[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0036] See also Figure 1-6 , a tongue-and-groove reinforced concrete pipe flexible interface structure, comprising:
[0037] The upstream pipe 1 is a prefabricated reinforced concrete pipe, as a part of the pipeline, having a protruding insertion end 1a. The insertion end 1a includes a first hollow cylinder 11 and a second hollow cylinder 12, wherein the radius of the first hollow cylinder 11 is larger than that of the second hollow cylinder 12, forming a first step 4a.
[0038] The downstream pipe 2 is also a prefabricated reinforced concrete pipe, connected to the upstream pipe 1, and has a corresponding inserted mounting end 1b. The mounting end 1b includes a first notch 21 and a second notch 22, and the radius of the first notch 21 is larger than that of the second notch 22, forming a second step 4b. By having a protruding insertion end 1a on the upstream pipe 1, the downstream pipe 2 has a corresponding inserted mounting end 1b, and the insertion end 1a is inserted into the mounting end 1b.
[0039] Inserting the insertion end 1a into the installation end 1b can, firstly, enhance the stability of the pipeline connection, facilitate construction and installation, and improve installation efficiency; secondly, the stepped design makes it easier to align the upstream pipe 1 and the downstream pipe 2 during installation, improving construction efficiency; thirdly, the stepped connection increases the contact area between the upstream pipe 1 and the downstream pipe 2, improving the stability of the overall structure. Compared with the traditional flat interface, this design provides better connection stability and sealing, and simplifies the installation steps.
[0040] The sealing member 4 is used for sealing connection between the upstream pipe 1 and the downstream pipe 2, and is sleeved on the first step 4a. When the insertion end 1a is inserted into the installation end 1b, the first step 4a and the second step 4b jointly clamp and fix the sealing member 4. Further, the sealing member 4 is annular, and the annular sealing member 4 can fit tightly between the upstream pipe 1 and the downstream pipe 2.
[0041] In this way, firstly, the sealing performance between the upstream pipe 1 and the downstream pipe 2 is ensured, and the stepped design increases the contact area of the seal 4 and improves the reliability of the seal; secondly, the design of the first step 4a and the second step 4b enables the seal 4 to be effectively clamped and fixed, thereby enhancing the sealing performance between the upstream pipe 1 and the downstream pipe 2; the innovative stepped clamping design effectively solves the leakage problem existing in the traditional sealing method and achieves an efficient sealing effect.
[0042] The water stop assembly includes a first water stop plate 31 fixed to the upstream pipe 1 and a second water stop plate 32 fixed to the downstream pipe 2. The first water stop plate 31 is hollow, and has a groove-shaped concave ring 311 on the side adjacent to the second water stop plate 32. The groove wall of the concave ring 311 is bent outward to form a smooth arc transition, and a thin shell design is adopted. The second water stop plate 32 is also hollow, and has an open opening 322 on the side corresponding to the concave ring 311, and an annular retaining ring 321 is arranged on the inner wall of the opening 322. When the concave ring 311 is inserted into the opening 322, the retaining ring 321 is embedded in the concave ring 311, so as to realize a firm connection between the first water stop plate 31 and the second water stop plate 32. The first water stop plate 31 and the second water stop plate 32 are fixed by welding, and the welding position is at the annular square groove (edge notch 20) reserved on the outer side of the downstream pipe 2. The design of the concave ring 311 and the snap ring 321 makes the water-stop assembly more stable and less likely to fall off; the innovative interlocking design of the concave ring 311 and the snap ring 321 simplifies the installation process of the water-stop assembly, improves its stability, reduces the impact of water flow on the water-stop assembly, and extends its service life.
[0043] Asphalt caulking glue is used to fill the outer surface gap between the upstream pipe 1 and the downstream pipe 2 to enhance the sealing and stability of the interface; it further enhances the sealing performance of the pipeline to prevent the intrusion of external moisture or impurities. The asphalt caulking glue has good elasticity and corrosion resistance and can adapt to slight deformations of the pipeline; combined with the elastic sealing characteristics of the asphalt caulking glue, it improves the adaptability and durability of the pipeline interface, and an additional sealing effect can be achieved through a simple filling operation.
[0044] As a further improvement of the present invention, the concave ring 311 of the first water stop plate 31 adopts a thin shell design. The diameter of the concave ring 311 is larger than the diameter of the straight portion 312, but the groove depth of the concave ring 311 does not exceed the edge of the straight portion 312. This design not only ensures the strength and toughness of the concave ring 311, but also avoids excessive deformation of the concave ring 311 during welding.
[0045] As a further improvement of the present invention, the retaining ring 321 of the second water stop plate 32 is arranged at an angle to form a first end foot 321a and a second end foot 321b in the opening 322. The first end foot 321a and the second end foot 321b are respectively inserted into the left and right sides of the groove wall of the concave ring 311. Such a design increases the contact area and friction between the concave ring 311 and the retaining ring 321, thereby improving the fixing effect of the water stop assembly.
[0046] As a further innovation of the present invention, an annular square groove is reserved in the inner layer of the upstream pipe 1 to form an inner edge notch 10, an annular base 61 is welded on the inner edge notch 10, and a plurality of elastic sheets 62 are welded on the base 61. The elastic sheet 62 is a corrugated design and can be inserted into the gap between the second hollow cylinder 12 and the second notch 22. Such a design not only increases the connection strength between the upstream pipe 1 and the downstream pipe 2, but also can play a role in buffering and shock absorption when the pipeline is subjected to external force, further improving the stability of the pipeline. When the insertion end 1a of the upstream pipe 1 is inserted into the installation end 1b of the downstream pipe 2, the elastic sheet 62 is inserted into the gap between the second hollow cylinder 12 and the second notch 22, providing additional sealing and fixing effects. The design of the elastic sheet 62 enables the pipeline to produce a certain elastic deformation when subjected to external force, absorb and disperse the impact force; increases the flexibility of the pipeline interface, improves the seismic performance of the pipeline, and enables the pipeline to maintain a certain deformation capacity when subjected to external force, thereby reducing damage to the pipeline. The innovative design of the elastic sheet 62 combines the flexible characteristics of the corrugated structure, improves the seismic resistance and deformation capacity of the pipeline, and achieves an efficient flexible connection effect through a simple structural design. In addition, the elastic sheet 62 can fit tightly between the upstream and downstream pipes 2, further enhancing the sealing performance.
[0047] A management system for tongue-and-groove reinforced concrete pipes comprises mutually connected tongue-and-groove reinforced concrete pipes, and a plurality of patch-type passive RFID pressure sensor chips D arranged between the tongue-and-groove reinforced concrete pipes, an RFID reader, and a management platform; the passive RFID pressure sensor chip D is used to monitor the pressure of the pipe; through variable periodic inspections, the RFID reader is used to read data from each passive RFID pressure sensor chip D, and historical data is compiled, and the inspection cycle is adjusted based on the historical data.
[0048] The patch-type passive RFID pressure sensor chip D is a prior art and can be purchased on the market. In this embodiment, the EPC Gen 2 ultra-high frequency (UHF) RFID chip Magnus S is used; wherein the RFID pressure sensor chip D can be arranged between the water-stop assembly and the seal 4 to detect pressure changes, leakage risks and other abnormal conditions in the pipeline. Specifically, the patch-type passive RFID pressure sensor chip D of each node (the upstream pipe 1 and the downstream pipe 2 are connected to form a node) can be read by regular inspections to obtain information of each node. In addition, when the historical data of the pressure changes of each node are collected, the frequency of inspections and data collection can be increased for each node with a large pressure change. On the contrary, the frequency of inspections and data collection can be reduced for each node with a small pressure change.
[0049] As a further improvement, the data can be further sorted and analyzed. Specifically, the pressure change of the node can be used to roughly determine whether it is a leakage risk or a pipeline stress damage risk. For example, when the pressure shows a trend of slow decline or rise, it can be attributed to leakage; if the pressure shows a sudden and sharp rise, it can be attributed to pipeline stress damage. Furthermore, if it is attributed to pipeline stress damage, it can be further confirmed whether it is a single node or a continuous node. If it is a continuous large-scale node, further warning can be issued, because this may be caused by local geological problems.
[0050] The management platform has a data visualization function, which can intuitively display information such as pipeline pressure changes, leakage risks and stress damage risks in the form of charts, maps, etc., to facilitate management personnel to conduct further analysis and decision-making.
[0051] As a further improvement, drones were introduced and equipped with RFID readers, which were used for periodic inspections to improve inspection efficiency and safety.
[0052] A construction method for a tongue-and-groove reinforced concrete pipe flexible interface structure; comprising the following steps:
[0053] Step 1: Pretreatment of accessories: Weld the first water stop sheet 31 and the second water stop sheet 32 to the outermost steel bars of the upstream pipe 1 and the downstream pipe 2 respectively, and weld the base 61 with the elastic sheet 62 to the inner edge notch 10. Fixing the water stop copper sheet and the elastic sheet 62 by welding has higher stability and durability than traditional connection methods (such as bolt connection, gluing, etc.); the combined design of the base 61 and the elastic sheet 62 increases the flexibility and sealing of the pipeline interface, and welding can be performed before the pipeline is installed, without the need for additional construction on site, which reflects the innovation in structural design.
[0054] Step 2: Pre-buried upstream pipe 1 and downstream pipe 2: After the concrete age is reached, use a crane to lift the downstream pipe 2 to the designed position of the pipeline. Pre-buried pipelines ensure the stability and accuracy of the pipelines during installation and reduce the adjustment work in subsequent construction; although the steps of pre-buried pipelines are common, combined with the subsequent flexible interface structure design, the entire pipeline system is more stable and reliable, reflecting the overall consideration of the construction process.
[0055] Step 3: Install the upstream pipe 1 and the downstream pipe 2: Put the seal 4 on the first step 4a, use a crane to lower the upstream pipe 1 into the excavated pipeline groove, move the upstream pipe 1 so that the insertion end 1a is inserted into the installation end 1b, and at the same time, the elastic sheet 62 is inserted into the gap. The design of the stepped clamping and fixing seal 4 improves the stability and sealing effect of the seal 4, and has higher waterproof performance than the traditional flat sealing method; the addition of the elastic sheet 62 not only increases the flexibility of the pipeline interface, but also improves its ability to adapt to deformation, reflecting the innovation and optimization in structural design.
[0056] Step 4: Sealing and fixing: After the insertion end 1a is fully inserted into the installation end 1b, the first water stop sheet 31 and the second water stop sheet 32 are welded and fixed at the edge notch 20. The snap-fit design of the concave ring 311 and the opening 322, and the fixing effect of the clamping ring 321 on the concave ring 311, ensure the tight connection between the water stop copper sheets and improve the waterproof performance of the pipeline. The snap-fit design of the concave ring 311 and the opening 322 and the fixing effect of the clamping ring 321 reflect the innovation in the connection method of the water stop assembly and improve the stability and sealing of the connection; and the welding and fixing at the edge notch 20 further enhances the stability of the water stop assembly. This step simplifies the construction steps and ensures the firmness of the water stop assembly.
[0057] Step 5: Filling and fixing: Fill the edge gap 20 with asphalt caulking glue to enhance the sealing and stability of the interface. The sealing and waterproof performance of the pipeline interface is further enhanced; in addition, the asphalt caulking glue also has a certain elasticity, which can adapt to the slight deformation of the pipeline and maintain the sealing of the interface. The use of asphalt caulking glue for filling and fixing not only improves the sealing of the pipeline interface, but also increases its ability to adapt to deformation, reflecting innovation in material selection.
