摘要： PROBLEM TO BE SOLVED: To provide a repair construction method for an exposed boundary part in a through pipe for easily and satisfactorily repairing a corroded section of the exposed boundary part in a pipe arranged and passing though a structure under the high humidity atmosphere and preventing corrosion of a repaired section. SOLUTION: This repair construction method comprises a first process for forming a ring platelike cut channel B3 being substantially concentrical with the pipe A on a peripheral region face B1 in a passing through part of the pipe A by a circle cutting machine C in which a platelike rotary blade 3 turns centered on the pipe A, a second process for forming an annular recessed part B4 by removing an annular region between the ring platelike cut channel B3 and the pipe A by a chipping tool D by predetermined depth, a third process for cleaning the corroded section A1 in the exposed boundary part in the pipe A after forming the annular recessed part B4, a fourth process for applying primer B5 over the cleaned corroded section A2 of the pipe A from the annular recessed part B4, and a fifth process for filling anticorrosive/quick hardening resin putty B6 over the cleaned corroded section A2 of the pipe A from the annular recessed part B4 on which the primer B5 is applied.

摘要： PROBLEM TO BE SOLVED: To provide a circle cutting machine for the perimeter of a pipe penetrating portion which circularly cuts an area on the perimeter of the pipe penetrating portion in a manner being almost concentric with the pipe and with a minimum diameter in order to repair the pipe of a different type arranged in a structure.
SOLUTION: The circle cutting machine is formed of a holding section 1 which holds the pipe A and is rotatably held, a dish-like rotary blade 3 pivotally mounted on a driving unit 2 in one body via a transmitting means, and a machine body 4 connecting the driving unit 2 to the holding section 1. The driving unit 2 is slidably connected to the machine body 4 in a restricted range restricted by a sliding restricting means 5 for restricting the sliding of the driving unit 2 to a predetermined direction and to a predetermined length. The rotary blade 3 has its dish-like recessed face adjacently formed to the holding section 1. Thus by the sliding of the rotary blade 3 caused by the sliding of the driving unit 2 and by the rotation of the rotary blade 3 on the pipe A caused by the pressing motion of the machine body 4, the area B on the perimeter of the pipe penetrating portion is circularly cut almost concentrically with the pipe A and with the minimum diameter.

摘要： PROBLEM TO BE SOLVED: To provide an insertion method of construction capable of preventing the outside surface of an insertion pipe from having a flaw.
SOLUTION: According to this insertion method, when the insertion pipe 12 is to be inserted, a corrugated pipe 14 is interposed between an existing line 10 and the insertion pipe 12. For example, the corrugated pipe 14 is inserted in the existing line 10, and then the insertion pipe 12 is inserted into the corrugated pipe 14. Otherwise, the corrugated pipe 14 and the insertion pipe 12 are simultaneously inserted into the existing line 10. The insertion pipe 12 will never touch the inside surface of the existing line 10. Because the touching area with the corrugated pipe 14 is small, the insertion resistance can be reduced. In case the existing line 10 has a bend 18, a diametrically contracted pipe is applied as the insertion pipe 12, followed by restitution after insertion. There is no risk that the insertion pipe has a flaw at its outside surface, and a drop in the performance can be precluded. It is possible to reduce the insertion resistance of the insertion pipe, a wire mounting tool, towing wire, etc.

摘要翻译：要解决的问题：提供一种能够防止插入管的外表面具有缺陷的结构的插入方法。解决方案：根据该插入方法，当要插入插入管12时，波纹管14插入在现有管线10和插入管12之间。例如，波纹管14插入到现有管线10，然后将插入管12插入到波纹管14中。否则，波纹管14和插入管12同时插入到现有管线10中。插入管12将不会接触现有的管线10的内表面由于与波纹管14的接触区域小，所以可以降低插入阻力。在现有管线10具有弯曲部18的情况下，将直径收缩的管作为插入管12施加，然后在插入后恢复。插入管在其外表面上不存在缺陷，并且可以排除性能下降的风险。可以降低插入管，电线安装工具，牵引线等的插入阻力。版权所有：（C）2004，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method capable of simply confirming that formed film thickness is not less than set film thickness without measuring the film thickness after construction of an in-tube lining.
SOLUTION: After a preparation process S1, a base treatment for forming a base surface having a specific color on an inside tube surface is applied to a tube (base treatment process S2), and a lining film becoming translucent at a thickness less than the set film thickness is formed on the base surface (lining film formation process S3). The color of the lining film is observed from the upper side of the formed lining film (observation process S4), and the construction state of the lining film is confirmed based on the observation color obtained by the observation (confirmation process S5).

摘要： PROBLEM TO BE SOLVED: To provide a method for inserting a corrugated pipe into existing piping and a convenient inserting fixture used for the inserting method capable of sending into the existing piping at one time in spite of a long distance without degrading its performance by folding the corrugated pipe.
SOLUTION: The inserting fixture with a guide pipe portion having an inner diameter approximately similar to an outer diameter of the corrugated pipe capable of being inserted by the corrugated pipe and an outer diameter capable of inserting into an existing pipe by means of pushing motions is confronted with one opening edge of the existing piping while the corrugated pipe is inserted into the guide pipe portion, and the guide pipe portion is pushed into the existing piping by holding the corrugated pipe at a pipe-axis direction of the guide pipe portion in a non-sliding state. After completing pushing motions, slide holding of the corrugated pipe is released, and pulling motions pulling the guide pipe portion from the existing pipe are repeated.
