Problems solved by technology

However, in actual construction, the hole diameter of the water injection hole of the cutter head is small, and it is very easy to be blocked by stones in the soil during the excavation process, thus losing its function.
In addition, the amount of water injected in

Abstract

The invention relates to a combination cutter set of a shield tunneling machine. The combination cutter set is characterized in that the combination tool set comprises an anti-mud device main body, afirst scouring pipe, a second scouring pipe, a third scouring pipe, a fourth scouring pipe, a fifth scouring pipe, a sixth scouring pipe, a seventh scouring pipe, an eighth scouring pipe and anti-muddevice mounting holes; the anti-mud device main body is a circular-ring pipe with the radius being smaller than the radius of a shield cutterhead; the first scouring pipe, the second scouring pipe, the third scouring pipe and the fourth scouring pipe are arranged on one side of the anti-mud device main body; the fifth scouring pipe, the sixth scouring pipe, the seventh scouring pipe and the eighthscouring pipe are arranged on the other side of the anti-mud device main body; and the multiple anti-mud device mounting holes are formed in the anti-mud device main body, the anti-mud device main body is arranged on the shield tunneling machine cutterhead, and a first shield tunneling machine hob set and a second shield tunneling machine hob set are arranged on the shield tunneling machine cutterhead.

Description

technical field [0001] The invention relates to a device applied on a muddy water shield machine to prevent the formation of mud cake on a cutter head, which can also wash away unformed mud cake. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of the shield is that the "shield" (referring to the supporting segment) of the tunnel is constructed (laid) by the roadheader while excavating, which is different from the open construction method. Internationally, the generalized shield machine can also be used in rock formations, but it is different from the open (non-shield method) tunnel boring machine. In our country, it is customary to call the tunnel boring machine used for soft soil formation (narrow sense) shield machine, and the one used for rock formation is called (narrow sense) TBM. [0003] The shield machine has a history of nearly 180 years since it came out. It started in Britain and deve...
