Abstract

The invention provides a shield tunneling machine with a muck drying function and a muck drying method of the shield tunneling machine. The shield tunneling machine comprises a plurality of dryers arranged in a shield tunneling cutter head. Each dryer comprises a shell of a cylindrical structure, and a stirring dehydration tank and a sealing area which are independent of each other are arranged in the shell. A rotating shaft is arranged in the stirring and dewatering tank, stirring blades of a spiral structure are arranged on the rotating shaft, and a plurality of circles of drying lamp tubes are annularly arranged on the inner wall of the stirring and dewatering tank; a slag inlet and a slag outlet which are communicated with the interior of the shell are respectively formed in two ends of the shell; according to the scheme, the dryer achieves drying operation in a shield machine room, the synchronous treatment capacity and efficiency of shield waste muck are improved, solid-liquid separation of gravel, soil and water in the shield muck can be achieved, the dryer is used for recycling in tunneling operation, and therefore the shield waste muck can be recycled. The resource value of the shield waste muck is greatly improved, and the total risk and cost in the shield waste muck treatment process are reduced.

Description

technical field [0001] The invention relates to the technical field of shield tunneling equipment, in particular to a shield tunneling machine with a dregs drying function and a dregs drying method thereof. Background technique [0002] The shield tunneling method has the advantages of strong ground adaptability, high construction efficiency, low cost, and relative safety, and is widely used in urban subway construction. Subway shield work needs to add modifiers such as water, bentonite mud, polymers and foaming agents to the dregs in front of the shield, so shield construction will produce a large amount of flow-plastic dregs. In 2020, the length of subway operating lines in my country (excluding Hong Kong, Macao and Taiwan) will reach 6,280.8 kilometers, an increase of 1,100 kilometers over the previous year, or a year-on-year increase of 21.24%. If the section diameter of subway tunnel excavation is calculated according to the common 7m, about 38,000 cubic meters of slag...
