Prefabricated rectangular jacking pipe and construction method thereof

The invention provides a prefabricated rectangular jacking pipe and a construction method thereof and relates to the technical field of jacking pipe engineering. The construction method comprises thefollowing steps of S1, prefabricating a U-shaped splicing segment, wherein the U-shaped splicing segment is provided with two parallel arms, and channels penetrating corresponding arms are arranged inthe two arms; S2, splicing the U-shaped splicing segment to form a pipe joint, specifically, splicing a plurality of U-shaped splicing segments end to end successively to obtain a pipe joint of a closed structure; and S3, splicing the pipe joint to form the jacking pipe, wherein the end to end splicing specifically comprises inserting an anchoring rod into each channel, and fixedly connecting theanchoring rods in the U-shaped splicing segments to be spliced end to end to obtain the annular pipe joint. In a pipe jacking process, splicing in the pipe joint is finished by stretched anchoring rods, and the stretched ancho
