Abstract

A device for automatically reinforcing a transmission tower foundation damaged after a lightning strike and a method for using the device include a liquid seepage pipe, a liquid storage box, reinforcement bars, and a push rod. The liquid seepage pipe is vertically inserted into the interior of the transmission tower foundation. A liquid seepage hole is formed on the side of the liquid seepage pipe. The liquid storage box is installed in the liquid seepage pipe. The liquid storage box is filled with adhesive. A liquid flow hole is formed on the side of the liquid storage box. The push rod slides vertically to connect to the liquid storage box and is connected to a baffle at the lower end. The baffle abuts against the inner wall of the liquid storage box. The upper end of the push rod passes through the liquid storage box, the liquid seepage pipe, and the transmission tower foundation and is connected to the end of the reinforcement bar. The reinforcement bar is annularly wrapped around the outer side of the transmission tower foundation. The present invention achieves an automatic reinforcement effect by annularly wrapping the reinforcement bar around the outer side of the transmission tower foundation. When the volume of the transmission tower foundation expands after a lightning strike, the push rod is pulled upward, thereby discharging the adhesive. The adhesive penetrates from the liquid seepage pipe into the cracks in the transmission tower foundation caused by the lightning strike, thereby achieving the effect of automatic reinforcement.
