Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline connection technology, and in particular to a transition pipeline connection device and pipeline system. Background Technology
[0002] Pipeline transition issues are prevalent in the construction of underground oil tank supply projects and other projects involving pipeline systems. In underground oil tank supply projects, to promptly monitor equipment leakage risks, a liquid collection area is typically set up in the center of the tank, connected to the outside of the load-bearing area via a diversion pipe, thus enabling rapid monitoring and early warning of leaked media. However, the existence of vertical and horizontal pipeline transition structures in the diversion pipe system brings many problems. Due to the significant differences in the stress conditions borne by vertical and horizontal pipelines, local stress concentration is easily generated at the connection points. This local stress concentration can further lead to pressure damage at the pipeline connection, resulting in leakage of stored oil. Moreover, because the monitoring system cannot quickly capture leakage signals, it is highly likely to induce serious safety accidents and cause economic losses. In water supply and drainage engineering sludge drying plant pipeline systems and other projects, problems such as pipeline leakage and structural instability due to unreasonable transition structures are also common at load-bearing pipeline transition connection points, affecting the normal operation and service life of the project.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a connecting pipe device, which is installed in the lower part of the gravel collection area of the liquid collection zone. Its starting end is connected to the geomembrane, passes downward through the buffer layer, and connects to the downstream pipe inside the waterproof base plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0017] The purpose of this utility model is to provide a connecting device and piping system for transition pipes to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively prevents leakage of transition pipes, and extends the service life of the entire transition pipe system.
[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] This utility model provides a connecting pipe device 1, which is installed at the lower part of the gravel collection area 2 in the liquid collection area. Its starting end is connected to the impermeable membrane 3, passes downward through the buffer layer 4, and connects to the downstream pipe 6 inside the waterproof base plate 5; Figures 1-4 As shown, it includes: an inner flexible hose body 11 and an outer protective tube 12. The inner flexible hose body 11 is an integral structure made of flexible material. The inner flexible hose body 11 includes a corrugated hose 111, a peripheral connecting plate 112 disposed at the top of the corrugated hose 111, a perforated grid 113 disposed inside or at the top of the corrugated hose 111, and a lower connecting area 114 disposed at the bottom of the corrugated hose 111. The outer protective tube 12 is an integral I-shaped structure made of rigid material. The outer protective tube 12 is sleeved on the inner flexible hose body 111. Outside the inner hose body 11, the outer protective tube 12 includes an upper connecting plate 121, a lower support plate 122, a protective wall 123 connecting the upper connecting plate 121 and the lower support plate 122, and a downstream pipe perforation 124 opened on the lower side of the protective wall 123 for the downstream pipe 6 to pass through. The outer connecting plate 112, the upper connecting plate 121, and the geomembrane 3 are fixedly connected by welding. The lower support plate 122 is embedded in the waterproof base plate 5. The lower connecting area 114 is connected to the downstream pipe 6 by heat fusion. The integrated structure made of flexible material gives the inner hose body 11 good flexibility and overall stability. The corrugated hose 111 increases its bending and pressure resistance, and can adapt to a certain degree of deformation without affecting liquid delivery. The outer connecting plate 112 facilitates connection with other components. The perforated grid 113 can perform preliminary filtration and uniform distribution of the liquid, improving the stability and uniformity of liquid delivery. The lower connecting area 114 enables communication with the downstream pipe 6. The rigid, integrated I-beam structure provides excellent structural strength and stability. It is fitted over the inner hose body for protection. The upper connecting plate 121 connects to the geomembrane 3, ensuring a tight seal; the lower support plate 122 is embedded in the waterproof base plate 5 for stable support; the protective wall 123 forms a protective barrier for the inner hose body 11; the downstream pipe perforation 124 ensures smooth connection of the downstream pipe 6, enhancing the overall versatility and stability of the device. Welded connections ensure a strong and airtight connection, preventing liquid leakage. The lower support plate 122 embedded in the waterproof base plate 5 increases the stability of the device and effectively distributes and withstands the pressure of the pipeline system. Hot-melt connections ensure a tight and well-sealed connection between the lower connection area 114 and the downstream pipe 6, further improving the reliability of the entire device during liquid transport.
[0020] In a preferred embodiment, the inner hose 11 is made of high-density polyethylene, which has good corrosion resistance, flexibility, and impact resistance. This allows the inner hose 11 to maintain stable performance in complex liquid transport environments, making it less susceptible to corrosion and damage, thus extending the service life of the device.
[0021] In a preferred embodiment, the outer protective tube 12 is made of stainless steel, which has high strength, corrosion resistance, and oxidation resistance. This provides strong structural support for the device, preventing damage to internal components from external factors, while maintaining good performance in different environments, ensuring long-term stable operation of the device.
[0022] In a preferred embodiment, the inner diameter of the inner hose 11 is the same as the inner diameter of the downstream pipe 6. Having the same inner diameter reduces pressure loss and flow rate changes caused by pipe diameter changes when the liquid flows from the inner hose 11 into the downstream pipe 6, ensuring the stability and continuity of liquid transportation and improving the transportation efficiency of the entire pipeline system.
[0023] In a preferred embodiment, the inner diameter of the protective wall 123 is 1-2 cm larger than the outer diameter of the corrugated hose 111, so as to form an annular buffer gap between the corrugated hose 111 and the protective wall 123. This annular buffer gap provides a certain amount of expansion and contraction space for the inner hose body 11, which can buffer the stress caused by factors such as temperature changes and pipeline vibration, prevent the corrugated hose 111 from being damaged by compression, and enhance the adaptability and stability of the device.
[0024] In a preferred embodiment, the diameter of the downstream pipe perforation 124 is equal to the outer diameter of the downstream pipe 6. The equal diameter ensures that the downstream pipe 6 can accurately pass through the perforation to achieve connection, and effectively avoids leakage after connection, ensuring the sealing and integrity of the entire pipeline system and making the liquid transportation process more reliable.
[0025] In a preferred embodiment, the welding overlap length between the outer connecting plate 112, the upper connecting plate 121, and the geomembrane 3 is not less than 150mm. A sufficiently long welding overlap length can significantly improve the strength and sealing of the connection, reduce the risk of cracks and leakage at the connection, and ensure the stability of the structure and function of the device during long-term operation.
[0026] In a preferred embodiment, the porosity of the perforated grid 113 is 30%-50%. This porosity range ensures that the perforated grid 113 has a good filtration and uniform flow distribution effect on the liquid, removing impurities from the liquid, while preventing the liquid from being blocked due to excessively small porosity, thus affecting the liquid transport efficiency.
[0027] In a preferred embodiment, the inner diameter of the inner hose 11 and the downstream pipe 6 are both 100 mm, the diameter of the downstream pipe perforation 124 and the outer diameter of the downstream pipe 6 are both 102 mm, the outer diameter of the inner hose 11 is 104 mm, and the inner diameter of the protective wall 123 is 106 mm.
[0028] This utility model also provides a pipeline system, including a gravel collection area 2, a buffer layer 4, a waterproof base plate 5, a geomembrane 3, and a downstream pipe 6. The pipeline system is characterized by using a transfer pipe connection device 1 as described above to achieve a transfer connection between the geomembrane 3 and the downstream pipe 6. By employing the transfer pipe connection device 1, this pipeline system achieves effective connection and stable operation between various components. It can promptly monitor equipment leakage risks, effectively prevent pipeline leakage, enhance structural stability, ensure the normal operation of the entire pipeline system, improve the safety and reliability of the project, and is applicable to various similar engineering scenarios.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
