At present, a large amount of slag produced by shield construction has become a new problem that urgently needs to be solved to prevent environmental pollution. The treatment equipment and process for shield construction slag cannot be directly stacked and need to be effectively treated. Shield slag is treated in a direct outward transportation mode, which has problems such as pollution of the surrounding environment and high transportation costs, and there is an urgent need for an efficient, environmentally friendly, and economical treatment method. In addition, in order to improve the resource utilization rate of shield slag, the various components of the slag also need to be screened, and then each component is separately treated as a resource.

In addition to the steel concrete method used for the construction of the equipment foundation, there is no other steel concrete engineering. After the completion of a slag engineering, the system can be moved to another engineering for continuous use. The system has fewer demolition engineering and is more environmentally friendly. The sand and stone in the slag are separated and cleaned out to be used as building materials for self-use or sale. The system not only realizes the reuse of resources but also indirectly or directly creates economic benefits. The entire process is automatically controlled by a control system to be continuously completed. The system does not need equipment for secondary transportation, saves labor, machinery, and oil costs, greatly reduces the system operation cost, and mechanically dehydrates and dries the remaining soil after the separation of the engineering slag sand and stone.
