[0024] The cross section of the sealing ring is a "9"-shaped structure, the upper part of the "9"-shaped structure is a hollow part 3-1, which is embedded in the sealing ring groove, and the lower part of the "9"-shaped structure is a tail 3-2, which is arranged close to the edge of the sealing ring groove, so as to achieve a tight embedded seal. In order to further improve the elasticity and sealing performance of the sealing ring, the middle part of the sealing ring is filled with an expansion liquid 3-3;

[0025] In order to facilitate the socket-and-spigot installation between the unit row pipes, both ends of the row pipe body 1 are fixedly connected with connectors, and the connectors can be mounting ear 9 structures or plug-in structures;

[0026] Each pair of mounting ears or plug-in structures are connected by connecting reinforcing ribs, which greatly improves the installation strength of the connector and also improves the hoisting strength of the pipe body during hoisting and transportation;

[0027] The mounting ear structure needs to be connected by bolt rods after the actual socket connection;

[0028] The plug-in structure includes a mounting block 16 and a connecting seat 15, one side of the row pipe body 1 is fixedly connected to the connecting seat 15, one side of the mounting block 16 is fixedly connected to an inserting block 17, the outer wall of the inserting block 17 is slidably connected to the inside of the connecting seat 15, the inside of the inserting block 17 is slidably connected to a symmetrically arranged limit plate 18, one side of the limit plate 18 is fixedly connected to a clamping block 19, a telescopic rod 20 is arranged inside the inserting block 17, the outer wall of the telescopic rod 20 is sleeved with a third spring 21, both ends of the telescopic rod 20 and the third spring 21 are fixedly connected between the limit plate 18, the inside of the connecting seat 15 is slidably connected to a limit plate 22, the top of the limit plate 22 is fixedly connected to a top column 23, the bottom of the limit plate 22 is fixedly connected to a top block 24, the outer wall of the top block 24 is sleeved with a first spring 8, one end of the first spring 8 is fixedly connected to the bottom of the limit plate 22, and the other end of the first spring 8 is fixedly connected to the inside of the connecting seat 15;

[0029] In the specific implementation of the utility model, a circular groove is also provided on the end surface of the tube body at the outer extension of the sleeve, for embedding the second sealing ring;

[0030] In order to increase detection and other functions through the underground pipe arrangement, the utility model also has a reserved hole 5 in the pipe arrangement body, and a plastic pipe is coaxially embedded in the hole to facilitate the installation of communication facilities, etc.

[0031] In the specific implementation of the utility model, a plurality of reinforcing ring ribs (not shown in the figure) are evenly and spacedly arranged in the row pipe body, and the row pipe body is a concrete cuboid;

[0032] Specifically, first, the protrusion 4 on one side of the row pipe body 1 is embedded in the socket 2 of another row pipe body 1. The design of the protrusion 4 often takes into account the precise match with the socket 2. Through precise size and shape, the two can be seamlessly connected, effectively preventing the row pipe body 1 from being displaced during use. Next, the multiple row pipe bodies 1 need to be sealed by a sealing ring 3. The sealing ring 3 is an annular part made of elastic material, which can fill the tiny gaps between the row pipe bodies 1 to prevent liquid or gas from leaking from the connection. The material of the sealing ring 3 usually has good elasticity and corrosion resistance, and can maintain stable sealing performance in harsh working environments. Subsequently, the plug 17 on one row pipe body 1 needs to be inserted into the connecting seat 15 on the other row pipe body 1. The key to this step is to ensure the accurate alignment of the plug 17 and the connecting seat 15 so that the subsequent locking operation can proceed smoothly. The design of the plug 17 and the connecting seat 15 often takes into account the ease of operation and structural strength, so that they can be easily connected and withstand large external forces. When the plug block 17 is inserted into the connection seat 15, the block 19 in the plug block 17 will be engaged inside the connection seat 15 to lock it. The block 19 is an elastic component that can be deformed when subjected to external force, thereby achieving a close fit with the connection seat 15. During the locking process, the block 19 is limited in the plug block 17 by the limit plate 18 to prevent it from excessive movement or falling off. At the same time, the tension support of the third spring 21 also plays a key role. It can provide a stable supporting force for the block 19 so that it can extend out of the plug block 17 and engage with the connection seat 15. When the drainage pipe body 1 needs to be disassembled for replacement or maintenance, it is only necessary to press the top column 23 on both sides of the connection seat 15. By pressing the top column 23, the top block 24 can be pushed to push the block 19 into the plug block 17. When the block 19 is completely pushed into the plug block 17, its engagement with the connection seat 15 is released, thereby achieving easy disassembly of the drainage pipe body 1.

[0033] Working principle: When using the cable prefabricated unit pipe arrangement, first of all, when it is necessary to combine multiple pipe arrangement bodies 1, it is only necessary to embed the protrusion 4 on one side of the pipe arrangement body 1 into the socket 2 of another pipe arrangement body 1. The multiple pipe arrangement bodies 1 are sealed by the sealing ring 3, and then the plug block 17 on one pipe arrangement body 1 is inserted into the connecting seat 15 on the other pipe arrangement body 1, so that the card block 19 in the plug block 17 is embedded in the connecting seat 15 for locking, and the card block 19 is limited in the plug block 17 by the limiting plate 18, and supported by the tension of the third spring 21, so that the card block 19 can extend out of the plug block 17. When the pipe arrangement body 1 needs to be disassembled and replaced, it is only necessary to press the top columns 23 on both sides of the connecting seat 15 so that the top columns 23 push the card block 19 into the plug block 17 through the top block 24, so that the card block 19 is separated from the connecting seat 15, and the pipe arrangement body 1 can be disassembled, and then the cable is installed, and the cable passes through the sleeve 7.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
