Description
Technical field
This utility model relates to a kind of hard rock push-bench, especially a kind of hard rock push-bench deviation-rectifying system.
Background technology
Along with the increase of population and deepening continuously of urbanization process, urban pipe network builds the development risen in this world.
The composite ducts such as waterpipe, blow-off line, gas piping, heat distribution pipeline, power cable, communication cable are erected on the ground originally
Or the exposed situation on ground the most increasingly affects the attractive in appearance of city and builds, traditional method is typically all direct-burried ground
Under, this method is intricate, and needs again to excavate road surface when again laying or repair pipeline, not only causes economic wave
Expense has an effect on traffic.Many pipelines cannot meet urban development needs, and along with the development of the urbanization of China, city is managed
Net is built and has gradually been risen to new height, and composite duct is the most expanded and universal, and therefore construction by pipeline jacking method is with it
The advantages such as speed of application is fast, cavitation quality is high, safe and environment-friendly have obtained quick development.
In pipeline tunneling process, according to practical situation need adjust driving route with meet pipeline application or in order to
Hiding the reasons such as building needs push-bench to possess centering capacity.From the point of view of popular, it is simply that to turn in underground.Further, by
In the difference of each regional geology situation, pipeline applications is different with requirement, needs according to different geology bars in jacking construction
Part and pipeline applications design the push-bench matched therewith.Particularly when the stratum more containing rock or lithosphere are excavated
Need to use special cutter (hobboing cutter) to carry out brokenly rock, to guarantee the smooth driving of push-bench, generally this class push-bench is claimed
For rock ripper or hard rock push-bench.This kind of push-bench is when relatively hard formation tunnels, owing to cutterhead face cannot all be covered with rolling
Cutter, or because excavation face not all be made up of rock it is possible that hobboing cutter is stuck in rock stratum, and cutter head panel cannot continue
Advance, cause cutterhead turn motionless or cutterhead can rotate but cannot the situation of jacking forward.And due to limited space in equipment,
Artificially carry out brokenly rock the most difficult, and there is the biggest danger, easily cause security incident.Therefore, in design push-bench process
In not only require consideration for how to realize curve operation, in addition it is also necessary to by a kind of deviation-rectifying system of design with reach equipment can rely on from
Body function solves swaging clamp situation, it is ensured that equipment normally tunnels.
Utility model content
Deficiency that this utility model exists for prior art and defect, it is provided that one can solve the problem that and carries out cable, city
During the construction such as political affairs, the common piping lane in underground tunnel inner belt machine and the marshalling problem being difficult to slag tap that causes of insufficient space novel go out
The TBM of slag mode and slag tapping method thereof.
For achieving the above object, this utility model be the technical scheme is that a kind of hard rock push-bench deviation-rectifying system, bag
Including at least 3 group correction oil cylinders, anterior shield assembly and tail shield assembly are connected by correction oil cylinder, and tail shield shield body head is sleeved on front end shield
In body afterbody, and two shield body junctions are provided with hinge seal device, and described correction oil cylinder uses two-way cylinder, and its one end is hinged on
Being fixed on the bearing on anterior shield shield body inwall, the other end is hinged on the bearing being fixed on backing shield body inwall；Described hinge
Connect the two seals groove that sealing device includes radially being opened on tail shield shield body outer wall, be equipped with annular in described seal groove close
Seal, the thickness of described O-ring seal is more than the degree of depth of seal groove.
Further, described correction oil cylinder is distributed on anterior shield and backing inwall circumference.
Further, described sealing ring outer wall is provided with projection upwards.
Further, described convex cross section shape is triangular in shape, rectangle or trapezoidal.
The beneficial effects of the utility model are: this utility model deviation-rectifying system can efficiently solve push-bench and tunnel
Journey realizes the difficulty of curve operation, it is ensured that build the smooth excavation of straight line and non-rectilinear pipeline at underground pipe network, thus improve
Economic benefit, decreases difficulty of construction；Further, it is possible to solve the problem of push-bench card cutterhead in ground consisting of hard rock well,
Avoid the uncertain danger of artificial broken rock, it is ensured that the safety of jacking construction operator, it is ensured that push-bench is at subterranean tunnel
The safety of construction, reliability.
