Abstract
A support tool for leakage repair of an inspection well includes: a curved loading plate having multiple grouting holes thereon, a telescopic adjustment device, and a base; wherein: one end of the telescopic adjustment device is connected to an inner side face of the curved loading plate, and the other end of the telescopic adjustment device is connected to the base; the telescopic adjustment device adjusts a distance between the curved loading plate and the base. The support tool is firstly hoisted at a leakage position of the inspection well; then a telescopic length of the telescopic adjustment device is adjusted, so that the curved loading plate and the base are in a close contact with opposite sides of the inspection well wall; and a grouting system is used to inject a double-slurry quick-setting repair material into a grouting pipe on the curved loading plate for plugging leakage.
