GRP jacking pipe emerges as a novel form of pipe jacking, fabricated from resin, glass fiber (both continuous and short cut), and quartz sand through a continuous winding process. This pipe incorporates axial reinforced short cut glass fiber, significantly enhancing its axial compression strength.
Process Characteristics:GRP pipe jacking employs 3D printing technology, specifically the material addition manufacturing approach, to achieve continuous and rapid formation of the pipeline through a layer-by-layer superimposition method. This innovative process ensures efficient and precise production.Design Feature:GRP pipe jacking constitutes a three-dimensional reinforced pipe with a unique pipe wall structure. It simultaneously adopts two reinforcement methods: circumferential continuous fiber and three-dimensional distributed short-cut fiber. The pipe wall is seamlessly integrated into a unified whole through the short-cut fiber, effectively circumventing the drawbacks as…
