Fixed, after being inserted into certain distance, the ladder position butt end of erection joint 19 can contact that (both i.e. formation interference is matched with pressing plate 9
It closes)；
(3) entirety after connection is put into institute 24 hole of deep hole to be mounted, anchor fluke fixed diameter after being unfolded due to anchor fluke
More than bore dia, the holding section 25 of claw 5 contacts with aperture but cannot enter in hole, therefore need a level pressure when mounted
Power can be just installed in hole.
Anchor fluke device is with installation tool variation in detail when being installed to deep hole：
The holding section 25 of claw 5 be fulcrum, continue into a distance pressing plate 9 continue decline can compress compression spring 10, simultaneously
The pyramidal structure on the mounting jaw top of erection joint 19 can be in contact with the first buckle 8 with the 17 composition conical surface of the second buckle, and first
For elastic construction, its elastic force can prevent erection joint 19 from being further inserted into buckle 8 with the 17 composition conical surface of the second buckle, at the same time,
The decline of pressing plate 9 can push guide rod 13 to decline, and guide rod 13 declines, and is connect by arcwall face of 12 pulling force of tension spring tightly with guide rod 13
The spherical structure of tactile claw 5 can be slided from the smooth arc transiting surface major diameter position of guide rod 13 to path position, claw 5 with
Claw rotating bar 15 is rotated for the center of circle, and holding section 25 moves inward, and the fixed outer diameter of circle that the holding section 25 of claw 5 is formed subtracts
It is small；
(4) if 25 fixed outer diameter of holding section of claw 5 needs bigger pressure that can just be installed to still greater than orifice diameter at this time
In hole, when increase is applied to the pressure of pressing plate 9, pressing plate 9 continues to decline at this time, further holddown spring, while erection joint 19
31 top of mounting jaw pyramidal structure can with first buckle 8 with second buckle 17 form the conical surfaces become squeezing from contacting, first
The elastic construction of 8 and second buckle of buckle, the 17 composition conical surface, elastic construction can extend out under pressure, erection joint 19 into one
Step is inserted into inside anchor fluke device, and at the same time, the decline of pressing plate 9 continues to press on guide rod 13 and declines, and guide rod 13 declines, by drawing
5 spherical structure of claw that 12 pulling force of spring is tightly contacted with the arcwall face of guide rod 13 can be from the arcwall face major diameter position of guide rod 13
Continue to slide to path position, claw 5 is rotated with claw rotating bar 15 for the center of circle, and claw 5 continues to move inward, on claw 5
The fixed outer diameter that holding section 25 is formed further reduces；
(5) continue to increase the pressure to anchor fluke device center platen 9, be gradually reduced the fixation that holding section 25 is formed on claw 5
Outer diameter is installed to until by anchor fluke device in hole, holds connecting rope 6 and connecting rope 21 at this time by rationally controlling two connecting ropes
Anchor fluke device is installed to wanted installation site by subsidence velocity；
(6) high resistance (entering rubble plug-hole in such as hole) is encountered as installed at this time, is needed at this time by the weight of entire mounting rod
Power increases on pressing plate 9.According to design, pressing plate 9 can be pressed onto bottom limit position by the dead weight of mounting rod 20, erection joint at this time
The pyramidal structure on 19 mounting jaw top can cross 17 composition conical surface elastic construction of the first buckle 8 and the second buckle, the first buckle 8
It is nature with 17 rebound of the second buckle, the pyramidal structure on 19 mounting jaw top of erection joint is stuck；13 bottom of guide rod
It can be contacted with 1 interior design small boss pilot hole bottom of lower cover, guide rod 13 be prevented to continue to move down, guide rod 13 drops at this time
Extreme lower position, 5 spherical structure of claw tightly contacted by 12 pulling force of tension spring with the arcwall face of guide rod 13 can be from guide rod 13
To most path position, claw 5 is rotated by the center of circle of fixing axle for smooth arc transiting surface major diameter position activity, then claw 5 to
Medial movement, the fixed outer diameter that holding section 25 is formed on claw 5 at this time is minimum and outer diameter is less than aperture at this time；Due to the first buckle
8 and 17 rebound of the second buckle for nature, by the pyramidal structure on 19 mounting jaw top of erection joint is stuck and fixed outer diameter most
It is small and at this time outer diameter be less than aperture, easily anchor fluke device can be fetched with mounting rod by two connecting ropes out of hole.
(7) if installing successfully, at this time by pulling up connecting rope 21, installation tool is above put forward, in frictional force retardance and compression spring 10
It can move up pressing plate 9 under the action of upward elastic force, guide rod 13 and then moves up, the 5 spherical structure meeting of claw contacted with arcwall face
From the smooth arc transiting surface path position activity of guide rod 13 to major diameter position, claw 5 is rotated by the center of circle of fixing axle, claw
Holding section 25 is tightly secured in hole wall above 5, if feeling, fixation is unreliable, can keep connecting rope 6 motionless at this time and tense
Connecting rope 21 is fulcrum with the holding section 25 of claw 5, claw 5 is allowed to be turned out around rotation axis, then outer diameter further becomes larger, card
Conjunction portion 25 is more securely retained in hole.Continue to pull up connecting rope 21 until will be taken out out of deep hole in installation tool, entirely
Connecting rope 6 is held in the process, prevents connecting rope 6 from falling into hole, once because connecting rope 6 falls into deep hole, then sensor is with regard to nothing
Method is mounted with.Resilient sleeve 4 can be according to its pressure change of outer bound pair in installation process, and maximum outside diameter is more than hole under natural conditions
Diameter, therefore when being installed in hole, resilient sleeve 4 has small contraction trend.
It after installation is complete, is anchored, the process of anchoring is：
(1) Anchor Agent is not shunk with Manual grouting pump injection expansion.Anchor Agent is not shunk in expansion, by the silicic acid of 32.5 intensity
Salt cement, expansion rate are not less than 0.02% swelling agent, are matched with clear water.Water, cement, swelling agent mass ratio be 2:1:
0.12, total amount can seal 50cm height in about hole.Resilient sleeve 4 expands outwardly under the gravity of Anchor Agent at this time, while
Under the holding section 25 of claw 5 supports, Anchor Agent 23 is stopped, until sealing, Anchor Agent 23 can contact with hole wall and flow into hole wall
Gap is finally combined anchoring with hole wall.
(2) it if needing to install in same hole needs that deep anchor fluke dress is first installed if multiple anchor fluke devices carry out multiple spot monitoring
It puts, after installation has anchored, needs to carry out casing protection to connecting rope 6, will realize ready casing 22 at this time, and have a diameter larger than
