After the synchronous grouting of shield mechanism stops, slave computer proceeds by timing, and slave computer can be according to following within the T1 times
Three kinds of situations are judged：
Situation 1：Host computer sends the instruction of grouting pipeline cleaning, and slave computer stops timing and reset, and proceeds by Grouting Pipe
Road is cleaned；
Situation 2：Host computer slip casting again, timer stop timing and reset, and recover to slip casting the state before terminating；
Situation 3：Host computer does not carry out any operation, and when slave computer timing reaches the T1 times, host computer starts alarm signal, prompts
Equipment staff cleans to grouting pipeline in time, if now staff again slip casting or send grouting pipeline cleaning
Then slave computer stops timing and reset for instruction；If upper computer equipment continues unattended after the alarm T2 times, slave computer is automatic
Perform grouting pipeline cleaning；
When grouting pipeline is cleaned, slave computer is obtained in the grouting pipeline according to the pressure sensor set on grouting pipeline
Grouting pressure, and the control ball valve closed on the grouting pipeline, the control ball valve on bentonite filling line is opened, by swelling
In soil injection grouting pipeline, while the control ball valve on the connecting line between blowoff line and grouting pipeline is opened, this
When grouting pipeline on slip casting ball valve close, bentonite and remaining mortar enter blowoff line through connecting line, after S1min,
Slave computer sends control instruction and closes the control ball valve on bentonite filling line, and opens the pneumatic diaphragm on blowoff line
Pump, pneumatic diaphragm pump extract sewage and bentonite and remaining mortar are directed out into discharge by blowoff line or are expelled to sewage
Case, after S2min, slave computer sends control instruction and closes pneumatic diaphragm pump, and anti-according to the pressure sensor institute in foul water tank
The height of pressure value P is presented, judges whether that starting Pulp pump is transported to the waste liquid in foul water tank outside hole through blowoff line.
9. a kind of grouting pipeline as claimed in claim 8 cleans the control method of blowdown apparatus automatically, it is characterised in that：Work as gas
When dynamic membrane pump exhausts the waste water in shield casing, blowdown can be continued by the new water source of make-up water source interface introducing and moved
Make.
