    Infrastructure projects

This category of applications concerns a range of development projects which is essential for economical development. The usage of our products is usually very attractive considering the ability to re-use and recycle steel products and its consequential beneficial effect to the total life cycle costs. 


Canals and rivers

Canals and rivers are waterways often used for navigational purposes. The main difference between them is that one is man-made and the other one is eroded naturally throughout time. The transportation capacity of the waterway is determined by its depth and width.

As the regions tend to develop their transportation capacity, waterways need to be deepened. This has an impact on the retaining height of both embankments and berthing facilities, but also at the structures needed for to regulate the navigation like locks sluices and weirs. Our large range of sheet piles including cold and hot rolled sheet piles enable designers to choose for an optimal and cost efficient solution. 


Shipping locks

Shipping locks are infrastructural structures built to overcome differences in water levels or quality within a river or canal.

Sheet piles, tubes, beams, or anchoring systems can be used to realize a competitive alternative to other building methods.


Tunnels

Tunnels are constructed at locations with limited possibilities at the surface. Several different construction methods can be used for the execution of a tunnel depending on the soil conditions and other environmental aspects. Shallow tunnels are often constructed using the cut-and-cover method.

This is a simple method of construction for tunnels in which a trench is excavated and subsequently roofed over with an overhead support system strong enough to carry the loads coming from above. In the case of an immersed tunnel sheet pile structures are often used to construct the entrances of the tunnel and the dry dock used for the prefabrication of the tunnel elements.

Similar structures are needed for bored tunnels. Besides the entrances a deep shaft is needed in which the boring machine can be set up and can start its activities. The construction of such shafts are often realized using sheet piles, beams and tubes to build a structure similar to a building bit or cofferdam.


Highways and railway foundations

Highways and railways form the back bone of a infrastructural network. The tolerances on settlements and displacements are very strict as it has a direct influence on how sustainable a structure is.

Steel materials such as sheet piles, piles, and tubes are the products of choice to realize a stable foundation that enable the designs to be space saving and multifunctional when needed. Especially at infrastructural nodes a variety of our products can be applied in the design.


Bridges

Bridges are built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. Many different designs are possible that all serve unique purposes and apply to different situations. Designs of bridges vary greatly depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the materials used, and the funds available to build it.

One common element to all bridge designs is that the foundation has to bear concentrated loads and thus needs to be very stable. In many situations this implies very deep foundations at different locations and environments. Part of these foundations are the abutments needed at each end of the bridge to enable a rapid change in elevation of he supported infrastructure.

As they are usually constructed in densely urbanized areas the designer faces challenges when putting all requirements together. Usually sheet piles and combined walls are used  as they can provide several functions as (temporary) earth retaining structure, foundation and structural elements.


´╗┐Impervious containment

Impervious containment walls, also called bund walls, are a constructed retaining wall designed to prevent inundation or breaches from a known source. It is a secondary containment system commonly used to protect environments from spills where chemicals are stored. Sheet piles have been used for many years to construct water retaining cofferdams.

In recent years the same flow-restricting properties have been used in the environmental sector. Sheet piles can be driven deep to cut off groundwater far below the surface. Sheet pile barrier walls are far less disruptive than slurry walls, drilling and other methods. The inherent tightness of the Larssen interlock of the sheet piles, the width of the piles, and the possibilities for prefabricated sealing and welding measures all contribute to decrease a possible flow.

Sheet piles are recognized by environmental engineers as an excellent method for containing spills and polluted ground water and have enjoyed success in many environmental projects.


Noise barriers

Noise barriers are exterior structures designed to protect inhabitants of sensitive land use areas from noise pollution.

They are the most effective method of mitigating roadway, railway, and industrial noise sources.


Trenches

Trenches are excavations in the ground that are generally deeper than its width. In the civil engineering field of construction or maintenance, trenches are created to install or search for underground infrastructure or utilities (such as gas and water pipe lines or telephone lines, etc).

The construction of a trench is usually done in an environment with limited space and sheet piles are an ideal solution to dig a trench under a steep slope with limited occurring displacement in the environment while providing a dry construction space at the bottom of the trench. In the situation the trench is dug to build a fluid transportation network steel tubes are an ideal product to enclose the transported material. Whether they are carrying clean potable water for domestic or industrial consumption, or discharging wastewater from a residence, transmission lines are essential to keeping the system operational. Steel pipe has been recognized by engineers as one of the most reliable products for this application.
