Description
Technical field
The present invention relates to a kind of devices applied and prevent cutterhead mud cake from being formed on slurry shield machine, can also wash away not
The mud cake of forming.
Background technology
Shield machine is a kind of rock tunnel(ling) machine using shield method.The construction method of shield is development machine structure while driving
It builds（It is laid with）Tunnel its " shield "（Refer to supportive section of jurisdiction）, it is different from open type construction method.In the world, broad sense shield machine also may be used
For lithostratigraphy, it is only different from open type（Non- shield method）Rock tunnel(ling) machine.And in China, it will traditionally be used for soft
The rock tunnel(ling) machine of soil layer is known as（Narrow sense）Shield machine, by being known as lithostratigraphy（Narrow sense）TBM.
Shield machine comes out has nearly 180 years history so far, starts from Britain, is developed in Japan, Germany.In the past 30 years,
By to key technology earth pressure balanced, in slurry type shield machine, such as effective sealing of shield machine, it is ensured that excavation face it is steady
Determine, control surface uplift and be collapsed upon within prescribed limit, cutting-tool's used life and the cutter changing under air-proof condition,
It the exploration for the treatment of technology to for example high hydraulic condition of some severe geology etc. and researchs and solves, shield machine is made to have quickly
Development.Shield machine is especially earth pressure balanced and slurry type shield machine in Japan due to economic fast development and Practical Project
It needs have developed rapidly.The shield machine technology of Germany also has one's own knack, especially during underground construction, before ensureing sealing
It carries and replaces the cutter on cutterhead up in the case of 0.3MPa air pressures, to improve an Excavation Length of shield machine.Moral
State also developed under air-proof condition, and the cutter being worn is replaced out of large-diameter cutter head inside normal pressure space.
In the tunneling process of clay stratum, the cohesive soil of excavation surface is rolled shield machine by cutterhead, it is easy to from knife
Disk center position gradually forms the mud cake of attachment on cutterhead face and native storehouse inner wall around, so as to cause the stock-removing efficiency of cutterhead
It reduces, extends the driving time, increase the torque of cutterhead and the thrust of shield, also increase the failure-frequency of equipment.Existing muddy water
Multi-stage water pump pressurization tap water is partly used on balanced shield machine, cutterhead is then sent by centre of gyration pipeline, in cutterhead
High pressure water is injected between opening to be lubricated cutterhead face, reduces the frictional force that cutterhead faces the front soil body, while utilizing injection water
Pressure shoots down a small amount of clay adhered at cutter head panel central opening.But in actual construction, the aperture of cutterhead water injection hole is smaller,
It is blocked by the stone in the soil body easily in tunneling process, to which forfeiture acts on.In addition, the water of cutterhead water filling is smaller, lubrication
Effect and percussion are limited, in the continuous very strong rock stratum of viscosity, often can not effectively prevent the formation of mud cake, be applied to shield
Work causes prodigious difficulty.
Invention content
The present invention to solve the above-mentioned problems, provides a kind of shield machine combination knife group.
The technical scheme is that：
