Composite pipe bridge guardrails with optional materials, suitable for urban expressways with impact resistance, Longbang Traffic Facilities
The material of the bridge guardrail can be selected as composite pipe. It is used for urban expressways and has impact resistance. The bridge guardrails of Guanxian Longbang Traffic Facilities Co., Ltd. need to balance anti-collision and clear sightlines. The corrugated beam steel guardrail buffers the impact of vehicles through energy-absorbing deformation. The hot-dip galvanizing treatment can withstand the weather for more than 20 years. The height of the median guardrail is not less than 110 cm. The roadside guardrails are configured differently according to traffic flow to ensure the structural integrity under extreme conditions. The light-interactive bridge guardrail realizes the interactive effect with pedestrians and vehicles through the programmed LED light array. The sensors capture the positions of pedestrians, and the lights flow accordingly to form a following halo; when vehicles pass by, the lights change colors to simulate the wake. The pixel spacing of the LEDs is 10 cm, the brightness of a single LED is 200 lumens, and the color temperature is adjustable from 3000K to 6500K. The control system uses the DMX512 protocol, and the response delay is less than 50 milliseconds. This kind of guardrail turns the bridge into a large-scale public art piece, which has extremely high ornamental value at night and has become a highlight project of the urban night tour economy.
The self-healing guardrails of Guanxian Longbang Traffic Facilities Co., Ltd., whose material of the bridge guardrail can be selected as composite pipe and is used for urban expressways with impact resistance, have microbial mineralizers added to the concrete. Cracks within 0.5 mm can be completely healed in 28 days. The bacteria can remain dormant for 200 years, suitable for a century-long design. After repair, the strength can recover 85%, and the maintenance cost can be reduced by 40%. The anti-ship-collision guardrails for river channels are set on both sides of the bridges in navigable waterways. Floating steel anti-collision boxes are used, filled with closed-cell foam inside, with sufficient buoyancy. The size of the anti-collision box is 3×1.5×1 meters, the thickness of the outer shell steel plate is 6 mm, and the surface is painted with red and white warning paint. The box is connected to the riverbed anchor by a chain and can rise and fall with the water level. When a ship deviates from the channel and hits the anti-collision box, the box deforms to absorb energy and protect the safety of the bridge pier. The cost of each anti-collision box is about 50,000 yuan, but it is negligible compared to the bridge repair cost. Three sets are installed upstream and downstream of important bridges respectively to form a protection array.
The balcony guardrails of Guanxian Longbang Traffic Facilities Co., Ltd., whose material of the bridge guardrail can be selected as composite pipe and is used for urban expressways with impact resistance, have an aluminum alloy frame sandwiching tempered glass. The wall thickness is 1.5 mm and the height is 1.1 meters. The glass is 6+0.76+6 mm laminated safety glass. The spacing between the columns is 1.2 meters. The surface is powder-coated in white or grey, which is commonly used in modern households. The anti-terrorist bridge guardrails are designed for the risk of attacks. Anti-explosion steel cables are installed inside the guardrail columns. When the system detects that a vehicle is accelerating abnormally and hitting, the steel cables will be instantly tightened to form a barrier net. The diameter of the steel cable is 12 mm, the breaking tension is 180 kN, and the tightening time is 0.2 seconds. The sensors use dual-mode detection of radar and infrared, with a false alarm rate of less than one in a million. The control system is independently powered, and the backup power supply can continue to work for 72 hours after a power outage. This kind of guardrail has been applied on bridges near important government agencies, greatly improving the safety protection level of key areas.
