[0020] After removing the backhoe bucket, the connecting frame is installed on the bucket arm of the excavator through the fixing pin 4, and then the winch 5 is installed on the connecting frame. The winch 5 is driven by the excavator to move, and the winch is transported to the dam body. After the geomembrane roll is hoisted into place by the winch, the geotextile roll is installed on the trolley, and then the trolley is connected with the hook of the winch 5. The trolley is pulled by the steel cable to lay the geomembrane roll on the slope of the dam body.
