Advantageous effects

In conclusion, the utility model has the following beneficial effects:

1. this strenghthened type polyethylene winding pipe, go up the first recess and the second recess of the interior leanin of protective layer and form triangle form, when this strenghthened type polyethylene winding pipe when pressurized its power that receives spreads to whole spiral reinforcing section bar that bears on, be equipped with the spiral reinforcing section bar formation triangle of V-arrangement backup pad and last inoxidizing coating in the lower inoxidizing coating, including the cavity at V-arrangement backup pad both ends, make up the extrusion force that the inoxidizing coating received on the stress surface supports, be equipped with the steel strip in its V-arrangement backup pad, and square steel strip not, thereby cost greatly reduced.

2. This strenghthened type polyethylene winding pipe can deform when receiving the extrusion force, because first recess and second recess are that the leanin sets up and closely laminate, be unlikely to like the square groove can grow the clearance for the condition of two adhesive connection's gluey ftractures produces.
