[0044] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0047] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0048] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] Please refer to Figures 1 to 4 As shown, this utility model proposes a pipe gallery system, which includes a pipe gallery structure 100, a conveying pipeline 200, a recycling device 300, and a first pumping device 400.

[0050] The utility model's pipe gallery system has a pipe gallery channel 110, and the pipe gallery structure 100 can protect the structure housed in the pipe gallery channel 110, thereby reducing the contact between the structure housed in the pipe gallery channel 110 and the structure outside the pipe gallery structure 100.

[0051] The conveying pipe 200 of this invention is disposed inside the pipe gallery channel 110 and has a conveying channel 210 for conveying liquid effluent. Liquid effluent discharged from the nuclear power plant can be conveyed through the conveying pipe 200 of this invention into the receiving water body in the sea, thereby realizing the long-distance liquid effluent discharge from the nuclear power plant. Since the conveying pipe 200 is disposed inside the pipe gallery channel 110, the pipe gallery structure 100 can protect the conveying pipe 200, and when liquid effluent accidentally flows out of the conveying channel 210, the pipe gallery channel 110 can also temporarily store the liquid effluent, reducing leakage of liquid effluent to the external environment.

[0052] Without departing from the inventive concept of this utility model, those skilled in the art can choose the material for the pipe gallery structure 100. In some embodiments, the pipe gallery structure 100 is made of one or more of steel, soil, and stone materials. As a preferred embodiment, the pipe gallery structure 100 is made of reinforced concrete.

[0053] The recovery device 300 of this invention is used to recover liquids. It should be noted that the liquid effluent referred to in this invention refers to radioactive materials that are released into the environment in liquid form during the normal operation of a nuclear power plant and subsequently diluted and dispersed. The term "liquid" in this invention is not limited to the liquid effluents defined herein, but also includes environmental water that may leak from the outside of the pipe rack structure 100 into the pipe rack channel 110, etc. Therefore, those skilled in the art should understand that the recovery device 300 can also recover and process liquid effluents that enter the recovery device 300.

[0054] The first pumping device 400 of this invention is installed in the pipe gallery channel 110 and configured to pump the liquid in the pipe gallery channel 110 into the recovery device 300. Through this scheme, the first pumping device 400 can pump the liquid effluent from the pipe gallery channel 110 into the recovery device 300 for recovery, thereby reducing the retention of liquid effluent in the pipe gallery channel 110 and reducing the possibility of liquid effluent leaking into the external environment through the pipe gallery structure 100. On the other hand, recovering the liquid effluent into the recovery device 300 facilitates subsequent processing of the liquid effluent flowing from the conveying channel 210 by workers, reducing the leakage of liquid effluent into the external environment.

[0055] Without departing from the inventive concept of this utility model, those skilled in the art can design the structure of the recycling device 300 themselves. In some embodiments, the recycling device 300 includes a liquid storage tank made of radiation-proof material, disposed outside the pipe gallery structure 100, and a first pumping device 400 capable of pumping liquid in the pipe gallery channel 110 into the liquid storage tank. Through the above scheme, the liquid effluent flowing into the pipe gallery channel 110 can be specially stored in the liquid storage tank, facilitating centralized processing by subsequent personnel.

[0056] As a preferred option, please refer to Figures 1 to 4 As shown, in some embodiments, the recovery device 300 includes a maintenance drainage pipe 310, which is housed within the pipe gallery channel 110 and used to transport liquid along the extension direction of the conveying pipeline 200. Through this scheme, the liquid effluent from the pipe gallery channel 110 can be directly drawn into the maintenance drainage pipe 310 by the action of the first pumping device 400, and continue to be transported along the extension direction of the conveying pipeline 200, thereby quickly delivering the liquid effluent flowing into the pipe gallery channel 110 into the receiving water body of the sea. On the other hand, since the maintenance drainage pipe 310 is housed within the pipe gallery channel 110, the pipe gallery structure 100 can further protect the maintenance drainage pipe 310, eliminating the risk of the liquid effluent within the maintenance drainage pipe 310 directly leaking to the outside.

[0057] Furthermore, in some embodiments, the utility tunnel system also includes a radioactivity monitoring sensor 500 and an alarm device (not shown). The radioactivity monitoring sensor 500 is located in the utility tunnel passage 110 and is used to monitor the radioactivity of the liquid within the passage 110. The alarm device is configured to sound an alarm when the radioactivity monitoring sensor 500 detects radioactivity within the passage 110. Since the liquid effluent contains a small amount of radioactivity, the radioactivity monitoring sensor 500 can detect the radioactivity in the temporarily stored liquid effluent, and the alarm device will also sound an alarm when the radioactivity monitoring sensor 500 detects radioactivity within the passage 110, thereby alerting staff to the abnormal outflow of liquid effluent and facilitating subsequent handling by staff.

[0058] It should be noted that ambient water outside the utility tunnel structure 100 may enter the utility tunnel passage 110 through natural seepage. The alarm device will only alert staff when the radioactivity monitoring sensor 500 detects radioactive substances in the liquid inside the utility tunnel passage 110, which helps staff to accurately determine whether a leak has occurred inside the utility tunnel passage 110.

[0059] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the position of the radioactivity monitoring sensor 500. In some embodiments, the radioactivity monitoring sensor 500 is disposed at the inlet of the first pumping device 400. In some embodiments, the radioactivity monitoring sensor 500 is disposed in the recovery device 300.

[0060] Please refer to Figures 1 to 4 As shown, in some embodiments, the pipe gallery channel 110 has a first sump 120, which is located at the bottom of the pipe gallery structure 100. Through this design, the liquid within the pipe gallery channel 110 is collected by the first sump 120 due to gravity, which facilitates liquid processing by the device.

[0061] Specifically, as previously described, the scheme of installing a radioactive monitoring sensor 500 and an alarm device in the utility tunnel system, combined with the above scheme, in some embodiments, the radioactive monitoring sensor 500 is installed in the first sump 120 and used to monitor the radioactive substances in the liquid within the first sump 120. The radioactive monitoring sensor 500 installed in the first sump 120 can monitor the liquid within the utility tunnel 110 more quickly, thereby enabling the alarm device to promptly alert personnel when the radioactive monitoring sensor 500 detects radioactive substances, further reducing the risk of liquid leakage.

[0062] Furthermore, in some embodiments, the first pumping device 400 is configured to pump the liquid in the first sump 120 into the recovery device 300 when the liquid level in the first sump 120 reaches a preset value. Through this scheme, the first pumping device 400 can pump out the liquid in the pipe gallery channel 110 more quickly, which helps to reduce the residence time of the liquid in the pipe gallery channel 110. When liquid effluent flows into the pipe gallery channel 110 from the conveying channel 210, the first pumping device 400 can also reduce the residence time of the liquid effluent in the pipe gallery channel 110, further reducing the risk of liquid effluent leakage.

[0063] It should be noted that those skilled in the art can adjust the preset value themselves and can also choose the method of adjusting the preset value. For example, in some embodiments, the pipe gallery system also includes a liquid level sensor, which is disposed within the first sump 120 and has a preset distance from the bottom of the first sump 120. This preset distance is the preset value. When the liquid in the first sump 120 exceeds the liquid level sensor, the first pumping device 400 pumps the liquid in the first sump 120 into the recovery device 300. Through the above scheme, those skilled in the art can adjust the preset value by adjusting the distance between the liquid level sensor and the bottom of the first sump 120.

[0064] Without departing from the inventive concept of this utility model, those skilled in the art can further adjust the pipe gallery structure 100.

[0065] Furthermore, in some embodiments, the pipe gallery channel 110 has a second sump 130, which is located at the bottom of the pipe gallery structure 100. The first sump 120 and the second sump 130 are located on different sides of the conveying channel 210 in a first direction, which is perpendicular to the extension direction of the conveying channel 210 and parallel to the horizontal plane. The pipe gallery system also includes a second pumping device (not shown in the figure), which is configured to pump the liquid in the second sump 130 into the recovery device 300 when the liquid level in the second sump 130 reaches a preset value. With the above solution, since the first sump 120 and the second sump 130 are located on different sides of the conveying channel 210 in the first direction, liquid effluent from the conveying channel 210 that accidentally flows into the pipe gallery channel 110 from the conveying channel 210 will quickly enter the sump due to its own gravity. The first pumping device 400 and the second pumping device can collect the liquid in the first collection pit 120 and the second collection pit 130 respectively, which helps to further reduce the residence time of the liquid in the pipe gallery channel 110. When the liquid effluent flows into the pipe gallery channel 110 from the conveying channel 210, the first pumping device 400 and the second pumping device can also further reduce the residence time of the liquid effluent in the pipe gallery channel 110, and further reduce the risk of liquid effluent leakage.

[0066] Further, please refer to Figures 1 to 4 As shown, in some embodiments, the pipe gallery system further includes a second sump 130, which is located at the bottom of the pipe gallery structure 100, and the bottom of the second sump 130 is higher than the first sump 120. The first sump 120 and the second sump 130 are located on different sides of the conveying channel 210 in a first direction, which is perpendicular to the extension direction of the conveying channel 210 and parallel to the horizontal plane. The pipe gallery channel 110 also includes a connecting channel 140, one end of which is connected to the first sump 120 and the other end of which is connected to the second sump 130, so that the liquid in the second sump 130 can flow into the first sump 120 through the connecting channel 140.

[0067] Through the above scheme, since the first collection pit 120 and the second collection pit 130 are located on different sides of the conveying channel 210 in the first direction, the liquid effluent in the conveying channel 210, after accidentally flowing into the pipe gallery channel 110 from the conveying channel 210, quickly enters the collection pit due to its own gravity. Furthermore, since the bottom of the second collection pit 130 is higher than the first collection pit 120, and the two ends of the connecting channel 140 are connected to the first collection pit 120 and the second collection pit 130 respectively, the liquid in the second collection pit 130 can flow into the first collection pit 120. Therefore, liquid effluent leaking into the conveying channel 210 along different sides in the first direction can be collected in the first collection pit 120 and then pumped into the recovery device 300 by the first pumping device 400, shortening the residence time of the liquid effluent and reducing the risk of leakage.

[0068] It should be noted that this utility model does not limit the form of the first water collection pit 120 and the second water collection pit 130. Please refer to... Figure 1 , Figure 4 As shown, in some embodiments, the bottom wall of the pipe gallery channel 110 has a mounting surface 160, and the first water collection pit 120 and the second water collection pit 130 are recessed relative to the mounting surface 160 to increase the water collection capacity of the first water collection pit 120 and the second water collection pit 130, and to facilitate the first pumping device 400 and the second pumping device to remove the liquid in the water collection pit. Please refer to... Figure 2 , Figure 3 As shown, in some other embodiments, the first sump 120 is defined by the right side of the pipe wall of the conveying pipe 200 and the right side of the pipe gallery structure 100, and the second sump 130 is defined by the left side of the pipe wall of the conveying pipe 200 and the left side of the pipe gallery structure 100. That is, the first sump 120 and the second sump 130 can be configured with the mounting surface 160 as the bottom surface and disposed on the mounting surface 160.

[0069] Furthermore, without departing from the inventive concept of this utility model, those skilled in the art can also adjust the structure of the pipe gallery system, thereby adjusting the form of the connecting channel 140 so that the liquid in the second sump 130 can flow into the first sump 120 through the connecting channel 140.

[0070] Please refer to Figure 1As shown, in some embodiments, the pipe gallery structure 100 defines a connecting channel 140 located below the mounting surface 160. Understandably, in the case where the conveying pipe 200 is placed directly on the mounting surface 160, the first sump 120 and the second sump 130 located on either side of the conveying pipe 200 in the first direction are isolated by the conveying pipe 200. By connecting the first sump 120 and the second sump 130 through the connecting channel 140 located below the mounting surface 160, the conveying pipe 200 can be avoided, and liquid effluent from the second sump 130 can enter the first sump 120 through the connecting channel 140, thereby collecting all liquid effluent leaking to either side of the conveying pipe 200 in the first sump 120.

[0071] Please refer to Figure 2 As shown, in some embodiments, the bottom wall of the pipe gallery channel 110 has an mounting surface 160. The pipe gallery system includes multiple supports 600, which are spaced apart along the extension direction of the pipe gallery channel 110. The conveying pipe 200 is fixed to the mounting surface 160 by the multiple supports 600. The mounting surface 160, the conveying pipe 200, and two adjacent supports 600 together define a connecting channel 140. In this case, since the conveying pipe 200 is supported by the supports 600 and is located above the mounting surface 160, the space below the conveying pipe 200 and between adjacent supports 200 can connect the first sump 120 and the second sump 130 located on both sides of the conveying pipe 200 along the first direction. In this way, the space above the mounting surface 160 can be directly used to form the connecting channel 140, which simplifies the construction of the connecting channel 140 and collects the liquid effluent leaked to both sides of the conveying pipe 200 in the first direction into the first sump 120.

[0072] Further, please refer to Figure 3 As shown, in some embodiments, the bottom wall of the connecting channel 140 also has a first inclined surface 150, the height of which gradually decreases from the second collection pit 130 to the first collection pit 120. With this design, when the liquid in the second collection pit 130 flows into the first collection pit 120 through the connecting channel 140, it is guided by the first inclined surface 150, thus accelerating its entry into the first collection pit 120 and allowing it to be pumped into the recovery device 300 more quickly by the first pumping device 400, reducing the risk of liquid leakage.

[0073] In the case of a pipe gallery system including multiple supports 600, the conveying pipe 200 is fixed to the mounting surface 160 by multiple supports 600. The multiple supports 600 can jointly support the conveying pipe 200, ensuring the stability of the conveying pipe 200. When external vibration occurs, the supports 600 can absorb some of the vibration energy, thereby reducing the vibration of the conveying pipe 200 and helping to extend the service life of the conveying pipe 200.

[0074] Furthermore, the utility tunnel system may have a first sump 120 provided only on one side of the support 600 along the first direction, the first direction being perpendicular to the extension direction of the conveying channel 210 and parallel to the horizontal plane; alternatively, a first sump 120 and a second sump 130 may be provided on opposite sides of the support 600 along the first direction. Additionally, the first sump 120 and the second sump 130 may be configured with the mounting surface 160 as their bottom surface and positioned above the mounting surface 160, or they may be recessed downwards relative to the mounting surface 160, forming a depression.

[0075] In some specific embodiments, please refer to Figure 4 As shown, the bottom wall of the second sump 130 is higher than the bottom wall of the first sump 120. The pipe gallery structure 100 also has a connecting channel 140, which is located below the support 600. One end of the connecting channel 140 is connected to the first sump 120, and the other end is connected to the second sump 130, so that the liquid in the second sump 130 can flow into the first sump 120 through the connecting channel 140. Since the bottom of the second sump 130 is higher than the first sump 120, and the two ends of the connecting channel 140 are connected to the first sump 120 and the second sump 130 respectively, the liquid in the second sump 130 can flow into the first sump 120 and be pumped into the recovery device 300 by the first pumping device 400. The above scheme can further reduce the residence time of liquid effluent on the side of the support 600 away from the first sump 120 in the pipe gallery channel 110, reducing the risk of leakage.

[0076] Further, please refer to Figure 4 As shown, in some embodiments, the pipe gallery system further includes a first ramp 700, which is accommodated in the pipe gallery channel 110 and disposed on the mounting surface 160. The support 600 is higher than the first ramp 700. In a first direction, the first ramp 700 is located between the first sump 120 and the support 600, and is connected to the side of the support 600 near the first sump 120. The height of the first ramp 700 gradually decreases along the direction near the first sump 120. Through this design, the liquid located between the first sump 120 and the support 600 will be guided by the first ramp 700 and quickly enter the first sump 120, facilitating its rapid pumping into the recovery device 300 by the first pumping device 400.

[0077] Please refer to Figure 4As shown, the utility tunnel system also includes a second ramp 800, which is housed within the utility tunnel passage 110 and positioned on the mounting surface 160. The support 600 is higher than the second ramp 800. In a first direction, the second ramp 800 is located between the support 600 and the second sump 130, connecting the support 600 to the side closer to the second sump 130, and the height of the second ramp 800 gradually decreases along the direction closer to the second sump 130. Through this design, the liquid located between the second sump 130 and the support 600 will be guided by the second ramp 800 and quickly enter the first sump 120, facilitating rapid pumping by the first pumping device 400 into the recovery device 300.

[0078] Without departing from the inventive concept of this utility model, those skilled in the art can make other improvements to the pipe gallery structure 100.

[0079] For example, please refer to Figures 1 to 4 As shown, in some embodiments, the pipe gallery structure 100 includes a channel structure 170 and a cover plate 180. The cover plate 180 is detachably connected to the top of the channel structure 170 to close the pipe gallery channel 110 or to connect the upper part of the pipe gallery channel 110 to the outside. With this solution, when workers need to inspect the conveying pipeline 200, the first pumping device 400, and the pipe gallery structure 100, they can lift the cover plate 180 and directly enter the pipe gallery channel 110 for inspection, simplifying the inspection process.

[0080] As mentioned earlier, the system of utility tunnels is equipped with radioactive monitoring sensors 500 and alarm devices. In conjunction with the above scheme, before maintenance is carried out, staff can lift the cover 180 and enter the utility tunnel passage 110 to carry out maintenance by the alarm device.

[0081] In some embodiments, the utility tunnel system further includes a plain concrete cushion layer 900, which is located outside the utility tunnel structure 100 and supports the bottom of the utility tunnel structure 100. Through this design, the plain concrete cushion layer 900 supporting the bottom of the utility tunnel structure 100 on the outside can further enhance the overall compressive strength of the utility tunnel, thereby increasing the overall strength of the utility tunnel structure 100, and thus improving the protection of the transport pipeline 200, which is beneficial to improving the stability of the transport pipeline 200 in transporting liquid effluents.

[0082] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
