Introduction

In the fields of engineering construction, emergency rescue, and overseas infrastructure, temporary bridges play an irreplaceable role as a core hub connecting traffic and construction processes. The selection of temporary bridges directly determines project progress efficiency, construction safety, and overall cost control.

As a professional trade and manufacturing foreign trade enterprise focusing on prefabricated highway steel bridges, EVERCROSS BRIDGE TECHNOLOGY (SHANGHAI) CO., LTD. has a professional R&D bridge research center in Shanghai and a manufacturing base in Zhenjiang. Relying on advanced R&D capabilities and mature production technology, we have in-depth insights into the application needs of temporary bridges in various scenarios. Through long-term practice and market verification, Bailey Bridge (also known as prefabricated steel truss bridge) has become the unrivaled best choice for temporary bridges due to its multiple core advantages, and it is highly recognized and widely used in domestic and foreign markets.

Invented by British engineer Donald Bailey in 1938, the Bailey Bridge is a classic representative of prefabricated steel bridges, which is composed of standardized truss units, crossbeams, stringers, bridge decks, bearings and connectors made of high-strength steel. Combined with the R&D advantages of EVERCROSS BRIDGE TECHNOLOGY and the precision manufacturing capabilities of the Zhenjiang factory, the modern Bailey Bridge has been continuously upgraded and optimized, and its performance has been comprehensively improved, perfectly meeting the core demands of temporary bridges for efficiency, safety, versatility and economy.

Core Advantages of Bailey Bridge as a Temporary Bridge

1. Standardized and Modular Design: Rapid Assembly and Disassembly

The first core advantage of Bailey Bridge as the best temporary bridge is its standardized and modular design, which enables rapid assembly and disassembly. As a trade and manufacturing enterprise integrating R&D, production and sales, EVERCROSS BRIDGE TECHNOLOGY adopts a full-module standardized design system for the Bailey Bridges it operates.

Core load-bearing components such as Bailey panels, supporting connectors (pins, bolts), crossbeams, bridge decks and bearings are all prefabricated and shaped products in the Zhenjiang factory. These components have high versatility and interchangeability, and no secondary processing such as welding or cutting is required during on-site construction, realizing "immediate transportation, immediate assembly, immediate disassembly and immediate transfer".

With small hoisting equipment (truck cranes, excavator supporting spreaders) and professional construction teams, a conventional Bailey Bridge with a span of 10-30 meters can be assembled in one day and put into traffic simultaneously. In emergency rescue scenarios, by optimizing the construction process and increasing the number of operators, the goal of "on-site entry, on-site erection and on-site traffic on the same day" can be achieved, which effectively solves the industry pain point of tight construction period for temporary bridge erection. The disassembly process is also efficient and convenient. The disassembled components can be classified, packaged and transported without damage, laying a foundation for subsequent reuse, which fully adapts to the application characteristics of "short cycle and high turnover" of temporary projects.

2. High Load-Bearing Redundancy and Stable Mechanical Performance

High load-bearing redundancy and stable mechanical performance provide a solid guarantee for the safe passage of various working conditions, which is another key advantage of Bailey Bridge surpassing other temporary bridges. The Bailey Bridge adopts a triangular truss structure design, which has clear mechanical force transmission paths and excellent bending resistance, shear resistance and lateral displacement resistance.

The rated bearing capacity of a single Bailey panel can reach 270kN. Through the combination of multiple parallel and multi-layer stacking, the bridge bearing level can be flexibly adjusted to adapt to various traffic needs from pedestrians, small passenger cars to heavy engineering machinery and equipment (excavators, muck trucks, cranes) and emergency rescue vehicles, with a maximum bearing capacity of 50-ton heavy loads.

With the support of EVERCROSS BRIDGE TECHNOLOGY's Shanghai R&D center, the components are made of high-quality low-alloy high-strength steel, and undergo double anti-corrosion treatment of shot blasting derusting, galvanizing and painting, which has outstanding corrosion resistance and wear resistance. It can serve stably for a long time under complex outdoor working conditions without frequent maintenance, effectively reducing on-site operation and maintenance costs, and taking into account the dual needs of "temporary use" and "safety and reliability". All products have passed the bearing capacity verification of third-party testing institutions and fully comply with relevant international and domestic standards for safe passage of temporary bridges.

3. Strong Terrain Adaptability and Simple Foundation Treatment

The strong adaptability to the global terrain and no need for complex foundation treatment further enhance the competitiveness of Bailey Bridge as a temporary bridge. Temporary bridge erection scenarios often face problems such as complex terrain, limited site and difficult foundation construction. Bailey Bridge can effectively solve this industry problem with its flexible adaptation characteristics.

Its foundation construction does not require complex foundation pit excavation, steel bar binding and concrete pouring processes. According to the on-site terrain conditions, it can flexibly adopt simple concrete cushion, steel support, natural rock foundation and other foundation forms, which greatly shortens the foundation construction period and reduces the foundation construction cost.

At the same time, the bridge span can be flexibly adjusted through the splicing of Bailey panels, which can accurately adapt to small spans of several meters to the maximum single span of 60 meters. It can also realize the design of different bridge alignments such as straight lines and curves, adapting to various complex scenarios such as river crossing, gully connection, collapse road emergency repair and construction access crossing. Whether it is mountainous areas, waters, muddy areas or extreme environments such as deserts and plateaus, it can be stably implemented, showing extremely strong environmental adaptability. This advantage makes Bailey Bridge widely used in overseas infrastructure projects and "the Belt and Road" related projects, and can well adapt to the complex terrain conditions of various regions.

4. Recyclability and Whole-Life Cycle Economy

The recyclability and whole-life cycle economy are important reasons why Bailey Bridge is favored by engineering enterprises, especially for trade and manufacturing enterprises like EVERCROSS BRIDGE TECHNOLOGY. For engineering enterprises, cost control of temporary projects is the key to improving project profitability, and the recyclable characteristics of Bailey Bridge are one of its core advantages.

All its components have no loss after disassembly, and can be repeatedly assembled and used in different projects and scenarios. The amortization cost of a single use is much lower than that of traditional temporary bridge types, which is especially suitable for trade and manufacturing enterprises, overseas infrastructure projects and units with long-term temporary traffic needs. In addition, the single weight of Bailey Bridge components is reasonably designed (the weight of a conventional Bailey panel is about 270kg), which can be transported long distances by ordinary freight vehicles without large special transport equipment, effectively reducing transportation costs.

On-site operation and maintenance do not require a professional operation and maintenance team. Only regular inspection and fastening of vulnerable parts such as connectors and bearings are needed. When local components are damaged, single components can be quickly replaced without overall maintenance, which further reduces the investment of manpower and material resources for on-site operation and maintenance and realizes the optimization of the whole-life cycle cost.

Application Scenarios and Enterprise Commitment

With the above core advantages, Bailey Bridge has become the preferred product in the field of temporary bridges at home and abroad, and plays an important role in various scenarios such as domestic large-scale infrastructure projects, municipal emergency rescue, flood and earthquake post-disaster reconstruction, and overseas aid construction projects.

As a trade and manufacturing foreign trade enterprise specializing in prefabricated highway steel bridges, EVERCROSS BRIDGE TECHNOLOGY has been committed to promoting the application and development of Bailey Bridge, relying on its professional R&D capabilities and high-quality production level, to provide high-quality and reliable Bailey Bridge products and services for global customers, and help various projects achieve efficient, safe and economical construction.
