Flat-Pack Container Emergency Hospital Construction Project

II. Main Challenges

Extreme timeline pressure:

Required construction of 500-bed quarantine hospitals within 96 hours during pandemic outbreaks

Specialized medical functional requirements:

Implementation of “Three Zones and Two Passages” (clean zone/semi-contaminated zone/contaminated zone; medical staff passage/patient passage)

Stable maintenance of negative pressure room air pressure difference ≥5Pa

High system integration complexity:

Integration of medical gas pipelines, intelligent management systems, and sewage treatment devices

Adaptability to extreme environments:

Normal operation required in temperatures ranging from -30℃ (northeastern China) to 40℃ (southern China)

III. Solutions

Modular combination design:

Medical units: 6m×3m standard modules configured for:

Negative pressure ward units (4 beds/unit)

Medical staff office units (including buffer rooms/changing rooms)

CT container units (3-module combination)

Passage system: Double-layer corridor containers (lower level for patients/upper level for medical staff)

Rapid deployment technology:

95% factory prefabrication: Including wall panel openings and pre-embedded pipelines

On-site assembly: 6-person team can assemble 1 ward unit per hour

Integrated hoisting: Supports up to 3-story container stacking

Medical-specific integration:

Wall-embedded medical service columns (oxygen/negative suction/power interfaces)

Roof-integrated negative pressure exhaust systems (HEPA filtration efficiency 99.97%)

Full-floor waterproofing membrane (medical-grade silicone sealing at joints)

Intelligent management system:

IoT monitoring system: Real-time tracking of ward temperature/humidity/air pressure

One-click disinfection: Remote timed activation of UV lamps

Patient call system: Bedside terminals directly connected to nursing stations

IV. Product Details

Main structure:

Frame: Q355B high-strength steel (seismic resistance Grade 8)

Wall panels: 100mm rock wool sandwich panels (Class A fire rating, sound insulation Rw=42dB)

Medical-specific configurations:

Doors/windows: Airtight medical doors + double-layer antibacterial glass windows

Flooring: 2mm PVC medical sheeting (antibacterial and corrosion-resistant)

Interfaces: Pre-embedded medical gas pipelines/weak current systems/water supply and drainage pipes

Environmental control systems:

Negative pressure system: 300m³/h air volume (per ward)

HVAC system: Medical-grade split AC + fresh air exchange

Disinfection system: Hydrogen peroxide spray disinfection devices

V. Project Achievements

Construction speed:

Wuhan Leishenshan Hospital: 1,000-bed hospital built in 10 days

Hong Kong Emergency Hospital: 500 isolation wards hoisted in 5 days

Medical effectiveness:

Negative pressure stability: Air pressure fluctuation < ±1Pa

Air cleanliness: Meets WHO standards for medical spaces

Sustainability:

Reuse rate: 90% materials can be disassembled and reused

Adaptability: Rapid conversion to vaccination centers/fever clinics

Industry Value Demonstration
Flat-pack container houses have achieved through highly industrialized production and innovative modular design:

Setting benchmarks for “China construction speed” (3-day hospital construction)

Solving the “dual-use for peace and pandemic” challenge (seamless conversion between temporary and permanent functions)

Establishing new standards for “smart medical infrastructure” (integration of 5G/IoT systems)

Practicing “green development” principles (＞90% material recycling, 80% construction waste reduction)

This model has been implemented in 28 provinces across China, accumulating over 5 million square meters of emergency medical facilities, serving as a exemplary Chinese solution for global pandemic response.
