Crushed rock, muck, and debris generated during highway tunnel excavation.
Introduction OF Highway Construction
As a crucial infrastructure investment, highway construction significantly drives regional economic development. Given China's vast territory and complex terrains in regions like Shaanxi, Sichuan, Guizhou, Yunnan, and Guangxi where mountainous landscapes dominate, bypass solutions prove economically inefficient, making tunnel construction through mountains the predominant approach.
Key Equipments Of Muck Removal Belt Conveyor System
Continuous Telescopic Belt Conveyor
It connects to the TBM's bridge conveyor, transporting muck from the tunneling face to the tunnel exit.
It automatically extends as tunneling progresses, maintaining alignment with the TBM's advance.
Transfer Belt Conveyor
Transport muck from the telescopic conveyor to the stacking yard or directly load it onto trucks.
Stacking Machine
Internationally, rotary stackers are widely used to distribute muck in storage yards or load trucks.
Technical Advantages Of Continuous Muck Removal Belt Conveyor System
Seamless integration with TBMs for real-time muck removal.
01
Continuous operation with a capacity exceeding 1,500 t/h-6.8× higher than gantry cranes and 2.7× higher than corrugated belt systems.
02
Adjustable output synchronized with tunneling speed.
03
Long-distance transport without intermediate transfers.
04
Adaptability to steep slopes (up to ±25°).
05
High automation with remote centralized control, reducing labor intensity.
06
Flexible layout to avoid interference with material transport lines.
07
Significant social benefits, including reduced environmental impact and improved safety.
08
Advantages Of Continuous Muck Removal Belt Conveyor System

|
It has a strong slag discharge capacity and can meet the discharge demand of over 1500t/h. Its efficiency is 6.8 times that of a gantry crane and 2.7 times that of a corrugated belt conveyor, with a high conveying efficiency. |
There are many sets of transportation equipment, and the loading and transportation capacity is limited. The longer the tunnel, the longer the transfer cycle and the lower the efficiency. |
|
It has a high degree of automation and can achieve remote centralized control, reducing the labor intensity of workers. |
It is currently more commonly used and requires on-site manual operation. |
|
It is easy to maintain, reliable in operation and occupies a small area for auxiliary facilities. |
The dispatching and management are complex, the workload of track laying and maintenance is large, and the auxiliary facilities and the occupied space required are also extensive. |
|
The layout is simple and the slag discharge line is separated from the material transportation line, which can effectively avoid construction interference. |
The operation cycle is long and the problem of construction interference is prominent. |
|
Reduce the load of rail transportation and improve the construction efficiency. |
The use of large gantry cranes and dump trucks poses safety hazards. |
|
Continuous slag discharge, energy-saving, highly efficient and environmentally friendly. |
Not suitable for tunnels with a large slope. |
|
The line has strong adaptability and can meet various on-site process arrangements. |
