Abstract

The invention discloses a slurry shield machine with a slurry circulation system. The slurry shield machine with the slurry circulation system comprises an excavation bin, a cutter, an air cushion bin, a gate, a slurry feeding assembly, a slurry discharging assembly, a pressurizer and a stone breaking device, wherein the gate is arranged between the excavation bin and the air cushion bin; the slurry feeding assembly comprises a first slurry feeding tube and a second slurry feeding tube; a slurry outlet of the first slurry feeding tube communicates with the excavation bin; a slurry outlet of the second slurry feeding tube communicates with the air cushion bin; the slurry discharging assembly comprises a first slurry discharging tube and a second slurry discharging tube; a slurry inlet of the first slurry discharging tube communicates with the excavation bin; a slurry inlet of the second slurry discharging tube communicates with the air cushion bin; the pressurizer comprises a ventilation opening which communicates with the air cushion bin; and the stone breaking device is arranged on an upstream side of the slurry inlet of the second slurry discharging tube. According to the slurry shield machine with the slurry circulation system, a first working mode and a second working mode of the slurry shield machine can be switched over when the slurry shield machine runs, and adaptation and tunneling ability of the slurry shielding machine are improved.

Description

technical field [0001] The invention relates to the field of tunnel engineering construction equipment, in particular to a mud-water shield machine with a mud circulation system. Background technique [0002] The mud circulation system is the core system of the mud-water balance shield machine. The main function of the circulation system is to take away the muck cut by the cutter head of the shield machine, and rely on the circulation system to control the pressure of the mud in the excavation chamber to balance the tunnel face. Water pressure and earth pressure maintain the stability of the tunnel face, so as to ensure the normal excavation of the shield machine. The performance of the mud circulation system directly determines the performance of the mud-water balance shield machine. The performance of the slurry circulation system of the mud-water balance shield machine is mainly reflected in the slag-carrying ability and precise pressure control function. [0003] The c...
