ECS deck continuous installation background information
The water damage of the cover beams and platform caps of existing simply-supported structural bridges is very common. After investigation, 70% of cover beam and platform caps have such diseases. In the design of cover beams, most of them are reinforced concrete structures. Forced cracks are inevitable under load. Although we restrict the width of cracks through reinforcement, some cover beams are due to construction quality and overload phenomena. Crack widths often exceed the specification limits. The existence of cracks in the cover beam coupled with water damage poses a great danger to the durability of the cover beam.
The simply-supported bridge adopts the bridge continuous structure. In the traditional continuous bridge deck construction, continuous reinforcing steel is added to the bridge deck, and the reinforced concrete mesh is then cut off so that the reinforcement steel meshes on the front and rear bridge decks cannot be continuous. 137-8585-5258 pay
Due to the effect of temperature difference, the beam plate flexes due to telescopic and live-load effects, and the concrete thickness at the continuous surface of the bridge is generally 8 to 10 cm. The internal single-layer steel and weak concrete are not sufficient to resist bending stress. Most of the continuous surfaces of the bridge are One year after its completion, cracks began to form. Rainwater seeps through the deck cracks onto the cover beams, and the rainwater seeps into the top surface of the cover beams and mixes with dust in the air to form mud, causing moisture to be stored on the top and sides of the cover beams for a long period of time, and gradually infringes the cover beam concrete and Reinforcing steel greatly reduces the durability of the cover beam, thus affecting the safety of the entire bridge structure.
The ECS deck continuous installation is installed one-time before the concrete leveling layer is placed on the bridge deck to ensure the smoothness of the deck pavement at the joints. When the concrete is poured, it is used as a pouring bottom mold to prevent the concrete slurry from infiltrating, and no additional support template is needed. After completion of the bridge asphalt pavement, due to the tensile properties of the device itself, when the temperature changes in the four seasons cause the beam to expand and contract, it can resist the tensile stress due to this; due to the device's high elastic air cushion effect, when the live load effect When the beam plate is flexed and rotated, the bending moment effect of the continuous part can be reduced, and the possibility of cracks in the pavement layer is reduced. There is a drainage pipe under the device, and the dry external environment enhances the durability of the cover beam. Especially for the cover beams with cracks, the dry environment avoids corrosion of the steel bars and ensures the bearing capacity of the cover beams.
Saving maintenance cost The above advantages of the device ensure that the bridge surface is continuously damaged from the surface layer, ensuring the comfort of driving, and at the same time, the water damage of the cover beam is eliminated and the bridge maintenance cost is saved. Durability ECS uses a highly durable, highly elastic material to ensure that the device is continuously in good working condition.
