Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to an underwater expansion joint structure of a bridge. Background Art

[0002] In bridge engineering, in order to ensure that the concrete shrinkage or stretching caused by temperature changes or load changes in the bridge structure under normal use is prevented, it is necessary to set gaps between the main beams of the bridge and install expansion joints or expansion devices in these gaps so that the bridge structure can deform freely, thereby ensuring the smooth passage of vehicles on it. However, dirty water is easily stored in the expansion joints, which is not convenient for workers to clean and also affects the long-term use of the expansion joints. Therefore, a bridge underwater expansion joint structure is proposed to solve the above problem. Utility Model Content

[0005] As a preferred embodiment of the utility model, a plurality of first elastic telescopic rods are fixedly connected between the lifting plate and the base plate, and the first elastic telescopic rods can elastically shrink, thereby ensuring that the lifting plate will not be damaged when the bridge is deformed up and down or the baffle is pressed by a heavy object.

[0008] As a preferred embodiment of the present invention, the side panel is provided with a plurality of mounting holes which penetrate the side panel up and down, and the mounting holes are used for mounting and fixing the side panel.

[0009] As a preferred embodiment of the utility model, the sliding plate is provided with a water flow groove with openings on the lower side and one side close to each other, and the water flow groove can discharge the water infiltrated by the baffle into the collecting chamber.

[0022] The lower end surface of the baffle 109 is fixedly connected to a sliding plate 108, and a sliding cavity 106 is provided in the lifting plate 105. The sliding plate 108 and the sliding cavity 106 are fixedly provided with a plurality of second elastic telescopic rods 107 near an end wall of the side plate 102. The second elastic telescopic rods 107 can elastically support the sliding plate 108. When the bridge deforms left and right, the second elastic telescopic rods 107 can elastically deform, thereby causing the baffle 109 and the lifting plate 105 to be displaced, thereby avoiding damage to the two baffles 109 while ensuring that the two baffles 109 are in contact with each other.

[0023] A plurality of first elastic telescopic rods 104 are fixedly connected between the lifting plate 105 and the bottom plate 101. The first elastic telescopic rods 104 can elastically shrink, thereby ensuring that the lifting plate 105 will not be damaged when the bridge is deformed up and down or the baffle 109 is pressed by a heavy object.

[0024] The bottom plate 101 is provided with a collecting cavity 103 with an upper opening, and the collecting cavity 103 is inclined toward the center on all sides.

[0028] The working principle and use process of this utility model:

[0029] When in use, the two bottom plates 101 are brought close to each other so that the two baffles 109 abut against each other through the grooves 113 and the convex plates 112. At this time, the two bottom plates 101 are fixed in the bridge gap through the mounting holes 115, and the connecting pipe 116 is connected to the sewer pipe.

[0030] When in use, if the bridge is deformed in the left and right directions, the two baffles 109 are forced to move, and then limited by the guide plate 111, and buffered by the second elastic telescopic rod 107 to avoid damage to the baffles 109, and the baffles 109 and the upper side of the lifting plate 105 can support the work;

[0031] During use, if the bridge is deformed in the up and down directions or is pressed down by a heavy object, the baffle 109 is subjected to the force to drive the lifting plate 105 to move downward, and the deformation of the first elastic telescopic rod 104 is used for buffering to avoid damage to the lifting plate 105 and the baffle 109, and the second elastic telescopic rod 107 and the lifting plate 105 can drive the baffle 109 to return to its original position after the deformation is completed.
