Transportation buildings are primarily categorized into bridges, ferries, tunnels, airports, train stations, docks, and highways. Bridges are transportation structures connecting two shores, primarily used for crossing rivers, spanning valleys, and straits; ferries are waterways beneath bridges, typically connecting rivers, lakes, and oceans; tunnels penetrate mountains and land, connecting more places at a faster speed. Airports serve as takeoff and landing points for civilian aircraft; train stations provide convenience for passengers to reach their destinations; docks are primarily used for water transportation; and highways offer a swift means of travel for people.
       Experimental equipment is widely used in the field of construction, primarily in the following aspects:
       1. Gravelometer: This equipment is primarily used to test the impact resistance of materials such as concrete, steel bars, tiles, etc., to ensure their safety performance under natural disasters and other external impacts. It can also be used in the automotive industry and aerospace field to evaluate the impact resistance of materials in these environments.
       2. Construction industry testing machine: This equipment is primarily used to test the performance of various construction materials, including structural materials and decorative materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks and tiles, ceramics, glass engineering plastics, composite materials, etc.; decorative materials include various coatings, paints, coatings, veneers, colored tiles, glass with special effects, etc.
       In addition, the application of experimental equipment in the construction field also includes non-destructive testing instruments, such as ultrasonic detectors and radiographic detectors, which are used to detect internal defects and performance indicators of building materials to ensure the quality and safety of buildings.
