Railway concrete protective fence is a kind of barrier facility set up to ensure the safety of railway lines. It consists of the following parts:
Foundation part: The foundation is the supporting structure of the protective fence, which is generally made of concrete. The foundation is usually rectangular in shape, with a length, width and height of 400mm, 200mm and 500mm. Reinforcement should be set inside the foundation to improve its bearing capacity and stability. The function of the foundation part is to fix the entire protective fence to prevent it from being displaced or toppled by external forces.
Column part: The column is the main supporting structure of the protective fence, usually made of steel pipe or H-shaped steel. The height of the column depends on the requirements of the railway line, generally between 3 and 5 meters. The spacing of the columns depends on the design requirements, generally between 3 meters and 5 meters. The function of the column part is to support the entire protective fence and fix it on the ground to prevent it from being toppled or displaced by external forces.
Upper and lower beam sections: The beams are the components that connect the columns, usually made of steel plates or steel pipes. The length of the beam is determined according to the spacing between the columns, which is generally between 1 meter and 2 meters. The function of the beam is to connect the columns into a whole and improve the stability and bearing capacity of the entire protective fence.
Mesh part: The mesh is the main protective part of the fence and is usually made of steel wire. The size of the mesh is determined according to the design requirements, generally between 1 meter and 2 meters. The function of the mesh is to prevent people and animals from entering the railway line and ensure the safety of the railway line.
Column cap and other accessories: Column cap and other accessories include connectors, fasteners, anchors, etc., which are used to connect and fix various components and improve the stability and reliability of the entire protective fence.
In a word, the railway concrete protective fence is composed of several parts such as foundation, columns, beams, mesh and column caps and other accessories. These components work together to ensure the safety of the railway line. In the design and construction process, the characteristics and requirements of each component should be fully considered to ensure that its bearing capacity and stability meet the requirements of relevant standards, and can effectively prevent people and animals from entering the railway line.
