Container House Water and Electricity Configuration Requirements
The water and electricity configuration of container houses must meet safety, practicality, and compliance requirements, covering core aspects such as pipeline embedding, interface standardization, waterproofing, and compliance inspections. Details are as follows:
1. Embedding and Protection of Water and Electricity Pipelines
Water and electricity pipelines should be embedded during the factory prefabrication stage to avoid on-site wet operations. Electrical pipelines should be protected with conduits, and wire specifications should meet electrical load requirements (e.g., 1.5mm² for lighting, 2.5mm² for sockets), with sufficient external interfaces reserved. Water pipelines should distinguish between hot and cold water pipes, use corrosion-resistant materials like PPR, and be equipped with an independent drainage system to ensure proper slope and prevent water accumulation. For example, quick-assembly packing containers have built-in independent drainage systems and elevated sloped roofs to prevent leakage during heavy rain.
2. Standardized and Expandable Interfaces
Container houses should be equipped with standardized water and electricity interfaces to support quick connection to external water and power supplies. The electrical system should include a main switch, branch switches, and leakage protection devices to ensure electrical safety; the water system should have reserved inlets, outlets, and inspection ports for easy maintenance. For long-term living scenarios (e.g., rural residences, homestays), dedicated circuits for high-power appliances like air conditioners and water heaters should be added, along with independent electricity meters.
3. Waterproofing and Sealing
Sealing reinforcement should be applied at penetration points for water and electricity pipelines on roofs and walls, using waterproof glue or metal sleeves to prevent rainwater infiltration. For example, high-quality container roofs adopt multi-layer waterproofing structures, with all panel seams and screw points sealed, and their performance verified through water spray tests. Wet areas like bathrooms and kitchens should have additional waterproof layers, with a floor slope of no less than 2% to ensure smooth drainage.
4. Compliance and Inspection Standards
Water and electricity configurations must comply with national and local regulations, such as the Code for Acceptance of Construction Quality of Electrical Installation in Buildings (GB50303-2015) and the Code for Acceptance of Construction Quality of Water Supply and Drainage and Heating Works in Buildings (GB50242-2002). After construction, electrical continuity tests, water pressure tests, and leakage checks should be conducted to ensure no safety hazards. For example, a prefabricated mobile house project in Wuhan ensured product compliance with national standards through strict control of raw material procurement and production processes.
5. Adaptation to Special Scenarios
For extreme climates or special needs, water and electricity configurations should be optimized accordingly. For example, insulation layers should be added in high-altitude areas to prevent pipe freezing; cultural tourism projects can be equipped with solar power systems and rainwater harvesting devices for resource recycling.
