Professional Bridge Formwork Tech
Concrete beams with a T-shaped cross-section (mostly precast prestressed concrete beams) are the most commonly used main girder type for highway and railway bridges.
Efficient load-bearing: Concrete resists compression while reinforcing bars/strands resist tension, resulting in high material utilization
Widely used in various bridge projects, including highway bridges, railway bridges, urban elevated bridges, overpasses, and municipal landscape bridges
Piers are the central vertical load-bearing elements in bridge engineering. Located between the bridge foundation and the superstructure (including the beams and deck), they play a crucial role in connecting the upper and lower structures and are a core component in ensuring the overall structural safety of the bridge.
The foundation primarily bears the entire load from the bridge’s superstructure—including the beams, deck, and traffic—and transfers this load smoothly to the bridge’s footings, where it is then distributed into the ground.
Excellent load-bearing capacity: Strong vertical load-bearing capacity, high structural rigidity, stable and reliable load-bearing performance, and minimal deformation;
Cylindrical piers: Distribute loads evenly and are easy to construct; they are suitable for conventional highway and railway bridges and are the most widely used;
High adaptability: Flexible and diverse design options that can be tailored to bridge spans, terrain, and landscape requirements;
Bent cap, also known as cap beam, is a transverse load-bearing component installed on the top of bridge piers, arranged between piers and upper beam slabs for force transmission. It is generally of reinforced concrete structure and cast-in-situ with steel formwork at the construction site.
Widely used in various types of bridge engineering, it is a standard component for small- and medium-span bridges, elevated expressways, interchanges, and municipal bridges. It is particularly indispensable in bridges with multiple piers and serves as a critical component of the bridge substructure.
Most have rectangular, trapezoidal, or vase-shaped cross-sections, featuring a simple design and clear load-bearing characteristics.
Connect and secure multiple piers to enhance the structural integrity and lateral stability of the bridge substructure.
Directly support superstructure elements such as T-beams, box girders, and hollow-core slabs, evenly distributing the deck load to the underlying piers and foundations.
Convenient Construction: Utilizes prefabricated steel formwork, which is easy to install and dismantle, resulting in high-quality concrete finishes.
Hanging basket, fully named cantilever casting hanging basket, is a special mobile construction equipment for long-span bridge box girder construction. It is mainly applied to cantilever casting construction of viaducts, continuous beam bridges and river-crossing & sea-crossing bridges, enabling sectional forward construction along the bridge axis without temporary supports.
