Core, to be used for various researchs.
Description of the drawings
Fig. 1 is the sectional view that column core of the present invention drills through target drill；
Fig. 2 is that column core of the present invention drills through the stereogram after the hemisection of target drill.
Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is further described.
It please refers to Fig.1 and Fig. 2, the embodiment provides a kind of column cores to drill through target drill, for piercing
Core is sampled rock mass, includes mainly shell 8 and the cavity zone 2 through the shell 8.
The shell 8 is tubular, has a certain thickness shell wall, and the upper surface of the shell 8 uniformly sets that there are six bore
Knife 1, the angle between adjacent two drill 1 is 60 °, and the outside of each drill 1 is concordant with the outer wall of the shell 8,
The drill 1 is pierced for fragmented rock body in the core of rock mass.As needed, the quantity of the drill 1 appropriate can increase
Subtract, is not limited with six.
The upper area of 8 inner wall of the shell is equipped with the cut through 81 that is protruded out to the cavity zone 2, in the cavity zone 2
It is blocking district 21 by the circular area of the cut through 81, remaining area is sample region 22, and the blocking district 21 is located at the cavity zone
At 22 upper end opening, the connection external world and the sample region 22.It is stretched into from the blocking district 21 by the rock sample that the drill 1 drills through
The sample region 22 is filled up completely or is partially filled with the sample region 22.The cavity zone 2 is up-narrow and down-wide, to facilitate rock sample
Into.Since the aperture of the blocking district 21 is less than the aperture of the sample region 22, so the blocking district 21 and the sampling
The intersection in area 33 has a shoulder, preferably inner wall of the shoulder perpendicular to the shell 8.One guard rails 5 are removably pacified
Lower end loaded on the shell 8, the lower ending opening for blocking the cavity zone 2, the guard rails 5 only cover described
The regional area of 8 lower end of shell.The lower surface of the guard rails 5 is equipped with the coupling bar 7 for being connect with drilling machine, the drilling machine
Column core of the present invention is driven to drill through target drill work.
8 inner wall of the shell is equipped with damping layer 4, and the damping layer 4 supports the shoulder, supports the tail portion downwards upwards
Baffle 5.The damping layer 4 is made of elastic material, and has certain thickness, since column core drills through target drill work
Vibration more violent Shi Huiyou, the damping layer 4 can prevent some short samples after entering the sample region 22 because shaking
Situation dynamic and that fracture or damage occurs occurs, to improve the quality of sampling.It is preferred that the damping layer 4 be it is cost-effective and
Cystosepiment that is light, being easy to get.
Several hydraulic pressure holes 3 are pierced from the lower end of the shell 8 inside the shell 8 upwards, then wear out the shell 8
Inner wall and the damping layer 4 are connected to the upper area of the cavity zone 2, and there are four the tools of hydraulic pressure hole 3, but also not with this
It is limited.
The lower end in each hydraulic pressure hole 3 connects a high pressure water interface 6, and the high pressure water interface 6 protrudes out the shell
8, and positioned at 8 lower end of the shell by the guard rails cover with exterior domain, the upper end in the hydraulic pressure hole 3 is cut close to described
Disconnected portion 81 and tilt upward setting, the cavity zone of the high pressure water penetrating in the hydraulic pressure hole 32 to by rock sample from the sampling
The boundary of area 22 and the blocking district 21 blocks.
In use, the drill 1 pierces in rock mass, the rock sample in rock mass enters the sample region by the blocking district 21
22, the rock sample positioned at the sample region 22 is protected by the damping layer 4 and is not susceptible to fracture or damage, and the high pressure is passed through
Water interface 6 injects high pressure water into the corresponding hydraulic pressure hole 3, and high pressure water is sprayed by the upper end in the hydraulic pressure hole 3, impactite
Sample makes rock sample be blocked from the boundary of the sample region 22 and the blocking district 21, to which acquisition is positioned at the acquisition zone 22
Rock sample dismantles the guard rails 5, and collected rock sample is made to be poured out from the lower end of the sample region 22, to complete to sample.
Column core of the present invention drills through the rock-like that target drill can be used for a variety of occasions such as under mine and mine
Product acquire.Target drill is drilled through by using column core of the present invention, complete core can be taken out, it is various to be used for
Research.
Herein, the nouns of locality such as involved front, rear, top, and bottom are to be located in figure with parts in attached drawing and zero
Part mutual position defines, only for the purpose of expressing the technical solution clearly and conveniently.It should be appreciated that the noun of locality
Use should not limit the claimed range of the application.
In the absence of conflict, the feature in embodiment and embodiment herein-above set forth can be combined with each other.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
