Description

Technical Field

[0001] The invention relates to the field of slope reconstruction, in particular to a slope reinforcement structure based on reconstruction of existing slope landslides. Background Art

[0002] With the acceleration of urbanization and the continuous development of infrastructure construction, the application of slope engineering is increasing, especially in roads, railways and other engineering projects in mountainous and hilly areas. However, due to the complex geological conditions, slopes often slide or collapse, which seriously threatens the safety of engineering, the safety of life and property of personnel and the stability of the surrounding environment. Therefore, slope reinforcement technology is particularly important as a key measure to prevent and control slope collapse and landslides.

[0003] There are many kinds of slope reinforcement technology methods, the most common ones are anchoring method, support method, shotcrete method, reinforcement grouting method, etc. Among them, the anchoring method is widely used in slope reinforcement projects because of its high stability and low construction cost. However, traditional reinforcement technology usually has the following problems:

[0004] Poor adaptability: Most existing slope reinforcement structures are difficult to adapt to different slope curvatures, especially for irregular slopes or slopes with severe collapse, the reinforcement effect is not ideal.

[0005] High construction complexity: In traditional slope reinforcement technology, the construction steps are complicated, the structure needs to be adjusted many times, and the position of the reinforcement needs to be precisely controlled, which makes construction difficult.

[0006] Insufficient stability: Some traditional slope reinforcement structures may be insufficiently reinforced or have loose anchors when subjected to large external forces or long-term loads, affecting the long-term stability of the slope.

[0007] Therefore, in view of the problems existing in traditional slope reinforcement, the existing technology proposes the following solutions:

[0008] 1) Publication No. CN114855834A discloses a geotechnical engineering slope reinforcement device and its use method. In this technical application, it includes a tower connecting rod, which is placed in a groove. A plurality of spanning rods are hinged on the top of the tower connecting rod, and the plurality of spanning rods are arranged at equal distances. The geotechnical engineering slope reinforcement device forms a frame through spanning rods, spanning rods and snap-on components. The frame is pressed on the slope. A groove is opened on the slope. The spanning rods are embedded in the grooves, so that the frame presses tightly against the slope surface to achieve a shaping effect. Green planting troughs are set up to reduce soil erosion and the probability of landslides caused by soil erosion by planting green plants. U-shaped conductive plates, thin ropes and conductive balls are used to detect the condition of the slope. When the slope landslide is serious, the motor is started to pull the elastic bag cloth upwards, thereby preventing rocks and soil blocks from continuing to slide down.

[0009] 2) Publication No. CN111236267A discloses a foundation pit slope support structure. In this technical application, it includes a cover plate arranged on the outer side slope of the foundation pit, the end of the cover plate away from the foundation pit is fixedly connected to an outer baffle plate inserted into the soil layer of the foundation pit slope, the other end of the cover plate is connected to an inner guard plate attached to the inner wall of the foundation pit, a fixing piece is fixedly connected between the inner guard plate and the inner wall of the foundation pit, a water guide groove is opened on the cover plate on the side of the inner guard plate away from the foundation pit, the water guide groove is connected to an underground water channel, and a pumping assembly connecting the foundation pit and the water guide groove is arranged in the foundation pit. By adopting the above scheme, the cover plate is pressed on the surface of the foundation pit slope under the fixing action of the inner guard plate inserted into the soil layer at both ends and the outer baffle plate, so as to effectively prevent the slope soil layer from slipping, and at the same time, it can be shielded in rainy weather to prevent the soil layer from being overly soaked and collapsed.

[0010] 3) Publication No. CN115573356A discloses a grid-type reinforcement method and device for treating weak slopes of foundation pits. In this technical application, the reinforcement method includes pouring anti-sliding piles, installing anchor cables, and pouring concrete layers on the slopes. The device includes a device body, which includes a fixture assembly, which includes a first connecting mechanism and a second connecting mechanism. The first connecting mechanism includes a first internal thread, a first connecting ring, a first limiting groove, a first rotating ring, and a first external thread, and the second connecting mechanism includes a second internal thread, a second connecting ring, a second limiting groove, a second rotating ring, and a second external thread. It can achieve the function of strengthening the structural strength of the concrete layer at the slope and preventing the concrete layer from being pushed away from the slope by the thrust of the slope, thereby achieving the effect of preventing the slope from sliding and reinforcing the slope.

[0011] 4) Publication No. CN116378054A discloses a deep foundation pit reinforcement device and a reinforcement construction method thereof. In this technical application, it includes several rows of jet grouting piles, which are arranged one by one on several levels of foundation pit slopes excavated in stages. Each row of the jet grouting piles includes several jet grouting piles, and each level of the foundation pit slope is cast with a ground beam through concrete. The tops of the jet grouting piles in the same row are buried in the concrete of the ground beam, and each level of the foundation pit slope is buried with several groups of anchor cables, and one end of each group of anchor cables exposed from the foundation pit slope is buried in the concrete of the ground beam. This application has the effect of improving the integrity between the jet grouting piles of the same level of foundation pit.

[0012] In the above-mentioned prior art, although a variety of slope reinforcement methods have been proposed, there are still some shortcomings, especially in terms of adaptability, construction complexity and stability. The specific analysis is as follows:

[0013] Poor adaptability:

[0014] The geotechnical engineering slope reinforcement device proposed in CN114855834A can form a frame on the slope and use green plants to reduce soil erosion, but the structure of the device is relatively fixed and does not take into account the changes in the different curvatures and slopes of the slope. In particular, for irregular or severely deformed collapsed slopes, the frame has insufficient adaptability and may not be able to provide uniform and effective support at different parts of the slope.

[0015] The foundation pit slope support structure in CN111236267A prevents slope sliding by cooperating between a cover plate and a guard plate. However, this structure is difficult to effectively adapt to different slopes when the curvature of the slope changes greatly, and the support structure cannot be flexibly adjusted to cope with changes in the slope shape.

[0016] High construction complexity:

[0017] Although the grid reinforcement method proposed in CN115573356A can effectively increase the stability of the slope, the construction process is relatively complicated, requiring the pouring of anti-slide piles first, the installation of anchor cables, and finally the pouring of concrete. This series of steps is not only cumbersome, but also requires high accuracy and technical requirements for construction, increasing the difficulty and cost of construction;

[0018] The jet grouting pile reinforcement technology mentioned in CN116378054A has advantages in improving integrity, but has a long construction period and involves multiple steps, including the setting of jet grouting piles, the pouring of ground beams, and the installation of anchor cables. A large amount of manual operation and mechanical equipment support are required during the construction process, so the construction efficiency and cost are relatively high.

[0019] Lack of stability:

[0020] Although the geotechnical engineering slope reinforcement device in CN114855834A forms a frame by overlapping rods and snap-fit ​​components, this structure only relies on the frame to press the slope, and does not involve anchoring technology that penetrates deep into the bottom of the slope. This may result in the overall stability being less than ideal under the action of large external forces or long-term loads, especially in the face of more complex or extreme geological conditions, and there may be a risk of loosening or instability of the frame;

[0021] The support structure in CN111236267A achieves support by plugging in baffles. Although it can prevent soil slippage, it does not take into account the problem of deep stability at the bottom of the slope. Especially in areas with severe landslides, the fixing method of the outer baffle and the inner guard plate may not be sufficient to withstand large lateral forces, thus limiting the reinforcement effect.

[0022] Poor structural flexibility:

[0023] Most of the existing technologies, such as CN115573356A and CN116378054A, use fixed reinforcement structures, which cannot be flexibly adjusted according to the actual changes of the slope. Such structures are too rigid, and when facing irregular slopes or changes in slope, it is difficult to make effective adjustments as needed, resulting in unstable reinforcement effects. Summary of the invention

[0024] The purpose of the present invention is to provide a slope reinforcement structure based on the transformation of existing slope landslides, which can effectively overcome the problems of poor adaptability, complex construction, insufficient stability, etc. in the prior art, and provide an efficient, flexible and stable slope reinforcement solution.

The adjusting screw thread passes through the upper bracket and is connected to the support.

[0028] Preferably, the entire reinforcement structure is composed of a reinforcement frame member and an anchoring member. The reinforcement structure provides stable support for the collapsed slope. The reinforcement structure can adjust the lateral frame using a damping adjustment rod according to the curvature of the slope, so that the angle between the lateral frame and the transverse frame changes, thereby adapting to slopes of different curvatures. In addition, the anchoring members arranged on the reinforcement frame members can be installed in an offset manner along the reinforcement frame members, and the anchoring members can penetrate into the bottom side of the slope to stabilize the slope within the reinforcement frame member area, thereby further improving the stability of the entire reinforcement structure.

[0029] Preferably, the lateral frame is hingedly mounted at the rear end of the transverse frame, and a damping adjustment rod connected to the lateral frame and enabling the lateral frame to deflect relative to the transverse frame is installed on the transverse frame. The transverse frame and the lateral frame are arranged along the top to the toe of the collapsed slope, and the bottom of the legs of the transverse frame and the lateral frame are provided with reinforcement nails extending into the top and the inner side of the toe of the slope respectively. The bottom sides of the transverse frame and the lateral frame are fixed to the top, the slope and the toe of the slope by the reinforcement nails, and the angle between the lateral frame and the transverse frame can be adjusted by the damping adjustment rod.

[0030] Preferably, an anchoring unit is installed on the lower side of the support, and the anchoring unit includes a base plate, a handle, a disc, a rotating rod, a V-shaped rod, a first swing arm, a second swing arm, a first anchor mounting frame, a second anchor mounting frame and an anchor rod, wherein a long opening is opened on the end surface of the base plate, and the first anchor mounting frame and the second anchor mounting frame have the same structure and their bottom ends are respectively hinged on both sides of the end surface of the base plate.

[0031] Preferably, the disc is rotatably mounted on the bottom plate, a handle is provided on one side of the disc to drive it to rotate, a rotating rod is hinged on the eccentric side of the end face of the disc, and a V-shaped rod and a first swing rod are coaxially hinged on the end of the rotating rod.

[0034] Preferably, the anchor rod is inserted into the inner side of the opening of the anchor sleeve, and the bottom end of the anchor rod passes through the anchor sleeve and penetrates into the bedrock layer or weathered rock layer of the slope.

[0035] Preferably, the above-mentioned anchoring component is composed of an upper bracket, an adjusting screw, a support and an anchoring unit.

At this time, the first anchor mounting frame and the second anchor mounting frame both move synchronously, and the overall volume of the first anchor mounting frame and the second anchor mounting frame is small when they are stored. The main purpose of the first anchor mounting frame and the second anchor mounting frame is to unfold the anchoring sleeves thereon, so that when the anchor rod is installed, it only needs to be passed through the anchoring sleeve, and it can be mechanically The pressing method or drilling and grouting method allows the anchor rods to penetrate into the bedrock layer or weathered rock layer of the slope. The main functions of the anchoring components are divided into the following two types: one is to assist in reinforcing the frame components, which can extend into the bottom layer of the slope to keep the slope stable; the second is to reduce the operating steps during anchoring, that is, the first anchor mounting frame and the second anchor mounting frame are in a swinging and unfolding state, and each anchor mounting frame is equipped with a number of anchor sleeves and anchor rods. The position of the anchor sleeves on the anchor mounting frame is adjustable. During anchoring construction, it is only necessary to adjust the anchor mounting frame so that the multiple anchor mounting frames on the transverse frame and the lateral frame are in an interlaced state. At this time, the anchor rods on the anchor mounting frame can be quickly installed through mechanical pressing or drilling and grouting.

[0036] Preferably, the present invention also provides a construction method for the above-mentioned slope collapse, which provides stable support and adapts to different slope curvatures by designing a combination of reinforcement frame members and anchoring members to ensure that the slope remains stable after reinforcement. The construction steps include the following:

[0037] 1) Preparation:

[0038] Clean up the collapsed slope: First, clean up the excess loose soil, gravel and obstacles on the slope to ensure that the construction area is clean and flat;

[0039] Determine the top and toe of the slope: Based on the on-site survey, determine the top and toe of the collapsed slope to ensure the correct layout of the reinforcement structure;

[0040] Choose appropriate reinforcement frame components: According to the specific conditions and curvature of the slope, choose appropriate transverse frames and lateral frames to meet the needs of different slopes;

[0041] Adjust the angle: During the installation process, use the damping adjustment rod to adjust the angle between the transverse frame and the lateral frame to adapt it to the slope changes and ensure the stability of the structure.

[0042] 2) Install reinforcement components:

[0043] Install the transverse frame and the lateral frame: install the transverse frame and the lateral frame along the slope from the top to the toe. The top of the transverse frame and the lateral frame is provided with a slide groove for sliding the adjustment bracket, and the bottom is provided with a support foot, which is fixed on the top, the slope and the toe of the slope by reinforcing nails;

[0044] Adjust the structure position: Make sure the reinforcement nails at the bottom of the legs extend into the inside of the top and toe of the slope to provide stable support;

[0045] Adjust the structural angle: adjust the angle between the transverse frame and the lateral frame through the damping adjustment rod to adapt to the curvature of the slope and ensure the stability of the reinforced frame components.

[0046] 3) Install anchoring components:

[0047] Adjust the anchoring member: before installing the anchoring member, first turn the adjusting screw to make the support go down and approach the slope surface. This step ensures that the anchoring member can accurately dock with the slope surface; use the handle to drive the disc to rotate, thereby driving the V-shaped rod, the first swing rod and the second swing rod to move, so that the first anchor mounting frame and the second anchor mounting frame are in an unfolded state;

[0048] Arrange the anchoring unit: on the first and second anchoring member mounting frames of the anchoring member, by adjusting the long slot and the anchoring sleeve, the anchor rod can smoothly pass through the sleeve and penetrate into the slope surface;

[0049] Anchor installation: Anchors are installed by mechanical pressing or drilling grouting. After the anchor is inserted into the anchor sleeve, the bottom end of the anchor goes deep into the bedrock or weathered rock layer at the bottom of the slope.

[0050] 4) Ensure the stability of the reinforced structure:

[0051] Check the distribution of anchors: ensure that the spacing and position of each group of anchor components are reasonable, avoid interference between anchor components, and ensure the overall reinforcement effect;

[0052] Adjust the structural position: According to the changes in the slope during the construction process, flexibly adjust the angle between the transverse frame and the lateral frame to adapt to the changes in different slopes and ensure the continued stability of the reinforced frame components.

[0053] 5) Complete reinforcement construction:

[0054] Fix all anchor components: Make sure all anchors and reinforcement nails are firmly fixed and penetrate deep into the bottom layer of the slope. The installation of anchor components can effectively enhance the stability of the entire structure and provide strong support for the slope;

[0055] Inspection and acceptance: Check the construction quality to ensure that the reinforced structure is not loose or unstable. After accepting the construction quality, complete the slope reinforcement.

[0056] Compared with the prior art, the present invention has the following beneficial effects:

[0057] Strong adaptability: The present invention is designed with an adjustable damping adjustment rod, which can flexibly adjust the angle between the transverse frame and the lateral frame according to the curvature of the different slopes, so as to adapt to irregular or severely deformed slopes and provide more precise support. This design can better adapt to changes in different slopes and ensure the stability of the slope reinforcement effect; and the present invention simplifies the construction process. By configuring an adjustable structure and easy-to-install anchoring components, the complexity of the construction steps is greatly reduced. The anchoring components can be installed by mechanical pressing or drilling and grouting, which reduces the difficulty of manual operation and improves construction efficiency.

[0058] Strong stability: The present invention can penetrate into the bottom side of the slope to effectively stabilize and provide strong support through the reinforcement frame components and the staggered anchor components; and through the staggered installation, the anchor components can provide more comprehensive support at the bottom of the slope, avoiding the loosening or instability caused by the fixed bracket in the traditional technology. Since the anchor components are designed with multiple groups of staggered installation structures, each group of anchor components includes an adjustment screw, a support and an anchor unit. The staggered distribution of anchor components can distribute the reinforcement force more evenly, avoiding the structural damage caused by concentrated pressure, thereby effectively improving the stability of the anchoring effect. This design can ensure that the reinforced structure maintains a stable state for a long time, avoid the problems of loosening and falling of the anchor, and ensure the long-term stability of the slope. The adjustment screw and support equipped with the anchor component can adjust the position of the anchor so that the anchor can accurately dock with the slope, ensuring that each anchor can effectively fix the slope in the best position. This precise adjustment design can avoid the problem of anchor failure caused by inaccurate positioning in the traditional method, and improve the reliability of the entire reinforcement system. In addition, the design of the anchoring components can effectively prevent misoperation or deviation during the anchoring process. Through precise adjustment and fixing devices, the problem of improper anchoring position or anchoring depth during construction is avoided, thereby reducing the risks during construction and ensuring the safety of construction workers. At the same time, the reliability of the reinforcement effect further improves the safety of the construction area and reduces the risk of slope collapse.

[0059] Improve the overall benefits of the project: The anchoring components of the present invention are efficient, accurate and reliable in construction, which shortens the construction period of the entire slope reinforcement project and significantly improves the construction quality and effect. This not only greatly reduces the construction cost, but also improves the overall benefits of the project. Especially in large-scale slope projects, the use of the anchoring components of the present invention can significantly reduce the total cost of the project and improve the economic benefits of the project.

[0071] See also Figure 1-Figure 2In this embodiment, the reinforcement frame member 1 includes a transverse frame 101, a lateral frame 102, a damping adjustment rod 103 and a support 203.

[0073] See also Figure 1-Figure 4 In this embodiment, a plurality of anchoring members 2 are provided and are distributed along the transverse frame 101 and the lateral frame 102. The plurality of transverse frames 101 and the lateral frames 102 are distributed at staggered intervals. Each group of anchoring members 2 includes an upper bracket 201, an adjusting screw 202, a support 203 and an anchoring unit. The upper bracket 201 is slidably mounted in a slide groove on the top side of the transverse frame 101 and the lateral frame 102. An adjusting screw 202 is arranged on the upper bracket 201. The adjusting screw 202 is threadedly penetrated through the upper bracket 201 and connected to the support 203.

[0074] In this embodiment, an anchoring unit is installed on the lower side of the support 203, and the anchoring unit includes a base plate 204, a handle, a disc 205, a rotating rod 206, a V-shaped rod 207, a first swing rod 208, a second swing rod 209, a first anchor mounting frame 210, a second anchor mounting frame 211 and an anchor rod 213, wherein a long opening is opened on the end surface of the base plate 204, the first anchor mounting frame 210 and the second anchor mounting frame 211 have the same structure and their bottom ends are respectively hinged on both sides of the end surface of the base plate 204; the disc 205 is rotatably installed on the base plate 204, and the disc 205 is rotated. A handle is provided on the side for driving it to rotate, a rotating rod 206 is hinged on the eccentric side of the end face of the disk 205, and a V-shaped rod 207 and a first swing rod 208 are coaxially hinged on the end of the rotating rod 206; the upper end of the first swing rod 208 is hinged to the first anchor mounting frame 210, the middle of the V-shaped rod 207 is movably connected to the bottom side of the base plate 204, the upper end of the V-shaped rod 207 is hinged to the second swing rod 209, and the free end of the second swing rod 209 is movably connected to the second anchor mounting frame 211, the first anchor mounting frame 210 and the second anchor mounting frame 211 rotate and swing with the disk 205.

[0075] In this embodiment, the first anchor mounting frame 210 and the second anchor mounting frame 211 both include a frame body, an adjustment slot provided on the frame body, and an anchor sleeve 212 slidably connected to the adjustment slot, and an opening is provided in the middle of the anchor sleeve 212.

[0076] In this embodiment, the anchor rod 213 is inserted into the inner side of the opening of the anchor sleeve 212, and the bottom end of the anchor rod 213 passes through the anchor sleeve 212 and penetrates into the bedrock layer or weathered rock layer of the slope.

[0077] In this embodiment, the entire reinforcement structure is composed of a reinforcement frame member 1 and an anchor member 2. The reinforcement structure provides stable support for the collapsed slope. The reinforcement structure can adjust the lateral frame 102 using the damping adjustment rod 103 according to the curvature of the slope, so that the angle between the lateral frame 102 and the transverse frame 101 changes, so as to adapt to slopes of different curvatures. In addition, the anchor member 2 configured on the reinforcement frame member 1 can be installed in an offset manner along the reinforcement frame member 1, and the anchor member 2 can penetrate into the bottom side of the slope to stabilize the slope in the area of ​​the reinforcement frame member 1, thereby further improving the stability of the entire reinforcement structure.

[0078] The design of the anchoring member 2 takes into account the adaptability to different slopes and geological conditions. By adjusting the installation position and depth of the anchor, the anchoring member 2 can penetrate deep into the bedrock or weathered rock layer, not only providing strong support, but also effectively avoiding the unsatisfactory reinforcement effect caused by complex geological conditions in traditional reinforcement methods. Whether it is soft soil or hard rock, the anchoring member 2 can accurately apply anchoring force to ensure the reinforcement effect.

[0079] In this embodiment, the anchoring member 2 adopts a mechanical pressing method or a drilling and grouting method to install the anchor rod, which reduces the cumbersome manual operation steps in the traditional anchoring technology. Through the adjustment slot and the sliding anchoring sleeve 212 on the anchoring member 2, the construction personnel can easily adjust the position of the anchor so that the anchor rod 213 can quickly and accurately enter the bedrock or weathered rock layer. This installation method greatly simplifies the anchoring construction process and reduces the construction difficulty and time. Moreover, the anchoring member 2 is designed as a plurality of independent but staggered units, which can effectively disperse the external force applied to the reinforced structure. Each group of anchoring members 2 acts independently, but forms an overall reinforcement effect through staggered distribution, ensuring the efficiency and stability of the overall reinforcement system. The design of staggered distribution can avoid the concentrated pressure in a certain area, reducing the risk of overall collapse of the slope due to failure of local reinforcement.

[0080] In the present embodiment, the anchoring member 2 is composed of an upper bracket 201, an adjusting screw 202, a support 203 and an anchoring unit. The adjusting screw 202 can be rotated to make the support 203 move downward to approach the slope, and then the handle is used to drive the disc 205 to rotate, so that the disc 205 drives the V-shaped rod 207 and the first swing rod 208 to move. The first swing rod 208 is linked to the first anchor mounting frame 210, and the V-shaped rod 207 drives the second anchor mounting frame 211 through the second swing rod 209. At this time, the first anchor mounting frame 210 and the second anchor mounting frame 211 are both synchronously moved. The overall volume of the first anchor mounting frame 210 and the second anchor mounting frame 211 is small when they are stored. The main purpose of the first anchor mounting frame 210 and the second anchor mounting frame 211 is to unfold the anchor sleeve 212 thereon, so that the anchor rod 213 only needs to be installed. The anchor rod 213 needs to be inserted into the anchor sleeve 212, and the anchor rod 213 can be penetrated into the bedrock layer or weathered rock layer of the slope by mechanical pressing or drilling grouting. The main functions of the anchor component 2 are divided into the following two types: one is to assist the reinforcement frame component 1, which can extend into the bottom layer of the slope to keep the slope stable; the other is to reduce the operation steps during anchoring, that is, the first anchor mounting frame 210 and the second anchor mounting frame 211 are in a swinging and unfolding state, and each anchor mounting frame is equipped with a plurality of anchor sleeves 212 and anchor rods 213. The position of the anchor sleeve 212 on the anchor mounting frame is adjustable. During anchoring construction, it is only necessary to adjust the anchor mounting frame so that the multiple anchor mounting frames on the transverse frame 101 and the lateral frame 102 are in an alternate state. At this time, the anchor rods 213 on the anchor mounting frame can be quickly installed by mechanical pressing or drilling grouting.

[0081] This embodiment also provides a construction method for the above-mentioned slope collapse, by designing a combination of a reinforcement frame member 1 and an anchor member 2 to provide stable support and adapt to different slope curvatures, ensuring that the slope remains stable after reinforcement. The construction steps include the following:

[0082] 1) Preparation:

[0083] Clean up the collapsed slope: First, clean up the excess loose soil, gravel and obstacles on the slope to ensure that the construction area is clean and flat;

[0084] Determine the top and toe of the slope: Based on the on-site survey, determine the top and toe of the collapsed slope to ensure the correct layout of the reinforcement structure;

[0085] Select appropriate reinforcement frame member 1: Select appropriate transverse frame 101 and lateral frame 102 according to the specific conditions and curvature of the slope to meet the needs of different slopes;

[0086] Adjusting the angle: During the installation process, the damping adjustment rod 103 is used to adjust the angle between the transverse frame 101 and the lateral frame 102 to adapt to the slope change and ensure the stability of the structure.

[0087] 2) Install reinforcement frame component 1:

[0088] Install the transverse frame 101 and the lateral frame 102: install the transverse frame 101 and the lateral frame 102 along the slope from the top to the toe of the slope. The top of the transverse frame 101 and the lateral frame 102 is provided with a slide groove for sliding the adjustment bracket, and the bottom is provided with a support foot, and is fixed on the top, the slope and the toe of the slope by reinforcing nails 104;

[0089] Adjust the structure position: ensure that the reinforcement nails 104 at the bottom of the support leg extend into the inside of the top and toe of the slope to provide stable support;

[0090] Adjusting the structural angle: adjusting the angle between the transverse frame 101 and the lateral frame 102 through the damping adjustment rod 103 to adapt to the curvature of the slope and ensure the stability of the reinforcement frame member 1.

[0091] 3) Install anchoring member 2:

[0092] Adjust the anchor member 2: before installing the anchor member 2, first rotate the adjusting screw 202 to make the support 203 move downward and approach the slope surface. This step ensures that the anchor member 2 can accurately dock with the slope surface; use the handle to drive the disc 205 to rotate, thereby driving the V-shaped rod 207, the first swing rod 208 and the second swing rod 209 to move, so that the first anchor mounting frame 210 and the second anchor mounting frame 211 are in an unfolded state;

[0093] Arrange the anchoring unit: on the first and second anchoring member mounting frames 211 of the anchoring member 2, by adjusting the long slot and the anchoring sleeve 212, the anchor rod 213 can smoothly pass through the sleeve and penetrate into the slope surface;

[0094] Installation of anchor rod 213: Anchor rod 213 is installed by mechanical pressing method or drilling grouting method. After anchor rod 213 is inserted into anchoring sleeve 212, the bottom end of anchor rod 213 penetrates into the bedrock or weathered rock layer at the bottom side of the slope.

[0095] 4) Ensure the stability of the reinforced structure:

[0096] Check the distribution of anchors: ensure that the spacing and position of each group of anchoring members 2 are reasonable, avoid interference between the anchoring members 2, and ensure the overall reinforcement effect;

[0097] Adjust the structural position: According to the change of the slope during the construction process, the angle between the transverse frame 101 and the lateral frame 102 is flexibly adjusted to adapt to the change of different slopes to ensure the continuous stability of the reinforcement frame member 1.

[0098] 5) Complete reinforcement construction:

[0099] Fix all anchoring members 2: Confirm that all anchors and reinforcing nails 104 are firmly fixed and penetrate into the bottom layer of the slope. The installation of anchoring members 2 can effectively enhance the stability of the entire structure and provide strong support for the slope;

[0100] Inspection and acceptance: Check the construction quality to ensure that the reinforced structure is not loose or unstable. After accepting the construction quality, complete the slope reinforcement.

[0101] Note:

[0102] During the construction process, it is necessary to ensure that the spacing and position of each group of anchoring members 2 are adjusted reasonably to ensure the overall reinforcement effect.

[0103] During construction, the angle between the lateral frame 102 and the transverse frame 101 should be flexibly adjusted according to the actual situation of the slope to adapt to changes in different slopes.

[0104] Through the above steps, the slope can be effectively stabilized, the risk of collapse can be reduced, and the safety and long-term stability of the construction area can be ensured.
