In urban subway construction, shield muck treatment has become one of the main options for tunnel construction. A large amount of waste from shield tunneling construction will cause harm to urban environmental pollution. Larger adverse effects. In the shield construction of urban subway tunnels, the current method for efficient separation and dehydration of shield muck includes vibrating screen water. The vibration effect has obvious effects on the drainage consolidation degree of the muck and increasing the drainage volume.
How to deal with shield muck
Feeding + dispersing + screening + screw + water wheel + dewatering screen + sand washing and recycling, etc.; in the mud treatment process, if it is directly transported out, it will not only cost a lot, but also be left on the road, resulting in dust and great pollution . At the same time, a large amount of reusable sand, gravel, soil, water, bentonite and foam contained in the slag should be treated as waste slag, which will cause a huge waste of resources.
GREEN's shield muck treatment system has been successfully put into use in the Kazakhstan Metro project recently. The muck that has just been excavated by the belt conveyor is transported from the tunnel to the ground muck separation system, and finally the fine sand and coarse sand are separated. Soil recycling has produced environmental benefits.
