To me, these types of videos provide zero information, just like a movie scene. Plz in this type of video provides the name of the country where it was made and the time to complete this project.
The technological aspects of the building affect the modern bridge industry from the first steps of design. All bridge families, such as initiated bridges, span bridges and balanced cantilever bridges, take their name from the method of construction. The full span method, which is very often used in high speed rail projects, is another example.
The bridge industry is moving towards mechanized construction because it saves labor, shortens project time and improves quality. This trend is evident in many countries and includes most construction methods. Mechanized bridge construction is based on the use of special mounting equipment.
Beam ramps are used for erecting precast beams. Self-opening portals and lifting frames are used to construct precast segmental bridges. Movable scaffolding systems (MSS) and formwork fasteners are used for on-site casting of openings and segments of prestressed concrete bridges. Forming carts are used for segmental casting of composite bridges from concrete slab. Gantry carriers with bottom bridges and aperture launchers fed by tire trolleys are used for carrying and placing the pre-cast openings. Lifting platforms are used to lift macro segments for suspension bridges. Alternative machine configurations are also available for most construction methods.
Next generation bridge construction equipment is complex and precise. Handles heavy loads on long spans under the same restrictions that the overpass obstruction imposes on the bridge. The safety of operations and the quality of the final product depend on the complex interactions between human decisions, structural, mechanical and electro-hydraulic components, control systems and the bridge being built.
