Description

Technical Field

[0001] This utility model relates to the field of steel cylinder concrete pipe technology, specifically a double rubber ring prestressed steel cylinder concrete pipe. Background Technology

[0002] Steel cylinder concrete pipe (PCCP) is a composite pressure pipe. It is made of thin steel cylinders rolled into sections in the factory using a plate rolling machine. These sections serve as the load-bearing layer of the steel cylinder concrete pipe. Concrete or high-density cement mortar is then poured into the inside and outside of the steel cylinder. Steel cylinder concrete pipe combines the advantages of steel and concrete, and has high compressive strength, impermeability, good corrosion resistance and durability. It is widely used in large-scale water transmission projects, urban water supply networks and other fields, and is especially suitable for occasions that bear high internal pressure and external loads.

[0003] Double-rubber-ring prestressed steel cylinder concrete pipe is an improved pressure pipeline developed from steel cylinder concrete pipe. It uses two layers of rubber sealing rings instead of the traditional single-layer seal and applies prestress to enhance structural performance. Its manufacturing process is usually as follows: first, thin steel plates are rolled into steel cylinders, and grooves are reserved on the inner side of the steel cylinder. Then, a concrete layer is poured. After the concrete reaches a certain strength, prestress is applied to the concrete by winding prestressed steel wires or steel strips. Finally, double rubber sealing rings are installed on the outer side of the steel cylinder and at the joints. This type of pipeline has higher sealing performance, impermeability and structural strength, and can effectively resist internal water pressure, external loads and uneven foundation settlement. It is particularly suitable for high-pressure, large-diameter, long-distance water transmission projects and areas with complex geological conditions.

[0004] However, in existing double-rubber-ring prestressed steel cylinder concrete pipes, the traditional fixed connection method makes disassembling the rubber rings very difficult, requiring damage to the pipe body or the use of special tools, which is time-consuming and labor-intensive, greatly reducing maintenance efficiency. Furthermore, it is impossible to adjust the distance between the two rubber rings according to actual needs, making it difficult to adapt to different installation environments or pipe deformation. At the same time, it is impossible to adjust the position of a single rubber ring, limiting the flexibility of adjustment and thus failing to achieve the best sealing effect. To address the above problems, a double-rubber-ring prestressed steel cylinder concrete pipe is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a double-rubber-ring prestressed steel cylinder concrete pipe, which solves the problems in the prior art of not being able to quickly and independently disassemble the two rubber rings and not being able to adjust the position of the two rubber rings.

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.

[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0034] Reference Figure 1 and Figure 4 This utility model discloses a double-rubber-ring prestressed steel cylinder concrete pipe, comprising a pipe body 1, one end of which is provided with a flared end 2, through which necessary structures and components can be connected and fixed. One end of a connecting rod 5 is provided with a rubber ring 9, which is fixedly connected to a fixing rod 3. The rubber ring 9 ensures a seal between the interface 18 and the flared end 2. An adjustment component is provided inside the pipe body 1, and a steel cylinder 10 is provided inside the pipe body 1, which is connected and fixedly connected to a sliding rod 12. The steel cylinder 10 can withstand circumferential prestress, improving the impermeability and structural safety of the pipeline. A steel wire 11 is provided on the outer wall of the steel cylinder 10, which can be circumferentially wound around the outside of the steel cylinder 10. Prestress is generated by tensioning, so that the concrete layer is under pressure, improving the crack resistance and load-bearing capacity of the pipeline. The other end of the pipe body 1 is provided with an interface 18, which contacts the rubber ring 9. The interface 18 allows the pipe body 1 to be linked with the flared end 2 of another pipe body, thereby forming the required transportation route.

[0035] Reference Figure 2 and Figure 3The bottom of the inner wall of the flared opening 2 is fixedly connected with evenly distributed fixing rods 3. The fixed rods 3 can support the required connecting rods 5. The outer wall of the fixing rods 3 is provided with evenly distributed slots 4. The slots 4 allow the connecting rods 5 to be fixed in a designated position. The inner wall of the fixing rods 3 is slidably connected with the connecting rods 5. The connected rods 5 can support the required first springs 6. One end of the connecting rods 5 is passed through and fixedly connected to the first springs 6. The first springs 6 can drive the limiting discs 7 to slide. The other end of the first springs 6 is fixedly connected to the limiting discs 7, and the limiting discs 7 are slidably connected to the connecting rods 5. The limiting discs 7 allow the supporting rods 8 to slide on the connecting rods 5. One end of the limiting discs 7 is fixedly connected to the supporting rods 8, and the supporting rods 8 are slidably connected to the connecting rods 5. The supporting rods 8 are in contact with the slots 4. The supporting rods 8 allow the connecting rods 5 to be fixedly limited on the fixing rods 3.

[0036] Reference Figure 4 and Figure 5 The adjustment assembly includes a slide rod 12, which is connected to the inner wall of the tube body 1. A second spring 13 is connected to the top of the slide rod 12 and fixedly. A limit rod 14 is fixedly connected to the other end of the second spring 13 and is connected to the slide rod 12. The limit rod 14 is connected to the slide rod 12 and is slidably connected. A main plate 15 is provided at one end of the limit rod 14. An extension plate 16 is connected to adjacent main plates 15 and is slidably connected to each other. Sealing gaskets 17 are provided at both ends of the inner walls of the extension plate 16 and the main plate 15 and are fixedly connected to the tube body 1. By sliding the main plate 15, the extension plate 16 slides within the main plate 15, thereby allowing the limit rod 14 to slide within the slide rod 12, which in turn compresses the second spring 13. This absorbs and buffers a certain amount of vibration, improving the shock resistance of the tube body 1.

[0037] Working principle: By allowing the bearing rod 8 to slide into the connecting rod 5, the limiting disc 7 slides within the connecting rod 5, thereby compressing the first spring 6. This causes the connecting rod 5 to slide into the fixing rod 3, and then slide to the designated position. Subsequently, the rebound of the first spring 6 causes the limiting disc 7 to reset, allowing the bearing rod 8 to slide out of the connecting rod 5 and into the corresponding slot 4. This fixes the required rubber ring 9 in the designated position, ensuring the required sealing performance. When the tube 1 begins to transport liquid, the liquid is transported through the sealing gasket 17 to the area between the main board 15 and the extension board 16. When the water pressure increases, the extension plate 16 slides a certain distance between the main plate 15 and the main plate 15, causing the main plate 15 to slide a certain distance downward against the limit rod 14, thus allowing the limit rod 14 to slide within the slide rod 12, thereby compressing the second spring 13. Subsequently, through the rebound of the second spring 13, the sliding distance of the main plate 15 is limited, but at the same time, the main plate 15 and the extension plate 16 have a certain expansion capacity, thereby improving the protection of the steel cylinder 10. Furthermore, one end of the sealing gasket 17 contacts and seals the main plate 15 and the extension plate 16, thereby ensuring good sealing performance of the entire pipe body 1 during transportation.
