Description

Technical Field

[0001] This invention belongs to the field of geocell technology, specifically relating to a geocell strip, locking component combination structure and its usage method. Background Technology

[0002] With the development of civil engineering construction, the requirements for foundation treatment, slope protection, road engineering, etc. are becoming increasingly stringent. The use of geocells is also increasing. The use of geocells faces the challenge of matching strips and locking devices. Existing locking devices are relatively complex to install and use, and their effect on stabilizing the installation of strips is poor, making the strips prone to slippage. Although some locking devices are relatively secure, their fixation relies on forceful compression, resulting in sharp points that cause stress concentration in the strips, making them prone to breakage and damage. Therefore, it is necessary to design a locking device with good fixing effect that does not cause stress concentration, as well as a strip that can be used in conjunction with it. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the inventors of this invention, through long-term exploration, experimentation, and continuous reform and innovation, have proposed a geocell strip, locking component combination structure and usage method. The strip is a single piece stretched and formed, woven into a mesh shape along the longitudinal or transverse direction. The strip is simple to process and easy to use, and the entire strip has better tensile strength. The locking component uses clamping ribs to compress the strip. The double-arc clamping structure has a continuous and natural arc connection and an S-shaped transition. While clamping, it does not have sharp surfaces, does not generate stress concentration, and the strip is not easily damaged or broken.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is to provide a geocell strip and locking component combination structure. It includes a locking component and a strip. The locking component consists of a first pressure block and a second pressure block. Both the first and second pressure blocks are staggered and continuously provided with S-shaped strip-shaped clamping ribs formed by a larger first arc-shaped depression and a smaller second arc-shaped protrusion, which are smoothly connected and tangentially transitioned. The depression of the first pressure block and the protrusion of the second pressure block match in shape to clamp the strip. The first and second pressure blocks are fastened together to form a channel on the inner side of the second arc. The reinforcing locking plate on the pressure block has a through hole connecting to this channel. An anchor is inserted into the through hole to fix the locking component to the ground.

[0005] A further preferred technical solution of the geocell strip and locking component combination structure according to the present invention is: the central angle β of the first arc is in the range of 120°≤β<180°, the central angle α of the second arc is in the range of 120°≤α<180°, and α=β.

[0006] A further preferred technical solution of the geocell strip and locking component combination structure according to the present invention is as follows: the strip is a strip integrally stretched and formed, and shearing openings or weak tear openings are longitudinally provided on the strip. The shearing openings or weak tear openings are arranged at unequal intervals and are regularly repeated or evenly spaced. The portion between adjacent shearing openings or weak tear openings is squeezed by compression ribs to form a locking piece.

[0007] A further preferred technical solution of the geocell strip and locking component combination structure according to the present invention is as follows: a reinforcing rib is provided on the strip along the longitudinal direction, the reinforcing rib is integrally formed with the strip, the reinforcing rib is parallel to the edge of the strip and is provided with the same length as the strip, the reinforcing rib protrudes from the surface of the strip on one or both sides and forms a groove fit relationship with the locking component, when one side protrudes, the other side is a plane or a corresponding recessed structure.

[0008] A further preferred technical solution of the geocell strip and locking component combination structure according to the present invention is: a reinforcing rib groove is provided on the surface of the clamping rib, the reinforcing rib groove is adapted to the reinforcing rib on the strip, and after the two clamping blocks are fastened, the reinforcing rib groove positions and clamps the reinforcing rib on the strip.

[0009] A further preferred technical solution of the geocell strip and locking component combination structure according to the present invention is: a locking piece is formed between any two adjacent punching and shearing openings or weak tear openings, each locking piece includes at least one reinforcing rib, and each clamping rib clamps one or more complete locking pieces.

[0010] A further preferred technical solution of the geocell strip and locking component combination structure according to the present invention is that: when in use, the strip is woven in an S-shape to connect all the fixed nodes, and the locking components are arranged in a zigzag shape between adjacent fixed nodes, so that each fixed node is double-layered.

[0011] A further preferred technical solution of the geocell strip and locking component combination structure according to the present invention is as follows: the mating gap formed by the first pressure block and the second pressure block is less than twice the thickness of the strip to compress and lock the strip. Alternating positioning locking keys and positioning locking holes are provided on the fastening surfaces on both sides of the first pressure block and the second pressure block. After fastening, the positioning locking keys penetrate or forcibly press the double-layer strip into the positioning locking holes, and at the same time position and lock the locking component and the strip, restricting the mutual displacement of the locking component and the strip.

[0012] A further preferred technical solution of the geocell strip and locking component assembly structure according to the present invention is as follows: a hollow locking pin is inserted into one side of the through hole of the reinforcing locking plate, and then a nail anchor is inserted into the hollow locking pin. The through hole is a cylindrical countersunk hole. The rear end of the hollow locking pin is provided with a protruding step that matches the recess of the cylindrical countersunk hole for installation and limiting. The nail anchor is U-shaped, and two nail feet are simultaneously inserted from the protruding step side of the two hollow locking pins and pass through the hollow locking pins to be nailed into the ground, thereby providing secondary reinforcement to the hollow locking pins and improving the strength of the locking component assembly.

[0013] A method for using a geocell strip and locking component combination structure, comprising: Node assembly: Lay the first strip layer in the first laying area, and wrap the entire first strip layer in an S-shape in the horizontal or vertical direction to form a diamond grid. Use locking devices to fix the strips at the intersection to form a geocell. Insert a U-shaped nail anchor into the through hole of a hollow locking pin with a protruding step in a locking device. Inter-group connection: In the second area adjacent to the first area, the second strip layer is laid in the same manner. At the locking member at the junction of the first and second areas, a U-shaped anchor is used to insert one nail into the positioning locking hole on one side of the locking member in the first area, and the other nail is inserted into the positioning locking hole on the same side of the adjacent locking member in the second area. The other nail is inserted in the same way into the corresponding positioning locking hole on the other side of the locking member in the first area and the locking member in the second area, thereby realizing the fixing of the strip across the area.

[0014] A further preferred technical solution of the method for using a geocell strip and locking component combination structure according to the present invention is as follows: when the locking component is installed on the strip, it ensures that the reinforcing rib is positioned in the reinforcing rib groove, and then the edge of the clamping rib tears the strip from the punching and shearing opening or the weak tear opening, and the compression deformation forms a locking piece; the locking deformation area of ​​the strip edge is squeezed by the positioning locking key of the locking component edge and the matching positioning locking hole, and the locking deformation area deforms into the positioning locking hole or is penetrated to further fix the strip.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages / benefits: 1. The strip is a single piece stretched and formed, woven into a mesh shape along the longitudinal or transverse direction. The strip is simple to process and easy to use, and the tensile strength of the whole strip is better. The locking part uses clamping ribs to clamp the strip. The clamping structure formed by the double arc has a continuous and natural arc connection and an S-shaped transition. While clamping, there are no sharp surfaces, so stress concentration does not occur and the strip is not easily damaged or broken.

[0016] 2. The strip and several reinforcing ribs are stretched and formed as a whole. The reinforcing ribs enhance the strength of the strip and improve its tensile strength. The locking part is provided with reinforcing rib grooves so that the reinforcing ribs fit into the reinforcing rib grooves. After the two pressure blocks are fastened, the reinforcing rib grooves position and press and lock the reinforcing ribs to give full play to the tensile strength of the reinforcing ribs.

[0017] 3. The shearing ends are provided with shearing arcs to avoid stress concentration in the strip at both ends of the shearing end, which would cause the strip to tear along the length of the strip at both ends of the shearing end (especially during the process of extruding the strip into a "figure 8" shape), thereby reducing the strength loss of the strip.

[0018] 4. Locking deformation zones are provided on both sides of the strip. The locking components are equipped with reinforcing ribs to enhance the compressive strength of the edge side of the locking components and improve the tensile and peel strength of the joint. Positioning locking keys and positioning locking holes are provided on the reinforcing ribs. After the two pressure blocks are engaged, the positioning locking keys press the double-layer strip into the positioning locking holes, positioning and locking both the locking components and the strip, restricting the mutual displacement of the locking components and the strip, and improving the tensile shear and peel strength of the joint.

[0019] 5. The back of the recess formed by the first arc is set as a V-shaped groove with an arc bottom. The V-shaped groove with an arc bottom naturally transitions and connects with the surface of the locking part, ensuring that the locking part does not generate stress concentration during the production process and that the locking part is subjected to more uniform force. The V-shaped groove with an arc bottom is an open structure, which can be quickly demolded without demolding during production and without damaging the locking part.

[0020] 6. After the first and second pressure blocks are engaged, the fitting gap formed between the indentation of the first arc and the second arc is less than twice the thickness of the strip. Within the pressing range of the locking element, the two layers of strip are compressed and deformed together (fully utilizing the compression stiffness of the strip) to ensure that the locking element has a higher locking pressure on the strip and improve the anti-slip force of the strip after it is locked.

[0021] 7. The spacing between adjacent clamping ribs is greater than or equal to zero and equal to the width of the strip's punching and shearing notch. This ensures that the locking element does not cause concentrated stress on the hollow locking pin under the action of external force on the strip after locking, so as to make full use of the shear and tensile strength of the hollow locking pin and improve the joint strength.

[0022] 8. The hollow lock stop pin is located in the channel formed by the engagement of the first and second pressure blocks on the inner side of the second arc, realizing the self-locking between the hollow lock stop pin and the locking component. This ensures that the hollow lock stop pin will not fall off during production, transportation, and construction, guarantees the strength of the joint, strengthens the fit between the cylindrical countersunk hole of the locking plate and the protruding step set at the rear end of the hollow lock stop pin, and ensures that the hollow lock stop pin will not come out of the locking component when the anchor is inserted into the hollow lock stop pin from the protruding step, thus guaranteeing the locking effect of the locking component.

[0023] 9. The U-shaped nail anchor is inserted into the anchor hole from the side of the locking boss, which can realize the anchoring after appropriate geotechnical tension or the rapid connection between groups during construction. It changes the traditional anchoring method and inter-group connection. Without damaging the cell strip and nodes, it can realize rapid construction and provide secondary reinforcement to the hollow locking pin, further improving the locking strength of the nodes.

[0024] 10. The rounded bottom V-shaped groove on the back of the locking part makes it easy to demold during the manufacturing of the briquette. After the backfill is completed, the rounded bottom V-shaped groove on the back of the locking part can effectively engage with the backfill, enhance the engagement between each node and the backfill, and improve the reinforcement effect of the cell on the soil.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. Therefore, the detailed description of the embodiments of this invention provided below is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0040] Example 1: like Figures 1-11As shown, a geocell strip and locking component combination structure is presented. It includes a locking element 200 and a strip. The locking element 200 is composed of a first pressure block 210 and a second pressure block 220. The first pressure block 210 and the second pressure block 220 are both staggered and continuously provided with S-shaped strip-shaped pressing ribs 201 formed by the tangential transition of the recess formed by the larger first arc 2011 and the protrusion formed by the smaller second arc 2012. The recess of the first pressure block 210 and the protrusion of the second pressure block 220 are matched to press the strip. The fitting gap formed by the first pressure block 210 and the second pressure block 220 is less than twice the thickness of the strip to compress and lock the strip. A channel is formed on the inner side of the second arc 2012 (this channel is the locking pin channel, used to accommodate the pin body of the hollow locking pin). The reinforcing locking plate 250 on the pressure block has a through hole (cylindrical countersunk hole 251) connecting the channel. The nail anchor 240 is inserted into the through hole to fix the locking element 200 to the ground. The anchor 240 passes through the through hole and embeds itself into the ground, ensuring the locking member 200 and the strip are stably fixed together. In this embodiment, the hollow locking pin 230 and the cylindrical countersunk hole 251 are a mating structure. The cylindrical countersunk hole 251 is only needed when there is a hollow locking pin with a protruding step. When the locking member is directly fixed using the anchor, the hollow locking pin 230 and the cylindrical countersunk hole 251 are not required. When the first pressure block 210 and the second pressure block 220 are engaged, the reinforcing locking plates on the two pressure blocks are located on both sides to form a symmetrical structure.

[0041] The locking piece 120 is embedded in the locking element 200, and the reinforcing rib 130 cooperates with the reinforcing rib groove 2013 on the reinforcing rib 204 to achieve multiple reinforcements. The positioning locking key 202 cooperates with the positioning locking hole 203 to further prevent loosening. The hollow locking pin 230 is limited by the protruding step 231 to enhance the tensile strength of the structure. This combined structure is easy to install and is suitable for the rapid locking and long-term stability of geotextiles under complex terrain conditions.

[0042] The central angle β of the first arc 2011 is in the range of 120°≤β<180°, and the central angle α of the second arc 2012 is in the range of 120°≤α<180°, and α=β, so that they can be stably overlapped and the mating clearance is guaranteed. This ensures that the locking pressure of the locking component on the strip is uniform and stable without damaging the strip. Of course, the angle can be selected within a certain range, as long as there is no sharp contact surface and it is easy to manufacture. The concave part of the first arc 2011 and the convex part of the second arc 2012 are tangentially and smoothly connected, which effectively disperses stress concentration and enhances the durability of the structure.

[0043] The strip is integrally stretched into a strip shape, with longitudinally arranged punched shear slits 110 (or weak tear slits, hereinafter referred to as punched shear slits). The area between adjacent punched shear slits 110 or weak tear slits is compressed by clamping ribs 201 to form locking pieces 120. Alternatively, it can be without reinforcing ribs 130, which represents the most basic structure of the strip. After the strip 100 is compressed and deformed, it forms... Figure 5 The planar shape becomes Figure 6 The three-dimensional shape of the strip is such that the area between the two shearing notches 110 deforms to form a locking piece 120. The locking piece 120 can be bent upwards or downwards to form an installation structure that cooperates with the locking member 200, achieving a stable installation. The shearing notches or weak tear notches are set at unequal intervals and are regularly repeated or evenly spaced. That is, the shearing notches only need to correspond to the position of the clamping ribs, and do not necessarily need to be evenly spaced. The shearing arcs 111 at both ends of the shearing notches or weak tear notches are used to prevent stress concentration from tearing the strip.

[0044] A reinforcing rib 130 of equal length to the strip 100 is provided longitudinally along the strip. The reinforcing rib 130 is integrally formed with the strip 100 and is arranged parallel to the edge of the strip 100. The reinforcing rib 130 protrudes from the surface of the strip on one or both sides and forms a groove with the locking member 200. When one side protrudes, the other side is a plane or a corresponding recessed structure. The reinforcing rib 130 is integrally formed with the strip 100 and extends along the length of the strip 100, and is evenly distributed on both sides of the strip 100 to improve the overall tensile strength and structural stability of the strip 100. The reinforcing rib 130 protrudes from the surface of the strip 100 on one or both sides and forms a groove with the locking member 200. When one side protrudes, the other side is a plane or a corresponding recessed structure. The reinforcing ribs 130 on the strip 100 can be raised on one or both sides, or raised on one side and recessed on the other. The locking member 200 can be fitted with corresponding protrusions or recesses for installation. The reinforcing ribs 130 can be evenly distributed on the strip 100, or unevenly distributed, depending on actual needs. In this embodiment, the strip's length direction is longitudinal, and its width direction is transverse.

[0045] The reinforcing rib 130 is parallel to the edge of the strip 100 and is of the same length as the strip 100. In this embodiment, the edge of the strip 100 refers to the long side of the elongated strip 100, that is, the width is defined by the short sides at both ends of the strip 100, and the length is defined by the long side (i.e., the edge of the strip 100). Of course, setting the length of the reinforcing rib 130 to be equal to the length of the strip 100 is only a more reasonable solution. In fact, the length of the reinforcing rib 130 only needs to have a reinforcing effect, and its two ends can be relatively close to the edge of the strip 100. The setting of the reinforcing rib 130 can effectively improve the overall tensile strength and deformation resistance of the strip 100, especially maintaining structural stability under complex stress environments.

[0046] The reinforcing rib 130 can be any of the following shapes: semi-circular, arc-shaped, or rounded trapezoidal. Generally, the reinforcing rib 130 can be in a form without obvious sharp edges, so that it can be easily installed and positioned with the locking part 200. Of course, the reinforcing rib 130 can also be other reasonable shapes.

[0047] The second arc 2012 protrusions of the clamping ribs 201 of the first clamping block 210 are continuously staggered left and right. A reinforcing locking plate 250 is provided on the end face. The second arc 2012 protrusions of the clamping ribs 201 of the second clamping block 220 are also continuously staggered left and right and their shapes are complementary to those of the clamping ribs 201 of the first clamping block 210 when they are fastened. The first clamping block 210 and the second clamping block 220 fasten to form a locking member 200, which clamps the strip and forms a channel inside the second arc 2012. The reinforcing locking plate 250 has a through hole connecting the channel. A hollow locking pin 230 is inserted into one side of the reinforcing locking plate 250. The hollow locking pin 230 is located in the through hole, and a nail anchor 240 is inserted into the hollow locking pin 230. The nail anchor 240 passes through the hollow locking pin 230 and is anchored into the ground, realizing the fixed connection between the locking member 200 and the foundation.

[0048] A reinforcing rib groove 2013 is provided on the surface of the clamping rib 201. The reinforcing rib groove 2013 is adapted to the reinforcing rib 130 on the strip. After the two clamping blocks are engaged, the reinforcing rib groove 2013 positions and clamps the reinforcing rib 130 on the strip. This effectively prevents the strip from shifting laterally or twisting under stress. Its cross-sectional shape corresponds to the shape of the reinforcing rib 130 on the strip, and its position also corresponds.

[0049] A locking tab 120 is formed between any two adjacent shearing cuts 110 or weak tear openings. Each locking tab 120 includes at least one reinforcing rib 130. Each clamping rib 201 clamps one or more complete locking tabs 120. The spacing between adjacent clamping ribs 201 is greater than or equal to zero and is an integer multiple of the width of the shearing cut 110 or weak tear opening of the strip. It is sufficient to ensure that both sides of a single clamping rib 201 are corresponding shearing cuts 110. Of course, the locking tab 120 can be a single locking tab 120 between adjacent shearing cuts 110, or it can be a large area locking tab 120 formed by the area between multiple shearing cuts 110.

[0050] The entire strip is woven in an S-shape to connect all fixed nodes during use. Between adjacent fixed nodes formed by the locking elements 200, a zigzag arrangement is created, forming a square or diamond-shaped grid. This facilitates the restriction of filler flow, enhances the uniformity and strength of the pouring, and reduces pouring difficulty. Furthermore, at each diamond-shaped fixed node, there is a double-layer overlap (the outermost edge may be a single layer, requiring only single-layer fixing; if necessary, a dedicated single-layer locking element 200 can be used). The double-layered strip is compressed and deformed by the locking elements 200, forming a good fixation. And, as... Figure 3 and Figures 5-7 As shown, the punched and sheared notches 110 (or weak parts, which can also be understood as pre-set grooves that are easily torn or broken, etc.) of the first strip layer 101 and the second strip layer 102 are completely overlapped to ensure that the locking piece 120 is formed synchronously when the locking member 200 is pressed, thereby achieving simultaneous fixation of the double-layer structure and avoiding local failure caused by uneven stress. This overlap design makes the two strip layers coordinate and consistent during deformation, enhancing the reliability of the connection. The first strip layer 101 and the second strip layer 102 mentioned in this invention actually refer to the upper and lower layers formed at the node of a whole strip, not two strips, but to the two-layer structure formed by the strip itself through folding during laying. In the second laying area, the same whole strip continues to be extended and folded along an S-shaped path. Of course, the description of the area is a spatial concept used to distinguish the laying sections of the strip at different locations. It does not have a strict range limitation; it can be an area after the use of a strip is completed, or it can be different sections in the continuous laying process. By continuously extending and laying several strips between adjacent areas, a seamless connection of the overall structure is achieved, and the upper and lower layers are maintained at the nodes.

[0051] Alternating positioning locking keys 202 and positioning locking holes 203 are provided on the mating surfaces of both sides of the first pressure block 210 and the second pressure block 220. After mating, the positioning locking keys 202 penetrate or forcefully press the double-layer strip into the positioning locking holes 203, simultaneously positioning and locking the locking member 200 and the strip, restricting mutual misalignment between the locking member 200 and the strip. This improves the tensile shear and peel strength of the joint, effectively enhancing the overall stability and load-bearing capacity of the connection joint. The positioning locking keys 202 and positioning locking holes 203 can be arranged in alternating groups of several.

[0052] After inserting a hollow lock pin 230 into one side of the countersunk hole 251 of the reinforcing locking plate 250, a nail anchor 240 is then inserted into the hollow lock pin 230. The rear end of the hollow lock pin 230 has a protruding step 231 that matches the recess of the countersunk hole 251 for installation and limiting. This ensures the hollow lock pin 230 is firmly positioned, preventing axial movement. The protruding step 231 fits snugly against the recessed surface of the countersunk hole, forming a reliable axial constraint and improving the overall connection stability. The nail anchor 240 is U-shaped, with two nail feet simultaneously inserted from the protruding steps 231 of the two hollow lock pins 230 and passing through the hollow lock pins 230 into the ground, providing secondary reinforcement to the hollow lock pins 230 and improving the strength of the locking components 200 after assembly. The U-shaped nail anchor 240 allows for simultaneous insertion into two holes for fixation, facilitating operation. It should be noted that in this embodiment, the locking pin is an optional accessory. The first and second pressure blocks can be directly fixed using nail anchors, but using the locking pin is more stable and less likely to squeeze the nail anchors.

[0053] The recessed back side formed by the first arc 2011 is configured as a rounded-bottom V-shaped groove 2014 to facilitate demolding and avoid stress concentration in the locking part 200 during production. This also prevents the locking part 200 from becoming difficult to demold due to adhesion after molding. The included angle of the rounded-bottom V-shaped groove 2014 only needs to facilitate mold demolding without affecting structural strength; specific requirements are not specified.

[0054] Example 2: Based on Example 1, a method for using a geocell strip and locking component combination structure is provided, which is implemented using the aforementioned geocell strip and locking component combination structure, and includes: Node assembly: Lay the first strip in the first laying area, and wind the entire first strip in an S-shape in the horizontal or vertical direction to form a diamond grid. At the intersection of the strips, use locking member 200 to fix it to form a geocell. Insert a U-shaped nail anchor 240 into the through hole of a hollow locking pin 230 with a protruding step 231 in a locking member 200. Inter-group connection: The second strip is laid in the same manner in the second area adjacent to the first area. At the locking member 200 at the junction of the first and second areas, one nail of the first U-shaped anchor 240 is inserted into the positioning locking hole 203 on one side of the locking member 200 in the first area, and the other nail is inserted into the positioning locking hole 203 on the same side of the adjacent locking member 200 in the second area. The second U-shaped anchor 240 is inserted into the corresponding positioning locking hole 203 on the other side of the locking member 200 in the first area and the locking member 200 in the second area in the same manner, so as to realize the fixing or node connection of the strip across the area.

[0055] When the locking member 200 is installed on the strip, it ensures that the reinforcing rib 130 is positioned in the reinforcing rib groove 2013. Then, the edge of the clamping rib 201 tears the strip from the punching and shearing opening 110 or the weak tear opening, compressing and deforming it to form the locking piece 120. The locking deformation area 140 on the edge of the strip is compressed by the positioning locking key 202 on the edge of the locking member 200 and the matching positioning locking hole 203. The locking deformation area 140 deforms into the positioning locking hole 203 or is penetrated to further fix the strip. When the locking member 200 and the strip are subjected to external tensile force, the multi-point engagement of the positioning locking key 202 and the positioning locking hole 203 achieves stress dispersion, effectively preventing local tearing propagation. At the same time, the stepped design of the hollow locking pin 230 can limit the axial displacement of the U-shaped nail anchor 240 and improve the shear resistance of the connection node. Under complex terrain conditions, the diamond grid structure can adapt to the surface undulation by adjusting the S-shaped winding spacing to maintain uniform overall stress. At this point, the strip can be made of plastic material that is not easily squeezed or torn, or other materials that meet the requirements.
