Competitive Price Combi-Wall Systems Pipe Combination Wall Series Piling Walls
A Combi-wall is a combination of large-diameter steel pipe piles and sheet piles installed to form a retaining wall structure. Pipe piles provide resistance to overturning forces and the steel sheet piles serve as in-fill between the pipes. Combi-walls can be left in place permanently or elements can be extracted and re-used when no longer needed.
The pipe pile portion of a Combi-wall is typically installed as a bored pile which may or may not be backfilled with concrete and reinforcing steel, depending on the application. Sheet piles are installed in the spaces between the pipes with a vibratory hammer and are aligned with pipes using welded interlocking points.
Advantages
*Combi-walls provide a cost-effective shoring alternative to the secant wall while providing significantly more load bearing capacity than a sheet pile wall.
*Combi-walls are effective in temporary applications as the steel elements can be easily removed and re-used once the structure is no longer needed.
We are capable to offer the complete solution for combi wall systems.From high section modulus to relatively low mass ratio, endless combinations allow for the most economical solution to be adopted - U or Z type sheet piles can be used as infill, with the interlocks welded to the tubular piles ready for installation, giving freedom of choice for customers depending on preference and cost.
The tubular piles can have thicknesses up to 120mm, diameters up to 4000mm and lengths up to 120 meters, manufactured by SSAW or LSW method in accordance to relevant standards such as ASTM A252, with interlocking hot or cold rolled clutches welded at request. Steel grade:from grade B to X65 X70,S235 to S420 S460 etc.
