Non-standard landscape guardrails. Quality guaranteed by the source factory with high impact resistance. Longbang Traffic Facilities
Non-standard landscape guardrails, guaranteed quality from the source factory with high impact resistance. Guanxian Longbang Traffic Facilities' intelligent bridge guardrails are integrated with fiber Bragg grating strain gauges with an accuracy of ±1 microstrain, and acceleration sensors to identify the impact position. When the temperature and humidity monitoring exceeds 80% continuously for 24 hours, an early warning will be triggered. The data is transmitted to the cloud via 4G, and it is powered by solar energy with a 7-day battery life without sunlight. The anti-collision level of highway bridge guardrails needs to reach S (160 kJ of collision energy), which means that an 80-ton heavy vehicle hitting at a speed of 65 km/h will not penetrate. The concrete guardrail uses an F-shaped cross-section with an inclined plane angle of 55 degrees, which can make the vehicle tires climb up the inclined plane and convert kinetic energy into potential energy, reducing the harm to passengers. The steel bar configuration uses double-layer and two-way mesh sheets. The longitudinal bars have a diameter of 16 mm and a spacing of 150 mm, and the stirrups have a diameter of 12 mm and a spacing of 200 mm. The concrete strength grade is 0. The guardrail root is connected to the bridge deck flange through shear keys, and the shear bearing capacity is greater than 800 kN. At the expansion joints, the gap between the guardrails is no more than 5 mm, and guide grooves are set on both sides to guide the smooth transition of vehicles.
Non-standard landscape guardrails, guaranteed quality from the source factory with high impact resistance. For the guardrails in the river fishing area of Guanxian Longbang Traffic Facilities, stainless steel fishing rod brackets are added, which can be rotated and adjusted. The anti-corrosion wooden seats are 40 cm wide with backrests. The guardrail is lowered to 0.9 meters, and each fishing position is separated by a partition every 2 meters. There are fish guard hooks and bucket racks below. The guardrails of landscape arch bridges are often designed in an arc shape that echoes the lines of the arch ring. The forged iron guardrails form decorative patterns such as vines and waves through manual bending, combining classical charm with the beauty of modern craftsmanship. The structural stress of this type of guardrail needs to specially consider the influence of horizontal thrust on the arch springing. Therefore, a reinforced column is set every 6 meters, and its cross-sectional size is 50% larger than that of ordinary columns. The surface treatment uses hot-dip galvanizing and electrostatic spraying processes. The primer is zinc-rich paint, and the topcoat is acrylic polyurethane. The color can be customized according to the theme of the bridge, such as bronze, antique bronze or white. At the top of the arch, the height of the guardrail is appropriately reduced to 1.2 meters to ensure the viewing vision, but the safety of anti-falling is compensated by increasing the density of the railings to 10 per meter.
Non-standard landscape guardrails, guaranteed quality from the source factory with high impact resistance. The panels of the river science popularization guardrails of Guanxian Longbang Traffic Facilities are UV-printed with river ecological knowledge, including fish species, aquatic plants, and water quality principles. The QR code on the back links to science popularization content, and it is weather-resistant for more than 5 years. Schools can organize on-site teaching. The rural river guardrails pursue economy and practicality, using a combination of precast reinforced concrete columns and wire mesh sheets. The column has a cross-section of 12×12 cm and a height of 1.5 meters, with 4 steel bars of 12 mm in diameter inside and a spacing of 2 meters. The wire mesh sheet has a pore size of 5×5 cm, a wire diameter of 3 mm, and a height of 1.2 meters. The columns and mesh sheets are connected by hooks, which is easy to install. The foundation uses C20 concrete with a size of 40×40×50 cm. The cost per meter is about 200 yuan, which is one-tenth of the price of urban guardrails. Although it lacks aesthetics, it is strong and durable, and is very suitable for promotion in rural areas.
