Construction of ECS Implantable Continuous Device for Bridge Deck
ECS implantable bridge deck continuous device is a product for bridge structure produced by our Hengshui Yifeng Technology, also known as special rubber waterstop for bridge deck, which belongs to a kind of waterstop and is used on beam bridges. It includes a rubber plate made of elastic material, a drain groove is provided in the middle or near the middle of the rubber plate, and a drain hole communicating with the drain groove is opened on the rubber plate. It includes an arched structure, on both sides of the arched structure is provided with a mounting surface for connecting with the bridge deck beam body, and an I-beam-shaped rib is arranged above the arched structure at a certain distance along the width direction. hsyfxj2345631
Construction steps of ECS implantable bridge deck continuous device:
Step 1: Cut out the original continuous bridge deck;
Step 2: Leveling within the continuous range of the original bridge deck to remove impurities
Step 3: Flatten the ECS continuous telescopic device we prepared in advance, and remove the rust of the steel bar;
Step 4: Install ECS implantable bridge deck continuous device;
Step 5: Extend the drainage pipe of the ECS continuous telescopic device out of the guardrail;
Step 6: Install the upper reinforcement mesh and erecting reinforcement, and perform welding;
Step 7: Pouring bridge deck concrete
ECS implantable bridge deck continuous device structure design, considering the following 5 working conditions:
1) Shrinkage or elongation of simply supported beams caused by changes in overall temperature. The resulting stress meter is σw.
2) Tensile and compressive stress on continuous parts of bridge deck caused by automobile braking force. The resulting stress meter is σz.
3) The deflection angle effect caused when the lane load is full of two adjacent spans, the corner deformation will cause the bending stress of the continuous part to be pulled at the upper edge and compressed at the lower edge. The resulting stress meter is σq.
4) The positive temperature difference in the effect of gradient temperature will cause the deflection angle effect on the beam end, which will cause the upper edge to be compressed and the lower edge to be pulled; the reverse temperature difference effect is just the opposite. The resulting stress meter is σt.
5) The local force effect caused by the wheel load on the continuous deck. The resulting stress meter is σj.
