[0082] Laying gravel layer: Lay a 5 cm thick layer of gravel with a particle size of 1 to 2 cm to ensure sufficient drainage and bearing capacity.

[0083] Use a compactor to compact the sand and gravel layer to ensure its density and prevent instability of the living cabin due to ground subsidence in the future.

[0084] S2: Installation of support columns Determine the location of the support posts: Determine the installation position of the supporting columns according to the design drawings, and mark the specific position of each column on the sand and gravel layer.

[0085] Use a tape measure and marking tools to ensure that each support post is spaced and positioned as designed.

[0086] Support column installation: Erect the support posts and place them vertically at the marked locations.

[0087] Use bolts of M12 to M16 specifications for fixing and connection. Each supporting column needs to be fastened with 4 bolts to ensure the firmness and verticality of the supporting column.

[0088] During the fixing process, use a level to correct the verticality of the supporting column, and use temporary supporting tools when necessary to ensure that the column does not tilt during the installation process.

[0093] S4: Galvanized sheet laying Galvanized sheet laying: Galvanized sheets with a thickness of 1.0 to 2.0 mm are laid on the base frame to form a protective layer on the bottom to enhance the durability and corrosion resistance of the bottom structure.

[0094] Place the galvanized sheets on the base frame manually or mechanically, ensuring that there is at least 5 cm overlap between each sheet to prevent dust and moisture penetration.

[0095] Fixing galvanized sheet: Use M8 stainless steel screws to fix the galvanized sheet to the base frame. Use at least 8 to 10 screws to fix each galvanized sheet to ensure that it is firmly fixed and does not shift.

[0096] Use an electric screwdriver to tighten the screws, making sure the screw heads are flush with the board surface and do not protrude to prevent impact on the superstructure.

[0097] S5: Plywood laying Laying of plywood: Plywood is laid on the galvanized sheet with a thickness of 10 to 20 mm. The plywood is used to improve the bearing capacity and comfort of the ground.

[0098] Lay the plywood evenly on the galvanized sheet, ensuring that each piece of plywood is tightly spliced ​​together and the seam does not exceed 2 mm.

[0099] Plywood fixing: Use adhesive to bond the plywood to the galvanized sheet. The adhesive is environmentally friendly and the coating amount is controlled at 200 to 300 grams per square meter.

[0100] After the adhesive is applied, use an electric screwdriver to fix the plywood to the galvanized sheet with screws. The screw spacing is controlled at 30 to 50 cm to ensure a close bond between the plywood and the galvanized sheet.

[0101] S6: Composite polyurethane foam insulation Material preparation and coating: Take polyurethane foam insulation material with a thickness of 20 to 50 mm, making sure that the foam sheet is free from defects and contamination.

[0102] Use a roller coating device to evenly apply the environmentally friendly adhesive to the surface of the galvanized sheet and plywood, with a coating amount of 200 to 300 grams per square meter to ensure uniform coverage.

[0103] Foam lamination and lamination: Carefully place the polyurethane foam sheet between the galvanized sheet and the plywood, making sure the sheets are aligned.

[0104] The panels are pressed using a mechanical pressing device with a pressure of 0.2 to 0.4 MPa. The pressing time is controlled within 2 to 3 hours to ensure the firmness of the adhesive layer and the uniform compaction of the foam material.

[0105] S7: Module assembly Installation of assembly block 1 and assembly block 2: Install assembly block 1 and assembly block 2 in sequence according to the designed positions, ensuring that their outer walls are correctly aligned and fixed.

[0106] Use bolts to fix the assembly block to the plywood and base frame below. The bolt specification is M10 and the tightening torque is controlled between 50 and 70 Nm.

[0107] Installation of assembly block three: Assembly block three is installed on the right side of assembly block two, ensuring a tight fit. The installation of assembly block three requires the use of dowel pins and bolts to ensure precise alignment and a stable connection of the structure.

[0108] Installation of assembled window block one: Install the assembly window block 1, which needs to be connected to the lower surface of the assembly block 2. The window block 1 is connected to the assembly block 2 by welding or bolting, ensuring that the connection point is not loose.

[0109] Installation of assembled door blocks: Install the assembly door block on the right side of assembly block three. During installation, ensure that the door opens and closes smoothly.

[0110] The door block is connected to the frame with hinges. The hinges need to be lubricated after installation to ensure smooth opening and closing.

[0111] Installation of assembly window block 2: Install the second assembled window block, which is located on the right side of the assembled door block and is tightly combined with the door block.

[0112] Use bolts and sealant to fix the window block to the door block, ensuring the joint is airtight to prevent rain and dust from entering.
