Operation.
Figure 14 is referred to, it is overall to tunnel step and foregoing when development machine 010 works on stratum such as sand, cobble, hard rocks
In clay tunnel step it is essentially identical, difference is, now insert soil layer realize increase resistance provide holding power mode
To stretch out increasing resistance component 100a friction member 40, the frictional force between the external friction plate 41 and soil layer of friction member 40, which is provided, increases resistance
With the holding power of advance.
In summary, the development machine 010 in the embodiment of the present invention can drive stretching for cutting member 50 and friction member 40 respectively
Go out and retract, the effect that soil layer provides holding power is held on in stratum that can be in difference, with wide, the workability using scope
The stable beneficial effect of energy.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
