Prismatic drilling rod removes interior six side's connectors；
(3) it is inserted into bevel gear outer end face in six side's card slots using outer hexagon, driving bevel gear rotation, bevel gear rotation
Turn to drive toothed disc rotation, three claws being threadedly coupled with toothed disc pass through a guide rail hole and are radially displaced outwardly, block
Pawl further presses borehole wall outward and snaps fit onto hole wall, thus the positioning in drilling by anti-collapse hole sleeve；
(4) outer six ribs driving member then is passed through using cylindrical drilling rod and anti-collapse hole sleeve continues up drilling, cylindrical drilling rod
One section connects a section, stops drilling machine after 10 meters of depths are got in drilling, extracts cylindrical drilling rod out；
(5) it is inserted into upper anchor fluke bottom groove using straight-bar, the high-strength steel wire that allows of a 10000mm long is connected on anchor fluke
Rope, straight-bar are extend into drilling after sequentially passing through outer six rib driving members and anti-collapse hole sleeve upwards with anchor fluke, until by anchor fluke
Straight-bar is extracted out after pushing up to 10 meters of depth, and outside anchor fluke under the action of hangnail steel disc, anchor fluke is securely seated between in drilling；
(6) high-strength two anchor flukes for allowing compressed steel cord that will successively be connected with 6000mm and 2000mm according to the process of step (5)
It pushes into drilling and fixed；
(7) then by three it is high-strength allow compressed steel cord to respectively penetrate in left casing, right casing and setting of casing, on cased
End is protruded into and is threadedly coupled in the internal thread hole of outer six ribs driving member, then by three springs be respectively put into left casing,
In right casing and setting of casing, by three it is high-strength allow compressed steel cord to be separately connected baffle, make three it is firm allow compressed steel cord be in
Tight state simultaneously makes spring be in compressive state；
(8) mechanical jingle bell and fluorescent bands device of warning are installed to and left casing left end, right casing right end and bottom of the tube of trapping
And it is connect with baffle；
(9) it is high-strength to allow compressed steel cord be by tensioning, the high-strength compressed steel cord that allows when reinforcing soft broken coal rock body deep basic point absciss layer occurs
Baffle is pulled to overcome the elastic force of spring, the slide plate on left casing moves right along left casing, and the slide plate on right casing is along right casing
It is moved to the left, the slide plate on setting of casing is moved up along setting of casing, and when reinforcing soft broken coal rock body deep, basic point absciss layer amount, which reaches, faces
When dividing value, i.e., after slide plate is moved to certain position, touches mechanical jingle bell and fluorescent bands are warned device, thus automatic jingle bell alarm
And discharge fluorescence warning band simultaneously, can measure middle part basic point in drilling respectively, caused by superficial part basic point and deep basic point from
Layer amount.
