Anti-blocking muddy water type shield tunneling machine stirring device

Abstract

The invention discloses an anti-blocking muddy water type shield tunneling machine stirring device. The anti-blocking muddy water type shield tunneling machine stirring device comprises a cutter headand a first stirring paddle. A shell is arranged at the rear of the cutter head, and an earth bin is arranged at the inner side of the shell. A sealing ring is arranged at the rear of the earth bin, and a pressure-bearing partition plate is arranged at the rear of the sealing ring. A feeding pipe is arranged above the pressure-bearing partition plate, and a threaded rod is arranged on the inner side of a discharging pipe. The first stirring paddle is located in front of the pressure-bearing partition plate, and a second stirring paddle is arranged at the rear of the first stirring paddle. A third stirring paddle is arranged at the rear of the second stirring paddle. A self-aligning roller bearing is arranged at the rear of a transmission rod, and a reducer is arranged at the rear of a coupling. According to the anti-blocking muddy water type shield tunneling machine stirring device, the second stirring paddle can be matched with the third stirring paddle during the use of the device, the mud crushed by the first stirring paddle can be stirred for many times, so that the soil can be stirred more finely and not prone to congealed.

Description

technical field [0001] The invention relates to the technical field related to tunnel excavation, in particular to an anti-clogging slurry type shield machine stirring device. Background technique [0002] Now tunnel boring machine construction is the main method of construction in my country's urban subway tunnels, road tunnels across rivers, and water or gas pipelines across rivers. The quality of the muck improvement in the shield machine's soil bin directly affects whether the shield machine is in In normal operation, the soil bin is not only a place to put the muck, but also stirs the soil to ensure the improvement of the soil. If the soil stirring device cannot make the soil have good flow plasticity and impermeability or cannot mix the muck with the The soil additives are fully stirred, which will cause the accumulation of soil in the center of the soil chamber wall of the large-scale earth pressure balance shield machine, and mud cakes will easily appear. After the mud...
