Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of slope repair, and particularly relates to a mine slope ecological repair construction device. BACKGROUND

[0002] Mining is often accompanied by large-scale earthwork excavation, which directly changes the original topography and structure of the rock-soil body of the slope. The slope gradient, height and shape are artificially changed during the mining process, resulting in a significant reduction in the stability of the slope. Landslides, mudslides and other geological disasters caused by slope instability seriously threaten the safety of life and property of the surrounding residents.

[0003] The core principle of repairing the mine slope by using anchor rod fixed protection net is to stably connect the protection net on the mine slope by anchor rod, so as to enhance the overall stability of the slope. The first step of the mine slope protection construction is drilling, which needs to accurately determine the position, spacing and depth of the drilling hole according to the slope geological conditions, rock-soil body properties and protection net design requirements by using professional equipment; after drilling, the hole needs to be cleaned by high-pressure air or high-pressure water to remove the hole cuttings and sludge to ensure the anchoring effect of the anchor rod; then the anchor rod is vertically inserted into the hole and the insertion depth is ensured; then the cement mortar is pumped or self-flowed, and the mixing ratio and fluidity are controlled to ensure that the mortar is full, so that the anchor rod and the rock-soil body are tightly combined; after the mortar reaches a certain strength, the protection net such as steel wire rope net and metal grid net is unfolded to cover the slope, and is fixed with the anchor rod through the connecting piece to ensure that the protection net is flat and tight to achieve the protection effect.

[0004] In the construction process of the anchor rod fixed protection net, after the drilling is completed, the anchor rod needs to be inserted into the hole and the cement mortar needs to be poured to realize the tight anchoring of the anchor rod and the rock-soil body of the slope; due to the fluidity of the cement mortar, under the action of gravity, the liquid surface of the cement mortar poured into the inclined hole tends to be horizontal. When the liquid surface of the mortar is higher than the lowest point of the inclined hole, the excess mortar will flow out of the hole. The liquid surface of the mortar at the drilling opening position presents a horizontal state, and the opening of the drilling hole cannot be completely filled. With the continuous flow of the mortar, the part above the drilling hole gradually forms a cavity, which seriously affects the integrity and effectiveness of the anchoring of the anchor rod; at the same time, the existence of the cavity will weaken the anchoring force of the anchor rod; the anchoring force of the anchor rod mainly comes from the friction between the anchor rod and the hole wall and the adhesion of the mortar, and the existence of the cavity destroys this close combination state; gaps exist between the anchor rod and the mortar, which cannot form effective adhesion, so that the anchor rod cannot fully transmit the force to the surrounding rock-soil body when bearing external force. The stability of the slope protection system is reduced. SUMMARY

[0005] To overcome the shortcomings of existing technologies and solve the above-mentioned technical problems, this invention proposes a construction device for ecological restoration of mine slopes. By setting a fixing component, it can avoid the formation of voids above the mortar at the outlet of the injection hole, thereby preventing the existence of voids from weakening the anchoring force of the fixing component; the specific structure is as follows. A construction device for ecological restoration of mine slopes includes a fixing component; the fixing component is used to fix a protective net to the slope and to protect the slope using the protective net; The fixing component includes a tube with a conical bottom; the bottom of the tube has evenly distributed slots. A rotating ring is fixed above the trough by multiple sections; an injection tube rotates inside the rotating ring and extends to the top of the insert; a valve is fixedly installed at the top of the injection tube by threads. A push ring is provided above the rotating ring, and the inner ring of the push ring is threaded; the side of the injection tube that contacts the push ring is threaded and meshes with the thread of the inner ring of the push ring, and the part of the injection tube above the push ring is not threaded. The outer ring of the push ring is fixed with a slider; the inner ring of the insert is provided with a groove, and the groove does not extend to the top of the insert; the slider slides in the groove. The outer ring of the insert is threaded; a sealing disc is engaged with the outer ring of the insert, and the sealing disc is located at the top of the insert; a rubber ring is fixed to the bottom end face of the sealing disc; The sealing plate has an arc-shaped air groove; two upright plates are fixed above the arc-shaped air groove; a sealing block slides between the two upright plates, and the sealing block is initially staggered with the arc-shaped air groove.

[0006] In a preferred embodiment of the present invention, a mounting block is fixed to the top of the insert, and the insert is mounted on the drilling rig via the mounting block; A spiral drill bit is fixed at the bottom of the insert.

[0007] In a preferred embodiment of the present invention, the outer ring of the insert is provided with uniformly arranged vertical grooves, and the vertical grooves and sliding grooves are staggered. Each of the vertical slots has a rotating plate that rotates via a pivot, and the top of the rotating plate is conical and fits against the two sides of the vertical slot. A trapezoidal block is fixed to the side of the rotating plate facing the injection tube, and the side of the trapezoidal block facing the injection tube is arc-shaped.

[0008] In a preferred embodiment of the present invention, the rotating plate includes a sliding plate and a sliding cylinder, wherein the sliding plate slides within the sliding cylinder via a spring; The slide cylinder rotates within the vertical groove via a rotating shaft; the trapezoidal block is fixed on the slide plate; The top of the slide plate has a notch inside the insert, and the notch is connected to the outside of the insert; the top of the notch is an arc surface. The sliding plate extends into the notch under the thrust of the spring and abuts against the arc surface of the notch. The spring is compressed under the obstruction of the rotating plate. At the same time, the rotating plate is limited within the arc surface of the notch by the limiting force of the arc surface of the notch, and prevents the rotating plate from rotating into the insert.

[0009] In a preferred embodiment of the present invention, the slide cylinder is U-shaped; the width of the slide cylinder is the same as the width of the rotating plate, and both fit against the two sides of the vertical groove. The cavity inside the slide tube extends through both sides of the slide tube.

[0010] In a preferred embodiment of the present invention, a conical block is fixed to the surface of the rotating plate away from the injection tube.

[0011] In a preferred embodiment of the present invention, a T-shaped rod is fixedly installed on the top of the insert; An inverted L-shaped rod slides on the T-shaped rod, and part of the inverted L-shaped rod extends into the insert; a spring is provided above the inverted L-shaped rod, and the spring is sleeved on the T-shaped rod.

[0012] In a preferred embodiment of the present invention, a threaded rod is fixed to the bottom of the T-shaped rod; The top of the insert has a threaded groove, and the threaded rod is threaded into the threaded groove.

[0013] In a preferred embodiment of the present invention, the rubber ring is made of a water-absorbing and swellable rubber material; A rubber layer is fixed to the inner surface of the rubber ring, and the rubber layer is made of ordinary elastic rubber material; the cross-section of the rubber layer is L-shaped and fits the inner ring of the rubber ring and the bottom part area.

[0014] The beneficial effects of this invention are as follows: 1. The mine slope ecological restoration construction device of the present invention, by forming a complete space between the sealing plate, rubber ring and injection hole, allows the mortar to gradually fill the injection hole during mortar injection, and allows excess mortar to flow out from the arc-shaped air groove. This ensures that the mortar at the injection hole outlet is not horizontal and that no voids appear. Simultaneously, during the mortar injection into the insert, the push ring can be pushed upwards. When the push ring reaches the top, the mortar injected into the insert is not horizontal and no voids appear. This process avoids the mortar in the injection hole being horizontal, which could lead to voids above the mortar at the injection hole outlet. The presence of voids would weaken the anchoring force of the fixing components, preventing them from fully transmitting force to the surrounding soil and rock when subjected to external forces, thus reducing the stability of the slope protection system.

[0015] 2. The mine slope ecological restoration construction device of the present invention, during mortar injection, since the mortar is gradually injected from the bottom, as the mortar spreads upward from the bottom of the injection hole, it will naturally squeeze out the original air in the hole and discharge it through the arc-shaped air groove. In this process, it can avoid the situation where some gas remains in the mortar when the mortar is injected from the top, which would cause voids in the solidified mortar. At the same time, since there is a sealing plate and a rubber ring at the outlet of the injection hole, the outlet of the injection hole can be sealed, thereby preventing rainwater from flowing into the injection hole during later use, which would soften the hole wall and affect the fixing effect of the fixing components.

[0016] 3. The mine slope ecological restoration construction device of the present invention uses a sliding plate and a sliding cylinder inserted into the grouting hole as aggregate inside the mortar. The insertion cylinder can be fixed into a whole by the sliding plate and the sliding cylinder, which further enhances the stability of the overall mortar structure. When the rotating plate rotates, the mortar that has not been fully cured in the insertion cylinder can flow into the grouting hole through the vertical groove, filling the possible small gaps in the grouting hole and further filling the mortar in the grouting hole. At the same time, during the rotation of the rotating plate, it can drive the conical block to abut against the side wall of the grouting hole. When the mortar enters the sliding cylinder and cures, it will firmly lock the position of the rotating plate and the conical block, so that the conical block always maintains the abutment force against the side wall of the grouting hole, avoiding the problem that traditional anchors rely only on the mortar bonding force and are prone to a decrease in pull-out resistance due to mortar aging.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 14 As shown, the mine slope ecological restoration construction device of the present invention, as an embodiment of the present invention, includes a fixing component; the fixing component is used to fix the protective net to the slope and use the protective net to protect the slope; The fixing component includes a tube 1, and the bottom of the tube 1 is conical; the bottom of the tube 1 is provided with evenly arranged slots 191; A rotating ring 11 is fixed above the trough 191 by multiple sections; an injection tube 2 rotates inside the rotating ring 11 and extends to the top of the insert 1; a valve 21 is fixedly installed at the top of the injection tube 2 by threads. A push ring 22 is provided above the rotating ring 11, and the inner ring of the push ring 22 is threaded; the side of the injection tube 2 that contacts the push ring 22 is threaded and meshes with the thread of the inner ring of the push ring 22, and the part of the injection tube 2 above the push ring 22 is not threaded. The outer ring of the push ring 22 is fixed with a slider 23; the inner ring of the insert 1 is provided with a groove 12, and the groove 12 does not extend to the top of the insert 1; the slider 23 slides in the groove 12. The outer ring of the insert 1 is threaded; the outer ring of the insert 1 is threaded with a sealing plate 13, and the sealing plate 13 is located at the top of the insert 1; a rubber ring 14 is fixed to the bottom end face of the sealing plate 13. The sealing plate 13 has an arc-shaped air groove 15; two upright plates 16 are fixed above the arc-shaped air groove 15; a sealing block 17 slides between the two upright plates 16, and the sealing block 17 is initially staggered with the arc-shaped air groove 15. In this embodiment, the top of the insert 1 is fixed with a mounting block 18, and the insert 1 is mounted on the drilling rig via the mounting block 18; A spiral drill bit 19 is fixed at the bottom of the insert 1; During implementation, when repairing mine slopes, it is necessary to determine the location, spacing, and depth of boreholes based on the slope's geological conditions, soil and rock properties, and the design requirements of the protective netting, using specialized equipment. Once the borehole locations are determined, they are marked, and then drilling can be performed at the marked locations. After drilling is completed, a grouting hole will be formed. The slope at the grouting hole outlet area is then trimmed to ensure that the grouting hole and the trimmed slope are relatively perpendicular. Subsequently, the grouting hole is cleaned to remove rock cuttings and mud. Then, a fixing component with an appropriate diameter and length can be selected based on the diameter and depth of the grouting hole, ensuring that the diameter of the fixing component is smaller than the diameter of the grouting hole and the length of the fixing component is longer than the depth of the grouting hole. Specifically, after selecting the fixing component, it is first inserted into the grouting hole. Once inserted, the insert 1 is positioned in the middle of the hole, with the auger bit 19 at the bottom of the insert 1 resting against the bottom of the hole. Then, the mounting block 18 at the top of the insert 1 is clamped onto the drilling rig, and the drill hole drives the insert 1 to rotate. The rotating insert 1 drives the auger bit 19 at its bottom to rotate, gradually guiding it into the slope. Once inside the slope, the auger bit 19 is positioned and fixed within the mud or rock layer, thus securing the insert 1 within the grouting hole. Finally, the sealing plate 13 is fitted onto the top of the insert 1. The sealing plate 13 is rotated. Due to the thread engagement between the sealing plate 13 and the outer ring of the insert 1, the sealing plate 13 will gradually move downward along the insert 1 during the rotation of the sealing plate 13, and drive the rubber ring 14 to move downward. During the gradual downward movement of the sealing plate 13, the rubber ring 14 will fit against the slope of the outer ring of the injection hole, thereby sealing the opening of the injection hole between the rubber rings 14. When the rubber ring 14 is completely fitted against the slope, the sealing plate 13 is rotated again, and the position of the arc-shaped air groove 15 on the sealing plate 13 is adjusted so that the position of the arc-shaped air groove 15 is at the highest point. When the arc-shaped air groove 15 is located diagonally above the insert 1, the sealing plate 13 is stopped from rotating, and then mortar can be injected into the injection hole. More specifically, during grouting, the external grouting pipe is first connected to valve 21, and valve 21 is opened for grouting. During grouting, the grout enters the grouting pipe 2 through valve 21 and then flows out from the bottom of the grouting pipe 2. The flowing grout is located below the push ring 22. As the grout gradually fills the space below the push ring 22, since the push ring 22 is fixed by the thread, the grout filling the bottom of the push ring 22 will gradually flow out from the trough 191. The flowing grout will flow into the grouting hole. As the amount of grout in the grouting hole gradually increases, the liquid level of the grout in the grouting hole will gradually rise. The gas originally located in the grouting hole will gradually be discharged from the arc-shaped gas groove 15 as the grout gradually enters. Since the grout is a fluid, and the liquid... When the surface is horizontal, and the mortar in the injection hole rises to the lowest point of the injection hole outlet, the mortar will gradually come into contact with the rubber ring 14 and the sealing plate 13. As the mortar continues to be injected into the injection hole, the mortar in the injection hole will gradually fill the space formed by the injection hole, the rubber ring 14 and the sealing plate 13. Then the excess mortar will gradually enter the arc-shaped air groove 15. When the mortar flows out from the arc-shaped air groove 15, the mortar completely fills the injection hole, and the mortar at the injection hole outlet is not horizontal and there are no voids. Then the valve 21 is closed and the sealing block 17 is pushed towards the side of the insert 1. When the sealing block 17 is in contact with the insert 1, the arc-shaped air groove 15 is closed and the mortar no longer flows out from the inside of the arc-shaped air groove 15. Furthermore, the injection pipe 2 is then rotated. Since the push ring 22 slides within the groove 12 via the slider 23, the rotation of the injection pipe 2 pushes the push ring 22 upwards. When the push ring 22 moves above the thread, it is no longer limited by the thread. Then, the valve 21 is opened, and mortar continues to be injected. As the mortar continues to enter the space below the push ring 22, the arc-shaped air groove 15 is blocked, and the mortar in the injection hole will not continue to flow out. Therefore, the mortar flowing out from the bottom of the injection pipe 2 will accumulate in the insert 1 below the push ring 22. As the amount of mortar in the insert 1 gradually increases... The mortar gradually fills the space below the push ring 22, which will push the push ring 22 to move upward along the injection pipe 2. The push ring 22 will also drive the slider 23 to move upward along the slide groove 12. When the push ring 22 moves to the top position of the insert 1, the mortar below the push ring 22 will completely fill the space below the push ring 22 and fit with the push ring 22. At this time, the mortar injected into the insert 1 is not horizontal and there are no voids. Then stop injecting mortar into the injection pipe 2 and close the valve 21 to wait for the mortar to solidify. After the mortar is completely solidified, fix the protective net to different fixing components. Furthermore, by creating a complete space between the sealing plate 13, the rubber ring 14, and the injection hole, the mortar can gradually fill the injection hole during mortar injection, and excess mortar can flow out from the arc-shaped air groove 15. This ensures that the mortar at the injection hole outlet is not horizontal and there are no voids. Simultaneously, during the mortar injection into the insert 1, the push ring 22 can be pushed upwards. When the push ring 22 reaches the top, the mortar injected into the insert 1 is not horizontal and there are no voids. This process avoids the mortar in the injection hole being horizontal, which could lead to voids forming above the mortar at the injection hole outlet. This prevents voids from weakening the anchoring force of the fixing component, which would prevent the fixing component from fully transmitting force to the surrounding soil and rock when subjected to external forces, thus reducing the stability of the slope protection system. Meanwhile, during mortar injection, as the mortar is gradually injected from the bottom, it naturally compresses the air inside the hole as it spreads upwards from the bottom of the injection hole. This air is then discharged through the arc-shaped air groove 15. This process avoids the situation where some gas remains in the mortar when the mortar is injected from the top, which could lead to voids in the cured mortar. At the same time, the presence of a sealing plate 13 and a rubber ring 14 at the outlet of the injection hole can seal the outlet, preventing rainwater from flowing into the injection hole during later use. This would soften the hole wall and affect the fixing effect of the fixing components.

[0022] As one embodiment of the present invention; the outer ring of the insert 1 is provided with uniformly arranged vertical grooves 3, and the vertical grooves 3 and the sliding grooves 12 are staggered; Each of the vertical grooves 3 has a rotating plate 31 that rotates through a rotating shaft, and the top of the rotating plate 31 is conical and fits against the two sides of the vertical groove 3; A trapezoidal block 32 is fixed on the side of the rotating plate 31 facing the injection tube 2, and the side of the trapezoidal block 32 facing the injection tube 2 is arc-shaped. In this embodiment, the rotating plate 31 includes a sliding plate 311 and a sliding cylinder 312, and the sliding plate 311 slides within the sliding cylinder 312 by means of a spring; The slide cylinder 312 rotates within the vertical groove 3 via a rotating shaft; the trapezoidal block 32 is fixed on the slide plate 311; The top of the slide plate 311 is provided with a notch 33 inside the insert 1, and the notch 33 is connected to the outside of the insert 1; the top of the notch 33 is an arc surface; The sliding plate 311 extends into the notch 33 under the thrust of the spring and abuts against the arc surface of the notch 33. The spring is compressed under the obstruction of the rotating plate 31. At the same time, the rotating plate 31 is limited within the arc surface of the notch 33 by the limiting of the arc surface of the notch 33, and the rotating plate 31 is prevented from rotating into the insert 1. In this embodiment, the slide cylinder 312 is U-shaped; the width of the slide cylinder 312 is the same as the width of the rotating plate 31, and both fit against the two sides of the vertical groove 3. The cavity inside the slide cylinder 312 extends through both sides of the slide cylinder 312; In this embodiment, a conical block 34 is fixed on the side surface of the rotating plate 31 away from the injection tube 2; During implementation, as the mortar pushes the push ring 22 upward, when the push ring 22 passes the rotating plate 31, it will contact the trapezoidal block 32 and push the trapezoidal block 32 to rotate. During the rotation of the trapezoidal block 32, it will gradually rotate into the grouting hole and into the mortar inside the grouting hole, thus acting as aggregate inside the mortar. When the push ring 22 passes through the vertical groove 3, the mortar inside the insert 1 will communicate with the mortar inside the grouting hole. The mortar inside the insert 1 can enter the grouting hole through the vertical groove 3, thereby further filling the mortar inside the grouting hole. At the same time, after the mortar solidifies, it can make the mortar inside the grouting hole and the insert 1 form a whole, thereby improving the fixing effect of the fixing component. Specifically, because the slide plate 311 is pressed against the arc surface of the notch 33 by the spring, the rotating plate 31 is prevented from rotating out of the vertical groove 3. Because the notch 33 can block the rotating plate 31, it can prevent the rotating plate 31 from rotating into the insert 1. When the push ring 22 passes the arc block, it will push the rotating plate 31 to rotate in the arc surface of the notch 33. Because the rotating plate 31 is blocked by the arc surface of the notch 33, the slide plate 311 will first slide downward into the slide cylinder 312. After the slide plate 311 passes the arc surface of the notch 33, it will return to its original shape under the action of the spring and rotate into the mortar. More specifically, since the slide cylinder 312 is U-shaped, when the slide cylinder 312 rotates with the slide plate 311, the U-shaped slide cylinder 312 will rotate into the grouting hole, and the slide cylinder 312 will no longer be obstructed by the vertical groove 3. At this time, the mortar will enter the slide cylinder 312 and flow into the slide plate 311 and the spring below. After the mortar solidifies, it can fix the slide plate 311 and the slide cylinder 312. At the same time, when the slide plate 311 rotates, it can drive the conical block 34 to rotate. The rotating conical block 34 can abut against the side wall of the grouting hole, thereby improving the fixing effect of the fixing component inside the grouting hole. In this process, by using the sliding plate 311 and the sliding cylinder 312 inside the injection hole as aggregate inside the mortar, the insert 1 can be fixed as a whole by the sliding plate 311 and the sliding cylinder 312, further enhancing the stability of the overall mortar structure. When the rotating plate 31 rotates, the mortar in the insert 1 that has not been fully cured can flow into the injection hole through the vertical groove 3, filling any small gaps that may exist in the injection hole and further filling the mortar in the injection hole. At the same time, during the rotation of the rotating plate 31, the conical block 34 can be driven to abut against the side wall of the injection hole. When the mortar enters the sliding cylinder 312 and cures, it will firmly lock the position of the rotating plate 31 and the conical block 34, so that the conical block 34 always maintains the abutment force against the side wall of the injection hole, avoiding the problem that traditional anchors rely solely on the bonding force of mortar and are prone to a decrease in pull-out resistance due to mortar aging.

[0023] As one embodiment of the present invention; a T-shaped rod 4 is fixedly installed on the top of the insert 1; An inverted L-shaped rod 41 slides on the T-shaped rod 4, and part of the inverted L-shaped rod 41 extends into the insert 1; a spring is provided above the inverted L-shaped rod 41, and the spring is sleeved on the T-shaped rod 4; In this embodiment, a threaded rod 42 is fixed to the bottom of the T-shaped rod 4; The top of the insert 1 is provided with a threaded groove, and the threaded rod 42 is threadedly engaged in the threaded groove; During implementation, when the push ring 22 moves up to the top position of the insert 1, the push ring 22 will gradually come into contact with the inverted L-shaped rod 41. After the push ring 22 comes into contact with the inverted L-shaped rod 41, the push ring 22 will push the inverted L-shaped rod 41 upward, compress the spring, and then close the valve 21 to stop the injection of mortar. At this time, the push ring 22 is squeezed by the inverted L-shaped rod 41 and the spring, so that the push ring 22 squeezes the mortar below. During the process of the push ring 22 squeezing the mortar, the push ring 22 can continuously squeeze the mortar inside the insert 1 and the grouting hole below. The squeezing force will be transmitted to the grouting hole through the mortar inside the insert 1, pushing the mortar to further penetrate into the fine cracks in the hole wall of the grouting hole, filling the local dead corners that may have been left by the previous bottom grouting, so as to improve the mortar density of the entire grouting area and avoid the local looseness of the mortar inside the grouting hole, which would lead to a reduction in anchoring force. After the mortar has cured, the T-shaped rod 4 engages with the threaded groove at the top of the insert 1 through the threaded rod 42. Therefore, the T-shaped rod 4 can be rotated to remove the threaded rod 42 from the threaded groove, thereby removing the T-shaped rod 4 and the inverted L-shaped rod 41.

[0024] As one embodiment of the present invention; the rubber ring 14 is made of a water-absorbing and swellable rubber material; A rubber layer 141 is fixed to the inner surface of the rubber ring 14, and the rubber layer 141 is made of ordinary elastic rubber material; the cross-section of the rubber layer 141 is L-shaped and fits against the inner ring and bottom part of the rubber ring 14. During implementation, when it rains, rainwater passes through the rubber ring 14. Since the rubber ring 14 is made of water-absorbing and expanding rubber material, it will expand after absorbing water, which will squeeze the rubber layer 141 and cause the rubber layer 141 to expand itself. The expanded rubber layer 141 will squeeze the slope around the injection hole, thereby improving the sealing effect with the injection hole and preventing rainwater from entering the injection hole, which would soften the hole wall and affect the fixing effect of the fixing component.
