Description

Technical Field

[0003] Due to the limitation of urban ground space, the construction method that occupies a large enclosure area is no longer applicable; and mud is used in many underground space constructions. The existing mud treatment equipment occupies a large area and has a slow filtration speed. At the same time, it requires a larger and longer construction area to be enclosed, which greatly affects the normal traffic in the city; at the same time, the mud treatment equipment will directly discharge the treated sewage, resulting in a waste of resources. In the prior art, such as a device for separating mud by mechanical method with publication number CN218653402U, the device can achieve efficient separation of slurry, but the separated mud slurry cannot be directly recycled, which will cause a waste of resources.

The discharged mud water needs to be re-proportioned before it can be injected into the grouting system.
