- • Our RCC HDPE Lined Jacking pipes are available in various diameters, typically ranging from 600 mm to 2600 mm, to cater to different project requirements.
- • RCC HDPE Lined Jacking pipes are designed for trenchless installation methods, meaning they can be laid without the need for extensive excavation. This is a cost-effective and environmentally friendly method.
- • The pipes are made from reinforced cement concrete, offering strength, durability, and resitance to external pressures.
- • The inner surface is lined with HDPE to protect against internal corrosion, abrasion, and other environmental factors.
- • These pipes are used primarily in sewerage, stormwater, and wastewater applications where open excavation is impractical or impossible and internal resistance to corrosion are required.

2. Design and Manufacturing
- • • Material Composition: The concrete is reinforced with steel bars or mesh to withstand both internal and external forces, including earth pressure, water pressure, and mechanical stresses.
- • Jacking Forces: The design also takes into account the forces involved during the jacking process, which includes both the pushing force and the frictional resistance from the surrounding soil.
- • HDPE Liner Thickness: The thickness of the HDPE liner is designed based on the expected chemical exposure, pressure, and flow conditions. It provides a non-corrosive barrier to protect the RCC from aggressive environments.
- • MS or SS Collar: Mild Steel or Stainless Steel Collars are used in place of conventional Concrete Collars to withstand the forces involved during the jacking process.
- • Jointing Methods: The pipes are designed with specialized joints, such as bell-and-spigot or rubber-ring joints, to ensure watertight and durable connections between pipes.
- • The jacking method involves the use of hydraulic jacks to push the pipes through the soil from a starting shaft to a receiving shaft.
- • The method reduces the need for extensive surface disruption, making it ideal for urban areas or places where surface access is limited.
