2012 "Railway Line Protection Fence" [General Reference Drawing (2012) 8001]!

Atlas specifications: The railway fence is no longer made of the traditional welded wire mesh fence, razor wire fence, and other products, but instead features a defensive, long-lasting design: Reinforced concrete fence + 0.5-meter-high razor wire roll cage protection fence. Detailed content as follows:

(1) The barbed wire cage is formed by wrapping the blade wire around a spool, with adjacent loops connected by barbed wire connectors at 120° intervals. When opened, it forms a snake-like mesh. Closed, the diameter of the blade wire loops is 50cm, and the spacing between each intersecting loop when opened is 20cm, with a diameter of no less than 45cm.

(2) Blade barbed wire is formed by mechanically pressing and rolling punched steel plates onto steel wires. The blade width is 22mm, the vertical distance between the two blades is 15mm, the longitudinal distance between the blades is 34mm, and the core wire diameter is 2.5mm. The blades are cut from Q195 steel plates with a thickness of 0.5mm, and the core wire is processed from HPB300 ø6.5mm high-strength steel wire.

(3) The barbed wire roll cage is connected to the vertical reinforcing bars fixed on the bracket by barbed wire clips. The connection between the vertical reinforcing bars and the bracket is secured using ø2.5mm cold-drawn galvanized steel wire, twisted around twice and tightened. The brackets are set at the columns and mid-span of the 3m span protective fence, with additional spans only at the upper part of the columns. The brackets and protective fence are connected using bracket clamps.

(4) The lower edge of the barbed wire roller cage is 0.05m vertically away from the top edge of the reinforced concrete protective fence.

Pre-fabricated railway line protection fences should be transported to the site for installation in accordance with the "Railway Line Protection Fence Management Method."

The flat areas are protected with a 2.2m high reinforced concrete fence plus a barbed wire roll. This fence offers good stability and is suitable for most regions, but has the drawback of poor climbing ability, with an unsuitable gradient exceeding 12°. For gradients of 6° or less, the fence unit length is 3.0m, while for gradients between 6° and 12°, the fence unit length is 1.59m.

Steep slopes are equipped with a stepped 2.2m high concrete protective fence in combination with a barbed wire roll cage. For slopes with significant ground undulations and slopes exceeding 12°, where conventional reinforced concrete protective fences cannot adapt to the terrain changes, special protective fences are required to mitigate the issue of the lower sill being too high off the ground due to the increased slope.

8001 Rail Line Protective Fence

Setting for sparsely populated areas: When railways pass through mountainous areas, deserts, etc., where there is no human or animal traffic year-round, the cost of setting reinforced concrete protective fences is high, and the utilization rate is low. In line with the principle of economic rationality, it can be considered to set up 1.8m high reinforced concrete pillars with metal mesh protective fences in these areas.

Population-dense areas and special location arrangements

For special locations near villages and towns, densely populated areas, both ends of stations, and both sides of elevated interchanges, a 2.2-meter-high reinforced concrete protective fence with barbed wire rolls can be considered. Alternatively, individual structural designs can be adopted for the fence, with enhanced strength, and a height of no less than 2.7 meters.
