Row send water, and under the promotion of hydraulic pressure, inner tube assembly is constantly pushed, and until drill bit has water to return out, illustrates drilling tool in place（Bullet
Card holder 19 is sat on seat ring 203, is played clamp both wings and is stuck in spring card room 202, plays Ka Ding to centralizer end face and has 1mm activities
Amount）.
3rd, coring：Water swivel is removed, installation push connector, then proceedes to drill, the rock particles entered from drill bit is interior
Pipe 100 harvests, this point is as the prior art.
4th, drilling tool is salvaged：After the completion of coring, push connector is unloaded from drilling rod, while water swivel is installed, by steel wire rope
201 head is fixed with fisher, is specially：Worn by steel wire rope 201 since fixed pulley 420, then pass through the logical of power head 408
Hole, the steel wire rope being pierced by is connected with fisher rope card, in steel wire rope apart from one 100 length of inner tube of fisher distance（General 2
~ 3 meters）Place mark.Fisher is put into water swivel, ball valve is closed and opens slush pump（Steel wire rope one end）, by water
Handle fisher is pushed at inner tube assembly, when diamond bit returns water, is shown fisher and is dragged for the completion fixation of spearhead 1, this
When open water swivel ball valve, start the slow post-tensioning of winch, when being extracted with marked steel wire, stop winch work, armrest
Strength pull steel wire rope, until fisher is extracted, at this moment both hands pinch recovery hook afterbody, make fisher and drag for spearhead disengagement,
Inner pipe portion is pulled out by hand, takes out core.
Four more than repeating, whole coring is realized.
Other guide participates in the prior art.Above-described is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, this
It should also be considered as protection scope of the present invention a bit.
