The service life cycle of a construction waste chute directly affects the procurement plan. Short-term projects (rental or standard type) and long-term projects (heavy-duty purchase) differ in cost, configuration, and maintenance strategies. Longkang provides differentiated solutions based on project duration.

- Short-Term Project Plan
Applicable: short-term works of ≤3 months
Recommended plan: purchase or rent a Standard HDPE chute
Configuration recommendations:
- Diameter: 400mm or 500mm Standard
- Wall thickness: 6–8 mm
- Sections: 1.5m standard section
- Buffer: one at the bottom is sufficient
- Accessories: basic configuration (feed inlet + discharge outlet + clamps)
Cost considerations:
- Purchase Standard: 80–120 yuan per meter
- Rental: 20–30 yuan per meter per month
- Rental is more cost-effective for short-term projects
- Longkang provides rental services
Advantages:
- Low upfront investment
- Fast installation
- Return or resell after use
- Suitable for a single project
Considerations:
- Wall thickness can be appropriately reduced for short-term projects
- Buffer sections cannot be omitted (safety requirement)
- Feed inlet movable door cannot be omitted (dust control requirement)
- Clean and maintain after use, then return to the rental provider
III. Medium-Term Project Plan
Applicable: medium-term works of 3–6 months
Recommended plan: Heavy-duty purchase
Configuration recommendations:
- Diameter: 500mm
- Wall thickness: 8mm
- Sections: 1.5m Heavy-duty section
- Buffer: one every 25m
- Accessories: full configuration
Cost considerations:
- Purchase Heavy-duty: 120–150 yuan per meter
- For a 6-month usage period, purchase is better than rental
- Can be reused for the next project after completion
Advantages:
- High cost-performance
- Good durability
- Can be transferred to other projects
- High residual value
Considerations:
- Medium-term projects have high usage frequency; wall thickness must be adequate
- Buffer sections installed per specifications
- Inspect connectors regularly
- Clean and maintain after project completion, store for future use
- Long-Term Project Plan
Applicable: long-term works of 6–12 months
Recommended plan: Reinforced purchase + customized configuration
Configuration recommendations:
- Diameter: 500–600 mm
- Wall thickness: 10mm Heavy-duty
- Sections: 1.5m Reinforced section
- Buffer: one every 15–20 m
- Accessories: full set + wear-resistant liner + inspection sections
Cost considerations:
- Purchase Reinforced: 150–200 yuan per meter
- Durable type is required for long-term use
- Reduces mid-project replacement costs
- High residual value after project completion
Advantages:
- Most durable, no replacement needed during service life
- High throughput, meets peak demand
- High safety and reliability
- Can be reused across multiple projects
Considerations:
- Buffer sections must be denser for long-term projects
- Comprehensive inspection every 3 months
- Wearing parts (sealing rings, fasteners) replaced regularly
- Wear-resistant liner at bottom discharge outlet
- Account for wear from two-shift operation
- Ultra-Long-Term Project Plan
Applicable: ultra-large works of >12 months
Recommended plan: customized solution + O&M service
Configuration recommendations:
- Diameter: 600mm Customized
- Wall thickness: 10–12 mm
- Buffer: multi-stage buffer every 10–15 m
- Smart monitoring: vibration sensors, blockage alarm
- Dust removal system: bottom negative-pressure dust extraction
Cost considerations:
- Customized solution: 200–300 yuan per meter
- Includes installation and O&M service
- Longkang provides regular inspections
- Optimal long-term total cost
Advantages:
- Safest and most reliable
- Intelligent management
- Professional O&M support
- Meets green construction requirements
