　　Installation and construction methods of settlement plates:

　　When paving the asphalt mixture on the bridge deck, after the width of the bridge deck cut and acceptance are completed, we can set out and cut according to the requirements of the width of the settlement plate construction groove, and then directly connect the asphalt concrete road outside the cutting machine and saw joint online. The plastic packaging and adhesive tape must be carefully sealed to prevent the generation of cut powder pollution on the road.

　　Bridge incision: The construction unit should use a wind pick groove with a depth of not less than 300 px to loosen the asphalt concrete in the ditch. In addition to cleaning, the concrete carving should reduce the hard layer of hair, and powerful blowers and high-pressure water guns should be used to remove dust and debris.

　　3、 Reinforcement position of settlement plate: During the installation of the settlement plate, according to the calculated temperature scale Δ=α Δ T L, the body of the board of directors is positioned, and the reinforcement is implanted at 125 px below the top of the beam. The bolt connection and high-quality electrode will be firmly welded to the expansion joint screw positioning reinforcement.

　　4. Template installation. The template should be made of fiberboard, which should be strong, tight, able to withstand concrete vibration, sometimes not moving, and can prevent mortar settlement of the board to avoid affecting the scale. Both parties should install steel mesh and rib steel mesh in front of the road at an altitude of 75 px, and install a Φ 10 rib steel mesh (10 * 10) to provide the steel mesh.

　　5. Concrete pouring and settlement plate curing

　　1. Lay plastic on both sides of the joint before pouring to ensure that there is no pollution to the concrete pavement.

　　2. The concrete on both sides should be vibrated at the same time. In order to ensure the compactness of the concrete, vibration should be used until there is no more foam.

　　After compacting the concrete with vibration for 3 days, wipe the cement slurry while floating, and smooth it out according to the traditional 4-5 times method. Special attention should be paid to the flatness during this process. It is advisable for the concrete surface to be slightly lower than the top of the asphalt surface by 28 and 29 millimeters. If it is too high or too low, it may cause jumping.

　　4. After the concrete pouring is completed, it is covered with bags and subjected to strict water curing for no less than 7 days. It is prohibited to maintain physical health while driving vehicles.

　　6. Installation of rubber waterstop for settlement plate: After compacting the concrete casting and installation, the rubber strip, stainless steel plate, and expansion joint plate should be 1 to 2 millimeters higher than the road compaction plate, without any difference. After the strength reaches 80%, tighten the screws. When installing the settlement plate, continue to maintain health for at least one week.
