[0053] S2. Weigh all kinds of raw materials according to the mixing ratio of ice concrete material 130 shown in Table 1, mix the crushed stone, sea sand and polyethylene fiber evenly, and then fill them evenly into small ice concrete molds and continuously vibrate them.

[0054] S3. Prepare an ice-based composite cementitious material (ratio of fresh water: NaCl: Na2SO4 = 90%: 7%: 3%) and mix it evenly with ethylene glycol according to the mixing ratio to obtain a mixed solution. Pour the mixed solution into a small ice-based concrete mold until the mixed solution is level with the surface of the small ice-based concrete mold and begins to overflow. Stop adding the mixed solution.

[0055] S4. The small ice concrete mold is moved into a low-temperature environment to achieve the freezing process of the internal solution. After the precast ice concrete building structure unit 111 with a certain strength is formed, the mold is removed and transported to the polar construction site.

[0056] S5. Clean up the polar construction area, stack the precast ice concrete building structure unit 111 into a building structure wall of 5m*0.25m*3m according to the specifications, and fully connect and seal the pipes between the precast ice concrete building structure unit 111 with the interlocking adhesive unit 112 through the connector between the brick-built hollow condensing steel pipe 113.

[0057] S6. At the same time, a temperature sensor 203 and a strain sensor 204 are embedded inside the wall and connected to the intelligent detection platform 201.

[0058] S7. After the wall construction is completed, the pipe interface is connected to the local temperature control device 202. Cooling medium is continuously introduced into the hollow condensing steel pipe 113 of the internal brick structure to achieve long-term freezing hardening and non-melting of the ice concrete building part 10.

[0059] S8, the central intelligent monitoring unit 20 monitors and controls the temperature and strain of the concrete building unit 10 in real time and adjusts the cooling medium to intelligently regulate the concrete building unit 10.

The steel reinforcement support frame 121 includes horizontally arranged support steel bars 123 and vertically arranged integral cast-in-place hollow condensing steel pipes 124.

The supporting steel bar 123 and the integral cast-in-place hollow condensing steel pipe 124 are connected by a 2mm diameter binding steel wire to form a steel bar support frame 121. Temperature sensor 203 and strain sensor 204 are embedded in the frame and connected to the intelligent detection platform 201.

[0071] S3. Weigh all kinds of raw materials according to the mixing ratio of the concrete material 130 shown in Table 2, mix the artificial crushed stone and cellulose fiber thoroughly, and then fill them evenly into the building formwork 125 and continuously vibrate them.

[0072] S4. Prepare ice-based composite cementitious material (ratio of fresh water: K2SO4: Na2CO3 = 95%: 4%: 1%) and mix it evenly with ethylene glycol according to the mixing ratio to obtain a mixed solution. Pour the mixed solution into the building template 125 until the mixed solution is level with the surface of the building template 125 and begins to overflow, then stop adding the mixed solution.

[0073] S5, connect the interface of the integral cast-in-place hollow condensing steel pipe 124 to the local temperature control device 202, and realize the freezing process of the solution in the building formwork 125 by introducing cooling medium into the integral cast-in-place hollow condensing steel pipe 124, thereby forming a condensed concrete material filling layer 122 with a certain strength.

[0074] S6. After the overall cast-in-place structure 120 has cooled down, the formwork is removed. The local temperature control device 202 continuously introduces cooling medium into the hollow condensing steel pipe 124 of the internal overall cast-in-place structure to achieve long-term freezing and hardening of the ice concrete building part 10 without melting.

[0085] The ice-curing concrete material used in this invention cures faster than traditional concrete and possesses better shaping ability, allowing for the formation of building structures in a shorter time. Combined with the rapid construction method of this invention, the construction process is simpler and faster, significantly improving construction efficiency.
