Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to the structural design of an embankment protection and reinforcement device. Background Technology

[0002] In transportation infrastructure construction, the stability of embankment slopes is a key factor in ensuring the safe operation and long-term durability of roads. As an important component of road engineering, embankments are constantly exposed to the natural environment and are highly susceptible to multiple factors, including rainwater erosion, surface water infiltration, weathering, and gravity. These factors can induce slope instability, leading to landslides along steep slope bases, toe erosion and collapse, and even serious disasters such as deep landslides. Therefore, systematic reinforcement and protection of embankment slopes are crucial. Installing protective reinforcement devices can effectively improve the overall stability of slopes, inhibit soil deformation, resist external environmental erosion, thereby preventing disasters, extending the service life of roads, and ensuring the smooth and safe operation of transportation networks.

[0003] With the development of engineering technology, cast-in-place concrete slope protection has gradually become a common method for reinforcing steep slopes due to its advantages such as high strength, good integrity, and strong erosion resistance. However, in actual construction, especially when using cast-in-place concrete on steep embankments, the concrete itself has a certain fluidity and self-weight, which makes it prone to sliding down the slope under gravity during pouring. This results in uneven distribution of concrete within the formwork, with the upper part becoming thinner and the lower part piling up, seriously affecting the geometric quality and load-bearing performance of the structure. Repeated adjustments and repairs are required, impacting construction efficiency and quality control. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides an embankment protection and reinforcement device that can effectively overcome the deformation of the reinforcement structure caused by the flow of concrete during pouring, thereby improving the quality and construction efficiency of the reinforcement device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An embankment protection and reinforcement device includes: Multiple precast frame units are arranged within the embankment along the length of the road; Anchor bolts used to anchor the precast frame unit into the embankment; Connecting components that connect adjacent precast frame units; The precast frame unit is formed by a top beam, a bottom beam, and a pair of side beams to form a frame structure; a precast support frame is integrally formed inside the precast frame unit, the precast support frame includes a main frame extending vertically and connected to the top beam and the bottom beam at both ends, and multiple support frames that connect the main frame to the side beams on both sides.

[0006] This application provides a road embankment protection and reinforcement device, which mainly includes multiple precast frame units set in the road embankment along the length of the road, and each precast frame unit has an integrally formed precast support frame.

[0007] Specifically, each precast frame unit includes a top beam, a bottom beam, and two side beams. The top beam and bottom beam are positioned opposite each other, and the two side beams are connected to the two ends of the top beam and bottom beam, respectively, forming a rectangular or approximately rectangular frame structure. In addition, the precast support frame includes a vertically arranged main frame connecting the top beam and bottom beam, as well as multiple support frames distributed on both sides of the main frame. One end of each support frame is connected to the side beam on the corresponding side, and the other end is connected to the main frame, thereby forming a spatial stiffening truss structure within the frame, which significantly enhances the overall rigidity and deformation resistance, and can effectively reinforce and protect the embankment slope.

[0008] In practice, construction begins at the prefabrication site according to the design dimensions: precast frame units and support frames are integrally cast in flat molds using concrete; after curing to the specified strength, the precast components are transported to the construction site using transport equipment, and precisely placed into the pre-excavated and leveled embankment using hoisting machinery. Subsequently, anchor bolts are drilled into the soil and rock of the foundation pit sidewall from the predetermined position of the precast frame unit, firmly anchoring the entire precast frame unit inside the slope. Adjacent precast frame units are laterally connected by connecting components, such as bolted connectors, pin joints, or welded steel plates, to enhance the continuity and coordinated load-bearing performance of the overall structure.

[0009] This invention involves installing precast frame units and integrally formed precast support frames within the foundation pit of an embankment slope. Anchor bolts are used to anchor the frame units to the slope's soil and rock mass. Connecting components are employed to achieve lateral connections between adjacent units, forming a stable overall support structure. Compared to traditional on-site cast-in-place slope protection methods, this structure effectively inhibits the sliding flow of concrete during steep slope pouring, prevents structural deformation, and significantly improves the forming quality and construction efficiency of the reinforced structure.

[0010] Preferably, the top surface of the top beam and the bottom beam are respectively provided with a first drainage groove and a second drainage groove along their length direction.

[0011] The first and second drainage ditches effectively guide and quickly drain accumulated water from the embankment slope. The first drainage ditch, located on the top beam, intercepts water from above, preventing rainwater from directly eroding the embankment surface. The second drainage ditch, located on the bottom beam, collects and diverts rainwater flowing down from above, preventing water accumulation at the slope base or erosion at the slope toe. Working together, they form a "top interception, bottom drainage" drainage system, significantly reducing surface water erosion of the slope, lowering soil moisture content, and enhancing soil shear strength, thereby effectively improving the overall stability and disaster resistance of the embankment slope.

[0012] Preferably, the top surface of the main frame is provided with a first drainage groove, and the top surface of the support frame is provided with a second drainage groove; the first drainage groove is connected to the first drainage ditch and the second drainage ditch, and the second drainage groove is connected to the first drainage ditch.

[0013] By setting first and second drainage ditches on the top surfaces of the main and auxiliary frames of the precast support structure, and connecting them to the first and second drainage ditches on the precast frame unit in multiple stages, a complete drainage path is formed. Rainwater can flow into the first drainage ditches via either the first or second drainage ditches, and then be uniformly guided to the second drainage ditches at the bottom, achieving rapid and orderly discharge. This design effectively avoids rainwater retention or accumulation on the structural surface, significantly improves overall drainage efficiency, reduces the risk of water seeping into the slope soil, and further enhances the stability and durability of the embankment.

[0014] Preferably, the connection point of each of the support frames and the side beams is located above its connection point with the main frame.

[0015] The support frame is arranged diagonally upwards on both sides of the main frame, and the second drainage ditch opened on its top surface naturally forms an inclined water guiding surface, which is conducive to rainwater flowing quickly along the ditch towards the main frame, avoiding water accumulation and stagnation. Together with the first drainage ditch and the frame drainage ditch, it forms an efficient, gravity-flow drainage network.

[0016] Preferably, the width of the first drainage groove is greater than the width of the second drainage groove.

[0017] Rainwater collected by multiple secondary drainage channels eventually flows into the primary drainage channel, enabling it to bear a greater water collection load. By increasing the cross-sectional area of ​​the main channel, drainage capacity and flow efficiency are effectively improved, avoiding water accumulation or overflow caused by poor drainage downstream due to large upstream water volume. At the same time, the risk of silt blockage is reduced, and water flow resistance is decreased.

[0018] Preferably, each of the side beams has a corresponding mounting groove on its outer side for installing the connecting assembly. The connecting assembly includes a connecting plate that is laterally embedded in two adjacent mounting grooves and a plurality of fastening bolts for fixing. The depth of the mounting groove is greater than the thickness of the connecting plate.

[0019] By setting an installation groove on the outside of the side beam, and making the depth of the installation groove greater than the thickness of the connecting plate, the outer surface of the connecting plate after embedding is lower than the surface of the side beam, forming a concave connection structure. After the adjacent precast frame units are laterally connected by the connecting plate and fastening bolts, the installation groove can be completely sealed and filled with cast-in-place concrete, encasing the connecting plate and bolt joint inside the concrete, which can further effectively enhance the connection strength.

[0020] Preferably, a plant planting board is also provided in the area enclosed by the precast frame unit and the precast support frame, and the top surface of the plant planting board is lower than the bottom surface of the precast support frame.

[0021] The top surface of the planting board is lower than the bottom surface of the pre-cast support frame, which allows it to be stably installed in the planting area. It also leaves a certain gap to provide growth space for the plants. As the vegetation develops, its root system can further anchor the surface soil and improve the shallow stability of the slope.

[0022] Preferably, each of the precast frame units is also provided with multiple connecting ropes, which are arranged in an alternating pattern below the plant planting board.

[0023] The connecting ropes work in conjunction with the precast frame units to effectively enhance the overall structural strength of the frame. After backfilling and planting vegetation, the soil gradually covers the multiple interlaced connecting ropes, and the plant roots extend downwards and intertwine between the soil and the ropes, facilitating the binding of the soil within the frame into a single unit and improving the overall erosion resistance.

[0024] In summary, this utility model has the following beneficial effects: 1. By setting up precast frame units and precast support frames integrally formed with them, the embankment slope can be effectively reinforced. Since both are precast structures, they can effectively overcome the problem of deformation caused by the flow of concrete during embankment slope pouring, and at the same time effectively improve construction efficiency.

[0025] 2. The top beam of the precast frame unit has a first drainage ditch, and the bottom beam has a second drainage ditch. Both are connected to the diversion ditch, which effectively prevents rainwater from lingering or accumulating on the structural surface, significantly improves the overall drainage efficiency, reduces the risk of water seeping into the slope soil, and further enhances the stability and durability of the embankment.

[0026] 3. The connecting ropes work in conjunction with the precast frame units to effectively enhance the overall structural strength of the frame. Attached Figure Description

Detailed Implementation

[0029] To make the technical means, inventive features, objectives, and effects of this utility model readily understandable, the present utility model is further described below in conjunction with specific illustrations. However, this utility model is not limited to the following embodiments.

[0030] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the conditions under which this utility model can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0031] like Figures 1 to 2 As shown, this application provides an embankment protection and reinforcement device for structural reinforcement and ecological protection of soil or soft rock embankment slopes. The device mainly includes multiple precast frame units 2 arranged along the length of the road within the embankment 1. Each precast frame unit 2 has an integrally formed precast support frame 5, which is anchored to the soil and rock mass of the embankment 1 by anchor bolts 3. Lateral connections between adjacent precast frame units 2 are achieved through connecting components 4, thereby forming a continuous, synergistically stressed overall protective structure.

[0032] Specifically, to ensure effective reinforcement and protection of the embankment slope, each precast frame unit 2 includes a top beam 21, a bottom beam 22, and two side beams 23. The top beam 21 and the bottom beam 22 are positioned opposite each other, and the two side beams 23 are connected to the two ends of the top beam 21 and the bottom beam 22, respectively, forming a rectangular or approximately rectangular frame structure. In addition, the precast support frame 5 is integrally formed with the precast frame unit 2 during the concrete pouring process, forming an integral reinforced concrete structure. The precast support frame 5 includes a vertically arranged main frame 51, the upper and lower ends of which are firmly connected to the top beam 21 and the bottom beam 22, respectively, constituting the main load-bearing components. Multiple support frames 52 are symmetrically arranged on both sides of the main frame 51. One end of each support frame 52 is connected to the side of the main frame 51, and the other end is connected to the side beam 23 on the corresponding side, thereby forming a spatial three-dimensional stiffened truss structure inside the frame.

[0033] To further improve the drainage performance of the slope and prevent surface erosion caused by rainwater scouring, a first drainage ditch 211 is provided on the top surface of the top beam 21 along its length to intercept surface runoff from above the slope top and prevent water from directly scouring the embankment slope. A second drainage ditch 221 is provided on the top surface of the bottom beam 22 along its length to collect rainwater flowing down from the upper slope and guide it in an orderly manner to the slope toe drainage system or water collection facility to prevent water accumulation from eroding the slope toe or softening the foundation.

[0034] Furthermore, a first drainage ditch 511 is provided on the top surface of the main frame 51 of the precast support frame 5, and a second drainage ditch 521 is provided on the top surface of each support frame 52. Both the first drainage ditch 511 and the second drainage ditch 521 extend along the length of their respective frames and are interconnected with the first drainage ditch 211 and the second drainage ditch 221 in multiple stages, forming a complete gravity-flow drainage network. Specifically, rainwater from the slope can flow into the first drainage ditch 511 through the first drainage ditch 211, or flow into the first drainage ditch 511 through the second drainage ditch 521, and then be uniformly guided by the first drainage ditch 511 to the second drainage ditch 221, ultimately being discharged outside the structure, achieving graded interception, centralized diversion, and rapid discharge of rainwater.

[0035] To avoid localized water accumulation or overflow due to insufficient downstream drainage capacity caused by concentrated upstream water flow, the cross-sectional width of the first diversion ditch 511 is greater than the width of the second diversion ditch 521, thereby enhancing the water-carrying capacity of the main channel. Preferably, the width of the first diversion ditch 511 is 1.5 to 2.5 times the width of the second diversion ditch 521, and the specific value can be determined based on the design rainfall return period and catchment area. In this embodiment, the support frame 52 extends obliquely upward from the main frame 51 to both sides. This oblique arrangement allows the second diversion ditch 521 on the top surface of the support frame 52 to naturally form an oblique water-guiding surface, which facilitates the rapid flow of rainwater along the ditch towards the main frame 51 under the action of gravity, preventing rainwater stagnation or backflow, and further improving drainage efficiency.

[0036] Preferably, such as Figure 1 As shown, a plant planting board 6 is also provided in the area enclosed by the precast frame unit 2 and the precast support frame. The top surface of the plant planting board 6 is lower than the bottom surface of the precast support frame 5, which allows it to be stably installed in the planting area. A certain gap is left to provide growth space for the plants. As the vegetation develops, its root system can further anchor the surface soil and improve the shallow stability of the slope.

[0037] To further improve the overall structural strength of the frame, such as Figure 3 and Figure 4 As shown, each precast frame unit is also equipped with multiple connecting ropes 7, which are staggered below the plant planting board 6. The connecting ropes 7 work in conjunction with the precast frame unit 2 to effectively enhance the overall structural strength of the frame. After backfilling the soil and planting vegetation, the soil gradually covers the multiple staggered connecting ropes 7, and the plant roots extend downwards and intertwine between the soil and the ropes, making it easier to bind the soil within the frame into a whole and improve the overall erosion resistance.

[0038] In practice, construction begins at the prefabrication site according to the design dimensions: precast frame units 2 and precast support frames 5 are integrally cast in a flat mold using concrete; after curing to the specified strength, the precast components are transported to the construction site using transportation equipment, and precisely placed into the pre-excavated and leveled embankment 1 using hoisting machinery. Subsequently, anchor bolts 3 are drilled into the soil and rock of the pit sidewall from the predetermined position of the precast frame unit 2, firmly anchoring the entire precast frame unit 2 to the inside of the slope. Adjacent precast frame units 2 are laterally connected by connecting components 4, which can be bolted connectors, pin joints, or welded steel plates, etc., to enhance the continuity and coordinated load-bearing performance of the overall structure.

[0039] like Figure 3As shown, the connecting component 4 in this embodiment includes a connecting plate 41 and fastening bolts 42. Specifically, an installation groove 231 is provided on the outer side of each side beam 23. Each connecting plate 41 is embedded into the installation groove 231 of the adjacent side beams 23 of the left and right frames, and then locked by the fastening bolts 42 to achieve a stable connection between the two adjacent frame units. To enhance the connection strength, the depth of the installation groove is greater than the thickness of the connecting plate 41, so that the outer surface of the connecting plate 41 is lower than the surface of the side beam after it is embedded, forming a concave connection structure. After the lateral connection is completed, the installation groove 231 can be completely sealed and filled with cast-in-place concrete, encasing the connecting plate 41 and the bolt joint inside the concrete, thereby providing higher connection strength and durability.
