Abstract Of The Continuous Muck Removal Belt Conveyor System For Subway Tunnels
Application Field
Muck transportation system (muck removal system) for subway tunnel construction.
System Highlights
Reinforced structure, stable operation, large lifting height.
Equipment Selection
DSJ Telescopic Belt Conveyor, Large Angle Vertical Sidewall Belt Conveyor, Pipe Belt Conveyor
System Service
Juxin provides design and equipment manufacturing of muck removal and earth discharge belt conveyor systems for subway tunnel construction.
Applicable Materials
Muck materials generated during tunnel excavation.
Introduction Of The Construction Waste Discharge Project
Metro tunnels are constructed underground, which generates a large amount of excavated soil.
In urban metro construction, earth excavation primarily employs two methods:
Tunnel Boring Machines (TBMs) used for hard rock tunnels.
Shield machines used for soft soil or mixed-ground tunnels.
The excavated soil or rock debris is transported via built-in conveyor systems (in TBMs/shield machines) to belt conveyors, which then carry it to the surface for disposal.
Key Equipments Of The Metro Tunnel Muck Disposal System
Muck Discharge Belt Conveyor System for Metro Tunnel Boring Process Primarily uses DSJ Telescopic Belt Conveyor!
Installed inside the tunnel and aligned with the advancing direction of the tunnel boring machine/shield machine.
The conveyor belt automatically extends as the shield machine advances underground.
Muck Vertical Lifting System for Metro Tunnel Construction Mainly employs Large Angle Vertical Sidewall Belt Conveyor!
Capable of lifting soil vertically or at steep angles to the surface.
Ideal for use in compact spaces and features high-efficiency transportation.
Tunnel Muck Discharge Belt Conveyor System Installed in the Tunnel – Telescopic Belt Conveyor Belt Winding Device!
Automates soil stacking and temporary storage.
Ground Belt Winding Device for the Muck Discharge Telescopic Belt Conveyor and Large Angle Vertical Sidewall Belt Conveyor for Vertical Muck Lifting in Metro Tunnels!

Continuous Muck Removal System for Tunnels |
Gantry Crane + Muck Box |
|
It has strong muck removal capacity, meeting demands exceeding 1,500 t/h, 6.8 times the efficiency of gantry cranes and 2.7 times that of corrugated belt conveyors, with highly efficient transportation. |
It requires multiple sets of transportation equipment, leading to limited loading and transport capacity. As tunnel length increases, transfer cycles lengthen and efficiency decreases. |
|
It features a high level of automation, enabling remote centralized control to reduce workers' labor intensity. |
Currently, this method is widely used but relies on manual on-site operations. |
|
It is easy to maintain, operates reliably, and occupies minimal space for auxiliary facilities. |
Its dispatching and management are complex, requiring significant effort for track laying and maintenance, along with large space occupation for auxiliary facilities. |
|
It offers a simplified layout with separated muck removal and material transport lines, effectively avoiding construction interference. |
It suffers from prolonged operational cycles, leading to significant construction interference issues. |
|
It reduces the load on track transportation and improves construction efficiency. |
It poses safety hazards due to the use of large gantry cranes and muck trucks. |
|
It enables continuous muck removal, providing energy-saving, high-efficiency, and environmentally friendly operation. |
It is not suitable for tunnels with steep slopes. |
|
It demonstrates strong adaptability to accommodate various on-site process layouts. |
