High-Speed Railway Bridge Underpass Protection Fence Application Range: This product is suitable for railway closures on dry bridges with bridge piers of 3 meters in height or more under high-speed railway bridges.

Barbed wire roll cages, metal mesh protection fences, reinforced security fences, and protective barriers under railway bridges collectively constitute the main materials for the protection along high-speed railway lines.

High-Speed Railway Bridge Under Protection Fence, Technical Standards:

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

2; Technical requirements for protective railing 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 made of precast C30 reinforced concrete with a cross-sectional size of 120mm x 120mm and a height of 2.5 meters. Four ø12mm round holes are pre-drilled in the precast poles, which are then secured during installation through bolts to the side connection plates.

5; Metal mesh panels use Q235 rectangular tube frames, size 30mm*50mm, tube thickness 2.0mm; the internal wire mesh is made of HPB300 Φ4.0mm high-strength cold-drawn steel wire, size 75mm*150mm.

6; Connector plate and bolt. The column connection plate and mesh connection plate are made of 90° bent Q235 steel plate with a thickness of 4.0mm, available in two types: A and B, depending on the position of use. Both the connector plate and bolt 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 security fences, reinforced security fences, and under-rail protection fences collectively make up the main materials for the protection along the high-speed railway.

The railway guardrails are made from low-carbon steel wire焊接, mainly divided into two types: galvanized guardrails and coated guardrails. They are assembled by connecting posts with mesh panels.
