Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a cutting slope protection structure applied to dynamic design. Background Art

[0002] Roadbed slopes, as a crucial component of railways and highways, bear the crucial responsibility of supporting the road surface and protecting the natural slope. Based on the route location and specific technical requirements, portions of the geological mass are transformed into artificial structures, forming strip-like structures that provide a solid foundation for the road. However, the stability of roadbed slopes faces numerous challenges, particularly the influence of the natural slope's stability, geological conditions, and the degree of human modification.

[0003] In recent years, the concept of dynamic design has been widely used in slope protection projects. Dynamic design makes necessary adjustments and additions to slope protection structures based on the geological survey data of the project under construction and the actual situation during the construction process to ensure the stability and safety of the slope. For slopes with poor stability, it is necessary to promptly adjust the protection or add support reinforcement measures based on the geological conditions and slope structure revealed during construction. However, in the natural environment, heavy rain and debris flow are the main factors threatening the stability of road cutting slopes. These natural disasters have a strong impact force and can quickly destroy the soil structure of the slope, causing the slope to become unstable. Once the slope becomes unstable, it will directly threaten the safety and smooth flow of the road. Slope collapse will not only cause serious damage to the natural slope, but may also block the road, causing great trouble to transportation.

[0004] Therefore, in view of this, the inventors propose a road cutting slope protection structure applied to dynamic design to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a road cutting slope protection structure applied to dynamic design, so as to solve the problem that traditional slopes are easily affected by heavy rain or debris flow, resulting in mountain instability and slope collapse.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0016] Furthermore, a platform intercepting ditch is provided on the top of the base.

[0017] Furthermore, the slope supporting member includes a three-dimensional net and a connecting piece, the number of the three-dimensional net is multiple, and the three-dimensional nets are arranged at intervals along the third direction;

[0018] Each of the three-dimensional nets is laid on the surface of the slope, and the connecting piece is used to fix the three-dimensional net on the slope.

[0019] Furthermore, the connecting piece includes a U-shaped fixing nail and a plurality of barbs, the number of the barbs is multiple, and the barbs are arranged on the U-shaped fixing nail at intervals.

DETAILED DESCRIPTION

[0036] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended solely to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0038] This embodiment proposes a road cutting slope protection structure for dynamic design, such as Figures 1 to 7 As shown, it is used to be installed on the slope 4 below the roadbed 1. The slope 4 protection structure includes a roadbed support component 2 and a slope support component 3. The roadbed support component 2 is arranged below the slope support component 3. The roadbed support component 2 is the foundation of the entire protection structure. The roadbed support component 2 includes a ground pile 21, a base 22 and a first anchor 23; one end of the ground pile 21 is connected to the base 22, and the other end is connected along the first direction (that is, corresponding to the first direction). Figure 1The ground piles 21 extend deep into the ground to provide stable support for the entire structure. The number of the ground piles 21 is at least two to ensure the stability of the structure.

[0039] In this embodiment, the base 22 is a concrete structure composed of a steel mesh / steel cage and cement. It is located above and connected to the ground pile 21. The base 22 includes a first steel bar 221 and a second steel bar 222. The number of the first steel bar 221 and the second steel bar 222 is two or more. The first steel bar 221 is arranged parallel to the third direction, while the second steel bar 222 is arranged parallel to the second direction. The first direction, the second direction, and the third direction are perpendicular to each other. The first steel bar 221 and the second steel bar 222 are tied together to form a steel mesh, and finally cement is poured and cured to form a concrete structure with sufficient strength and stability. The arrangement of the ground pile 21 and the base 22 can better resist the lateral pressure from the slope 4, preventing the mountain from becoming unstable and collapsing, which would cause road obstruction.

[0040] As a preferred embodiment, one end of the first anchor 23 (i.e. Figure 1 The left end of the first anchor 23) is connected to the base 22, and the other end (i.e. Figure 1 The right end of the first anchor 23 in the sidewall extends into the slope 4 and is tightly integrated with the soil of the slope 4. In this way, the first anchor 23 can transmit the stabilizing force of the base 22 to the soil of the slope 4, thereby enhancing the stability of the slope 4. There are multiple first anchors 23, which are arranged parallel to each other, and the depth of their extension into the slope 4 gradually increases from bottom to top.

[0041] As a preferred embodiment, Figure 3 As shown, the first anchor 23 and the first steel bar 221 are fixed by welding. When the first anchor 23 is fixed to the first steel bar 221 outside the slope surface of the slope 4, the first anchor 23 is tightened and limited, which can be effectively transmitted to the entire base 22, thereby forming a stable overall structure, which helps to prevent the slope 4 from sliding or collapsing when subjected to external forces (such as heavy rain, mudslides and other natural disasters), thereby enhancing the stability of the slope 4.

[0042] As a preferred embodiment, Figure 1 and Figure 2 As shown, a shoulder 5 is provided on the side of the roadbed 1, and a drainage pipe 6 is arranged in the shoulder 5. By providing the drainage pipe 6 in the shoulder 5, rainwater can be discharged in time, reducing the accumulation of water in the roadbed 1, thereby reducing the scouring and erosion of the roadbed 1 by rainwater and extending the service life of the roadbed 1.

[0043] As a preferred embodiment, Figure 1As shown, a platform intercepting ditch 7 is provided on the top of the base 22 , which can collect and guide rainwater on the surface of the slope 4 to prevent the rainwater from soaking the slope 4 , thereby further enhancing the stability of the slope 4 .

[0044] It should be noted that the first anchoring member 23 and the second anchoring member 34 mentioned in the present invention are both anchor rods.

[0045] As a preferred embodiment, this embodiment further includes a data collector (not shown); stress sensors (not shown) are provided on the first anchor 23 and the second anchor 34, and a plurality of humidity sensors (not shown) are provided in the slope 4. The humidity monitoring is used to monitor the moisture content of the soil or rock mass of the slope (4); the stress sensors and the humidity sensors are connected to the data collector in a wired or wireless manner.

[0046] Preferably, the stress sensor may be a strain gauge, a pressure box or a hydraulic pillow, and the humidity sensor may be a soil moisture sensor; the stress gauge is installed at the key position of the anchor rod (such as the center position of the anchor rod, the end of the anchor rod, etc.) to monitor the stress changes of the anchor rod during the stress process. By analyzing the stress data, the working state of the anchor rod and the stability of the slope 4 can be judged. When the stress of the anchor rod is found to be abnormal or the data detected by the humidity sensor is abnormal, timely inspection and necessary reinforcement measures are taken to achieve the purpose of dynamic monitoring. It should be noted that, since there is already a technology in the prior art that monitors the stress state of the slope 4 in real time by installing a stress sensor on the anchor rod and installing a humidity sensor in the slope 4, it is a technology well known to technicians in the relevant technical field and will not be described in detail here.

[0047] The slope supporting member 3 is located on the surface of the slope 4 and is used to further fix and protect the slope 4 .

[0048] Example 1

[0049] In this embodiment, if Figures 1 to 5 As shown, the slope support member 3 includes a three-dimensional net 31 and a connecting member 32. In this embodiment, as shown in FIG. Figure 5 As shown, the three-dimensional net 31 is laid on the surface of the slope 4 in a grid-like structure and is tightly connected to the soil of the slope 4 through the connecting piece 32. When the grid structure of the three-dimensional net 31 is laid on the surface of the slope 4, the stability of the soil is increased and mud and rocks are prevented from falling. In this embodiment, there are multiple three-dimensional nets 31, which are arranged along the third direction (i.e. Figure 2 in the horizontal direction) to ensure full coverage of the slope 4.

[0050] Furthermore, the connecting member 32 includes a U-shaped fixing nail 321 and a plurality of barbs 322. The U-shaped fixing nail 321 is inserted into the soil of the slope 4, and the barbs 322 are fixedly set on the U-shaped fixing nail 321. By setting the barbs 322, it is convenient to firmly fix the connecting member 32 on the slope 4, so as to improve the stability of the three-dimensional net 31 on the slope 4.

[0051] When natural disasters such as heavy rain or mudslides occur, they will produce a huge impact force on the slope 4. However, due to the presence of the roadbed support component 2 and the slope support component 3 of the utility model, these impact forces are effectively dispersed and resisted. First, the ground piles 21 and base 22 in the roadbed support component 2 provide a stable support foundation for the entire structure. Through the ground piles 21 and base 22 structure deep in the ground, the lateral pressure of the soil on the slope 4 is effectively transmitted to the soil deeper below the ground. Secondly, the first anchor 23 transmits the stabilizing force of the base 22 to the soil on the slope 4, thereby enhancing the stability of the lower part of the slope 4. The three-dimensional net 31 and connector 32 in the slope support member 3 further fix and protect the upper part of the slope 4. The grid structure of the three-dimensional net 31 can disperse the impact of rainwater and debris flow on the slope 4, while the connector 32 firmly fixes the three-dimensional net 31 on the slope 4 through the design of U-shaped fixing nails 321 and barbs 322, which can effectively resist the impact of heavy rain and debris flow and prevent the slope 4 from becoming unstable and collapsing.

[0052] Example 2

[0053] In this embodiment, slope support member 3 includes lattice frame beams 33 and second anchors 34. Lattice frame beams 33 employ a frame-like structure made of high-strength material, or alternatively, concrete. They are laid on the surface of slope 4 and tightly bonded to the soil of slope 4 via second anchors 34. The design of lattice frame beams 33 provides a sturdy support platform on the surface of slope 4, preventing it from sliding or collapsing when subjected to external forces.

[0054] Furthermore, the lattice frame beam 33 is also provided with a hollow cavity, which is used to reduce the weight of the lattice frame beam 33 and facilitate installation; a grid mesh 35 is installed in the hollow cavity, which can further disperse the impact of rainwater and debris flow on the slope 4, while increasing the cohesion of the soil on the slope 4.

[0055] One end of the second anchor 34 is connected to the lattice frame beam 33, and the other end extends into the interior of the slope 4 and is tightly combined with the soil of the slope 4. In this way, the second anchor 34 can transfer the stabilizing force of the lattice frame beam 33 to the soil of the slope 4, and distribute the remaining downward force or soil pressure and rock pressure of the slope 4 to the second anchor 34 at the node of the lattice frame beam 33, and then transfer it to the stable slope through the second anchor 34, so that the slope 4 is in a stable state under the action of the anchoring force provided by the second anchor 34, thereby enhancing the stability of the slope 4.

[0056] In this embodiment, if Figure 6 and Figure 7 As shown, the second anchor 34 is further provided with an exposed ring 341 , and a geotextile rope 36 is connected to the adjacent exposed ring 341 . The geotextile rope 36 is wound around the exposed ring 341 and the lattice frame beam 33 to prevent falling rocks and flying rocks.

[0057] As a preferred embodiment, the geotextile rope 36 is connected to the second anchor rod and the lattice frame beam 33. The geotextile rope 36 can be woven into a steel rope net, and one or two 4m×4m or 4m×2m DO / 08 / 300 type steel rope nets are laid. The steel rope net formed by each geotextile rope 36 is sewn to the surrounding lattice frame beams 33 and pre-tightened. The tensioned geotextile rope 36 applies a certain normal pre-tightening pressure to the slope surface, thereby improving the stability of the surface dangerous rock mass and preventing the collapse of small-sized rock blocks on the slope 4. The structure is compact and practical, and solves the problem that the traditional slope 4 is easily affected by heavy rain or mudslides, resulting in mountain instability and collapse of the slope 4.

[0058] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
