Title:
REPAIRING DEVICE OF INSTALLING PART OF MANHOLE BOTTOM SIDE PART AND CONDUIT
Document Type and Number:
Japanese Patent JP3281303
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To reliably repair an installing part of a manhole bottom side part and a conduit by fixing a repairing device to the installing part of the manhole bottom side part and the conduit, inflating a press-fitting means with air, and press-fitting a repairing material impregnated with a resin binder installed on the outer periphery to the installing part.
SOLUTION: An air filling port 4 to inflate it by blowing in air is arranged in pressurizing tubes 2 and 3 of a pressurizing/press-fitting means. An air filling port 7 is arranged in a fixing means 5 of the pressurizing/press-fitting means. A hard acrylic resin is used as a construction material of a cylindrical body and a semicylindrical object. A repairing material 8 is formed in a mat shape by impregnating an underwater hardening resin binder into, for example, carbon fiber. This repairing material 8 is formed in the shape of joining an opening cylindrical object and a semicircular collar on the left and of the upper part to be installed on the outer periphery of a press- fitting means. When the press-fitting means is inflated with air, it is reliably raised up together with expansion of the press-fitting means to steadily pressurize the inside of a conduit, and the repairing material 8 can be reliably brought into close contact with an installing part.
