With the rapid economic development of the country, in order to alleviate the inconvenience and trouble caused by traffic, many cities across the country are building subway projects. How to deal with the shield muck of subway engineering? The importance of the shield muck treatment solution will directly lead to serious consequences of geological changes and urban pollution. Subway shield dregs have small particles and high moisture content. Improper treatment can easily cause environmental pollution and potential safety hazards. If the urban road damage and environmental impact caused by the export of the muck cannot be solved in time, it will also be caused the problem that the shield construction is blocked. 

The shield muck treatment system developed by KOSUN for the subway shield has recently been successfully put into use in a domestic subway project and has achieved initial results. The belt conveyor system is used to transport the newly excavated muck from the depth of the tunnel to the ground muck separation system. In the hopper, the final separated coarse sand and fine sand are transported to trucks through a pull-up belt conveyor. The residue is dewatered, separated and dried in stages, so as to realize the reuse of inorganic raw materials, water resources, and the recycling and reuse of the residue. The shield muck treatment solution effectively separates the stone, sand, and water in the shield muck, so the volume of the outgoing muck transportation project is greatly reduced, and a lot of construction costs are saved.

KOSUN shield muck treatment system has a good solid-liquid separation effect, saves a lot of water resources, and reduces the clean water problem of the soil transported out of the country. This has reduced the serious pollution of the city’s appearance caused by the shield dregs transportation.
