Specific embodiment
In conjunction with Fig. 1, conventional dual stage slurry shield machine all have it is independent matched into plasma discharge system, to the first slurry shield machine
For, first into plasma discharge system be from 1 first discharge pipe 2 of the first slurry shield machine be discharged mud controlled through the first electrically operated valve 3
System enter the first separation equipment 4 separated, after through the second electrically operated valve 5 control flow into the first sedimentation basin 6 precipitated, sink
Mud behind shallow lake is discharged into the first adjustment pond 7 and is matched again, and proportioned mud is again through the first inlet pipe road 8 input the
One slurry shield machine.For the second slurry shield machine, second into plasma discharge system be from 9 second discharge pipe of the second slurry shield machine
10 discharge mud through third electrically operated valve 11 control enter the second separation equipment 12 is separated, after through the 4th electrically operated valve
13 controls flow into the second sedimentation basin 14 and are precipitated, and the mud after precipitating is discharged into second adjustment pond 15 and is matched again,
Proportioned mud inputs the second slurry shield machine 9 through the second inlet pipe 16 again.
Described first into plasma discharge system the first electrically operated valve, the first separation equipment and the second electrically operated valve electrical interlocks
System control is lower independently to realize the electronic in third into plasma discharge system into plasma discharge cyclic process, described second of the first slurry shield machine
The electrical interlocks system control of valve, the second separation equipment and the 4th electrically operated valve is lower independent realize the second slurry shield machine into
Plasma discharge cyclic process.
The present invention is a kind of mutual switching method of dual stage slurry shield machine into plasma discharge system, the mutual switching method of the present invention
Solve the problems, such as be: if the first slurry shield machine is passed through by the second slurry shield machine of high risk source lag or the in advance
Two slurry shield machines are passed through in advance by the first slurry shield machine of high risk source lag or the first slurry shield machine has passed through
High risk source and the second slurry shield machine is passing through or the second slurry shield machine passes through high risk source the first muddy water shield
Structure machine is passing through, when two slurry shield machine doubling constructing tunnels are in the weight over long distances such as fast rail, high speed, village, high voltage transmission line tower
When big high risk source, it is necessary to be that a slurry shield machine is lagged or surpassed by another of high risk source slurry shield machine in advance
Before pass through, this is an important safe construction precondition, it is necessary to be acted in accordance with it, the consequence otherwise generated is very serious
's.At this time if wherein a slurry shield machine is when above-mentioned separation equipment failure occurs in high risk source, how to pass through dual stage mud
Water shield machine realizes under high risk source mutual switching problem into plasma discharge system to reach the purpose of normal construction.
Related particular content of the invention does not repeat separately referring to the technical solution.
Although the present invention increases the connection of the 5th electrically operated valve 17 and the 6th electrically operated valve 18 in the technical solution
Mode, but the resulting third can then realize the first muddy water shield into plasma discharge system into plasma discharge system and the described 4th respectively
Into the mutual switching of plasma discharge system between structure machine and the second slurry shield machine, and realize the dual stage slurry shield machine under high risk source
Mutually switch into plasma discharge system, the meaning and creativeness that this mutual switching method generates to those skilled in the art and saying is
Self-evident, generated beneficial effect is also obvious.
Need it is clear that:
1, in view of the mud index of localized tunnel construction needs is different, so if wherein a slurry shield machine exists
It is electronic by the 5th although matched separation equipment breaks down when above-mentioned separation equipment failure occurs in high risk source
The unlatching of valve 17 and the 6th electrically operated valve 18 and another separation equipment is returned to former sedimentation basin and carries out again in original adjustment pond
Proportion, shield machine need different simulated muds in different construction parts, so mud index use or original, this
It is a little extremely important, to guarantee that two slurry shield machine mud are not used in mixed way.
2, when slurry shield machine is in shutdown status, although the separation equipment of the slurry shield machine is used to pass through
The mud that 5th electrically operated valve comes be will not reflux into the slurry shield machine, this is because the slurry shield machine shut down shape
There is closing function when state itself, therefore mud reflux phenomenon will not be generated.
As seen through the above analysis: the present invention realizes the mating separation equipment intercommunication of two shield machines and mutually uses, and uses
The control of electronic plate valve saves artificial, time cost, the achievable separation equipment switching when shield machine passes through the great dangerous source of wind
The case where ensure that the smooth driving of shield machine, and then preventing ground grout and collapse improves slurry shield machine construction
Security reliability.
