The thickened column of Q235 composite pipe bridge guardrail has a long service life. Guanxian Longbang Traffic Facilities Co., Ltd.
The thickened columns of Q235 composite pipe bridge guardrails have a long service life. Guanxian Longbang Traffic Facilities Co., Ltd.'s suspension bridges use steel strand flexible guardrails. The steel wire ropes have a diameter of 19 mm and a breaking tensile force of 250 kN. They pass through the pulleys at the ends of the columns and swing with the bridge deck. The spring bases of the columns can tilt back 25 degrees during impact to absorb kinetic energy and then automatically reset. Adjust the tension once a year to ensure the deviation does not exceed 5%. The self - repairing bridge guardrail adds microbial mineralizers to the concrete. When cracks appear, bacteria metabolize to produce calcium carbonate crystals to fill the cracks. Cracks with a width of less than 0.5 mm can completely heal within 28 days, and the strength after repair can recover to 85% of the original strength. The survival period of the microorganisms in the dormant state can reach 200 years, which meets the 100 - year design life of the bridge. This technology significantly reduces the frequency of crack repair and reduces the whole - life cycle maintenance cost by about 40%. Currently, it is in the pilot stage before large - scale promotion and is expected to become the industry's standard configuration within five years.
The thickened columns of Q235 composite pipe bridge guardrails have a long service life. Guanxian Longbang Traffic Facilities Co., Ltd.'s guardrails in tidal estuaries are made of duplex stainless steel 2205 with a pitting resistance equivalent number (PREN) ≥ 35. The hollow sections of the columns are equipped with drainage holes at the bottom. The PHC pipe piles have a diameter of 400 mm and are driven to a depth of 20 meters. The splash zone is coated with ceramic coatings with a design life of 100 years. The river - side bicycle lane guardrails need to ensure cycling safety, with a height of 1.1 meters. The kick - plates at the bottom are 20 cm high to prevent the wheels from getting stuck. The guardrails adopt an arc - shaped top design to reduce injuries in case of a fall. At the turning points, the guardrails are inclined outward by 5 degrees to reserve more turning space for cyclists. Reflective films are pasted on the surface of the guardrails to improve visibility at night. A mileage marker is set every 50 meters to help cyclists keep track of the distance. These guardrails are designed with reference to the standards of bicycle racing tracks, providing professional - level safety protection for cycling enthusiasts.
The thickened columns of Q235 composite pipe bridge guardrails have a long service life. Guanxian Longbang Traffic Facilities Co., Ltd.'s intelligent charging guardrail columns integrate USB charging ports and wireless charging pads with a power of 15 watts. They have an outdoor waterproof rating of IP65 and can be used by scanning the code for payment, following the sharing - economy model, which solves the problem of outdoor emergency charging. The Japanese dry - landscape garden guardrails are in the form of bamboo fences. They are made of selected Phyllostachys makinoi over three years old, with a diameter of 3 - 5 cm, and are woven after being smoked to prevent insects. The bamboo fences are 1 meter high and are woven in a diamond pattern with a spacing of 2 cm between bamboo strips. The columns are made of Chinese fir logs, which are peeled and coated with tung oil for anti - corrosion. A pebble apron with a width of 30 cm is built at the bottom of the bamboo fence to prevent mud from splashing. These guardrails are simple and natural, complementing the gravel and placed stones in the dry - landscape garden to create a Zen - like space. However, the bamboo has a relatively short service life and needs to be replaced about once every 5 years.
