Abstract:
PROBLEM TO BE SOLVED: To easily set an impervious wall in the case where a gutter pipe is provided by releasing a folding force after the impervious wall for the gutter pipe folded previously for the attaching space of the impervious wall excavated from the inside of the pipe is carried in, in the case where the impervious wall is attached after the gutter pipe is provided on a bank.
SOLUTION: A gutter pipe for an impervious wall 6 is composed of an impervious wall member 8 formed of disk-like and foldable substance, for instance, a rubber sheet, a rubber coated sailcloth, a waterproof-treated sailcloth, a lightweight synthetic resin-made thin cloth having waterproofness or the like fixed on the outer face of a pipe-like core 7 capable of being fixed on the inner face of the gutter pipe and an elastic core member fixed along the circumference on the outer edge of the impervious wall member 8. The impervious wall member 8 is constituted so as to be twisted to be formed into three rings, next, to be axially folded into three pieces, and to be restored and deformed to an original disk-like one by elasticity of the elastic core member 9 by releasing the folding forced. Thereby execution of the impervious wall can be improved.
