Brief description of the drawings：
Fig. 1 is the process chart of the present invention.
Embodiment：
As shown in the figure：A kind of high hydraulic pressure big flow Karst Tunnel underground water seal blocking method, comprises the following steps：
1st, the spy water operation being engaged using physical prospecting and probing, determines hydraulic pressure and water.Leak is gone out according to the tunnel of exposure
Geological conditions data and hydrogeologic data that situation and design are provided, the water burst situation for water burst eastern section of being dashed forward to tunnel are divided
Analysis, determines mode, the position of physical prospecting and probing.Tunnel Gushing scope is further looked into reference to the physical detecting of progress
Visit, and carry out necessary probing work.Result of detection more than, determines the property of underground water water outlet and the position of water-yielding stratum
Put, scale.
2nd, the shunting and ejectment construction of leak are carried out out.It is big to single-point flow in constructing tunnel, pressure is high, flow velocity going out soon
Water spot, probing and physical prospecting are determined more than water-bearing layer position and property, it is determined that setting depth and setting by shunting decompression hole
Position；The order of closure is determined simultaneously, by the EXIT POINT near apart from water source gradually distally drainage, to reduce water pressure, drop
Low closure difficulty.
(1) construction in shunting decompression hole：Concentrated in tunnel in the range of water burst and enough shunting decompression holes are set, while
Certain water plugged by grouting hole is arranged on water outlet periphery, to create the execution conditions for blocking original issue., be according to thing in this stage
The result visited and drilled, using water source position as starting point, sets the shunting decompression hole of different depth and different angles, and install band
The shunting decompression pipe of high pressure valve, enables current to be discharged in the drainpipe with valve being embedded to, to reduce original EXIT POINT
The pressure of water and head.
(2) caisson ejectment construction (special shunting ejectment construction)：After the shunting of some tap holes, decompression, if failing
The condition of directly closure main channel is reached, then needs to be handled using the form of construction work (caisson) of special ejectment.Caisson
Purpose is not the lid weight and bearing capacity for increasing bottom plate water burst, and is easy for carrying out former issue scattered grouting treatment.For gushing
The characteristics of water spot water burst flow is big, after bottom plate high pressure consolidation and the construction of periphery tap hole are finished, removes in Limestone Cave Surge first
Charges or sediment, position upstream and downstream direction (or surrounding) fixedly secured several high pressure steels respectively are concentrated after cleaning out in water burst
Pipe carries out ejectment (ejectment steel pipe size is determined according to water yield), then makes centered on issue concrete caisson, caisson edge
There is center to be formed with the steel plate of draining slip casting orifice tube.Castingin orifice tube around caisson, beneficial to draining and follow-up plugging construction.Such as
