Uneven conjoined double-walled sewers method for improving the strength and cohesion

摘要

The present invention relates to a double wall sewer pipe manufacturing method for improving rigidity and bonding force. More particularly, the present invention relates to a double wall sewer pipe manufacturing method, And a reinforcing connecting member having a concave-convex coupling protrusion formed at a predetermined interval by the outer diameter of the profile and the connecting member is provided to enclose the connecting member so that the reinforcing connecting member and the profile are connected to each other in a concavo- The present invention relates to a method of manufacturing a double wall sewer pipe of a concave-convex connection type for improving rigidity and bonding force for improving rigidity. The present invention is characterized in that a profile is extruded from a second extruding device 20 and cooled in a cooling device 29 and then spirally fed to a pipe making device 10 and connected between the profiles in a third extruding device 30 1. A sewage pipe manufacturing method for forming a double wall sewage pipe by supplying a member, To be cooled by the cooling device 29 from the second extruding device 20 having the hollow 22 in the inner diameter and being extruded into the extrusion molding device 40 so as to form the engaging recessed groove 27 on both sides of the outer diameter 28 , And then spirally supplying the solution to the outside of the guide roller (25) of the tube manufacturing apparatus (10); The connecting member 32 is supplied from the extrusion nozzle 31 of the third extruder 30 between the profiles 21 supplied to the pipe manufacturing apparatus 10, A joint member extruding step of molding the joint member so as to form the joint member; A connecting member molding apparatus 50 in which an engaging projection 14 is formed on both sides of the inner surface portion 15 and a reinforcing connecting member 13 forming a side projecting portion 16 is formed below the engaging projection 14, A reinforcing connecting member spirally supplying the outer diameter of the connecting member 32 and the profile 21 supplied to the pipe manufacturing apparatus 10 from the first extruder 11, And The engaging projection 14 is supplied to the lower side of the reinforcing connecting member 13 in the engaging recessed groove 27 formed in the outer diameter 28 of the profile 21 spirally supplied to the outside of the pipe manufacturing apparatus 10 Combine; One of the engaging projections 14 supplied to the upper side of the profile 21 is spirally fed to engage with one of the engaging recessed grooves 27 of the profile to be fed, (14) formed on two reinforcing connecting members (13) at outer diameters of the outer diameter (28) of the connecting protruding groove (27) and the connecting member (32) .
