Description

Technical Field

[0001] This utility model relates to the field of drainage pipe reinforcement technology, specifically a drainage pipe reinforcement structure for water conservancy and hydropower projects. Background Technology

[0002] Water conservancy and hydropower projects are crucial infrastructure supporting national economic development, with core functions encompassing multiple dimensions such as water resource allocation, flood control and disaster reduction, power supply, and ecological protection. Among these, the drainage system, acting as the "arteries" of the project, undertakes critical tasks such as draining accumulated water, balancing water levels, and preventing structural erosion. Especially in the main structures of bridges and dams, the stability of the drainage pipes directly affects the overall safety and durability of the project. In bridge engineering, piers, as the core load-bearing components supporting the superstructure, often require various drainage pipes (such as rainwater pipes and maintenance drainage pipes) to be installed on their outer walls. Therefore, the drainage pipes are typically reinforced and connected to the piers using fasteners.

[0003] Existing reinforcement components typically include U-shaped clamps, which are rigidly connected to the concrete outer wall of the bridge pier by expansion bolts. The inner side of the clamp is equipped with rubber anti-slip pads to fix the water pipe to the bridge pier.

[0004] However, the clamps are only connected to the piers by bolts. Vibrations generated during drainage can cause the clamps to loosen, resulting in inconvenience. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drainage pipe reinforcement structure for water conservancy and hydropower projects, which makes the drainage pipe more stable after being connected to the bridge pier.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage pipe reinforcement structure for water conservancy and hydropower projects, comprising an arc-shaped clamp located on one side of the pipe body, side blocks fixedly connected to both sides of the arc-shaped clamp, and an L-shaped plate connected to one side of each of the two side blocks. The L-shaped plate is composed of a horizontal plate and a vertical plate. The side blocks are fixedly connected to the horizontal plate. A second expansion bolt connected to the mounting surface is threaded onto the vertical plate of each of the two L-shaped plates. An arc-shaped plate is connected between the two horizontal plates. The pipe body is located between the arc-shaped plate and the arc-shaped clamp. Outer plates are fixedly connected to both sides of the outer wall of the arc-shaped plate. A snap-fit ​​structure connects the outer plate to the horizontal plate.

[0007] Furthermore, the snap-fit ​​structure includes an insert plate, and both outer ends of the two horizontal plates are provided with sliding grooves. The outer plate is slidably connected within the sliding grooves. An insert plate for limiting the outer plate is inserted into the top surface of the horizontal plate. The insert plate passes through the horizontal plate and is slidably connected with the sliding groove. The side of the outer plate that slides with the insert plate is provided with a bevel.

[0008] Furthermore, two sets of limiting strips are fixedly connected to both sides of the outer wall of the insert plate, and the two sets of limiting strips are located on the upper and lower sides of the horizontal plate respectively.

[0009] Furthermore, the cross-section of the insert plate is T-shaped.

[0010] Furthermore, two symmetrically arranged connecting plates are fixedly connected between the vertical plates of the two L-shaped plates, and the two connecting plates are threaded with a first expansion bolt connected to the mounting surface.

[0011] Furthermore, a support plate is fixedly connected between the vertical plate and the horizontal plate.

[0012] Furthermore, a fixing sleeve is fixedly connected to the top surface of the horizontal plate of the L-shaped plate, a U-shaped insert is snapped into the lower end of the horizontal plate, and a coaxial rod threadedly connected to the bottom of the U-shaped insert is rotatably connected to the fixing sleeve.

[0013] Furthermore, the side blocks on both sides of the arc-shaped clamp are fixedly installed to the horizontal plate by fastening bolts.

[0014] Furthermore, anti-slip pads are fixedly connected to the side of the arc-shaped clamp and the arc-shaped plate closest to the pipe body.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses two L-shaped plates and connects the arc-shaped clamp and the arc-shaped plate to the L-shaped plates, so that the weight of the arc-shaped clamp, the arc-shaped plate and the pipe body can be distributed to the L-shaped plates on both sides, which makes the support effect better and the stability of the pipe body after installation better. The structure is simple, easy to operate and highly practical. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4 As shown, a drainage pipe reinforcement structure for a water conservancy and hydropower project includes an arc-shaped clamp 1 located on one side of the pipe body 2. Side blocks 3 are fixedly connected to both sides of the arc-shaped clamp 1. An L-shaped plate is connected to one side of each of the two side blocks 3. The L-shaped plate is composed of a horizontal plate 5 and a vertical plate 4. The side blocks 3 are fixedly connected to the horizontal plate 5. The vertical plate 4 on the two L-shaped plates is threaded with a second expansion bolt 16 connected to the mounting surface. An arc-shaped plate 7 is connected between the two horizontal plates 5. The pipe body 2 is located between the arc-shaped plate 7 and the arc-shaped clamp 1. An outer plate 8 is fixedly connected to both sides of the outer wall of the arc-shaped plate 7. A snap-fit ​​structure connects the outer plate 8 to the horizontal plate 5.

[0020] like Figures 1 to 4 As shown, when using the drainage pipe reinforcement structure of the water conservancy and hydropower project in this utility model, first install the two L-shaped plates in the first reinforcement structure at the highest point, so that the two L-shaped plates are installed with the installation surface through the second expansion bolt 16, so that the arc-shaped clamp 1 is just concentric with the central axis of the drain hole on the bridge (not shown in the figure). Then, place the pipe body 2 inside the arc-shaped clamp 1, and install and connect the top of the pipe body 2 with the drain hole. Then, install and connect the arc-shaped plate 7 with the two horizontal plates 5 through the snap-fit ​​structure, so that the arc-shaped plate 7 just abuts against the outer wall of the pipe body 2. At this time, the arc-shaped clamp 1 and the arc-shaped plate 7 just fix the pipe body 2.

[0021] By using two L-shaped plates, and installing and connecting the arc-shaped clamp 1 and arc-shaped plate 7 to the L-shaped plates, the weight of the arc-shaped clamp 1, arc-shaped plate 7, and pipe body 2 can be distributed to the L-shaped plates on both sides, resulting in good support and better stability of pipe body 2 after installation.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the snap-fit ​​structure includes an insert plate 9, and two horizontal plates 5 are provided with sliding grooves 10 at their outer ends. The outer plate 8 is slidably connected within the sliding grooves 10. An insert plate 9 for limiting the outer plate 8 is inserted into the top surface of the horizontal plate 5. The insert plate 9 passes through the horizontal plate 5 and is slidably connected with the sliding grooves 10. The side of the outer plate 8 that slides with the insert plate 9 is provided with a beveled edge 19.

[0023] Specifically, when the arc plate 7 needs to be installed, the outer plates 8 on both sides of the arc plate 7 can be slidably inserted into the grooves 10 on the horizontal plate 5. Then, the insert plate 9 is inserted into the horizontal plate 5. The insert plate 9 is lowered to push the inclined side 19 to move, so that the outer plate 8 drives the arc plate 7 closer to the tube body 2. As the insert plate 9 is lowered, the outer plate 8 and the arc plate 7 are pressed more tightly against the tube body 2, so that the tube body 2 is more securely fastened.

[0024] like Figure 3 and Figure 4 As shown, two sets of limiting strips 20 are fixedly connected to both sides of the outer wall of the insert plate 9, and the two sets of limiting strips 20 are located on the upper and lower surfaces of the horizontal plate 5, respectively. When the insert plate 9 is inserted, the limiting strips 20 serve to fix it on the upper and lower surfaces of the horizontal plate 5.

[0025] like Figure 4 As shown, the cross-section of the insert plate 9 is T-shaped. The T-shaped insert plate 9 allows for insertion operations.

[0026] like Figure 2 and Figure 3 As shown, two symmetrically arranged connecting plates 13 are fixedly connected between the vertical plates 4 of the two L-shaped plates. The two connecting plates 13 are threaded with first expansion bolts 14 that are connected to the mounting surface. The two L-shaped plates can be connected into one unit through the connecting plates 13, and the setting of the first expansion bolts 14 increases the overall stability.

[0027] like Figure 2 and Figure 3 As shown, a support plate 6 is fixedly connected between the vertical plate 4 and the horizontal plate 5. The support plate 6 facilitates the stable reinforcement of the support between the vertical plate 4 and the horizontal plate 5.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a fixing sleeve 12 is fixedly connected to the top surface of the horizontal plate 5 of the L-shaped plate, and a U-shaped plug 15 is snapped into the lower end of the horizontal plate 5. A coaxial rod 11 that is threadedly connected to the fixing sleeve 12 is rotatably connected to the bottom of the U-shaped plug 15.

[0029] Specifically, to ensure that the center lines of the arc-shaped clamps 1 on the two L-shaped plates remain concentric, the coaxial rod 11 can be threadedly connected to the fixing sleeve 12, and the U-shaped insert 15 can be connected to the bottom of the vertical plate 4 of the L-shaped plate. This ensures that the two adjacent L-shaped plates maintain a unified center line, facilitating the installation of the next section of pipe 2. In practical applications, two coaxial rods 11 can be set, one on each side of the L-shaped plate.

[0030] like Figure 2 and Figure 3As shown, the side blocks 3 on both sides of the arc-shaped clamp 1 are fixedly installed to the horizontal plate 5 by fastening bolts 17. This arrangement facilitates the disassembly and replacement of the side blocks 3 and the arc-shaped clamp 1.

[0031] like Figure 2 and Figure 3 As shown, anti-slip pads 18 are fixedly connected to the side of the arc-shaped clamp 1 and the arc-shaped plate 7 near the pipe body 2. The anti-slip pads 18 are provided to increase the friction when connected to the pipe body 2 and prevent pinching.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
