Bridge anti-seismic solutions

OVM leads the industry in bridge seismic isolation technology, focusing on providingcomprehensive solutions for bridge engineering from design to construction with onestop services. This includes efficient bearing systems, advanced expansion devices,and high-performance dampers. By integrating innovative engineering technology andexcellent manufacturing processes, we ensure structural safety and durability.

Features

· Seismicisolation technology.Reduce structural responsethrough increasing structural damping, extending thenatural vibration period of structure,isolating seismicenergy to achieve excellent anti-seismic effect;
· Adopting seismicisolation technology.Compared withtraditionalanti-seismic structures, the acceleration ofisolated structures is only equivalent to 1/4~ 1/12 of theacceleration of traditional structures, greatly improvingsafety and reliability;
· It has good durability, resistance to low cycle fatigue, hot airaging, ozone aging, acid resistance, waterresistance, and alifespan of over 60 years,
· According to customer needs, monitoring systems and fireprevention technology can be provided

Shenzhen-Zhongshan Connection Line (2020) - Applied anchorage and pendulum bearing with different performance in each direction.

Indonesia JAPEK Project (2018)
The project is located in the earthquake zone of Indonesia, and the entire elevated bridge uses a seismic isolation system. It is the largest overseas anti-seismic bearing project of OVM Company. And the bearing of this project has completed the type-test following European standard series in the Italian laboratory.

Tian'e Longtan Bridge (2024) 
- with a main span of 600 meters, the world's largest span rigid frame concrete arch bridge, applied intelligent height-adjustable bearing.

Bogota Metro Line 1, Colombia, 2024
OVM’s largest bearing project in the South American market, in which has successfully applied anti-seismic and anti-lifting bearings to the rail transit field under the American standard.
