Technical Field
[0001] The utility model belongs to the technical field of construction engineering, and specifically relates to a compensation type broken line pipeline radiation protection structure. Background Art
[0002] Modern large-scale hospital buildings are often equipped with special departments such as imaging centers, nuclear medicine departments, and radiotherapy centers, which use nuclear science and technology or ionizing radiation technology to diagnose, treat, and study various diseases. To eliminate or reduce the impact of high radiation on patients, doctors, and the surrounding environment, these special functional rooms must meet the requirements of relevant radiation protection during the design and construction process. In particular, considering indoor ventilation, water, electricity, and gas supply, pipeline layout often encounters the situation of passing through the protective wall. At this time, in order to prevent the gas or fluid containing radioactive medium from diffusing through the pipeline and causing radiation leakage, reasonable structural design must be carried out for the pipeline inlet and outlet to ensure the radiation shielding effect of the wall. Content of the Utility Model
[0003] The purpose of the utility model is to provide a compensation type broken line pipeline radiation protection structure that can ensure the radiation shielding effect.
[0004] To achieve the above purpose, the compensation type broken line pipeline radiation protection structure of the utility model includes a protective wall, a protective floor slab, an internal broken line pipeline, and a first compensation protection reinforcement block. The protective floor slab is connected to the top of the protective wall. The internal broken line pipeline passes from the inside of the protective wall to the outside of the protective wall and has an indoor port that passes out from the inside of the protective wall and an outdoor port that passes out from the outside of the protective wall. The first compensation protection reinforcement block is connected between the inside of the protective wall, the internal broken line pipeline, and the protective floor slab, and the indoor port passes out from the first compensation protection reinforcement block.
[0005] In an embodiment of the above compensation type broken line pipeline radiation protection structure, it further includes a second compensation protection reinforcement block, which is connected to the outside of the protective floor slab and is located above the outdoor port.
[0006] In an embodiment of the above compensation type broken line pipeline radiation protection structure, the first compensation protection reinforcement block, the second compensation protection reinforcement block, the protective wall, the protective floor slab, and the internal broken line pipeline are integrally cast and fixed.

[0008] In an embodiment of the above-mentioned compensating fold-line pipeline radiation protection structure, the lower surface of the second compensating protection strengthening block is flush with the lower surface of the protection floor slab.
[0009] In an embodiment of the above-mentioned compensating fold-line pipeline radiation protection structure, the built-in fold-line pipeline includes an indoor connection section, an inclined section, and an outdoor connection section that are connected in sequence. The indoor connection section is parallel to the outdoor connection section, and there are bending angles between the indoor connection section and the inclined section, and between the outdoor connection section and the inclined section respectively. The bending angle is between 120° and 150°.
[0010] In an embodiment of the above-mentioned compensating fold-line pipeline radiation protection structure, the thickness of the first compensating protection strengthening block is the same as the thickness of the protection wall, and the middle of the inclined section is located at the connection between the first compensating protection strengthening block and the protection wall.
[0011] In an embodiment of the above-mentioned compensating fold-line pipeline radiation protection structure, the thickness of the protection wall and the thickness of the protection floor slab are both not less than 300 mm.

Therefore, it should not be construed as a limitation to the present utility model.
[0037] As Figure 1 and Figure 2 shown, the radiation-proof structure of the compensating folded pipeline of the present utility model includes a protective wall 100, a protective floor slab 200, an internal folded pipeline 300, and a first compensating protective strengthening block 400. The protective floor slab 200 is connected to the top of the protective wall 100. The internal folded pipeline 300 passes from the inner side of the protective wall 100 to the outer side of the protective wall 100, and has an indoor port passing out from the inner side of the protective wall 100 and an outdoor port passing out from the outer side of the protective wall 100. The first compensating protective strengthening block 400 is connected between the inner side of the protective wall 100, the indoor port of the internal folded pipeline 300, and the protective floor slab 200. Among them, the indoor port of the internal folded pipeline 300 passes out from the first compensating protective strengthening block 400, that is, the internal folded pipeline 300 penetrates through the first compensating protective strengthening block 400 and the protective wall 100 along the direction perpendicular to the thickness of the protective wall 100.
[0038] By providing the first compensating protective strengthening block 400, the present utility model can strengthen the protective wall 100 weakened by the internal folded pipeline 300 and block the direct penetration of radiation through the protective wall 100. The first compensating protective strengthening block 400 can also play a role in fixing and supporting the internal folded pipeline 300 and making its bending angle not limited by the wall thickness, which is convenient for manufacturing and use and can meet the radiation protection requirements.
[0039] The radiation-proof structure of the compensating folded pipeline of the present utility model further includes a second compensating protective strengthening block 500. The second compensating protective strengthening block 500 is connected to the outer side of the protective floor slab 200 and is located above the outdoor port of the internal folded pipeline 300. By providing the second compensating protective strengthening block 500, the present utility model compensates for the possible protective loss caused by the thinning of the protective floor slab 200 outside the protective room. Its function is to block the radiation that may remain in the internal folded pipeline 300 and propagate along the inclined section, and enhance the radiation protection effect.
[0040] The radiation protection structure of the compensated folded pipeline of the present utility model further includes a protective bottom plate 600, a protective door opening 700, an indoor pipeline 800, and an outdoor pipeline 900. Among them, the protective bottom plate 600 is connected to the bottom of the protective wall 100. The protective door opening 700 is located in the protective wall 100. The indoor pipeline 800 is hermetically connected to the indoor port of the built-in folded pipeline 300 through a connecting flange. The outdoor pipeline 900 is hermetically connected to the outdoor port of the built-in folded pipeline 300 through a connecting flange.
[0041] In the present utility model, the protective wall 100, the protective floor slab 200, the first compensation and protection strengthening block 400, the second compensation and protection strengthening block 500, and the top floor slab are cast simultaneously and integrally formed with the built-in folded pipeline. That is to say, the built-in folded pipeline 300 is integrally provided with the protective wall 100, the first compensation and protection strengthening block 400, and the second protection strengthening block 500. During the steel bar binding process, the pipeline is pre-buried and installed, avoiding the problems of using multiple materials stacked together, insecure connection, and large radiation hazards. The present utility model is integrally formed, eliminating the technological process of pasting or applying protective materials, ensuring the integrity of radiation protection, and at the same time making the construction more convenient.
[0042] The first compensation and protection strengthening block 400 is closely attached to the inner side wall of the protective wall 100 and is fixedly connected to the protective floor slab 200 and the protective wall 100 through the compensation and protection strengthening block connecting steel bars 1000. The second compensation and protection strengthening block 500 is closely attached to the outer side wall of the protective floor slab 200 and is fixedly connected to the top floor slab 200 and the protective floor slab through the compensation and protection strengthening block connecting steel bars 1000. The length of the compensation and protection strengthening block connecting steel bars 1000 extending into the top floor slab or the protective floor slab 200 should meet the anchorage requirements. The present utility model can avoid the problems of the radiation protection structure not being integrally formed at one time, having many construction steps, and large radiation hazards, and has a reasonable structural design, cost savings, better integrity and durability.
[0043] In some embodiments of the radiation protection structure of the compensated folded pipeline of the present utility model, the lower surface of the second compensation and protection strengthening block 500 is flush with the lower surface of the protective floor slab 200, and its thickness is determined by radiation protection calculation.
[0044] In some embodiments of the compensating folded pipeline radiation protection structure of the present utility model, the built-in folded pipeline 300 includes an indoor connection section 310, an inclined section 320, and an outdoor connection section 330 that are connected in sequence. The indoor connection section 310 is parallel to the outdoor connection section 330, and there are bending angles between the indoor connection section 310 and the inclined section 320, and between the outdoor connection section 330 and the inclined section 320 respectively. Preferably, the bending angle is between 120° and 150°. If the bending angle is set less than 120°, it is not conducive to the wire threading work at the later bending part. If the bending angle is set greater than 150°, the straighter the pipeline, the worse the radiation protection ability. Among them, the indoor port is the port facing the indoor of the indoor connection section 310, and the outdoor port is the port facing the outdoor of the outdoor connection section 330.
[0045] In some embodiments of the compensating folded pipeline radiation protection structure of the present utility model, the thickness of the first compensating protection strengthening block 400 is the same as the thickness of the protection wall 100. The central part of the built-in folded pipeline 300, that is, the middle part of the inclined section 320, is located at the connection between the first compensating protection strengthening block 400 and the protection wall 100, and the radiation protection effect is better.
[0046] In some embodiments of the compensating folded pipeline radiation protection structure of the present utility model, the thickness of the protection wall 100 and the thickness of the protection floor slab 200 are both not less than 300 mm. The built-in folded pipeline 300 is a galvanized steel plate pipeline, and the wall thickness is, for example, 8 - 10 mm.
[0047] In some embodiments of the compensating folded pipeline radiation protection structure of the present utility model, the first compensating protection strengthening block 400 hangs down to a position not less than 100 mm below the bottom of the built-in folded pipeline 300, that is, the first compensating protection strengthening block 400 is at least 100 mm lower than the bottom surface of the indoor connection section 310 of the built-in folded pipeline 300, to ensure the radiation protection reinforcement effect.
[0048] Preferably, the extension length of the built-in folded pipeline 300 in the horizontal direction is not less than 100 mm beyond the protection strengthening block, for the convenience of the later splicing and installation of the pipeline. That is, the indoor port of the indoor connection section 310 of the built-in folded pipeline 300 extends at least 100 mm beyond the surface of the first compensating protection strengthening block 400 in the horizontal direction, and the indoor port of the outdoor connection section 330 of the built-in folded pipeline 300 extends at least 100 mm beyond the surface of the second compensating protection strengthening block 500 in the horizontal direction, which is convenient for the connection and installation with the indoor pipeline 800 or the outdoor pipeline 900.
[0049] The compensating folded pipeline radiation protection structure of the utility model solves the problem of how to effectively protect against radiation at the position of the pipeline passing through the wall. The structure is reasonably constructed, fully integrating the principles of "blocking" and "mismatching" in radiation protection. The weakened wall at the position of the pipeline passing through the wall is "compensated" by hanging down the compensating protection strengthening block, effectively blocking the leakage of radiation and ensuring the expected radiation-proof airtight effect. In addition, the protection structure can be integrally cast, eliminating the technological process of pasting or smearing protection materials, with simple construction, reduced project costs, and better integrity and durability.
[0050] Of course, the utility model can also have many other embodiments. Without departing from the spirit and essence of the utility model, those skilled in the art can make various corresponding changes and deformations according to the utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the utility model.
