The main uses of modular single seam expansion device are as follows:
1.Bridge engineering
Adapting to bridge deformation: Bridges will experience thermal expansion and contraction due to temperature changes, and the length of the beam body will change accordingly under different seasons and day night temperature differences; When vehicles pass through, the bridge will also undergo vertical and horizontal bending deformation. The modular single joint expansion device can accurately meet the needs of such expansion and deformation, reserve reasonable "expansion space" for bridge structures, prevent cracks and damage to the beam due to limited expansion, and effectively ensure the overall structural safety of the bridge.
Ensuring driving comfort: Its clever design can minimize the impact and vibration caused by passing through expansion joints during vehicle operation. The smooth and even surface of the expansion device ensures a smooth transition of the vehicle, with no noticeable bumps felt by the occupants, enhancing the long-distance driving experience and reducing additional impact loads on the bridge structure.
Extending the service life of bridges: With reliable expansion adaptability and buffering and shock absorption efficiency, the modular single joint expansion device reduces the fatigue damage caused by frequent expansion and impact vibration to the main structure of the bridge, slows down the aging rate of the structure, and thereby extends the service life of the bridge, saving a lot of later maintenance and reconstruction costs.
2.Special sections in road engineering
Elevated roads and overpasses: These types of roads have complex structures, frequent turns and slope changes, complex driving conditions for vehicles, and high impact forces. The modular single seam expansion device can efficiently absorb impacts and adapt to deformations at the joints of various bridge sections, maintain road smoothness, facilitate smooth traffic flow, and prevent traffic congestion and accidents.
Tunnel entrance and exit: The temperature difference between the inside and outside of the tunnel is significant, and the road surface at the entrance and exit is prone to expansion and contraction problems due to the temperature difference. This expansion device can flexibly respond to road expansion and contraction caused by sudden temperature changes, ensuring smooth connection between the tunnel and external roads and eliminating safety hazards.
