[0048] The traditional stainless steel cladding of the reactor pool of a nuclear power plant usually adopts a post-pasting construction scheme of wall surface plastering, that is, the stainless steel cladding panel is installed on the wall surface after the construction of the pool peripheral reinforced concrete wall. The traditional construction procedure is: concrete formwork construction, positioning and installation of first pre-buried components, steel bar binding, concrete pouring, scaffold and formwork removal, concrete surface finishing, support frame erection, cladding panel positioning and line laying, support angle steel installation, wall secondary plastering and groove opening, cladding panel assembly, spot welding, cladding panel welding and non-destructive testing, overall size inspection, finished product protection, and scaffold removal. The traditional pool concrete wall and pool surface stainless steel cladding are serial construction procedures, and the pool wall and pool bottom steel cladding can be constructed only after the peripheral concrete wall construction is completed, so the construction period is relatively long.

[0049] To this end, the application provides a modular steel covering installation structure and an installation method. The modular steel covering installation method is used to install the modular steel covering installation structure to shorten the construction period. The modular steel covering installation structure and the installation method will be described below, but this will not limit the technical scope of the application. It should be understood that in other embodiments, the modular steel covering installation method is not limited to installing the modular steel covering installation structure, but can also be used to install other steel covering installation structures, which are not limited herein. In addition, the installation structure and the installation method of the modular steel covering are not limited to the reactor pool, but can be installed in all pools, which are not limited herein.

[0050] Referring to Figure 1 and Figure 2 , Figure 1 and Figure 2 shows a schematic diagram of the modular steel covering installation structure in an embodiment of the application. The modular steel covering installation structure provided by the embodiment of the application comprises a first covering 1, a covering pre-embedded plate 2 and a post-supplement covering 3, a support assembly 4 and a pre-embedded assembly 5. The support assembly 4 is fixedly connected with the first covering 1, and the covering pre-embedded plate 2 is fixedly connected with the pre-embedded assembly 5. First, the support assembly 4 is pre-embedded in the pool wall, and the first covering 1 is fixed. Then, the pre-embedded assembly 5 is pre-embedded in the pool wall, and the covering pre-embedded plate 2 is fixed. There is a gap between the covering pre-embedded plate 2 and the pool wall, and the gap is used to fill the connecting agent 20, which can be mortar or lime. The post-supplement covering 3 is provided with a gap slot 30 adapted to the covering pre-embedded plate 2, and the post-supplement covering 3 is installed between the covering pre-embedded plate 2 and the first covering 1 and is fixed by the connecting agent 20. The post-supplement covering 3 is welded with the covering pre-embedded plate 2, and the post-supplement covering 3 is welded with the first covering 1. The weld between the post-supplement covering 3 and the covering pre-embedded plate 2 is set as the first weld 6, and the weld between the post-supplement covering 3 and the first covering 1 is set as the second weld 7.

[0051] Referring to Figure 3 and Figure 4 , the support assembly 4 is pre-embedded in the pool wall, and the first covering 1 is fixed on the side of the support assembly 4 away from the pool wall. In combination with Figure 1 , the support assembly 4 comprises a horizontally fixed rod 40 and a vertically fixed rod 41 fixedly connected, and a plurality of horizontally fixed rods 40 and vertically fixed rods 41 are arranged in a staggered manner to form a frame structure. In this embodiment, the horizontally fixed rod 40 and the vertically fixed rod 41 are specifically angle steels. On the side of the horizontally fixed rod 40 and the vertically fixed rod 41 facing the pool wall, an anchor 42 is fixedly connected, which is specifically an angle steel in this embodiment, and can also be an anchor bolt in other embodiments. The cross sections of the horizontally fixed rod 40, the vertically fixed rod 41 and the anchor 42 are all set as L-shaped, so as to increase the connection effect between the first covering 1 and the pool wall, and avoid the first covering 1 from falling off.

[0052] Referring to Figure 2The pre-embedded assembly 5 comprises a first pre-embedded plate 50 pre-embedded in the pool wall body, a mounting ring 51 fixed to the side of the first pre-embedded plate 50 away from the pool wall body, a mounting block 52 fixed to the side of the covering pre-embedded plate 2 facing the mounting ring 51, and a mounting groove 53 for inserting a bolt formed in the mounting block 52. The first pre-embedded plate 50 is first embedded in the pool wall body, and then the mounting block 52 is inserted into the mounting ring 51, and the covering pre-embedded plate 2 is positioned by the bolt, so as to realize the installation of the covering pre-embedded plate 2. The installation precision is improved, and the connection error between the covering pre-embedded plate and the post-covering is reduced, so that the installed modular steel covering meets the processing requirements.

[0053] By the modular construction mode of installing the first covering 1 first, then installing the covering pre-embedded plate 2, and finally installing the post-covering 3, the existing serial construction process can be adjusted to parallel construction, so that the on-site construction period of the pool steel covering is greatly shortened. In addition, the welding, non-destructive testing and other work between the first covering 1, the covering pre-embedded plate 2 and the post-covering 3 are no longer restricted by the on-site construction space, and can use machine tools, automatic welding machines, RT testing equipment and other equipment, so that the welding and non-destructive testing difficulty is reduced, and the construction quality and efficiency are improved. After the steel covering adopts the modular structure, the on-site construction requirement of the module is only the butt welding of the modules, and the on-site labor demand is greatly reduced, thereby reducing the on-site construction risk. In addition, the original secondary plastering layer thickness in the wall body is cancelled, and the thickness of the wall body is reduced.

[0054] During the operation of the nuclear power plant, once the steel covering leaks, the safety risk caused by the radioactive substances in the pool is huge. Therefore, the leakage collection assembly 8 is arranged on the side of the first covering 1 and the post-covering 3 facing the pool wall body and the side of the covering pre-embedded plate 2 and the post-covering 2 facing the pool wall body, for collecting the leakage liquid. The leakage collection assembly 8 is communicated with a groove (not shown in the figure), and the groove is communicated with a waste pool pit (not shown in the figure), so as to introduce the leakage liquid into the waste pool pit through the groove, and realize the accurate control and positioning of the leakage liquid and the leakage point.

[0055] Referring to Figure 5 and Figure 6For example, the leakage collection assembly 8 between the first coating 1 and the after coating 3 includes a support plate 85, a first collection plate 86 and a second collection plate 87. The support plate 85 is fixed between the first coating 1 and the after coating 3, and is used to support the second weld 7 and provide a support backing for welding, but does not bear. The first collection plate 86 is welded with the support plate 85, and the first collection plate 86 is welded with the first coating 1, and a first leakage groove 88 is formed between the first collection plate 86 and the first coating 1. The cross section of the first collection plate 86 is V-shaped in this embodiment, and can also be U-shaped, L-shaped or C-shaped in other embodiments. The second collection plate 87 is welded with the support plate 85, and the second collection plate 87 is welded with the after coating 3, and a second leakage groove 89 is formed between the second collection plate 87 and the after coating 3. The cross section of the second collection plate 87 is L-shaped in this embodiment, and can also be U-shaped, V-shaped or C-shaped in other embodiments. The first leakage groove 88 and the second leakage groove 89 are used to collect the leakage liquid on both sides of the second weld 7, and to avoid the safety risk caused by radioactive substances as much as possible.

[0056] An embodiment of the present application also provides a modular steel coating installation method, including the following steps:

[0057] The first coating 1 is embedded, the anchor 42 and the support assembly 4 are fixedly installed on one side of the first coating 1 facing the pool wall, and the leakage collection assembly 8 is fixedly installed on one side of the first coating 1 facing the pool wall. The leakage collection assembly 8 is installed along the edge of the first coating 1, the anchor 42 and the support assembly 4 are embedded in the pool wall, and the concrete is poured to fix the first coating 1;

[0058] The coating embedded plate 2 is embedded, the embedded assembly 5 is fixedly installed on one side of the coating embedded plate 2 facing the pool wall, and the leakage collection assembly 8 is fixedly installed on one side of the coating embedded plate 2 facing the pool wall. The leakage collection assembly 8 is installed along the edge of the coating embedded plate 2, and then the embedded assembly 5 is embedded in the pool wall, and the concrete is poured to fix the coating embedded plate 2;

[0059] A gap is reserved between the coating embedded plate 2 and the first coating 1, and the gap is filled with mortar or lime for installation and positioning of the after coating 3,

[0060] The after coating 3 is installed, the after coating 3 is installed in the gap, and the after coating is fixed by the mortar or lime; then the first weld 6 between the after coating 3 and the coating embedded plate 2 is welded, and the second weld 7 between the after coating 3 and the first coating 1 is welded;

[0061] When the first weld 6 and the second weld 7 leak, the leakage liquid flows into the first leakage groove 88 and the second leakage groove 89, and finally flows into the groove together, and is drained to the specified waste pit through the groove.

[0062] By adopting the above installation method, the steel facing is divided into a plurality of different sub-modules of a first attached facing, a facing pre-embedded plate and a post-supplemented facing, which are prefabricated in the factory. At the construction site, only the butt joint and welding between the modules are needed, and then the whole is hoisted and poured and formed together with the pool wall, so that the modular steel facing and the pool wall construction process can be parallel, the on-site construction period of the steel facing is greatly shortened, thereby shortening the construction period of the key path of the safety plant civil construction occupying the safety plant, and obviously contributing to reducing the construction period of the safety plant. Further, the welding, non-destructive testing and other work are no longer restricted by the on-site construction space, and can use machine tools, automatic welding machines, RT testing equipment and other equipment, the welding and non-destructive testing difficulty is reduced, the construction quality is improved, and the construction efficiency is improved. In addition, the first attached facing and the post-supplemented facing installed by the above installation method are provided with a leakage collection assembly, which is helpful for accurately positioning the leakage point in the pool and accurately controlling the leakage liquid.

[0063] In addition, referring to Figure 7 , Figure 7 The structure of the leakage collection assembly in another embodiment of the present application is shown, which is different from the previous embodiment in that the leakage collection assembly 8 is specifically a U-shaped plate or a W-shaped plate. Taking the W-shaped plate as an example, the W-shaped plate includes a first collection part 80, a second collection part 81 and a support part 82 which are integrally formed. The support part 82 is arranged between the first collection part 80 and the second collection part 81. The first collection part 80 is welded to the side of the first attached facing 1 facing the pool wall, and there is a first collection groove 83 between the first collection part 80 and the first attached facing 1. The second collection part 81 is welded to the side of the post-supplemented facing 3 facing the pool wall, and there is a second collection groove 84 between the second collection part 81 and the post-supplemented facing 3. The support part 82 is in contact with the second weld 7 between the first attached facing 1 and the post-supplemented facing 3, which provides a support backing plate for welding but does not bear. On the one hand, when leakage occurs at the second weld 7, the leakage liquid can enter the first collection groove 83 and the second collection groove 84, realizing the collection of the leakage liquid. On the other hand, the support part 82 can provide support for the welding position, facilitating the welding operation.

[0064] Referring to Figure 8 , Figure 8A structural schematic diagram of the pre-embedded component 5 in another embodiment of the application is shown, which is different from the above-mentioned embodiment in that the pre-embedded component 5 comprises a third pre-embedded plate 54, which is pre-embedded in the pool wall body, and the covering pre-embedded plate 2 is welded on the side of the third pre-embedded plate 54 away from the pool wall body. The side of the covering pre-embedded plate 2 away from the pool wall body is provided with a groove 56 for connecting the post-covering 3. The first pasting covering 1 is pre-embedded in the pool wall body through the support assembly 4, and then the third pre-embedded plate 54 is pre-embedded in the pool wall body to fix the covering pre-embedded plate 2. Finally, the post-covering 3 is installed between the first pasting covering 1 and the covering pre-embedded plate 2, and a plastering area 57 is formed between the post-covering 3 and the pool wall body. The plastering area 57 is plastered first, and then the post-covering 3 is fixed in the plastering area 57 between the first pasting covering 1 and the covering pre-embedded plate 2. At this time, the end of the post-covering 3 close to the covering pre-embedded plate 2 is arranged in the groove 56. Finally, the gap between the post-covering 3 and the first pasting covering 1 is welded, and the gap between the post-covering 3 and the covering pre-embedded plate 2 is welded. Through the above installation method, the installation is convenient, which helps to improve the installation efficiency.

[0069] The post-covering 3 is installed, the post-covering 3 is installed in the plastering area 57, and the post-covering 3 is fixed by plastering. The first weld 6 between the post-covering 3 and the covering pre-embedded plate 2 is welded, and the second weld 7 between the post-covering 3 and the first pasting covering 1 is welded;

[0070] When the first weld 6 and the second weld 7 leak, the leakage flows into the first leakage groove 88 and the second leakage groove 89, and then flows into the groove together, and is guided to the designated waste pit through the groove.
