Introduction to the principle of ECS bridge deck continuous device
1. The internal reinforcement of the ECS bridge deck continuous device and the bridge deck steel mesh are welded to form a space structure, resisting the expansion stress caused by temperature changes and resisting the bending stress generated by the end angle of the beam plate caused by the live load.
2. The reasonably elastic material reduces the bending moment generated by the bending of the beam end, so that the pavement layer concrete and the double-layer steel structure can resist the bending stress and reduce the possibility of crack generation.
3. Even if the concrete in the pavement layer is cracked, the rainwater penetrating into the crack will quickly infiltrate through the permeable layer, and the sides of the bridge will be discharged through the drain pipe. There will be no reflection cracks in the asphalt layer of the bridge deck, and the bridge cover beam will be protected from water. Infringement.
After the bridge deck pavement has cracks in the continuous part of the bridge deck, a reflective crack is formed on the asphalt layer of the bridge deck. After the rainwater seeps into the crack, it cannot be discharged in time, and water accumulates under the asphalt pavement layer, causing more serious damage to the bridge deck and affecting the driving comfort.
Cracks occur on the bridge deck. The cracks in the bridge deck are damaged. The damage not only affects the driving comfort, but also is difficult to repair. It is difficult to re-join the steel bars after repairing, which causes the repair to be damaged in the same year. It is a difficult disease to be cured. Rainwater infiltrates the lower structure along the crack, which accelerates the damage of the bridge structure and affects the structural durability. 13785855258 pay
ECS device product overview
The ECS device is a combination of special high-elasticity materials and steel bars. It is a single-mold molding machine and is a special device for the continuous bridge deck of the simply supported bridge.

The traditional practice of the continuous section of the simply supported beam bridge is to increase the continuous reinforcement of the bridge deck here. Due to the temperature difference effect, the beam plate is stretched and the live load effect causes the beam to flex. Most of the bridge decks are built after one year. Cracks begin to form, causing damage in severe cases, affecting driving comfort. After the part is damaged, it is difficult to repair, and the repaired steel bar is difficult to re-join, which causes the repair to be damaged in the same year, which is a difficult disease to be cured. Due to the secondary excavation during the repair and construction, the road closure caused traffic disruption and vehicle congestion. Secondly, due to the inevitable occurrence of force cracks in the continuous bridge deck, rainwater seeps on the cover beam. According to the investigation, more than 70% of the cover beams of the active support bridges are exposed to such water, and the rainwater seeps into the top surface of the cover beam and mixes with the dust in the air to form mud, which causes the moisture to be stored on the top surface of the cover beam for a long time. The side, and gradually invade the concrete and steel bars, greatly reducing the durability of the cover beam, thus affecting the safety of the entire bridge structure.
