Description

Technical Field

[0001] The utility model belongs to the technical field of underground support structures, and in particular relates to an inflatable underground support structure. Background Art

[0002] The function of an underground support structure is generally to create a certain space underground for the storage of personnel or objects or to serve as a protective shelter. Currently, the construction forms that can be used as underground support structures generally include cast concrete, high-strength steel plate support, and earthen kilns. However, when used as temporary storage or defensive shelters, these structures are difficult to construct and slow to build, failing to meet the required convenience and speed. In particular, as the load-bearing requirements and underground space increase, the difficulty and speed of construction will increase significantly. Furthermore, once formed, they cannot be disassembled for secondary use. Therefore, it is essential to design an underground support structure that can be quickly and easily constructed for temporary storage and rapid combat defensive shelters. Utility Model Content

[0016] 2. Compared with traditional hard building materials or frame structures, the inflatable underground support structure can be quickly deployed through a simple inflation process, saving a lot of manpower and material costs, and is particularly suitable for rapid response in emergency situations;

[0017] 3. By setting different numbers and positions of air ribs, the shape and size of the structure can be adjusted according to actual needs, which improves the flexibility of structural design;

[0018] 4. The air ribs are inserted into the column feet on the ground fabric, and combined with the ground support design, the stability of the overall structure is enhanced, and good stability can be maintained even in adverse weather conditions;

[0019] 5. The Velcro design of the front door makes it easier for people to enter and exit, while the vents help maintain internal air circulation and improve safety;

[0020] 6. By setting up wire holes and light cord fixing belts, the structure can not only be used as a temporary living space, but also for various purposes such as temporary office and medical rescue point;

[0021] 7. If there is an inner tent on the inside of the tarpaulin, the comfort of the internal environment can be further improved and the impact of the external environment can be reduced;

[0022] 8. All components can be replaced or repaired individually, reducing long-term maintenance costs;

[0023] To sum up, the utility model adopts inflatable high-pressure air ribs as load-bearing units. Multiple high-pressure air ribs are closely arranged to form a high-bearing capacity underground support structure, which can bear soil of more than 1-2m. After the soil is filled, it is the same as the surrounding environment and does not affect the normal passage of personnel, vehicles, etc.; at the same time, in order to better apply to the field of combat protection shelters, or to separate underground spaces, this structure can also be provided with an inflatable door, which can perform impact protection in the field of combat protection shelters and can be used as a partition door in fields such as underground storage.
