The registration of power table 19 is compared inspection, if roughly the same, shows that pressure is effective.
The application method of water control system is pressed based on the drilling single loop of overlying strata water flowing fractured zone detection, specific steps are such as
Under：
(1) construction drill 28：According to the construction element being pre-designed, constructed not in 24 region of rock mass to be measured using drilling machine 14
With the drilling 283~5 in orientation and inclination angle a, drill 28 a diameter of 89mm, and length is 70m or so, and clears up broken in drilling 28
Bits.
(2) equipment is installed：It is each that guide cone, front plugging device 30, tail portion plugging device 32, converter 6, communicating pipe 25 etc. are installed
Component, and it is sequentially connected drilling machine 14, drilling rod 12, high-pressure hose 13 and control operation console 33, it then utilizes drilling machine 14 that will block and surveys
Test system is transferred to the initial position of drilling 28.
(3) inspection of hermetic seal：It is first shut off the cock of water drain 15 of control operation console 33, opens master control switch 18, is surveyed to blocking
Test system provides detection hydraulic pressure, and closure Leakage Test is carried out to rubber bag tank 5, if without apparent drainage, carries out in next step
Otherwise operation returns to second step operation, checks the connection between each component and installation situation, then re-start third step operation,
Until qualified.
(4) pressure water observation is carried out：After inspection of hermetic seal qualification, packer permeability test is carried out, closure test system is made to be in initial bit
It sets, the cock of water drain 15 being re-closing off on control operation console 33 simultaneously opens master control switch 18, and high pressure is provided to test system is blocked
