Furthermore, the number of the reinforcing ribs in each reinforcing pipe section is at least three.
Further, at least two general sections are arranged between the two reinforcing sections.
Further, the convex plate is in a quadrilateral, hexagonal or octagonal structure.
Further, the projection of the pipe body on the vertical plane exceeds the projection edge of the convex plate.
Further, the flange includes polygonal flange main part and the arc portion of shaping in flange main part periphery, the flange main part is opened there is the arc chamfer.
The utility model has the beneficial effects that: the polypropylene high-reinforcement polyethylene composite special-shaped corrugated pipe is provided with the convex plates, and the convex plates have the function that after the pipe is buried, the filler can be filled in the space between the convex plates, so that the pipe body is fixed in the filler, and the axial deviation of the pipe body is prevented. The groove on the outer peripheral surface of the convex plate can be filled with the filler after the pipe is buried, so that the stability of the pipe body in the axial direction is further improved, the groove is also favorable for dispersing the pressure of the filler on the convex plate, and the deformation possibility of the convex plate under the extrusion action of the filler is reduced. The trachea can inflate the flange in process of production and make it form hollow structure, and the trachea structure also plays the effect of strengthening to the body to a certain extent simultaneously, and the stiffening rib of cooperation in the section of strengthening simultaneously can further improve its reinforcing effect to the structure. The reinforced pipe sections are distributed at intervals, so that the production cost can be reduced to a certain extent on the premise of less influence on the structural stability.
