Prefabricated 3D Positioning Intelligent Vibration-Reducing and Noise-Controlling Expansion Joint Device
Description
The prefabricated, three-dimensional, intelligent vibration- and noise-reducing expansion joint is a transformative, iterative upgrade based on the conventional modular expansion joint. While retaining the unique performance characteristics of the 3D intelligent vibration- and noise-reducing expansion joint, this innovative product further advances the development of prefabrication, multi-functionality, and smart technology for expansion joints. As a result, it significantly enhances the flexibility for maintenance and upkeep, extends the service life of the joint, and ultimately reduces the overall cost of bridge construction.
Performance Features
◆ The expansion joint body and its connecting components form the entire pre-fabricated, modular steel-structure expansion segment beam. By eliminating concrete usage, this approach ensures superior fabrication quality and precision, truly enabling factory-based, fully prefabricated, modular, and intelligent construction of expansion joints—facilitating convenient maintenance, upkeep, and replacement of the expansion devices in the future.
◆ Reduced on-site construction workload, shortened the construction timeline, eliminated numerous uncontrollable safety risks associated with field operations, ensured the structural integrity of the bridge, minimized waste of construction materials, and cut down on labor, tools, vehicles, and equipment investments—thereby significantly lowering both construction and maintenance costs.
◆ The application of fully prefabricated, modular steel expansion joint segments enables rapid, lane-by-lane replacement construction and localized maintenance. This approach eliminates many of the unpredictable safety risks associated with conventional methods, safeguards the integrity of the bridge’s main structure and protects the surrounding environment. It also significantly reduces the duration of traffic control during seam replacement, ensuring smooth and uninterrupted traffic flow while minimizing social impact and avoiding disruptions to normal toll operations.
◆ Construction is convenient and less affected by natural conditions. In contrast, traditional cast-in-place construction faces significant challenges in concrete curing during adverse weather conditions such as heavy rain or strong winds, leading to delays in work schedules, idle time on-site, and ultimately higher labor costs, as well as wasted resources like equipment and vehicles.
◆ More carbon-friendly and environmentally friendly. Replacing this expansion device doesn’t require chiseling away the concrete in the anchorage zone, thus avoiding any damage to the bridge. Additionally, the original expansion device itself can be recycled and reused, promoting sustainable development while reducing costs and boosting efficiency.
