Description

Technical Field

[0001] This utility model relates to the field of bridge pier water backlog treatment technology, and in particular to a guiding structure for treating water backlog in skew bridge piers. Background Technology

[0002] In actual bridge engineering, skew bridges are widely used in urban and rural roads due to their greater land-saving space and better appearance design. However, the skew design of skew bridges on water surfaces makes it difficult for water to flow naturally, especially when there is a strong current in rivers or canals. The water flow will form eddies or backwater around the bridge piers. This phenomenon will not only affect the stability of the water flow around the bridge piers, but may also cause a large amount of silt to accumulate around the bridge piers, thereby hindering the stability of the bridge and even affecting the safety of the overall bridge structure.

[0003] Existing bridge piers used to support skew bridges are generally located on the main channel of the river, which results in a large water-blocking area and thus a greater impact from the water flow. When the upstream river flow increases, the bridge piers are in a dynamic water environment. The bridge piers are not only hit by floating objects in the upstream river, but also suffer from water accumulation due to their large area. Over time, the concrete of the bridge piers will erode and peel off, and the bridge piers will become unstable in terms of long-term compressive strength.

[0004] The existing patent (publication number: CN222412601U) discloses a guiding structure for water treatment of skew bridge piers, belonging to the technical field of water treatment for skew bridge piers. Its key technical features include a bridge body, with a front fixing sleeve and a rear fixing sleeve respectively provided on the front and rear sides of the pier body. Fixing grooves are provided on both sides of the rear side of the front fixing sleeve. By setting up the pier body, front fixing sleeve, rear fixing sleeve, fixing grooves, fixing blocks, connecting components, and guiding components, the front fixing sleeve is placed close to the front of the pier body and then pulled into the water until its bottom is at the bottom. Then, the rear fixing sleeve is placed on the rear side of the pier body. During this process, the fixing block on the front side of the rear fixing sleeve engages with the fixing groove on the rear side of the front fixing sleeve. The rear fixing sleeve is then moved downwards until it is completely flush with the previous fixing sleeve, thus positioning the front and rear fixing sleeves on the outside of the pier body.

[0005] To address the aforementioned issues, existing patents have provided solutions, but these solutions suffer from limitations such as the inability to protect the ends of the flow deflector and the inability to quickly replace it. Existing flow deflectors are also susceptible to damage from impacts by debris on the river surface, making them difficult to replace, and they cannot be adjusted to accommodate water flow.

[0006] To address this, a guiding structure for handling water backlog at the piers of skew bridges is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a guiding structure for water backlog treatment of skew bridge piers, which can solve the problems of existing guiding structures for water backlog treatment of skew bridge piers, such as the inability to protect the end of the guide shield and the difficulty in quick replacement, the easy damage of existing guide shields to debris on the river surface leading to difficulty in replacement, and the inability of existing guide shields to adjust the angle to adapt to water flow.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 7 This utility model provides a technical solution:

[0032] A guiding structure for water backlog treatment of skew bridge piers includes a pier body 1, two mounting covers 2 fixedly connected to the side wall of the pier body 1, a support plate 3 provided on the side wall of the mounting cover 2, support plates 4 provided on both sides of the support plate 3, a flow guide hood 5 provided on the side wall of multiple support plates 4, a protective mechanism 6 provided at one end of the flow guide hood 5, an adjustment mechanism 7 for adjusting the angle of the flow guide hood 5 provided between the mounting cover 2 and the support plate 4, and a connecting component 8 provided between two flow guide hoods 5.

[0033] The protective mechanism 6 includes a mounting head 61 located at one end of the deflector 5. A T-shaped groove 62 is provided on the side wall of the mounting head 61. A T-shaped strip 63 is movably arranged inside the T-shaped groove 62. A protective strip 64 is fixedly connected to the side wall of the T-shaped strip 63. The end of the protective strip 64 is umbrella-shaped. The protective strip 64 is connected to the mounting head 61 by a fixing bolt 65.

[0034] Specifically, such as Figure 3As shown, the connecting assembly 8 includes two connecting seats 81 disposed on the top of the top plate 721. A connecting bolt 82 is disposed in the middle of the connecting seat 81. A locking groove 83 is disposed at the connection of the two flow guides 5. A locking plate 84 is disposed inside the two locking grooves 83.

[0035] Specifically, such as Figure 3 As shown, support strips 9 are provided on both sides of the protective strip 64, and the support strips 9 are engaged with the mounting head 61.

[0036] Specifically, such as Figure 3 As shown, mounting grooves 10 are provided on both sides of the protective strip 64, and reflective strips 11 are provided inside the mounting grooves 10.

[0037] Specifically, such as Figure 4 As shown, the two mounting covers 2 are bolted together, and the inner wall of the mounting cover 2 is provided with anti-slip pads 12, and the bottom of the mounting cover 2 is provided with multiple ground nails 13.

[0038] In use, a cover 2 is fixedly installed on the side wall of the pier body 1. The cover 2 is connected to the guide cover 5 through the support plate 3 and the support plate 4. When water flows through the pier body 1, the guide cover 5 can guide the water flow, change the direction of the water flow, and reduce the direct impact of the water flow around the pier body 1 on the pier body 1 and the backwater phenomenon. The installation head 61 of the protective mechanism 6 is set at one end of the guide cover 5. The T-shaped strip 63 is movably set in the T-shaped groove 62 of the installation head 61. The protective strip 64 is fixed on the T-shaped strip 63. The protective strip 64 is connected to the installation head 61 by the fixing bolt 65 to realize the quick installation of the protective strip 64. The protective strip 64 can prevent debris in the water flow from directly impacting the guide cover 5 and extend the service life of the guide cover 5. The umbrella-shaped setting at the end of the protective strip 64 can expand the protection range. The support strips 9 on both sides are engaged with the installation head 61 to enhance the stability of the protective strip 64. In the connecting assembly 8, the top plate 721 of the two guide covers 5 A connecting seat 81 is provided on the upper part, and two connecting seats 81 are connected together by connecting bolts 82. At the same time, a locking plate 84 is provided in the locking groove 83 at the connection of the two guide shields 5 to further enhance the stability of the connection between the two guide shields 5. In this way, through the setting of the protective mechanism 6, the guide shield 5 can effectively guide the water flow, reduce the direct impact of the water flow around the pier 1 on the pier, reduce the backwater height, improve the flood discharge capacity of the bridge, and ensure the safety of the bridge. The setting of the protective strip 64 can prevent debris in the water flow from directly hitting the guide shield 5 and extend the service life of the guide shield 5. The umbrella-shaped setting at the end of the protective strip 64 expands the protection range. The quick disassembly and assembly structure between the protective strip 64 and the mounting cover 2 facilitates the replacement and maintenance of the protective strip 64. The support strip 9 and the mounting head 61 are engaged to enhance stability, and reflective strips 11 are set in the mounting grooves 10 on both sides of the protective strip 64 to improve nighttime visibility and ensure the safety of the bridge and passing ships.

[0039] Specifically, such as Figure 5 As shown, the adjustment mechanism 7 includes a driving hydraulic rod 71 disposed on the side wall of the mounting cover 2. The end of the driving hydraulic rod 71 is hinged to the mounting cover 2, and the output end of the driving hydraulic rod 71 is hinged to the support plate 4. A positioning component 72 is disposed between the mounting cover 2 and the support plate 3 on the other side.

[0040] Specifically, such as Figure 7 As shown, the positioning component 72 includes a top plate 721 disposed on the top of the flow guide shroud 5. A positioning hydraulic push rod 722 is disposed in the middle of the top plate 721. Multiple positioning holes 723 are opened on the side wall of the support plate 3. The output end of the positioning hydraulic push rod 722 is adapted to the positioning hole 723.

[0041] Specifically, such as Figure 7 As shown, the top of the positioning hole 723 is flared, and the output end of the positioning hydraulic push rod 722 is arc-shaped.

[0042] In use, one end of the driving hydraulic rod 71 in the adjusting mechanism 7 is hinged to the installation device, and the other end is hinged to the support plate 4. The extension and retraction of the driving hydraulic rod 71 drives the support plate 4 to rotate, thereby changing the angle of the guide shield 5 to adapt to different water flow directions and operating conditions. This process is achieved by the two support plates 4 clamping the support plate 3. The support plates 4 and the support plate 3 are movably connected, providing stable support for the rotation of the guide shield 5. In the positioning assembly 72, the positioning hydraulic push rod 722 is set on the top plate 7 at the top of the guide shield 5. On the support plate 3, multiple positioning holes 723 are opened on the side wall. When the angle of the guide shield 5 is adjusted to the correct position, the output end of the positioning hydraulic push rod 722 extends into the corresponding positioning hole 723 to fix the angle of the guide shield 5. Thus, through the setting of the adjustment mechanism 7, the angle of the guide shield 5 can be flexibly adjusted according to the actual water flow conditions. Through the cooperation of the driving hydraulic rod 71 and the positioning hydraulic push rod 722, the angle of the guide shield 5 can be accurately controlled and fixed, which enhances the adaptability of the guiding structure to different water flow conditions.

[0043] By adopting the above technical solution, the problems of the existing guide structure for water treatment of skew bridge piers being unable to protect the end of the guide shield 5 and being unable to be quickly replaced, the existing guide shield 5 being easily damaged by debris on the river surface making it difficult to replace, and the existing guide shield 5 being unable to adapt to the water flow for angle adjustment are solved.

[0044] Working principle: In use, the two mounting covers 2 are bolted together for easy installation and disassembly. Anti-slip pads 12 are installed on the inner wall of the mounting cover 2 to enhance the stability of the connection with the pier body 1. Multiple ground nails 13 are installed at the bottom to further secure the mounting cover 2 and prevent displacement under water flow. Connecting seats 81 are installed on the top plates 721 of the two guide covers 5, and the two connecting seats 81 are connected together by connecting bolts 82. A locking plate 84 is installed in the locking groove 83 at the connection point of the two guide covers 5 to further enhance the stability of the connection. The mounting covers 2 are fixed to the side wall of the pier body 1, and the mounting covers 2 are connected to the guide covers 5 via support plates 3 and 4. When water flows through the pier 1, the guide shield 5 can guide the water flow, change the direction of the water flow, and reduce the direct impact of the water flow around the pier 1 on the pier 1 and the backwater phenomenon. The protective strip 64 is fixed on the T-shaped strip 63 and connected to the installation head 61 by the fixing bolt 65 to realize the quick installation of the protective strip 64. The protective strip 64 can prevent debris in the water flow from directly hitting the guide shield 5. By driving the extension and retraction of the hydraulic rod 71, the support plate 4 is driven to rotate, thereby changing the angle of the guide shield 5 to adapt to different water flow directions and working conditions. When the angle of the guide shield 5 is adjusted to the right position, the output end of the positioning hydraulic push rod 722 extends into the corresponding positioning hole 723.
