Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an attosecond device building. Background Technology

[0002] An attosecond is the shortest time scale that humans can currently observe; one attosecond is only one ten-hundred-billionth of a second. Using attosecond laser pulses, scientists can track, measure, and manipulate the motion of electrons, much like watching a movie in slow motion—essentially capturing the "moving images" of electrons with a "high-speed camera." Attosecond devices are ultrashort pulse laser facilities used to observe the ultrafast motion of electrons within atoms. Attosecond devices utilize attosecond-level light pulses (1 attosecond = 10⁻¹). 8 It can observe the movement of electrons inside atoms (in seconds) and capture the dynamic processes of microscopic phenomena such as quantum properties, chemical reactions, and material phase transitions, which is equivalent to a "super-high-speed camera" for the microscopic world.

[0003] The experimental building for an attosecond device cannot be built like a regular experimental building. It needs to support the attosecond device itself while also housing auxiliary equipment such as air conditioning rooms and vacuum pump rooms. These devices generate significant noise and vibration during operation, affecting the experimental accuracy of the attosecond device. Therefore, the building structure must be designed to ensure the stability of precision instruments (such as scanning electron microscopes and transmission electron microscopes) in complex environments, allowing the attosecond device to maintain its performance even under conditions of intense vibration. This is the core focus of the building design.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation 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.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1 like Figures 1 to 11 As shown, this application provides an attosecond device building, including: a raft slab 1, a base 2, a frame structure 3, a vibration source device 4, and a roof 5. The experimental device is mounted on the raft slab 1. The base 2 is located around the periphery of the raft slab 1, and is isolated from the raft slab 1. The frame structure 3 is mounted on the base 2. The vibration source device 4 is mounted on the base 2 and / or the frame structure 3. The roof 5 is located on top of the raft slab 1 and the experimental device, and is connected to the frame structure 3. In this attosecond device building, the raft slab 1 is located in the middle, the base 2 and the frame structure 3 are located around its periphery, the vibration source device 4 is mounted on the base 2 and / or the frame structure 3, isolated from the raft slab 1 in the middle, and the roof 5 is mounted on the frame structure 3, with the load transferred to the base 2. When the vibration source device 4 is working, the vibration will not be transmitted to the raft plate 1, which helps the experimental equipment to meet the VC-E anti-micro-vibration standard, ensures the stability of the precision experimental equipment, and enables the experimental equipment to maintain its performance under complex vibration conditions, meeting the requirements of high-precision experimental scenarios in the laboratory.

[0024] In some possible implementations, such as Figure 4 As shown, the attosecond device building includes a retaining wall 6, which extends along the periphery of the raft slab 1. A vibration isolation trench is formed between the retaining wall 6 and the raft slab 1. The base 2 and the raft slab 1 are respectively located on both sides of the vibration isolation trench, which is filled with a sand layer a. The sand layer a isolates the base 2 and the raft slab 1. The sand layer a serves to insulate against noise and reduce vibration, preventing vibration waves generated by the vibration source device 4 from being transmitted from the base 2 to the raft slab 1 during operation.

[0025] Considering that the outer area of ​​the vibration isolation trench needs to be backfilled with soil in the early stage, and that sand layer a needs to be kept dry, construction can only proceed after the roof 5 is completed. Roof 5 covers the top of the vibration isolation trench to prevent rainwater from entering the trench and causing water to seep into sand layer a, thus affecting the vibration isolation effect. Therefore, before backfilling and during the construction of frame structure 3, airbags need to be installed in the vibration isolation trench. The airbags are supported on the inner side of retaining wall 6 as temporary supports to protect retaining wall 6 from deformation and prevent excessive stress on one side of the retaining wall due to backfilling on the other side, which would affect the structural stability of the retaining wall.

[0026] In some possible implementations, such as Figure 4 As shown, the retaining wall 6 includes a foundation beam 61 and a masonry wall 62. The foundation beam 61 and the strip foundation 2 are integrally formed, and the masonry wall 62 is set on the foundation beam 61.

[0027] In this implementation plan, considering the small width of the vibration isolation trench, if the retaining wall 6 is directly cast in place, there will be a problem of limited space for formwork support. In this embodiment, the retaining wall 6 is divided into two parts: a foundation beam 61 and a masonry wall 62. The upper part of the retaining wall 6 is replaced with a masonry wall, which simplifies the construction difficulty.

[0028] In some possible implementations, the frame structure 3 includes frame beams 31 and multiple columns 32, each column 32 being disposed on the strip foundation 2. The columns 32 are arranged sequentially at intervals around the circumference of the raft slab 1. The frame beams 31 are located at the top of each column 32 and connect each column 32. Some columns 32 are provided with corbels, and the periphery of the roof 5 is supported on the corbels of each column 32.

[0029] In some possible implementations, such as Figure 8 As shown, the roof 5 includes a spherical grid 51 and a top cover 52. The spherical grid 51 is supported on the corbels. Multiple spheres 511 are arranged on the spherical grid 51. Vertical keels are arranged on some of the spheres 511. The top cover 52 is supported on the vertical keels and is fixed to the vertical keels.

[0030] In some possible implementations, the attosecond device building also includes an air supply duct 8, a return air duct 9, a roof slab, a smoke exhaust duct, and a fire sprinkler duct, etc., wherein the roof slab is located between the raft slab 1 and the spherical grid 51, and is directly or indirectly connected to the spherical grid 51, forming a top space between the roof slab and the spherical grid 51, and the air supply duct 8 and the return air duct 9 are both partially located within the top space.

[0031] In some possible implementations, the top plate includes a first top plate 10 and a second top plate 20. The first top plate 10 is located at the bottom of the air supply duct 8 and the return air duct 9. The air supply duct 8 is connected to an air outlet, which is connected to the first top plate 10. The first top plate 10 has a clearance opening corresponding to the air outlet, and a filter is installed on either the air outlet or the clearance opening. The second top plate 20 is located below the first top plate 10, and the second top plate 20 has multiple air outlets. By providing multiple air outlets on the second top plate 20, uniform air intake is achieved, reducing the impact on the experimental equipment.

[0032] Optionally, the attosecond device building includes a first conversion layer located below and connected to the spherical grid frame 51. Multiple hangers are installed at the bottom of the first conversion layer to connect the supply air duct 8 and the return air duct 9. Hangers are installed on the supply air duct 8 and / or the return air duct 9 to connect to the first top plate 10. A second top plate 20 is connected to either or both of the first top plate 10 and the spherical grid frame 51. For example, the top of the hanger connecting the second top plate 20 is connected to the first top plate 10, or the top passes through the first top plate 10 and connects to the spherical grid frame 51.

[0033] In some possible implementations, such as Figure 8 As shown, the attosecond device building includes a return air duct 40, which extends longitudinally. One end of the return air duct 40 is connected to the return air pipe 9, and the other end extends to the raft 1.

[0034] In some possible implementations, such as Figure 4 As shown, a pipe trench 121 is provided on the top of the raft 1, which includes a water supply and drainage trench and an electrical trench. The water supply and drainage trench facilitates water supply and drainage within the equipment building and also prevents the pipes 100 from being exposed. The electrical trench facilitates the arrangement of cables connecting experimental equipment and prevents the cables from being exposed.

[0035] Example 2 like Figures 1 to 11 As shown, this embodiment provides an attosecond device building, including: a raft slab 1, a vibration isolation trench, a base 2, a frame structure 3, a vibration source device 4, and a roof 5. The experimental equipment is mounted on top of the raft slab 1, and the thickness of the raft slab 1 is 1.8m to 2.5m. Preferably, the thickness of the raft slab 1 is 2m. The vibration isolation trench is arranged around the edge of the raft slab 1. The base 2 is located outside the vibration isolation trench. The frame structure 3 is disposed on the base 2. The vibration source device 4 is disposed on the base 2 and / or the frame structure 3. The roof 5 is located on top of the raft slab 1 and the experimental equipment, and the roof 5 is connected to the frame structure 3. The vibration source device 4 includes air conditioning equipment, a vacuum pump, and a water pump.

[0036] In this application, the thickness of the raft foundation 1 is 1.8m to 2.5m. This relatively large thickness facilitates the installation of experimental equipment and improves the overall rigidity of the foundation. The greater the thickness of the raft foundation 1, the more significant the pressure dispersion effect on the foundation, which can reduce the risk of building settlement during earthquakes. A thicker raft foundation 1 can disperse vibration waves, preventing a large amount of external vibration waves from being transmitted to the experimental equipment and affecting its operation.

[0037] The attosecond device building of this application features a raft slab 1 in the center, surrounded by strip foundations 2 and a frame structure 3. The vibration source device 4 is mounted on the strip foundations 2 and / or the frame structure 3, isolated from the central raft slab 1. The roof 5 is mounted on the frame structure 3, with the load transferred to the strip foundations 2. When the vibration source device 4 is operating, vibration is not transmitted to the raft slab 1, which helps the experimental equipment meet the VC-E anti-micro-vibration standard, ensuring the stability of the precision experimental equipment. This allows the equipment to maintain its performance under complex vibration conditions, meeting the requirements of high-precision laboratory experimental scenarios.

[0038] In some possible implementations, such as Figure 7 As shown, the attosecond device building includes multiple mounting bases 50, which are set on the base 2. Each vibration source device 4 is respectively mounted on its corresponding mounting base 50. The mounting base 50 provides a mounting position for the vibration source device 4. The vibration waves generated by the operation of the vibration source device 4 are transmitted to the base 2 via the mounting base 50. The base 2 is isolated from the raft 1 and will not affect the normal operation of the experimental equipment.

[0039] In some possible implementations, such as Figure 7 As shown, a sand layer a is provided between the mounting base 50 and the strip base 2. The sand layer a can be coarse sand. The sand layer a can reduce the impact of vibration waves on the strip base 2 on the stability of the raft slab 1.

[0040] In some possible implementations, a concrete slab 60 is provided on the base strip 2, the concrete slab 60 enclosing a cavity, and the mounting base 50 is located within the cavity. A sand layer is provided between the inner wall of the cavity and the outer wall of the mounting base 50. By providing a sand layer a between the mounting base 50 and the base strip 2, the mounting base 50 and the vibration source device 4 on it are further isolated from the base strip 2, reducing the transmission of vibration from the mounting base 50 to the base strip 2, and thus reducing the transmission of vibration from the vibration source device 4 to the raft slab 1.

[0041] In some possible implementations, such as Figure 6 and Figure 7 As shown, the concrete slab 60 includes a bottom plate 610 and a side plate 620. The bottom plate 610 is supported on the raft 1, and the side plate 620 is disposed on the edge of the bottom plate 610. The bottom plate 610 and the side plate 620 enclose the cavity. A sand layer a is disposed between the bottom plate 610 and the mounting base 50, and a sand layer a is disposed between the side plate 620 and the mounting base 50. That is, the bottom wall and the peripheral edge of the mounting base 50 are separated from the concrete slab 610 by the sand layer a, resulting in a significant vibration isolation effect.

[0042] In some possible implementations, such as Figures 5 to 7As shown, the attosecond device building includes an anti-adhesive roll 70 and a concrete pad 80. The anti-adhesive roll 70 covers the sand layer a on top of the base plate 610, the concrete pad 80 is placed on the anti-adhesive roll 70, and the installation foundation 50 is placed on the concrete pad 80.

[0043] The concrete pad 80 helps prevent damage to the bottom sand layer a during the binding of the reinforcing steel bars within the upper installation foundation 50. The reverse-bonded roll 70 forms a protective layer between the installation contact and the sand layer a, isolating the cement slurry from the bottom sand layer a during the pouring of the upper concrete 510. Adding a 1.2mm pre-laid reverse-bonded roll 70 layer plus a 60mm concrete pad 80 on the horizontal sand layer a solves both waterproofing and seepage prevention issues, as well as the protection of the foundation formwork and the sand layer a.

[0044] In some possible implementations, the installation foundation 50 includes foundation reinforcement, concrete 510, and a steel truss plate 520. The steel truss plate 520 is located within the recessed cavity, and a gap exists between the steel truss plate 520 and the side plate 620 for filling with sand layer a. The steel truss plate 520 encloses and forms a casting cavity, with the foundation reinforcement located within the casting cavity and connected to the steel truss plate 520. Concrete 510 is poured into the casting cavity, and the steel truss plate 520 and the concrete 510 are connected to form a single unit. Considering the small distance between the installation foundation 50 and the side plate 620, making it difficult to erect formwork, in this embodiment, a steel truss plate 520 is provided inside the side plate 620 to enclose and form the casting cavity. The steel truss plate 520 consists of a formwork and reinforcement bars set on the formwork; the formwork can be a metal plate. After pouring and solidification, the steel truss plate 520 is not disassembled. The steel truss plate 520 constitutes part of the structure of the installation foundation 50, thereby simplifying the construction structure and improving construction efficiency.

[0045] In some possible implementations, a vibration isolation assembly (not shown) is installed on the mounting base 50, located between the vibration source device 4 and the mounting base 50. That is, the vibration isolation assembly, positioned between the vibration source device and the mounting base 50, directly reduces the transmission of vibration waves from the vibration source device 4 to the mounting base 50, thereby further reducing the transmission of vibration waves to the raft 1. The vibration isolation assembly can be an elastic element such as a spring, which can elastically support the vibration source device and the mounting base 50.

[0046] In some possible implementations, such as Figure 4As shown, the attosecond device building includes a retaining wall 6, which is positioned between the raft foundation 1 and the strip foundation 2. A vibration isolation trench is formed between the retaining wall 6 and the raft foundation 1, isolating the raft foundation 1 and the strip foundation 2. During backfilling of the strip foundation 2 and the frame structure 3, airbags are installed within the vibration isolation trench. These airbags support the side of the retaining wall 6 away from the strip foundation 2. After the backfilling of the strip foundation 2 and the frame structure 3 is completed, and the roof 5 covers the top of the raft foundation 1, a sand layer a is filled within the vibration isolation trench.

[0047] Example 3 like Figure 9 As shown in the figure, this embodiment provides a detailed description of the raft foundation structure, which includes: a first casting body 11, a second casting body 12, and a steel plate 13. The first casting body 11 has a trench body 1211. The second casting body 12 is located on top of the first casting body 11, and the second casting body 12 has a through trench eaves 1212. The trench eaves 1212 and the trench body 1211 are connected to form a complete trench 121. Experimental equipment is installed on the second casting body 12. The steel plate 13 covers the inner wall of the trench eaves 1212 and is connected to the second casting body 12. The height ratio of the first casting body 11 to the height of the second casting body 12 is (8-15):1, and the height of the first casting body 11 is 1.5m to 2.5m.

[0048] The raft slab of this application can be used in clean laboratories, where the flatness and precision requirements of the surface layer and the trench eaves 1212 are high, and aesthetic requirements also exist. In this embodiment, a steel plate 13 is installed on the trench eaves 1212 to strengthen the eaves structure and ensure the final forming quality. The raft slab of this application is poured in two stages, which helps to improve the flatness of the raft slab surface layer and the trench eaves 1212.

[0049] In some possible implementations, the trench eaves 1212 includes a first through groove 12121 and a second through groove 12122. The first through groove 12121 connects to the trench body 1211, and the second through groove 12122 is located on the side of the first through groove 12121 away from the trench body 1211, that is, the second through groove 12122 is located at the top of the first through groove 12121, and the cross-section of the second through groove 12122 is larger than the cross-section of the first through groove 12121. A stepped surface is formed between the first through groove 12121 and the second through groove 12122. A steel plate 13 covers the inner wall of the first through groove 12121, the inner wall of the second through groove 12122 and the stepped surface, respectively. The steel plate 13 is bonded and fixed to the concrete 510 and will not be disassembled later. A flat and beautiful eaves structure can be formed by the steel plate 13.

[0050] The steel plate 13 can be a single piece or it can be formed by splicing multiple plates. The final shape of the steel plate 13 is cylindrical, and its structure and shape are consistent with the size and specifications of the eaves.

[0051] In some possible implementations, the raft slab includes shear reinforcement 13, partially located in the first cast-in-place body 11 and partially located in the second cast-in-place body 12, thereby enhancing the integration of the first and second cast-in-place bodies 11. Alternatively, the shear reinforcement 13 can be pre-embedded in the first cast-in-place body 11 for connection with the second cast-in-place body 12.

[0052] In some possible implementations, the shear reinforcement 13 includes vertical reinforcement segments and horizontal reinforcement segments, the vertical reinforcement segments extending to the first cast-in-place body 11 and the second cast-in-place body 12 respectively, and the horizontal reinforcement segments located within the second cast-in-place body 12 and connecting the tops of several of the vertical reinforcement segments.

[0053] In some possible implementations, the raft foundation includes anchor bars 14 located within the second cast-in-place body 12, which are respectively connected to the steel plate 13 and the shear reinforcement 13. Connecting the steel plate 13 and the shear reinforcement 13 with the anchor bars 14 to form an integral structure improves the installation accuracy of the steel plate 13 and the structural strength of the installation structure.

[0054] In some possible implementations, the anchor bars 14 include first anchor bars 141 and second anchor bars 142, which are arranged sequentially along the height direction of the raft foundation. The first anchor bars 141 connect the steel plate 13 and the horizontal reinforcement segment, respectively, and the second anchor bars 142 connect the steel plate 13 and the vertical reinforcement segment, respectively. Multiple first anchor bars 141 can be provided, with each first anchor bar 141 arranged at intervals along the circumference of the steel plate 13. Similarly, multiple second anchor bars 142 can also be provided, with each second anchor bar 142 arranged at intervals along the circumference of the steel plate 13, thereby stably and reliably fixing the steel plate 13, improving the construction accuracy of the raft foundation trench, and ensuring the shape of the trench eaves.

[0055] In some possible implementations, such as Figure 9As shown, the steel plate 13 includes a top upright plate 131, a bottom upright plate 132, and a horizontal plate 133. The top upright plate 131 covers the inner wall of the first through groove 12121, the bottom upright plate 132 covers the inner wall of the second through groove 12122, and the horizontal plate 133 covers the stepped surface. A first anchoring rib 141 is connected to the angle between the top upright plate 131 and the horizontal plate 133, and a second anchoring rib 142 is connected to the bottom upright plate 132. Adjacent top upright plates 131, bottom upright plates 132, and horizontal plates 133 can be welded together. Alternatively, the top upright plate 131, bottom upright plate 132, and horizontal plate 133 can be a single integrated structure with few or no welds between them.

[0056] In some possible implementations, the raft slab includes pre-embedded pipelines (not shown) located within the second cast-in-place body 12. The ratio of the height of the first cast-in-place body 11 to the height of the second cast-in-place body 12 is (8-15):1, and the height of the first cast-in-place body 11 is 1.5m-2.5m. The height of the second cast-in-place body 12 can be approximately 150mm, and the pipeline 100 is pre-embedded within it. This facilitates control over the straightness and accuracy of the second cast-in-place body 12's structure and also facilitates the installation of the pre-embedded pipelines.

[0057] In some possible implementations, the upper surface of the second casting body 12 has an electron microscope mounting area. The first casting body 11 and the second casting body 12 are both provided with glass fiber reinforced steel bars in the area directly below the electron microscope mounting area. Some experimental equipment, such as electron microscopes, are susceptible to interference from magnetic fields such as iron. In this embodiment, instead of metal steel bars, glass fiber reinforced steel bars are provided in the area directly below the electron microscope mounting area, which can avoid the formation of magnetic fields that interfere with the normal operation of the electron microscope.

[0058] In some possible implementations, steel fibers and crack-resistant fibers can be provided in the second casting body 12, that is, steel fibers and crack-resistant fibers are added to the concrete of the second casting body 12 to ensure that the second casting body 12 (concrete) does not shrink or crack, thereby improving the precision and durability of the raft slab surface layer.

[0059] In some possible implementations, embodiments of this application also provide an attosecond device tower, including the raft plate described above.

[0060] Example 4 Combination Figures 1 to 11As shown in the embodiment of this application, the attosecond device building is further described in detail, comprising: a raft slab 1, a base 2, an installation foundation 50, a pipeline foundation 90, and a pipeline 100. Experimental equipment is mounted on the raft slab. The base 2 is located on the side of the raft slab and is isolated from the raft slab. The installation foundation 50 is mounted on the base 2, and a vibration source device 4 is mounted on the installation foundation 50. A gap exists between the installation foundation 50 and the raft slab 1. The pipeline foundation 90 is located on the installation foundation 50 and is connected to or in contact with the raft slab 1. A sand layer a is provided between the pipeline foundation 90 and the installation foundation 50. The pipeline 100 extends along the pipeline foundation 90, with one end connected to the vibration source device 4 and the other end extending to the raft slab 1.

[0061] This embodiment applies to the mounting base 50 near the raft foundation 1. When the mounting base 50 is close to the raft foundation 1, a pipeline foundation 90 can be set on the mounting base 50, which facilitates the laying of pipelines 100 between the raft foundation 1 and the vibration source device 4. By setting a sand layer a between the pipeline foundation 90 and the mounting base 50, vibration isolation is achieved, avoiding or reducing the transmission of vibrations from the mounting base 50 to the raft foundation.

[0062] In some possible implementations, the mounting base 50 has a groove, a portion of the pipeline base 90 is located within the groove, and a sand layer a is provided between the outer wall of the pipeline base 90 and the inner wall of the groove. The portion of the pipeline base 90 extends out of the groove to the raft slab to facilitate the laying of pipelines 100 between the raft slab and the pipeline base 90.

[0063] In some possible implementations, the mounting base 50 includes a bottom base 530 and a side base 540 connected to the bottom base 530. The side base 540 protrudes from the bottom base 530, and the vibration source device 4 is mounted on the side base 540. A groove is formed between the side base 540 and the bottom base 530. The vibration source device 4 can be easily mounted on the side base 540.

[0064] Accordingly, the pipeline foundation 90 includes a horizontal foundation 910 and a vertical foundation 920 located at one end of the horizontal foundation 910 and vertically connected to the horizontal foundation 910. The horizontal foundation 910 is connected to or in contact with the raft slab. A sand layer a is provided between the horizontal foundation 910 and the bottom foundation 530, and a sand layer a is provided between the vertical foundation 920 and the side foundation 540. The pipeline 100 extends sequentially along the horizontal foundation 910 and the vertical foundation 920.

[0065] In some possible implementations, both the pipeline foundation 90 and the raft are provided with pipe trenches 121, and the pipeline 100 on the pipeline foundation 90 is connected to the pipe trenches 121 on the raft, with the pipeline 100 extending along the pipe trenches 121.

[0066] In some possible implementations, a pipeline support is provided on the pipeline foundation 90, and the pipeline 100 is connected to the pipeline support. The pipeline support can be a vibration-damping support, which is typically elastic and can absorb the vibration of the pipeline 100, avoiding or reducing the transmission of vibration to the raft slab. The vibration-damping support can be directly adopted from the supports provided in the prior art, and this application does not improve the structure of the vibration-damping support.

[0067] Optionally, an elastic buffer structure is provided between the pipeline 100 and the pipeline support, and / or an elastic buffer structure is provided between the pipeline support and the pipeline foundation 90, i.e., the elastic buffer structure is an elastic structure within the vibration damping support. The elastic buffer structure can be a spring, rubber, or other similar structure.

[0068] In some possible implementations, the horizontal foundation 910 and the raft 1 are connected by a flexible structure 930. The flexible structure 930 can be a rubber block or other mechanically elastic structure, sufficient to connect the raft 1 and the horizontal foundation 910. In some possible implementations, a vibration isolation trench is provided between the raft slab 1 and the base 2, isolating the raft slab 1 and the base 2. The vibration isolation trench may be filled with a sand layer a to reduce or prevent the transmission of vibration from the mounting foundation 50 to the raft slab 1.

[0069] A retaining wall 6 can be installed around the perimeter of the raft foundation 1, forming a vibration isolation trench between the retaining wall 6 and the raft foundation 1. The vibration isolation trench isolates the raft foundation 1 from the base 2. The retaining wall 6 can be connected to the base 2, or there can be a gap between the retaining wall 6 and the base 2 to facilitate the installation of a sand layer a, thereby enhancing the vibration isolation effect.

[0070] The horizontal foundation 910 of the pipeline foundation 90 can extend through the retaining wall 6 and has a gap between it and the top of the retaining wall 6. Sand layers a are provided on both sides and the top of the retaining wall 6 to isolate the retaining wall 6 and the horizontal foundation 910 from vibration.

[0071] In some possible implementations, such as Figure 7 As shown, a sand layer a is provided between the mounting base 50 and the strip base 2 to reduce the vibration transmission from the mounting base 50 to the strip base 2.
