Our jacking GRP pipes are engineered for trenchless installation, offering high longitudinal compressive strength and lightweight handling. The manufacturing process includes precision filament winding, length cutting, end preparation, and joint assembly-ensuring dimensional accuracy and reliable sealing under jacking thrust. They are the cost-effective solution for trenchless environments where traditional open-cut methods are restricted or economically unfavorable.
1. Pipe manufacturing by continuous filament winding process
2. Pipe cutting
3. Joint processing
4. Joint / coupling installation
What are the typical applications for pipe jacking?
1. Trenchless installation where open-cut excavation is not feasible.
2. Deep burial conditions where conventional open-cut becomes economically unviable.
FAQ
Q: 1. What are the main categories of jacking GRP pipes?
A: Non-pressure jacking GRP pipes and pressure jacking GRP pipes.
Q: 2. What are the advantages of continuous filament-winding jacking GRP pipes over steel pipes and reinforced concrete pipes?
A: They offer higher allowable jacking force, better performance in soft foundations with less tendency to sink or tilt, lower soil friction, superior hydraulic characteristics, and excellent corrosion resistance.
Q: 3. What materials are suitable for non-pressure jacking GRP pipe couplings?
A: Carbon steel, stainless steel, and GRP/FRP.
Q: 4. What factors influence the jacking distance?
A: Allowable jacking force, soil type, and construction experience.
