Description
Technical field
Present invention relates to claw single-chamber tunnel bagger method of work.
Background technology
The bagger of large tunnel at present, generally use shield machine, but involve great expense, it is therefore desirable to design function and
Shield machine is similar, but the bagger of low cost.
The content of the invention
In view of this, in order to solve the above problems, the present invention provides claw single-chamber tunnel bagger method of work.
Claw single-chamber tunnel bagger method of work, it is characterized in that：Including tubular rotary portion, connected with tubular rotary portion
Grab digging portion, tubular rotary portion is internally provided with pipeline, grab digging portion be several circumferential arrays, cross section is oval, leans on
The cross section in the nearly tubular rotary portion finger-shaped calvus bigger than remote tubular rotary cross section, each finger-shaped calvus energy
Enough circumference radial direction both forward and reverse directions formed to finger-shaped calvus are bent so that finger-shaped calvus can internally or back-flexing shape
Into opening or closed configuration；The finger-shaped calvus inner hollow, upper surface, lower surface are provided with and internal cavities conducting
Through hole, finger-shaped calvus top is that open type is either closed or closed, and finger-shaped calvus top is sharp angle；Institute
State finger-shaped calvus internal cavities to tubular rotary portion to extend, and outside device for injecting liquid, aspirator connect simultaneously.
In use, 1）First sprayed water on soil, open tubulose rotating part, the rotation of digging portion, finger-shaped calvus tip are grabbed in drive
Twisting function is opened, constantly changes angle of bend to inside and outside, while the through hole turned on by upper surface, lower surface and internal cavities
Outwards water spray；
2）Soil digs pine, in the presence of the revolving force of digging portion 1 is grabbed, soil after being readily wetted by water, and by finger-shaped calvus tip
A periphery is cut open, now tubular rotary portion pushes ahead, upper surface, the intermittent water spray-absorption of the through hole of lower surface
Mud-water spray, such tunnel bagger advances to front, while cutting mud, while dredging, mud is drawn on side.
Further, finger-shaped calvus opens laterally can be compacted soil wall, prevent soil wall from collapsing.
Further, finger-shaped calvus is the flexible tubular thing formed that is nested together mutually by some section sleeves.
Further, finger-shaped calvus can bend 180 degree to the direction of the circle center away from finger-shaped calvus composition,
Similar octopus antenna.
Further, tubular rotary portion can be bent.
Further, the through-hole diameter of finger-shaped calvus lower surface can be adjusted.
Brief description of the drawings
Fig. 1 is finger-shaped calvus closure（Forward direction bending）When side view.
Fig. 2 is that finger-shaped calvus opens（Forward direction bending）When side view.
Fig. 3 is that finger-shaped calvus opens（Back-flexing）When side view.
Fig. 4 is finger-shaped calvus sectional view.
Fig. 5 finger-shaped calvus upper surface, upper surface through hole distribution schematic diagram.
Embodiment
With reference to figure 1-3, claw single-chamber tunnel bagger method of work, including tubular rotary portion 2, and tubular rotary portion 2 connect
What is connect grabs digging portion 1, and tubular rotary portion 2 is internally provided with pipeline, grab digging portion 1 be several circumferential arrays, cross section be oval
Shape, the cross section finger-shaped calvus bigger than remote tubular rotary cross section close to tubular rotary portion, each finger
Shape calvus can be bent to the circumference radial direction both forward and reverse directions that finger-shaped calvus forms so that finger-shaped calvus can be internally or anti-
To be bent to form opening or closed configuration；The finger-shaped calvus inner hollow, upper surface, lower surface are provided with and inside is empty
The through hole of chamber conducting, finger-shaped calvus top are that open type is either closed or closed, and finger-shaped calvus top is point
Sharp angle；The finger-shaped calvus internal cavities extend to tubular rotary portion, and outside device for injecting liquid, aspirator are same
When connect.
Such as Fig. 4-5, the finger-shaped calvus inner hollow is provided with cavity 11, and upper surface 111, lower surface 121 are provided with
The through hole turned on internal cavities 11, finger-shaped calvus open top, and finger-shaped calvus top is sharp angle；The finger
Shape calvus internal cavities extend to tubular rotary portion 2, and outside device for injecting liquid, aspirator connect simultaneously.
In use, first being sprayed water on soil, tubulose rotating part 2 is opened, drive is grabbed digging portion 1 and rotated, finger-shaped calvus tip
Open twisting function（Constantly change angle of bend to inside and outside）, while being led by upper surface 111, lower surface 121 and internal cavities 11
Logical through hole is outwards sprayed water.Soil digs pine after being readily wetted by water, and by finger-shaped calvus tip, is grabbing the revolving force of digging portion 1
Under effect, soil is cut open a periphery, and now tubular rotary portion 2 pushes ahead, upper surface 111, the through hole of lower surface 121
Intermittent water spray-absorbent slurry-water spray, such tunnel bagger advances to front, while cutting mud, while dredging, mud is drawn on side.
Finger-shaped calvus opens laterally can be compacted soil wall, prevent soil wall from collapsing.
