Description

Technical Field

[0001] This utility model relates to the field of cantilever slabs, specifically a prefabricated cantilever slab for road widening. Background Technology

[0002] In recent years, the country has strongly advocated the construction of eco-friendly and sustainable green highways. Therefore, researching ecological widening methods and exploring ecological design techniques for building ecological roads has significant engineering implications. For riverside roads in mountainous areas with complex terrain requiring widening by up to 2 meters, widening by filling the roadbed would significantly impact river flood control. Using cantilever slab structures can effectively solve the flood control problem, minimizing environmental impact. Precast cantilever slab structures are easy to manufacture, effectively shorten the construction period, and have a simple construction process. Compared to roadbed widening, they save on materials and project costs, making them a better eco-friendly widening method. However, existing cantilever slabs are not convenient for adjusting their height according to usage needs, leading to installation inconvenience.
