Description

Technical Field

[0001] This utility model relates to the field of geogrid technology, specifically a novel geogrid combined with anchor bolts. Background Technology

[0002] Geogrid is a major geosynthetic material. Compared with other geosynthetic materials, it has unique properties and functions. It plays a role in reinforcement and support in soil engineering. Geogrids are divided into four main categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids, and polyester warp-knitted geogrids.

[0003] In the prior art, a patent application with application number CN202222643737.8 discloses a novel steel-plastic geogrid with convex nodes. The geogrid body includes four grid ribs arranged in a cross shape. convex nodes are provided at the nodes of the grid ribs to improve load-bearing capacity. Each convex node includes an upper and lower embedded portion and a supporting portion. The embedded portion includes square-shaped protrusions arranged in a stepped pattern, with a groove at the upper end of each protrusion containing a reinforcing member. The supporting portion includes a supporting plate adapted to the protrusions and also arranged in a stepped pattern. A triangular abutment block is provided on the end face of the supporting plate abutting against the grid ribs. A pad is provided at the lower end of the supporting plate. A wavy limiting strip, welded to the geogrid, is provided at the lower end of each grid rib. This invention effectively increases the strength at the nodes of the geogrid, improves its load-bearing capacity, enhances its interlocking with soil and rock, and meets application requirements.

[0004] However, in the existing technology of novel steel-plastic geogrids with convex nodes, the installation of the geogrid ribs and the convex nodes is achieved by the friction between the clamping block and the geogrid ribs. However, geogrids are used outdoors for a long time, and under the effects of thermal expansion and contraction and rain and snow, the friction between the clamping block and the geogrid ribs will decrease sharply, which will lead to the risk of the geogrid ribs detaching from the convex nodes. Utility Model Content

[0005] The purpose of this invention is to provide a novel geogrid that can be combined with anchor bolts to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel geogrid combined with anchor rods, comprising: anchor rods and geogrid ribs, with an anchor head provided on the surface of the anchor rod, characterized in that: a bearing plate is fixed to the top of the anchor head, a top plate is provided above the bearing plate by bolts, geogrid ribs are provided between the bearing plate and the top plate, a bearing plate pin insertion hole is provided on the surface of the bearing plate, a top plate pin insertion hole is provided on the surface of the top plate, one end of a pin is rotatably inserted into the top plate pin insertion hole, and the other end of the pin is rotatably inserted into the bearing plate pin insertion hole, and a drilled hole is provided on the surface of the geogrid ribs, with the rod of the pin rotatably inserted into the drilled hole.

[0007] Preferably, the pin has a circular rod structure, with a pointed cone at the bottom end and threads on the rod.

[0008] Preferably, a threaded sleeve is fixed to the top of the top plate. The threaded sleeve has an annular cylindrical structure. The top of the pin is rotatably connected in the threaded sleeve. The inner wall of the threaded sleeve is threaded, and the thread of the threaded sleeve matches the thread of the pin.

The anchor rod is inserted into the round hole. A pressing plate is provided on the surface of the bearing plate and the top plate at the end that is close to each other, and one end of the pressing plate abuts against the surface of the grid rib.

[0011] Preferably, a leakage hole is provided on the inner wall of the bottom end of the groove of the bearing plate pin insertion hole, and the leakage hole is a circular hole structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention proposes a novel geogrid combined with anchor rods. The geogrid ribs are sandwiched between a bearing plate and a top plate, with clamping plates fixed to the bearing and top plates. These plates secure the geogrid ribs through friction.

Furthermore, this novel geogrid combined with anchor rods replaces the protrusions in existing technologies, allowing for deeper embedding into the soil and rock, resulting in a more secure installation.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1 to 4This utility model provides a technical solution: a novel geogrid combined with anchor rods, comprising: anchor rods 1 and geogrid ribs 2. An anchor head 3 is provided on the surface of the anchor rod 1, and a bearing plate 4 is fixed to the top of the anchor head 3. A top plate 5 is provided above the bearing plate 4 by bolts. Geogrid ribs 2 are provided between the bearing plate 4 and the top plate 5. A bearing plate pin insertion hole 8 is provided on the surface of the bearing plate 4, and a top plate pin insertion hole 7 is provided on the surface of the top plate 5. One end of a pin 9 is rotatably inserted into the top plate pin insertion hole 7, and the other end of the pin 9 is rotatably inserted into the bearing plate pin insertion hole 8. A drill hole 10 is provided on the surface of the geogrid ribs 2, and the rod of the pin 9 is... The anchor rod 1 is inserted into the drill hole 10. Both the bearing plate 4 and the top plate 5 are square plate structures, and a round hole is opened in the middle of both the bearing plate 4 and the top plate 5. The anchor rod 1 is inserted into the round hole. A clamping plate 13 is provided on the surface of the bearing plate 4 and the top plate 5 at the end that are close to each other. One end of the clamping plate 13 abuts against the surface of the grid rib 2. The pin 9 is a round rod structure with a pointed cone at the bottom end. The rod of the pin 9 is threaded. A threaded sleeve 6 is fixed at the top of the top plate 5. The threaded sleeve 6 is an annular cylindrical structure. The top of the pin 9 is rotatably connected to the threaded sleeve 6. The inner wall of the threaded sleeve 6 is threaded, and the thread of the threaded sleeve 6 matches the thread of the pin 9.

[0021] When installing this new type of geogrid combined with anchor rods, the bottom ends of each set of anchor rods 1 are first driven into the soil and rock, and the anchor heads 3 are installed on the anchor rods 1. After completing the above work, the geogrid ribs 2 are laid between two adjacent sets of anchor rods 1. During the laying, the top plate 5 is first installed on top of the bearing plate 4 with bolts, but the bolts are not tightened, so that there is a large gap between the bearing plate 4 and the top plate 5. Then, the ends of the geogrid ribs 2 are inserted between the bearing plate 4 and the top plate 5. At this time, the pins 9 are fully retracted into the threaded sleeves 6, and the drilling 10 has not yet been completed. Formed on the surface of the grille rib 2, after the end of the grille rib 2 is inserted, the bolts used to install the support plate 4 are tightened completely. At this time, the pressure plate 13 on the surface of the support plate 4 and the top plate 5 generates friction on the grille rib 2, pre-fixing the grille rib 2. Finally, the screwdriver is inserted into the screw sleeve 6 from the top and screwed into the pin 9 through the slot of the screwdriver and the pin 9. After being screwed, the pin 9 moves downward under the engagement of the threads of the pin 9 and the screw sleeve 6, so that the bottom end of the pin 9 enters the top plate pin insertion. Drill holes 10 are drilled into the surface of the plastic geogrid ribs 2, and then pins 9 continue to move downwards and insert into the pin insertion holes 8 of the bearing plate. In this new type of geogrid combined with anchor rods, the geogrid ribs 2 are sandwiched between the bearing plate 4 and the top plate 5, and the bearing plate 4 and the top plate 5 are fixed with clamping plates 13, which can fix the geogrid ribs 2 by friction. At the same time, the surface of the top plate 5 is provided with top plate pin insertion holes 7, the surface of the bearing plate 4 is provided with bearing plate pin insertion holes 8, and the surface of the geogrid ribs 2 is provided with drill holes 10. One end of the pin 9 is inserted into the pin insertion hole 7 in the top plate and the other end is inserted into the pin insertion hole 8 in the bearing plate. The rod of the pin 9 is inserted into the drill hole 10. Even if the friction between the clamping plate 13 and the grid rib 2 decreases too much, the pin 9 still applies radial force to the inner wall of the drill hole 10, thereby preventing the grid rib 2 from detaching from the surface of the anchor rod 1. In addition, the new geogrid combined with the anchor rod replaces the protrusion in the prior art with the anchor rod 1, and the embedment distance in the rock and soil is deeper, making the installation of the new geogrid combined with the anchor rod more secure.

[0022] Example 2: Based on Example 1, in order to prevent the pin 9 from moving upward on its own, a spring plate 11 is fixed to the top of the inner ring of the threaded sleeve 6. The spring plate 11 has a circular annular plate structure. A spring 12 is provided in the threaded sleeve 6. The top of the spring 12 abuts against the bottom surface of the spring plate 11, and the bottom of the spring 12 abuts against the top surface of the pin 9.

[0023] A spring plate 11 is fixed to the top of the inner wall of the threaded sleeve 6. One end of the spring 12 abuts against the surface of the spring plate 11 and the other end abuts against the surface of the pin 9, thereby pressing the threaded connection between the pin 9 and the threaded sleeve 6, and generating a large frictional force between the threads of the pin 9 and the threaded sleeve 6, preventing the pin 9 from rotating on its own under the vibration caused by the surrounding instruments, causing the pin 9 to move upward and fall out of the pin insertion hole 8 and the drill hole 10 of the bearing plate.

[0024] Example 3: Based on Example 2, in order to quickly drain the rainwater in the pin insertion hole 8 of the bearing plate, a drain hole 14 is provided on the inner wall of the bottom groove of the pin insertion hole 8 of the bearing plate. The drain hole 14 has a circular hole structure.

[0025] A drain hole 14 is opened at the bottom of the inner wall of the groove of the bearing plate pin insertion hole 8. When there is rainwater inside the top plate pin insertion hole 7, the bearing plate pin insertion hole 8 and the drill hole 10, or between the grid rib 2 and the pressing plate 13, the rainwater can flow into the bearing plate pin insertion hole 8 and then quickly flow out from the drain hole 14, thereby accelerating the drying speed of the surface of each component after rain and quickly restoring the friction between the pressing plate 13 and the grid rib 2.

[0026] In practical use, when installing this new type of geogrid combined with anchor rods, the bottom ends of each set of anchor rods 1 are first driven into the soil and rock, and the anchor heads 3 are installed on the anchor rods 1. After completing the above work, the geogrid ribs 2 are laid between two adjacent sets of anchor rods 1. During the laying, the top plate 5 is first installed on top of the bearing plate 4 with bolts, but the bolts are not tightened, so that there is a large gap between the bearing plate 4 and the top plate 5. At this time, the ends of the geogrid ribs 2 are inserted between the bearing plate 4 and the top plate 5. At this time, the pins 9 are fully retracted into the threaded sleeves 6, and the drill holes 10 have not yet been formed on the surface of the geogrid ribs 2. After the ends of the geogrid ribs 2 are inserted, the bearing plates are installed. The bolts on the carrier plate 4 are fully tightened. At this time, the clamping plates 13 on the surfaces of the carrier plate 4 and the top plate 5 generate friction on the grid ribs 2, pre-fixing the grid ribs 2. Finally, a screwdriver is inserted into the threaded sleeve 6 from the top and screwed into the pin 9 through the slot at the top of the pin 9. After being screwed, the pin 9 moves downward under the engagement of the threads of the pin 9 and the threaded sleeve 6, so that the bottom end of the pin 9 enters the pin insertion hole 7 in the top plate and continues to drill a hole 10 on the surface of the plastic grid ribs 2. Then, the pin 9 continues to move downward and inserts into the pin insertion hole 8 in the carrier plate. This new type of geotechnical system combined with anchor rods The grid, with grid ribs 2 sandwiched between a support plate 4 and a top plate 5, has clamping plates 13 fixed to the support plate 4 and top plate 5. These plates can be secured to the grid ribs 2 through friction. The top plate 5 has a top plate pin insertion hole 7, and the support plate 4 has a support plate pin insertion hole 8. The grid ribs 2 have drilled holes 10. One end of a pin 9 is inserted into the top plate pin insertion hole 7, and the other end is inserted into the support plate pin insertion hole 8. The rod of the pin 9 is inserted into the drilled hole 10. Even if the friction between the clamping plate 13 and the grid ribs 2 decreases significantly, the pin 9 still applies radial force to the inner wall of the drilled hole 10, thus preventing the grid ribs 2 from slipping off the anchor. The surface of rod 1 is detached. In addition, the new geogrid combined with the anchor rod replaces the protrusion in the prior art with the anchor rod 1, and the embedment distance in the rock and soil is deeper, making the installation of the new geogrid combined with the anchor rod more secure. A spring plate 11 is fixed to the top of the inner wall of the threaded sleeve 6. One end of the spring 12 abuts against the surface of the spring plate 11 and the other end abuts against the surface of the pin 9, so that the threaded connection between the pin 9 and the threaded sleeve 6 is pressed, so that a large frictional force is generated between the threads of the pin 9 and the threaded sleeve 6, preventing the pin 9 from rotating on its own under the vibration caused by the surrounding machinery, causing the pin 9 to move upward and fall out of the pin insertion hole 8 and the drill hole 10 of the bearing plate.A drain hole 14 is provided at the bottom of the inner wall of the groove in the support plate pin insertion hole 8. When rainwater is present inside the top plate pin insertion hole 7, the support plate pin insertion hole 8, and the drilled hole 10, or between the grid rib 2 and the clamping plate 13, the rainwater can flow into the support plate pin insertion hole 8 and then quickly flow out through the drain hole 14. This accelerates the drying speed of the surfaces of various components after rain, allowing the friction between the clamping plate 13 and the grid rib 2 to be quickly restored.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
