REINFORCED WALL STRUCTURES

DECEMBER 2010

In 2006 VSL Middle East were awarded a tender to construct 92,000m2 of retaining wall on the Muscat Southern Expressway in Oman. VSL’s engineers determined that the optimum solution was to build the retaining walls using VSL’s VSoL® Polymeric Walls System. VSoL® Polymeric Wall’s consist of precast concrete facing panels which are attached to high strength PARAWEB® reinforcement strips. The PARAWEB® strips are covered and compacted with a backfill material. PARAWEB® reinforces the structure by transferring the load from the fill material via frictional interaction. VSoL® walls up to 56m high have been built by stacking layer upon layer of interlocking concrete panels.

PARAWEB® and PARALOOP® are integral components in the VSoL® Polymeric Wall System. PARALOOP’s are cast in to the concrete pannels in parallel sets of two. High strength composite pins are secured between the loops and PARAWEB® reinforcement strips are wrapped around the pins. The PARAWEB® reinforcement strips are then buried in a compacted fill material.

REINFORCED WALL STRUCTURES

DECEMBER 2010

A Member of the Maccaferri Group

The Southern Expressway project used 30, 50 and 70kN (NBL) PARAWEB® type 2D. This particular type of PARAWEB® was selected by design engineers due to its durable polymeric sheath. 70kN PARALOOP’s were used alongside the type 2D PARAWEB® strips.

PARAWEB® and PARALOOP’s have a high ultimate tensile strength, low elongation, excellent creep strain properties and high resitance to environemntal and chemical attack. The combination of these properites make PARAWEB® and PARALOOP ideal anchorage and reinforcement materials for MSE wall systems.

Due to the technical and economic merits of the PARAWEB® reinforced VSoL® polymeric wall system, additional walls were awarded to VSL during the construction phase of the project. In total over 108,000 m2 of PARAWEB® reinforced wall was installed on the Muscat Express Way.

The largest wall on the project comprised of two 56m high back to back tiered walls, built to provide a road embankment for a wadi crossing. These walls are the highest MSE walls built to date using PARAWEB® reinforcement strips. The Southern Expressway project marked the first project in which PARAWEB® and PARALOOP’s were used as reinforcement elements within VSL’s VSoL Polymeric Wall System.
