　　Design Theory and Construction

　　This product belongs to flexible pipeline and rigid pipeline,which are obviously different in design.For rigid pipeline,it is usually regarded as an independent bearing structure,that is,between pipeline and fill,because of the mutual transfer of force and the coordination of deformation,the two are combined into a highly effective overall structure.

　　In the engineering application of winding reinforced pipe,the density of the bottom cushion and backfill determines the load capacity of the system and the radial deformation rate of the pipe.Therefore,backfill is required to achieve the required density(generally 95%)to ensure the safe operation of the project.
