When traditional bridges collapse in extreme weather, our structure passes the wind resistance test of 200km/hour and the earthquake resistance test of 9 degrees;
This is not a miracle, but a hard-hitting answer to the company's 20 years of technological accumulation.”Corrosion-resistant steel technology: adopts the patented "nano aluminum infiltration + micro arc oxidation" composite coating (attached material inspection report), corrosion resistance life of 50 years (industry average 15 years), the corrosion rate of a certain coastal project measured 0.003 mm / year.
the first "cellular sandwich steel plate" reduces weight by 40% under the same load, and saves 820 tons of steel in the case of bridges across the river.
Structural design
Topology optimization algorithm: "Dynamic load adaptive structure system" based on ANSYS Workbench development, realizing stress distribution uniformity improvement of 65%.
Modular connection: "magnetic fast installation node," 8 workers complete 80-meter bridge assembly in 3 hours (traditional process takes 7 days).
Manufacturing process
Laser intelligent welding: German KUKA robot + self-developed welding path algorithm, 99.97% qualified weld rate (industry average 92%), high-speed rail project won the "Lu Ban Award".
3D printing reinforcement: metal powder bed melting technology printing bridge supports, compressive strength up to 1200MPa, mine bridge case reduces on-site welding amount by 70%.
Multi-source data fusion: integrates 12 types of sensors, including strain, vibration, temperature, humidity, displacement, etc., with data acquisition frequency up to 100 Hz (industry average 10 Hz).
Digital twin platform: 1:1 virtual bridge real-time mapping, fault warning 72 hours in advance.
Extreme environment testing
Typhoon test: At the Zhejiang Zhoushan Typhoon Test Field, it successfully resisted the combined load of a 17-level typhoon (wind speed of 48m/s) + 12m wave height.
Freeze-thaw test: 300 cycles of -40°C to 80°C without cracking of welds (compared with traditional bridge data on freeze-thaw deformation).
