Description
Technical Field
[0001] The utility model relates to the technical field of geocells, in particular to a plug-in geocell. Background Art
[0002] Geocell is a geotechnical reinforcement material with a honeycomb structure formed by strong connection of high-strength ribs. It is flexible and can be folded up during transportation. It can be opened and filled with soil, concrete or other fillers during use to form a structure with strong lateral restraint and rigidity. It can be used as a cushion to increase the bearing capacity of soft foundations, or it can be laid on the slope to form a slope protection structure, and it can also be used to build retaining structures, etc.
[0003] With the widespread application of geocells in the field of reinforcement, the adequacy of the expansion of plastic geocell grids is particularly important. Traditional cell node connection methods include welding, plug-in, riveting, mortise and tenon connection, bolt connection or injection molding connection, among which the node tensile strength of the plug-in plastic geocell is higher, but the disadvantage is that the peel strength and shear strength of the node are lower. The tensile strength of the plug-in geocell node is directly related to the parallelism of the plug-in rod. In existing projects, in order to prevent the plug-in from falling off from the node, the free ends of the U-shaped plug-in rod are generally welded together to prevent the plug-in from falling off and enhance the overall strength. However, the welding treatment method will reduce the parallelism of the plug-in rod, resulting in a serious decrease in the tensile strength of the node. In addition, in the process of laying the soil cell, it is necessary to repeatedly adjust the laying angle between the two adjacent reinforcement belts at the connection of the preset cell node, and the laying efficiency is low. At the same time, because the angle between the two adjacent reinforcement belts at the node is generally small, it is easy to appear backfill dead corner when filling the filler.
[0004] In view of this, it is necessary to design a plug-in geocell to solve the above problems. Utility Model Content
[0005] The utility model aims to provide a plug-in geocell which can improve the parallelism of the plug-in while ensuring the overall strength of the plug-in, and can also improve the peel strength and shear strength at the node, as well as improve the laying efficiency of the geocell and prevent the occurrence of backfill dead corners.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A plug-in geocell, comprising:
[0008] A rib belt, wherein a plurality of first interpenetrating areas are arranged at intervals along the vertical direction on the rib belt;
[0009] A plug-in having a closed end at one end and an open end at the other end;
[0010] An isolator is arranged between two adjacent ribs, and a second insertion area corresponding to the first insertion area is arranged on the isolator, so that the opening end of the plug-in alternately passes through the ribs, the isolator and the insertion area on another adjacent rib, so that the two adjacent ribs and the isolator are connected as a whole to form a node; the width of both ends of the isolator gradually increases in a direction away from the node;
[0011] A fixed cross bar is engaged and connected with the open end of the isolation member to prevent the plug-in from falling off the tendon strip;
[0012] The fixing piece is sleeved on the outside of the plug-in unit so that the part fixed by the plug-in unit is wrapped in the fixing piece.
[0013] As a further improvement of the present invention, the fixing member includes two detachably connected connecting blocks, and the two connecting blocks are connected to form a wrapping structure with openings on both sides.
[0014] As a further improvement of the present invention, along the extension direction of the rib strip, the size of the fixing piece is larger than the size of the plug-in piece.
[0015] As a further improvement of the utility model, the plug-in unit includes two parallel plug-in rods, one end of the two plug-in rods are connected by a connecting rod to form a plug-in structure with one end closed and the other end open.
[0016] As a further improvement of the present invention, a plug hole is provided on the fixed cross bar corresponding to the plug rod.
[0017] As a further improvement of the present invention, a limit block with a maximum diameter greater than the diameter of the plug rod is provided at one end of the plug rod away from the connecting rod. The limit block is variable in diameter under the action of external force, so that under the action of external force, the diameter of the limit block is reduced to a value smaller than the diameter of the insertion hole, presenting an installation state that is convenient for fixing the cross bar installation. In the natural state, the limit block is in a limited state to prevent the plug from falling off the rib belt.
[0018] As a further improvement of the present invention, the side of the isolating member close to the rib band is arc-shaped.
[0019] As a further improvement of the present invention, the penetration area is a through hole.

[0022] 2. The utility model sets isolation pieces between adjacent ribs at the nodes, the width of which gradually increases in the direction away from the nodes, and uses plug-ins to fix the ribs and isolation pieces. On the one hand, the isolation pieces can be used to enhance the shear strength at the nodes.

[0032] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
[0033] See also Figure 1-Figure 3As shown, the utility model provides a plug-in geocell, comprising:
[0034] A rib belt 10, wherein a plurality of first interpenetrating areas 11 are arranged at intervals along the vertical direction on the rib belt 10;
[0035] A plug-in having a closed end at one end and an open end at the other end;
[0036] The spacer 40 is arranged between two adjacent ribs 10, and the spacer 40 is provided with a second interpenetrating area 41 corresponding to the first interpenetrating area 11, so that the plug-in opening end staggers through the ribs 10, the spacer 40 and the interpenetrating area on another adjacent ribs 10, so that the two adjacent ribs 10 and the spacer 40 are connected as a whole to form a node; the width of the two ends of the spacer 40 gradually increases in the direction away from the node;
[0037] The fixed cross bar 30 is engaged with the open end of the isolation member 40 to prevent the plug-in from falling off the tendon band 10;
[0038] The fixing member 50 is sleeved on the outside of the plug-in unit so that the part fixed by the plug-in unit is wrapped in the fixing member 50 .
[0039] Specifically, the fixing member 50 includes two detachably connected connection blocks, and the two connection blocks are connected to form a wrapping structure with openings on both sides. Exemplarily, the two connection blocks are snap-fitted, one connection block is provided with a protrusion, and the other connection block is correspondingly provided with a groove. Through the cooperation of the protrusion and the groove, the two connection blocks are connected to form an integral structure and snapped on the outside of the plug-in, thereby using the fixing member 50 to improve the peel strength of the geocell node, and at the same time, it can also play a role in isolating the plug-in connection part of the node from the external environment to a certain extent, improving the anti-corrosion performance of the geocell node, and ensuring the long-term connection stability at the node.
[0040] Specifically, along the extension direction of the rib band 10 , the size of the fixing member 50 is larger than the size of the plug-in, and both sides of the opening of the fixing member 50 are respectively fitted with the rib band 10 , and the inner side of the fixing member 50 is fitted with the outer side of the plug-in.
[0041] Specifically, the side of the spacer 40 close to the ribs 10 is arc-shaped, so that the two sides of the spacer 40 can better fit with the ribs 10. The setting of the spacer 40 can, on the one hand, enhance the shear strength at the node, and on the other hand, the spacer 40 can be used as an angle preset member, so that when laying the geocell, a preset angle can be quickly formed between the two ribs 10 of the geocell, thereby improving the laying efficiency of the geogrid. At the same time, the presence of the spacer 40 can also prevent the backfill dead corner from appearing at the node.
[0042] Specifically, Figure 4As shown, the plug-in includes two parallel plug-in rods 21, and one end of the two plug-in rods 21 is connected by a connecting rod to form a plug-in structure with one end closed and the other end open.
[0043] Specifically, a plug hole 31 is provided on the fixed cross bar 30 corresponding to the plug rod 21 .
[0044] Specifically, a stopper 22 with a maximum diameter greater than the diameter of the plug rod 21 is provided at one end of the plug rod 21 away from the connecting rod. The stopper 22 is a variable diameter setting under the action of external force, so that under the action of external force, the diameter of the stopper 22 is reduced to less than the diameter of the insertion hole 31, presenting an installation state that is convenient for the installation of the fixed cross bar 30. In a natural state, the stopper 22 is in a limited state to prevent the plug from falling off the reinforcing band 10. Exemplarily, the stopper 22 includes two triangular structures arranged at intervals at the end of the plug rod 21, the bottom edge of the triangular structure is connected to the end of the plug rod 21, so that the two triangular structures together form a limit structure with a cross section gradually reduced in the direction away from the plug rod 21, and the triangular structure is made of a material with a certain degree of flexibility, so that under the action of external force, the two triangular structures are close to each other, so that the maximum diameter of the limit structure is reduced to less than the diameter of the insertion hole 31, at this time, the fixed cross bar 30 can be installed on the plug rod 21 through the limit structure; when the external force is removed, the two triangular structures return to the original state, presenting a limited state to prevent the plug from falling off the reinforcing band 10. The limit setting of the fixed cross bar 30 can maintain the parallelism of the two inserted rods 21 and improve the tensile strength of the geocell node.
[0045] Specifically, the insertion area is a through hole to facilitate the insertion of the insertion rod 21 .
[0046] Specifically, the isolating member 40 is made of a material with a certain toughness; the width of the middle portion of the isolating member 40 is relatively small, and there will be no problem of affecting the insertion of the plug-in.
[0047] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
