Galvanized landscape bridge guardrails are available in a complete range of specifications and with excellent craftsmanship. Longbang Traffic Facilities
Galvanized landscape bridge guardrails are available in a complete range of specifications and with excellent craftsmanship. Longbang Traffic Facilities The detachable standard section of the river dredging access road guardrail is 3 meters long and connected by bolts. It is fixed with flange plates and anchor bolts. The height is 1 meter, and there is a 30 - centimeter gap at the bottom. The Q235B steel is hot - galvanized. It can be temporarily removed during dredging and restored after completion. The anti - terrorist bridge guardrail is designed for attack risks. An explosion - proof steel cable is installed inside the guardrail column. When an abnormal acceleration impact of a vehicle is detected, the steel cable is instantly tightened to form a blocking net. The diameter of the steel cable is 12 millimeters, the breaking tensile force is 180 kN, and the tightening time is 0.2 seconds. The sensor uses radar and infrared dual - mode detection, and the false alarm rate is 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.
Galvanized landscape bridge guardrails are available in a complete range of specifications and with excellent craftsmanship. Longbang Traffic Facilities The river water level marking guardrail has scales engraved on the side of the column every 10 centimeters. The range from the water level to the embankment top is printed with luminous paint. The electronic water level gauge uploads data in real - time. When the water level exceeds the warning line, the LED red light flashes and the broadcast automatically reports. The Japanese dry landscape guardrail adopts the form of bamboo fence. Well - selected Phyllostachys makinoi over three years old with a diameter of 3 - 5 centimeters is used. After being smoked to prevent insects, it is woven. The height of the bamboo fence is 1 meter, and the diamond weaving method is adopted with a 2 - centimeter spacing between bamboo chips. The columns are Chinese fir logs. After peeling, they are painted with tung oil for anti - corrosion. A pebble apron with a width of 30 centimeters is built at the bottom of the bamboo fence to prevent mud from splashing. This kind of guardrail is simple and natural, matching well with the gravel and placed stones in the dry landscape, creating a Zen - like space. However, the service life of bamboo is relatively short, and it needs to be replaced every about 5 years.
Galvanized landscape bridge guardrails are available in a complete range of specifications and with excellent craftsmanship. Longbang Traffic Facilities The sound - absorbing guardrail is filled with rock wool inside the metal plate, and the noise reduction coefficient NRC reaches 0.8. With a height of 2.5 meters, it can effectively block traffic noise. The surface has micro - perforations for sound absorption. The spacing between H - shaped steel columns is 2 meters, and it is widely used on both sides of the road. The prefabricated bridge guardrail adopts the construction mode of pre - fabrication in the factory and on - site hoisting. Each single component is 4 - 6 meters long and weighs 3 - 5 tons. The components are connected by grouting sleeves. The strength grade of the grouting material is C80, and the 28 - day compressive strength is not less than 80 MPa. There are shear grooves on the back of the guardrail to form an integral whole with the cast - in - place layer of the bridge deck. The groove depth is 20 millimeters, and the spacing is 400 millimeters. The pre - fabrication accuracy requires the length error of the component to be ±3 millimeters, the height error to be ±2 millimeters, and the diagonal difference to be ≤5 millimeters. A three - way jack is used for leveling during installation, and the verticality deviation is controlled within H/1000. Compared with cast - in - place construction, this construction method can shorten the construction period by 60% and reduce on - site wet work by 90%, which is especially suitable for winter construction.
