Infrastructure Bridges

Bridges serve as vital arteries within the framework of our infrastructure, functioning as essential connectors that facilitate the flow of commerce, contribute to economic vitality, streamline transportation networks, and guarantee safety and dependability.

The strategic importance of bridges in the context of road traffic cannot be overstated, as they are critical junctures where the principles of stability, durability, and safety intersect. These structures are designed to withstand not just the constant burden of vehicular load but also the stresses imposed by natural elements over time.

With climate change contributing to the increased incidence of extreme weather patterns, the urgency for implementing advanced drainage systems in bridge design has become more pronounced. Efficient and responsive drainage infrastructure is crucial to avert the accumulation of surface water that can precipitate hazardous conditions, such as aquaplaning or the formation of black ice, which significantly heighten the likelihood of traffic incidents.

Furthermore, the longevity of bridge structures is intricately linked to the effectiveness of their drainage systems. Stagnant water can lead to accelerated deterioration of materials, compromising the integrity of the bridge and resulting in costly repairs and maintenance.

It is essential to equip these structures with robust and reliable drainage systems that can contend with both present demands and future challenges, ensuring the continuous and safe transit of vehicles and pedestrians. This commitment to excellence in bridge infrastructure underscores our dedication to public safety, economic efficiency, and the longevity of our built environment.

Space constraints on bridges require efficient drainage solutions, influenced by construction height limitations. Optimal design is crucial, as minimizing concrete or steel usage can lead to significant cost savings.

ACO Multitop bridge gullies are designed to meet the special requirements during the construction and renovation of bridges and pavements. They enable significant improvement in the function, safety and economic efficiency of drainage. Special solutions are offered for all relevant areas of use.

ACO Multitop HSD

ACO Multitop HSD bridge gullies offer enhanced functionality, safety and efficiency. Their height-adjustable (H), laterally displaceable (S), and rotable (D) upper parts, along with screwless locking gratings and damping inserts, ensure seamless operations.

The closed-frame design facilitates easy installation, with customizable drainage options.

Maximizing water absorption with a flat design was paramount. Clients, planners, architects, and bridge operators sought to minimize gullies and penetration through structures, ensuring efficient drainage from roadways, even with slight longitudinal gradients. This demand led to the development of a new linear drainage solutions for bridges.

ACO KerbDrain Bridge represents an innovative 2in1 kerb channel solution, seamlessly integrating border stone/kerb functionalities with drainage capabilities.

Surface water is efficiently absorbed through lateral inlet openings and drained via the channel´s hollow space, despite its compact design, offering excellent drainage capacity suitable for class D 400 requirements.

Positioned in non-trafficked cap areas, it provides powerful drainage with a low longitudinal gradient, Enhancing safety and durability by minimizing penetration in bridge construction.

The integrated seal ensures extended protection, making it suitable for both renovation and new construction projects, including motorways, trunk roads, and urban bridges.

Additionally, a version with a second drainage level caters to bridge designs with porous asphalt (OPA), effectively managing water infiltrated through the asphalt layer.

Bridges that span watercourses carry a dual responsibility: ensuring the safety and smooth operation of traffic and minimizing their environmental footprint. It is critical to address the environmental impact of water run-off from these structures, as it often carries potentially harmful substances into the surrounding ecosystems.

When the discharge of water from bridges into natural water bodies is inevitable, it is advisable to implement systems designed to treat the water. Such systems should effectively remove sediments, heavy metals, particles from tire and brake wear, exhaust emissions, and other automotive pollutants.

The strategic installation of sedimentation units, in combination with light liquid separatorsor filters for heavy metal adsorption, enables the effective pre-treatment of large volumes of water. These systems work together to reduce the concentration of pollutants, ensuring that the water discharged into watercourses meets environmental standards and does not compromise the ecological balance.

Incorporating these water treatment strategies not only safeguards the health of aquatic systems but also advances wider environmental conservation efforts. This strategy harmonizes infrastructure expansion with ecological objectives, guaranteeing that bridge construction is in balance with the natural environment.

For bridge applications, the use of stainless-steel pipes is critical for ensuring structural integrity and safety. Our stainless-steel drainage solutions, specifically designed for bridges, feature matte surfaces to prevent light reflection and enhance traffic safety by reducing glare for drivers. We offer large-dimension pipes, including DN250 and DN315, which are essential for creating a robust drainage network capable of handling significant water flow effectively.

ACO pipes are engineered for seamless integration within the bridge's infrastructure, allowing for the implementation of special branches with substantial reductions, such as from DN250 to DN50. This design facilitates the connection to auxiliary drains without necessitating complex reductions, thereby optimizing space, enhancing connectivity with the main drainage system, reducing the number of joints required, and ultimately lowering both labor and material costs.

The material selection for these pipes, specifically stainless-steel grade 316L (1.4404), is deliberate to ensure compatibility with the bridge's concrete structure, given their similar expansion properties. This choice negates the need for special expansion treatments, except at the bridge terminations where transitions to supports are managed. The 316L grade is also preferred for its increased resistance to chloride, offering durability against the corrosive effects of winter salting and ensuring the longevity and reliability of the drainage infrastructure on bridges.
