleeves with strength high enough to prevent deformation from being caused by the addition of high water pressure are mounted at both ends, respectively. Any of longitudinal cross sections of the pipe body has the same peripheral length. A portion of the pipe body adjacent to the sleeve is composed of a concave cross section, and a portion except the portion adjacent to the sleeve is composed of a flattened cross section. The pipe body has a structure in which either of the sleeves has an injection hole. An increase in the height of the cross section of the pipe when the flattened cross-section portion is expanded and deformed into a circular cross section by the injection of the high pressure water from the injection hole is utilized for the restoration of the settled foundation.
