TBM Residue Treatment

In urban subway construction, TBM has become one of the main choices for tunnel construction. The large amount of waste residue generated in the shield tunneling construction has brought many challenges to the urban environment. The dewatering, transportation, and landfill of residue will have a large adverse impact on the environment. As a kind of urban mineral resources, residue will consume a lot of land resources in landfilling. If the residue is recycled to be used as synchronous injecting paste material, raw material of ecological brick, roadbed filling, etc., it will effectively improve the ecological and environmental protection function of subway construction. However, at present, the recycling rate of TBM residue in China is very limited, and a further research on residue applica
