Specific implementation mode
The present embodiment is specifically described by taking the scheme for the shield separate launching that India New Delhi CC23 marks use as an example.
When India New Delhi CC23 marks are using shield construction, because launching shaft is located at bustling location, by surrounding enviroment
Condition limits, and removes and traffic leads to not implement, available initial zone length only has 45m, and shield host is matched after adding
The total length of complete equipment about 75m, starting well cannot be satisfied shield and integrally originate needs.To ensure that the duration finishes on schedule, using point
The mode that body originates is constructed, and the perforation in section is smoothly completed, and Specific construction scheme is as follows：
First shield body to 1# trolleys is gone into the well assembling in separate launching, transfer fuel tank is mounted on 1# trolleys, each in shield body
A executive component oil return sends ground hydraulic station back to by transfer fuel tank.
Referring to Fig. 1, transfer fuel tank described in the present embodiment has babinet 1, and controller 2, oil return pipe are equipped on babinet 1
Road 3, oil outlet pipe 4 and respirator 5 and the liquid-level switch 6 of three upper, middle and lower arrangement；Along the direction of 3 oil return of oil return line
It is sequentially arranged with flow monitor A7 and return filter 8；It is sequentially arranged with motor pump group 9, list along the fuel-displaced direction of oil outlet pipe 3
To valve 10 and flow monitor B11；Equipped with for returning to babinet 1 in motor pump group 9 to the oil outlet pipe between check valve 10
Branch pipe A12, safety valve 13 is housed on branch pipe A12；It is filled on the check valve 10 to the oil outlet pipe between flow monitor B11
It is useful for returning to the branch pipe B14 of babinet 1, ball valve 15 is housed on branch pipe B14；The liquid-level switch 6 and flow monitor A7, flow
Monitor B11 communicates to connect controller 2, and controller 2 carries out real-time control, wherein flow to the working condition of motor pump group 9
The flow of the hydraulic oil of monitor A7 monitorings indicates that the flow of the hydraulic oil of flow monitor B11 monitorings is indicated with Q2 with Q1.
Pressure gauge A16 and pressure switch A17 is housed in the present embodiment on oil return line 3, is equipped in oil outlet pipe 4
Pressure gauge B18 and pressure switch B19, wherein pressure gauge A16, pressure switch B18 read oil return in real time convenient for staff
Oil pressure on pipeline 3 and oil outlet pipe 4, to prevent oil pressure excessively high；It is set when the oil pressure on oil return line 3 or oil outlet pipe 4 reaches
When definite value, corresponding pressure switch A17 or pressure switch B19 can send an electric signal on two oil circuits, make thereon
Electrical equipment (such as electromagnet) acts, and then makes oil circuit release, or control control motor pump group 9 is stopped, and is overloaded to prevent it.
Equipped with the temperature sensor 20 communicated to connect with controller 2 on babinet 1 described in the present embodiment；On the side of babinet 1
Side is equipped with coupled logical liquid level gauge 21；Oil absorption filter 22 is housed in the arrival end of oil outlet pipe 4.
In the present embodiment, the liquid-level switch 6 of upper, middle and lower three selects float type level switch, and realizes in babinet 1
The monitoring of liquid level, when the liquid level in babinet is less than the minimum liquid level set or higher than the highest liquid level of setting, controller 2 can
The corresponding on-off model of return is received, and real-time control is carried out to the start and stop state of motor pump group 9.When shield debugging and
When driving operation, start and stop point can also be automatically selected.
Safety valve 13 described in the present embodiment is for preventing motor pump group 9 from overloading.
Check valve 10 described in the present embodiment causes motor pump group 9 to invert, pipeline oil for preventing loine pressure excessively high
Reflux, fluid overflow.
In the present embodiment, when needing detaching pipelines, ball valve 15 is opened, hydraulic pressure of pipe line oil is flowed back in babinet 1, avoided automatically
Waste.
The concrete operating principle of the utility model is as follows：
When shield starts driving, the liquid level in babinet 1 is begun to ramp up, when liquid level rises to middle liquid level（In being arranged in
The on-off model that the liquid-level switch 6 in portion returns is known）When, controller 2 controls motor pump group 9 and starts automatically, will be in babinet 1
Hydraulic oil is sent to ground hydraulic station.
If at this point, flow Q1<Q2, then 1 liquid level of babinet will constantly decline, when liquid level drops to low liquid level（By being arranged in
The on-off model that the liquid-level switch 6 of lower part returns is known）When, controller 2 controls motor pump group 9 and is automatically stopped, and prevents gear
Pumping is empty.
If flow Q1>Q2, then 1 liquid level of babinet will continue to rise, when liquid level rises to high liquid level（By being arranged in top
The on-off model that liquid-level switch 6 returns is known）When, transfer fuel tank can send out an alarm signal and give shield-tunneling construction personnel, shield
Structure construction personnel can make flow Q1 by reducing fltting speed<Q2 prevents hydraulic oil in babinet 1 from overflowing, to ensure shield
Continue to tunnel, if shield-tunneling construction personnel cannot temporarily be handled, shield structure jack will be automatically stopped after 2min, to influence
Driving.In order to avoid such thing occurs, the flow monitor B11 in the utility model can also be monitored by detection flows
The flow of device A7 automatically controls its flow flowed through, i.e., when shield driving excessive velocities, the flow Q1 of flow monitor A7>Stream
The flow Q2 of monitor B11 is measured, flow signal can be transferred to controller 2 by flow monitor B11 at this time, and controller 2 is fed back again
To host computer, PC control shield driving speed reduces, and ensures Q1<Q2 keeps shield driving unaffected.
The place of shield launching occupancy is greatly saved when carrying out the construction of shield separate launching in the utility model, reduces
Influence of the shield-tunneling construction to surrounding enviroment allows the construction of shield separate launching to become simple, conveniently, is achieved for projects good
Good economic benefit and social benefit.
