Q235 Landscape Overpass Guardrails, Beautiful and Protective for Urban Expressways, Longbang Traffic Facilities
Q235 Landscape Overpass Guardrails, Beautiful and Protective for Urban Expressways, Longbang Traffic Facilities River channel guardrails are primarily designed to prevent people from falling into the water and at the same time meet the requirements of flood discharge. The net height on the riverside side should not be less than 1.2 meters, and the distance from the bottom to the ground should not exceed 15 centimeters. The spacing between vertical bars is 11 centimeters, and the spacing between horizontal bars is 20 centimeters. When the flow velocity exceeds 2 meters per second, the foundation should be deepened to 1 meter below the riverbed. Garden landscape guardrails pursue harmonious coexistence with the natural environment and often adopt the form of a dry - stacked rubble low wall, with a height of 40 - 60 centimeters, which has the functions of defining space and providing seating. Local river pebbles or mountain stones are selected as the rubble, with a well - arranged combination of different sizes. The gaps are filled with gravel or planted with drought - resistant plants such as moss and sedum. An anti - corrosion wooden board with a width of 30 centimeters is laid on the top of the wall to form a natural seat. This kind of guardrail is low - cost, eco - friendly, and in line with the artistic conception of mountain and water gardens, so it is widely used in parks and green spaces.
Q235 Landscape Overpass Guardrails, Beautiful and Protective for Urban Expressways, Longbang Traffic Facilities Self - repairing guardrails: Microbial mineralizers are added to the concrete. Cracks within 0.5 millimeters can be completely healed within 28 days. The bacteria have a dormancy period of 200 years, suitable for a 100 - year design. After repair, the strength can be restored to 85%, and the maintenance cost can be reduced by 40%. Rural river channel guardrails pursue economy and practicality, using a combination of pre - cast reinforced concrete columns and wire mesh. The cross - section of the column is 12×12 centimeters, with a height of 1.5 meters, and it is equipped with 4 steel bars with a diameter of 12 millimeters inside, with a spacing of 2 meters. The aperture of the wire mesh is 5×5 centimeters, the wire diameter is 3 millimeters, and the height of the mesh is 1.2 meters. The columns and the mesh are connected by hooks, which is easy to install. The foundation uses C20 concrete, with a size of 40×40×50 centimeters. The cost per meter is about 200 yuan, which is one - tenth of the price of urban guardrails. Although it is not very aesthetically pleasing, it is strong and durable, and is very suitable for popularization in rural areas.
Q235 Landscape Overpass Guardrails, Beautiful and Protective for Urban Expressways, Longbang Traffic Facilities The folding angle of the zig - zag guardrail is 150 - 170 degrees, and the radius at the turning point should not be less than 300 millimeters. Each section is 3 - 6 meters long, continuously welded and then cut into sections. The color of the fluorocarbon spray changes with the light. The torque effect needs to be considered in the anti - collision calculation, and the cross - section of the columns should be strengthened. European classical landscape guardrails are represented by wrought - iron art, with patterns such as scrollwork and rose branches forged by hand. Each one is a work of art. The wrought - iron components are made of Q235 low - carbon steel, heated to 1000 degrees Celsius and then forged by hand, and then quenched and tempered to improve toughness. The surface treatment is hot - dip galvanizing plus multi - layer paint. The primer is zinc - rich, the intermediate paint is micaceous iron oxide, and the topcoat is alkyd enamel, with a total thickness of 200 microns. The height of the guardrail is 1.3 meters, and the top of the columns is decorated with a crown or flame shape. This kind of guardrail shows noble qualities and is commonly seen in high - end villa areas and manors.
