12. the outer water round-robin method of outer water circulation system of the TBM according to claim 11 with automatic control, special
Sign is: in step S1 and step S2, when interior water temperature sensor detects that interior coolant-temperature gage is lower, opening first manual lock
Valve (11), a part of water in water main line (34) flow into water outlet main road (34), and outer water enters the flow of cooler (34)
It reduces, Wai Shui and interior hydrothermal exchange are reduced；When interior coolant-temperature gage meter detects that interior coolant-temperature gage is higher, first manual gate valve is closed
(11), the outer water in water main line (34) fully enters cooler (34), and the flow that outer water enters cooler (34) increases, outer water
Increase with interior hydrothermal exchange, and then adjusts interior coolant-temperature gage.
13. the outer water circulation of outer water circulation system of 0 ~ 12 described in any item TBM with automatic control according to claim 1
Method, it is characterised in that: needed in step S1 and step S2 to cutterhead spray water the following steps are included:
S1.1: under normal circumstances, when needing to spray water to cutterhead, first manual ball valve (26) and booster pump (25) is opened, warms up water
Water in case (16) enters cutterhead water pipe through the first outlet pipeline (37)；
S1.2: when booster pump (25) breaks down, third manual ball valve (29), back water pump (18) and the second manual ball valve are opened
(17), the outlet pressure of back water pump (18) is adjusted by adjusting first manual gate valve (14), warms up the water in water tank (16) through second
Outlet pipeline (38) and water return pipeline (39) enter cutterhead water pipe.
