Abstract
The present invention relates to one kind for periphery tearing cutter, tearing cutter is provided in cutter head of shield machine arragement construction, including cutterhead, cutterhead under plastic draining board geological conditions, is additionally provided with cutter on the cutterhead；It when shield encounters plastic draining board barrier in tunneling process under complex geological condition, is cut by cutter, and barrier is delivered to bucket vehicle by screw machine.The present invention can make cutter head of shield machine solve the problems, such as that cutter head of shield machine is stuck under plastic draining board geological conditions by carrying out new arrangement to cutter head of shield machine, so that shield tunnel driving is more widely applied under complex geological condition.
Description
Technical field
The present invention relates to a kind of cutter head of shield machine, especially a kind of for cutter head of shield machine under plastic draining board geological conditions
Arragement construction.
Background technique
With a wide range of expansion of nation-building engineering, shield-tunneling construction becomes the mainstream construction party of subway, outlet tunnel etc.
Method, and construction operation conditions of environmental geology is multifarious, is influenced in tunnel excavating process by geological conditions, shield machine often occurs
Encounter that barrier cutterhead is stuck to cause Shield tunnel driving to be obstructed phenomenon in tunneling process, therefore, it is necessary to cutter head of shield machine
New arrangement is carried out to solve complex geological condition cutterhead stuck phenomenon.
Summary of the invention
The present invention is to provide for one kind for cutter head of shield machine arragement construction under plastic draining board geological conditions, for solving
The technical issues of stuck driving of cutter head of shield machine is obstructed under plastic draining board geological conditions.
To achieve the above object, the technical scheme is that it is a kind of for shield machine under plastic draining board geological conditions
It is provided with periphery tearing cutter, tearing cutter in cutterhead arragement construction, including cutterhead, cutterhead, is additionally provided with cutter on the cutterhead；When
Shield encounters plastic draining board barrier under complex geological condition in tunneling process when, cut by cutter, and by
Barrier is delivered to bucket vehicle by screw machine.
Further, the cutter are than the 1.5-2cm that dashes forward before tearing cutter.
Further, the cutter are made of hard tungsten alloy material, totally 12, are distributed between the king spoke of cutterhead
Six short spokes on, in 60 ° of distributions, arrangement 2 is cutter on every short spoke.
The beneficial effects of the present invention are: shield driving passes through improved cutterhead pair when meeting plastic draining board barrier
Plastic draining board, which cut, is crushed to smaller shape can smoothly enter into Tu Cang, by helical conveyer to bucket vehicle, to keep away
Exempt to cause cutter head of shield machine is stuck to tunnel the problem being obstructed because of plastic draining board.
Detailed description of the invention
Fig. 1 is cutter head of shield machine arragement construction schematic diagram of the invention；
Fig. 2 is cutter structural schematic diagram
Wherein: (a) main view, (b) right view, (c) top view.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, a kind of for cutter head of shield machine arragement construction under plastic draining board geological conditions, including cutterhead 1, knife
There is periphery tearing cutter 2, tearing cutter 3 on disk 1, and cutter 4 are set；When shield is met in tunneling process under complex geological condition
When to plastic draining board barrier, cut by cutter 4, and barrier is delivered to bucket vehicle by screw machine.
Cutter 4 are made of hard tungsten alloy material, and totally 12, six short spokes being distributed between the king spoke of cutterhead
On item 5, in 60 ° of distributions, two cutter 4 are arranged on every short spoke 5.The structure of cutter 4 such as Fig. 2 (a), (b), (c) institute
Show.
Cutter head of shield machine of the invention is equipped with special cutter, and speciality cutter are to pass through plastic draining board for this engineering
Region and specially design cutting plastics cutter, the impact of stone can be resisted, in design than before tearing cutter dash forward 1.5-2cm,
When cutterhead encounters plastic draining board, first thus sharp cutter cuts plastic draining board, cut it is broken after, be re-fed into screw machine
Conveying.It is equipped with high-strength tearing cutter simultaneously, reinforces breaking capacity of the knife disc tool to the plastic draining board for being blocked in outside.
Application implementation example of the present invention
Engineering is located at offshore sea waters, and tunnel is the artesian water drainage pipe of 2 internal diameter 6100mm, wall thickness 350mm, using combined type
Balancing earth-pressure shielding machine, tunnel are always about 1798m, buried depth about 18m.Shield tunnels the main composite earth layer passed through along the line are as follows: 2. 3
Layer Muddy Bottoms clay layer, 2. 4 layers of clay are locally mingled with 2. 31 layers of flour sand containing gravel, 2. 41 silty sand ground, and 2. 5 layers of powder is locally passed through in lower part
Matter clay, 3. 1 layer of clay.Plastic draining board with a large amount of quincuncial arrangements within the scope of shield export & import 100m simultaneously.Pass through
Using the present invention, make shield machine when meeting plastic draining board geological conditions, it is carried out by improved cutterhead to be effectively crushed simultaneously
It is conveyed by screw machine, avoids shield machine stuck phenomenon, saved a large amount of maintenance times, human and material resources and financial resources, be engineering
Bring good benefit.
