Description
Technical Field
[0001] The utility model relates to the technical field of bridge expansion joints, in particular to a bridge expansion joint with an anti-water seepage structure. Background Art
[0002] In order to meet the requirements of bridge deck deformation, workers usually set expansion joints at the hinged positions of the bridge deck to adjust the displacement and connection between the superstructures caused by vehicle loads and bridge construction materials. Existing bridge expansion joints are usually composed of special-shaped steel, waterstops and anchoring mechanisms.
[0003] For example: The utility model with application number CN202022083423.8 discloses a bridge expansion joint, which specifically includes special-shaped steel, waterstop, anchoring mechanism, and crossbeam mechanism; the special-shaped steel includes side beams and center beams; the center beam is arranged between the two side beams; the waterstop is arranged between the center beam and the side beam, the anchoring mechanism is arranged on the side beam, and the crossbeam mechanism is arranged at the lower part of the special-shaped steel; a plurality of movable plate grooves are arranged at the bottom of the side beam, a square through hole is arranged on one side of the movable plate groove, and a card slot is arranged at the bottom of the center beam; the anchoring mechanism includes an anchor, a movable plate, and a bolt; the anchor is arranged on the outside of the side beam, the movable plate is arranged in the movable plate groove, the bolt is arranged on the movable plate, and the bolt is connected to the anchor.
[0004] However, as far as the current traditional bridge expansion joints are concerned, the bridge expansion joints are set up to adapt to the thermal expansion and contraction of bridges or building structures, and usually have certain openings or gaps. During long-term use, due to the effects of natural factors such as wind, rain, and sun, as well as the influence of traffic activities such as vehicles and pedestrians, dust, sand, garbage and other debris are easily accumulated in the bridge expansion joints. In order to prevent the debris from affecting the normal use of the bridge expansion joints, staff are usually required to clean up the debris in the bridge expansion joints regularly, which is cumbersome to operate and inconvenient to use. Utility Model Content
[0005] In view of this, the utility model provides a bridge expansion joint with an anti-seepage structure, which is provided with a diverter seat that can automatically clean up debris in the bridge expansion joint. When a vehicle passes through the bridge expansion joint, the control pressure block will be pressed down, so that the control pressure seat drives the connecting slider to slide in the aluminum alloy base. As the connecting slider slides, the diverter seat will be driven to move downward. In the process of movement of the control pressure seat, the guide slide column will be driven to slide in the fixed seat and press down the reset spring through the pressure plate. In the process of movement of the control pressure seat, the connecting rocker arm will also be driven to swing. The swing belt of the connecting rocker arm assists the slider to slide along the auxiliary slider and squeeze the connecting spring. After the vehicle passes through the bridge expansion joint, the control pressure seat will rebound and reset under the action of the reset spring and the elastic potential energy of the connecting spring itself. As the control pressure seat rebounds, the diverter seat will be driven to rebound through the connecting slider. The rebound of the diverter seat will eject the debris and garbage intercepted or filtered on the diverter seat into the bridge expansion joint, thereby ensuring the cleanliness of the bridge expansion joint.
[0006] The utility model provides a bridge expansion joint with an anti-water seepage structure, which specifically comprises: a bridge body; two aluminum alloy bases are symmetrically bolted in the bridge body; the bottom end surfaces of the two aluminum alloy bases are fixedly connected with a connecting bottom plate; an auxiliary seat is arranged between the lower parts of the two aluminum alloy bases; a diverter seat is arranged between the upper parts of the two aluminum alloy bases; the positions of the diverter seat and the auxiliary seat are aligned; a fixed seat is centrally fixedly connected in the lower parts of the two aluminum alloy bases; a group of guide rods are symmetrically fixedly connected to the outsides of the two fixed seats; the ends of the two groups of guide rods are respectively fixedly connected in the two aluminum alloy bases; and a control pressure seat is slidably connected in the upper parts of the two aluminum alloy bases.

[0009] Optionally, the top end surfaces of the two control pressure seats are fixedly connected to a control pressure block; the inner sides of the two control pressure seats are fixedly connected to a connecting slider; the two connecting sliders are respectively slidably connected to the inner sides of the two aluminum alloy bases; the ends of the two connecting sliders are fixedly connected to the outside of the diverter seat.

[0012] Beneficial Effects
[0013] During use, the utility model diverts water that penetrates into the expansion joint of the bridge through the arrangement of the diverter seat and the diverter groove, and at the same time cleans up debris in the water through the seepage holes, and the cleaned water is discharged through the guide seat to prevent it from penetrating into the interior of the expansion joint of the bridge. At the same time, the cleaned water can be conveniently recycled, thereby effectively improving the practicality of the expansion joint of the bridge.
[0014] When a vehicle passes through the expansion joint of the bridge deck, the control pressure block will be pressed down, and then a series of transmissions will be used to move the diverter seat, and the reset spring and the connecting spring will be compressed. After the vehicle is away from the expansion joint of the bridge, the control pressure seat will rebound and reset under the action of the reset spring and the connecting spring's own elastic potential energy, and drive the diverter seat to rebound. During the rebound of the diverter seat, the debris and garbage intercepted or filtered out of the diverter seat will be ejected out of the expansion joint of the bridge to ensure the cleanliness of the expansion joint of the bridge. At the same time, vibration will be generated during the rebound of the diverter seat to prevent the seepage holes from being blocked by mud or silt, effectively improving the convenience of the expansion joint of the bridge and extending the service life of the expansion joint of the bridge.
