Title:
REPAIR DEVICE FOR INNER FACE OF PIPE
Document Type and Number:
Japanese Patent JP3223314
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a repair device for the inner face of a pipe in which while contact-bonding flexible repair material having a water sealing agent consisting of photosetting resin solution on the inner face of a pipe, the water sealing agent is cured by a lamp, and excess heat generated by the lamp is efficiently released to the outside of the device, and also water in the pipe is prevented from infiltrating into the device and reliability is high.
SOLUTION: A flexible cylindrical pressure body 5 is arranged between a pair of mutually separated side covers 7, 7a of the body. An airtight vessel 1 having light transmission and rigidity is held in the flexible cylindrical pressure body 5. A lamp 2 is arranged in the airtight vessel 1 and both an air supply passage 19 and an exhaust passage 19a are perforated in the side cover 7 on one side. The air supply passage 19 is opened in one end of the airtight vessel 1 and also the exhaust passage 19a is opened in the other end of the airtight vessel 1. Furthermore, pressurized air is encapsulated to the inside of the flexible cylindrical pressure body 5 so as to freely come in and out through the side cover 7 on one side. Control of air in the inside of the flexible cylindrical pressure body 5 and control of flow of air in the inside of the airtight vessel are performed individually and independently.
