METHOD AND DEVICE FOR REPAIRING WATER LEAKED/WATER INTRUDED SECTION

摘要

PURPOSE:To inject filler properly without causing further damage by detecting the pressure at a filler injecting section and controlling the pressure. CONSTITUTION:An injecting member 18 is provided with a pressure sensor 38 for detecting the filler injecting pressure. Another pressure sensor 41 is arranged at the outlet section 40 of a pump 25 for pressure feeding the filler in order to know the original feeding pressure. When the working pressure of filler drops to a low setting level because of the breakdown pressure of a member at a repairing position, pressure feed of filler is stopped. By such arrangement, breakdown due to filler at a repairing position can be prevented.
