Factory [153*7341*4170] Datong Railway Cement Cable Trench Pre-fabrication (Selected Manufacturer) High-Speed Rail Concrete Subgrade Fencing in Stock!
Pre-fabricated railway line guardrails should be transported to the site for installation, in accordance with the provisions of the "Railway Line Guardrail Management Method."
The smooth terrain is protected with a 2.2m high reinforced concrete fence + barbed wire roll form. This fence offers good stability and is suitable for most areas, but has the drawback of poor climbing ability, with an unsuitable ground slope exceeding 12°. For slopes of 6° or less, the fence unit length is 3.0m, and for slopes between 6° and 12°, the fence unit length is 1.59m.
Steep slopes are equipped with a 2.2m high concrete guardrail in a stepped design, combined with a barbed wire roll cage. For slopes with significant ground undulations and slopes exceeding 12°, where conventional reinforced concrete guardrails are no longer adaptable to the terrain changes, special guardrails are required to mitigate the issue of the lower rail being too high off the ground due to the increased slope gradient.
High-speed rail guardrails on both sides of the entire line are constructed using concrete cement protective fences, metal mesh, and barbed wire rolls. The raw materials for the high-speed rail 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 compared to the traditional expressway and railway guardrails. Additionally, due to the limited contact area of the high-speed rail guardrails, transportation after installation is inconvenient, making them less prone to theft.LostThe high-speed rail barriers are installed using the general line (2012) 8001 drawings, saving costs for secondary maintenance by the railway department in both new and reconstructed railway projects. The construction of high-speed rail barriers is similar to the previously used framed wire mesh, with tightly connected intermediate mesh panels. Our professional installation team at the barrier mesh factory ensures the installation quality, guaranteeing the smooth progress of the project.
1. The concrete durability specifications for high-speed rail guardrails should comply with the "Temporary Provisions for Durability Design of Railway Concrete Structures," with a design lifespan of 30 years for the guardrails; 2. High-speed rail guardrails are produced using a centralized precasting method and installed on-site, enhancing the appearance quality of precast products; 3. Concrete precasting can be done by parts for separate precasting and on-site assembly; 4. During installation of high-speed rail guardrails, metal mesh panels and concrete pillars should be aligned.BetweenAssembled through bolted connections; 5. All pre-buried components and reserved slots, holes for high-speed rail guardrailsLocationDimensions must be accurate to ensure installation precision. 6.
