[0002] In traditional construction processes, when encountering underground pipelines that cannot be relocated and vehicles must cross them, temporary measures are typically taken, such as building temporary bridges or laying temporary roads. However, these methods are not only costly but also have long construction periods, significantly impacting project progress and cost control. Furthermore, temporary facilities have a limited lifespan, and their dismantling generates substantial construction waste, which is detrimental to environmental protection.
