Description

Technical Field

[0001] This utility model relates to the field of bridge seepage prevention technology, specifically a road seepage prevention structure for road and bridge engineering. Background Technology

[0002] In the field of road and bridge engineering, the seepage prevention treatment at bridge deck joints is a key technology affecting structural durability and safety. Existing bridge deck joint sealing structures generally suffer from the following technical defects: First, traditional fixing devices are prone to displacement and relaxation under long-term loads, leading to gaps between the sealing joint and the sealing components. This fails to effectively prevent rainwater from seeping into the bridge structure, accelerating steel corrosion and concrete deterioration. Second, conventional sealing materials lack deformation compensation mechanisms, making it difficult to adapt to the periodic deformation caused by thermal expansion and contraction of the bridge deck, easily leading to cracking and failure of the sealing layer. Third, existing seepage prevention structures generally neglect the transmission of vibration and noise generated by vehicle traffic, lacking active noise reduction design, causing a continuous impact on the surrounding acoustic environment. Furthermore, the installation and positioning of most sealing devices rely on the accuracy of embedded parts, resulting in insufficient on-site adjustment capabilities and difficulty in achieving effective sealing when bridge deck construction errors are large. These technical bottlenecks severely restrict the service life and environmental friendliness of bridge structures, necessitating the development of new seepage prevention structural systems with self-adjusting functions, multiple sealing mechanisms, and noise reduction characteristics. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a seepage-proof structure with adaptive adjustment, dynamic buffering and noise reduction synergistic effects.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a road seepage prevention structure for road and bridge engineering, including bridge decks, with a retaining joint between the bridge decks, an expansion joint in the retaining joint, a seepage prevention plate fixedly connected to the upper end of the expansion joint, the seepage prevention plate being fitted to the surface of the bridge deck, and fitting grooves respectively opened on the surface of the bridge deck on both sides of the seepage prevention plate, the two sides of the seepage prevention plate being fitted into the fitting grooves respectively, rubber pads fixedly connected to both sides of the seepage prevention plate, the lower end of the rubber pads abutting against the bottom surface of the fitting groove, and a plurality of sound-absorbing holes opened in the seepage prevention plate, each sound-absorbing hole being filled with a sound-absorbing cotton swab. In this structure, the expansion section deforms to both sides to be embedded in the sealing joint, thus fixing the seepage-proof structure relatively between the two bridge plates. At the same time, it ensures that the two sides of the expansion section are tightly fitted to the inner wall of the sealing joint. The upper end of the expansion section is fixedly connected to a seepage-proof plate, which further prevents rainwater and other liquids from entering the sealing joint. The bridge plates on both sides of the seepage-proof plate are provided with fitting grooves, and the recessed structure can prevent rainwater from flowing towards the sealing joint. In addition, a rubber pad is provided between the fitting groove and the seepage-proof plate, which can further facilitate water penetration. The sound-absorbing holes and sound-absorbing cotton swabs in the seepage-proof plate can effectively reduce the noise generated when vehicles pass by and improve environmental comfort.

[0005] In the above technical solution, the expansion part includes an upper connecting block, a lower connecting block, a flexible plate, a threaded sleeve, a threaded rod, a first hinge plate, a second hinge plate, a third hinge plate, a rotating shaft block, and an internal hexagonal nut. The upper connecting block is fixedly connected to the lower center of the seepage-proof plate. Flexible plates are fixedly connected to both sides of the upper connecting block. The lower ends of the flexible plates are fixedly connected to both sides of the lower connecting block. A hinge base is embedded in the lower connecting block. The first hinge plate is rotatably connected to both sides of the hinge base. A second hinge plate is rotatably connected to the upper end of the first hinge plate. A hinge plate is provided, and a third hinge plate is rotatably connected to the upper end of the second hinge plate. The third hinge plate is rotatably connected to both sides of the hinge top seat. The hinge top seat is embedded in the lower end of the upper connecting block. An operating hole is provided in the middle of the upper end of the seepage-proof plate. An internal hexagonal nut is rotatably connected in the operating hole. A threaded rod is fixedly connected to the middle of the lower end of the internal hexagonal nut. The threaded rod passes through the upper connecting block and the hinge top seat in sequence and is rotatably connected between the two flexible plates. A threaded sleeve is fixedly connected to the middle of the upper end of the hinge base. The lower end of the threaded rod is threadedly connected to the threaded sleeve.

[0006] In the above technical solution, several sliding sleeves are fixedly connected to the hinge bases on both sides of the screw sleeve, and sliding guide rods are slidably connected inside the sliding sleeves. The upper ends of the sliding guide rods are fixedly connected to the lower ends of the hinge top seats respectively.

[0007] In the above technical solution, a dust cap is closed and connected inside the opening at the upper end of the operating hole.

[0008] In the above technical solution, the anti-seepage plate has reserved holes, and the bolts are threaded into the bridge plate after passing through the reserved holes.

[0009] In the above technical solution, buffer vesicles are fixedly connected to both sides of the flexible plate, and several uniformly arranged air cavities are provided inside the buffer vesicles.

[0010] The beneficial effects of this utility model are:

[0011] 1. Adaptive embedding seal enhances seepage prevention reliability: Through the linkage adjustment mechanism of the threaded rod and the threaded sleeve in the expansion section, the flexible plate can be actively controlled to expand outward, so that the expansion section fits tightly against the inner wall of the embedding joint, effectively compensating for gaps caused by construction errors and long-term loads, significantly enhancing the sealing performance, preventing rainwater from seeping into and eroding the internal structure of the bridge, and extending the service life of the bridge.

[0012] 2. Dynamic buffering and deformation resistance, adapting to complex working conditions: The buffer bladders set on both sides of the flexible plate can absorb the displacement stress caused by thermal expansion and contraction or vibration of the bridge plate through the elastic deformation of the internal air cavity, avoid cracking and failure of the sealing structure, and ensure the long-lasting sealing effect of the caulking joint under dynamic load.

[0013] 3. Multiple noise reduction designs improve environmental friendliness: The sound-absorbing holes of the sound-absorbing cotton rods embedded in the seepage-proof board can efficiently absorb the vibration noise generated when vehicles pass by. Combined with the damping and energy dissipation effect of the flexible board and buffer bubble, noise transmission is reduced in multiple dimensions, improving the comfort of the sound environment around the bridge.

[0014] 4. Modular and adjustable structure for convenient and efficient construction: The expansion section can be quickly installed and its tightness adjusted by driving the threaded rod through the internal hexagonal nut in the operating hole, reducing the dependence on the accuracy of the embedded parts; the pre-drilled holes of the anti-seepage board are fixed with bolts, further simplifying the on-site construction process and adapting to the installation requirements of different bridge plate joints.

[0015] 5. Redundant seepage barrier for enhanced durability: The interlocking groove and rubber gasket form a double water-blocking interface. Combined with the seepage barrier board that fully covers the top of the interlocking joint, a multi-layer seepage prevention system is constructed to effectively intercept rainwater infiltration paths and reduce maintenance frequency and costs.

[0023] Please see Figure 1-5 A road seepage prevention structure for road and bridge engineering includes a bridge deck 1, with a sealing joint 2 between the bridge decks 1. An expansion joint 3 is provided in the sealing joint 2, and a seepage prevention plate 4 is fixedly connected to the upper end of the expansion joint 3. The seepage prevention plate 4 is adhered to the surface of the bridge deck 1. Fitting grooves 5 are respectively opened on the surface of the bridge deck 1 on both sides of the seepage prevention plate 4, and the two sides of the seepage prevention plate 4 are respectively fitted into the fitting grooves 5. Rubber pads 6 are fixedly connected to both sides of the seepage prevention plate 4, with the lower ends of the rubber pads 6 abutting against the bottom surface of the fitting grooves 5. Several sound-absorbing holes 7 are opened inside the seepage prevention plate 4, and each sound-absorbing hole 7 is filled with sound-absorbing cotton swabs 8. In this invention, the expansion joint 3 is fixedly fitted into the bridge deck 1 by deforming to both sides. In the sealing joint 2, the seepage prevention structure can be relatively fixed between the two bridge plates 1, while ensuring that the two sides of the expansion part 3 are tightly fitted with the inner wall of the sealing joint 2. The upper end of the expansion part 3 is fixedly connected to the seepage prevention plate 4. The seepage prevention plate 4 can further prevent rainwater and other liquids from entering the sealing joint 2. The bridge plates 1 on both sides of the seepage prevention plate 4 are provided with fitting grooves 5. The recessed structure can prevent rainwater from flowing towards the sealing joint 2. In addition, a rubber pad 6 is provided between the fitting groove 5 and the seepage prevention plate 4, which can further facilitate water penetration. The sound-absorbing holes 7 and sound-absorbing cotton swabs 8 in the seepage prevention plate 4 can effectively reduce the noise generated when vehicles pass by and improve the environmental comfort.

[0024] In the above technical solution, the expansion part 3 includes an upper connecting block 101, a lower connecting block 102, a flexible plate 103, a threaded sleeve 104, a threaded rod 105, a first hinge plate 106, a second hinge plate 107, a third hinge plate 108, a rotating shaft block 109, and an internal hexagonal nut 110. The upper connecting block 101 is fixedly connected to the lower center of the seepage-proof plate 4, and the flexible plates 103 are fixedly connected to both sides of the upper connecting block 101. The lower ends of the flexible plates 103 are fixedly connected to the lower connecting block 102. Hinges 111 are fixedly connected to both sides of the connecting block 102. A first hinge plate 106 is rotatably connected to both sides of the hinge base 111. A second hinge plate 107 is rotatably connected to the upper end of the first hinge plate 106. A third hinge plate 108 is rotatably connected to the upper end of the second hinge plate 107. The third hinge plates 108 are rotatably connected to both sides of the hinge top seat 112. The hinge top seat 112 is fixedly connected to the lower end of the upper connecting block 101, preventing leakage. An operating hole 113 is provided at the upper center of plate 4. An internal hexagonal nut 110 is rotatably connected to the operating hole 113. A threaded rod 105 is fixedly connected to the lower center of the internal hexagonal nut 110. The threaded rod 105 passes through the upper connecting block 101 and the hinge top seat 112 in sequence and is rotatably connected between the two flexible plates 103. A threaded sleeve 104 is fixedly connected to the upper center of the hinge base 111. The lower end of the threaded rod 105 is threaded into the threaded sleeve 104. During use, it can be adjusted using a tool. Rotating the internal hex nut 110 causes the threaded rod 105 to rotate, which in turn causes the threaded sleeve 104 to move upward. The threaded sleeve 104 then causes the hinge base 111 and the lower connecting block 102 to move upward. At this time, the first hinge plate 106 and the second hinge plate 107 respectively drive the third hinge plate 108 to move outward, thereby causing the flexible plates 103 on both sides to bulge outward and abut against the inner wall of the caulking joint 2, thus maintaining the relative sealing of the caulking joint 2.

[0025] In the above technical solution, several sliding sleeves 114 are fixedly connected to the hinge bases 111 on both sides of the threaded sleeve 104. Sliding guide rods 115 are slidably connected inside the sliding sleeves 114. The upper ends of the sliding guide rods 115 are fixedly connected to the lower ends of the hinge top seat 112 respectively, so as to ensure the stability of the hinge base 111 and the hinge top seat 112 when they move relative to each other.

[0026] In the above technical solution, a dust cap 116 is closed and connected inside the opening at the upper end of the operating hole 113 to ensure the sealing of the inside of the operating hole 113 after the operation is completed.

[0027] In the above technical solution, the seepage barrier plate 4 has a reserved hole 117. After the bolt passes through the reserved hole 117, it is threaded into the bridge plate 1 to fix the seepage barrier plate 4 to the bridge plate 1 and improve the stability of the device structure.

[0028] The flexible plate 103 is fixedly connected to two sides with buffer bladders 118. The buffer bladders 118 are provided with several uniformly arranged air cavities to adapt to the deformation caused by the thermal expansion and contraction of the bridge plate 1 and to ensure the sealing of the caulking joint 2.
