More specifically illustrate that working method of the present invention is as follows:
The present invention uses a kind of sliding formwork cast in situs engineering method, is exactly to be mixed scene mixed using slipform casting structure
Solidifying soil is transported in sliding formwork mold 6 by concrete conveying pipe 7, and sliding formwork mold 6 is for cooperating concrete curing molding, to rigid
After degree intensity reaches certain requirement, then by axial hydraulic motion structure 10, leg lock structure driving sliding formwork mold 6 along pipeline axis
To slow movement.It is exactly three be pre-placed in duct wall or more steel pipes that this, which moves relied on carrying object to be,
22.Meanwhile this three steel pipes 22 are also the counter-force supporter of shield going-forward.
When shield machine is walked, leg lock is fixed on one end of steel pipe 22 by hydraulic coupling, then recycles axial hydraulic movement
The thrust opposite with direction of travel to leg lock one of structure 10, is just able to achieve walking certainly for shield machine in this way.Due to leg lock structure
On for control leg lock clamping steel pipe 22 micro hydraulic cylinder 21 be with entirely move axially hydraulic motion structure hydraulic cylinder
Be connected, thus leg lock to the clamping force of steel pipe 22 can with the variation of shield machine axial traveling resistance real-time change, thus
Leg lock is avoided the case where whole process is all overlaid, effectively improves the service life of leg lock.When leg lock is covered
Entire stroke on axial hydraulic rack, hydraulic structure will pressure release, leg lock will unclamp under the action of reset spring 26
Steel pipe 22, subsequent leg lock shift to initial position under the action of axial hydraulic structure.
During this period, steel pipe splicing body 11 will be automatically performed the splicing of steel pipe 22, and later, leg lock clamps steel pipe 22,
Axial hydraulic structure plays a role again, and tunneling process just loops back and forth like this progress.Referring to Fig. 3, being equipped in Leg-clamping mechanism
Bolt for connecting leg lock rigid body 25 connects 23.
The axial hydraulic motion structure 10 is the movement mechanism of reciprocation cycle, in the axial hydraulic fortune with fixed function
Axial movement is oriented in dynamic structure 10, so that steel pipe 22 only will receive axial pressure, ensure that the stability of steel pipe 22；
Steel pipe 22 has been changed every time, and leg lock will be clipped in one end opposite with connector of steel pipe 22, leg lock dress under the action of hydraulic device
It also is provided with rubber thin-bed in setting, to realize biggish frictional force, is arranged to adaptive, leg lock simultaneously for such hydraulic structure
Clamping force as required axial action changes shield machine in real time during traveling, in this way to prevent from being expert at into process
In, there is leg lock insufficient clamping force and the phenomenon that skidding on steel pipe 22.
The replacement of steel pipe 22 and docking are the processes of an automation, can pass through the work of steel pipe splicing body 11
With realization, steel pipe splicing body 11 is similar to a hyperbolic roller mechanism, when needing replacing steel pipe 22, two songs in this structure
The distance of roller increases, so that steel pipe 22 is called in wherein automatically, possesses one layer of rubber thin-bed on roller, in the hope of increasing friction force, then,
With the rolling of curved roll, so that the forward movement that steel pipe 22 orients, is perfectly docked up to another steel pipe 22.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
Within the technology that is not directed to of the present invention can be realized by the prior art.
