The invention discloses a bamboo-joint-shaped prestress flat opening plastic pipe, which is formed by sequentially connecting a plurality of pipe sections with the same structures, wherein each pipe section comprises a large flat opening pipe, a small flat opening pipe, a medium flat opening pipe and a small flat opening pipe which are sequentially connected; the left and right sides of the cross section of each of the large flat opening pipe, the medium flat opening pipe and the small flat opening pipes are mutually parallel straight pipe walls; the two ends of the two straight pipe walls are connected with semicircular pipe walls; the straight pipe walls and the semicircular pipe walls have the same thickness; and the contour sizes of the cross section of the large flat opening pipe, the cross section of the medium flat opening pipe and the cross sections of the small flat opening pipes are sequentially decreased. The bamboo-joint-shaped prestress flat opening plastic pipe has the beneficial effects that the bamboo-joint-shaped prestress flat opening plastic pipe is suitable for vacuum grouting post stressed concrete construction; the prestress pore passage grouting density and the prestress pore passage grouting saturation degree are ensured; the damage-resistant performance is high; the contact area with the concrete is increased; the force transmission reliability of a prestressed steel strand to a concrete component after grouting is facilitated; and the bamboo-joint-shaped prestress flat opening plastic pipe is used for being embedded in a small-thickness component.
