Design concept of trough bridge

The design concept of trough bridge mainly includes the following aspects:

Protect the cable: The trough bridge adopts a fully enclosed design, which can effectively protect the cable from external dust, rain, and corrosive gases. It is particularly suitable for chemical plants, coastal areas and highly corrosive environments. This design can also prevent external electromagnetic interference and is suitable for communication and power control systems.

Thermal expansion and stress management: In high temperature environments, materials will undergo thermal expansion. If the design is not appropriate, it may cause damage to the bridge structure. Therefore, fire-resistant trough bridges usually reserve a certain amount of thermal expansion space in the design, or adopt special connection structures to cope with the stress caused by thermal expansion.

Modular design: Some trough bridges adopt modular design, which is convenient for production, processing, transportation and installation. For example, the fire-resistant trough cable bridge is composed of multiple modules, which solves the inconvenience of existing integrated cable bridges in production, transportation and installation.

‌High strength and stability‌: Trough-type bridges are usually made of steel or fiberglass, which have high strength and rigidity and can withstand large loads, ensuring the safety and stability of cable laying. Its unique trough design and solid material enable the bridge to maintain the integrity of the overall structure when subjected to external impact, reducing the risk of cable damage‌.
