Loading hole prefabricated pipe fitting for reaction wall construction and reaction wall construction method

The invention relates to the technical field of reaction wall construction, in particular to a loading hole prefabricated pipe fitting for reaction wall construction and a reaction wall construction method.The loading hole prefabricated pipe fitting comprises a steel pipe, end plates are arranged at the two ends of the steel pipe, and a channel steel positioning frame used for positioning the position of a loading hole is arranged in a reaction wall; the channel steel positioning frame is formed by welding a plurality of longitudinal channel steel and transverse channel steel which are staggered transversely and longitudinally, a positioning steel plate is arranged on the steel pipe, one side of the positioning steel plate abuts against and is fixed to the longitudinal channel steel, and the other side of the positioning steel plate abuts against and is fixed to the transverse channel steel. The steel pipe is positioned and fixed through the channel steel positioning frame and the positioning steel plate, err
