Manufacturer [153*7341*4170] Jinan Railway Concrete Guardrails (Factory Price) Ready Stock Supply for High-Speed Rail Foundation Fencing
The prefabricated railway line protection fences should be transported to the site for installation in accordance with the "Railway Line Protection Fence Management Method."
The flat areas are protected with a 2.2m high reinforced concrete barrier in combination with a barbed wire roll cage. This barrier offers good stability and is suitable for most regions, but it has poor climbing ability, and the ground slope should not exceed 12°. For slopes of 6° or less, the barrier unit length is 3.0m, while for slopes between 6° and 12°, the barrier unit length is 1.59m.
Steep slopes are equipped with a 2.2m high concrete guardrail in step-type design + barbed wire roller form. For areas with significant ground undulations and slopes exceeding 12°, where conventional reinforced concrete guardrails are unable to adapt 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.
High-speed rail guardrails are lined with concrete-cement protective fences, metal mesh, and barbed wire rolls on both sides of the entire line. The raw materials for 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 highway guardrails and railway guardrails. Moreover, due to the limited contact area of the high-speed rail guardrails, transportation after installation is inconvenient, making them less prone to theft.LostReduced the cost for the railway department's secondary maintenance. In both new construction and reconstruction of railway projects, the installation of high-speed rail guardrails uses the Tongxian (2012) 8001 drawings. The construction of high-speed rail guardrails is largely similar to the previously used framework wire mesh, with tightly connected mesh panels. Our factory's professional installation team 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 Design of Durability of Concrete Structures in Railways," with a design lifespan of 30 years for the guardrails. 2. High-speed rail guardrails are produced using a centralized precasting method and an on-site installation scheme, enhancing the appearance quality of the precast products. 3. Concrete components can be precast separately and assembled on-site. 4. During the installation of high-speed rail guardrails, metal mesh panels and concrete pillars should be aligned...BetweenThe components are connected as a whole through bolted joints; 5. All pre-buried parts and reserved slots and holes of the high-speed rail guardrailsLocationDimensions must be accurate to ensure installation precision. 6. High-speed rail guardrail anti-climb spikes and brackets, clamps.ArtificialEnsure a tight fit with no gaps during installation, pull it taut for both aesthetics and practicality.
