The First Successful Application of OVM Prestressed Multi-Directional Displacement Expansion Joint in Malaysia

The First Successful Application of OVM Prestressed Multi-Directional Displacement Expansion Joint in Malaysia

On December 3rd, two sets of prestressed multi-directional displacement expansion joints (OVM-YLF700) for the Muara Lassa Bridge project in Malaysia has successfully installed, this is a mile stone of OVM to promote new type of expansion joints in Malaysia!

The Muara Lassa Bridge project in Malaysia is constructed by the Overseas Company of CCCC Road & Bridge International Co., Ltd, which is part of the local government's plan to upgrade land transport and traffic. The bridge adopts simple support continuous girder structure and the length of the main bridge is 2.43 km. After the completion of the project, it will become the second longest bridge in Sarawak State, which will greatly facilitate the east-west traffic, reduce the transport cost and promote the economic development.

The Muara Lassa Bridge project has specific requirements on the safety and durability of the expansion joints used. In response, OVM's technical team custom-designed a new structure. This new design addressed the risk of accidents caused by non-motorized vehicle tires becoming trapped in the large gaps between the teeth of conventional expansion joints. Additionally, it resolved the issue of bolts at the dead end of conventional expansion joints loosening and breaking due to cyclic loading from vehicular traffic.

Throughout the product ideas design and testing schemes, as well as the testing procedures witnessed by clients during their visits to the rubber products factory, the project staff's meticulous and rigorous work attitude, superior technical expertise, and advanced professional testing equipment garnered consistent praise from clients. During the construction phase, OVM responded to client requirements by dispatching professional engineers to the project site to provide comprehensive training on the installation of the expansion joints to their relevant personnel, guide the installation process, and promptly address any issues that arose, thereby ensuring high-quality installation, which was highly recognized by the client.

OVM prestressed multi-directional displacement expansion joint has outstanding performance of displacement in multiple direction (available in three-way coordinate at longitudinal, horizontal and vertical directions), has passed fatigue test under 2 million cyclic impacts. This is one of OVM flagship products, we believe this joint will be adopted in more and more international projects after the successful in Malaysia.
