Ecological construction method by the deployable bridge

Global warming is a result of greenhouse gas emission from various sources, such as industrial manufacturing, transportation, and construction activities. Among these, construction activities further involve the destruction of the natural environment, which should be protected for ecological balance. During construction, the natural environment should be protected by preserving the natural scenery while ensuring safe and rapid construction. To achieve this, the construction structure needs to be designed with the features of light weight, high efficiency, and safety using deployable structures. Deployable structures are superior over general structures because they can be extended in any area within a few hours and have less impact on the natural environment of the construction site, thus providing an alternative choice for environmental protection and conservation. In a deployable structure model, deployment and truss structures are combined using the scissor mechanism concept. However, the structure is required to remain in a stationary condition. Therefore, this study investigates the equilibrium theory of the scissor structure and presents the methodology of a new bridge construction method.
