Description

Technical Field

[0001] This invention relates to the field of gravel geological protection technology, and in particular to a mesh reinforcement device and method for gravel geological bodies. Background Technology

[0002] On gravel hills, due to their loose geology, landslides and other geological disasters are prone to occur during rainfall or earthquakes. Current techniques for protecting gravel hill slopes involve driving multiple anchor rods or cables into the slope, then tying wire mesh between them, and finally spraying concrete onto the mesh to form a protective wall. While this technique provides some protection, it suffers from two main technical problems: 1. Drilling holes for the anchor rods or cables requires the use of drill rods. After drilling, the anchor rods or cables are driven in for anchoring. However, due to the loose geology of gravel (especially sand and gravel), drilling is difficult, and hole collapse is common during the removal of the drill rods. This necessitates re-drilling, causing construction difficulties and severely impacting efficiency. 2. When excavating tunnels in gravel geological bodies, even after the protective walls are formed, although they can provide some protection, the gravel geological body is prone to deformation due to rainwater erosion or vibration disturbance. The tunnel face is prone to collapse, and the geological body at the top of the gravel body is prone to subsidence, endangering the tunnel body that has been constructed, and even inducing project failure. Summary of the Invention

[0003] The purpose of this invention is to provide a mesh reinforcement device and method for gravelly geological formations. This invention utilizes anchor bolts that are directly drilled into the slope of the mountain, preventing the bolts from being pulled out and thus avoiding hole collapse. Multiple anchor bolts arranged in a mesh pattern penetrate deep into the slope, providing direct internal mesh support to the gravelly geological formation and preventing internal collapse.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A mesh reinforcement device for gravel geological formations includes a support frame and anchor rods, wherein the anchor rods consist of end anchor rods and support anchor rods.

[0006] The end anchor rod has a tapered front end and a first internal thread at the rear end;

[0007] The front end of the support anchor rod has a first external thread that mates with the first internal thread, and the rear end of the support anchor rod has a first internal thread.

[0008] It also includes,

[0009] A mounting body fixed on a bracket, wherein a first bearing is fixedly installed inside the mounting body, and a connecting ring is fixedly installed inside the first bearing, wherein the inner hole of the connecting ring is polygonal;

[0010] The thrust rod has an outer surface that is polygonal and slides in the inner hole of the connecting ring. The thrust rod slides in the connecting ring and has a retaining ring that extends radially outward from the rear of the thrust rod. The front end of the thrust rod has a first external thread that mates with the first internal thread.

[0011] A vibration motor is connected to the mounting body to provide vibration and propulsion power to the push rod;

[0012] A hydraulic rod, wherein the cylinder body of the hydraulic rod is fixed on the mounting body, and the movable rod body of the hydraulic rod is fixed with a push plate sleeved on the tail of the thrust rod. The push plate has a through hole through which the thrust rod can pass but the retaining ring cannot pass.

[0013] A rotary power mechanism is used to drive the rotation of the connecting ring.

[0014] Furthermore, the end anchor rod, the support anchor rod, and the thrust rod are all hollow tubes. The internal threaded hole at the rear end of the end anchor rod is connected forward through the hollow tube to the outlet at the front end of the tapered part. The support anchor rod is axially open from front to back, and the thrust rod is open from front to back.

[0015] Furthermore, it also includes a high-pressure water pump and a high-pressure air pump. The high-pressure water pump is used to connect to the tail of the thrust rod to introduce high-pressure water into its internal cavity, and the high-pressure air pump is used to connect to the tail of the thrust rod to introduce high-pressure gas into its internal cavity.

[0016] Furthermore, it also includes a first pressure tube that can extend into the hollow cavity inside the end anchor rod, the support anchor rod, and the thrust rod. A conical first rubber plug is rotatably installed at the end of the first pressure tube. The conical first rubber plug can extend through the hollow cavity inside the end anchor rod, the support anchor rod, and the thrust rod and can partially extend into the conical part of the end anchor rod to seal it. The shaft end of the first pressure tube has a pressure channel that penetrates forward through the end of the conical first rubber plug. The surface of the anchor rod has multiple liquid outlet holes that communicate with its internal cavity.

[0017] Furthermore, it also includes a second pressure tube that can extend into the hollow cavity inside the end anchor rod, the support anchor rod, and the thrust rod. Two second rubber plugs are connected at intervals to the second pressure tube. The ends of the second rubber plugs are tapered. The second rubber plugs can slide within the hollow cavity inside the end anchor rod, the support anchor rod, and the thrust rod and can seal it. The second pressure tube and the anchor rod between the two spaced second rubber plugs are respectively provided with liquid outlet holes that communicate with the cavity inside the second pressure tube. The front end of the second pressure tube is closed.

[0018] Furthermore, anchor rods were driven into multiple points on the first slope of the mountain.

[0019] Furthermore, anchor rods are driven into the mountainside adjacent to the upper side or front and rear sides of the first slope, interspersed with the anchor rods of the first slope, so that the anchor rods form an interwoven mesh structure.

[0020] Further, the steps for driving in the anchor rod are as follows: Install the end anchor rod at the front end of the thrust rod, align the end anchor rod with the point to be implanted, turn on the rotary drive mechanism and hydraulic rod, and press the end anchor rod into the gravel slope while rotating. When most of the end anchor rod has entered the slope, stop the rotary drive mechanism and hydraulic rod, use a tool to position the end anchor rod so that it cannot rotate, and then start the rotary drive mechanism to rotate in the opposite direction, pulling the thrust rod out of the end anchor rod. Then move the thrust rod backward away from the end anchor rod, install the support anchor rod between the thrust rod and the end anchor rod, and then continue to rotate and press it into the slope. After pressing is completed, remove the thrust rod from the last section of the support anchor rod.

[0021] Furthermore, during the installation of the anchor rod, if the tapered part at the front end of the end anchor rod encounters gravel, it may be difficult to push it in. In this case, the vibration motor is turned on to vibrate and assist the tapered part of the end anchor rod to bypass the gravel or push the gravel away.

[0022] Furthermore, high-pressure gas or high-pressure water is introduced through the thrust rod, and the high-pressure gas or high-pressure water is ejected from the front outlet of the tapered part at the front end of the end anchor rod, which helps to advance the end anchor rod.

[0023] The beneficial effects of this invention are:

[0024] 1. By drilling the anchor rod directly into the gravel mountain body, which is prone to hole collapse, it can be used directly as an anchor rod after drilling without having to be pulled out. This solves the technical problem of hole collapse that occurs when drilling with a drill bit before anchoring with traditional anchors. Moreover, the anchor rod can be continuously extended as needed.

[0025] 2. During the drilling process of the anchor rod, the present invention uses a vibration motor to make the anchor rod vibrate, which makes it easier to overcome obstacles such as sand and gravel, which are difficult to pass through, and provides convenience for drilling deeper holes;

[0026] 3. High-pressure water or air can be introduced during drilling, which provides convenience when drilling encounters difficult situations;

[0027] 4. On the slope of a gravelly geological body, multiple adjacent anchor rods are driven in to form a network. The pebbles and other rocks within the gravelly geological body support and lift up the multiple anchor rods, making the mountain less prone to geological disasters such as landslides. In addition, grouting can be performed on the anchor rods. After grouting, the grout diffuses into the gravelly geological body around the anchor rods, forming a unified anchoring system between the numerous anchor rods and the gravelly body. This invention anchors the gravelly geological body from the inside, providing an excellent solution for the safety of gravelly geological bodies. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] This invention relates to a mesh reinforcement device and method for gravel geological formations. The reinforcement device includes a support frame 1, which can be pre-fixed at the construction site using hoisting equipment or scaffolding during construction. The support frame 1 is then placed on the scaffolding. The support frame 1 consists of a platform and four adjustable-height table legs. Alternatively, the platform and table legs can be rotatably connected, allowing adjustment of the platform's tilt by changing the length of some of the table legs.

[0050] After finding the drilling position, screw the first internal thread 4 at the rear end of the end anchor rod 2 into the first external thread 5 of the thrust rod 9. It should be noted that the first internal thread 4 and the first external thread 5 are engaged in such a way that when the rotating power mechanism drives the thrust rod 9 to rotate, the rotation direction is in the direction in which the first external thread 5 and the first internal thread 4 are tightened. Then, align the tapered part 201 of the end anchor rod 2 with the driving point on the mountain slope, and start the rotating power mechanism. The rotating power mechanism drives the thrust rod 9 to rotate, and the thrust rod 9 drives the end anchor rod 2 to rotate. At the same time, start the hydraulic rod 12, which is controlled by the hydraulic system. The hydraulic rod 12 pushes the thrust rod 9 to advance the end anchor rod 2 into the gravelly mountain slope. When the end anchor rod 2 is mostly advanced into the mountain, if it is necessary to increase the length of the anchor rod, the rotating drive mechanism and the hydraulic rod 12 can be stopped. Use a tool to position the end anchor rod 2 so that it cannot rotate. Then start the rotating drive mechanism to rotate in the opposite direction, pulling the thrust rod 9 out of the end anchor rod 2. Then push the thrust rod 9 away from the end anchor rod 2. Install the support anchor rod 3 between the thrust rod 9 and the end anchor rod 2, and then continue to rotate and press it into the mountain slope. If it is necessary to extend the anchor rod, repeat the above actions and connect the support anchor rod 3. After pressing is completed, the thrust rod 9 can be removed from the last support anchor rod 3. A protruding retaining ring 10 is provided at the rear end of the thrust rod 9. A push plate 13 is fixed to the movable rod of the hydraulic rod 12 and sleeved on the tail of the thrust rod 9. The push plate 13 has a through hole through which the thrust rod 9 can pass but the retaining ring 10 cannot. A thrust bearing 21 is fixed on the retaining ring 10. The push plate 13 pushes the thrust bearing 21, causing the thrust rod 9 to move forward in the direction of the through hole.

[0051] The minor diameter of the threaded hole formed by the first internal thread 4 is larger than the internal channel of the cylinder in which it is located (e.g., the hollow channel inside the end anchor rod 2).

[0052] The present invention also includes a vibration motor 11. The mounting body 6 is elastically mounted on the support 1. Specifically, the mounting body 6 consists of a platform and four elastic telescopic rods 22. The four elastic telescopic rods 22 are fixed between the platform and the support 1 to support the platform. Each elastic telescopic rod 22 consists of a first sleeve, a first movable rod slidably connected within the first sleeve, and a first spring located within the first sleeve, with its two ends connected to the first movable rod and the bottom of the first sleeve, respectively. The vibration motor 11 is fixed to the platform, preferably on the lower side of the platform. The elastic telescopic rods 22 connect the platform and the support 1, allowing the platform to vibrate with a large amplitude when the vibration motor 11 vibrates. This facilitates the rotation or swing of the anchor rod over obstacles. When the anchor rod is driven into a slope composed of gravel, if it encounters large rocks such as pebbles, it may get stuck or be difficult to drive in. In this case, activating the vibration motor 11 causes the end anchor rod 2 to have pushing, vibrating, and rotating actions, which helps the end anchor rod 2 to overcome pebbles and continue drilling.

[0053] If drilling is still difficult after the vibration motor 11 is started, a high-pressure water pump or high-pressure air pump can be connected to the tail of the thrust rod 9 through a rotary joint, so that the high-pressure airflow or high-pressure water flow is sprayed out from the outlet 14 at the front end of the tapered part of the end anchor rod 2, thereby breaking or driving away the pebbles and other obstacles that are blocking the progress.

[0054] The end anchor rod 2 in this invention has a tapered front end. Because the front end of the tapered part has a small area and the whole surface is inclined, it is beneficial to cross the rocks encountered during the drilling process.

[0055] A first internal thread 4 is provided at the rear of the end anchor rod 2, and a first external thread 5, which can be screwed into the first internal thread 4, is provided at the front end of the support anchor rod 3. The rear of the support anchor rod 3 also has a first internal thread 4. Multiple support anchor rods 3 can be connected sequentially as needed. The first external thread 5 of the support anchor rod 3 is screwed into the first internal thread 4 of the end anchor rod 2. Then, the first external thread 5 at the front end of the thrust rod 9 is screwed into the first internal thread 4 of the support anchor rod 3. The thrust rod 9 can then push the support anchor rod 3 and the end anchor rod 2 into the mountain slope. The outer surface of the thrust rod 9 is polygonal, preferably hexagonal. A through-hole is provided in the mounting body 6, and a first bearing 7 is fixed in the mounting hole. A connecting ring 8 is fixed inside the first bearing 7. The inner hole of the connecting ring 8 is a polygon that mates with the outer surface of the thrust rod 9. It can be hexagonal. The thrust rod 9 is inserted into the inner hole of the connecting ring 8. Then, the connecting ring 8 extends backward out of the mounting hole of the mounting body 6, and the first synchronous pulley 23 is mounted on the extended part. The rotation drive mechanism is a forward and reverse geared motor 24. A second synchronous pulley 25 is mounted on the power output shaft of the forward and reverse geared motor 24. The forward and reverse geared motor 24 can be mounted on the mounting body 6. At this time, the second synchronous pulley 25 of the forward and reverse geared motor 24 and the first synchronous pulley 23 of the connecting ring 8 are connected together by a synchronous belt 26. The forward and reverse geared motor 24 can drive the thrust rod 9 to rotate. Of course, the forward and reverse geared motor 24 can also be fixed on the bracket 1. In this case, since there is a vibration motor 11 on the mounting body 6, the mounting body 6 may vibrate with the thrust rod 9. Therefore, a tensioning wheel structure 27 also needs to be installed on the bracket 1. This structure consists of a fixed rod 2701 fixed on the bracket 1, a spring telescopic rod 2702, a connecting rod 2703, and a third synchronous pulley 28. The spring telescopic rod 2702 consists of a second sleeve fixed on the fixed rod 2701, a second spring fixed at the bottom of the second sleeve, and a second movable rod connected to the other end of the second spring. The second movable rod slides inside the second sleeve. The connecting rod 2703 is connected to the second movable rod, and the third synchronous pulley 28 is rotatably connected to the connecting rod 2703. At this time, when connecting, the synchronous belt 26 needs to be sequentially placed on the connecting ring 8, the drive shaft of the forward and reverse geared motor 24, and the synchronous pulley on the connecting rod 2703. In this way, when the connecting ring 8 shakes, the spring telescopic rod can extend and retract, ensuring the tension of the synchronous belt while allowing the connecting ring 8 to shake.

[0056] As an example, during drilling, it is sometimes necessary to inject grout into the borehole so that the grout penetrates into the soil, filling the voids and creating a solidification effect, thereby improving the stability and bearing capacity of the gravel geological body. At this time, multiple grout outlet holes 18 are opened on the outer circumference of the end anchor rod 2 and the support anchor rod 3, connecting to their internal cavities. If high-pressure water or high-pressure airflow needs to be sprayed from the end of the anchor rod during drilling, a first pressure pipe 15 is required. A first rubber plug 16 is installed at the front end of the first pressure pipe 15 via a rotary joint. The front end of the first rubber plug 16 is conical. When it is necessary to spray high-pressure water or air at the front end of the end anchor rod 2, since the anchor rod in this embodiment is provided with a liquid outlet 18, if high-pressure air or water is directly introduced from the tail of the anchor rod, it will spray out from the liquid outlet 18. At this time, a mechanism consisting of a first pressure tube 15 and a first rubber plug 16 is required. The first rubber plug 16 is inserted into the thrust rod 9, and then pushed into the tapered part of the end anchor rod 2 through the first pressure tube 15, so that the tapered part of the first rubber plug 16 is squeezed into the tapered part of the end anchor rod 2. A pressure channel 17 is connected in the first pressure tube 15 and the first rubber plug 16. Therefore, when high-pressure air or water is introduced into the tail of the first pressure tube 15, the air will spray out from the first rubber plug 16 through the pressure channel 17, and then spray out from the outlet 14 of the tapered part of the end anchor rod 2. Since the first rubber plug 16, once inserted into the tapered part of the end anchor rod 2, will rotate with the end anchor rod 2 if rotation is required, a rotary joint connects the first rubber plug 16 and the first pressure pipe 15 to prevent the first pressure pipe 15 from rotating. When grouting is required after the anchor rod is drilled, the first pressure pipe 15 is pulled out of the anchor rod, the thrust rod 9 is disengaged from the last support anchor rod 3, and grout is injected into the last support anchor rod 3 through the grouting device. The grout flows out from the outlet hole 18 on the surface of the anchor rod and then seeps into the gravel soil layer. Grouting makes the gravel soil layer more stable. The outer diameter of the first pressure pipe 15 is smaller than the diameter of the inner cavity of the anchor rod.

[0057] As an example, when excavating a tunnel in a mountain, during the reinforcement of the gravel geological body using a mesh reinforcement method, for instance, we are reinforcing a slope on one side of the mountain, while the side to be excavated is perpendicular to that slope, and the tunnel is located within the area covered by our anchor bolts, such as... Figure 13As shown. At this point, our second pressure tube 19 and second rubber plug 20 structure are required. In this embodiment, two second rubber plugs 20 are connected at intervals on the hollow second pressure tube 19. The ends of the second rubber plugs 20 are tapered. A liquid outlet hole 18 is opened on the second pressure tube 19 between the two second rubber plugs 20. After the two second rubber plugs 20 enter the inner cavity of the anchor rod, they are positioned as needed, so that the distance between the two second rubber plugs 20 covers the transverse length of the tunnel cross-section. The liquid outlet hole 18 is pre-set on the anchor rod. After the anchor rod is anchored, the range of the liquid outlet hole 18 on the anchor rod at least covers the transverse length of the tunnel cross-section. The liquid outlet hole 18 inside the anchor rod communicates inward to the inner cavity of the anchor rod. The outer diameter of the second pressure tube 19 is smaller than the diameter of the inner cavity of the anchor rod. After the anchor rod is anchored, the second pressure pipe 19 is inserted into the predetermined position, and then grouting is performed on the pressure channel inside the second pressure pipe 19. The grout enters the cavity inside the anchor rod from the outlet hole 18 of the second pressure pipe 19, and then flows out into the soil through the outlet hole 18 on the anchor rod. Reinforcing and grouting above this section of the tunnel facilitates safe tunnel excavation.

[0058] Regarding the mesh reinforcement structure of this invention, as one mesh layout, anchor rods are spaced apart on the sloping surface of the gravelly geological body requiring reinforcement. These anchor rods are spaced apart and penetrate deep into the mountainside, protecting and reinforcing the gravelly geological body inside. Especially after grouting into the anchor rods, the grout seeps into the voids of the gravelly geological body, causing the gravelly geological body and the anchor rods to solidify together. Multiple anchor rods interact to form an overall reinforcement and support, thus fixing the gravelly geological body from within the mountain. As another mesh layout, anchor rods are driven into adjacent sides of the mountain, with the anchor rods on both sides arranged in an alternating pattern to form a mesh. This mesh structure provides support for the cobblestone geological body within the mountain, especially through grouting support, forming a unified support system.

[0059] During the drilling process of this invention, if a situation is difficult to penetrate, the obstacle in front can be flushed with high-pressure water or air to cause local collapse, thus facilitating continued drilling. If drilling is still difficult during flushing, the vibration motor 11 can be turned on to vibrate the anchor rod, thereby shifting the obstacle in front or the anchor rod itself. High-pressure air or water and vibration drilling can be carried out simultaneously.
