MultiRio Container Terminal

MultiRio Container Terminal

The MultiRio Container Terminal is a large container terminal located in the Rio de Janeiro Port. The terminal specializes in the import/export of finished goods.

MultiRio plans to increase its shipping capacity by at least 50% and launch in 2012 an expansion project aiming at adding extra quay length to its infrastructure in order to receive additional port containers.

To support the pier expansion of MultiRio, Dextra has been working with contractor Andrade Gutierrez for the engineering and supply of Marine Tie Rods.

Dextra supplied in 2014, 100 tons of steel rods coming in medium diameters M56 and M59. The rods were anchored to the wall by the use of swivel plates and nuts, which conveniently allow 5° multidirectional adjustment.

Plates are positioned onto the Waling beams, also supplied by Dextra. Waling beams are installed onto the sheet piles. Their design is directly impacted by the Tie Rods solution chosen as for example spacing of the beams will be impacted by the diameter of the bar and angle of the rod.

Altamira Port – Multiple Use Terminal Expansion

Altamira Port – Multiple Use Terminal Expansion

Altamira Port is located on the shores of the Gulf of Mexico in Altamira Tamaulipas and connects with 125 ports across the world. The port services an important area of economic and industrial activity in the country. It handles liquid and dry bulk, petrochemicals, LNG, container, and general cargo.

The expansion of the multiple use terminal of the Altamira Port is part of the plan to make Mexico a global logistics platform. Dextra marine tie bars were chosen to anchor sea walls during the expansion. 174 tons of tie bars in grade 700 were supplied.

Moreover, Sonitec, a sonic tube solution, was used for the CSL (crosshole sonic logging) testing of foundation piles of the quay. It facilitates the structural integrity and homogeneity of concrete within the piles by measuring the speed of ultrasonic pulses.

Sète Port

Sète Port

The Port of Sète is a large sea port opened to the Meditteranean Sea. It is the largest fishing port in the South of France. It also serves many ferry connections towards Tangiers and other destinations in North Africa.

Sète Port and its main sponsor, Region Languedoc Rousillon, wish to increase the container capacity of the port by adding a new quay (Quay H, 15 meters deep) to their existing infrastructure. The new quay will increase both handling and storage capacity of containers.

To support contractor Soletanche-Bachy in the construction of this new structure, Dextra engineered and delivered 74 Marine Tie Rods assemblies. The tie rods systems delivered are the largest currently available in our range: M160.

Large diameter assemblies allow to reduce the number of sets which need to be installed by increasing the spacing between each rod.

The long tie rods assemblies were anchored into the D-Wall by the installation of ball cages, which allow a rotation angle of 10° in all directions.

The Ball Cages were installed into reinforcement of the D-Wall and cast in concrete. After excavation, ball cages were open to allow the reconnection of the threaded ends of the rods.

Grand Paris Express – Line 14

Grand Paris Express – Line 14

The Grand Paris Express is a major urban transport project taking place all around the French Capital. The project will add 4 new lines (lines 15, 16, 17 and 18) and extend two existing lines (11 and 14).

Dextra has been involved on the packages of several stations through its local distributor partners. On the line 14 in particular, Dextra supplied Fortec rebar couplers in stations of Orsay and Pont Cardinet.

For the Bagneux Station in the North of Paris, located at the crossing of metro line 4 and future line 15, Dextra supplied its ASTEC Active Anchors.

ASTEC Active Anchors are the preferred solution for subway stations works as Tunnel Boring Machines and earth-moving equipment can simply cut the anchors’ FRP tendons at any stage, eliminating any need of unreliable and costly removal of anchors. The solution was approved for this project by consulting firm SYSTRA.

After numerous successful projects in the Middle East, this was the first time ASTEC Active Anchors (a recent Dextra innovation) were installed in Europe.

New Bay Bridge of San Francisco

New Bay Bridge of San Francisco

The New Bay Bridge is a large civil engineering project taking place between the years 2002 and 2013. The aim of the project was to replace two segments of the Bay Bridge vulnerable to eathquakes by a new structure designed to withstand seismic efforts.

For that project, Dextra was involved on two segments of the renovation project: the approach to Bay Bridge on the San Francisco side, and the Eastern segment from the Island of Yerba Buena to Oakland.

Dextra supplied for this project its Bartec Headed Bar systems. Headed Bars are an anchor disc mounted on the end of a rebar previously prepared for the Bartec system.

The use of Headed Bars provides an smart and compact alternative to long rebar hooks in areas where the reinforcement is particularly congested. Unlike hook bars, Headed Bars are particularly easy to install, as end anchors can just be screwed onto the reinforcement at a later stage, after the reinforcement is installed.

For the approach to the Bay Bridgee in San Francisco and the Yerba Buena Eastern Segment, Bartec Headed Bars were used for the shear reinforcing of the column foundations, as well as in the bridge hinges.

The Bartec Headed Bars solution is approved by CALTRANS, the California Department of Transportation, for all imperial bar size #3 to #18. and is also certified by the ICC-ES.

Hanoi Nhật Tân Bridge

Hanoi Nhật Tân Bridge (Vietnam – Japan Friendship Bridge)

The Nhat Than Bridge is an impressive cable-stayed bridge spanning over the Red River and located North of Hanoi. The total length of the project is 8.9 km, including the actual3.75 km bridge.

The bridge is the new gateway to Hanoi as it greatly reduces the transport time to Hanoi Noi Ban Airport, the second busiest airport of Vietnam in passengers.

The bridge was inaugurated by the Ministry of Transport of Vietnam and opened to the public on the 4th of January 2015. The bridge has since theen been renamed “Vietnam – Japan Friendship Bridge).

Dextra has been involved on the Nhat Tan bridge since the early stage of the project by supplying the popular Bartec rebar couplers, the main rebar splicing solution in Vietnam. Bartec connections were used in various part of the project: approaches, foundation piles, pile caps and approaches.

Bartec couplers make a convenient rebar splicing solution as the same standard coupler can be used for standard connection (rotating rebar into coupler) and position connection (rotating only coupler, when it is impossible to rotate rebar). Dextra supplied more than 130,000 connections in total for this project for the lifting of heavy elements.

For the temporary operations of lifting and fixing of the girder precast segments, Dextra also supplied 36 tons of high-tensile PT bars.

Cartagena Viaducto Del Manglar

Cartagena Viaducto Del Manglar

The Viaducto del Manglar project is a 5.3 km bridge project spanning over the Ciénaga de la Virgen (swamp), north of the City of Cartagena, Colombia. The project aims to reduce traffic congestion when exiting the city in the Zona Norte (North Area).

The viaduct, which aims for opening in 2018, is part a longer highway project linking the city of Cartagena with the city of Baranquilla.

For this project in Colombia, Dextra has been supplying contractor Rizzani de Eccher with Rolltec rebar couplers and Headed Bars. Rebar preparation operations has been performed by Dextra distributor in Colombia.

Headed Bars were used in precast caissons, installed below the bridge girders, as a way to reduce steel congestion in the heavily reinforced steel cages.
