Description

Technical Field

[0001] This application relates to the field of double-height room combined protection technology, and in particular to a protective structure combining a civil defense basement with a partially double-height room. Background Technology

[0002] In the process of developing and utilizing underground space, the structural design of civil defense basements, as an important infrastructure, has always received much attention. Traditional civil defense basement structures generally adopt the construction methods of integral casting or prefabricated components. This integrated construction method can indeed ensure the integrity and strength of the structure, providing a solid protective barrier for underground space. However, with the acceleration of urbanization and the diversification of underground space utilization needs, the limitations of traditional structures are gradually becoming apparent when dealing with complex terrain and changing usage requirements.

[0003] Especially in situations where it is necessary to set up rooms with double the floor height in certain areas to meet specific functional requirements (such as equipment rooms, storage rooms, etc.), the design of traditional structures often faces challenges. Since the exterior walls of the civil defense basement and the exterior walls of the double-height rooms are independent of each other, and the backfill area between the two requires special treatment, it is necessary to ensure the stability of the overall structure while taking into account the flexibility and usage needs of the local space during the construction process.

[0004] Traditional methods typically involve directly backfilling and compacting soil. However, due to the large backfill area and irregular shape, it is often difficult to achieve completely uniform compaction, resulting in inconsistent soil density within the backfill layer. This uneven density not only affects the overall stability of the backfill layer but may also lead to safety hazards such as settlement and cracking, threatening the long-term safety and performance of the structure. Therefore, this patent requires an upgrade and modification based on existing technology. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a protective structure that combines a civil defense basement with a partially double-height room. This structure overcomes the deficiencies of existing technologies and aims to solve the problem that, due to the large backfill area and irregular shape, it is often difficult to achieve completely uniform compaction, resulting in uneven soil density in the backfill layer. This uneven density not only affects the overall stability of the backfill layer but may also cause safety hazards such as settlement and cracking, threatening the long-term safety and performance of the structure.

[0006] To achieve the above objectives, this application provides the following technical solution: a protective structure combining a civil defense basement with a partially double-height room, comprising walls and a partition layer. The walls are provided with two sets to isolate the double-height room in the civil defense basement. The ends of the two sets of walls are fixedly connected to a connecting wall. A sliding rod is fixedly connected to one side of the connecting wall. The partition layer is slidably connected to the outside of the sliding rod. Rollers are rotatably connected to the top of both sides of the partition layer. Rollers are provided on the outside of the rollers. The bottom of the rollers is attached to the top of the wall. A connecting wheel is fixedly connected to the outside of the rollers. The inner side of the connecting wheel is fixedly attached to the outside of the wall.

[0007] By adopting the above technical solution, during the backfilling process between the two sets of walls, a separator layer is used to divide the gap inside the wall into small areas for backfilling. Soil is then filled into these small areas and compacted. After compaction, rollers roll on top of the wall, causing the separator layer to move outward along the sliding rod. After the separator layer moves outward to a certain extent, some space will be left on one side of the filled area, which will then be filled with soil again. After the soil is filled, it is compacted again, and this process is repeated until the entire area is filled and compacted, thus ensuring good stability of the backfilled soil layer inside the filled area.

[0008] As a preferred technical solution of this application, the partition layer includes a partition base plate and a control layer, wherein the control layer is mounted on top of the partition base plate.

[0009] By adopting the above technical solution, in which the partition base plate is made of cast concrete or a rigid board structure, when the last backfilling is carried out, the control layer is removed from the top of the partition base plate, and then the soil is directly filled into the remaining area, completely covering the partition base plate, and then compacted.

[0010] As a preferred technical solution of this application, a fixing bolt is fixedly connected to the top of the partition base plate, and a fixing nut is threaded to the outside of the fixing bolt after passing through the control layer. A washer is sleeved on the outside of the fixing bolt, and the washer is located between the control layer and the partition base plate.

[0011] By adopting the above technical solution, the partition base plate and the control layer are fixed together by fixing nuts. When the backfilling area is about to be completed, the control layer can be removed from the top of the partition base plate by unscrewing the fixing nuts from the outside of the fixing bolts.

[0012] As a preferred technical solution of this application, a connecting block is fixedly connected to the outer side of the control layer.

[0013] By adopting the above technical solution, multiple connecting blocks are respectively set at each corner of the control layer, and a cover plate is fastened to the outside of the control layer. By screwing bolts into the connecting blocks, the cover plate is fixed to the outside of the control layer, preventing the filling soil from entering the control layer.

[0014] As a preferred technical solution of this application, the roller is fixedly connected to a second helical gear at the middle position of the control layer, the bottom of the second helical gear is meshed with a first helical gear, the first helical gear is fixedly connected to a drive shaft, and the drive shaft is rotatably connected to the outside of the control layer.

[0015] By adopting the above technical solution, the rotation of the drive shaft drives the outer first helical gear to rotate. The first helical gear and the second helical gear are interlocked. During the rotation of the first helical gear, the top interlocked second helical gear can be driven to rotate in the lateral position, thereby driving the roller to rotate, thus realizing the movement of the partition layer inside the wall.

[0016] As a preferred technical solution of this application, the drive shaft is provided with a square connecting hole inside, a square connecting block is inserted into the square connecting hole, and a wheel is fixedly connected to the outside of the square connecting block.

[0017] By adopting the above technical solution, the square connecting block is inserted into the square connecting hole, and then the rotating wheel is manually rotated, thereby driving the square connecting block to rotate. The square connecting block then drives the drive shaft to rotate, and the movement of the partition layer inside the wall can be controlled by the rotation of the drive shaft.

[0018] As a preferred technical solution of this application, the connecting wheel has a circular groove inside, a connecting fixing layer is fixedly connected inside the circular groove, and a connecting nut is threadedly connected to the outside of the connecting fixing layer.

[0019] By adopting the above technical solution, the connecting wheel is slidably connected to the outside of the roller. After the connecting wheel is mounted on the top of the wall, the side of the connecting wheel is pushed to fit against the outside of the wall, so that the roller fits against the top of the wall. Then, the connecting nut is rotated to fix the connecting fixing layer and the roller, thereby ensuring that the roller can drive the connecting wheel to rotate during the rotation process, thereby driving the partition layer to move inside the wall.

[0020] As a preferred technical solution of this application, the slide bar is provided with multiple sets respectively arranged on the inner side of the connecting wall.

[0021] By adopting the above technical solution, the sliding rod can ensure that the partition layer can move stably inside the wall. At the same time, after the wall is filled, the sliding rod can provide good stability to the internal filling layer, improve the overall strength and shear resistance of the filling layer, resist the shear deformation caused by external loads, and prevent the filling layer from being damaged.

[0022] The beneficial effects of this application are:

[0023] 1. In this utility model, by dividing a large backfill area into multiple small areas and backfilling and compacting layer by layer, the compaction of the backfill soil layer is ensured. Each small area can be fully compacted during backfilling, avoiding the problem of uneven compaction caused by excessive backfill area, thereby significantly improving the stability of the overall backfill soil layer.

[0024] 2. In this utility model, the sliding rod, which serves as the sliding track for the partition layer, not only provides support for the movement of the partition layer, but also enhances the overall shear resistance of the filling layer through its robust structure. The design of the rollers and connecting wheels further reduces the frictional resistance of the partition layer during the sliding process, enabling the partition layer to move smoothly and steadily, and avoiding the impact of shear force generated during the movement on the structural stability.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Reference Figure 1-5 A protective structure combining a civil defense basement with a partially double-height room includes a wall 1 and a partition layer 4. The wall 1 has two sets of partitions, each isolating a double-height room in the civil defense basement. Connecting walls 2 are fixedly connected to the ends of the two sets of walls 1. Backfill material is filled into the gap between the two sets of walls 1. A sliding rod 3 is fixedly connected to one side of the connecting wall 1. The partition layer 4 is slidably connected to the outside of the sliding rod 3. Rollers 6 are rotatably connected to the top of both sides of the partition layer 4. Rollers 7 are installed on the outside of the rollers 6, with their bottoms fitting against the top of the wall 1. Connecting wheels 8 are fixedly connected to the outside of the rollers 7, with their inner sides fixedly fitting against the outside of the wall 1. The backfill material is filled into the gap between the two sets of walls 1. During the process of filling the gaps in the wall 1, the internal gaps of the wall 1 are divided into small areas for filling soil by the partition layer 4. Soil is filled into the small areas formed by the partition layer 4, and then the soil in these small areas is compacted. After the compaction is completed, the partition layer 4 is moved outward along the slide bar 3 by the roller 7 rolling on the top of the wall 1. After the partition layer 4 has moved outward to a certain extent, some space will be left on one side of the filled area, and then soil will be filled into the interior again. After the soil is filled, it will be compacted again. This process is repeated until the entire area is filled and compacted, thus ensuring that the backfilled soil layer inside the filled area has good stability.

[0033] In this embodiment, as Figure 1 - Figure 5 As shown, the partition layer 4 includes a partition base plate 401 and a control layer 402. The control layer 402 is erected on top of the partition base plate 401. The partition base plate 401 is a concrete casting or a rigid board structure. When the last backfilling is carried out, the control layer 402 is removed from the top of the partition base plate 401, and then the soil is directly filled into the remaining area, completely covering the partition base plate 401, and then compacted.

[0034] In this embodiment, as Figure 1 - Figure 5As shown, a fixing bolt 403 is fixedly connected to the top of the partition base plate 401. The fixing bolt 403 passes through the control layer 402 and is threaded with a fixing nut 405 on its outer side. A washer 404 is sleeved on the outer side of the fixing bolt 403. The washer 404 is located between the control layer 402 and the partition base plate 401. The partition base plate 401 and the control layer 402 are fixed together by the fixing nut 405. When the backfilling area is about to be completed, the control layer 402 can be removed from the top of the partition base plate 401 by unscrewing the fixing nut 405 from the outside of the fixing bolt 403.

[0035] In this embodiment, as Figure 1 - Figure 5 As shown, a connecting block 406 is fixedly connected to the outer side of the control layer 402. Multiple connecting blocks 406 are respectively set at each corner of the control layer 402. A cover plate is fastened to the outer side of the control layer 402. By screwing bolts into the connecting block 406, the cover plate is fixed to the outer side of the control layer 402 to prevent soil from entering the control layer 402.

[0036] In this embodiment, as Figure 1 - Figure 5 As shown, a second helical gear 601 is fixedly connected to the roller 6 at the middle position of the control layer 402. A first helical gear 408 is meshed with the bottom of the second helical gear 601. A drive shaft 407 is fixedly connected inside the first helical gear 408. The drive shaft 407 is rotatably connected to the outside of the control layer 402. The rotation of the drive shaft 407 drives the outer first helical gear 408 to rotate. The first helical gear 408 and the second helical gear 601 are interleaved. During the rotation of the first helical gear 408, it can drive the top interleaved second helical gear 601 to rotate in the lateral position, thereby driving the roller 7 to rotate, thus realizing the movement of the partition layer 4 inside the wall 1.

[0037] In this embodiment, as Figure 1 - Figure 5 As shown, the drive shaft 407 has a square connecting hole 409 inside, and a square connecting block 501 is inserted into the square connecting hole 409. A rotating wheel 5 is fixedly connected to the outside of the square connecting block 501. The square connecting block 501 is inserted into the square connecting hole 409, and then the rotating wheel 5 is manually rotated, thereby driving the square connecting block 501 to rotate. The square connecting block 501 then drives the drive shaft 407 to rotate. The movement of the partition layer 4 inside the wall 1 can be controlled by the rotation of the drive shaft 407.

[0038] In this embodiment, as Figure 1 - Figure 5As shown, the connecting wheel 8 has a circular groove 801 inside, and a connecting fixing layer 802 is fixedly connected inside the circular groove 801. A connecting nut 803 is threadedly connected to the outside of the connecting fixing layer 802. The connecting wheel 8 is slidably connected to the outside of the roller 6. When the connecting wheel 8 is mounted on the top of the wall 1, the side of the connecting wheel 8 is pushed to fit against the outside of the wall 1, so that the roller 7 fits against the top of the wall 1. Then, by rotating the connecting nut 803, the connecting fixing layer 802 is tightened with the roller 6, thereby ensuring that the roller 6 can drive the connecting wheel 8 to rotate during the rotation process, thereby driving the partition layer 4 to move inside the wall 1.

[0039] In this embodiment, as Figure 1 - Figure 5 As shown, the sliding rod 3 has multiple sets respectively set inside the connecting wall 2. The sliding rod 3 can ensure that the partition layer 4 can move stably inside the wall 1. At the same time, after the wall 1 is filled, the sliding rod 3 can provide good stability to the internal filling layer, improve the overall strength and shear resistance of the filling layer, resist the shear deformation caused by external loads, and prevent the filling layer from being damaged.

[0040] Working principle: First, construct two sets of walls 1, ensuring that walls 1 are vertical and stable. At the ends of the two sets of walls 1, construct connecting walls 2, which should be firmly connected to walls 1 to form a stable structural frame. On the inner side of connecting walls 2, install multiple sets of sliding rods 3, which should be vertical and parallel to walls 1 to ensure that the partition layer 4 can slide smoothly. The control layer 402 is erected on top of the partition base plate 401. Fixing bolts 403 are installed on the top of the partition base plate 401, and after passing through the control layer 402, fixing nuts 405 and washers are installed on the outer side. 404. Backfill the soil layer into the gap between the two sets of walls 1. First, backfill the small area formed by the partition layer 4 and compact it layer by layer to ensure the compactness of the backfill soil layer. After the small area is backfilled and compacted, manually rotate the rotating wheel 5 to drive the drive shaft 407 to rotate. Then, through the meshing of the first helical gear 408 and the second helical gear 601, the roller 7 rotates, thereby driving the partition layer 4 to move outward along the sliding rod 3. After the partition layer 4 has moved out of a certain area, the empty area is backfilled and compacted again. Repeat the above steps until the entire area is filled and compacted. After most of the area is backfilled and compacted, remove the control layer 402 from the top of the partition base plate 401. Then, directly fill the remaining area with soil and completely cover the partition base plate 401. Finally, compact it.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
