The present invention provides a prefabricated assembled
crash barrier for replacing an old bridge and a construction method thereof. The prefabricated assembled
crash barrier comprises a prefabricated concrete
crash barrier body and a steel railing. The concrete crash barrier body is formed with a hoisting hole and a plurality of crash barrier convex strips during production. A prefabricated steel plate and anchor bars are embedded in the top of the concrete crash barrier body, and a reserved protruding
steel bar is embedded in the bottom. The bottom of the steel railing is welded to the top of the prefabricated steel plate. The prefabricated assembled crash barrier of the present invention is prefabricated in a factory and can be
mass-produced, and the quality of the components and the appearance can be well controlled. The hoisting hole is convenient for hoisting and transportation, and the crash barrier convex strips can have a good visual effect. The steel railing is connected to the prefabricated assembled crash barrier as a whole, which further increases the
beautification effect. The prefabricated assembled crash barrier of the present invention has a beautiful appearance, a simple structure, is safe and reliable, is convenient for disassembly and replacement, is convenient for construction, has a short construction period, has little
impact on traffic during the construction process, and has good
economic benefits.
