Container House Water and Electricity Layout Diagram

The water and electricity layout of container houses should be systematically designed in combination with specific functional areas (such as office areas, canteens, and living areas), covering the layout of power distribution, water supply, drainage, and communication networks to ensure safety and functionality.

I. Key Points of Power Distribution System Design

The power distribution system needs to cover the electricity demands of lighting, sockets, networks, and power equipment.

1. System Architecture: Adopt a hierarchical power distribution model. Branches are led from the main distribution box to each functional area (such as offices and canteens), and then connected to end-use equipment through sub-distribution boxes. For example, separate branches are set up for office lighting and sockets, and high-power electrical appliances in the canteen (such as induction cookers) have separate circuits to avoid overloading.
2. Circuit Layout: Strong-current circuits (lighting, sockets) and weak-current circuits (networks, telephones) should be laid separately to avoid signal interference. In the floor plan layout of office network and telephone sockets, cables are usually laid along the corners of walls or inside suspended ceilings and connected to dedicated information boxes.
3. Safety Measures: All circuits need to be protected by metal conduits or flame-retardant PVC conduits. Socket circuits should be equipped with leakage protectors, and lighting circuits should have overload protection devices.

II. Key Points of Water Supply System Design

The water supply system needs to solve the problems of water pressure balance and pipe anti-freezing in double-story living container houses.

1. Hierarchical Water Supply: The water source is introduced into the ground floor through the main water supply pipe and then transported to the second floor through a vertical riser. The riser can be arranged along corner columns or dedicated pipe shafts to reduce space occupation. Horizontal branch pipes on each floor are connected to water points (such as washbasins and shower rooms), and the branch pipes are hidden in the ceiling interlayer or floor joists.
2. Water Pressure Regulation: If there is a large difference in water pressure between the two floors, a pressure reducing valve should be installed in the middle of the riser (when the water pressure on the ground floor is too high) or a booster pump (when the water pressure on the second floor is insufficient) to ensure water comfort.
3. Anti-freezing Treatment: Pipes exposed outdoors or in non-heated areas need to be wrapped with insulation cotton to prevent freezing and cracking at low temperatures. For example, the main入户 (inlet) pipe of container houses in northern regions needs to be equipped with an electric tracing tape for auxiliary insulation.

III. Key Points of Drainage System Design

The drainage system mainly adopts same-floor drainage and needs to solve the problems of drainage slope and odor.

1. Same-floor Drainage Principle: The drainage branch pipes of sanitary fixtures on the ground floor are collected under the finished floor surface and then discharged to the outdoor septic tank or municipal sewer through a horizontal main horizontal pipe; the drainage branch pipes on the second floor are collected under the floor of this floor, and the main horizontal pipe and riser are hidden in the ceiling space of the ground floor to avoid penetrating the floor slab.
2. Pipe Material and Slope: PVC-U pipes are preferred for drainage pipes due to their corrosion resistance and ease of installation. The main horizontal pipe should maintain a slope of 1%-2% to ensure smooth drainage.
3. Odor Prevention Measures: A vent cap is installed at the top of each main drainage riser to balance the air pressure inside the pipe; a water trap is set under each drainage fixture to isolate odors using a water seal.

IV. Key Points of Communication Network Design

The communication network needs to meet the needs of office work and living, and the circuits should be independent of the strong-current system.

1. Wiring Specifications: Network and telephone cables should use Category 5e or Category 6 shielded twisted-pair cables, laid along dedicated cable trays or through conduits to avoid crossing with strong-current circuits.
2. Equipment Configuration: Each workstation in the office should be equipped with network and telephone sockets. The canteen can be equipped with additional wireless access points to cover the dining area; at least one network interface should be reserved in each room of the living container house.
