step four: fixedly connecting a flange with a bar-planting bolt, and welding the flange with a short steel pipe, wherein a preservative is coated at the joint of the flange and the concrete pool wall;
step five: and connecting a valve to the other end face of the flange, connecting a tapping machine to the other end face of the valve, then performing online tapping operation, and taking out the residual concrete in the mounting hole by using the tapping machine to complete the online tapping operation of the concrete pool wall.
