Construction—South America—Peru—Slope Stabilizations
Reliable Slope Stabilization with DYWIDAG Strand Anchors:
The Large-Scale Project Costa Verde del Callao
The large-scale project Costa Verde del Callao is being constructed between the district of La Punta in the seaport of
el Callao and the coastal district of Chorrillos southwest of Lima, Peru. A new, 5.8km long expressway is being built in
this area to improve the connection with Jorge Cháves Airport and to reduce travel times from La Punta to Chorrillos to
25 minutes.
The new road includes 3 lanes per direction
and is built directly along the coast on a man-
made landfill. Within the scope of the project,
connecting roads are being built for the Santa
Rosa and Haya de La Torre roads that consist
of access ramps and viaducts.
Comprehensive slope stabilization was
required in order to build these viaducts.
The subcontractor Mota-Engil awarded
DSI Construction Peru the contract for
supplying permanent, Type 4-0.6" DYWIDAG
Strand Anchors for the long-term stabilization
of the sidehill cuts.
170
A total of 60 DYWIDAG Strand Anchors were
installed in 4 layers to tie back the slopes
at both viaducts. 49 DYWIDAG Strand
Anchors with 4 load cells were installed in the
sidehill cut for the Haya de la Torre Viaduct.
11 DYWIDAG Strand Anchors and 1 load cell
were required for stabilizing the Santa Rosa
Viaduct. The permanent strand anchors had
lengths of 14.5-19m.
