Container House Water and Electricity Layout

The water and electricity layout of container houses should be designed in combination with spatial planning, functional requirements, and construction specifications, typically using pre-embedded pipelines, modular installation, and reasonable zoning to achieve efficient and safe water and electricity supply.

1. Pre-embedding of Water and Electricity Pipelines and Modular Installation

The water and electricity pipelines of container houses are usually pre-embedded during the factory production stage. For example, after the welding of the steel structure frame is completed, pipeline channels are reserved during the prefabrication of wall panels and roof panels. Internal water and electricity pipelines (such as PVC drainage pipes, PPR water supply pipes, and wire conduits) are directly embedded in the wall or floor sandwich layers. This pre-embedding method can avoid on-site slotting that may damage the structure and improve construction efficiency. For container houses that require multiple disassemblies and assemblies, pipeline interfaces adopt standardized modular designs (such as quick-connect water pipe joints and distribution boxes), facilitating rapid disassembly and reassembly during relocation.

2. Functional Zoning and Planning of Water and Electricity Points

The water and electricity layout should determine the positions of points based on the functional zoning of the house. For example:

• Living Scenarios: Bedrooms need to reserve sockets and lighting switches; bathrooms need to arrange water supply pipes, drainage pipes, and equipotential grounding terminals; kitchens need to design upper and lower water pipes, range hood exhaust pipes, and multiple sets of sockets.
• Office Scenarios: Conference rooms need network interfaces and projector power supplies; office areas need dense sockets and independent electricity meter boxes.
• Special Scenarios: For example, container shower rooms can integrate rainwater collection systems, introducing rainwater into storage tanks through roof diversion pipes and using the filtered water for toilet flushing or irrigation.

3. Construction Specifications and Safety Measures

Water and electricity construction should comply with national specifications (such as GB 50016 'Code for Fire Protection Design of Buildings'), with key points including:

• Waterproofing: Moist areas such as bathrooms and kitchens need to be coated with waterproof paint, and pipeline penetrations through walls should be sealed.
• Electrical Safety: Adopt the TN-S grounding system, install leakage protectors in distribution boxes, and lay wires in different colors (red for live wires, blue for neutral wires, and yellow-green for ground wires).
• Ventilation Design: Mechanical ventilation openings should be set up in areas with dense water and electricity equipment (such as distribution rooms) to avoid short circuits caused by moisture.

4. 3D Modeling to Optimize Construction

Some projects use 3D modeling technology to simulate the routing of water and electricity pipelines, avoiding pipeline conflicts in advance. For example, in a double-wing expandable container project, the relationship between water and electricity points and the positions of foldable furniture is determined through a BIM model to ensure that the pipelines are not compressed after expansion.
