Description

Technical Field

[0001] This utility model relates to the field of geocell technology, specifically to a fused fastener node type geocell. Background Technology

[0002] Geocells are currently widely used in shallow foundation treatment, slope erosion control, and urban large pipeline support projects, and are a promising foundation engineering construction material.

[0003] In existing technologies, geocell nodes are typically connected using methods such as welding, riveting, or injection molding to form connection nodes. However, geocell nodes formed by these conventional methods have poor mechanical properties. When the geocell is subjected to large lateral tensile forces, the nodes are prone to failure, causing the two bands at the node location to separate. This leads to the destruction of the integrity of the geocell mesh structure and the inability to effectively restrain the filling material within the cell.

[0004] To this end, our company has developed a series of geocells that are connected at the nodes by fasteners, such as the geocell with a fastener node disclosed in Chinese patent document CN202520459884.0. It is formed by setting two fasteners that fasten in opposite directions at the node position, clamping the belt at the node between the two fasteners, and locking the two fasteners by the insertion rod part, thereby forming a reliable geocell node.

[0005] However, during the production and manufacturing process of this geocell product, our company found that there are some difficulties in inserting the insertion rod of the geocell into the fasteners that are fastened to the opposite side: if the insertion rod is made slightly thinner, it is easy to loosen and slip out after insertion, and a locking device is required accordingly. If the insertion rod is exactly matched with the corresponding through hole, the slight assembly error when the fastener is fastened will make it difficult to insert the insertion rod. Utility Model Content

[0006] The purpose of this utility model is to provide a fusion-welded fastener node type geocell, which can at least partially overcome the above-mentioned technical problems. It can form a reliable fastener connection node at the node of the geocell, and the allowable assembly error when two fasteners are fastened in opposite directions is more relaxed. It also eliminates the plug part, making the production process simpler and faster.

[0007] This utility model provides a welded fastener-type geocell, including a belt and fasteners. Each fastener includes a base, multiple bosses, and multiple first grooves. The bosses are arranged in an array above the base along its length and are fixedly connected to the base. One end face of one boss coincides with the first end face of the base. A first groove is formed on the side of the base away from the first end face of each boss, and for any given first groove, it is adjacent to the adjacent boss. At the node, the belt has multiple strip-shaped through holes arranged in an array along its width. The length direction of the strip-shaped through hole is parallel to the length direction of the belt body, and the strip-shaped through hole penetrates the belt body along the thickness direction of the belt body; each of the strip-shaped through holes divides the belt body at the node into multiple strips of equal width; the dimension of the boss along the length direction of the base body is defined as the thickness of the boss, and the dimension of the first groove along the length direction of the base body is defined as the thickness of the first groove; the thickness of the boss is greater than the thickness of the first groove, and the width of the strip is less than the thickness of the first groove; when the two fasteners are fastened to each other, the boss of one fastener corresponds to the first groove of the other fastener.

[0008] Furthermore, an embedded rod is embedded in the base below any boss and / or any boss, the embedded rod being arranged along the length direction of the base, and the length of the embedded rod being equal to the thickness of the boss.

[0009] Furthermore, the cross-sectional shape of the boss is arc-shaped, and the chord of the arc coincides with the upper surface of the base; the cross-sectional shape of the first groove is arc-shaped, and the chord of the arc coincides with the upper surface of the base.

[0010] Furthermore, the axes of the boss and the first groove coincide, and the radius of the first groove is greater than the radius of the boss.

[0011] Furthermore, an end plate is provided adjacent to the second end face of the base away from the boss. When the two fasteners are fastened to each other, the bosses of the two fasteners, the first groove and the projection of the base along the length of the base are all located within the projection of the end plate along the length of the base.

[0012] Furthermore, for any boss, multiple second grooves are formed vertically on both end faces of the boss; for any first groove, multiple second grooves are formed vertically on both end faces of the first groove; multiple second grooves are formed vertically on the end face of the end plate facing the boss and on the first end face.

[0013] Furthermore, a plurality of protruding ridges are provided on the strip, the length direction of the protruding ridges being perpendicular to the length direction of the strip, and the protruding ridges are arranged in an array along the length direction of the strip.

[0014] Furthermore, a plurality of reinforcing wires are sandwiched inside the belt body, and the length direction of the reinforcing wires is parallel to the length direction of the belt body.

[0015] Furthermore, the reinforcing wire is selected from one or more of steel strand, steel wire with a threaded steel structure, and braided cotton thread.

[0016] Furthermore, several water-permeable holes are provided on the belt section between any two adjacent nodes, and the water-permeable holes penetrate the belt along the thickness direction of the belt.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. The fusion-welded fastener node type geocell provided in this embodiment melts the preset surfaces of two fasteners and then fastens them together, forming a tightly connected geocell node based on the principle of plastic welding. Since the width of the boss is greater than the width of the first groove, the two surfaces fit together more tightly after heating, effectively preventing problems such as loose structure or shrinkage cavities at the connection point after the molten plastic solidifies. This also makes the connection at the fusion point tighter. Furthermore, excess molten plastic is squeezed and flows during the fastening process, filling the area around the strip and further strengthening the connection between the fastener and the strip. It is worth noting that in this geocell, the connection of the fasteners at the node no longer depends on the insertion rod, which can significantly save assembly time during node connection and promote efficient geocell production.

[0019] 2. The fusion-bonded fastener node type geocell provided in this embodiment of the invention has an embedded rod. When the preset surface on the fastener melts, the plastic at both ends of the embedded rod is melted. After the two fasteners are fastened together, the two ends of the embedded rod are wrapped by the plastic that has been re-solidified in the fusion area. The re-solidified plastic body achieves a reinforced connection with the bosses on both sides through the embedded rod, making the node more resistant to external forces in the opposite direction to the fastening direction.

[0020] 3. The fusion-welded fastener node type geocell provided in this embodiment, by setting a second groove, divides the surface to be melted into multiple small areas instead of the entire surface. This allows energy to rapidly accumulate in the relatively protruding parts when these surfaces are melted, resulting in rapid and smooth melting. Especially when using ultrasonic welding, such a second groove on the surface to be melted effectively guides the fusion, allowing the melting of the surface to proceed from point lines to a surface, which is beneficial for rapid and uniform melting. Furthermore, when two fasteners are fastened together, this second groove facilitates gas discharge, preventing gas from being trapped in the first groove by the molten plastic, thus ensuring the quality of the fastener fusion. In addition, when two fasteners are fastened together, the molten plastic of one fastener can flow into the second groove of the other fastener under pressure, increasing the fusion contact area and enhancing the mechanical properties of the fusion node.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explaining the utility model only and are not intended to limit the utility model. It should be noted that this utility model is already in the actual research and development stage.

[0033] Geocells are currently widely used in shallow foundation treatment, slope erosion control, and urban large pipeline support projects, and are a promising foundation engineering construction material.

[0034] In existing technologies, geocell nodes are typically connected using methods such as welding, riveting, or injection molding to form connection nodes. However, geocell nodes formed by these conventional methods have poor mechanical properties. When the geocell is subjected to large lateral tensile forces, the nodes are prone to failure, causing the two bands at the node location to separate. This leads to the destruction of the integrity of the geocell mesh structure and the inability to effectively restrain the filling material within the cell.

[0035] To this end, our company has developed a series of geocells that are connected at the nodes by fasteners, such as the geocell with a fastener node disclosed in Chinese patent document CN202520459884.0. It is formed by setting two fasteners that fasten in opposite directions at the node position, clamping the belt at the node between the two fasteners, and locking the two fasteners by the insertion rod part, thereby forming a reliable geocell node.

[0036] However, during the production and manufacturing process of this geocell product, our company found that there are some difficulties in inserting the insertion rod of the geocell into the fasteners that are fastened to the opposite side: if the insertion rod is made slightly thinner, it is easy to loosen and slip out after insertion, and a locking device is required accordingly; if the insertion rod is exactly matched with the corresponding through hole, the slight assembly error when the fastener is fastened will make it difficult to insert the insertion rod.

[0037] To address this, this utility model proposes a fusion-bonded fastener node type geocell, which can form a reliable fastener connection node at the node of the geocell, and has a more lenient allowance for assembly error when two fasteners are fastened together. It also eliminates the plug part, making the node structure simpler and the production process simpler and faster.

[0038] Example 1:

[0039] like Figures 1 to 5 As shown, this embodiment provides a welded fastener node type geocell, including a belt body 1 and fasteners 2;

[0040] The fastener 2 includes a base 21, a plurality of bosses 22 and a plurality of first grooves 23. Each of the bosses 22 is arranged in an array above the base 21 along the length direction of the base 21 and is fixedly connected to the base 21. The end face of one boss 22 coincides with the first end face 24 of the base 21. A first groove 23 is formed on the side of the base 21 away from the first end face 24 of each boss 22. For any first groove 23, the first groove 23 is adjacent to the adjacent boss 22.

[0041] At the node, the strip body 1 is provided with a plurality of strip-shaped through holes 11 arranged in an array along the width direction. The length direction of the strip-shaped through holes 11 is parallel to the length direction of the strip body 1, and the strip-shaped through holes 11 penetrate the strip body 1 along the thickness direction. Each strip-shaped through hole 11 divides the strip body 1 at the node into a plurality of strips 12 of equal width.

[0042] The thickness of the boss 22 is defined as the dimension of the boss 22 along the length of the base 21, and the thickness of the first groove 23 is defined as the dimension of the first groove 23 along the length of the base 21; the thickness of the boss 22 is greater than the thickness of the first groove 23, and the width of the strip 12 is less than the thickness of the first groove 23.

[0043] When the two fasteners 2 are fastened to each other, the protrusion 22 of one fastener 2 corresponds to the first groove 23 of the other fastener 2.

[0044] In the welded fastener node type geocell provided in this embodiment, fastener 2 is a plastic part with weldable properties, and its node is connected through the following steps:

[0045] First, align the two strips 1 to be connected at the node, so that the strip-shaped through holes 11 on the two strips 1 coincide one by one; then, place the two fasteners 2 facing each other, and heat and melt the two end faces and the upper convex arc surface of each boss 22, as well as the two end faces and the lower concave arc surface of each first groove 23; next, place the prepared strip 1 between the two facing fasteners 2, so that each strip 12 corresponds one by one with each first groove 23; finally, fasten the two fasteners 2 facing each other, so that the boss 22 is inserted into the corresponding first groove 23, and the melted part cools and solidifies, completing the connection of the node.

[0046] It should be understood that heating the fastener 2 to melt its preset surface can be based on electric heating plate heating, vibration friction heating, and ultrasonic heating. When ultrasonic welding technology is used, the width of the strip-shaped through hole 11 can be smaller, or even replaced by a slit of equal length. Preferably, the strip 1 at the node position can also be pre-pressed (the cavity of which is set according to the shape of the fastener 2, fitting the cavity after the two fasteners 2 are fastened together) using a corresponding mold (the cavity of which is set according to the shape of the fastener 2, fitting the cavity after the two fasteners 2 are fastened together) to press the strip 1 at the node into the shape shown. Figure 2 (as shown in the shape), which makes it easier to directly embed one of the fasteners 2 after the preset surfaces of the two fasteners 2 have melted and before they are fastened.

[0047] Accordingly, the fusion-welded fastener node type geocell provided in this embodiment, by melting the preset surfaces of two fasteners 2 and fastening them towards each other, can form a tightly connected geocell node based on the principle of plastic welding. Since the width of the boss 22 is greater than the width of the first groove 23, when the corresponding surfaces are heated and fastened towards each other, they can fit more tightly, effectively preventing problems such as loose structure or shrinkage cavities at the connection point after the molten plastic solidifies. This also makes the connection at the fusion point tighter. Furthermore, excess molten plastic is squeezed and flows during the fastening process, filling the area around the strip 12 and further strengthening the connection between the fastener 2 and the strip 12. It is worth noting that in this geocell, the connection of the fasteners 2 at the node no longer depends on the insert rod, which can significantly save assembly time during node connection and promote efficient geocell production.

[0048] Preferably, refer to Figures 3 to 5 The cross-sectional shape of the boss 22 is arc-shaped, and the chord of the arc coincides with the upper surface of the base 21.

[0049] The first groove 23 has an arc-shaped cross-section, and the chord of the arc coincides with the upper surface of the base 21.

[0050] The axes of the boss 22 and the first groove 23 coincide, and the radius of the first groove 23 is greater than the radius of the boss 22.

[0051] Accordingly, in this embodiment, the upper convex arc surface of the boss 22 and the lower concave arc surface of the first groove 23 are both cylindrical surfaces. After the two fasteners 2 are fastened together, the strip 12 sandwiched between the two fasteners 2 can be in an arc shape, thereby reducing damage to the strip 12, which is beneficial to maintaining the tensile strength of the strip body 1 and preventing the node from becoming a weak point in tensile strength due to damage to the strip 12 of the strip body 1 caused by welding the two fasteners 2.

[0052] Example 2:

[0053] like Figure 3 , Figure 4 , Figure 6 As shown, this embodiment is based on embodiment 1, the difference being that in this embodiment:

[0054] An embedded rod 25 is embedded in the base 21 below any boss 22 and / or any boss 22. The embedded rod 25 is arranged along the length direction of the base 21, and the length of the embedded rod 25 is equal to the thickness of the boss 22.

[0055] Accordingly, the fused fastener node type geocell provided in this embodiment, by setting the embedded rod 25, when the preset surface on the fastener 2 melts, the plastic at both ends of the embedded rod 25 is melted, and after the two fasteners 2 are fastened together, the fused area at both ends of the embedded rod 25 (please refer to) Figure 6 , Figure 6 The gray area schematically shows the fusion area where the molten plastic from the two fasteners merges and solidifies. The re-solidified plastic body then achieves a reinforced connection with the two side bosses 22 through the insert rod 25, making the node more resistant to external forces in the opposite direction to the fastening direction.

[0056] It should be understood that the height of the embedded rod 25 should be set reasonably to ensure that it can contact the other fastener 2 when the two fasteners 2 are fastened, while avoiding interference with the embedded rod 25 in the other fastener 2.

[0057] Example 3:

[0058] This embodiment is based on Embodiment 1, with the difference being that in this embodiment:

[0059] An end plate 26 is provided adjacent to the second end face of the base 21 on the side away from the boss 22. When the two fasteners 2 are fastened to each other, the boss 22, the first groove 23 and the projection of the base 21 along the length of the base 21 of the two fasteners 2 are all located within the projection of the end plate 26 along the length of the base 21.

[0060] By setting the end plate 26, when the two fasteners 2 are fastened to each other, one fastener 2 can be pressed towards the end plate 26 of the other fastener 2, which makes it easier to clamp and fix the two fasteners 2 that are fastened to each other, so that they can maintain a stable fastening state until the molten plastic cools and solidifies; in addition, the end plate 26 also helps to protect the edge of the belt body 1 in the width direction at the node.

[0061] More preferably, on any boss 22, multiple second grooves 221 are formed in the vertical direction on both end faces of the boss 22.

[0062] For any first groove 23, multiple second grooves 221 are formed in the vertical direction on both end faces of the first groove 23;

[0063] Multiple second grooves 221 are formed vertically on the end face of the end plate 26 facing the boss 22 and on the first end face 24.

[0064] Accordingly, the fusion-bonded fastener node type geocell provided in this embodiment, by setting these second grooves 221, makes the surface to be melted no longer the entire surface, but divided into multiple small areas. Thus, when these surfaces to be melted are melted, energy can be rapidly concentrated in the relatively protruding parts, thereby making the melting process rapid and smooth. Especially when using ultrasonic welding, opening such second grooves 221 on the surface to be melted can effectively guide the fusion, so that the melting of the surface to be melted is from point and line to surface, which is conducive to the rapid and uniform melting of the surface to be melted. Furthermore, when the two fasteners 2 are fastened towards each other, such second grooves 221 can facilitate the exhaust of gas, preventing gas from being blocked by the molten plastic in the first groove 23, thereby helping to ensure the welding quality of the fasteners 2. In addition, when the two fasteners 2 are fastened towards each other, the molten plastic of one fastener 2 can flow into the second groove 221 of the other fastener 2 under pressure, thereby increasing the welding contact area of ​​the welding part and helping to strengthen the mechanical properties of the welding node.

[0065] Example 4:

[0066] like Figure 7 As shown, this embodiment is based on embodiment 1, the difference being that in this embodiment:

[0067] A plurality of protruding ridges 121 are provided on the strip 12, the length direction of the protruding ridges 121 is perpendicular to the length direction of the strip 12, and the protruding ridges 121 are arranged in an array along the length direction of the strip 12.

[0068] Accordingly, after the two fasteners 2 are fastened together, the protruding rib 121 can be embedded into the molten plastic, thereby effectively strengthening the connection between the strip 12 and the fastener 2, and effectively limiting the relative sliding of the strip 1 and the fastener 2 along the length of the strip 1.

[0069] Example 5:

[0070] like Figure 8 As shown, this embodiment is based on embodiment 1, the difference being that in this embodiment:

[0071] A plurality of reinforcing wires 122 are sandwiched inside the belt body 1, and the length direction of the reinforcing wires 122 is parallel to the length direction of the belt body 1.

[0072] The reinforcing wire 122 is selected from one or more of steel strand, steel wire with a threaded steel structure, and braided cotton thread.

[0073] For any strip 12, the strip 12 shall include at least one reinforcing wire 122.

[0074] Accordingly, the fusion-welded fastener node type geocell provided in this embodiment can effectively improve the tensile strength of the geocell by setting reinforcing wire 122. The reinforcing wire 122 is selected from steel strand, steel wire with threaded steel structure, and braided cotton thread, so that the reinforcing wire 122 and the main body of the belt 1 are more tightly bonded, which helps to prevent the reinforcing wire 122 and the main body of the belt 1 from separating when the belt 1 is under tension.

[0075] More preferably, a plurality of water-permeable holes 13 are provided on the section of the belt body 1 between any two adjacent nodes, and the water-permeable holes 13 penetrate the belt body 1 along the thickness direction of the belt body 1.

[0076] The water-permeable hole 13 is opened between two adjacent reinforcing wires 122.

[0077] Preferably, the water-permeable hole 13 is a strip-shaped hole, and the length direction of the strip-shaped hole is parallel to the length direction of the belt body 1.

[0078] Accordingly, the fused fastener node type geocell provided in this embodiment can drain water through the permeable holes 13 during use, avoiding the accumulation of a large amount of rainwater in the geocell, effectively reducing the tensile force on the geocell, and preventing the overall landslide of the geocell laying layer induced by water accumulation in the geocell; and the permeable holes 13 are opened to avoid the reinforcing wires 122 and are designed as strip holes, which can minimize the impact of opening the permeable holes 13 on the tensile strength of the belt 1, so that the belt 1 still has a high tensile strength.

[0079] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
