Container House Water and Electricity Design
The water and electricity design of container houses should integrate their modular and movable characteristics, achieving a safe, efficient, and easy-to-maintain water and electricity system through reasonable planning of pipeline layouts, selection of appropriate materials and equipment, and optimization of construction techniques.
Pipeline Layout Design
The water and electricity pipeline layout in container houses should fully consider space utilization and ease of later maintenance. The wiring for water and electricity should preferably be concealed, embedding the pipelines into the walls or floor layers to avoid occupying space and affecting aesthetics when exposed. For example, PVC pipes or metal wire ducts can be pre-embedded in the side walls or floors of the container for threading wires and water pipes, with maintenance ports reserved for subsequent repairs. The pipeline routing should follow the principle of the shortest path, reducing the number of bends and joints to lower the risk of water leakage or electric shock. For example, the water supply pipe can be introduced from one end of the container and laid straight along the corner or beneath the floor to each water point; the electrical circuit should adopt branch control, with independent wiring for lighting, sockets, and high-power appliances to avoid overloading.
Material and Equipment Selection
The suitability of materials and equipment directly affects the stability and lifespan of the water and electricity system in container houses. It is recommended to use PPR pipes or stainless steel pipes for water pipes, with the former being corrosion-resistant and easy to install, and the latter having high strength and a long lifespan, both suitable for the outdoor environments that containers may face. Wires should be flame-retardant copper wires, with wire diameters matched according to the electrical load, such as 1.5 square millimeters for lighting circuits, 2.5 square millimeters for socket circuits, and over 4 square millimeters for high-power appliances like air conditioners. Water and electricity equipment such as distribution boxes, water meters, and valves should be compact products to fit the limited space of containers. For example, a distribution box composed of miniature circuit breakers can be integrated into the corner of the container; angle-type water meters or concealed valves can be selected to reduce occupied space.
Construction Technique Optimization
The water and electricity construction in container houses should balance efficiency and quality. 3D modeling technology should be used to plan pipeline layouts in advance, avoiding collisions and rework during construction through virtual simulation to ensure one-time success. For example, the positions of sockets, switches, faucets, and other terminal points can be precisely located according to the furniture layout inside the container to avoid wall damage from later modifications. Welding techniques should ensure a firm connection between the steel structure frame and pipelines, especially when water pipes pass through the container walls, where rubber sleeves or metal sleeves should be installed at the openings to prevent friction damage. Electrical circuit installation should strictly follow grounding specifications, with an equipotential bonding terminal box set up on the steel structure of the container to reliably ground all metal components and prevent electric shock accidents.
Adaptation to Special Scenarios
Given that container houses may be used in outdoor, temporary, or mobile scenarios, the water and electricity design should incorporate adaptive features. For example, a rainwater collection system can be integrated in areas with abundant rainfall, directing rainwater from the roof into storage tanks through gutter channels for later use in flushing toilets or irrigation after filtration; water pipes should be insulated in cold areas, wrapped with rubber foam or electric tracing tapes to prevent freezing and cracking; quick-connect joints should be used in mobile scenarios to facilitate rapid disassembly and assembly of water and electricity pipelines during container relocation, reducing downtime.
