Problems solved by technology
The sealing rubber belt of the expansion device is easy to age and needs to be replaced frequently. However, due to the different traffic flow, road surface load, and uneven temperature of the road surface, the deformation of different parts of the expansion device is also different, which brings many difficulties to the replacement of the sealing rubber belt. The replacement period is long, and circuit breaker construction is required
Secondly, the daily maintenance of special-shaped steel expansion devices requires frequent cleaning of debris accumulated between the joints, which not only increases the maintenance workload, but also increases the safety hazards of maintenance workers

The invention discloses a sealing protection structure of a highway bridge expansion device. The sealing protection structure comprises a first supporting plate, a second supporting plate is arrangedon the right side of the first supporting plate, a first supporting box is arranged on the left side of the lower surface of the first supporting plate, and a second supporting box is arranged on theright side of the lower surface of the second supporting plate; and two first expansion blocks arranged in a front-rear symmetrical mode are arranged at the front end and the rear end of the left sideface of the second supporting plate, and second expansion blocks are arranged in the middle of the right side face of the first supporting plate, wherein the second expansion blocks and the first expansion blocks are arranged correspondingly in an engaged mode. According to the sealing protection structure of the highway bridge expansion device, the structure is simple, mounting and maintenance are convenient, and the highway bridge expansion device can be effectively sealed; through arrangement of anti-sliding stripes, sliding of a vehicle on the upper surface of the sealing protection structure can be effectively avoided; mounting and fixing of the sealing protection structure are facilitated through arrangement of U-shaped positioning steel bars; and external rubbish can be effectivelyprevented from entering the interior of expansion joints through arrangement of a first arc-shaped plate and a second arc-shaped plate.
Description
technical field [0001] The invention relates to the technical field of bridge expansion devices, in particular to a sealing and protection structure for highway bridge expansion devices. Background technique [0002] Most of the existing road bridge expansion devices are modular road bridge expansion devices, and their structures are composed of special-shaped steel and sealing rubber belts. The sealing rubber belt of the expansion device is easy to age and needs to be replaced frequently. However, due to the different traffic flow, road surface load, and uneven temperature of the road surface, the deformation of different parts of the expansion device is also different, which brings many difficulties to the replacement of the sealing rubber belt. The replacement period is long, and circuit breaker construction is required. Secondly, the daily maintenance of special-shaped steel expansion devices requires frequent cleaning of debris accumulated in the gaps, which not only i...
