Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge, and particularly relates to a waterproof structure for road and bridge design. Background Technique

[0002] A road and bridge generally consists of several major parts such as a roadbed, a road surface, a bridge, a tunnel project, and traffic engineering facilities. When constructing a road and bridge, waterproof design needs to be considered to avoid water accumulation above the road and bridge affecting driving safety. Existing bridges are usually pre-cast into an arch shape, and then multiple bridge bodies are respectively erected on the bridge columns pre-cast on the ground and docked. Gaps will be generated at the docking joints of the two bridge bodies, and the water on the bridge surface mostly flows out through the gaps at the docking joints of the two bridge bodies. The current treatment method is mostly to directly pour caulking glue into the gaps for sealing, but the caulking glue is easy to fall off after long-term use, resulting in a decline in the waterproof effect at the gaps of the docking joints of the two bridge bodies.

[0003] After retrieval, in the Chinese patent with the publication number of CN 221167433 U, a waterproof structure for road and bridge design is mentioned, which includes an extrusion plate, a U-shaped frame, and two bridge bodies. The extrusion plate is clamped between the two bridge bodies, and fixing components for fixing the extrusion plate to the two bridge bodies are arranged on both sides of the extrusion plate. The U-shaped frame is located at the bottom of the extrusion plate, and rubber pads are bonded to both sides of the U-shaped frame. In this scheme, by rotating two hexagon socket head cap nuts, a spiral thrust is applied to two internal thread cylinders during the rotation process of the two hexagon socket head cap nuts, so that the two internal thread cylinders drive the U-shaped frame to approach the extrusion plate. At this time, the bottom end of the extrusion plate will abut against the U-shaped frame and cause it to open, and then the rubber pads on both sides of the U-shaped frame will respectively abut tightly against the opposite sides of the two bridge bodies, thereby sealing the gap between the two bridge bodies and achieving the waterproof effect.

[0004] The above device has drawbacks in the specific use process. Since the docking joints of the bridge are prone to deformation, the gaps at the docking joints will change accordingly, further squeezing and deforming the waterproof structure board installed at the docking joints, and over time, the structure will be damaged.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model fixes a flexible waterproof plate between two waterproof strips. When the two bridge bodies are deformed and the butt gap becomes smaller, the flexible waterproof plate is made of rubber material and has good waterproof and deformation capabilities, thereby avoiding damage to the internal hard waterproof structure. A sealed environment is formed by arranging a U-shaped sealing groove, an L-shaped sealing pad and a solid sealing block, thereby playing a waterproof role.
