IMPERVIOUS WALL STRUCTURE AND IMPERVIOUS WALL CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To quickly construct an impervious wall structure by a small number of persons by injecting liquid into the inside of a cylindrical member having flexibility and continuously providing it along the side edge part of sea and a river in a cylindrically expanded state. SOLUTION: A cylindrical woven fiber 5 having a watertight layer and flexibility capable of being cylindrically expanded and collapsed in the form of a strip is provided. The cylindrical woven fabric 5 in a state where it is collapsed in the form of a strip is continuously provided along the face of the crest of the embankment of sea and a river. Next, both ends of the cylindrical woven fabric 5 are closed, and liquid such as water 6 is injected in the inside to be made a state where it is cylindrically expanded. Thereby impervious wall structure producing no water leakage and collapse can be quickly and continuously constructed by a small number of persons. An expansive admixture is sealed in the inside of the cylindrical woven fabric 5, expanded by injecting water 7, and the cylindrical woven fabric 5 may be constituted to be expanded.
