Problems solved by technology

In the gravel soil layer, the treatment efficiency of the above scheme is low, resulting in high energy consumption of the whole system
However, in formations with many fine particles such as clay and silt, the screening efficiency is greatly reduced, and the dewatering screen has a large amount of screen penetration, resulting in low separation efficiency of the entire mud separation station, increased waste slurry volume, and the waste slurry treatment capacity cannot match the shield machine. The speed of advancement will cause downtime, which will affect the progress of the project

Abstract

The invention provides a slurry shield slurry treatment system for a complex geographical environment. The slurry shield slurry treatment system comprises a slurry-water separation system, a slurry preparation and mixing system and a waste slurry treatment system, the mud-water separation system is connected with the slurry preparation and mixing system, and the slurry preparation and mixing system is connected with the waste slurry treatment system; the mud-water separation system is used for separating water and slag in the mud and discharging muck; the slurry preparing and mixing system is used for preparing new slurry and recycling the new slurry and the recycled and separated slurry; and the waste slurry treatment system is used for further separating water in the waste slurry, returning clear water to the slurry preparing and mixing system and discharging sludge. Different working modes can be switched in a targeted manner according to different geological conditions in a complex geographical environment, so that the processing efficiency of the system is improved, the energy consumption of the system is reduced, and resources are fully utilized.

Description

technical field [0001] The invention relates to the field of shield mud treatment, in particular to a muddy water shield mud treatment system under complex geographical environment. Background technique [0002] In shield tunneling engineering, a large amount of sludge will be generated during construction, which needs to be separated and treated. Chinese patent document CN207002551U describes a mud treatment system for shield tunneling engineering construction, and CN112250274A records a solid-liquid treatment of shield tunneling waste slurry. The separated mud treatment system and method thereof adopt the treatment route of pre-screening, first-level cyclone separation, second-level cyclone separation, and dewatering screen. In the sand and pebble formation, the treatment efficiency of this scheme is higher. However, in tunnel shield engineering, complex geographical environments are often encountered, such as the composite strata on the underground driving section, which...
