At present, most of the dregs excavated by shield tunneling are the dregs and mud produced when the mud-water balanced shield tunneling machine is used to excavate, and a large amount of mud cake and mud will be produced when the mud-water balanced shield tunneling machine is excavated, which will pollute the surrounding environment and affect the ecological environment.
Sludge treatment
Xi ‘an KOSUN muck mud treatment system has recently been successfully put into use in a domestic subway project and achieved initial results. The belt conveyor system is used to transport the newly excavated muck from the depth of the tunnel to the feed hopper of the ground muck separation system. The coarse sand and fine sand that are finally separated are transported to the truck by the puller belt conveyor, and the muck is classified, dehydrated, separated, and dried. Realizing the reuse of inorganic raw materials and water resources has achieved the recycling of waste soil, and has also produced good economic benefits, adding a new “magic weapon” for green construction and urban infrastructure.
