新案登録請求の範囲第１項記載のトンネル覆工用
セグメントの止水構造。[Claims for Utility Model Registration] (1) Using segments consisting of a main girder part, a joint part, and an outer skin part, when joining the segments, the longitudinal direction between the main girder parts and the joint part of adjacent segments is It has a structure of wide long grooves provided in the
Since the wide long groove has a substantially trapezoidal cross section and the upper side of the trapezoid is curved upward in an arc, the strength of compression can be adjusted between the upper side and oblique side of the trapezoid of the opposing wide long groove between adjacent segments. A water-stop structure for a tunnel lining segment, characterized in that the segment is attached to the tunnel lining. (2) A water-stop structure for a tunnel lining segment according to claim 1, wherein the sealing material is water-expandable.
