Description

Technical Field

[0001] This utility model relates to the field of disaster prevention and mitigation technology in road engineering, and in particular to a slope protection structure for high embankment roads. Background Technology

[0002] The high-fill embankment slope protection structure is a comprehensive protection system for the slope stability of deep-fill road sections. It ensures the density of backfill soil and reduces settlement through layered compaction combined with dynamic tamping technology; it uses a herringbone-shaped water-blocking frame to intercept and divert surface water, preventing erosion; and it implements vegetation protection within the frame, forming a composite "plant + engineering" protection layer. This structure balances engineering strength and ecological restoration, effectively improving slope stability, reducing maintenance costs, and also considering landscape value.

[0003] In existing technologies, some high-fill embankment slope protection structures consist of layered compacted soil, a herringbone water-cutting frame, and a plant protection layer. The principle is to increase the soil density through layered compaction and dynamic tamping, guide surface water out of the frame to reduce erosion, and plant roots stabilize the soil and protect the slope. The three work together to enhance slope stability and take into account drainage, erosion resistance, and ecological restoration functions.

[0004] However, in the existing technology, the traditional cast-in-place protective structure with herringbone water interception frame for the slope protection structure of some high embankment has shortcomings in terms of construction efficiency, quality stability, maintenance cost and environmental protection. It has low construction efficiency and long construction period. Therefore, a new slope protection structure for high embankment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a slope protection structure for high embankments, aiming to improve the problem of low construction efficiency and impact on the ecological environment of slopes in some existing road engineering disaster prevention and mitigation technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high embankment slope protection structure, comprising a protection frame, a fixing plate fixedly connected to the outside of the protection frame, two protective plates fixedly connected to the outside of the fixing plate, the outside of the protection frame fixedly connected to the adjacent side of the protective plate, and two fixing steel bar holes opened inside the protection frame and the fixing plate. As a further description of the above technical solution: multiple folded plates are fixedly connected to the inner wall of the protective frame; As a further description of the above technical solution: the interior of the folded plate is provided with a groove, two grooves correspond to each other and the exteriors of the two folded plates are engaged; As a further description of the above technical solution: the folded plate has two fixing holes inside; As a further description of the above technical solution: a lower fixing block is provided at the bottom of the folded plate; As a further description of the above technical solution: the top of the lower fixing block is threadedly connected to the upper fixing block, and the interior of the upper fixing block is in contact with the exterior of the folded plate; As a further description of the above technical solution: the lower fixing block and the upper fixing block have three screw holes inside.

[0007] This utility model has the following beneficial effects: 1. In this utility model, through modular design, the protective frame, fixing plate, protective plate and folded plate components are prefabricated into standardized units. On-site, only bolt connection or rebar penetration is required through fixing rebar holes, fixing holes and screw holes. There is no need for complicated welding or pouring operations. Compared with the traditional cast-in-place concrete skeleton, its construction efficiency is improved, the construction period is shortened, and the risks of high-altitude operation and wet operation are reduced. It meets the needs of rapid construction of large-scale high-fill embankment slopes.

[0008] 2. In this utility model, the herringbone-shaped frame formed by the folded plate components realizes the integrated design of "engineering protection + plant soil stabilization". The vegetation root system and the frame structure work together. The root system penetrates deep into the soil to enhance the shear strength, and the frame intercepts and guides rainwater to reduce soil erosion. Compared with traditional hard protection, its vegetation coverage is increased, the ecological restoration cycle of the slope is shortened, and the slope temperature fluctuation and weathering erosion are effectively reduced, achieving a dual improvement in ecological benefits and engineering safety.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a slope protection structure for a high-fill embankment, comprising a protective frame 1, which is a rectangular steel structure frame. The protective frame 1 serves as the main supporting body of the overall skeleton, bearing the soil pressure on the slope and guiding the direction of water flow. Its rigidity and stability ensure the overall deformation resistance of the skeleton. A fixing plate 2, which is a trapezoidal steel plate, is fixedly connected to the external of the protective frame 1 by welding, forming a lateral support node of the skeleton, enhancing the structure's resistance to lateral slippage. Simultaneously, it serves as the contact interface between the skeleton and the slope soil, dispersing pressure to the deeper soil layers. Two protective plates 3 are fixedly connected to the external of the fixing plate 2. The surface of the protective plates 3 is provided with anti-slip textures, and they are connected to the pre-embedded parts of the fixing plate 2 by bolts, forming a slope protection layer. This design reduces the impact force of water flow. The external fixed connection of the protective frame 1 is on the side adjacent to the protective plates 3. Two fixing steel bar holes 4 are opened inside both the protective frame 1 and the fixing plate 2. The fixing steel bar holes 4 are used for pre-embedding... Embedded threaded steel bars are used to connect adjacent skeleton units, forming an overall load-bearing system, restricting the relative displacement between skeleton units, and enhancing the overall structural integrity. Multiple folded plates 5 are fixedly connected to the inner wall of the protective frame 1. The folded plates 5 are L-shaped bent steel plates, and their inner walls are welded and fixed to the protective frame 1. The bending structure increases the contact area with the soil, improves shear strength, and reduces local stress concentration. The folded plates 5 have grooves 7 inside. Two grooves 7 correspond to each other, and the two folded plates 5 are interlocked externally. The two folded plates 5 form a herringbone skeleton by interlocking. The skeleton template uses a standardized steel mold, which is prefabricated in the factory to ensure dimensional accuracy, reduce on-site construction errors, and improve the structural strength and appearance quality of the skeleton. The protective frame 1, the fixed plate 2, and the protective plate 3 are rigidly connected to form an overall load-bearing skeleton. The folded plates 5 are mechanically connected to the lower fixed block 8 and the upper fixed block 9 to enhance local stability. All components work together to achieve integrated slope protection and drainage.

[0013] Reference Figure 3 , Figure 4The folded plate 5 has two fixing holes 6 inside. The herringbone frame formed by the folded plate 5 is fixed to the slope protection through the fixing holes 6. A lower fixing block 8 is provided at the bottom of the folded plate 5, with anti-slip teeth on its bottom. The lower fixing block 8 is threadedly connected to the upper fixing block 9 to fix four folded plates 5 together, and also serves as a support base for the upper fixing block 9, transferring vertical loads to the deep soil. Multiple folded plates 5 are combined, with the gaps between the frames and the slope surface forming a three-dimensional vegetation net or planting bags. The top of the lower fixing block 8 is threadedly connected to the upper fixing block 9, which has a groove inside that matches the outer contour of the folded plate 5. The interior of the upper fixing block 9 and the folded plate 5... The upper fixing block 9 wraps around the top of the folded plate 5 through a slot, restricting its vertical displacement. At the same time, it forms a clamping structure with the lower fixing block 8, enhancing the frame's pull-out resistance. The lower fixing block 8 and the upper fixing block 9 have three screw holes 10 inside, which are distributed in a triangular pattern. The upper fixing block 9 and the lower fixing block 8 are fastened together by bolts. The triangularly distributed screw holes 10 form a stable force system, preventing structural failure caused by bolt loosening. The modular design allows the frame units to be prefabricated and assembled on site. The standardized design of the fixing holes 4, 6, and screw holes 10 simplifies the construction process, reduces on-site welding operations, and improves construction efficiency and quality.

[0014] Working principle: The protective frame 1 is connected to the protective plate 3 via the fixing plate 2 to form the main body of the embankment slope protection structure. The mechanical connection between modules is achieved by pre-embedding steel bars through the fixing steel bar holes 4, avoiding on-site casting. The inner wall of the main structure is equipped with folded plates 5. The grooves 7 of two identical folded plates 5 correspond to each other and the two identical folded plates 5 interlock with each other. The skeleton unit adopts a standardized design and is precisely formed by a fixed steel mold. The bottom of the four folded plates 5 is connected to the upper fixing block 9 by the lower fixing block 8 and fixed by the screw holes 10. While ensuring the overall stability of the skeleton, the gaps between the skeleton and the slope paving form a three-dimensional vegetation net or vegetation bags. Grass seeds, fertilizers and soil conditioners are mixed and sprayed onto the slope through a soil spraying machine to form a vegetation cover layer. The plant roots and the skeleton structure work together. The roots penetrate into the soil to enhance the shear strength, and the skeleton provides initial support. The two work together to improve the stability of the slope. At the same time, the vegetation cover reduces soil erosion and achieves the dual goals of ecological restoration and engineering protection.
