With the rapid economic development of our 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 dregs of subway engineering? The importance of the shield dregs treatment plan will directly lead to serious consequences of geological changes and urban pollution.

 

Subway shield dregs have small particles and high moisture content. Improper handling can easily cause environmental pollution and potential safety hazards. If the urban road damage and environmental impact caused by the export of the dregs cannot be solved in time, it will also be caused by the inability of the dregs to be shipped out in time. The problem that the shield construction is blocked.

 

The 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 to separate and dry the sludge, so as to realize the reuse of inorganic raw materials and water resources, as well as the recycling and reuse of the sludge. The shield muck treatment plan effectively separates the stone, sand, and water in the shield muck, so it greatly reduces the volume of the outgoing muck transportation project and saves a lot of construction costs.

 

The shield muck treatment plan used by KOSUN has a good solid-liquid separation effect, makes good use of the circulating water for shield construction, saves a lot of water resources, and reduces the clean water problem of the soil transported abroad, and also solves the problem. This has reduced the serious pollution of the city’s appearance caused by the shield dregs transportation.
