Technology is usually that drilling machine positioning is reinforced, and is then once crept into rock mass using drilling machine, orifice tube is installed, and carried out resistance to
Experimental examination is pressed, then to secondary drilling in rock mass, drilling rod is positioned and fastened after meeting water, by segment of drillpipe removal or whole
Removal closes water-blocking valve, slip casting, waits for repetitive cycling bored grouting to projected depth.The controlling difficulties of leting speeper technology be
In drilling process during spy water, if how high pressure ground water there is a situation where erupting, quickly and effectively controls and accelerates in time
Removal drilling rod, the linking for closing the links such as blowout hookup and water-blocking valve.
By to water conservancy, highway, mine, the high pressure ground water study on prevention of each underground construction industry such as coal, to upper
It states the device of every profession and trade use and after way researched and analysed, many engineerings is often laid particular emphasis on during leting speeper to drilling
The timely closing of the end valve of the control and device that are discharged in the process does not carry out the travel condition of drilling rod in drilling process
Analysis and research, and it is found by the applicant that following two states can occur in drilling process in drilling rod：One is acted in high pressure water
Under, lobbing by a small margin occurs in duct for drilling rod, and drilling rod is not formed along the parallel drilling in duct, under by high water pressure force effect
Bit freezing occurs after rigid contact between the various blowout hookups in drill bit front protruding parts and rear portion and obtains state；Another kind is drilling rod
After shifting, since drilling rod is in deflected condition, causes waterproofing device to form space three-dimensional bias in duct with drilling rod and tilt friendship
Location status is pitched, closing can not thoroughly be sealed by forming valve, and drilling rod can not fasten the state of removal.
Above two state greatly increases removal drilling rod and closes the effective time of water-blocking valve, then subsequent blowout prevention dress
Set the work such as closing and slip casting can not quick joining, under the effect of prolonged high pressure water, often result in follow-up many water
Flood tunnel event and other Derived Hazards.
