[0002] In the modern society's road engineering construction and emergency rescue and disaster relief scene, steel temporary bridge plays a vital role.

[0003] With the rapid economic development and the continuous advancement of urbanization, the demand for road construction and maintenance is increasing. In the process of road construction, it is often necessary to close or reconstruct part of the road, at which time a temporary steel bridge needs to be built to guide vehicles and pedestrians without affecting normal traffic. In addition, after natural disasters such as floods and earthquakes, roads may be damaged, and in order to restore traffic as soon as possible, steel temporary bridges have become an important emergency rescue facility.

[0004] However, the existing steel temporary bridge has many problems in actual application. On the one hand, the installation process of traditional steel temporary bridge is often complex and tedious. Many steel temporary bridges use a connection method that is not convenient enough, requiring a lot of time and manpower to install, which may delay the restoration of traffic in an emergency and affect the development of rescue work. On the other hand, the firmness of the connection needs to be improved. Some steel temporary bridges are prone to looseness and shaking during use due to poor connection, posing a safety hazard to pedestrians and vehicles. Moreover, the existing steel temporary bridge lacks impact cushioning capacity for the road surface when vehicles pass frequently, which can cause damage to the steel temporary bridge and the road surface, shorten its service life, and increase the cost of maintenance and replacement.

[0005] In summary, in order to solve the problems of existing steel temporary bridge such as inconvenient installation, poor connection and insufficient cushioning capacity, there is an urgent need for a new type of assembly type road protection steel temporary bridge to meet the needs of modern road engineering construction and emergency rescue and disaster relief.
