RD® pile retaining walls

Retaining wall structures based on steel piles

Retaining wall structures based on steel piles are often the best solution to replace traditional, labor-intensive cast-in-place based retaining wall structures.

Based on RD® piles (RD220–RD1200) and installed by drilling, RD® pile retaining walls are suitable for retaining wall structures in difficult ground conditions. The RD® pile retaining wall works extremely well in retaining wall structures that are under not only horizontal loads but also vertical loads.

Thanks to SSAB’s high-grade steel, our RD® pile retaining walls have excellent bending stiffness and resistance.

For more detailed information see SSAB’s .

Applications:

  • Retaining wall structures
  • Building foundations
  • Wharves and piers
  • Road and railway structures
  • Bridges

RD® pile retaining wall structure

The RD® pile retaining wall is a combination of SSAB's RD large diameter piles and interlocking sections.

新疆11选5RD® piles are connected by welded interlocking sections, creating a continuous pipe pile retaining wall against horizontal and vertical loads。 The RD® pile retaining wall is installed with an oversized ring bit instead of a normal ring bit。 The RD® pile retaining wall is always installed by percussion drilling methods, using a DTH hammer。 The drilling method is centric。

RD® pile pipes

Pile pipes used in RD® pile retaining walls are SSAB’s drilled RD220 – RD1200 piles. RD® drilled piles are special piles, installed by drilling in difficult ground and environmental conditions. The RD400 - RD1200 drilled piles are based on spiral welded steel pipe. The standard steel grade of RD400 – RD1200 piles is S355J2H, but grades S440J2H and S550J2H as well as X60 and X70 are also used. Pile pipes for the RD® wall are spliced by welding.

Interlocks

In the RD® pile retaining wall the pipe piles are attached to each other by interlocking sections. Adjacent piles are always interlocked using a pair of interlocking sections, a narrow and a wide one. The interlock type specially developed for the RD® pile wall is the SSAB RM/RF interlock.
SSAB’s RM/RF interlock and the injection channel integrated in it ensure the water tightness of the bottom of the RD® pile wall and its rigid contact with rock without separate injection pipes.

 

 

The SSAB RM/RF interlock can be used with pile sizes RD220 to RD1200.
