Key Points for Custom Construction Waste Chute Selection

For special engineering conditions, a standard construction waste chute may not fully meet requirements. Longkang supports non-standard customization, designing dedicated chute solutions based on specific project conditions. This article explains the key points of customized selection.

1. When Customization Is Needed

Customization is recommended in the following cases:

1. Super high-rise buildings over 100m
2. Special installation locations (narrow alleys, indoor, special structures)
3. Special waste types (containing large metal blocks, high-temperature waste, corrosive waste)
4. Special specification requirements (non-standard diameter, non-standard section length)
5. Special functional requirements (dust removal, noise reduction, monitoring)
6. Customization Scope
7. Specification customization

• Diameter: any specification between 400–800 mm
• Wall thickness: 6–15 mm
• Section length: 1.0

–2.5m

• Shape: round / square / oval

2. Functional customization

• Buffer type: spiral buffer / enlarged buffer / multi-stage buffer
• Feed type: side feed / top feed / platform feed
• Discharge type: direct-drop / elbow / sealed / dust extraction interface
• Inspection type: observation opening / opening section / quick-release section

3. Material customization

• Standard HDPE
• Thickened HDPE (high wear resistance)
• Flame-retardant HDPE (with flame retardant)
• Anti-static HDPE (prevents dust static electricity)
• Food-grade HDPE (special projects)

4. Color customization

• Standard orange (safety color)
• Yellow, black, gray
• Can be printed with logo and warning signs

III. Customization Process

Step 1: Requirements communication

• Architectural drawings and construction plan
• Installation location conditions
• Waste type and waste volume
• Usage period
• Special requirements

Step 2: Site survey (large projects)

• Longkang technical engineers conduct on-site survey
• Measure installation location and structural conditions
• Confirm fixing point locations
• Photograph for records

Step 3: Solution design

• Selection calculation (diameter, sections, buffer)
• Installation plan (fixing method, routing)
• Safety design (protection, warning)
• Configuration list and quotation
• Solution delivered in 3 working days

Step 4: Drawing confirmation

• Provide installation layout drawings
• Structural load calculation report
• Production after customer confirmation

Step 5: Manufacturing

• Custom production according to drawings
• Customers can station at the factory to supervise key processes
• Pre-delivery inspection

Step 6: Delivery and installation

• Ship to site
• Installation guidance or professional team installation
• Acceptance and usage training

1. Custom Design Key Points
2. Structural load calculation

• Wind load calculation (high-rise wind vibration)
• Seismic load
• Pipe self-weight + waste weight
• Fixing point load
• Foundation bearing capacity

2. Buffer design

• Calculation of waste falling speed
• Energy dissipated by each buffer stage
• Bottom speed controlled to ≤15m/s
• Maximum impact without pipe rupture

3. Throughput calculation

• Waste density and volume
• Hourly throughput
• Pipe diameter matching
• Peak redundancy

4. Safety design

• Anti-blockage design
• Anti-splash design
• Anti-fall design
• Warning signs

1. Custom Case References

Case 1: Super high-rise residential building (120m)

• Diameter: 600mm Heavy-duty
• Buffer: one 45° buffer section every 12m, 9 stages total
• Fixing: chemical anchors into shear walls, one every 3m
• Accessories: sealed feed inlet per floor, bottom negative-pressure dust extraction
• Duration: 45 days production + 15 days installation

Case 2: Narrow alley demolition works

• Diameter: 500mm
• Installation location: narrow alley between two buildings (1.5m wide)
• Customization: short sections (1.0m) for installation in narrow spaces
• Elbow: elbow sections every 10m to reduce lateral force
• Fixing: triangular brackets anchored into buildings on both sides

Case 3: Metro tunnel project

• Waste type: muck + concrete chunks
• Diameter: 600mm Wear-resistant
• Inner wall lined with wear-resistant rubber
• Combined horizontal + vertical conveyance
• Dedicated horizontal section

1. Customization Considerations
2. Lead time: customization takes 15–45 days, plan in advance
3. Accurate drawings: building dimensions and structural conditions must be accurate
4. Installation conditions: whether the site has hoisting space
5. Acceptance criteria: clarify delivery standards and acceptance methods
6. After-sales support: warranty and repair for customized products
