Factory Model 【153*7341*4170】Shijiazhuang Railway Cement Protective Fence (In Stock & Immediate Shipment) High-Speed Rail Concrete Pre-cast Barrier Manufacturer
2.5m high-speed rail concrete pillars and concrete guardrails are constructed according to the general reference drawing of "Railway Line Guardrails" (Tongxian (2012) 8001) issued by the Economic Planning Research Institute of the Ministry of Railways in April 2012. For general sections, 1.8m high guardrails are used, while for key sections, 1.8m high reinforced concrete guardrails + 0.5m high barbed wire rolls are employed. The guardrails are set 0.5m within the land boundary. Key areas for the 2.5m high-speed rail concrete pillars and concrete guardrails include: 1) Sections where the railway passes through densely populated areas with 8,584 residents. 2) The entire station area is equipped with 1.8m high reinforced concrete guardrails + 0.5m high barbed wire rolls.
Not all high-speed trains are equipped with guardrails. The guardrails along the entire line use concrete-cement protective fences, metal mesh, and barbed wire roll materials. The raw materials for the high-speed train guardrails are all made of national standard angle steel, steel pipes, and low-carbon steel wire, which are more aesthetically pleasing and offer stronger protective and deterrent functions compared to the traditional highway and railway guardrails.

The raw materials for the high-speed train guardrails are all made of national standard angle steel, steel pipes, and low-carbon steel wire, which are more aesthetically pleasing and have stronger protective and deterrent functions than the traditional highway and railway guardrails. Moreover, due to the limited contact area of the high-speed train guardrails, they are not easy to be stolen or lost after installation, thus saving the maintenance costs for the railway department. The installation of high-speed train guardrails in new and reconstructed railway projects follows the General Line (2012) 8001 drawings. The construction of high-speed train guardrails is similar to the previously used frame-type wire mesh, with tightly connected mesh panels. Our professional installation team at the guardrail factory can ensure the installation quality and the smooth progress of the project.1. The concrete durability specifications for high-speed rail guardrails should comply with the "Provisional Regulations for Durability Design of Railway Concrete Structures," with a design service life of 30 years for the guardrails; 2. High-speed rail guardrails are prefabricated centrally and installed on-site, enhancing the appearance quality of prefabricated products; 3. Concrete prefabrication can be done by parts, followed by on-site assembly; 4. During installation, metal mesh panels are connected to concrete pillars through bolted connectors to form an integrated unit; 5. The positions and dimensions of all embedded components and reserved slots and holes in high-speed rail guardrails must be accurate to ensure installation precision; 6. When installing the anti-climbing spikes and brackets of high-speed rail guardrails, ensure tightness and no gaps, and tighten them to ensure both aesthetics and practicality.
