Description

Technical Field

[0001] This utility model relates to the field of geogrid technology, and specifically to a rivet structure for geogrids. Background Technology

[0002] Geogrids, as a very important geosynthetic material, have been widely used in geotechnical engineering in my country. Traditionally, geogrids are divided into two main categories: uniaxial geogrids and biaxial geogrids. Uniaxial geogrids are generally used for structural support, while biaxial geogrids are mainly used for foundation treatment and controlling uneven settlement. Triaxial geogrids, based on the original biaxial geogrid, have optimized its structural form, and their performance in foundation reinforcement is far superior to that of traditional biaxial geogrids. As a new type of geogrid, it has also been widely used in engineering projects in recent years due to its excellent engineering properties.

[0003] Traditionally, the fixing of three-dimensional geogrids in a stacked connection is mainly achieved by binding or tightening. However, the geogrid also needs to be fixed to the ground at the same time as binding or tightening to increase its strength. Currently, the binding and ground fixing of multiple geogrids in a stacked connection are carried out in two separate processes, which means that the stacked connection and ground fixing of the geogrid cannot be carried out simultaneously. Therefore, this utility model proposes a rivet structure for geogrids. Utility Model Content

[0004] The purpose of this invention is to propose a rivet structure for geogrids, which aims to solve the problem that geogrids cannot be simultaneously stacked and fixed to the ground.

[0005] This utility model provides a rivet structure for geogrids, including: The rivet has an insertion end and a clamping end. The insertion end passes through the geogrid mesh to be inserted into the soil, and the clamping end is pressed against the geogrid. A clamping element is provided on the pressing end and forms at least one groove with the rivet rod for clamping the connection point or grid line of the geogrid.

[0006] Preferably, there are multiple clips, which are arranged circumferentially on the pressing end so that the multiple clips and the outer wall of the rivet form multiple slots to clamp onto the geogrid connection point or grid line.

[0007] The card has an "L" shaped structure and a pointed tip at the bottom.

[0008] The card has reinforcing ribs.

[0009] Preferably, the horizontal cross-section of the rivet is a "T" shaped structure, and the rivet includes two insert plates, one of which is vertically connected to the middle of the other insert plate. The edges of the two insert plates form an equilateral triangle structure.

[0010] Preferably, the rivet has a herringbone structure, comprising three insert plates, each with one side simultaneously connected to the axis. The edges of the three insert plates form an equilateral triangle, with the insertion end located at the center of the rivet's axis.

[0011] Preferably, the rivet has a cross-shaped structure and includes four insert plates that are simultaneously connected to the axis on one side.

[0012] Preferably, the horizontal cross-section of the rivet is circular, and the insertion end is conical.

[0013] Preferably, the rivet includes multiple insert plates, which are evenly distributed and spaced apart along the circumference of the pressing end, so that the rivet forms a hollow slot along the axial direction for insertion into the connection point of the geogrid.

[0014] Preferably, the rivet and clamp are made of metal or hard plastic.

[0015] Compared with existing technologies, it has the following beneficial effects: This utility model provides a rivet rod with an insertion end and a clamping end, and a locking device on the rivet rod. The locking device and the rivet rod form at least one slot for clamping the connection point or grid line of the geogrid. This allows the geogrid to be stacked and fixed to the ground simultaneously when the rivet rod is inserted into the soil through the insertion end. The connection strength is high, which can effectively reduce the problem of slippage between the stacked geogrids. Attached Figure Description

[0019] To facilitate a better understanding of the structure, achievable functional features and advantages of the present utility model, the preferred embodiments of the present utility model are described in detail below with reference to the accompanying drawings as follows: Embodiment 1: As shown in Figures 1 to 14 , the present utility model provides a rivet structure for a geogrid, which specifically comprises: A rivet rod 1, which has an insertion end 101 and a pressing end 101. The insertion end 101 passes through the meshes of the geogrid 3 to insert the rivet rod 1 into the soil, so that the pressing end 102 is pressed against the geogrid 3; A clamping member 2, which is arranged on the pressing end 102, and forms at least one clamping groove 201 with the rivet rod 1 for clamping the connection point 301 or the mesh line of the geogrid 3.

[0020] Referring to Figures 5 to 10 , there are a plurality of clamping members 2, and the plurality of clamping members 2 are arranged on the pressing end 102 along the circumferential direction, so that the plurality of clamping grooves 201 formed by the plurality of clamping members 2 and the outer wall of the rivet rod 1 are clamped on the connection points 301 or the mesh lines of the geogrid 3.

[0021] The number of the clamping members 2 in the present utility model is 1 to 6. When there is one clamping member 2, the clamping member 2 and the outer wall of the rivet rod 1 form one clamping groove 201 to clamp the mesh line; when there are three clamping members 2, the three clamping members 2 and the outer wall of the rivet rod 1 form three clamping grooves 201 to clamp the three connection points 301 of the three-way geogrid 3.

[0022] See Figure 1 and Figure 5 The card 2 has an "L" shaped structure and a pointed tip at the bottom to facilitate insertion into the soil.

[0023] See Figure 5 The clip 2 is provided with reinforcing ribs to improve its strength, thereby improving the fixing strength of the rivet structure.

[0024] Furthermore, the rivet 1 and the clip 2 are made of metal or hard plastic.

[0025] The working principle of this utility model is as follows: The insertion end 101 of the rivet rod 1 is inserted into the soil through the mesh of the stacked geogrid 3, so that the outer contour of the rivet rod 1 fits the geogrid 3; when the rivet rod 1 is fully inserted into the soil, the pressing end 102 of the end of the rivet rod 1 presses against the grid line of the geogrid 3. During this process, the slot 201 on the adjusting clip 2 can be smoothly inserted into the connection point 301 or grid line of the geogrid 3 to realize the stacked connection of multiple geogrids 3 and the ground fixation.

[0026] Example 2: like Figure 8 As shown, the horizontal cross-section of the rivet 1 is a "T" shaped structure. The rivet 1 includes two insert plates 103, one of which is vertically connected to the middle of the other insert plate 103. The edges of the two insert plates 103 form an equilateral triangle structure, so as to fit into the triangular mesh of the triaxial geogrid 3.

[0027] In this embodiment, the lower ends of the two insert plates 103 of the "T"-shaped rivet 1 are cut in one direction to form the insertion end 101 of the right-angled triangular structure, so that the rivet 1 can be inserted into the soil along the mesh side of the geogrid 3, and the mesh holes of the geogrid 3 can be quickly limited.

[0028] In this embodiment, the two insert plates 103 are vertically connected to form an equilateral triangle structure that can effectively adapt to the triangular mesh of the three-dimensional geogrid 3. This allows the rivet 1 to be quickly abutted against and limited by the three corners of the triangular mesh when inserted into the geogrid 3. This prevents the geogrid 3 from slipping under the limitation of the rivet 1 in the "T"-shaped structure. At the same time, it can also provide stability to the geogrid 3 stacked connection, preventing relative slippage between the two geogrids 3 stacked at the ends, and improving the connection strength between the two geogrids 3.

[0029] As an alternative to this embodiment, the rivet 1 with a horizontal cross-section of "V" can also be formed by connecting the ends of the two insert plates 103 at a 60-degree angle. This rivet 1 can also be adapted to the mesh holes of the three-dimensional geogrid 3. In addition, the connection angle between the ends of the two insert plates 103 in this embodiment is not limited to 60 degrees, but can also be 90 degrees. The forming angle can also be 30°, 45° or 120° to improve the adaptability of the rivet 1.

[0030] Example 3: like Figure 9 As shown in the figure, this embodiment illustrates another structure of the rivet 1. Specifically, the rivet 1 has a "V"-shaped structure and includes three insert plates 103, each with one side simultaneously connected to the axis. The sides of the three insert plates 103 form an equilateral triangle structure, that is, the included angle between the three insert plates 103 is 120°. At the same time, in this embodiment, the insertion end 101 is located at the axis of the rivet 1, so that the rivet structure can be vertically inserted into the soil along the axial direction.

[0031] In this embodiment, the tip of the insertion end 101 of the rivet rod 1 with the "human" shaped structure is located at the axis of the rivet rod 1, so that the rivet rod 1 can be inserted into the soil along the center of the rivet rod 1.

[0032] The insertion end 101 in this embodiment can be a tapered structure formed by circumferential cutting, or it can be a tapered structure insertion end 101 formed by individually cutting off the triangular sides of three insert plates 103.

[0033] Example 4: like Figure 10 As shown in the figure, this embodiment illustrates another structure of the rivet 1. Specifically, the rivet 1 has a cross-shaped structure and includes four insert plates 103 that are connected to the axis on one side at the same time.

[0034] In this embodiment, the rivet 1 adopts a cross-shaped structure to improve the strength of the rivet 1 in all directions, and its insertion end 101 is located at the axis so that the rivet 1 can be inserted into the soil along the center of the rivet 1.

[0035] The insertion end 101 in this embodiment can be a tapered structure formed by circumferential cutting, or it can be a tapered structure formed by cutting off the triangular sides of four insert plates 103 individually.

[0036] The rivet 1 in this embodiment can be applied to the mesh holes of the geogrid 3 with a rectangular structure.

[0037] Furthermore, in this embodiment, the rivet 1 can also be connected by six insert plates 103 to form a "rice" structure, thereby adapting to the grid holes of the hexagonal honeycomb geogrid 3. The included angle between the six insert plates 103 on the "rice" structure rivet 1 is 60°.

[0038] Further, the rivet rod 1 of this embodiment may also be connected by five insertion plates 103 to form a "da"-shaped structure, so as to adapt to the grid holes of the geogrid 3 with a pentagonal structure, and the included angle between every two of the five insertion plates 103 on the rivet rod 1 with the "da"-shaped structure is 72°.

[0039] Embodiment 5: As shown in Figure 11 this figure, this embodiment shows another structure of the rivet rod 1. Specifically, the horizontal cross-section of the rivet rod 1 is a circular structure, and the insertion end 101 is a conical structure. The rivet rod 1 of this embodiment may adopt a round rod structure with a diameter decreasing continuously from top to bottom, so that the rivet rod 1 can be quickly inserted into the soil, and the installation efficiency of the rivet rod 1 is effectively improved.

[0040] The rivet rod 1 of this embodiment may also adopt a straight rod structure, and the end thereof is subjected to annular cutting to form the insertion end 101 with a conical structure.

[0041] In this embodiment, the rivet rod 1 with a circular horizontal cross-section structure can improve the applicability of the rivet rod 1, making it suitable for fixing and installing grid holes of the geogrid 3 in different shapes, such as polygonal or circular grid holes.

[0042] Embodiment 6: As shown in Figures 12 to 14 this figure, this embodiment shows another structure of the rivet rod 1. Specifically, the rivet rod 1 includes a plurality of insertion plates 103, which are evenly spaced and arranged along the circumferential direction of the pressing end 102, so that the rivet rod 1 forms a hollow insertion groove 104 along the axial direction for inserting with the connection point 301 of the geogrid 3.

[0043] In this embodiment, there are 2 to 6 insertion plates 103, so that the plurality of insertion plates 103 can pass through a plurality of grid holes of the geogrid 3, and the hollow insertion groove 104 can be inserted on the connection point 301 at the center of the plurality of grid holes.

[0044] The structure of the rivet rod 1 in this embodiment can realize a wider range of ground fixation and laminated connection of the geogrid 3.

[0045] The structure of the rivet rod 1 in this embodiment is not limited by the grid hole structure of the geogrid 3, and can be used for fixing the multi-directional geogrid 3.

[0046] Referring to Figure 14 this figure, the rivet rod 1 with the hollow insertion groove 104 structure and the rivet rod 1 with the "T"-shaped structure can be installed on the geogrid 3 at the same time, wherein the rivet rod 1 with the hollow insertion groove 104 structure can be used for the laminated connection of multiple grid holes, and the rivet rod 1 with the "T"-shaped structure is used for the laminated connection of a single grid hole.

[0047] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
