Description

Technical Field

[0001] This utility model specifically relates to a rear support fence for the base of an air-supported membrane structure, belonging to the field of building technology. Background Technology

[0002] Air-supported membrane structures (SMS) are buildings where a prefabricated membrane structure is fixed to the perimeter of a foundation retaining wall. An automated air supply system inflates the structure, typically achieving a positive pressure of around 200 Pa. This pressure difference stabilizes the membrane structure, allowing it to withstand external wind, rain, and snow loads. Because no beams or columns are required for support, SMS structures offer maximum usable space. They are lightweight, convenient, flexible, detachable, and offer high space utilization, making them suitable for various applications, particularly in sports stadiums, leisure venues, and warehousing and freight facilities. While SMS structures use a membrane material as their outer shell, supported by the pressure difference between the inside and outside, their inherent strength can suffer over time. A major drawback is their over-reliance on air pressure for support, as SMS structures primarily depend on this pressure difference to maintain their shape and stability. Therefore, once the air pressure system malfunctions or the external environment, such as strong winds or heavy rain, has a significant impact on the air pressure, there is a risk of overall structural instability. Currently, the corresponding protective measures are limited to using existing fencing structures at a certain distance around the air-supported structure, or combining them with fixed-structure fencing. These types of fencing cannot be moved or dismantled according to changes in needs, and there are no corresponding protective measures that can adapt to the air-supported structure itself to cope with sudden weather changes or other emergency needs. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a post-support fence for the root of an air-supported structure is provided to solve the above problems.

[0004] A rear support fence for the root of an air-supported membrane structure is disclosed. The root support fence is a straight support fence, comprising a main protective plate, an inner filling bag, and an outer filling box. The main protective plate is a square plate, which is vertically installed outside the retaining wall foundation of the air-supported membrane structure. The bottom of the main protective plate on the side facing the air-supported membrane structure is in close contact with the outer wall of the retaining wall foundation. An inner filling bag is provided on the side of the main protective plate facing the air-supported membrane structure. The inner filling bag moves back and forth along the height direction of the main protective plate, and the bottom of the inner filling bag is in close contact with the top of the retaining wall foundation of the air-supported membrane structure. The outer filling box is located at the bottom of the outer side of the main protective plate. Both the inner filling bag and the outer filling box are filled with counterweights.

[0005] As a preferred embodiment: the inner filling bag is a concave shovel-shaped filling bag, which includes an inner support piece, an outer backing piece, a flexible bottom piece, and two corrugated side pieces. The outer wall of the inner support piece is slidably connected to the main protective plate. The outer backing piece is disposed on the side of the inner support piece facing the air-supported structure. The two ends of the outer backing piece are respectively connected to the two ends of the inner support piece through the two corrugated side pieces. The outer side of the outer backing piece is a flexible side that is concave towards the inner support piece. The flexible bottom piece is disposed at the bottom of the inner support piece and the outer backing piece. A first deformable filling cavity is formed between the inner wall of the inner support piece, the inner wall of the outer backing piece, the top surface of the flexible bottom piece, and the inner walls of the two corrugated side pieces. A first inlet and outlet that matches the first deformable filling cavity is formed between the top side of the inner support piece, the top side of the outer backing piece, and the top side of the two corrugated side pieces. When the corrugated side pieces are in an extended state, the thickness of the first deformable filling cavity is in an expanded state. When the corrugated side pieces are in a shortened state, the thickness of the first deformable filling cavity is in a narrowed state.

[0006] As a preferred embodiment: at least two pull-back control rods are provided between the inner support plate and the outer abutment plate. Each pull-back control rod includes a limiting cover, a post, a main rod body, and a limiting sleeve. The limiting cover is a circular piece. The limiting cover, the post, and the main rod body are coaxially connected in sequence. The post is inserted into the outer abutment plate. One end of the post is fixedly connected to the limiting cover, and the other end is fixedly connected to one end of the main rod body. The other end of the main rod body passes through the inner support plate and the main protective plate in sequence and is detachably connected to the limiting sleeve.

[0007] As a preferred option, the counterweight is a block of soil.

[0008] As a preferred option, the outer filling box is replaced with a folded bag.

[0009] A rear support fence for the root of an air-supported structure is disclosed. The root support fence is a corner support fence, which includes a main protective plate, an inner filling bag, and two outer filling boxes. The main protective plate is an L-shaped plate and is vertically installed at the corner of the retaining wall foundation in the air-supported structure. The bottom of the main protective plate on the side facing the air-supported structure is in close contact with the outer wall of the retaining wall foundation. An inner filling bag is provided on the side of the main protective plate facing the air-supported structure, and the bottom of the inner filling bag is in close contact with the top of the retaining wall foundation in the air-supported structure. Two outer filling boxes are respectively provided on the bottom of the outer wall of the main protective plate. Each inner filling bag and each outer filling box is filled with a counterweight.

[0010] As a preferred embodiment: the main protective plate includes two component plates, both of which are vertically arranged. One side of one component plate is hinged to one side of the other component plate, and an outer filling box is provided at the bottom of the outer wall of each component plate.

[0011] As a preferred embodiment: the inner filling bag is a triangular concave filling bag, comprising two inner support pieces, an outer backing piece, a flexible bottom piece, and two corrugated side pieces. The outer walls of the inner support pieces are set on the main protective plate, and the two inner support pieces are hinged together. Each inner support piece has a corresponding corrugated side piece on its outer side, and the outer side of each inner support piece is connected to one side of its corresponding corrugated side piece. The other sides of the two corrugated side pieces are respectively connected to both sides of the outer backing piece. The outer side of the outer backing piece is a flexible side that faces the concavity of the inner support piece. The flexible substrate is placed at the bottom of the inner support sheet and the outer abutment sheet. A second deformable filling cavity is formed between the inner wall of the outer abutment sheet, the top surface of the flexible substrate, the inner walls of the two inner support sheets, and the inner walls of the two corrugated side sheets. A second inlet and outlet that matches the second deformable filling cavity is formed between the top side of each inner support sheet, the top side of the outer abutment sheet, and the top side of the two corrugated side sheets. When the corrugated side sheets are in an extended state, the thickness of the second deformable filling cavity is in a widened state. When the corrugated side sheets are in a shortened state, the thickness of the second deformable filling cavity is in a narrowed state.

[0012] As a preferred embodiment: a pull-back control rod is provided between each inner support piece and the outer backing piece. The pull-back control rod includes a limiting cover, a post, a main rod body, and a limiting sleeve. The limiting cover is a circular piece. The limiting cover, the post, and the main rod body are coaxially connected in sequence. The post is inserted into the outer backing piece. One end of the post is fixedly connected to the limiting cover, and the other end is fixedly connected to one end of the main rod body. The other end of the main rod body passes through its corresponding inner support piece and main protective plate in sequence and is detachably connected to the limiting sleeve.

[0013] The beneficial effects of this utility model are as follows:

[0014] The root support fence of this utility model has two structural forms, namely, straight support fence and corner support fence, depending on the location of its use around the air-supported structure.

[0015] When the root support fence is a straight support fence, the main protective plate, inner filling bag and outer filling box cooperate to form bottom protection for the outer side or outer end of the air-supported membrane structure, improving the wind resistance performance of the side or end of the retaining wall foundation over long distances. It can be arranged at the corresponding position of the air-supported membrane structure according to temporary emergencies or emergency situations. The main protective plate, inner filling bag and outer filling box are matched with the root structure of the air-supported membrane structure to form a counterweight pressing structure with multi-directional close connection. It can also control the position of the counterweight, forming a stable and tight connection on the retaining wall foundation of the air-supported membrane structure, and a close but not tight connection on the air membrane part of the air-supported membrane structure. This improves the protection strength while reducing the impact on the air-supported membrane structure, which is conducive to improving the stability performance of the air-supported membrane structure under secondary weight-adding configuration. This utility model can realize the partial or overall configuration process as needed.

[0016] When the root support fence is a corner support fence, it forms a bottom protection for the corner of the air-supported membrane structure by combining the main protective plate structure itself, the inner filling bag, and the two outer filling boxes, thereby improving the wind resistance performance of the corner of the retaining wall foundation. The corner support fence is closely attached to the retaining wall foundation of the air-supported membrane structure, and is close to but not touching the air-supported membrane part of the structure. The corner support fence can be reconfigured at the corner of the air-supported membrane structure for secondary reinforcement protection in case of temporary emergencies or emergency situations. This utility model is particularly suitable for the circumferential partial or overall support of large air-supported membrane structures. Attached Figure Description

The main protective plate 1 is an existing enclosure structure with a grid or equidistant gaps, and its shape is square, i.e., a square plate. The main protective plate 1 is vertically installed outside the retaining wall foundation 11 in the air-supported structure 10. The bottom of the main protective plate 1 on the side closest to the air-supported structure 10 is flush with the retaining wall foundation. The outer wall of the main protective plate 1 is tightly attached to the main protective plate 1. An inner filling bag 2 is provided on the side of the main protective plate 1 facing the air-supported membrane structure 10. The inner filling bag 2 moves back and forth along the height direction of the main protective plate 1. The bottom of the inner filling bag 2 is attached to the top of the retaining wall foundation 11 in the air-supported membrane structure 10. The outer filling box 8 is set at the bottom of the outer side of the main protective plate 1. Both the inner filling bag 2 and the outer filling box 8 are filled with counterweight 3. The counterweight 3 is soil or other counterweight structure that can be filled to form a counterweight effect. After the soil is filled into the counterweight 3, a counterweight structure is formed.

[0030] In this embodiment, the height of the main protective plate 1 can be between 1.5 and 2.5 meters. Alternatively, the main protective plate 1 can be heightened according to the specific needs of severe weather.

[0033] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One, combined with... Figure 2 As shown, in this embodiment, the bottom of the straight support fence can also be connected to the retaining wall foundation 11 through multiple connecting bolts 12, thereby increasing the bottom fixing strength of this utility model during use. The connecting bolts 12 are inserted between the outer filling box 8, the main protective plate 1 and the retaining wall foundation 11 to improve the connection strength between the three. The connecting bolts 12 can be added as needed for connection. When the connecting bolts 12 are provided, after the connecting bolts 12 are inserted and connected, the soil is filled into the outer filling box 8 to form the counterweight 3.

[0034] Specific Implementation Method Three: This implementation method is a further limitation of Specific Implementation Method One or Two, combined with... Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, two sliders 9-2 are arranged side by side on the inner filling bag 2. The inner wall of the main protective plate 1 facing the air membrane building 10 is machined with grooves 9-1 that correspond one-to-one with the sliders 9-2. The sliders 9-2 and the grooves 9-1 slide in a one-to-one correspondence. The length direction of the grooves 9-1 is in the same direction as the height direction of the main protective plate 1. With the cooperation of the two sliders 9-2, the inner filling bag 2 slides vertically until the bottom of the inner filling bag 2 is stably attached to the retaining wall foundation 11.

[0035] Furthermore, the slider 9-2 has a T-shaped longitudinal cross-section along its thickness direction, and the shape of the groove 9-1 is matched with that of the slider 9-2. The groove 9-1 is a T-shaped groove that is narrow on the outside and wide on the inside. The horizontal end of the T-shaped slider slides in cooperation with the groove 9-1, and the vertical end of the T-shaped slider is fixedly connected to the outer wall of the inner filling bag 2.

[0036] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Methods One, Two, or Three. In this implementation method, the shape of the inner filling bag 2 is adapted to the shape of the air-supported membrane structure 10, specifically a concave shovel-shaped filling bag. The inner filling bag 2 includes an inner support piece 2-1, an outer abutment piece 2-2, a flexible bottom piece 2-3, and two corrugated side pieces 2-4. The outer wall of the inner support piece 2-1 is slidably connected to the main protective plate 1. The outer abutment piece 2-2 is disposed on the side of the inner support piece 2-1 facing the air-supported membrane structure 10. The two ends of the outer abutment piece 2-2 are respectively connected to the two ends of the inner support piece 2-1 through the two corrugated side pieces 2-4. The outer side of the outer abutment piece 2-2 is a flexible side that is concave towards the inner support piece 2-1. The flexible bottom piece 2-3 is disposed between the inner support piece 2-1 and the outer abutment piece 2-2. At the bottom, a first deformable filling cavity 5 is formed between the inner wall of the inner support piece 2-1, the inner wall of the outer abutment piece 2-2, the top surface of the flexible bottom piece 2-3, and the inner walls of the two corrugated side pieces 2-4. A first inlet and outlet that cooperates with the first deformable filling cavity 5 is formed between the top side of the inner support piece 2-1, the top side of the outer abutment piece 2-2, and the top side of the two corrugated side pieces 2-4. When the corrugated side pieces 2-4 are in an extended state, the thickness of the first deformable filling cavity 5 is in a widened state. When the corrugated side pieces 2-4 are in a shortened state, the thickness of the first deformable filling cavity 5 is in a narrowed state. The deformation of the first deformable filling cavity 5 is conducive to forming a shielding structure with different counterweights. The specific counterweight weight can be determined according to the specific architectural design data of the air-supported membrane building 10 and the corresponding counterweight design requirements.

[0037] In this embodiment, the specific outer diameter of the main rod 4-3 can be appropriately configured according to the volume of the first deformation filling cavity 5, depending on the specific design requirements.

[0038] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3, or 4. In this implementation method, at least two pull-back control rods 4 are provided between the inner support plate 2-1 and the outer abutment plate 2-2. Each pull-back control rod 4 includes a limiting cover plate 4-1, an insert post 4-2, a main rod body 4-3, and a limiting sleeve 4-4. The limiting cover plate 4-1 is a circular plate. The limiting cover plate 4-1, the insert post 4-2, and the main rod body 4-3 are coaxially connected in sequence. The insert post 4-2 is inserted on the outer abutment plate 2-2. One end of the insert post 4-2 is fixedly connected to the limiting cover plate 4-1, and the other end of the insert post 4-2 is fixedly connected to one end of the main rod body 4-3. The other end of the main rod body 4-3 passes through the inner support plate 2-1 and the main protective plate 1 in sequence and is detachably connected to the limiting sleeve 4-4.

[0039] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five, combined with... Figure 1 and Figure 2As shown, in this embodiment, the outer filling box 8 is a box structure with an open top, and the outer filling box 8 is replaced by a folding bag body 6. The folding bag body 6 is easy to fold, which is beneficial for stacking and storing multiple of this utility model, and also makes it easy to adjust the opening and closing range of the top opening. The folding bag body 6 includes a flexible bag body 6-1 and two hinged connecting rods 6-2. The flexible bag body 6-1 is a square bag body with an open top. The flexible bag body 6-1 can be an existing woven bag, geotextile bag or other sealed flexible bag body. A hinged connecting rod 6-2 is provided on each side of the flexible bag body 6-1. The hinged connecting rod 6-2 is a cross-shaped connecting rod assembly, including two component rods. The middle of the two component rods are hinged together, and the end of each component rod is hinged to the outer wall of the flexible bag body 6-1.

[0040] Specific implementation method seven: Combining Figure 9 and Figure 10 This embodiment describes a corner support fence, which is used at the corner of the retaining wall foundation 11 in the air-supported structure 10. The corner support fence includes a main protective plate 1, an inner filling bag 2, and two outer filling boxes 8. The main protective plate 1 is an L-shaped plate, which is vertically installed at the corner of the retaining wall foundation 11 in the air-supported structure 10. The bottom of the side of the main protective plate 1 closest to the air-supported structure 10 is in close contact with the outer wall of the retaining wall foundation 11. An inner filling bag 2 is provided on the side of the main protective plate 1 facing the air-supported structure 10, and the bottom of the inner filling bag 2 is in close contact with the top of the retaining wall foundation 11 in the air-supported structure 10. Two outer filling boxes 8 are respectively provided on the bottom of the outer wall of the main protective plate 1. Each inner filling bag 2 and each outer filling box 8 is filled with a counterweight 3.

[0041] In this embodiment, the bottom of the corner support fence can also be connected to the retaining wall foundation 11 by multiple connecting bolts 12, thereby increasing the bottom fixing strength of this utility model during use. The connecting bolts 12 are inserted between the outer filling box 8, the main protective plate 1 and the retaining wall foundation 11 to improve the connection strength between the three. The connecting bolts 12 can be added as needed for connection. When the connecting bolts 12 are installed, after the connecting bolts 12 are connected, the soil is filled into the outer filling box 8 to form the counterweight 3.

[0042] In this embodiment, the main protective plate 1 includes two component plates 1-1, both of which are vertically arranged. One side of one component plate 1-1 is hinged to one side of the other component plate 1-1. An outer filling box 8 is correspondingly provided at the bottom of the outer wall of each component plate 1-1. The two component plates 1-1 can be integrally stamped, and the connection point between them is made of plastic or other flexible material, allowing adjustment of the rotation angle of the two component plates 1-1. A hinge can also be configured to allow for rotational adjustment of the adaptation angle between the two components.

[0043] In this embodiment, the inner filling bag 2 is a triangular concave filling bag. The inner filling bag 2 includes two inner support pieces 2-1, an outer abutment piece 2-2, a flexible bottom piece 2-3, and two corrugated side pieces 2-4. The outer wall of the inner support piece 2-1 is set on the main protective plate 1. The two inner support pieces 2-1 are hinged together. Each inner support piece 2-1 has a corresponding corrugated side piece 2-4 on its outer side. The outer side of each inner support piece 2-1 is connected to one side of its corresponding corrugated side piece 2-4. The other sides of the two corrugated side pieces 2-4 are respectively connected to the two sides of the outer abutment piece 2-2. The outer side of the outer abutment piece 2-2 is a flexible side that faces the concavity of the inner support piece 2-1. A flexible base sheet 2-3 is disposed at the bottom of the inner support sheet 2-1 and the outer abutment sheet 2-2. A second deformable filling cavity 7 is formed between the inner wall of the outer abutment sheet 2-2, the top surface of the flexible base sheet 2-3, the inner walls of the two inner support sheets 2-1, and the inner walls of the two corrugated side sheets 2-4. A second inlet and outlet that cooperates with the second deformable filling cavity 7 is formed between the top side of each inner support sheet 2-1, the top side of the outer abutment sheet 2-2, and the top side of the two corrugated side sheets 2-4. When the corrugated side sheet 2-4 is in an extended state, the thickness of the second deformable filling cavity 7 is in an expanded state. When the corrugated side sheet 2-4 is in a shortened state, the thickness of the second deformable filling cavity 7 is in a narrowed state.

[0044] In this embodiment, the corrugated side panels 2-4 are flexible corrugated sheets in the form of an accordion structure. They are fan-shaped and can be folded to form variations in the unfolding range. The folding principle is the same as the expansion and contraction principle of existing corrugated sheets.

[0045] In this embodiment, a pull-back control rod 4 is provided between each inner support piece 2-1 and the outer abutment piece 2-2. The pull-back control rod 4 includes a limiting cover 4-1, a post 4-2, a main rod body 4-3, and a limiting sleeve 4-4. The limiting cover 4-1 is a circular piece. The limiting cover 4-1, the post 4-2, and the main rod body 4-3 are coaxially connected in sequence. The post 4-2 is inserted on the outer abutment piece 2-2. One end of the post 4-2 is fixedly connected to the limiting cover 4-1, and the other end of the post 4-2 is fixedly connected to one end of the main rod body 4-3. The other end of the main rod body 4-3 passes through its corresponding inner support piece 2-1 and the main protective plate 1 in sequence and is detachably connected to the limiting sleeve 4-4.

[0046] In this embodiment, the main rod body 4-3 has an external thread at one end near the limiting sleeve 4-4, and the limiting sleeve 4-4 is a nut, which is used to lock the two together on the outer wall of the main protective plate 1 through threaded engagement.

[0047] In this embodiment, the specific outer diameter of the main rod 4-3 can be appropriately configured according to the volume of the second deformation filling cavity 7, depending on the specific design requirements.

[0048] In this embodiment, the main protective plate 1 can also be machined with elongated holes. The length direction of the elongated holes is the same as the length direction of the main protective plate 1, and their size matches the outer diameter of the main rod 4-3, so that the pull-back control rod 4 is set in a one-to-one correspondence. The machining of the elongated holes facilitates the synchronous lifting and lowering movement of the main rod 4-3 in conjunction with the inner filling bag 2.

[0049] Furthermore, the width of the elongated hole is smaller than the outer diameter of the limiting sleeve 4-4, which facilitates the stable contact of the limiting sleeve 4-4 with the main protective plate 1.

[0050] In this embodiment, the working process of the pull-back control rod 4 is as follows: the outer pad 2-2 is processed with through holes. When the main rod 4-3 is pulled back, the limiting cover 4-1 is fixed on the outer wall of the outer pad 2-2 to form a stable connection between the main rod 4-3 and the outer pad 2-2. By pulling back the main rod 4-3, the gap between the top of the inner support piece 2-1 and the top of the outer pad 2-2 is reduced, so that the outer pad 2-2 can cooperate to enclose the soil while also separating from the air film position of the air film structure 10 to form a gap fit. When the main rod 4-3 is pulled back to the predetermined position, the limiting sleeve 4-4 is fitted on the main rod 4-3 to realize the limiting sleeve 4-4, the inner support piece 2-1 and the main protective plate 1 cooperate to complete the limiting effect on the end of the main rod 4-3, and realize the process of fixing the end of the main rod 4-3, thereby limiting the opening and closing posture of the inner filling bag 2 to be stable and immobile. Structures and connection methods not mentioned in this embodiment are the same as those in specific embodiments one, two, five, or six.

[0051] Furthermore, the outer support plate 2-2 can also be fitted against the outer wall of the air-supported membrane structure 10 according to the architectural design requirements, ensuring that the pressure of the counterweight formed by this utility model on the contact position of the outer wall of the air-supported membrane is within the bearing pressure range of the air-supported membrane structure 10. By pulling back the main rod 4-3, the gap between the top of the inner support plate 2-1 and the top of the outer support plate 2-2 is reduced, until the outer support plate 2-2 can not only surround the soil, but also be fitted against the air-supported membrane position of the air-supported membrane structure 10, forming a protective effect on the root structure position of the air-supported membrane structure 10.

[0052] In this embodiment, the specific arrangement and connection relationship between the outer bonding piece 2-2 and the outer wall of the air-supported membrane structure 10 depends on the specific weather conditions and the architectural design requirements of the air-supported membrane structure 10 itself.

[0053] Specific implementation method eight: Combination Figures 1 to 10This embodiment describes a root protection system for an inflatable membrane structure. The system comprises a root support fence, specifically including multiple straight support fences and four corner support fences. The four corner support fences are respectively installed at the four corners of the retaining wall foundation 11 in the inflatable membrane structure 10. Multiple straight support fences are arranged side-by-side between each pair of adjacent corner support fences along the length and / or width direction of the retaining wall foundation 11 in the inflatable membrane structure 10. The sides of adjacent straight support fences are either close together or spaced apart, depending on the specific design requirements. The sides of the straight support fences and the sides of the corner support fences are also either close together or spaced apart, depending on the specific design requirements.

[0054] Each vertical support fence includes a main protective plate 1, an inner filling bag 2, and an outer filling box 8. The main protective plate 1 is a square plate and is vertically installed outside the retaining wall foundation 11 in the air-supported membrane structure 10.

An inner filling bag 2 is provided on the side of the main protective plate 1 facing the air-supported membrane structure 10. The inner filling bag 2 moves back and forth along the height direction of the main protective plate 1. The bottom of the inner filling bag 2 is in close contact with the top of the retaining wall foundation 11 in the air-supported membrane structure 10. The outer filling box 8 is located at the bottom of the outer side of the main protective plate 1. Both the inner filling bag 2 and the outer filling box 8 are filled with counterweights 3.

[0055] Each corner support fence includes a main protective plate 1, an inner filling bag 2, and two outer filling boxes 8. The main protective plate 1 is an L-shaped plate and is vertically installed at the corner of the retaining wall foundation 11 in the air-supported membrane structure 10. The bottom of the main protective plate 1 on the side closest to the air-supported membrane structure 10 is in close contact with the outer wall of the retaining wall foundation 11. An inner filling bag 2 is provided on the side of the main protective plate 1 facing the air-supported membrane structure 10. The bottom of the inner filling bag 2 is in close contact with the top of the retaining wall foundation 11 in the air-supported membrane structure 10.

Each inner filling bag 2 and each outer filling box 8 is filled with a counterweight 3.

[0056] The air-supported membrane structure 10 mentioned in this embodiment is an existing air-supported membrane structure. The retaining wall foundation 11 is an important component of existing air-supported membrane structures, used to provide circumferential foundation support for the air-supported membrane structure 10. Structures and connection methods not mentioned in this embodiment are the same as in specific embodiments one, two, five, six, or seven.

[0057] Specific Implementation Method Nine: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, Six, Seven or Eight. The cooperation method of two adjacent straight support fences is tight, gap or detachable connection. When detachable connection is used, connecting ears can be configured on the main protective plate 1 and detachably connected by bolts.

[0058] Similarly, the corner support fence and its adjacent straight support fence can be connected by being close together, with gaps, or detachably. When detachably connected, connecting ears can be configured on the main protective plate 1 and the connection can be detachably made by bolts.

[0059] Working principle:

[0060] Based on design requirements, emergency situations, or other needs, determine whether the protected location of the air-supported membrane structure 10 is a partial or overall location. Configure an appropriate number of straight support fences and corner support fences according to the required protection length. The process for arranging each straight support fence is as follows: attach the main protective plate 1 to the outside of the retaining wall foundation 11 within the air-supported membrane structure 10, ensuring that the bottom of the side of the main protective plate 1 closest to the air-supported membrane structure 10 is tightly against the outer wall of the retaining wall foundation 11. Adjust the inner filling bag 2 on the side of the main protective plate 1 facing the air-supported membrane structure 10 until the bottom of the inner filling bag 2 is tightly against the top of the retaining wall foundation 11 within the air-supported membrane structure 10. When the outer wall of the outer backing piece 2-2 is configured to fit the air membrane gap in the air-supported structure 10 according to relevant requirements, the pull-back control rod 4 is adjusted to ensure that the outer wall of the outer backing piece 2-2 in the inner filling bag 2 fits the air membrane gap in the air-supported structure 10. Then, soil is filled into the outer filling box 8 to form a counterweight 3. After filling the soil, the pull-back control rod 4 is adjusted again. The outward movement of the pull-back control rod 4 causes the outer backing piece 2-2 to move outward, ensuring that the outer wall of the outer backing piece 2-2 in the inner filling bag 2 fits the air membrane gap in the air-supported structure 10. This not only provides protection and shielding but also presses it firmly onto the retaining wall foundation 11. Similarly, soil is filled into the outer filling box 8 to form another counterweight 3.
