Earth pressure balance shield mud solidification treatment system

Abstract

The invention discloses an earth pressure balance shield mud solidification treatment system. The earth pressure balance shield mud solidification treatment system comprises an intelligent chemical adding control system, an intelligent double-shaft stirring system and an intelligent master control system, wherein the intelligent chemical adding control system is internally provided with a comprehensive chemical, the discharging end of a shield mud storage pool is connected with one feeding end of the intelligent double-shaft stirring system, a chemical throwing opening of the intelligent chemical adding control system is connected with the other feeding end of the intelligent double-shaft stirring system, the residue discharging end of the intelligent double-shaft stirring system is connected with a mud unloading pool through conveying equipment. According to the earth pressure balance shield mud solidification treatment system, intelligent chemical adding control is achieved, chemicaladding is smooth, stirring is uniform, the solidification effect is good, the energy consumption is low, therefore randomness and inaccuracy of manual chemical adding are eradicated, the cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of sludge, mud, slag treatment and environmental protection, in particular to an earth pressure balance shield mud solidification treatment system. Background technique [0002] Most of the urban subway tunnels are constructed by the shield method, and the output of shield dregs is also increasing with the continuous increase of the subway construction mileage. In the domestic earth pressure shield construction, usually after the muck enters the muck pit, it is usually transported away directly without any treatment, and no specific muck treatment equipment is required. However, with the further standardization and strengthening of environmental protection measures, corresponding management measures have been specially formulated for the disposal of shield tunneling construction slag. The flow-plastic muck after the improvement of the earth pressure shield contains a large amount of fluid mud, which is difficult to p...
