QMH 12KM continuous turning steel cord conveyor belt, equipped with water conservancy engineering TBM excavation spoil long-distance conveying, has been operating stably for nearly six months in this project since it was put into operation at the beginning of 2024.

Conveying distance: 12KM   Buffer storage: 580m

Continuous turning: 4    Turns with a radius of 500m

Conveying capacity: 250 TPH    Belt speed: 3.15m/s

Daily operation time: more than 20 hours  Daily excavation volume: 1000m+

Project Challenges

The overall conveying distance of the project is long, with multiple continuous turns, complex layout and long continuous working hours.

The project adopts the first 4.03m diameter gantry open-type TBM in China, with high excavation efficiency. Considering the site conditions and geological conditions, the conveyor belt itself and the equipment configuration have put forward higher requirements:

① High requirements for flexibility of the steel cord conveyor belt.

② High requirements for the wear resistance of the belt edge

③ Need to meet the long-term stable operation in a highly wear-resistance environment, and at the same time meet the transportation requirements of high efficiency and energy saving.

 Solutions

Facing the complex site conditions and customer pain points, QMH delivered a steel cord conveyor belt system with higher wear resistance, longer service life, smoother operation, and overall performance better matched to complex terrains for the project. It solved the problems of frequent belt longitudinal cracking and local crushing in long-distance multi-turn conveying, effectively met the on-site construction excavation and conveying volume needs, and effectively improved the comprehensive operation efficiency and conveying system safety of the project.
