Technical Requirements for High-Speed Railway Bridge Underpass Protection Fence
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, with a cross-sectional size of 120mm x 120mm and a height of 2.5m. Four 12mm diameter round holes are pre-drilled during prefabrication, which are secured during installation through bolts to the side connection plates.
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 steel wire, size 75mm*150mm.
6; Connection 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 position. Both the connection plates and bolts are made of Q235 steel and are zinc-plated, 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 roll cages, metal mesh protection fences, reinforced security fences, and protective fences under railway bridges collectively constitute the main materials for the protection along high-speed railway lines.
The railway protection fences are made of low-carbon steel wire焊接, mainly divided into two types: galvanized protection fences and plastic-coated protection fences, which are assembled by connecting posts with mesh panels.
