Application of Construction Waste Chutes in High-Rise Building Construction

Vertical transport of construction waste is a major challenge in high-rise building construction (above 7 floors). Traditional tower crane lifting is inefficient and costly, and manual transport is even less feasible. The Longkang HDPE construction waste chute is an ideal solution for high-rise building construction. This article introduces its application in high-rise building construction.

1. Pain Points of Waste Transport in High-Rise Buildings

Great height: 30–100 m, making manual transport impossible

Low efficiency: tower crane lifting occupies crane time

High cost: tower cranes are charged by the hour, making waste lifting uneconomical

Safety risks: risk of objects falling from height

Heavy dust: traditional methods cause severe fugitive dust

2. Pipeline Design

500 mm Standard or 600 mm Heavy-duty diameter

8–10 mm wall thickness

Buffer section every 15–25 m

Fixing point every 3–4 m

2. Installation Method

Mounted along the exterior wall

Fixed using external scaffolds or structural anchors

Feed inlet on each floor

Sealed collection hopper at the bottom

3. Operational Performance

5–10 times higher efficiency

Does not occupy the tower crane

Cost reduced by over 60%

Safe and reliable

Dust reduced by 80%

III. Application at Different Heights

1. Mid-rise (7–12 floors, 20–40 m)

500 mm Standard

Buffer section every 25 m

Fixing point spacing 4 m

Meets daily construction needs

2. High-rise (13–33 floors, 40–100 m)

500–600 mm Heavy-duty

Buffer section every 15–20 m

Fixing point spacing 3–4 m

Multi-stage buffering and deceleration

3. Super high-rise building (above 33 floors, >100 m)

600 mm Customized

Buffer section every 10–15 m

Segmented design

Dedicated dust removal system

1. Coordination with Standard Floor Construction

Main structure construction stage: the pipeline is extended floor by floor

Masonry stage: large waste volume, the chute operates at full capacity

Decoration stage: light waste, the chute achieves high efficiency

After external scaffolding removal: the pipeline is re-fixed with structural anchors

1. Safety Measures

Sealed feed inlet on each floor

Bottom protective canopy

Secure fixing points

Buffer section design

Daily inspection

1. Economic Analysis

Traditional tower crane lifting:

Tower crane cost: 200 yuan/hour

2 hours of lifting per day

Monthly cost: approximately 12,000 yuan

6-month construction period: 72,000 yuan

Longkang chute:

Purchase cost: approximately 15,000 yuan

Installation labor: approximately 3,000 yuan

Maintenance: approximately 1,000 yuan

Total cost: approximately 19,000 yuan

Savings compared with tower crane: 53,000 yuan
