Detailed installation process analysis of water, Electricity and
decoration inside Double-layer expandable Container Houses
In accordance with the design drawings of the water supply and
drainage system, lay the water supply and drainage pipelines inside
and outside the container module. For water supply pipes, either PP
- R pipes or galvanized steel pipes are generally used, while PVC -
U pipes are adopted for drainage pipes. During installation, adhere
to the principle of “horizontal straightness and vertical
alignment”. The spacing of pipe supports should comply with
relevant specifications (for PP - R pipes, the support spacing is
generally 0.6 - 1.0m; for PVC - U pipes, it is 1.0 - 1.5m).
For water supply pipes, connect the reserved interfaces of the
container module using either hot - melt welding or threaded
connections. For drainage pipes, use socket - type connections.
Ensure proper sealing at all joints to prevent water leakage.
Meanwhile, install auxiliary water supply and drainage facilities
such as water taps, sanitary ware, floor drains, and inspection
wells. Guarantee the smooth operation of the entire water supply
and drainage system without any leakage.
Based on the electrical design drawings, lay electrical pipelines,
including lighting circuits, power circuits, and weak - current
circuits (for networks, telephones, televisions, etc.). Electrical
pipelines can be installed either by threading them through pipes
(steel pipes or PVC pipes) or using trunking. The routing of
pipelines should avoid structural stress - bearing parts as well as
areas prone to high temperatures or moisture.
Select wires and cables that meet the design requirements for
current - carrying capacity and voltage. Connect wires using
terminal blocks or welding to ensure secure connections. Install
electrical equipment such as distribution boxes, switches, sockets,
and lamps. Distribution boxes are typically installed at a height
of around 1.5m. Switches and sockets are installed at heights that
comply with specifications (usually 1.3m for switches and 0.3m for
sockets). Lamps should be installed firmly and aesthetically,
ensuring the safe and reliable operation of the entire electrical
system.
Carry out interior wall and floor finishing according to usage
requirements. For walls, decorative materials such as latex paint,
wallpaper, or integrated wall panels can be used. If using latex
paint on container module walls, first perform base - layer
treatment (sand, level, and apply putty) on the walls, then apply
latex paint at least twice to ensure the walls are smooth and the
color is uniform.
For floors, options include floor tiles, wooden flooring, or epoxy
flooring. Before laying floor tiles, level the floor and use dry -
hard cement mortar for paving, ensuring uniform and straight gaps
between tiles. For wooden flooring, proper moisture - proof
treatment is necessary, and it can be installed either in a
floating or fixed manner. For epoxy flooring, follow the sequence
of applying a primer, a middle coat, and a top coat, ensuring the
floor surface is smooth, wear - resistant, and slip - resistant.
If a ceiling is required, options include light steel keel ceilings
or integrated ceilings. For light steel keel ceilings, first
install main and auxiliary keels, with spacing complying with
design requirements (main keels are generally spaced around 1.2m
apart, and auxiliary keels 0.4 - 0.6m apart). Then install ceiling
panels (such as gypsum boards or aluminum 扣板). Leave gaps between
panels and seal them with sealant.
Partitions can be made of lightweight partition boards (such as
gypsum partition boards or color - steel plate partitions) or glass
partitions. Lightweight partition boards are installed using tongue
- and - groove joints and reliably connected to the steel structure
frame of the container module. Glass partitions use stainless steel
or aluminum alloy frames, with glass and frames sealed with
sealant. Ensure partitions are installed firmly and provide good
sound insulation.
Conduct a comprehensive cleaning of the entire construction site
and the interior of the container mobile house. Remove construction
waste, debris, and dust generated during the construction process.
Clean doors, windows, walls, floors, and equipment to ensure the
mobile house is tidy and clean, meeting the conditions for delivery
and use.
Commission and inspect installed components such as doors, windows,
electrical and plumbing equipment, stairs, and railings. Ensure
doors and windows open and close flexibly, locks function properly;
electrical and plumbing equipment operate stably without water or
electricity leakage; and stairs and railings are firm without
looseness. Repair and improve minor defects (such as insufficiently
filled sealant or minor scratches on walls) to ensure project
quality.
Conduct acceptance checks on sub - projects such as foundation
construction, container module installation, enclosure component
installation, electrical and plumbing pipeline installation, and
interior finishing in accordance with the construction sequence.
Inspect whether the construction quality of each sub - project
meets design requirements and relevant construction specifications
and standards. Examples include checking the concrete strength and
dimensional deviations of the foundation; the installation accuracy
and connection firmness of container modules; the sealing and
insulation performance of exterior wall panels; and the laying
routes and connection quality of electrical and plumbing pipelines.
Promptly rectify any sub - projects that fail acceptance.
On the basis of passing sub - project acceptances, conduct an
overall project acceptance. An acceptance team consisting of
representatives from the construction unit, contractor, design
unit, and supervision unit will comprehensively inspect and accept
the overall appearance, structural safety, and completeness of
functional use of the double - layer expandable container mobile
house.
Check whether the overall layout of the mobile house meets planning
and design requirements, whether the structure is safe and reliable
(through settlement observation, structural deformation detection,
etc.), whether various functional uses (office, accommodation,
water and electricity supply, etc.) operate normally, and whether
relevant documents (construction drawings, hidden project
acceptance records, material inspection reports, sub - project
acceptance records, etc.) are complete. After passing the
acceptance, sign the project acceptance report for official
delivery and use.
Through the above - detailed installation and construction process,
the double - layer expandable container mobile house can be
constructed quickly, efficiently, and with high quality, meeting
usage requirements in different scenarios. Meanwhile, it features
good expandability and recyclability, providing a reliable
implementation approach for the application of temporary and
modular buildings.
