Description

Technical Field

[0001] The invention relates to a pressurized building, and in particular to a module unit, an assembled sealed pressurized single-cabin cabin body and a multi-cabin cabin body. Background Art

[0002] Conventional buildings usually use simple oxygen supplementation to alleviate altitude sickness, which cannot eliminate the impact of low pressure. The common pressurized equipment on the market is expensive and has a single function, which cannot meet the needs of long-term living. Pressurized buildings can restore the main indoor environmental indicators in high-altitude areas to those in plain areas. The cost is much lower than that of pressurized equipment, and there are more functional areas to meet the needs of long-term living. Due to the airtightness requirements, pressurized buildings often use welding to manufacture single-cabin cabins. There are problems that they cannot be transported indoors after manufacturing or that indoor welding poses a fire hazard. Therefore, it is difficult to use them in indoor spaces. Moreover, during the transportation of the manufactured cabin, the size of the single-cabin cabin cannot be increased due to the limitations of the transportation vehicles, and it cannot respond to the needs of larger volumes. Therefore, when a larger pressurized building is required, multiple modular pressurized single cabins are generally assembled into a pressurized building complex.

[0003] However, the current modular pressurized single cabins have the following problems: 1) The splicing efficiency between pressurized single cabins is slow. In order to ensure the sealing effect, welding sealing is generally used at the splicing points, which further reduces the splicing efficiency; 2) The pressurized single cabins generally include pressurized single cabins as living modules, pressurized single cabins as connecting modules, pressurized single cabins as transition modules, pressurized single cabins as aisle modules, etc. Therefore, not only do it need to set up a variety of different forms of pressurized single cabins, which increases the manufacturing cost, but the connecting modules and transition modules also need to be equipped with pressure-bearing sealing walls. Therefore, the huge steel consumption caused by the extended connection and the large number of pressure-bearing sealing walls further increase the cost and affect the popularization and promotion of the product. Summary of the invention

[0004] The object of the present invention is to provide a modular unit, and an assembled sealed pressurized single-cabin hull based on the above modular unit, and an assembled sealed pressurized multi-cabin hull based on the above modular unit. The modular unit has high splicing efficiency and improves the sealing effect. According to the characteristics of the modular unit, both the single-cabin hull and the multi-cabin hull can be assembled on-site in any place, and can be spliced ​​without welding and ensure sealing after splicing, thereby meeting the requirements of large volume and random combination, reducing customization costs, requiring less steel, and lowering costs.

[0005] The technical solution adopted by the present invention is: A modular unit is used to be spliced ​​with each other to form a sealed pressurized cabin, the modular unit includes a central space formed by a pressure-bearing sealing surface and one or more connecting parts sealedly connected to adjacent modular units; continuous protrusions and continuous grooves are arranged on the connecting end surface of the connecting part, and the connecting part includes a connecting part A and a connecting part B; the protrusion of the connecting part A is on the outer side of the end surface, and the groove is on the inner side of the protrusion; the protrusion of the connecting part B is on the inner side of the end surface, and the groove is on the outer side of the end surface; a continuous sealing member is installed in the groove; adjacent modular units are connected by plugging the corresponding protrusions and grooves of the connecting parts A and B, and the protrusion squeezes the sealing member in the groove, so as to form a double-layer seal at the connecting part.

[0006] Furthermore, the sealing member has a cavity, and the size of the groove is larger than the size of the protrusion and the sealing member.

[0007] Preferably, the cross-sections of the groove, the protrusion and the seal are rectangular, there is a gap between the seal and both sides of the groove when the seal is not squeezed, and the width of the protrusion is narrower than the width of the seal.

[0008] Preferably, the bottom of the groove adopts an inwardly concave arc surface, and the bottom of the seal adopts an outwardly convex arc surface matching the arc surface of the bottom of the groove. The seal fits with both sides of the groove in an unextruded state, and an exhaust channel is provided on the outer side of the groove.

[0009] Preferably, the bottom of the groove adopts an outwardly convex arc surface, and the bottom of the seal adopts an inwardly concave arc surface matching the arc surface of the bottom of the groove. The seal fits with both sides of the groove in an unextruded state, and an exhaust channel is provided on the outer side of the groove.

[0010] Furthermore, a flange is provided on the connecting end surface of the connecting portion, and adjacent module units are butt-connected by matching the flange with the connecting piece, and through holes for matching the connecting piece are distributed along the flange.

[0011] Furthermore, one side or both sides of the top are provided with an expansion strip for cooperating with the connecting piece to realize horizontal splicing, and through holes for cooperating with the connecting piece are distributed along the expansion strip.

[0012] Preferably, the connecting piece adopts a combination of bolts and nuts, and the bolts are locked by nuts on one side after passing through the through holes on both sides; or, the connecting piece adopts a combination of studs and nuts, and the studs are locked by nuts on both sides after passing through the through holes on both sides.

[0014] A modular sealed pressurized multi-cabin cabin, wherein the cabin is formed by a plurality of module units spliced ​​together longitudinally and transversely; as for the type of module units, if transverse splicing is involved, the above-mentioned module units with extension strips are used, and if transverse splicing is not involved, any of the above-mentioned module units are used; pressure-bearing sealing surfaces are added to the ends of the cabin for closure, and pressure-bearing doors and windows are added to the pressure-bearing sealing surfaces at required positions; the longitudinal internal spaces in the same row are connected or partitioned to divide different functional areas.

[0015] The beneficial effects of the present invention are: 1. In the module unit: First, adjacent module units are plugged in through protrusions and grooves, and the plugging efficiency is high. After plugging in, the protrusion is inserted into the groove to squeeze the seal to achieve sealing. The sealing is achieved while plugging in, and the splicing efficiency is high; second, the protrusions and grooves on the connection part A and the connection part B are staggered to form a double-layer seal with two layers inside and outside; third, the protrusions and grooves on the connection part A and the connection part B are staggered, and the protrusions and grooves cannot cooperate when the docking direction is wrong, which can effectively prevent mistakes; fourth, the protrusions and grooves on the connection part A and the connection part B are staggered, and the sealing path is more complicated, which can form a labyrinth seal and have a better sealing effect; fifth, at each layer of sealing, the protrusion is inserted into the groove to squeeze the seal, and the seal forms a three-sided seal on the outside with the bottom surface and two side surfaces of the groove, and forms a three-sided seal on the inside with the bottom surface and two side surfaces of the protrusion, ensuring sufficient sealing contact surfaces and improving the sealing effect.

[0016] 2. In the single-cabin cabin and the multi-cabin cabin: the single-cabin cabin adopts a longitudinal splicing structure, whose transverse width is fixed and the longitudinal length can be set according to actual needs; the multi-cabin cabin adopts a longitudinal and transverse splicing structure, whose transverse width and longitudinal length can be set according to actual needs; both can be assembled on-site in any place. The key is - first, the two realize welding-free splicing and ensure the sealing after splicing, thus solving the problems of transportation restrictions and indoor welding, meeting the requirements of large volume and random combination, and restoring the main indoor environmental indicators in high-altitude areas to those in plain areas; second, both are spliced ​​by basic module units, reducing customization costs, canceling connection modules and transition modules, reducing the pressure-bearing sealing walls of connection modules and transition modules, requiring less steel, and lowering costs, which is conducive to product promotion.

[0017] 3. The seal has a cavity, and the size of the groove is larger than that of the protrusion and the seal: First, when the protrusion compresses the elastic seal, the cavity can provide a certain degree of deformation, and the gas inside the cavity can provide a certain degree of rebound, so that the elastic seal is closer to the inner wall of the groove and the outer surface of the protrusion, forming a surface seal, thereby ensuring the sealing effect at the joint; Second, the size of the groove is slightly larger than that of the protrusion and the elastic seal. On the one hand, the protrusion has a small-sized displacement redundancy in the groove, which makes it easier for the protrusion and the groove to dock when adjacent module units are longitudinally spliced, avoiding docking failure caused by manufacturing and installation errors. On the other hand, it provides a certain space for the deformation of the seal so that it can fit more closely. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] The features and performance of the present application are further described in detail below in conjunction with the embodiments.

[0037] Embodiment 1 This embodiment discloses a modular unit for being connected to form a sealed pressurized cabin. Figure 1 a) Figures 3 to 5As shown: the module unit includes a middle space formed by a pressure-bearing sealing surface and one or more connecting parts sealed and connected to adjacent module units; continuous protrusions 4 and continuous grooves 5 are arranged on the connecting end surface of the connecting part, and the connecting part includes a connecting part A and a connecting part B; the protrusion 4 of the connecting part A is on the outer side of the end surface, and the groove 5 is on the inner side of the protrusion 4; the protrusion 4 of the connecting part B is on the inner side of the end surface, and the groove 5 is on the outer side of the end surface; a continuous sealing member 6 is installed in the groove 5; the adjacent module units are connected by plugging the corresponding protrusions 4 and grooves 5 of the connecting parts A and B, and the protrusion 4 squeezes the sealing member 6 in the groove 5, so as to form a double-layer seal at the connecting part.

[0038] This module unit belongs to the basic model. In this module unit: first, adjacent module units are plugged in through protrusions 4 and grooves 5, and the plugging efficiency is high. After plugging in, the protrusion 4 is inserted into the groove 5 to squeeze the seal 6 to achieve sealing. The plugging is sealed at the same time, and the splicing efficiency is high; second, the protrusions 4 and grooves 5 on the connection part A and the connection part B are staggered, which can form a double-layer seal of the inner and outer layers; third, the protrusions 4 and grooves 5 on the connection part A and the connection part B are staggered, and the protrusions 4 and grooves 5 cannot cooperate when the docking direction is wrong, which can effectively prevent mistakes; fourth, the protrusions 4 and grooves 5 on the connection part A and the connection part B are staggered, and the sealing path is more complicated, which can form a labyrinth seal and have a better sealing effect; fifth, at each layer of sealing, the protrusion 4 is inserted into the groove 5 to squeeze the seal 6, and the seal 6 forms a three-sided seal with the bottom surface and two side surfaces of the groove 5 on the outside, and forms a three-sided seal with the bottom surface and two side surfaces of the protrusion 4 on the inside, ensuring enough sealing contact surfaces and improving the sealing effect. In addition, the pressure-bearing sealing surfaces of the module units can be pre-welded into a whole. Since a single module unit is a splicing unit of a sealed pressurized cabin, the size does not need to be designed to be particularly large, and pre-welding will not delay transportation.

[0039] Among them, the number of matching pairs of protrusions 4 and grooves 5 can be determined according to actual needs and effects. In the present embodiment, each docking end face adopts two pairs of protrusions 4 and grooves 5. Compared with one pair of protrusions 4 and grooves 5, the sealing effect is better. Compared with three or more pairs of protrusions 4 and grooves 5, the size of the docking end face can be reduced, and the increase in manufacturing cost and assembly difficulty can be avoided.

[0040] Among them, in order to achieve fast connection, such as Figure 3 As shown, in this embodiment, a flange 2 is provided on the connecting end surface of the connecting portion, and adjacent module units are butt-connected through the flange 2 and the connecting piece, and through holes 1 for matching the connecting piece are distributed along the flange 2. In order to facilitate installation and wiring, preferably, as Figure 1As shown in a), the flanges 22 at both ends lift the module unit, which can provide installation and operation space for connectors on the one hand, and facilitate the subsequent routing of electrical cables, optical cables, water pipes, etc. on the other hand.

[0041] Among them, in order to ensure the sealing effect of the joint and facilitate docking, in this embodiment, the seal 6 has a cavity, and the size of the groove 5 is larger than the size of the protrusion 4 and the seal 6. Therefore: first, when the protrusion 4 compresses the elastic seal 6, the cavity can provide a certain degree of deformation, and the gas inside the cavity can provide a certain degree of rebound, so that the elastic seal 6 is closer to the inner wall of the groove 5 and the outer surface of the protrusion 4, forming a surface seal, thereby ensuring the sealing effect of the joint; second, the size of the groove 5 is slightly larger than the size of the protrusion 4 and the elastic seal 6. On the one hand, the protrusion 4 has a small-sized displacement redundancy in the groove 5, which makes it easier for the protrusion 4 and the groove 5 to dock when the adjacent module units are longitudinally spliced, avoiding docking failure caused by manufacturing and installation errors. On the other hand, a certain space is provided for the deformation of the seal 6 so that it can fit more closely.

[0042] and: like Figure 5 As shown in FIG. 1 , it is an embodiment of the groove 5 and the seal 6, wherein the cross-sections of the groove 5, the protrusion 4 and the seal 6 are rectangular, and there is a gap between the seal 6 and both sides of the groove 5 when the seal 6 is not squeezed, and the width of the protrusion 4 is narrower than the width of the seal 6; therefore: when the protrusion 4 extends into the groove 5 and squeezes the seal 6 to deform, as shown in FIG. Figure 4 As shown, the bottom of the seal 6 is in contact with the bottom of the groove 5, and the two sides of the seal 6 are bent and in contact with the two sides of the groove 5. This arrangement is simple to process.

[0043] like Fig.12 As shown, it is the second embodiment of the groove 5 and the seal 6, wherein the bottom of the groove 5 adopts an inwardly concave arc surface, and the bottom of the seal 6 adopts an outwardly convex arc surface matching the arc surface of the bottom of the groove 5. The seal 6 fits with both sides of the groove 5 in an unextruded state, and an exhaust channel 9 is provided on the outer ring side of the groove 5; therefore: the exhaust channel 9 ensures that the seal 6 can be smoothly installed in the groove 5 and fit with the three sides of the groove 5. When the protrusion 4 extends into the groove 5 to squeeze the seal 6 to deform, since the seal 6 has no movable gap at the bottom, its upper part will shrink inward after being compressed and increase the internal pressure, so it will be closer to the bottom of the groove 5, and the arc-shaped bottom contact will concentrate the pressure on the protruding area at the bottom of the arc surface, further ensuring the seal.

[0044] like Fig.13As shown, it is the third embodiment of the groove 5 and the seal 6, wherein the bottom of the groove 5 adopts an outwardly convex arc surface, and the bottom of the seal 6 adopts an inwardly concave arc surface matching the arc surface of the bottom of the groove 5. The seal 6 fits with both sides of the groove 5 in an unextruded state, and an exhaust channel 9 is provided on the outer ring side of the groove 5; therefore: the exhaust channel 9 ensures that the seal 6 can be smoothly installed in the groove 5 and fit with the three sides of the groove 5. When the protrusion 4 extends into the groove 5 to squeeze the seal 6 and deform it, since the seal 6 has no movable gap at the bottom, its upper part will shrink inward after being compressed and increase the internal pressure, so it will be closer to the bottom of the groove 5, and the arc-shaped bottom contact will concentrate the pressure on the protruding area at the top of the arc surface, further ensuring the seal.

[0045] The sealing effects of the groove 5 and the sealing member 6 in the second and first embodiments are better than those in the first embodiment, but the manufacturing cost will increase.

[0046] Embodiment 2 This embodiment discloses a second type of module unit, such as Figure 1 b), based on the basic model of the first embodiment, an extension strip 3 is added to one side of the top thereof for cooperating with the connector to realize horizontal splicing, and through holes 1 for cooperating with the connector are distributed along the extension strip 3. The extension strip 3 is small in size, convenient for transportation, storage and installation, and can be pre-installed or installed after it is in place. Since the extension strip 3 is only used for connection and does not need to consider the load-bearing and sealing issues, it can be set only on the top without being arranged in a whole circle, and it is easier to install if it is only set on the top.

[0047] Embodiment 3 This embodiment discloses a third type of module unit, such as Figure 1 c), based on the basic model of the first embodiment, the top two sides thereof are added with extension strips 3 for cooperating with the connector to realize horizontal splicing, and through holes 1 for cooperating with the connector are distributed along the extension strips 3. The extension strips 3 are small in size, convenient for transportation, storage and installation, and can be pre-installed or installed after they are in place. Since the extension strips 3 are only used for connection, and the load-bearing and sealing issues do not need to be considered, they can be only set at the top, and do not need to be arranged in a whole circle. Moreover, if they are only set at the top, they are easier to install.

[0048] Among the above three types of modular units, the modular units of embodiment 1 can only be spliced ​​longitudinally, the modular units of embodiment 2 can be spliced ​​longitudinally and transversely on one side, and the modular units of embodiment 3 can be spliced ​​longitudinally and transversely on both sides. The type and quantity of modular units to be invested can be selected according to the specific form of the sealed pressurized cabin. Of course, for absolute versatility, all modular units of embodiment 3 can be used, but this will also cause waste of materials and construction.

[0049] like Figure 4As shown, the connecting piece adopts a combination of studs 7 and nuts 8, and the studs 7 pass through the through holes 1 on both sides and are locked by nuts 8 on both sides. Of course, the connecting piece can also adopt a combination of bolts and nuts 8, and the bolts pass through the through holes 1 on both sides and are locked by nuts 8 on one side.

[0050] Embodiment 4 This embodiment discloses a modular sealed pressurized single cabin body, such as Figures 2 to 5 As shown, three module units of the above-mentioned embodiment 1 are longitudinally spliced ​​together (the module units of embodiment 2 and embodiment 3 can also be used, but there will be waste of materials and construction); the ends of the cabin body are additionally provided with pressure-bearing sealing surfaces for closure, and pressure-bearing doors and windows are additionally provided on the pressure-bearing sealing surfaces at the required positions; the interior thereof can be through-connected, or partitions can be provided to divide different functional areas.

[0051] Embodiment 5 This embodiment discloses a second assembled sealed pressurized single cabin body, such as Figure 6 As shown, two module units of the first embodiment are longitudinally spliced ​​together (module units in the second and third embodiments may also be used, but there will be waste of materials and construction). Embodiment 4 and embodiment 5 respectively disclose that three and two module units are longitudinally spliced ​​to form a single cabin body. In fact, the number of module units in a single cabin body can be set as needed and is not limited.

[0052] The process of installing a single-cabin hull is: according to the size and transportation capacity of the single-cabin hull, the single-cabin hull is selected to be spliced, partially spliced, or transported to the site in a completely unspliced ​​state; when splicing, first put the seal 6 into the groove 5, insert the protrusion 4 into the corresponding groove 5, and then connect the flanges 2 on both sides and lock them with the connecting piece through the through hole 1; after splicing, add a pressure-bearing sealing surface closure at the end, and set a pressure-bearing door and window on the pressure-bearing sealing surface at the required position, or add a pressure-bearing sealing surface closure to the corresponding module unit in advance, and set a pressure-bearing door and window on the pressure-bearing sealing surface at the required position; after splicing, partitions can be set inside according to the needs of different functions, such as setting a transition area, a bathroom area, a living area, etc., wherein each type of area occupies more than one module unit, and the specific number of module units occupied is set according to actual needs, or partitions may not be set to keep the interior connected as a large activity space.

[0053] Embodiment 6 This embodiment discloses a modular sealed pressurized multi-cabin cabin, such as Figure 7As shown: the module units of Example 2 are spliced ​​longitudinally and transversely (the module units of Example 3 can also be used, but there will be waste of materials and construction), in a 2*2 form (3 columns longitudinally and 3 rows transversely); the ends of the cabin are additionally provided with pressure-bearing sealing surfaces for closure, and pressure-bearing doors and windows are additionally provided on the pressure-bearing sealing surfaces at the required positions; the longitudinal internal space of the same column can be connected, or partitions can be set to divide different functional areas.

[0054] Embodiment 7 This embodiment discloses a second assembled sealed pressurized multi-chamber cabin body, such as Figure 8 As shown: the module units in Example 2 and Example 3 are spliced ​​longitudinally and transversely (all the module units in Example 3 can also be used, but there will be waste of materials and construction), in a 3*2 form (3 columns longitudinally and 2 rows transversely); the ends of the cabin body are additionally provided with pressure-bearing sealing surfaces for closure, and pressure-bearing doors and windows are additionally provided on the pressure-bearing sealing surfaces at the required positions; the longitudinal internal space in the same column can be connected, or partitions can be set to divide different functional areas.

[0055] Embodiment 8 This embodiment discloses a third assembled sealed pressurized multi-cabin cabin body, such as Fig. 9 and Fig.10 As shown: the module units in Example 2 and Example 3 are spliced ​​longitudinally and transversely (all the module units in Example 3 can also be used, but there will be waste of materials and construction), in a 3*3 form (3 columns longitudinally and 3 rows transversely); the ends of the cabin body are additionally provided with pressure-bearing sealing surfaces for closure, and pressure-bearing doors and windows are additionally provided on the pressure-bearing sealing surfaces at the required positions; the longitudinal internal space in the same column can be connected, or partitions can be set to divide different functional areas.

[0056] Embodiment 9 This embodiment discloses a fourth assembled sealed pressurized multi-cabin cabin body, such as Fig.11 As shown: the module units in Example 1, Example 2 and Example 3 are spliced ​​longitudinally and transversely (wherein, the module units in Example 1 can also be replaced by the module units in Example 2 or Example 3, and the module units in Example 2 can also be replaced by the module units in Example 3, but there will be waste of materials and construction), there are 3 columns in the longitudinal direction, the first column has 3 module units, the second column has 2 module units, and the third column has 1 module unit; the ends of the cabins are additionally provided with pressure-bearing sealing surfaces for closure, and pressure-bearing doors and windows are additionally provided on the pressure-bearing sealing surfaces at the required positions; the internal space in the same column in the longitudinal direction can be connected, or partitions can be set to divide different functional areas.

[0057] Embodiments 6 to 9 disclose various regular and irregular multi-cabin bodies. Since the multi-cabin bodies can be freely expanded longitudinally and transversely, the specific form of the multi-cabin bodies is based on the actual design and is not limited. Among them, the module units that do not participate in the transverse splicing can be used without, with one side or with both sides of the expansion strip 3, the module units that are transversely spliced ​​on only one side can be used with one side or with both sides of the expansion strip 3, and the module units that are transversely spliced ​​on both sides can only be used with both sides of the expansion strip 3. In order to avoid material and construction waste, the module units that do not participate in the transverse splicing are preferably not equipped with expansion strips 3, and the module units that are transversely spliced ​​on only one side are preferably equipped with expansion strips 3 on one side.

[0058] The process of installing the multi-cabin cabin body is as follows: according to the size and transportation capacity of the multi-cabin cabin body, the multi-cabin cabin body is partially spliced, or transported to the site in a completely unspliced ​​state; when splicing longitudinally, the sealing member 6 is first placed in the groove 5, the protrusion 4 is inserted into the corresponding groove 5, and then the flanges 2 on both sides are butted and locked through the through hole 1 with the matching connector; when splicing transversely, the extension strips 3 on both sides are butted and locked through the through hole 1 with the matching connector; a row of longitudinal module units can be spliced ​​first, and then the remaining rows of module units can be spliced ​​in sequence, or a row of transverse module units can be spliced ​​first, and then the remaining module units can be spliced ​​longitudinally after the current module unit; After splicing, pressure-bearing sealing surface closures are added to the ends, and pressure-bearing doors and windows are set on the pressure-bearing sealing surfaces at the required positions. Pressure-bearing sealing surface closures can also be added to the corresponding module units in advance, and pressure-bearing doors and windows can be set on the pressure-bearing sealing surfaces at the required positions. After splicing, partitions can be set inside the same longitudinal column according to the needs of different functions, such as setting up transition areas, bathroom areas, living areas, etc., wherein each type of area occupies more than one module unit, and the specific number of module units occupied is set according to actual needs. Partitions can also be not set inside the same longitudinal column, and the interior can be kept connected to serve as a large activity space.

[0059] In the single-cabin cabin and the multi-cabin cabin: the single-cabin cabin adopts a longitudinal splicing structure, whose transverse width is fixed and the longitudinal length can be set according to actual needs; the multi-cabin cabin adopts a longitudinal and transverse splicing structure, whose transverse width and longitudinal length can be set according to actual needs; both can be assembled on-site in any place. The key is - first, the two realize weldless splicing and ensure the sealing after splicing, thus solving the problems of transportation restrictions and indoor welding, and can meet the requirements of large volume and random combination, and can restore the main indoor environmental indicators in high-altitude areas to those in plain areas; second, both are spliced ​​by basic module units, which reduces customization costs, cancels connecting modules and transition modules, reduces the pressure-bearing sealing walls of connecting modules and transition modules, requires less steel, and has lower costs, which is conducive to product promotion.

[0060] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
