Manufacturer [153*7341*4170] Shijiazhuang Railway Cement Protection Fence Manufacturer (In Stock Supply) High-Speed Railway Concrete Subgrade Guardrail Quotation

High-Speed Railway Bridge Underpass Protection Fence Application Range: This product is suitable for railway closures on dry bridges with pier heights of 3 meters and above on high-speed railway bridges.

Barbed wire reels, metal mesh protection fences, reinforced security fences, and protection fences under railway bridges collectively form the main materials for the protection along high-speed railway lines.

High-Speed Railway Bridge Underpass Protection Fence; Technical Standards:

General Reference Drawing for Railway Construction Engineering (Underpass Protection Fence, Main Line (2012) 8002).

2; Technical requirements for the protective fence under high-speed railway bridges:

3; Reinforced concrete pillar metal mesh fence consists of pillars, mesh panels, and connecting parts, with a protective height of 1.8 meters.

4; Poles are prefabricated with C30 reinforced concrete, featuring a cross-sectional size of 120mm x 120mm and a height of 2.5 meters. Four ø12mm circular holes are pre-drilled during the prefabrication process. During installation, the poles are secured to both side connection plates using bolts.

5; Metal mesh panels are framed with Q235 rectangular tubes, 30mm x 50mm in size, with tube thickness of 2.0mm; the internal wires are made of HPB300 φ4.0mm high-strength cold drawn steel wire, 75mm x 150mm in size.

6; Connector plates and bolts. The column connection plates and mesh connection plates are made of 90° bent Q235 steel plates with a thickness of 4.0mm, available in two types, A and B, depending on the usage location. Both the connector plates and bolts are made of Q235 steel and are galvanized, with a galvanizing amount of 270g/m².

Precision requirements for the connector plate: Length tolerance ≤ 1.0mm, width tolerance ≤ 0.5mm, thickness tolerance ≤ 0.5mm, hole position deviation ≤ 1.0mm.

Barbed wire rolls, metal mesh protective fences, reinforced protective fences, and under-rail protective fences collectively form the main materials for the protection along the high-speed railway.

Railway protection fences are made from high-quality low-carbon steel wire焊接, primarily divided into two types: galvanized protection fences and plastic-coated protection fences, which are assembled by connecting posts with mesh panels.
