Description

Technical Field

[0001] The invention relates to the technical field of anchoring, and in particular to a resin anchoring agent packaging structure and an anchoring construction method. Background Art

[0002] Among many geotechnical anchoring technologies, resin-anchor (anchor cable) is a support component mainly composed of resin anchor and rod body. Its significant advantages are rapid curing and load-bearing, convenient construction, wide adaptability and low cost. It is widely used in soft rock tunnels because it meets the support requirements of soft rock tunnels. Resin anchor is the bonding medium between the anchor (anchor cable) and the anchor hole, and its bonding quality determines the anchoring performance of the resin anchor. The current resin anchor is a cement-like bonding material composed of unsaturated polyester resin, curing agent, and other materials, and the cement and curing agent are separated into two components by polyester film (packaging bag) for packaging. In the construction application of resin anchor, the packaging film needs to be broken and stirred by the anchor (anchor cable). If the packaging film is not effectively broken, the packaging film will cause the curing reaction of the resin anchor to be incomplete, that is, the glove effect. The glove effect will seriously weaken the anchoring force of the anchor, resulting in instability of the support structure and may even cause safety accidents. The current mainstream method to deal with the glove effect is to deploy additional cutting components on the anchor rod (anchor cable) to assist in breaking the resin anchor encapsulation film, but this method still has the risk of incomplete breaking of the film and fails to address the problem at its root.

[0003] In view of the shortcomings of the existing anchoring technology, the present invention provides a resin anchoring agent packaging structure and an anchoring construction method to improve the anchoring quality of the resin anchor rod (anchor cable). Summary of the invention

[0004] In view of the problem that the resin anchoring agent curing reaction is not completely completed when the encapsulated film is used, the present invention proposes a resin anchoring agent encapsulation structure and an anchoring construction method, which can make the reaction more complete and improve the construction quality by aggregating the film. The specific technical scheme is as follows: A resin anchor packaging structure includes a packaging film bag for containing the resin anchor, a traction hole is provided at the front end of the packaging film bag, and a fragile belt is provided at the rear end of the packaging film bag. The packaging film bag can be torn at the fragile belt when subjected to the spinning pressure of the anchor rod; it also includes a gathering device arranged at the front end of the packaging film bag, the gathering device includes a shell body that fits the outer circumference of the packaging film bag, a film shrinking platform and a clockwork spring assembly, the film shrinking platform is arranged in the shell body and separates the packaging film bag from the clockwork spring assembly, the clockwork spring assembly is connected to a traction belt, and the other end of the traction belt passes through the film shrinking platform and is connected to the traction hole; when the packaging film bag is not torn, the clockwork spring assembly generates a pulling force on the packaging film bag through the traction belt.

[0005] Furthermore, the fragile band is arranged in an annular shape on the circumferential outer wall of the rear end of the packaging film bag.

[0006] Furthermore, the clockwork spring assembly includes a packaging cap arranged at the front end of the shell, a clockwork shaft is coaxially installed in the packaging cap, a clockwork spring is provided between the clockwork shaft and the packaging cap, a winding wheel is arranged on the upper side of the clockwork spring, the winding wheel is connected to the clockwork shaft, a groove is provided on the winding wheel, and the traction belt is connected in the groove; after the packaging film bag is torn, the traction belt can be wound in the winding wheel under the rotation of the clockwork shaft.

[0007] Furthermore, the housing is divided by the film shrinking platform into a first housing part for mounting the clockwork spring assembly and a second housing part for mounting the front end of the packaging film bag, and a through hole is opened on the second housing part.

[0008] Furthermore, a collecting hole for the packaged film bag to pass through is opened at the center of the film shrinking station, and the traction belt passes through the collecting hole and has two ends respectively connected to the packaged film bag and the winding wheel.

[0009] Furthermore, the traction belt is made of elastic material.

[0010] An anchoring construction method, comprising the above-mentioned packaging structure containing a resin anchoring agent, comprises the following steps: S1. Drilling: Drilling holes in rock and soil using a drilling device; S2. Installation: Push the package structure containing the resin anchoring agent into the borehole of the rock and soil layer by the anchor trolley until the gathering device is located at the bottom of the borehole of the rock and soil layer; S3. Construction: The anchor rod is pushed and rotated by the anchor rod trolley. The crushing zone is torn under the spinning pressure of the anchor rod, and the energy stored in the clockwork spring is released to pull the packaging film bag into the gathering device.

[0011] The beneficial effects of the present invention are: 1. The spring and traction belt can gather the packaging film after the packaging film bag is torn, which solves the problem that the anchor packaging fragments affect the bonding and stirring and mixing effects of the anchor, and can make the anchor material more evenly mixed under the stirring action of the subsequent anchor rod body, effectively reducing the anchor failure caused by improper operation during the installation process.

[0012] 2. The shell of the aggregation device can provide an additional physical barrier for the packaging film at the end of the resin anchor when the resin anchor is pushed into the drill hole, preventing the packaging film from being accidentally damaged or scratched due to impact, friction or extrusion during the pushing process, thereby ensuring the integrity and effectiveness of the anchor.

[0018] The packaging structure also includes a gathering device 4 arranged at the front end of the packaging film bag 3, the gathering device 4 includes a shell 41 that fits the outer circumference of the packaging film bag 3, a film shrinking platform 42 and a clockwork spring assembly, the film shrinking platform 42 is arranged in the shell 41 and separates the packaging film bag 3 from the clockwork spring assembly, the clockwork spring assembly is connected to a traction belt 43, the other end of the traction belt 43 passes through the film shrinking platform 42 and is connected to the traction hole 32; when the packaging film bag 3 is not torn, the clockwork spring assembly generates a pulling force on the packaging film bag 3 through the traction belt 43.

[0019] Furthermore, the fragile band 31 is provided in an annular shape on the circumferential outer wall of the rear end of the packaging film bag 3 . The annular structure enables the packaging film bag 3 to be easily torn by the anchor rod 2 during spinning.

[0020] Furthermore, the clockwork spring assembly includes a packaging cap 47 arranged at the front end of the shell 41, a clockwork shaft 44 is coaxially installed in the packaging cap 47, a clockwork spring 46 is provided between the clockwork shaft 44 and the packaging cap 47, a winding wheel 45 is arranged on the upper side of the clockwork spring 46, the winding wheel 45 is connected to the clockwork shaft 44, a groove is provided on the winding wheel 45, and the traction belt 43 is connected in the groove; after the packaging film bag 3 is torn, the traction belt 43 can be wound in the winding wheel 45 under the rotation of the clockwork shaft 44.

[0021] Furthermore, the shell 41 is separated by the film shrinking platform 42 into a first shell part for installing the clockwork spring assembly and a second shell part for installing the front end of the packaging film bag 3. The first shell part is sealed by the packaging cap 47, and the second shell part is provided with a through hole, through which the resin anchor at the front end of the packaging film bag 3 can flow out, and the anchoring effect is better.

[0023] Furthermore, the traction belt 43 is made of elastic material to avoid being torn.

[0024] Second, as Figure 3As shown, the present invention provides an anchoring construction method, including the above-mentioned packaging structure filled with a resin anchoring agent, comprising the following steps: S1. Drilling: Drilling a hole in the rock and soil layer 1 using a drilling device.

[0025] S2. Installation: Push the packaging structure containing the resin anchoring agent into the borehole of the rock layer 1 by the anchor trolley until the gathering device 4 is located at the bottom of the borehole of the rock layer 1. There are two ways to assemble the packaging structure. One is to first rotate the spring 46 to make it in an expanded or contracted state, and then connect the traction belt 43 and the packaging film bag 3. At this time, the traction belt 43 is not wound on the winding wheel 45; the other is to first connect the traction belt 43 and the packaging film bag 3, and then rotate the spring 46 to make the traction belt 43 generate tension on the packaging film bag 3.

[0026] S3, construction: The anchor rod 2 is pushed and rotated by the anchor rod 2 trolley, the crushing belt is torn under the spinning pressure of the anchor rod 2, and the stored energy of the clockwork spring 46 is released to pull the packaging film bag 3 into the gathering device 4.

[0027] Taking downward drilling as an example, after drilling is completed, the packaging structure containing the resin anchoring agent is pushed into the drilled hole of the rock layer 1 until the gathering device 4 is located at the bottom of the drilled hole of the rock layer 1, and the tension of the traction belt 43, the friction between the packaging film bag 3 and the shell 41, and the material tension of the packaging film bag 3 itself are in a balanced state. After the packaging film bag 3 is torn, the tension disappears, and the stored energy of the clockwork spring 46 is released. The same is true for oblique downward drilling.

[0028] Taking upward drilling as an example, after drilling is completed, the packaging structure containing the resin anchor is pushed into the drill hole of the rock layer 1 until the gathering device 4 is located at the bottom of the drill hole of the rock layer 1. The tension of the traction belt 43, the friction between the packaging film bag 3 and the shell 41, the material tension of the packaging film bag 3 itself, and the gravity of the resin anchor are in a balanced state. After the packaging film bag 3 is torn, the tension and the gravity of the resin anchor disappear, and the stored energy of the clockwork spring 46 is released. The same is true for oblique upward drilling.

[0029] The clockwork spring 46 and the traction belt 43 can gather the packaging film after the packaging film bag 3 is torn, thereby solving the problem that the anchor packaging fragments affect the bonding and stirring and mixing effects of the anchor, and allowing the anchoring material to be more evenly mixed under the subsequent stirring action of the anchor rod 2, effectively reducing the anchoring failure caused by improper operation during the installation process.

[0030] The shell 41 of the gathering device 4 can provide an additional physical barrier for the packaging film at the end of the resin anchor when the resin anchor is pushed into the drill hole, preventing the packaging film from being accidentally damaged or scratched due to impact, friction or extrusion during the pushing process, thereby ensuring the integrity and effectiveness of the anchor.
