With the increasing advancement of expressway infrastructure construction today, the inspection well cover plate, as an important component of the road surface system, directly affects the safety, comfort, and durability of road traffic. Traditional metal cover plates have long faced problems such as noise generation, poor corrosion resistance, and insufficient anti-theft performance, while ordinary composite cover plates often struggle to meet the requirements for fatigue resistance under the dynamic loads of high-speed vehicles. The Luzhongbao 500×590×40 Composite High-Speed Cover Plate is developed specifically for high-load traffic environments like expressways, based on advanced composite material technology and dynamic mechanical analysis. Through unique structural reinforcement design, optimized material formulation, and precision manufacturing processes, this product achieves exceptional load-bearing performance, excellent vibration fatigue resistance, and a long service life, providing a reliable solution for expressway inspection facilities.
This product adopts a high-performance composite material system, with dimensions of 500mm × 590mm × 40mm. This rectangular design is optimized through rigorous dynamic simulation, enabling effective dispersion of the dynamic loads generated by passing high-speed vehicles. The 40mm thickness design incorporates a multi-level reinforcement structure, achieving lightweight while ensuring the overall stiffness of the cover plate. The cover plate surface features a deep-tooth anti-slip design, ensuring driving safety in rain and snow while significantly reducing noise when vehicles pass. The product inherits the excellent characteristics of composite materials: corrosion resistance, insulation, and non-magnetic properties. Its innovative structural design achieves a higher level of fit between the cover plate and the well frame, effectively avoiding common issues like bouncing and abnormal noises associated with traditional covers.
