It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1 to 3, an anchoring medicated roll according to an embodiment of the present invention includes an inner core daub column 1, a middle layer anchoring agent layer 2 and an outer layer daub layer 3, which are wrapped with a film.

The middle layer anchoring agent layer 2 is coated on the inner layer daub column 1, and the outer layer daub layer 3 is coated on the anchoring agent layer.

The anchoring cartridge provided by the utility model is a mixed cartridge, and the anchoring agent and the daub are combined together. Specifically, the anchoring cartridge comprises an inner core daub column 1, a middle layer anchoring agent layer 2 and an outer layer daub layer 3. The inner core daub column 1, the middle layer anchoring agent layer 2 and the outer layer daub layer 3 are respectively packaged by films, namely the inner core daub column 1, the middle layer anchoring agent layer 2 and the outer layer daub layer 3 are respectively coated with a thin film layer, so that the inner core daub column 1, the middle layer anchoring agent layer 2 and the outer layer daub layer 3 are respectively wrapped by the films, and the inner core daub column 1, the middle layer anchoring agent layer 2 and the outer layer daub layer 3 can be prevented from being exposed. When the combination is carried out, the inner core daub column 1 packaged with the film is positioned in the center, the middle layer anchoring agent layer 2 packaged with the film surrounds the outer side of the inner core daub column 1, and the outer layer daub layer 3 packaged with the film surrounds the outer side of the middle layer anchoring agent layer 2.

The inner core mastic column 1 is a mastic column or a mastic core made of existing mastic, which is innermost and is therefore referred to as the inner core mastic column.

The middle layer anchoring agent layer 2 is a ring of anchoring agent made of an existing anchoring agent, which is in the middle, and thus is called a middle layer anchoring agent layer.

The outer layer of mastic 3 is a mastic ring made of existing mastic, which is on the outermost side and is therefore referred to as the outer layer of mastic.

The inner side and the outer side of the middle layer anchoring agent layer 2 are both made of daub, when stirring, the anchoring agent can be contacted with and mixed with the daub on the inner side, the contact area is large, full reaction can be achieved easily during stirring, and further the anchoring effect is enhanced.

When the anchor stick is used, the anchor stick is placed at a designated position in a drill hole, and when the anchor stick or the anchor cable is installed, the anchor stick or the anchor cable moves towards the drill hole and rotates, so that the anchor stick is extruded and stirred, the anchor agent and the daub are mixed and react, and the daub is arranged on the inner side and the outer side of the anchor agent, so that the anchor agent and the daub are mixed and react more easily, and the anchoring effect is enhanced.

In one embodiment, the inner core mastic column 1, the middle layer anchor layer 2 and the outer layer mastic layer 3 are each enclosed in a film bag.

The film bag can be plastic film bag. The inner core cement column 1 is placed in a plastic bag and then sealed, so that the inner core cement column 1 is conveniently packaged. The middle anchoring agent layer 2 is placed in a plastic bag and then sealed, so that the middle anchoring agent layer 2 is conveniently packaged. The outer layer of the daub layer 3 is placed in a plastic bag and then sealed, so that the outer layer of the daub layer 3 is conveniently packaged.

In one embodiment, as shown in fig. 1-3, the middle anchoring agent layer 2 includes a first anchoring agent layer 21 and a second anchoring agent layer 22.

The first anchor agent layer 21 is on the side of the second anchor agent layer 22 in the axial direction along the core cement column 1.

The first and

second anchor layers

21 and 22 may be wrapped together by a thin film, but the first and

second anchor layers

21 and 22 are not mixed. The first anchor agent layer 21 extends from the middle toward one end of the core cement column 1, and the second anchor agent layer 22 extends from the middle toward the other end of the core cement column 1.

The solidification rate of the anchoring agent in the first anchoring agent layer 21 is different from the solidification rate of the anchoring agent in the second anchoring agent layer 22. The solidification rate of the anchoring agent in the second anchoring agent layer 22 is faster than the solidification rate of the anchoring agent in the first anchoring agent layer 21. In use, the second anchoring agent layer 22 is placed to the bottom of the hole with the first anchoring agent layer 21 facing the aperture. When installing the anchor rod or cable in the borehole, the anchor rod or cable may first stir the section of the first anchoring agent layer 21 and then stir the second anchoring agent layer 22. That is, in this process, the stirring time of the anchor in the first anchor layer 21 is longer than the stirring time of the anchor in the second anchor layer 22. If the solidification rate of the anchor in the first anchor layer 21 is the same as that of the anchor in the second anchor layer 22, the anchor in the second anchor layer 22 does not achieve the desired effect when the anchor in the first anchor layer 21 is stirred to solidify. If the solidification rate of the anchoring agent in the second anchoring agent layer 22 is faster than that of the anchoring agent in the first anchoring agent layer 21, the anchoring agent in each part can be sufficiently reacted, and the anchoring effect of the anchoring agent can be sufficiently exerted.

In one embodiment, the first anchoring agent layer 21 and the second anchoring agent layer 22 are separated by a film, so that the first anchoring agent layer 21 and the second anchoring agent layer 22 are prevented from contacting and mixing to influence each other.

In one embodiment, the first and second anchoring agent layers 21 and 22 are each enclosed in a film bag.

The film bag can be plastic film bag. The first anchoring agent layer 21 is placed in a plastic bag and then sealed, facilitating encapsulation of the first anchoring agent layer 21. The second anchoring agent layer 22 is placed in a plastic bag and then sealed, facilitating encapsulation of the second anchoring agent layer 22.

In one embodiment, as shown in fig. 1, the lengths of the first anchoring agent layer 21 and the second anchoring agent layer 22 are equal, so as to avoid that the anchoring effectiveness of the second anchoring agent layer 22 is influenced by the time lag of stirring due to the too short length of the second anchoring agent layer.

In one embodiment, the ends of the inner core mortar column 1, the middle layer anchoring agent layer 2 and the outer layer mortar layer 3 are fastened, so that the two ends of the inner core mortar column 1, the middle layer anchoring agent layer 2 and the outer layer mortar layer 3 are sealed and fastened, and the inner core mortar column 1, the middle layer anchoring agent layer 2 and the outer layer mortar layer 3 are prevented from being separated.

In one embodiment, as shown in fig. 1, the ends of the inner core mastic column 1, the middle layer of anchor 2 and the outer layer of mastic 3 are fastened together by ties 4. The ribbon 4 can adopt the existing lock catch with a self-locking structure, so that the ends of the inner core cement column 1, the middle layer anchoring agent layer 2 and the outer layer cement layer 3 are conveniently fastened together.

In one embodiment, the ends of the inner core mastic column 1, the middle layer anchor layer 2 and the outer layer mastic layer 3 are fastened by adhesive tape. The adhesive tape can adopt a single-sided adhesive film, and the end parts of the inner core adhesive pillar 1, the middle layer anchoring agent layer 2 and the outer layer adhesive layer 3 can be bonded together, so that the fastening is realized.

In one embodiment, the two ends of the inner core cement column 1, the middle layer anchoring agent layer 2 and the outer layer cement layer 3 are respectively shrunk to be thin, which is beneficial to realizing the closing and tightening of the end parts of the inner core cement column 1, the middle layer anchoring agent layer 2 and the outer layer cement layer 3.

In conclusion, the anchoring cartridge provided by the utility model increases the contact area between the anchoring agent and the daub by configuring the inner core daub column 1, the middle anchoring agent layer 2 and the outer daub layer 3, and the anchoring agent can be fully mixed with the daub to react when being stirred by the anchor rod or the anchor cable, so that the anchoring effect is enhanced.

According to the needs, the above technical schemes can be combined to achieve the best technical effect.

The foregoing is considered as illustrative only of the principles and preferred embodiments of the utility model.
