[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] As attached Figure 1 , 2 , 3 and attached Figure 4 As shown:

[0037] Embodiment 1: This embodiment provides a geocell, comprising at least two sheets 1 and connection nodes 2; the sheet 1 is divided into a plurality of active layers 102 by a dividing seam 101; the connection node 2 comprises two mutually engaged node connection fasteners 201, a plurality of pressing blocks 2012 are arranged on the node connection fastener 201, a pressing groove 2014 is arranged between adjacent pressing blocks 2012, the pressing blocks 2012 are adapted to the pressing groove 2014, and the two node connection fasteners 201 are connected by a hinge shaft 202; the plurality of active layers 102 are staggered into two groups, and the two groups of active layers 102 are respectively located in the pressing grooves 2014 of the two node connection fasteners 201.

[0038] The sheet 1 is divided into a plurality of movable layers 102 by a dividing seam 101, and the movable layers 102 are staggered up and down to be divided into two groups, that is, from top to bottom, the first layer is the first group, the second layer is the second group, the third layer is the first group, and the fourth layer is the second group, and so on and so forth. Then, the two groups of movable layers 102 are respectively pushed into the pressing grooves 2014 of the two node connecting fasteners 201, and then the two node connecting fasteners 201 are engaged with each other, and the movable layers 102 can be pressed and fixed in the pressing grooves 2014 by the pressing blocks 2012 to ensure the stability of the connecting nodes 2. By staggering the two groups of movable layers 102 up and down, it is possible to prevent the connecting nodes 2 from being separated from the sheet 1 from the top or bottom, and at the same time prevent the connecting nodes 2 from being separated from the dividing seam 101 area, thereby ensuring the relative position stability of the connecting nodes 2 and the sheet 1, and firmly hinge the adjacent sheets 1 together to improve the overall stability of the geocell.

[0039] A hollow area is formed between the movable layers 102 on both sides in the pressing grooves 2014 of the two node connection fasteners 201 for filling the pressing blocks 2012 for pressing and fixing. The hollow area includes but is not limited to arc or diamond shapes.

[0040] Specifically, a cover plate 2011 is provided at the front end of the node connection fastener 201 . The cover plate 2011 can prevent the active layer 102 located at the uppermost layer or the lowermost layer from being separated from the node connection fastener 201 .

[0041] Specifically, the cover plate 2011 and the pressing block 2012 are both provided with through holes 2013, and the hinge shaft 202 is located in the through hole 2013. After the two node connecting fasteners 201 are snapped together, the through holes 2013 thereon will also be aligned. At this time, the hinge shaft 202 is inserted into the through hole 2013 to connect the two node connecting fasteners 201 into an integral structure to form a connecting node 2.

[0042] Specifically, the front end of the hinge shaft 202 is provided with an anti-slip component 2022, and the outer surface of the hinge shaft 202 is provided with a plurality of conical rings 2021. The anti-slip component 2022 prevents the hinge shaft 202 from directly passing through the through hole 2013 and falling off when being inserted into the through hole 2013, resulting in separation from the node connecting fastener 201. The conical ring 2021 is a structure that is wide at the top and narrow at the bottom. In the process of inserting the hinge shaft 202 into the through hole 2013 from top to bottom, the clamping force will be increased by the conical ring 2021, so that the hinge shaft 202 will automatically engage and be fixed in the through hole 2013, thereby increasing the clamping force and preventing it from falling off.

[0043] Specifically, the two node connecting fasteners 201 are arranged upside down. Through the node connecting fasteners 201 arranged upside down, the pressure block 2012 and the pressure groove 2014 thereon will be exactly aligned, which is convenient for personnel to perform the locking operation and form a complete cylindrical shape after locking, thereby improving the overall stability. At the same time, when a node connecting fastener 201 is damaged, it can also be easily replaced, thereby reducing the production and use costs.

[0044] Specifically, both sides of the sheet 1 are provided with embossing, and the side wall of the node connection fastener 201 is provided with threads, as shown in the attached Figure 5 As shown, the embossing is a stripe pattern, which increases the friction and bonding force between the sheet and the filler at a later stage. The thread will increase the rigidity and strength of the node and the friction between the sheet and the filler when the filler is filled in later.

[0045] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that Figure 6 As shown, the embossing is a wave pattern, which increases the friction and bonding force between the sheet and the filler in the later stage.

[0046] As attached Figure 7 As shown:

[0047] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that a manufacturing process of a geocell includes:

[0048] S1, a plurality of horizontal split seams 101 are provided on the sheet 1 to form an active layer 102 located above and below the split seams 101;

[0049] S2, dividing a plurality of active layers 102 into two groups in an interlaced manner, and pulling the two groups of active layers 102 toward two sides of the sheet 1 respectively;

[0050] S3, turning the two node connection fasteners 201 upside down, and then pushing the two groups of active layers 102 into the pressing grooves 2014 of the two node connection fasteners 201 respectively;

[0051] S4, engaging the pressing blocks 2012 and the pressing grooves 2014 of the two node connection fasteners 201 with each other, so that the active layer 102 is squeezed between the pressing blocks 2012 and the pressing grooves 2014;

[0052] S5. Insert the hinge shaft 202 into the through hole 2013 to connect the two node connection fasteners 201 to form a connection node 2, and form a mesh geocell by arranging the connection nodes 2 equidistantly in the longitudinal and transverse directions.

[0053] Specifically, in step S1 , a plurality of dividing seams 101 are aligned vertically.
