Blind plate is blocked, it is ensured that after the water-filling of water curtain tunnel, water does not turn on to bottom and connects tunnel；
Step 4, when each oil storage cavern con struction completes after-pouring sealing-plug, export and set on the sealing-plug of side in underground engineering
Put manhole；
Step 5, after the completion of the sealing-plug is poured, manhole is only retained, in the bottom extension colligation of the waterpipe
Explosive, explosive lead is drawn by the manhole, and the manhole uses blind plate sealing；
Step 6, ignition charge, the bottom of the waterpipe is fried broken, temporary plugging structure is broken by way of explosion
It is bad, the water in the water curtain tunnel is conducting in the connection tunnel, finally the manhole is sealed using concreting.
Further, described two explosives of waterpipe bottom extension colligation, and two explosive spacing distances are more than
20cm。
Beneficial effects of the present invention are：
Water seal cave depot connection tunnel of the present invention and the water filling conducting device in water curtain tunnel, simple in construction, reliability
By force, it is water-filled simultaneously in water curtain tunnel by way of pre-buried water pipe road, do not influence bottom to connect the current effect in tunnel,
Water passage can be opened rapidly after the completion of sealing-plug is poured, it is to avoid the brought construction of drilling downwards is stranded from water curtain tunnel
Difficulty, reduces construction cost.
