Fabricated slope protection soil fixing brick

Abstract

This utility model provides a prefabricated slope protection and soil stabilization brick, effectively solving the problems of existing structures being not simple and reliable enough, requiring individual adjustments before rain, and not meeting practical needs. The technical solution includes a hexagonal outer frame with a matching inner frame inside, the outer and inner frames fitting tightly together. Each outer wall of the outer frame has two radially arranged through holes, and a pin is inserted into one of the through holes on the same outer wall. The end of the pin away from the inner frame extends beyond the outer frame, while the end of the pin near the inner frame abuts against the outer wall of the inner frame, and a bevel is provided on the end of the pin near the inner frame. When the inner frame is vertically inserted into the cavity of the outer frame, the bevel pushes the pin outward. This utility model has an ingenious structure, achieving reliable assembly through a simple design. After assembly, it is firmly fixed to the ground, allowing water to quickly seep into the ground during rain without requiring additional adjustments, thus better meeting practical needs.

Description

Technical Field

[0001] This utility model relates to the field of slope protection engineering technology, and in particular to a prefabricated slope protection and soil stabilization brick. Background Technology

[0002] Currently, in the construction of water conservancy projects, slopes are frequently eroded by water flow or rainwater, making their soil susceptible to erosion and landslides. Therefore, slope protection structures are often used for prevention and protection. Patent document CN218990061U discloses a prefabricated construction slope protection method, which achieves slope protection through a prefabricated structure. However, its structure has obvious unreasonable aspects. For example, the solution requires springs and rotating rods. In practical applications, soil inevitably intrudes into the mechanism during slope protection, causing the rotating and sliding joints to jam, thus failing to achieve its claimed purpose. Furthermore, this structure requires manual intervention during rain to accelerate water infiltration, but it is difficult to adjust the paving stones one by one before rain, unnecessarily increasing labor and failing to meet practical needs.

[0003] To address the aforementioned issues, a prefabricated slope protection and soil stabilization brick is provided. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a prefabricated slope protection and soil stabilization brick, which effectively solves the problems that the existing structure is not simple and reliable enough, requires individual adjustment before rain, and does not meet actual needs.

[0005] The technical solution includes a hexagonal outer frame with a matching inner frame inside, and the outer and inner frames are tightly fitted together. Each outer side wall of the outer frame has two radially formed through holes, and a pin is inserted into one of the two through holes on the same outer side wall. The end of the pin away from the inner frame extends out of the outer frame, and the end of the pin near the inner frame is pressed against the outer side wall of the inner frame. A bevel is provided on the end of the pin near the inner frame. When the inner frame is inserted vertically downward into the cavity of the outer frame, the inner frame can push the pin outward through the bevel.

[0006] Furthermore, both the outer frame and the inner frame are provided with multiple vertically connected drainage holes, which are evenly distributed.

[0007] Furthermore, a wedge-shaped protrusion is provided on the outer surface of the inner frame.

[0008] Furthermore, the cross-section of the through hole is cross-shaped.

[0009] Furthermore, the outer surface of the pin is provided with a wedge-shaped protrusion.

[0010] This utility model has a clever structure that achieves reliable assembly through a simple design. After assembly, it is firmly fixed to the ground and can quickly allow water to seep into the ground during rainy days without the need for additional adjustments, making it more in line with practical needs.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 3 The present invention includes a hexagonal outer frame 1, and a matching inner frame 2 inside the outer frame 1, with the outer frame 1 and the inner frame 2 in close contact. Two through holes 3 are radially opened on each outer side wall of the outer frame 1, and a pin 4 is inserted into one of the two through holes 3 on the same outer side wall. The end of the pin 4 away from the inner frame 2 extends out of the outer frame 1, and the end of the pin 4 near the inner frame 2 is pressed against the outer side wall of the inner frame 2. An inclined surface is provided on the end of the pin 4 near the inner frame 2. When the inner frame 2 is vertically inserted into the cavity of the outer frame 1, the inner frame 2 can push the pin 4 outward through the inclined surface.

[0016] To enhance hydrophobicity, both the outer frame 1 and the inner frame 2 are provided with multiple vertically connected hydrophobic holes 5, which are evenly distributed.

[0017] To prevent the inner frame 2 from springing back upward, a wedge-shaped protrusion 6 is provided on the outer surface of the inner frame 2.

[0018] To prevent the pin 4 from rotating during the insertion of the inner frame 2 into the outer frame 1, and to increase the contact area between the pin 4 and the outer frame 1 and adjacent outer frames 1, the cross-section of the through hole 3 is cross-shaped.

[0019] To prevent the pin 4 from springing back and to enhance the connection reliability between the pin 4 and the adjacent outer frame 1, a wedge-shaped protrusion 6 is provided on the outer surface of the pin 4.

[0020] It is worth noting that qualified slope protection bricks should serve the purpose of soil stabilization and drainage. In this scheme, the polygonal outer frame 1 and the pins 4 on the side of the outer frame 1 enable the entire structure to be firmly connected with the adjacent slope protection bricks, thus ensuring a secure fit to the ground. The inner frame 2 has a hollow center. In rainy weather, rainwater can be quickly drained into the ground through the center of the inner frame 2 and multiple drainage holes 5. When the rainfall is too heavy, mud and sand fall into the inner frame 2 and drainage holes 5, which can also help to slow down soil erosion.

[0021] When using, such as Figure 3 As shown, multiple outer frames 1 are arranged closely on the ground. Then, each pin 4 is placed into a through hole 3 on the side wall of the outer frame 1. Finally, multiple inner frames 2 are pressed one by one into the cavity of the outer frame 1. When pressing the inner frames 2, the inner frames 2 press the pins 4 outwards through the beveled ends of the pins 4, causing one outer end of the pin 4 to insert into a through hole 3 on an adjacent outer frame 1, ultimately achieving the purpose of slope protection. The edges can be enclosed with retaining strips or cement strips to prevent the slope protection bricks from loosening.

[0022] This utility model has a clever structure that achieves reliable assembly through a simple design. After assembly, it is firmly fixed to the ground and can quickly allow water to seep into the ground during rainy days without the need for additional adjustments, making it more in line with practical needs.
