Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering technology, and in particular to a geotechnical engineering slope reinforcement framework structure and reinforcement method. Background Technology

[0002] Geotechnical engineering is a branch of civil engineering that applies engineering geology, soil mechanics, and rock mechanics to solve engineering problems related to rocks and soil in various engineering projects. According to the stages of engineering construction, the work content can be divided into: geotechnical engineering investigation, geotechnical engineering design, geotechnical engineering remediation, geotechnical engineering monitoring, and geotechnical engineering testing. The main research directions are: urban underground space and underground engineering, slope and foundation engineering, and foundation engineering. Among these, slope and foundation engineering focuses on the impact of foundation pit excavation (including dewatering) on ​​adjacent existing buildings and the environment, the design and calculation theories and methods of foundation pit support structures, the optimization design and reliability analysis techniques of foundation pit support structures, slope stability analysis theories, and the development and application of new support technologies.

[0003] Earthen road cut slopes are prevalent in road cut engineering. When constructing excavated earthen slopes, the effects of rainfall and slope toe stress must be considered; therefore, reinforcement measures are usually required. When the earthen road cut is very high, a common approach is to install reinforcing piles at the slope toe and construct a retaining frame on the slope surface. When the earthen road cut slope is relatively high, a retaining wall is typically constructed at the slope toe, and a retaining frame is used on the slope surface. For lower slopes, a retaining frame is used directly.

[0004] Currently, most existing slope protection systems utilize cast-in-place concrete frameworks. However, the cast-in-place process demands a large and concentrated workforce, and the construction cycle is lengthy due to the coordination of various processes and inspection procedures. Therefore, the construction of cast-in-place concrete framework slope protection systems is often affected by factors such as process flow, number of personnel, and number of formwork, resulting in a long construction period and disadvantages such as fluctuating quality of cast-in-place concrete and high labor demand. Furthermore, the cast-in-place concrete framework generally forms an interconnected monolithic structure; damage or breakage in any part of this structure will affect the overall framework and thus the overall strength of the slope protection, posing certain safety hazards. Subsequent maintenance is also inconvenient, and repairing the broken areas with secondary cast-in-place concrete will consume a significant amount of time. Additionally, cast-in-place concrete framework slope protection systems are also subject to settlement or landslide risks during rainy weather. To address these issues, it is necessary to design a geotechnical engineering slope reinforcement framework structure and reinforcement method. Summary of the Invention

[0005] The purpose of this invention is to provide a geotechnical engineering slope reinforcement framework structure and reinforcement method to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A buffer trough is set on the ground adjacent to the slope above the slope;

[0009] The positioning tube has one end vertically inserted into the ground above the slope and the other end extending upward to the bottom of the buffer trough. The positioning tubes are arranged in multiple sets at intervals along the extension direction of the buffer trough. The lower end of the positioning tube inserted into the ground is provided with a first anchor head to prevent the positioning tube from moving upward and detaching from the ground.

[0010] The prefabricated frame consists of multiple sets laid on the slope, which are longitudinally connected end to end and laterally connected to form a grid shape on the slope.

[0028] And a second opening, which is located on the side of the second cone.

[0029] Furthermore, the splicing and fixing mechanism includes:

[0030] A strip-shaped protrusion is horizontally positioned at the end of the precast frame in the longitudinal direction. A through half-hole groove is formed on the strip-shaped protrusion at the edge of the end of the precast frame in the longitudinal direction. After the two precast frames are joined end to end in the longitudinal direction, the two corresponding strip-shaped protrusions are joined together to form a hole through which the anchor rod passes.

[0031] And an arc-shaped cover plate, which is an arc-shaped plate structure and is fastened on the two strip-shaped protrusions that have been connected. The arc-shaped cover plate has a hole through which the anchor rod passes and corresponds to the hole formed by the two half-hole grooves. The anchor rod passing through the hole in the arc-shaped cover plate is tightened and fixed to the arc-shaped cover plate by a nut.

[0032] Furthermore, the splicing rope is connected between two longitudinally adjacent anchor rods on two adjacent prefabricated frames that are joined end to end in the longitudinal direction, and the splicing rope is also connected between two laterally adjacent anchor rods on two adjacent prefabricated frames that are arranged opposite each other in the transverse direction.

[0033] A slope reinforcement method based on a geotechnical engineering slope reinforcement framework structure includes the following steps:

[0034] Step 1: Drive a positioning tube with the first anchor head into the ground adjacent to the slope above the slope;

[0035] Step 2: Pour a water-retaining buffer trough on the ground adjacent to the slope above and make the upper end of the positioning pipe extend from the bottom of the buffer trough;

[0036] Step 3: Drive horizontal drainage pipes into the buffer water trough from the side of the slope;

[0037] Step 4: Drive anchor bolts with second anchor heads into the slope, with the anchor bolts distributed in positions corresponding to the assembly holes and half-hole slots;

[0038] Step 5: Lay the precast frame according to the distribution of the anchor bolts corresponding to the distribution of the assembly holes and half-hole slots as preset in Step 4.

[0045] The geotechnical slope reinforcement method of this invention is based on a geotechnical slope reinforcement skeleton structure. First, the structure uses prefabricated frames, and then uses a splicing and fixing mechanism to connect the prefabricated frames to form a whole reinforcement skeleton. The prefabricated frames are individual structures, and local structural damage can be repaired by replacing individual prefabricated frames, saving construction time and cost, and better ensuring the stability of the overall slope reinforcement skeleton structure. In addition, the buffer water trough combined with the horizontal drainage pipe and the drainage channel on the prefabricated frame can guide the water flow and drain it in a timely manner, alleviate excessive water flow and flooding, avoid soil erosion and prefabricated frame settlement, and the traction rope also prevents the prefabricated frame from landslide, improving the stability of the slope reinforcement.

[0046] In summary, this slope reinforcement framework structure and reinforcement method features a prefabricated structure, which improves construction efficiency, facilitates the replacement of prefabricated components, saves construction costs, and ensures the stability of the entire structure for slope reinforcement, thus achieving better reinforcement effects on geotechnical engineering slopes.

[0062] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0063] Please see Figure 1-12 A geotechnical engineering slope reinforcement framework structure, comprising:

[0064] Buffer water tank 1 is set on the ground adjacent to the slope above, and is used to replenish water at a higher point in the direction of water flow to avoid rainwater flooding and causing disasters such as landslides.

[0065] The positioning pipe 2 has one end vertically inserted into the ground above the slope and the other end extending upward to the bottom of the buffer trough 1. The positioning pipe 2 is arranged in multiple sets at intervals along the extension direction of the buffer trough 1. The lower end of the positioning pipe 2 inserted into the ground is provided with a first anchor head to prevent the positioning pipe 2 from moving upward and detaching from the ground. In addition, the positioning pipe 2 can also introduce the rainwater buffered by the buffer trough 1 into the ground to avoid excessive rainwater overflowing the buffer trough 1 and to prevent rainwater flooding from causing landslides and other disasters.

[0066] The precast frame 3 consists of multiple sets laid on the slope, which are longitudinally connected end to end and laterally connected to form a grid shape on the slope. The uppermost set of precast frames 3 on the slope is connected to the upper end of the positioning pipe 2 by a traction rope 4. The positioning pipe 2 is inserted into the ground. With the traction of the traction rope 4, the position of the precast frame 3 on the slope is effectively stabilized, avoiding the precast frame 3 from sliding on the slope and causing landslides or unstable fixation, thereby improving the overall stability of the slope reinforcement frame.

[0067] A horizontally placed drainage pipe 5 has one end connected to the buffer water tank 1 and the other end extending from the slope surface and through the precast frame 3 to help drain the water accumulated in the buffer water tank 1. The inner diameter of the horizontally placed drainage pipe 5 forms a fixed water flow rate to evenly discharge the accumulated water and avoid erosion of the slope.

[0068] Anchor rod 6 has one end inserted into the slope with a second anchor head at the inserted end, and the other end extends out from the slope surface and through the precast frame 3. A pair of anchor rods 6 are distributed on each of the two horizontal side frames of the precast frame 3. The anchor rods 6 are used to fix the individual precast frame 3 to prevent landslides. Furthermore, by pre-setting the anchor rods 6 before installing the precast frame 3, the precast frame 3 can be pre-positioned. This also prevents the precast frame 3 from sliding or shifting during installation, making the overall installation of the slope reinforcement structure more convenient and faster.

[0069] The splicing and fixing mechanism is set between two adjacent precast frames 3 that are joined end to end in the longitudinal direction to connect and fix the two precast frames 3 and fix the precast frames 3 on the slope. Thus, after the precast frames 3 are spliced ​​and fixed, they form a whole and have an integrated protective structure to more stably reinforce the slope. This reinforcement is achieved by fixing the precast frames 3 on the slope to intercept sand, gravel and other materials on the slope, so as to avoid soil erosion or landslides.

[0070] The splicing rope 7 is used to connect the two anchor rods 6 located in adjacent positions on the two adjacent precast frames 3, so as to further connect and fix the two adjacent precast frames 3, making the overall slope reinforcement skeleton structure more stable.

[0071] And the intercepting rope 8, which is connected between any two anchor rods 6 on the horizontal side frame of the precast frame 3. It is used to pull horizontally on the inner side of the precast frame 3 to fill the inner space of the precast frame 3, so as to achieve a more rigorous slope interception and further enhance the slope reinforcement effect.

[0072] Furthermore, the buffer water tank 1 is made of concrete and serves to store water.

[0073] Furthermore, the positioning tube 2 is a hollow tube structure, which serves both as an anchor for the anchor rod and as a water guide.

[0074] Furthermore, the first anchor head includes:

[0075] The first pointed cone 9 is a conical hollow shell structure with the pointed end facing downward. The upper end of the first pointed cone 9 is open, and the lower end of the positioning tube 2 extends into the interior of the first pointed cone 9 and is connected through the first connecting rib 30. The lower end of the positioning tube 2 is connected to the interior of the first pointed cone 9.

[0076] And the first opening 10, which is located on the side of the first pointed cone 9.

[0077] Specifically, the pointed structure of the first pointed cone 9 facilitates the reduction of resistance during the underground driving of the positioning tube 2. Furthermore, the first pointed cone 9 and the lower end of the positioning tube 2 are connected by the first connecting rib 30. During the driving of the positioning tube 2, the first opening 10 on the first pointed cone 9 allows mud and sand to enter the inner side of the first pointed cone 9, filling the interior of the first pointed cone 9. This results in a soil filling effect above the first pointed cone 9 after the positioning tube 2 is driven in, better preventing the first pointed cone 9 and the positioning tube 2 from moving upwards, thus avoiding upward movement of the positioning tube 2 and making its anchoring effect more stable.

[0078] Furthermore, the precast frame 3 is a precast concrete frame, which can be prefabricated in batches in advance, saving construction time and improving subsequent laying efficiency.

[0079] A set of precast frames 3 at the top of the slope is provided with drainage holes 11 through which the horizontal drainage pipe 5 passes, and then connects with the horizontal drainage pipe 5 to discharge the stored water.

[0080] Both sides of the horizontal frame 3 are provided with longitudinally extending drainage channels 12. Drainage holes 11 are connected to drainage channels 12. Drainage channels 12 guide water flow and prevent water from flowing into the inside of the precast frame 3 and causing soil erosion.

[0081] The precast frame 3 has mounting holes 13 on both horizontal side frames for the corresponding anchor rods 6 to pass through, so that the precast frame 3 can be fixed by the anchor rods 6.

[0082] Furthermore, the end of the anchor rod 6 that extends out of the slope has an external thread and is provided with a limiting top plate 14 that is threadedly engaged with the external thread. The limiting top plate 14 can be replaced with a nut, which is tightened onto the precast frame 3 to fix the precast frame 3 in conjunction with the anchor rod 6, or the limiting top plate 14 limits the installation of other connecting parts.

[0083] Furthermore, the second anchor head includes:

[0084] The second pointed cone 15 is a conical hollow shell structure with the pointed cone end facing downward. The upper end of the second pointed cone 15 is open, and the lower end of the anchor rod 6 extends into the interior of the second pointed cone 15 and is connected by the second connecting rib 31.

[0085] And a second opening 16, which is located on the side of the second pointed cone 15.

[0086] Specifically, the pointed structure of the second pointed cone 15 facilitates the reduction of resistance during the underground driving of the anchor rod 6. Furthermore, the second pointed cone 15 is connected to the lower end of the anchor rod 6 via the second connecting rib 31. During the driving of the anchor rod 6, the second opening 16 on the second pointed cone 15 allows mud and sand to enter the inner side of the second pointed cone 15, filling the interior of the second pointed cone 15. This results in a soil filling effect above the second pointed cone 15 after the anchor rod 6 is driven in, better preventing the second pointed cone 15 and the anchor rod 6 from moving upwards, thus avoiding upward movement of the anchor rod 6 and making its anchoring effect more stable.

[0087] Furthermore, the splicing and fixing mechanism includes:

[0088] A strip-shaped protrusion 17 is horizontally positioned at the end of the precast frame 3 in the longitudinal direction. A through half-hole groove 18 is provided on the strip-shaped protrusion 17 at the edge of the end of the precast frame 3 in the longitudinal direction. After the two precast frames 3 are joined end to end in the longitudinal direction, the two corresponding strip-shaped protrusions 17 are joined together to form a hole through which the anchor rod 6 passes.

[0089] And an arc-shaped cover plate 19, which is an arc-shaped plate structure and is fastened on the two protrusions 17 that have been connected. The arc-shaped cover plate 19 has holes through which the anchor rod 6 passes and corresponds to the hole position formed by the two half-hole grooves 18. The anchor rod 6 passing through the hole on the arc-shaped cover plate 19 is pressed and fixed to the arc-shaped cover plate 19 by a nut 20.

[0090] During the specific installation process, after two adjacent strip-shaped protrusions 17 are brought together, a hole is formed for the anchor rod 6 to pass through. The arc-shaped cover plate 19 is then placed over the two strip-shaped protrusions 17, and the anchor rod 6 passes through the hole in the arc-shaped cover plate 19. The arc-shaped structure of the arc-shaped cover plate 19 can prevent the two strip-shaped protrusions 17 from separating from each other. Then, the anchor rod 6 is tightened and fixed by screwing on the nut 20, thereby making the arc-shaped cover plate 19 firmly connect and fix the two strip-shaped protrusions 17, thus realizing the connection and fixation of the two prefabricated frames 3 in the longitudinal direction.

[0091] Furthermore, splicing ropes 7 are connected between two longitudinally adjacent anchor rods 6 on two adjacent precast frames 3 that are joined end-to-end longitudinally, and between two laterally adjacent anchor rods 6 on two adjacent precast frames 3 that are opposed laterally. This further assists in fixing the connection between the precast frames 3. The splicing ropes 7 can be steel wires or other chain-like ropes, which serve to tighten the connection.

[0092] A slope reinforcement method based on a geotechnical engineering slope reinforcement framework structure includes the following steps:

[0093] Step 1: Drive the positioning tube 2 with the first anchor head into the ground adjacent to the slope. It can be driven downward by pressing directly or rotating and extending. Then the first anchor head prevents the positioning tube 2 from moving upward, making its anchoring function more stable.

[0094] Step 2: Pour a water-retaining buffer trough 1 on the ground adjacent to the slope and extend the upper end of the positioning pipe 2 from the bottom of the buffer trough 1, so that water can be stored above the slope through the buffer trough 1, and then the water is introduced into the ground through the positioning pipe 2 to prevent rainwater from directly flooding down and causing disasters such as landslides.

[0095] Step 3: Drive horizontal drainage pipes 5 into the buffer water trough 1 from the side of the slope to further assist in uniform drainage and avoid soil erosion caused by disorderly drainage.

[0096] Step 4: Drive anchor rods 6 with second anchor heads into the slope. The anchor rods 6 are distributed in positions corresponding to the assembly holes 13 and half-hole grooves 18. Only anchoring according to the corresponding dimensions is required. This also serves to pre-position the precast frame 3, and allows the precast frame 3 to be directly installed in the position later, improving installation efficiency.

[0097] Step 5: Lay the precast frame 3 according to the distribution of the anchor rods 6 corresponding to the assembly holes 13 and half-hole grooves 18 as preset in Step 4. The precast frame 3 is set with the ends connected longitudinally and the sides connected laterally. The anchor rods 6 and the precast frame 3 are connected by setting a limiting top plate 14 on the anchor rods 6. Laterally, the splicing rope 7 is tied between the two anchor rods 6 and fixed by limiting top plate 14. The splicing rope 7 and the intercepting rope 8 can be fixed by limiting top plate 14.

[0098] Step 6: Connect and fix the two adjacent precast frames 3 that are joined end to end in the longitudinal direction using the splicing and fixing mechanism, and fix the precast frames 3 on the slope, so that multiple precast frames 3 are connected into a whole structure, thereby more stably reinforcing the slope.

[0099] Step 7: Set up splicing ropes 7 to connect two adjacent prefabricated frames 3, and then fix them by limiting the top plate 14 to complete the connection and fixation of the prefabricated frame 3 as a whole.

[0100] Step 8: Set the interception rope 8 on the precast frame 3. It is used to stretch horizontally on the inner side of the precast frame 3 to fill the inner space of the precast frame 3, so as to achieve a more rigorous slope interception and further enhance the slope reinforcement effect.

[0101] The splicing and fixing mechanism includes a strip protrusion 17, which is horizontally set at the end of the precast frame 3 in the longitudinal direction. A through half-hole groove 18 is opened on the strip protrusion 17 at the edge of the end of the precast frame 3 in the longitudinal direction. After the two precast frames 3 are joined end to end in the longitudinal direction, the two corresponding strip protrusions 17 are joined together to make the two half-hole grooves 18 join together to form a hole through which the anchor rod 6 passes.

[0102] The above methods are simple and convenient to use, save construction time, and make the slopes more stable. They are also less susceptible to landslides and other disasters caused by rainwater flooding, and more effectively prevent soil erosion.

[0103] In another embodiment of the geotechnical engineering slope reinforcement framework structure of the present invention, see [reference needed]. Figure 1 , 2 3 and 8 are designed to address the different geological characteristics of slopes in geotechnical engineering and enhance the interception rope 8's functions in intercepting landslides and soil erosion. By replacing the interception rope 8, more targeted interception can be achieved. For example, in the case of slopes with silty soil, a covering component is further installed inside the precast frame 3 to replace the interception rope 8, and the silt on the slope can be intercepted more effectively to prevent soil erosion.

[0104] Furthermore, the covering component includes a first rectangular frame 21, which is disposed inside the precast frame 3. First connecting rings 22 are provided on both sides of the first rectangular frame 21 for connecting the first rectangular frame 21 to the inside of the precast frame 3 by being sleeved on the anchor rod 6 and fixed by the limiting top plate 14. A first intercepting net 23 is provided inside the first rectangular frame 21 for intercepting mud and sand on the slope. The mesh size of the first intercepting net 23 is determined according to the actual situation to more effectively intercept mud and sand.

[0105] In another embodiment of the geotechnical engineering slope reinforcement framework structure of the present invention, see [reference needed]. Figure 1 , 2 In addition to the different geological characteristics of slopes in geotechnical engineering, including situations with large amounts of rainwater, which can lead to soil erosion, this geotechnical engineering slope reinforcement framework structure has a good drainage effect to reduce the erosion of slope soil by rainwater and slow down soil erosion. Therefore, in this embodiment, the intercepting rope 8 is replaced with a drainage component for drainage assistance.

[0106] Furthermore, the drainage component includes a second rectangular frame 24, which is disposed inside the precast frame 3. Second connecting rings 25 are provided on both sides of the second rectangular frame 24 for connecting the second rectangular frame 24 to the inside of the precast frame 3 by being sleeved on the anchor rod 6 and fixed by the limiting top plate 14. Water guide plates 26 are provided on the second rectangular frame 24. The water guide plates 26 are arranged longitudinally and are arranged in multiple sets at intervals to maximize water guidance and prevent soil erosion. The multiple sets of water guide plates 26 at intervals cover the slope and play a good slope reinforcement role.

[0107] Furthermore, the water guide plate 26 has a V-shaped cross section to form a channel structure for water guidance. It is not limited to a V-shaped cross section shape, but can also be other shapes of flow channels to achieve the effect of guiding water flow.

[0108] In another embodiment of the geotechnical engineering slope reinforcement framework structure of the present invention, see [reference needed]. Figure 1 , 2 3, 10, 11, 12. For different geological characteristics of geotechnical engineering slopes, including the situation where there are many large and small stones on the slope, large and small stones are easy to roll off the slope. Relying solely on the interception rope 8 is insufficient to intercept the rolling stones. Therefore, the interception rope 8 is replaced with a rock-blocking component to intercept the rolling stones.

[0109] Furthermore, the boulder blocking assembly includes a third rectangular frame 27, which is disposed inside the precast frame 3. The upper and lower ends of the third rectangular frame 27 are connected to a low baffle 28. Both ends of the low baffle 28 are rotatably connected to the inside of the precast frame 3. The specific connection can be made by a support shaft and bearings, so that the low baffle 28 and the third rectangular frame 27 can rotate around this axis. A second intercepting net 29 for intercepting boulders is disposed inside the third rectangular frame 27.

[0110] Specifically, under normal circumstances, when no rocks are rolling down, the third rectangular frame 27 rotates to the inside of the precast frame 3. At this time, the low baffle 28 stands upright, preventing small stones from rolling down. When larger rocks are rolling down, the low baffle 28 cannot intercept them, but the impact of the larger rocks causes the low baffle 28 to rotate, which in turn causes the third rectangular frame 27 to rotate to an upright position. This allows the second intercepting net 29 to intercept the subsequent rolling down of larger rocks, preventing the rockfall hazard from escalating. At the same time, the third rectangular frame 27 and its second intercepting net 29 also serve to reinforce and protect the slope.

[0111] The geotechnical slope reinforcement method of this invention is based on a geotechnical slope reinforcement skeleton structure. First, the structure uses prefabricated frames, and then uses a splicing and fixing mechanism to connect the prefabricated frames to form a whole reinforcement skeleton. The prefabricated frames are individual structures, and local structural damage can be repaired by replacing individual prefabricated frames, saving construction time and cost, and better ensuring the stability of the overall slope reinforcement skeleton structure. In addition, the buffer water trough combined with the horizontal drainage pipe and the drainage channel on the prefabricated frame can guide the water flow and drain it in a timely manner, alleviate excessive water flow and flooding, avoid soil erosion and prefabricated frame settlement, and the traction rope also prevents the prefabricated frame from landslide, improving the stability of the slope reinforcement.

[0112] In summary, this slope reinforcement framework structure and reinforcement method features a prefabricated structure, which improves construction efficiency, facilitates the replacement of prefabricated components, saves construction costs, and ensures the stability of the entire structure for slope reinforcement, thus achieving better reinforcement effects on geotechnical engineering slopes.

[0113] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
