Method.
Background technique
In conjunction with Fig. 1, the feeding system of existing routine shield machine is: mortar passes through mortar tank car 1, feeding hose 2, first-hand
Dynamic feeding plate valve 3 and feeding hard tube 4 finally enter in high-order slurry can 5, and it is conveying mortar that wherein mortar tank car 1, which is equipped with mortar pump,
Power resources, feeding hose 2 be high-intensity flexible pipe facilitate mortar tank car 1 to dock with feeding hard tube 4, first manual feeding plate valve
3 are connected between feeding hose 2 and feeding hard tube 4, and slurry can 5 is the interim slurry-storing container of shield machine.
It needs to close first manual feeding plate valve when mortar tank car is withdrawn, at this moment will be stored in feeding hard tube a small amount of
Mortar simultaneously causes feeding hard tube to block because of mortar solidification.
When equipment fault, process entanglement, mortar traffic interruptions occurs in shield machine, this is because being in a high position, also have
Part mortar, which flows back into feeding hard tube, leads to its blocking.
If solidification mortar cannot be cleared up in time in feeding hard tube, the normal driving of shield machine is influenced, increases shield machine construction
Risk.
Summary of the invention
To solve the above problems, passing through the present invention provides a kind of improved method for preventing shield machine feeding hard tube from blocking
This method is able to solve feeding hard tube not blockage problem, guarantees shield machine normal construction, improves constructing tunnel efficiency, and shield is applied in reduction
Structure machine construction risk.
For achieving the above object, the present invention adopts the following technical scheme:
A kind of improved method for preventing shield machine feeding hard tube from blocking, base of the improved method in former shield machine feeding system
It includes sand that the second manual upper flitch valve, air inlet pipe, manual air inlet ball valve and breather check valve, the feeding system are increased on plinth
Tank car, feeding hose, first manual feeding plate valve, feeding hard tube and slurry can are starched, it is characterized in that:
Mortar tank car is coupled by feeding hose with first manual plate valve, and first manual plate valve passes through feeding hard tube and second
The connection of manual feeding plate valve, the second manual upper flitch valve pass through feeding hard tube again and couple with slurry can, in first manual plate valve and
Air inlet pipe is concatenated on feeding hard tube between second manual upper flitch valve and is connected in manual air inlet ball valve one end, manual air inlet ball
The valve other end is coupled by air inlet pipe with breather check valve；
Need to close first manual feeding plate valve when mortar tank car is withdrawn, at this time the pressure-air of 8~12Bar by into
Gas check valve, manual air inlet ball valve and the second manual upper flitch valve generate thrust to the mortar in feeding hard tube and make mortar stream
Enter in slurry can, until mortar jar vehicle re-enters mortar and closes manual air inlet ball valve；
When equipment fault, process entanglement, mortar traffic interruptions occurs in shield machine, first manual feeding plate valve is closed in time
And thrust is generated simultaneously to the mortar in feeding hard tube by breather check valve, manual air inlet ball valve and the second manual upper flitch valve
Flow into mortar in slurry can, up to the above-mentioned troubleshooting of shield machine and mortar jar vehicle re-enters mortar and turns off manual air inlet
Ball valve.
Due to using technical solution as described above, the present invention generates following good effect:
1, the mortar that the present invention can be realized in shield machine feeding hard tube is cleared up in time, prevents feeding hard tube from blocking,
Reduce blocking bring clearance time, reduces construction waste, improve production efficiency.
2, the present invention passes through the increase of the second manual upper flitch valve, manual air inlet ball valve and breather check valve, meets shield
Machine tunnels demand, and effectively preventing feeding hard tube influences the construction of shield machine because of blocking, improves the safety of shield machine construction
Reliability.
Detailed description of the invention
Fig. 1 is the structure schematic diagram of conventional shield machine feeding system.
Fig. 2 is the structure schematic diagram of feeding system of the present invention.
In above-mentioned figure: 1- mortar tank car, 2- feeding hose, 3- first manual feeding plate valve, 4- feeding hard tube, 5- storage slurry
Tank, the manual upper flitch valve of 6- second, 7- air inlet pipe, the manual air inlet ball valve of 8-, 9- breather check valve.
Specific embodiment
The present invention is a kind of improved method for preventing shield machine feeding hard tube from blocking, and improved method of the invention can be effective
Solve the problems of background technique.
The present invention is that the second manual upper flitch valve 6, air inlet pipe 7, hand are increased on the basis of former shield machine feeding system
Dynamic air inlet ball valve 8 and breather check valve 9, former feeding system include mortar tank car 1, feeding hose 2, first manual feeding plate valve 3,
Feeding hard tube 4 and slurry can 5.
The connecting relation that the above-mentioned component that former feeding system and the present invention increase newly is constituted is referring to the technical solution, not separately
It repeats.
The method that the present invention solves the blocking of feeding hard tube is as follows:
1. needing to close first manual feeding plate valve when mortar tank car is withdrawn, the pressure-air of 8~12Bar passes through at this time
Breather check valve, manual air inlet ball valve and the second manual upper flitch valve generate thrust to the mortar in feeding hard tube and make mortar
It flows into slurry can, until mortar jar vehicle re-enters mortar and closes manual air inlet ball valve.
2. closing first manual upper flitch in time when equipment fault, process entanglement, mortar traffic interruptions occurs in shield machine
Valve simultaneously generates thrust to the mortar in feeding hard tube by breather check valve, manual air inlet ball valve and the second manual upper flitch valve
And flow into mortar in slurry can, until the above-mentioned troubleshooting of shield machine and mortar jar vehicle re-enter mortar turn off manually into
Balloon valve.In conjunction with Fig. 2, the present invention is increased to be increased manual feeding plate valve 6 newly and is located at after manual feeding plate valve 3, and is close to
On the pipeline for expecting the feeding hard tube 4 of 2 side of hose.Increased air inlet pipe 7 is located at manual feeding plate valve 3 and increases manual upper flitch newly
Between valve 6.Increased manual air inlet ball valve 8 is located on the pipeline of air inlet pipe 7 with breather check valve 9.
Although the second manual upper flitch valve, air inlet pipe, manual air inlet ball valve and breather check valve are conventional parts,
It is then that this field has no in the new feeding system for solving the problems, such as that feeding hard tube is blocked and constituted, passes through manual air inlet
The one-way high-pressure air inlet of ball valve is fully able to solve feeding hard tube blockage problem, secondly first manual feeding plate valve, and second manually
The chain control of feeding hard tube conveying mortar, acquired using effect and warp may be implemented in feeding plate valve and manual air inlet ball valve
Effect of helping is obvious.
