[0002] With the introduction of the national dual carbon strategy, traditional cement-based materials have been subject to increasingly stringent restrictions due to their high carbon emissions. Furthermore, in polar regions and other low-temperature environments, the use of traditional concrete materials faces many challenges due to their slow solidification rate, susceptibility to cracking, and poor resistance to freeze-thaw cycles. Their application in extreme environments is greatly restricted. Furthermore, traditional concrete materials are difficult to construct, and their repair and demolition processes are complex. The large amount of waste generated during the process is also difficult to effectively handle, which puts tremendous pressure on the environment. These problems have limited the application of traditional concrete materials in green and sustainable construction, making them unable to meet the requirements of modern architecture for low-carbon, environmentally friendly, and efficient construction.

The surfaces are all coated with a super corrosion-resistant coating. Connecting pieces are used to align several brick structure hollow condensation steel pipes 113 to provide overall strength.

[0046] The interlocking bonding unit 112 is a stainless - steel metal component that fits the shape of the precast ice - concrete building structure unit 111.

[0055] S3. Prepare an ice - based composite gelling material (proportion: fresh water: NaCl: Na2SO4 = 90%: 7%: 3%) and mix it evenly with ethylene glycol according to the mix ratio to obtain a mixed solution. Pour the mixed solution into the small - sized ice - concrete mold until the mixed solution is flush with the surface of the small - sized ice - concrete mold and starts to overflow, then stop adding the mixed solution.

[0056] S4. Move the small ice-concrete mold to a low-temperature environment to achieve the freezing process of the internal solution. After a precast ice-concrete building structure unit 111 with a certain strength is formed, remove the mold, take it out, and transport it to the polar construction site.

[0057] S5. Clean the polar construction area, stack the precast ice-concrete building structure units 111 into a building structure wall with dimensions of 5m * 0.25m * 3m according to the specification requirements, and fully connect and seal the pipelines between the precast ice-concrete building structure units 111 through the connectors between the brick-built structure hollow condensation steel pipes 113 and the interlocking bonding unit 112.

[0058] S6. At the same time, embed temperature sensors 203 and strain sensors 204 inside the wall and connect them to the intelligent detection platform 201.

[0059] S7. After the wall construction is completed, connect the pipeline interface to the local temperature control device 202, and continuously pass a cooling medium into the brick-built structure hollow condensation steel pipes 113 inside to achieve the long-term freezing and hardening without melting of the ice-concrete building part 10.

[0060] S8. The central intelligent monitoring unit 20 conducts real-time monitoring and control of the temperature and strain of the ice-concrete building part 10 and adjusts the transported cooling medium to conduct intelligent control of the ice-concrete building part 10.

[0083] Functions and effects of the embodiments

[0084] According to the ice-concrete building system and its rapid construction method involved in the present invention, the present invention uses ice-concrete materials as building materials, providing an innovative solution for the construction of ice-concrete buildings in polar or low-temperature environments. The building structure is erected through ice-concrete materials. The preparation process does not require high-temperature calcination, greatly reducing carbon dioxide emissions and meeting the development requirements of green and low-carbon. Through the solidification of ice-concrete materials, a stable building structure is formed, and the temperature at specific positions of the building structure is precisely controlled to achieve local melting and solidification of the structure. This enhances the flexibility of the structure, significantly simplifies the repair and demolition processes of the building structure, making the operation more convenient and efficient, reducing the complexity of construction and maintenance, improving the utilization and sustainability of building materials. A central intelligent monitoring system is adopted in the building structure to monitor the overall state of the ice-concrete building in real time and conduct fixed-point regulation of key parts. This ensures the stability and safety of the building structure during long-term use, can effectively prevent the occurrence of potential problems, and improves the service life and durability of the building. These characteristics make ice-concrete buildings show important application value and practical significance in actual applications, providing strong support for addressing low-temperature building challenges and promoting the development of green buildings, and demonstrating broad application prospects.

[0085] The present invention uses ice-concrete materials as building materials, replacing the setting and hardening process of traditional cement with the solidification process of water to form a building structure with strength. Compared with the production of cement materials, the preparation of ice-concrete materials does not require high-temperature calcination, greatly reducing carbon dioxide emissions and meeting the development requirements of green and low-carbon.

[0086] The curing speed of the ice-concrete materials used in the present invention is faster than that of traditional concrete, and it has good plastic shaping ability, enabling the formation of the building structure to be completed in a shorter time. Combined with the rapid construction method of the present invention, its construction process is more simple and fast, which can significantly improve construction efficiency. In temporary buildings or extreme weather environments, it can be quickly erected and meet basic usage requirements, saving a large amount of time and labor.

[0087] The present invention forms a stable building structure through the solidification of ice-concrete materials, and precisely controls the temperature at specific positions of the building structure to achieve local melting and solidification of the structure. This enhances the flexibility of the structure, significantly simplifies the repair and demolition processes of the building structure, making the operation more convenient and efficient, reducing the complexity of construction and maintenance, and improving the utilization and sustainability of building materials.

[0088] The present invention adopts a central intelligent monitoring system in the building structure to monitor the overall state of the ice concrete building in real time and perform fixed-point regulation on key parts. Through precise data collection and analysis, this system ensures the stability and safety of the building structure during long-term use, can effectively prevent the occurrence of potential problems, and improves the service life and durability of the building.

[0089] The present invention significantly improves its mechanical properties such as compressive strength and flexural strength by optimizing the mix ratio and structural design of the ice concrete material. At the same time, technical means such as steel reinforcement and external insulation are introduced to further enhance the stability and safety of the building. This enables the ice concrete building to maintain excellent service performance in polar or other low-temperature environments, meet long-term use requirements, and ensure the durability and reliability of the structure.
