Prefabricated House Foundation Solution

The prefabricated house foundation solution should be selected based on specific project requirements. Common solutions include prefabricated foundation beam-column construction, prefabricated house foundation construction, and moisture-proof treatment for rural self-built houses. The following is a detailed introduction:

Prefabricated Foundation Beam-Column Construction Solution (Taking a residential community project as an example)

Construction Preparation: Clearly define the organizational structure, with the project management department coordinating overall operations and the construction team responsible for specific tasks such as installation and welding. Select materials that comply with national standards, including prefabricated components, steel bars, and cement. Equip with production lines, transport vehicles, lifting equipment, and testing devices. Conduct technical briefings to familiarize construction personnel with the process flow and safety regulations. Construction Process: Divided into three stages:

1. Production Stage: Control the bending angle and welding quality during steel bar processing. After concrete pouring, use covering curing or steam curing to ensure the strength meets standards. Secure the components during transportation after demolding to prevent damage.
2. Installation Stage: Measure and set out to determine the position of the components. Clear debris and compact the foundation. Use a two-point lifting method for lifting to avoid deformation. Check the quality of welds during welding and reinforce with temporary supports or bolt connections.
3. Acceptance Stage: Inspect for defects such as cracks and honeycombs on the appearance. Ensure dimensional deviations comply with regulations. Verify strength through the rebound method or core drilling method. Quality Control: Focus on the precision of steel bar processing, concrete mix ratio, and curing period. Record data throughout the process and retain test blocks.

Prefabricated House Foundation Construction Solution

Pre-construction Preparation: Complete on-site surveys to determine parameters such as foundation bearing capacity and burial depth. Clear the site and prepare equipment such as excavators and level gauges. Construction Steps:

1. Ground Leveling: After excavating to the design elevation with an excavator, use a level gauge to calibrate the ground flatness.
2. Foundation Excavation: Dig vertically according to the design dimensions, with a horizontal bottom to avoid stress concentration.
3. Foundation Treatment: Remove loose soil at the bottom, compact in layers to the design density, and lay a waterproof membrane to prevent groundwater infiltration.
4. Foundation Pouring: Set up formwork, pour prefabricated concrete, and use a vibrator to compact and remove air bubbles.
5. Foundation Curing: Spray water for moisture retention and cover with plastic film. The curing period should be no less than 7 days to avoid early loads. Safety and Quality Control: Regularly check equipment stability, monitor concrete slump and strength development, and ensure the foundation bearing capacity meets design requirements.

Moisture-Proof Solution for Rural Self-Built House Foundations (Prefabricated Panel Suspended Floor)

Moisture-Proof Membrane Laying: After backfilling and compacting the foundation, lay 10-15 cm of fine sand and gravel for leveling, cover with a 0.2-0.5 mm thick moisture-proof membrane, turn up the edges by 30 cm, and finally pour a 10 cm thick concrete cushion. This method is cost-effective but requires avoiding sharp objects from puncturing it. Prefabricated Panel Suspended Floor: After pouring the ground beam, backfill soil to a height of 30-50 cm from the ground, compact it, and then lay prefabricated concrete panels (with a thickness of ≥8 cm). Fill the gaps between the panels with cement mortar. The moisture-proof principle is to form an air circulation layer through the suspended floor to block the upward path of moisture, which is suitable for humid areas. During construction, pay attention to the compaction degree of the backfill soil and the bearing capacity of the prefabricated panels to avoid cracking due to settlement.
