Q235 landscape guardrails are directly supplied by the manufacturer for customized roads. Longbang Traffic Facilities
Q235 landscape guardrails are directly supplied by the manufacturer for road customization by Guanxian Longbang Traffic Facilities Co., Ltd. River channel guardrails are mainly used 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 is not less than 1.2 meters, and the distance from the bottom to the ground does 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. Campus landscape guardrails pay attention to creating a cultural atmosphere. The balustrades are made of enamel steel plates, and school mottos, school emblems or famous quotes are baked on the surface. The thickness of the enamel steel plate is 2 millimeters, which is resistant to acid and alkali corrosion and has a service life of more than 30 years. The text is printed using the silk - screen printing process, with a clarity of 300DPI. The height of the guardrail is 1.1 meters, and the columns are made of H - shaped steel with the surface sprayed in the school's theme color. In front of the library and teaching buildings, the guardrail is partially raised to 1.5 meters to form a cultural wall for displaying students' art works. This kind of guardrail integrates safety education with cultural edification.
Q235 landscape guardrails are directly supplied by the manufacturer for road customization by Guanxian Longbang Traffic Facilities Co., Ltd. For ecological revetment guardrails, the gabion cages are 2×1×0.5 meters and filled with pebbles. The diameter of the steel wire is 3 millimeters and galvanized with Galfan. The porosity is 30%, which is beneficial to the growth of aquatic plants. The top is capped with concrete, and the cost is about 800 yuan per meter with simple maintenance. The design of guardrails on urban viaducts increasingly focuses on the integration of aesthetics and functionality. Aluminum alloy materials have gradually become the choice for landscape bridges due to their characteristics of light weight, high strength, corrosion resistance and easy shaping. Such guardrails usually adopt hollow carvings or streamlined cross - sections, and are equipped with LED light strips to form a night - time light - belt effect, which not only ensures driving safety but also enhances the recognition of the urban skyline. During the design process, engineers need to calculate the coupling effect of wind load and vehicle impact force, and optimize the column spacing and beam cross - section through finite element analysis to control the deformation of the guardrail within 50 centimeters after being impacted by an 80 - ton heavy vehicle. In addition, the guardrail connectors at expansion joints should adopt a sliding structure to avoid stress concentration and damage to the overall stability due to temperature changes.
Q235 landscape guardrails are directly supplied by the manufacturer for road customization by Guanxian Longbang Traffic Facilities Co., Ltd. The anti - collision level S of highway bridge guardrails corresponds to the non - penetration after being impacted by an 80 - ton heavy vehicle at a speed of 65 kilometers per hour. The slope of the F - shaped cross - section is 55 degrees, which allows the tires to climb up the slope and convert kinetic energy. The double - layer and two - way steel mesh has longitudinal bars with a diameter of 16 millimeters and a spacing of 150 millimeters, and the concrete is... Mountain stream and river channel guardrails need to withstand the huge impact force during flash floods, and adopt a gravity - type masonry structure with block stones. The bottom width of the wall is 1.5 meters, the top width is 0.6 meters, and the height is 1.5 meters. The particle size of the block stones is 30 - 50 centimeters, and they are masonry with M10 cement mortar. A settlement joint with a width of 2 centimeters filled with asphalt hemp is set every 2 meters. The top of the wall is poured with C25 reinforced concrete capping with a thickness of 15 centimeters, and cast - iron railing columns are pre - embedded. This kind of guardrail resists the flood thrust by its own weight, with good stability, but it occupies a large area and has a long construction period. At sharp - bend concave banks, the wall foundation is deepened to 1 meter below the scouring line, and large - sized stones are dumped to prevent scouring.
