Description
Technical field
The utility model belongs to mountain tunnel construction technology, is specifically related to a kind of reducing TBM cutterhead.
Background technology
Due to the needs of China's modernization development, tunnel construction has been widely used in the numerous areas such as traffic, water conservancy, communication, metallurgy.A lot of tunnel has the features such as long, large, buried, complex geologic conditions, and the advantages such as hard rock mole (i.e. TBM) is wide with its excavation formation hardness scope, operating environment good, the level of informatization is high, high construction efficiency, is widely used in during tunnel builds.
TBM constructs on great burying weak surrounding rock stratum, under the effect of cutterhead excavation disturbance, change has been suffered in stratum virgin stress distribution, and Surrounding Rock Strength is low, poor stability, compared with under the effect of high confining pressure, the footpath, hole of excavation can reduce, and produces the geological disasters such as country rock convergence, distortion, large deformation, rock burst.For different buried depths, Surrounding Rock Strength and characteristic, tunnel convergence, distortion degree also different.
When shield formula hard rock mole passes through poor country rock, when especially passing through the fault belt of Deep-buried Long And Big tunnel, surrouding rock deformation is large, easy landslide, and the radial displacement of working as country rock is greater than the preset clearance between shield shell and outline excavation face, causes shield shell to be stuck, is referred to as card shield.Card shield causes programming and has a strong impact on, and some construction periods are downtime that card shield causes owing to accounting for 53% of total time in 1 to April.The impact that card shield is constructed on hard rock mole is very big, and at present, the major measure of reply card shield problem is the technology of getting rid of poverty after card shield, such as: side drift method, service gallery method and other artificial factures etc.And these techniques and methods are all less than solving card shield problem from root, be the counter-measure taked after card shield problem occurs.
When country rock convergence or distortion, by stuck for the parts such as the cutterhead of TBM, shield, can cannot get rid of poverty, can only stablize the country rock at cutterhead and shield top by auxiliary service market near TBM self, adopt the mode of hand excavation's cleaning, auxiliary cutterhead and shield are got rid of poverty.When country rock large deformation or rock burst, not only can block main frame and also can damage rear supporting on equipment, the even life of entail dangers to personnel.
