摘要： PROBLEM TO BE SOLVED: To provide a tunnel exfoliation protective structure suitable for repairing an existing tunnel, capable of being easily and rapidly constructed depending on a clearance limit, reinforcing a lining wall inner surface, preventing exfoliation, and preventing water leakage, and a tunnel repair method.SOLUTION: In a tunnel exfoliation protective structure, a reinforcement sheet 7 made of a fiber-reinforced plastic is installed on an inner surface of a tunnel lining wall 4. A plurality of support frames 12 are engageably arranged on an inner surface of the reinforcement sheet 7 along the circumferential direction of the inner surface of the tunnel lining wall 4, the support frames 12 are provided so as to be curvedly formed in a smaller diameter than that of an upper peripheral surface of the inner surface of the tunnel lining wall 4 and are installed so that curvature elasticity of the curvedly formed support frames 12 can energize the side of the reinforcement sheet 7 and the lining wall 4, and the reinforcement sheet 7 is installed so as to come in press-contact with the side of the lining wall 4.

摘要： PROBLEM TO BE SOLVED: To surely prevent a filler from leaking to the inside of a drilling hole in drilling execution of filling the filler between a hole wall and a protective pipe.SOLUTION: A seal device includes a cylindrical seal body 24 attached to a lower end of a hole wall protective pipe 20 and extended upwards from the lower end to a prescribed height range along a drilling hole wall, and a sheet 25 arranged on an inner side of the seal body 24 and attached to the lower end of the hole wall protective pipe 20. For the seal body 24, a bottom part between the lower end of the hole wall protective pipe 20 and the hole wall has rigidity against a load of the filler, at least a cylindrical part along the hole wall is divided into multiple parts in a circumferential direction, and respective division parts 27 have elasticity so that they can be closely attached to the hole wall independently.
摘要翻译：要解决的问题：为了确保防止填料在孔壁和保护管之间的钻孔执行中泄漏到钻孔的内部。解决方案：密封装置包括：圆柱形密封体24，其附接到孔壁保护管20的下端，并沿着钻孔壁从下端向上延伸到规定的高度范围;以及片25，布置在密封体24的内侧并且附接到孔壁保护管20的下端。对于密封体24，孔壁保护管20的下端和孔壁之间的底部具有抵抗填料的填充物，至少沿着孔壁的圆筒部分在圆周方向上分成多个部分，并且各个分隔部分27具有弹性，使得它们可以独立地紧密地附接到孔壁。版权所有（C）2013，JPO＆INPIT
