Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slope protection, and more particularly to a slope protection structure. BACKGROUND

[0002] With the gradual promotion of underground space utilization by buildings, the excavation of foundation pits is becoming deeper and deeper, and the stability and safety of foundation pits are increasingly valued by people. The traditional method of using wire mesh and spraying concrete to form a protective surface is prone to cracking when the slope is steep.

[0003] With the increasing environmental awareness and continuous innovation of building technology, the GRF (Green, Recycle, Fabricated) green foundation pit slope support technology has emerged as the times require. The GRF fabricated slope protection material is composed of geotextile and reinforced mesh. The role of geotextile is to block the erosion of rainwater, prevent soil particles from being lost, avoid the problem of slope instability caused by soil particles being carried away by water flow, and ensure the stability of the soil structure of the slope. The reinforced mesh has a certain tensile strength and can withstand the pressure on the slope surface, reinforcing the slope surface and enhancing the stability of the slope surface.

[0004] Anchor points are buried around the slope, and the GRF fabricated slope protection material is laid down from the anchor points on the top of the slope as the lapping points, and the adjacent GRF materials are stitched together, and then the steel wires are pressed on the GRF surface layer in the transverse and longitudinal directions, and the two ends of the steel wires are fixed on the anchor points.

[0005] The GRF technology has the characteristics of fast construction speed and high efficiency, and the fabricated construction method simplifies the construction process, reduces the amount of on-site work and construction difficulty, and improves the construction efficiency. However, the GRF protection process still has a certain probability of slope collapse, and the current GRF protection process cannot automatically indicate the slope loosening displacement, and often cannot be discovered and maintained until after the slope collapse occurs, and the maintenance after the slope collapse is difficult and time-consuming. SUMMARY

[0006] In view of the problem that the GRF protection process still has a certain probability of slope collapse, and the current GRF protection process cannot automatically indicate the slope loosening displacement, and often cannot be discovered and maintained until after the slope collapse occurs, and the maintenance after the slope collapse is difficult and time-consuming, the present application provides a scheme that can moderately indicate the deformation condition of the slope surface.

[0007] A slope protection structure includes a flexible protection unit. The flexible protection unit includes a fabricated protection surface, a first direction rope, a second direction rope, and a node assembly. The node assembly includes an outer cylinder, an inner cylinder, a first sliding block, a first spring, an outer core tube, a second sliding block, a second spring, an inner core rod, a base plate, a first indicating mechanism, and a second indicating mechanism.

[0008] The assembled protective cover is applied to the slope surface. The outer cylinder is embedded in the slope. The inner cylinder is fixed within the outer cylinder. The base plate is fixed to the outer end of the inner cylinder. The first indicating mechanism and the second indicating mechanism are mounted on the base plate. The inner cylinder has a first sliding cavity, a first pair of clearance holes, a second sliding cavity, and a second pair of clearance holes. The first pair of clearance holes are located on both sides of the first sliding cavity. The second pair of clearance holes are located on both sides of the second sliding cavity.

[0009] The first spring and the first slider are installed in the first sliding cavity, with both ends of the first spring connecting the cavity wall of the first sliding cavity and the first slider. One end of the outer core tube is fixed to the first slider, and the other end movably passes through the base plate. The first directional rope wraps around the bottom side of the first slider, with both ends of the first directional rope passing through the first pair of clearance holes and exiting between the base plate and the outer cylinder to press against the assembled protective surface. The outer core tube cooperates with the first indicating mechanism to indicate the slope deformation state of the adjacent first directional rope positions.

[0010] The second spring and the second slider are installed in the second sliding cavity, with both ends of the second spring connecting the cavity wall and the second slider. One end of the inner core rod fixes the second slider, and the other end coaxially passes through the interior of the outer core tube to the outside of the substrate. The second directional rope wraps around the bottom side of the second slider, with both ends of the second directional rope passing through the second pair of clearance holes and exiting between the substrate and the outer cylinder to press against the assembled protective surface. The inner core rod, in conjunction with the second indicating mechanism, indicates the slope deformation state at the position of the adjacent second directional rope.

[0011] By employing the above technical solution, when a slope becomes loose and deformed, the slope bulges outward, compressing the first directional rope and / or the second directional rope. If the first directional rope is compressed, it pulls the outer core tube outward, and the outer core tube, in conjunction with the first indicating mechanism, indicates the slope condition at the position of the adjacent first directional rope. If the second directional rope is compressed, it pulls the inner core rod outward, and the inner core rod, in conjunction with the second indicating mechanism, indicates the slope condition at the position of the adjacent second directional rope. This mechanism can detect abnormal slope deformation in advance, allowing for timely repairs and reducing maintenance difficulty and time.

[0012] In a preferred embodiment of the slope protection structure, the outer core tube passes through the interior of the first spring, and the inner core rod passes through the interior of the second spring.

[0013] By adopting the above technical solution, the internal space of the inner cylinder is saved, and the outer core tube and the first spring can move stably coaxially, while the inner core rod can move stably coaxially with the second spring.

[0014] A preferred embodiment of this slope protection structure is that the inner cylinder is a regular square prism shell, and both the first and second sliding cavities are regular square prisms. The first slider is a cylinder with a diameter equal to its length, and is embedded in the first sliding cavity. The second slider is a cylinder with a diameter equal to its length, and is embedded in the second sliding cavity.

[0015] By adopting the above technical solution, the first slider and the second slider can move coaxially and stably, so that the inner core rod and the outer core tube can move coaxially and stably, and save space and reduce the size of the mechanism.

[0016] A preferred embodiment of the slope protection structure is that the node assembly includes a first connecting portion and a first pressing straight triangular prism. One end of the first connecting portion is fixed to the side wall of the outer core tube, and the other end is fixedly connected to the first pressing straight triangular prism. The first indicating mechanism includes a first guide shell, a first displacement spring, a first bearing straight triangular prism, a first pointer, and a first indicator plate. The first guide shell is fixed to the base plate, and the first displacement spring and the first bearing straight triangular prism are installed in the first guide shell. The two ends of the first displacement spring are respectively fixed to the inner wall of the first guide shell and the first bearing straight triangular prism. The first guide shell has an opening on the side facing the first pressing straight triangular prism, exposing the side slope of the first bearing straight triangular prism, which is in contact with the side slope of the first pressing straight triangular prism. The first pointer is fixed to the first bearing straight triangular prism. The first indicator plate is fixed to the base plate. The movement of the outer core tube causes the first pressing straight triangular prism to move, driving the first bearing straight triangular prism to move, and the first pointer points to different positions of the first indicator plate.

[0017] By adopting the above technical solution, when the outer core tube is driven to move outward by the first directional rope, the first pressing straight triangular prism moves outward synchronously. Then, the first pressure-bearing straight triangular prism moves together with the first pointer and points to the position marked by the first indicator sign where the slope deformation is large. Conversely, the first pointer points to the position marked by the first indicator sign where the slope deformation is small.

[0018] A preferred embodiment of this slope protection structure is that the node assembly includes a second connecting portion and a second pressing straight triangular prism. One end of the second connecting portion is fixed to the side wall of the inner core rod, and the other end is fixedly connected to the second pressing straight triangular prism. The outer core tube has a third clearance hole along its axial direction, and the second connecting portion can slide freely along the third clearance hole.

[0019] The second indicating mechanism includes a second guide shell, a second displacement spring, a second pressure-bearing triangular prism, a second pointer, and a second indicator plate. The second guide shell is fixed to the base plate, and the second displacement spring and the second pressure-bearing triangular prism are installed within the second guide shell. The two ends of the second displacement spring are respectively fixed to the inner wall of the second guide shell and the second pressure-bearing triangular prism. The second guide shell has an opening on the side facing the second pressure-bearing triangular prism, exposing the beveled side of the second pressure-bearing triangular prism, which is then in contact with the beveled side of the second pressure-bearing triangular prism. The second pointer is fixed to the second pressure-bearing triangular prism. The second indicator plate is fixed to the base plate. Movement of the inner core rod causes the second pressure-bearing triangular prism to move, and the second pointer points to different positions on the second indicator plate.

[0020] By adopting the above technical solution, when the inner core rod is driven outward by the second directional rope, the second pressing straight triangular prism moves outward synchronously. Then, the second bearing straight triangular prism moves together with the second pointer, pointing to the location marked by the second indicator sign where the slope deformation is greater. Conversely, the second pointer points to the location marked by the second indicator sign where the slope deformation is smaller.

[0021] A preferred embodiment of this slope protection structure is that anchor bolts are embedded at the edge of the slope. The two outer ends of the first directional rope are fixed to the edge anchor bolts of the slope, and the two outer ends of the second directional rope are fixed to the edge anchor bolts of the slope.

[0022] By adopting the above technical solution, the outer ends of the first and second direction ropes are fixed, creating the basic conditions for measuring slope deformation.

[0023] A preferred embodiment of this slope protection structure is that the slope includes a gentle slope and a steep slope. The gentle slope is covered with concrete protection units, and the steep slope is covered with the flexible protection units. The vertical height:horizontal width value of the gentle slope is less than or equal to x, and the vertical height:horizontal width value of the steep slope is greater than x, where x is any number between 1.8 and 2.2.

[0024] By adopting the above technical solutions, if GRF prefabricated revetment is used on gentle slopes, the large permeability of the revetment and the large area for rainwater to be collected, combined with the slow downward flow of water, make it prone to water accumulation and increased hydrostatic pressure. This could cause the GRF prefabricated revetment to collapse and lead to a landslide. However, concrete revetment has low permeability and high strength, making it less likely for water to accumulate in the soil and thus less prone to landslides. Steep slopes have a smaller area for rainwater to be collected, and rainwater flows down the slope wall more efficiently. Rainwater is less likely to accumulate in the soil, resulting in a relatively smaller water storage capacity. Furthermore, GRF prefabricated revetment is less prone to cracking, while traditional concrete revetment is more likely to crack. Therefore, GRF prefabricated revetment is used on steep slopes, while traditional concrete revetment is used on gentle slopes.

[0025] A preferred embodiment of the slope protection structure includes a slope crest, a slope midsection, and a slope bottom. The slope crest connects to the upper edge of the gentle slope. The slope midsection connects to the lower edge of the gentle slope and the upper edge of the steep slope, and the slope bottom connects to the lower edge of the steep slope. The flexible protection unit extends to the slope midsection and the slope bottom. A concrete layer is poured over the flexible protection units on the slope midsection and the flexible protection units on the slope bottom.

[0026] By adopting the above technical solution, the upper and lower edges of the flexible faceplate unit are fixed and will not warp.

[0027] In summary, the slope protection structure of this application has the following beneficial effects: it can indicate the slope deformation status in real time. When the slope loosens and deforms, the slope bulges outward and presses the first directional rope and / or the second directional rope. If the first directional rope is pressed, the first directional rope pulls the outer core tube outward, and the outer core tube, in conjunction with the first indicating mechanism, indicates the slope status at the position of the adjacent first directional rope. If the second directional rope is pressed, the second directional rope pulls the inner core rod outward, and the inner core rod, in conjunction with the second indicating mechanism, indicates the slope status at the position of the adjacent second directional rope. The above mechanism can detect abnormal slope deformation in advance, and timely repairs can be carried out, reducing maintenance difficulty and maintenance time. Attached Figure Description

[0035] like Figure 1 A slope protection structure includes a flexible slope protection unit. The flexible slope protection unit includes a prefabricated slope protection 1, a first directional rope 2, a second directional rope 3, and a node assembly 4.

[0036] The prefabricated facing 1 can be a GRF facing, which is made of multiple overlapping GRF materials stitched together. The GRF material is a composite of geotextile and a grid-like reinforcing mesh.

[0037] During construction, several anchor points 5 are first driven into the slope edge. These anchor points 5 can be formed by inserting a threaded steel bar into the ground, with a short section protruding. Multiple rolls of GRF material are then hung one by one on the anchor points 5 at the top of the slope 6, and the GRF rolls are rolled downwards to overlap and cover the slope, stitching adjacent GRF materials together. Then, holes are drilled through the GRF material and into the soil, and node components 4 are inserted into the holes. Concrete can be injected between the node components 4 and the holes for waterproofing and fixation. The first directional rope 2 and the second directional rope 3 are laid, and both ends of the first directional rope 2 and the second directional rope 3 are fixed to the anchor points 5.

[0038] The first direction rope 2 can be a transverse steel rope, and the second direction rope 3 can be a longitudinal steel rope.

[0039] like Figure 2 , Figure 3 Node component 4 includes an outer cylinder 401, an inner cylinder 402, a first slider 403, a first spring 404, an outer core tube 405, a second slider 406, a second spring 407, and an inner core rod 408, as shown.Figure 4 , Figure 5 The node assembly 4 also includes a substrate 409, a first connecting portion 410, a first pressing straight triangular prism 411, a first indicating mechanism 412, a second connecting portion 413, a second pressing straight triangular prism 414, and a second indicating mechanism 415.

[0040] like Figure 3 The bottom end of the straight inner cylinder 402 with a square cross-section is fixed to the inner bottom surface of the circular outer cylinder 401, and is connected to the edge between the inner cylinder 402 and the outer cylinder 401 by a connecting rod 416 to strengthen the connection between the inner cylinder 402 and the outer cylinder 401. The opening of the outer cylinder 401 unfolds into a circular plate, which can cover the GRF material.

[0041] The inner cylinder 402 has a first sliding cavity 4021 and a second sliding cavity 4022 separated from each other, both with a square cross-section. A substrate 409 covers the outer end of the inner cylinder 402, thereby covering the first sliding cavity 4021. The substrate 409 can be square, circular, etc., and it is parallel to the unfolded surface of the outer cylinder 401 to form a sandwich.

[0042] A cylindrical first slider 403 is embedded in a first sliding cavity 4021, and the length of the first slider 403 is equal to its diameter. One end of a first spring 404 is fixed to the first slider 403, and the other end is fixed to the cavity wall of the first sliding cavity 4021. A portion of the outer core tube 405 passes through the first spring 404 and is fixed to the first slider 403, while the other portion of the outer core tube 405 movably protrudes from the substrate 409. A first connecting part 410 is a round rod, vertically connected to the outer end side of the outer core tube 405. A first pressing straight triangular prism 411 is fixed to the other end of the first connecting part 410.

[0043] The inner cylinder 402 has a first pair of axial clearance holes 4023 on both sides of the first sliding cavity 4021. The first directional rope 2 passes around the bottom side of the first slider 403, passes through the first pair of clearance holes 4023 at both ends, and passes between the base plate 409 and the cylinder opening of the outer cylinder 401, and then passes into the adjacent node assembly 4 or connects to the anchor point 5 at the edge of the slope. The first directional rope 2 presses on the assembled protective surface 1. The pressing here can be a close fit or with a small gap, such as a gap with a width of 1~3cm.

[0044] A cylindrical second slider 406 is embedded in a second sliding cavity 4022, and the length of the second slider 406 is equal to its diameter. The second slider 406 is perpendicular to the first slider 403. One end of the second spring 407 is fixed to the second slider 406, and the other end is fixed to the cavity wall of the second sliding cavity 4022. An inner core rod 408 passes through the center of the second spring 407. One end of the inner core rod 408 is fixed to the second slider 406, and the other end slides through the partition plate 4025 between the first sliding cavity 4021 and the second sliding cavity 4022, then moves through the first slider 403, and moves into the outer core tube 405 until it exits the outer core tube 405. The second connecting part 413 is a round rod, which is vertically connected to the side of the inner core rod 408, and the second pressing straight triangular prism 414 is fixed to the second connecting part 413. In order to prevent the movement of the outer core tube 405 and the inner core rod 408 from interfering with each other, an axial third clearance hole 4051 is opened on the side of the outer core rod. The second connecting part 413 based on the inner core rod 408 can move freely in the third clearance hole 4051 without obstruction, so that the outer core tube 405 can move outward without obstruction.

[0045] The inner cylinder 402 has a second pair of axial clearance holes 4024 on both sides of the second sliding cavity 4022. The second directional rope 3 passes around the bottom side of the second slider 406, and both ends of the second directional rope 3 pass through the second pair of clearance holes 4024, and then pass through the opening surface between the base plate 409 and the outer cylinder 401, and then pass into the adjacent node assembly 4 or connect to the anchor point 5 at the edge of the slope. The second directional rope 3 presses on the assembled protective surface 1. The pressing here can be a close fit or with a small gap, such as a gap with a width of 1~3cm.

[0046] like Figure 5 and Figure 6 The first indicating mechanism 412 includes a first guide shell 4121, a first displacement spring 4122, a first pressure-bearing right triangular prism 4123, a first pointer 4124, and a first indicator plate 4125. The first guide shell 4121 is fixed to the base plate 409, and the first displacement spring 4122 and the first pressure-bearing right triangular prism 4123 are installed within the first guide shell 4121. One end of the first displacement spring 4122 is fixed to the inner wall of the first guide shell 4121, and the other end is fixed to the first pressure-bearing right triangular prism 4123. One side of the first guide shell 4121 is open, exposing the inclined surface of the first pressure-bearing right triangular prism 4123. The first pointer 4124 is fixed to one end face of the first pressure-bearing right triangular prism 4123. The first indicator plate 4125 is fixed to the base plate 409. The first indicator plate 4125 has sequentially connected green, yellow, and red warning zones, representing slope deformation from smallest to largest. Initially, the first pointer 4124 points to the green zone.

[0047] The inclined surface of the first pressing straight triangular prism 411 is attached to the inclined surface of the first bearing straight triangular prism 4123. When the slope deforms and bulges outward, the first directional rope 2 is pulled, thereby pulling the first slider 403 to move along the first sliding cavity 4021, thereby driving the outer core tube 405 to move outward, and simultaneously driving the first pressing straight triangular prism 411 to move away from the substrate 409, reducing the pressing depth on the first bearing straight triangular prism 4123. Then, the first bearing straight triangular prism 4123 moves under the drive of the first displacement spring 4122, causing the first pointer 4124 to move accordingly. It can move in the green, yellow, and red warning ranges to indicate the corresponding risks.

[0048] The second indicating mechanism 415 has the same structure as the first indicating mechanism 412. The second indicating mechanism 415 includes a second guide shell 4151, a second displacement spring 4152, a second pressure-bearing straight triangular prism 4153, a second pointer 4154, and a second indicator plate 4155.

[0049] The second guide shell 4151 is fixed to the base plate 409, and the second displacement spring 4152 and the second pressure-bearing right triangular prism 4153 are installed inside the second guide shell 4151. One end of the second displacement spring 4152 is fixed to the inner wall of the second guide shell 4151, and the other end is fixed to the second pressure-bearing right triangular prism 4153. One side of the second guide shell 4151 is open, exposing the inclined surface of the second pressure-bearing right triangular prism 4153. The second pointer 4154 is fixed to one end face of the second pressure-bearing right triangular prism 4153. The second indicator 4155 is fixed to the base plate 409. The second indicator 4155 is provided with sequentially connected green, yellow, and red warning zones, which respectively represent the slope deformation from small to large. Initially, the second pointer 4154 points to the green zone.

[0050] The inclined surface of the second pressing straight triangular prism 414 is attached to the inclined surface of the second bearing straight triangular prism 4153. When the slope deforms and bulges outward, the second directional rope 3 is pulled, thereby pulling the second slider 406 to move along the second sliding cavity 4022, thereby driving the inner core rod 408 to move outward, and simultaneously driving the second pressing straight triangular prism 414 to move away from the base plate 409, reducing the pressing depth on the second bearing straight triangular prism 4153. Then, the second bearing straight triangular prism 4153 moves under the drive of the second displacement spring 4152, causing the second pointer 4154 to move accordingly. It can move in the green, yellow, and red warning ranges to indicate the corresponding risks.

[0051] The above flexible facing units are laid on steep slope 9, which has a slope gradient > 1 (vertical height): 0.5 (horizontal width). On slopes with a gradient ≤ 1 (vertical height): 0.5 (horizontal width), traditional concrete facing, i.e., wire mesh shotcrete facing, is used. Gentle slope 7 (gradient ≤ 1 (vertical height): 0.5 (horizontal width)) uses GRF prefabricated facing 1. This facing has high permeability and a large water-bearing area. The gentle slope makes it easy for water to accumulate and push up the GRF prefabricated facing 1, causing a landslide. However, traditional wire mesh shotcrete facing has low permeability and high strength, and the soil layer is less likely to accumulate water and push up the traditional wire mesh shotcrete facing, making it less prone to landslides. Steep slope 9 (slope > 1 (vertical height): 0.5 (horizontal width)) has a small rainwater catchment area, resulting in high efficiency of rainwater flowing down the slope. Rainwater is less likely to accumulate in the soil, leading to a relatively small water storage capacity. Furthermore, the GRF prefabricated revetment 1 is less prone to cracking, while traditional wire mesh shotcrete revetment is more likely to crack on steep slope 9. Therefore, steep slope 9 uses GRF prefabricated revetment 1, while gentle slope 7 uses traditional wire mesh shotcrete revetment.

[0052] For example, consider a slope of a foundation pit, consisting of a top (6), a gentle slope (7), a mid-slope (8), a steep slope (9), and a bottom (10), connected sequentially from top to bottom. The top (6), mid-slope (8), and bottom (10) are all horizontal. A traditional concrete facing unit is applied to the gentle slope (7), while a flexible facing unit is applied to the steep slope (9). The upper end of the GRF (Glass Reinforced Fiber Reinforced) facing extends to the mid-slope (8), and the lower end extends to the bottom (10). Concrete layers (11) are poured to secure the upper and lower ends of the GRF facing, preventing edge warping. This results in a composite slope protection structure suitable for various complex geological conditions.

[0053] In the slope protection structure of this application, when the slope below the first directional rope 2 deforms and arches outward, it will press against the first directional rope 2, thus pushing the first directional rope 2 to bend and move outward. The first directional rope 2, located in the adjacent two-sided node components 4, pulls the first slider 403 outward, compresses the first spring 404, and moves the outer core tube 405 outward. The first pointers 4124 of the two adjacent sets of node components 4 move respectively, pointing to the areas corresponding to the risk level on the first indicator 4125. By observing these indications, workers can know that a compression bulge has occurred on the slope between the two sets of node components 4, and can promptly compact and repair the slope in that area to prevent the adverse condition from worsening. This automatic indication and timely repair mechanism effectively ensures the stability of the slope. Similarly, when the slope below the second directional rope 3 deforms and arches outward, it will press against the second directional rope 3, thus pushing the second directional rope 3 to bend and move outward. The second directional rope 3 in the adjacent two-sided node components 4 will pull the second slider 406 outward, the second spring 407 will be compressed, the inner core rod 408 will move outward, and the second pointers 4154 of the two adjacent sets of node components 4 will move and point to the areas of the corresponding risk level of the second indicator 4155. Based on these indications, the staff can know that there is a squeezing and protrusion phenomenon on the slope between the two sets of node components 4. The staff can then carry out timely compaction and repair of the slope in that area to prevent the adverse condition from continuing to expand. This automatic indication and timely repair mechanism effectively ensures the stability of the slope.

[0054] The above description is only a preferred embodiment of this application. The protection scope of this application is not limited to the above embodiments. Other embodiments that make improvements and modifications without departing from the core principles of this application should also fall within the protection scope of this application.
