Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge expansion joints, and particularly relates to a V-shaped drainage structure for bridge expansion joints. Background Art
[0002] A bridge expansion joint refers to a joint set between two beam ends, between a beam end and an abutment, or at the hinge position of a bridge to meet the requirements of bridge deck deformation. The function of a bridge expansion joint is to adjust the displacement and connection between the superstructures caused by vehicle loads and bridge building materials. Generally, bridge expansion joints include butt joints, steel support types, combined shear types, modular support types, and elastic devices, etc.
[0003] The existing bridge expansion joints are horizontally extended, and water is likely to accumulate inside the expansion joint. After long-term use, the accumulated water will penetrate and corrode the wall surface of the expansion joint, leading to a reduction in the service life of the expansion joint.
[0004] At present, the Chinese utility model with the publication number: CN217629411U discloses a transverse drainage structure for bridge expansion joints, belonging to the technical field of expansion joint drainage. It includes a first section steel and a second section steel. A gap between the first section steel and the second section steel forms an expansion joint. A water diversion member is arranged inside the expansion joint. Two oppositely arranged grooves are opened on the first section steel and the second section steel. Both sides of the water diversion member are arranged in the two grooves. Clamping blocks are inserted into the two grooves on the first section steel and the second section steel. The bottom of the first section steel and the second section steel is fixedly provided with a bridge body. Drain pipes are fixedly arranged on both sides of the first section steel and the second section steel on the bridge body. A water collecting pipe connected to the water diversion member is detachably installed at the top of the drain pipe. Road surface water enters the expansion joint, flows to the surface of the water diversion member, and the accumulated water is drained horizontally to both sides through two water diversion strips, flows into the water collecting pipe, and after being filtered by a filter screen inside the water collecting pipe, then flows into the drain pipe for drainage, reducing the damage to the expansion joint caused by long-term accumulation of water.
[0005] Regarding the above problems, the existing patents have provided solutions. During the installation and use of the drainage structure, most of the existing drainage structures are fixedly installed inside the expansion joint. However, during actual use, the beam bodies at both ends of the expansion joint are prone to dislocation movement. Therefore, the drainage structure cannot be adjusted according to the movement of the expansion joint, which easily leads to damage to the drainage structure, thereby affecting the subsequent drainage. Therefore, it is not conducive to the use of staff. Moreover, during the use of the drainage structure, it usually does not have a filtering effect inside. Therefore, during long-term use, sundries usually fall into the drainage structure through the expansion joint, resulting in blockage of the drainage structure. Due to the blockage inside the drainage structure, water is likely to accumulate inside the expansion joint. After long-term use, the accumulated water will penetrate and corrode the wall surface of the expansion joint, leading to a reduction in the service life of the expansion joint.
[0006] For this reason, a V-shaped drainage structure for bridge expansion joints is proposed. Content of the Utility Model

Therefore, it is not conducive to the use of the staff. Moreover, during the use of the drainage structure, it usually does not have a filtering effect. Therefore, during long-term use, sundries usually fall into the drainage structure through the expansion joint, resulting in blockage of the drainage structure. Due to the blockage inside the drainage structure, water accumulation is likely to accumulate inside the expansion joint.

Detailed implementation mode
[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0027] Please refer to Figures 1-5 , the present invention provides a technical solution:
[0028] A V-shaped drainage structure for bridge expansion joints includes a bridge body 1. An expansion joint body 2 is arranged inside the bridge body 1. A V-shaped drainage trough 3 is arranged inside the expansion joint body 2. Installation components 4 are arranged on both sides of the V-shaped drainage trough 3. A filtering component 5 is arranged inside the V-shaped drainage trough 3. A segmented block 6 is bolted to the top of the V-shaped drainage trough 3;
[0029] The installation component 4 includes an installation block 401, a connecting spring 402, a connecting block 403, an installation plate 404 and a fixing bolt 405. The installation block 401 is bolted to both sides of the V-shaped drainage trough 3. A connecting spring 402 is fixedly connected to the outside of the installation block 401. A connecting block 403 is bolted to the outside of the connecting spring 402. An installation plate 404 is bolted to the outside of the connecting block 403. A fixing bolt 405 is threadedly connected to the inside of the installation plate 404. The outside of the fixing bolt 405 is threadedly connected to the bridge body 1.
[0030] In this embodiment: By providing a bridge body 1, an expansion joint body 2, a V-shaped drainage trough 3, a mounting assembly 4, a filtering assembly 5, and a segmented block 6, the staff can install the V-shaped drainage trough 3 inside the expansion joint body 2 on the inner side of the bridge body 1 through the mounting assembly 4. During the installation and use of the drainage system, fine adjustment can be made to the connecting components between the drainage structure and the bridge. Therefore, the drainage structure can be adjusted according to the movement of the expansion joint, thus avoiding damage to the drainage structure and having no impact on the subsequent drainage of the drainage structure. This is beneficial for the staff to use. Then, by installing the filtering assembly 5 and the segmented block 6, effective filtering can be achieved inside the drainage structure during its use. Therefore, debris will not fall into the drainage structure through the expansion joint due to long-term use, thus preventing blockage of the drainage structure. As a result, water accumulation will not occur inside the expansion joint, and thus the penetration and corrosion of the expansion joint wall by the accumulated water can be avoided, thereby extending the service life of the expansion joint.
[0031] Specifically, as Figure 3 shown, the filtering assembly 5 includes sliding grooves 501 which are respectively opened on the inner side of the V-shaped drainage trough 3. A double-headed motor body 502 is bolted to the inner side of the segmented block 6. On both sides of the double-headed motor body 502, screw rods 503 are bolted. The outer sides of the screw rods 503 penetrate through the inner side of the segmented block 6 and are threadedly connected to the inner side of the sliding grooves 501. Inside the sliding grooves 501, sliding blocks 504 are slidably connected. The sliding blocks 504 are threadedly connected to the outer sides of the screw rods 503. Inside the sliding blocks 504, a frame 505 is bolted. Inside the frame 505, a filter plate 506 is rotatably connected.
[0032] Specifically, as Figure 3 shown, a protective shell 7 is sleeved on the outer side of the double-headed motor body 502. The protective shell 7 is made of stainless steel.
[0033] Specifically, as Figure 3 shown, alignment blocks 8 are bolted to the inner side of the frame 505. Alignment grooves 9 are opened on both sides of the segmented block 6. The alignment blocks 8 are inserted into the inner sides of the alignment grooves 9.
[0034] In this embodiment: By providing a sliding groove 501, a dual-head motor body 502, a screw 503, a sliding block 504, a frame 505, a filter plate 506, a protective shell 7, an alignment block 8, and an alignment groove 9, when the staff starts the dual-head motor body 502 to drive the screw 503 to rotate, the frame 505 and the filter plate 506 inside the sliding block 504 can be driven to slide inside the sliding groove 501. During the use of the drainage structure, effective filtration inside it can be achieved. Therefore, debris will not fall into the drainage structure through the expansion joint due to long-term use, thus preventing the drainage structure from being blocked. As a result, water accumulation will not occur inside the expansion joint, and thus the penetration and corrosion of the expansion joint wall surface caused by water accumulation can be avoided, thereby increasing the service life of the expansion joint. By providing the protective shell 7, the dual-head motor body 502 can be protected, thereby increasing the service life of the dual-head motor body 502. By providing the alignment block 8 and the alignment groove 9, it can be ensured that the frame 505 will not shift during installation, which is conducive to the staff installing the frame 505.
[0035] Specifically, as Figure 5 shown, an arc-shaped groove 10 is provided inside the frame 505, and an arc-shaped block 11 is bolted to the outside of the filter plate 506. The arc-shaped block 11 is slidably connected inside the arc-shaped groove 10.
[0036] Specifically, as Figure 5 shown, a limiting plate 12 is rotatably connected to the bottom of the frame 505, and the top of the limiting plate 12 contacts the bottom of the arc-shaped block 11.
[0037] In this embodiment: By providing the arc-shaped groove 10 and the arc-shaped block 11, it is convenient for the staff to rotate the filter plate 506, so as to facilitate the staff to clean the debris inside. By providing the limiting plate 12, the filter plate 506 can be limited to prevent the filter plate 506 from rotating.
[0038] Specifically, as Figure 4 shown, a diversion plate 13 is bolted inside the V-shaped drainage groove 3, and guide plates 14 are bolted to both sides of the diversion plate 13.
[0039] Specifically, as Figure 1 shown, a waterproof plate 15 is fixedly connected inside the bridge body 1, and the waterproof plate 15 is made of stainless steel.
[0040] In this embodiment: By providing the diversion plate 13 and the guide plates 14, the water inside the V-shaped drainage groove 3 can be diverted, which is conducive to discharging the water inside. By providing the waterproof plate 15, the entry of accumulated water into the bridge body 1 can be reduced, thus avoiding damage to the bridge body 1.
[0041] Working principle: During the installation of the drainage structure by the staff, the staff install the installation blocks 401 on both sides of the V-shaped drainage groove 3, then install them through the connecting springs 402 and the connecting blocks 403, and then install the mounting plate 404 on the inner side of the expansion joint body 2 through the fixing bolts 405. It can be realized that during the installation and use of the drainage structure, the connectors between the drainage structure and the bridge can be finely adjusted. Therefore, the drainage structure can be adjusted according to the movement of the expansion joint, thus avoiding damage to the drainage structure and having no impact on the later drainage of the drainage structure. Therefore, it is beneficial for the staff to use. Then, by starting the double-headed motor body 502 to drive the screw 503 to rotate, the frame 505 and the filter plate 506 inside the sliding block 504 can be driven to slide inside the sliding groove 501. It can be realized that during the use of the drainage structure, its interior can be effectively filtered. Therefore, debris will not fall into the drainage structure through the expansion joint due to long-term use, thus avoiding blockage of the drainage structure. Therefore, water accumulation will not accumulate inside the expansion joint, thus avoiding the penetration and corrosion of the expansion joint wall surface by the accumulated water. Therefore, the service life of the expansion joint is extended.
[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
