Description

Technical Field

[0001] This utility model relates to the field of geogrids, specifically a composite high-strength tensile geogrid. Background Technology

[0002] High-strength tensile geogrid is a type of composite material with high-strength steel wire or fiber as the core reinforcement and a polymer coating (such as polyethylene) on the outside. It forms a grid structure through special processes (such as ultrasonic welding and fusion welding technology), and has the characteristics of high tensile strength, corrosion resistance, creep resistance and convenient construction. It is widely used in the fields of civil engineering reinforcement, foundation reinforcement and slope protection.

[0003] Existing geogrids are prone to deformation when subjected to excessive pressure, which can lead to uneven distribution of internal stress and reduce their supporting capacity. When steel wires are used to connect and fix adjacent geogrids, uneven stress can cause the wires to break, resulting in a decrease in the load-bearing capacity of the geogrid.

[0004] Therefore, this utility model proposes a composite high-strength tensile geogrid to solve the above-mentioned problems. Utility Model Content

[0007] The long sleeve plate has an internal long groove that engages with the long card plate. The top center of the fixing block has a limiting groove, and the top of the long card plate has a groove.

Detailed Implementation

[0021] 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.

[0022] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a composite high-strength tensile geogrid, comprising: a geogrid body 1, a fixing block 2 installed at the center of the surface of the geogrid body 1, a set of symmetrically placed long clamping plates 3 installed on the surface of the geogrid body 1, a long sleeve plate 4 sleeved on the outer surface of the fixing block 2, a long groove 5 opened inside the long sleeve plate 4, the long groove 5 engaging with the long clamping plate 3, a limiting groove 6 opened at the center of the top of the fixing block 2, a groove 7 opened at the top of the long clamping plate 3, the two long clamping plates 3 abutting each other, the adjacent grooves 7 abutting each other and having the same size and shape as the limiting groove 6, and a fixing component 8 installed through the top of the long sleeve plate 4;

[0023] In use, the long sleeve plate 4 is conveniently positioned and placed at the center of the back of the geogrid body 1 by the fixing block 2. At the same time, the long sleeve plate 4 is fixed to the geogrid body 1 by the fixing component 8 passing through the long sleeve plate 4 and entering the interior of the limiting groove 6. The placement of the long sleeve plate 4 can enhance the compressive strength of the geogrid body 1 and prevent the geogrid body 1 from deforming. It is also convenient for the geogrid body 1 to be rolled up, stored, and transported. Meanwhile, the long clamping plate 3 on the side allows two adjacent geogrid bodies 1 to be attached together and locked by the long sleeve plate 4. The fixing component 8 moves to the interior of the groove 7 to splice and position the two adjacent geogrid bodies 1.

[0024] Example 2: Based on Example 1, a structure is provided with a fixed long sleeve plate 4 for positioning and splicing two adjacent geogrid bodies 1. The fixing component 8 includes a long rod 9, which moves through the interior of the long sleeve plate 4. A locking block 10 is installed at the bottom of the long rod 9, which moves within the limiting groove 6 and the recess 7. A pointing block 11 is installed at the outer end of the long rod 9. A limiting sleeve 12 is fixed to the side wall of the long sleeve plate 4.

[0025] In use, the long rod 9 in the fixing component 8 passes through the bottom locking block 10 into the limiting groove 6 or the recess 7. The structure of the limiting groove 6 and the recess 7 makes it easy to rotate the long rod 9 so that the locking block 10 can rotate inside the limiting groove 6. When the locking block 10 rotates to the opening and changes angle, the top of the locking block 10 is in contact with the top of the inner wall between the limiting groove 6 and the recess 7, so that the long rod 9 fixes the long sleeve plate 4 on the geogrid body 1. It can also be used to position and splice two adjacent geogrid bodies 1. The top of the long rod 9 can quickly identify the position of the locking block 10 after rotation through the pointing block 11, so as to prevent the long sleeve plate 4 from falling off due to incorrect rotation angle of the locking block 10.

[0026] Example 3: Based on Example 2, a structure is provided to clamp the adjacent spliced ​​geogrid bodies 1. A toothed plate 13 is movably installed inside the limiting sleeve 12. A clamping block 14 is installed at the outer end of the toothed plate 13. A gear 15 is installed in the center of the limiting sleeve 12. The teeth of the gear 15 mesh with the toothed plate 13. A rotating shaft 16 is installed in the center of the gear 15. A long rod 9 passes through the center of the rotating shaft 16. A slot 17 is opened on the side wall of the rotating shaft 16. A positioning block 18 is fixed on the outer surface of the long rod 9. The positioning block 18 engages with the slot 17. A placement groove 19 is opened on the top of the limiting sleeve 12. The shape of the placement groove 19 is consistent with the shape of the pointing block 11.

[0027] In use, when the long rod 9 drives the locking block 10 downward, the positioning block 18 on the outer surface of the long rod 9 moves downward into the slot 17 of the rotating shaft 16. By rotating the pointing block 11, the long rod 9 is rotated, and under the action of the positioning block 18, the long rod 9 and the rotating shaft 16 are connected. This also drives the gear 15 on the outer surface of the rotating shaft 16 to rotate. Through the meshing of the gear 15 and the toothed plate 13, the toothed plates 13 on both sides can move synchronously in opposite directions under the action of the limiting sleeve 12. This, in turn, drives the clamping blocks 14 on both sides to clamp the two adjacent... After the geogrid body 1 is clamped, the long rod 9 is moved downward to move the pointing block 11 into the placement groove 19 to fix the long rod 9 and prevent it from rotating. Through engineering calculations, the rotation angle of the gear 15 and the movement of the clamping block 14 driven by the toothed plate 13 are in a certain regularity. This makes it convenient for the clamping block 14 to clamp the adjacent geogrid body 1 tightly. The position of the rotating pointing block 11 is on the same vertical plane as the placement groove 19. It also ensures that the locking block 10 at the bottom of the long rod 9 does not coincide with the inlet of the limiting groove 6 and the groove 7.

[0028] In actual use, the long sleeve plate 4 is conveniently positioned and limited by the fixing block 2 at the center of the back of the geogrid body 1. Simultaneously, the long rod 9 in the fixing assembly 8 passes through the bottom locking block 10 and enters the limiting groove 6 or recess 7. The structure of the limiting groove 6 and recess 7 facilitates the rotation of the long rod 9, causing the locking block 10 to rotate within the limiting groove 6. When the locking block 10 rotates to the opening and changes angle, the top of the locking block 10 contacts the top of the inner wall between the limiting groove 6 and recess 7, thus fixing the long sleeve plate 4 to the geogrid body 1. It also allows for the positioning and splicing of two adjacent geogrid bodies 1. The long rod 9 drives the locking block 10 downwards. At this time, the positioning block 18 on the outer surface of the long rod 9 moves downward to the inside of the slot 17 of the rotating shaft 16. By rotating the pointing block 11, the long rod 9 is driven to rotate. Then, under the action of the positioning block 18, the long rod 9 and the rotating shaft 16 are connected, and the gear 15 on the outer surface of the rotating shaft 16 is driven to rotate. Through the meshing of the gear 15 and the toothed plate 13, the toothed plates 13 on both sides can move synchronously in opposite directions under the action of the limiting sleeve 12. Then, the clamping blocks 14 on both sides clamp the two adjacent geogrid bodies 1. After that, the long rod 9 continues to move downward so that the pointing block 11 moves into the inside of the placement slot 19 to fix the long rod 9 and prevent the long rod 9 from rotating.

[0029] 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.
