Description

Technical Field

[0001] The utility model relates to the technical field of subway construction, in particular to a rubber pressure strip of a rubber road slab of a railway level crossing. Background Art

[0002] Subway construction is the process of building subway lines, stations or related facilities underground or on the ground in the city, including planning and design, land expropriation, geological survey, tunnel excavation, etc., through professional technology and precise engineering operations to ensure the safe, stable and efficient operation of the subway line. The intersection between the railway and the normal road will be a railway level crossing. Rubber slabs will be used on the road surface of the railway level crossing to protect the road. The rubber pressure strip refers to a rubber sealing strip installed under the rubber slab of the railway level crossing, which is used to fill the gap between the rubber slab and the road, and plays a role in sealing, shock absorption and waterproofing.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN220349685U discloses a plastic pressure strip for impact-resistant flooring for rail vehicles, which belongs to the field of subway construction. Its technical points include a first impact-resistant floor, a second impact-resistant floor is arranged on the left side of the first impact-resistant floor, and the opposite sides of the first impact-resistant floor and the second impact-resistant floor are fixedly connected with auxiliary connecting plates, and a card slot is provided inside the auxiliary connecting plate. When in use, the plastic pressure strip for impact-resistant flooring for rail vehicles is provided with a first impact-resistant floor, a second impact-resistant floor, a pressure strip body, a movable rod, a placement cavity and a spring. Through the mutual cooperation of the components, a stable connection between the main body of the plastic pressure strip for impact-resistant flooring for rail vehicles and the first impact-resistant floor and the second impact-resistant floor is achieved. At the same time, facing the thrust generated by the first impact-resistant floor or the second impact-resistant floor, the movable rod will shrink to provide a buffer for the pressure strip body, thereby improving the stability of the plastic pressure strip for impact-resistant flooring for rail vehicles.

[0004] At present, most rubber strips on the market still have certain shortcomings when used. As shown in the above-mentioned documents, the thrust generated by the first impact-resistant floor or the second impact-resistant floor will cause the movable rod to contract, providing buffering for the strip body, thereby improving the stability of the impact-resistant floor plastic strip for rail vehicles. This method has a relatively simple structure, and the buffering effect of a single spring is limited, and it cannot improve the durability of the rubber strip well. Secondly, this method is not stable in fixing, and the vibration of the road surface can easily cause the vibration of the road plate rubber strip, which may cause the road plate to loosen and deviate, and there are certain shortcomings in use.
