Description

Instruction Manual 1 A Land Title Confirmation Boundary Marker Anti-Displacement Fixing Device Technical Field This invention provides a land title confirmation boundary marker anti-displacement fixing device, belonging to the field of land surveying and management technology. Background Art Land title confirmation is a fundamental task for maintaining national land ownership and protecting the legitimate rights and interests of land rights holders. In the process of land title confirmation, setting clear, stable, and durable boundary markers, commonly known as "boundary stakes" or "boundary markers," is a crucial step. These markers are physical evidence confirming the four boundaries of the land, and the accuracy and stability of their positions directly affect the seriousness and legal validity of land management. According to the analysis of existing technologies, traditional boundary markers currently used in field surveys and land management typically employ simple precast concrete piles, stone boundary markers, or metal poles directly driven into or buried underground. While meeting normal usage needs, these traditional boundary markers have several significant drawbacks: poor stability and susceptibility to displacement. Traditional boundary markers often use simple precast concrete or stone piles directly buried in the ground. This method has limited burial depth and weak bonding with the soil. When faced with external forces such as farming activities, construction projects, or human impacts, they often cannot effectively resist these sudden lateral impacts and are prone to tilting or shifting. Such positional changes can lead to land ownership disputes. Therefore, this invention provides a land ownership boundary marker anti-displacement fixing device. The technical problem this invention solves is: poor stability, susceptibility to displacement, and susceptibility to tilting or shifting when subjected to external impacts, which can lead to land ownership disputes. HK 30134888 A Specification 2 To solve the technical problem, the technical solution provided by this invention is: a land ownership boundary marker anti-displacement fixing device, including a base, and further including: a marker component, located above ground, including a marker plate for marking land ownership boundary information; an anti-displacement anchoring component, located below ground, including: a support block that fits against the middle part of the bottom of the base, wherein the top and bottom ends of the side wall of the support block are provided with cross plates buried below ground, and the four sides of the cross plates are provided with inserting cones located outside the base; a central anchor rod penetrating the center of the base and the support block for insertion into deep soil; and a pair of locking nuts for locking the central anchor rod and the support block onto the base. Further, the central anchor rod includes a rod body, the upper part of which is provided with threads matching the locking nuts, the lower part of which is provided with a spiral blade for easy drilling into the soil, and the bottom end of which is provided with a soil-inserting tip. Further, the outer wall of the soil-inserting tip is provided with several anchoring wings around its circumference. Furthermore, the length of the central anchor rod is 0.45M-0.65M, and the length of the insert cone is 0.15M-0.25M.Furthermore, the marking assembly also includes a support column fixedly mounted on the top of the base. The marking plate is fixedly connected to the upper end of the support column by a pair of clamps. The bottom of the support column is provided with a flange, which is fixedly mounted on the top of the base by high-strength bolts. The bottom of the support column is provided with a concave hole that communicates with the center of the flange. Furthermore, both the base and the support block are provided with through holes for the center anchor rod to pass through. The pair of locking nuts includes an upper nut that fits against the top of the base and is placed inside the concave hole, and a lower nut that fits against the bottom of the support block. Furthermore, the top of each of the four sides of the cross plate, away from the support block, is provided with through holes for the insertion cone to pass through. A connecting plate is provided between the adjacent sidewalls of the cross plate, located on the outside of the support block. The beneficial effects of this invention are as follows: This invention uniquely combines deep central anchoring with shallow perimeter anchoring, achieving a three-dimensional anchoring system that combines deep and shallow anchoring, and coordinates central and perimeter anchoring. The central anchor penetrates deep into the stable soil layer, providing strong resistance to vertical pull-out force and rotation. Simultaneously, the underground frame structure composed of support blocks, cross plates, and four cones greatly expands the support area and volume of the device underground, effectively dispersing and resisting external forces such as horizontal thrust and impact from all directions on the ground. This significantly reduces the risk of the central anchor being tilted or loosened by impact, thus helping to prevent the marker from tilting or shifting laterally, resulting in greater stability and less likelihood of displacement, thereby avoiding unnecessary land disputes.

It should be understood that the embodiments described herein are merely illustrative of this application and are not intended to limit this application. As shown in Figures 1, 4, and 5: This invention provides a land ownership boundary marker anti-displacement fixing device, including a base 1 and a marker component 2 located above the ground. The marker component 2 includes a marker plate 4 for clearly marking key information such as land ownership and boundary point number. The marker component 2 also includes a support column 3 fixedly installed on the top of the base 1. The marker plate 4 is fixedly connected to the upper end of the support column 3 by a pair of clamps 15, which facilitates the installation and replacement of the marker plate. The bottom of the support column 3 is provided with a flange 16, which is fixedly installed on the top of the base 1 by high-strength bolts. The bottom of the support column 3 is provided with an indented hole 17 that communicates with the center of the flange 16 to avoid interfering with the upper end of the central anchor rod 6.HK 30134888 A Instruction Manual 5 As shown in Figures 2, 3, 5, and 6 of the instruction manual, it also includes an anti-displacement anchoring assembly 5, located below ground level. This assembly includes a support block 8 that fits into the middle portion of the bottom of the base 1. The top and bottom ends of the sidewalls of the support block 8 are each provided with a cross plate 9 embedded below ground level. Each of the four sides of the cross plate 9 has a cone 10 located outside the base 1, providing strong lateral support and extending the anchoring range from directly below the base 1 to a wider area around it. A central anchor rod 6 penetrates the center of the base 1 and the support block 8 for insertion into deep soil. A pair of locking nuts 7 are used to lock the central anchor rod 6 and the support block 8 onto the base 1. The central anchor rod 6 includes a rod body 11, the upper part of which has threads matching the locking nuts 7, and the lower part of which has a helical blade 12. This not only facilitates drilling it into the soil during construction but also greatly increases its resistance to pull-out and rotation after installation. The bottom end is provided with a soil-inserting tip 13 to reduce the resistance to soil penetration. Several anchoring wings 14 are provided on the outer wall of the soil-inserting tip 13. After the central anchor rod 6 is screwed into the soil, the anchoring wings 14 can firmly grip the surrounding soil like a ship anchor, providing additional resistance to pull-out. The length of the central anchor rod 6 is 0.45M-0.65M, which is deep enough to penetrate the surface loose soil and reach a more solid soil layer. The length of the cone 10 is 0.15M-0.25M to provide effective lateral anchoring in shallow soil. As shown in Figures 5 and 6 of the instruction manual, both the base 1 and the support block 8 have through holes for the central anchor rod 6 to pass through. A pair of locking nuts 7 include an upper nut 19 that fits against the top of the base 1 and is placed inside the concave hole 17, and a lower nut 20 that fits against the bottom of the support block 8. The top of each of the four sides of the cross plate 9, away from the support block 8, has through holes for the insertion cone 10 to pass through. A connecting plate 18 is provided between the side walls of the cross plates 9 that are close to each other and is placed outside the support block 8. Specifically, the connecting plate 18 connects the upper and lower cross plates 9 to further resist twisting and deformation. The lower nut 20 and the upper nut 19 clamp the base 1 and the support block 8 together and fix them in place. At the same time, the central anchor rod 6 can be locked between the lower nut 20 and the upper nut 19. The installation position of the upper nut 19 can be ensured so as not to affect the installation of the support column 3.Installation and Working Principle of the Invention: HK 30134888 A Instruction Manual 6 During installation, firstly, dig a foundation pit of appropriate depth at the determined boundary point location. Place the central anchor rod 6 in the center of the foundation pit and use a tool (such as a torque wrench) to screw it into the deeper soil layer. During the screwing process, the spiral blade 12 allows the central anchor rod 6 to be easily drilled in, while the soil-inserting tip 13 is responsible for breaking the soil. According to the preferred scheme, the anchor rod length is 0.45 meters to 0.65 meters to ensure that it reaches the stable soil layer. Next, screw the lower nut 20 onto the rod body 11, insert the support block 8 into the rod body 11 and place it on top of the lower nut 20. Adjust the placement of the cross plate 9, and then pass the four inserting cones 10 through the through holes on the cross plate 9 and forcefully drive them into the soil around the foundation pit to form a strong lateral anchoring in the shallow soil layer. Subsequently, insert the base 1 through the rod body 11 and place it on the support block 8. Then tighten the installation nut 19 so that the lower nut 20 presses against the bottom of the support block 8 and the upper nut 19 presses against the top of the base 1, thereby firmly fixing the base 1 to the entire anti-displacement anchoring assembly 5; finally, backfill the soil and compact it, then fix the support column 3 to the base 1 with bolts through the flange 16, and fix the sign 4 to the upper end of the support column 3 through the clamp 15. When the installed device is subjected to external forces, such as lateral impact, the force is transmitted to the underground anti-displacement anchoring component 5 through the support column 3 and base 1. Since the underground frame structure formed by the cross plate 9 and the cone 10 covers a large area, this force is effectively dispersed into the surrounding soil, thus resisting lateral displacement and greatly reducing the risk of the central anchor rod 6 being tilted or loosened. This helps prevent the marker from tilting or shifting laterally. When the device is subjected to an upward pull-out force, the spiral blade 12 and anchoring wing 14 of the central anchor rod 6 generate a huge interlocking force with the deep soil. Combined with the longitudinal blocking of the cross plate 9 and the cone 10, this effectively prevents the device from being pulled out. This three-dimensional anchoring system, combining deep and shallow layers and coordinating the center and surrounding areas, has stronger stability and is less prone to displacement, thus avoiding unnecessary land disputes.
