High-Speed Rail Bridge Underpass Protective Fence Application Range: This product is suitable for railway enclosures on dry bridges with bridge piers of 3 meters in height or more for high-speed rail bridges.
Barbed wire roll cages, metal mesh protective fences, reinforced security fences, and protective 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 Engineering Construction (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.
Column is made of C30 reinforced concrete precast, with a cross-sectional size of 120mm*120mm and a height of 2.5m. Four 12mm diameter round holes are pre-drilled during precasting, which are secured with bolts to the connecting plates during installation.
5; Metal mesh panel with Q235 square tube frame, size 30mm*50mm, square tube thickness 2.0mm; internal wire mesh made of HPB300 φ4.0mm high-strength cold-drawn wire, size 75mm*150mm.
6; Connection plate and bolt. The column connection plate and mesh connection plate are made of 90° bend Q235 steel plate with a thickness of 4.0mm, available in two types, A and B, depending on the installation location. Both the connection plates and bolts are made of Q235 steel and are galvanized with a zinc coating 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 reels, metal mesh security fences, reinforced security fences, and under-rail protection fences collectively constitute the main materials for the protection along the high-speed railway.
Railway guardrails are made from high-quality low-carbon steel wire焊接, primarily divided into two types: galvanized guardrails and coated guardrails. They are constructed by connecting upright posts with mesh panels.
