Description

Technical Field

[0001] The utility model relates to the technical field of geocells, in particular to a node connection auxiliary device for geocell construction. Background Art

[0002] Geocells are a new type of geosynthetics. They are flexible and can be folded or rolled up for transportation. When in use, they can be stretched to form a mesh-like cell structure. The cells can then be filled with materials such as sand, soil, or concrete, creating a structure with strong lateral restraint and high rigidity. They can be used as cushioning to improve the bearing capacity of weak foundations or laid on slopes to form slope protection structures. They are currently widely used in shallow foundation treatment, slope erosion control, and large-scale urban pipeline support projects, making them a promising foundation construction material.

[0003] However, the size of a single geocell product is limited (referring to the size that a single geocell product can cover after being stretched into a mesh shape. The geocell products in the industry are usually 50m 2 / piece), when facing large-area ground construction, in order to enhance the strength and integrity of the entire geocell paving layer, it is necessary to connect the two adjacent geocell products into a whole, thereby avoiding the formation of mechanically weak joints in the geocell paving layer.

[0004] Among the various node connection forms of geocells, the connection forms that are convenient for connecting two adjacent geocell products at the construction site are mainly U-shaped buckle connection (such as the U-shaped plug-in connection geocell disclosed in Chinese patent document CN202221432165.2) and snap-fit ​​node connection (such as the fastener node geocell disclosed in Chinese patent document CN202520459884.0). However, when facing large-scale ground construction of geocells, the connection between two adjacent geocell products is usually completed manually, which is labor-intensive and has poor consistency in the strength of the points connected by manual connection. In addition, there is also a form of inserting steel drills into the soil below to constrain the displacement of the geocell (that is, inserting a limiting rod into the soil below at the edge of each geocell product after it is laid out), but this also requires greater labor intensity, and the exposed rod ends are easy to cause harm to walking construction workers.

[0006] The utility model provides a node connection auxiliary device for geocell construction, which includes a frame, a slider and a base; the slider is slidably connected to the frame; the base is fixedly connected to the frame and is located on the sliding path of the slider; a first mounting groove is provided on the surface of the base facing the slider, and a second mounting groove is provided on the surface of the slider facing the base; the first mounting groove is used to install a first fastener of a fastener-node-type geocell, and the second mounting groove is used to install a second fastener of the fastener-node-type geocell; during the sliding process of the slider toward the base, the first fastener and the second fastener can be fastened toward each other.

[0007] Furthermore, the node connection auxiliary device can be used to connect two adjacent geocell products at the geocell construction site, and the connection work is carried out based on the targeted designed node connection auxiliary device.

[0012] However, after the slider is pushed by the tail end of the adjusting bolt, when connecting the next section to be connected, the slider needs to be slid in a direction away from the base, and this process requires manual operation.

[0013] Optionally, the node connection auxiliary device for geocell construction further includes an adjusting bolt; the axial direction of the adjusting bolt is parallel to the sliding path and is threadedly connected to the frame, and the tail of the adjusting bolt is rotatably connected to the slider.

DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the following examples and accompanying drawings. The exemplary embodiments and descriptions of the present invention are intended only to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the stage of actual development and use.

[0034] Geocells are a new type of geosynthetics. They are flexible and can be folded or rolled up for transportation. When in use, they can be stretched to form a mesh-like cell structure. The cells can then be filled with materials such as sand, soil, or concrete, creating a structure with strong lateral restraint and high rigidity. They can be used as cushioning to improve the bearing capacity of weak foundations or laid on slopes to form slope protection structures. They are currently widely used in shallow foundation treatment, slope erosion control, and large-scale urban pipeline support projects, making them a promising foundation construction material.

[0035] However, the size of a single geocell product is limited (referring to the size that a single geocell product can cover after being stretched into a mesh shape. The geocell products in the industry are usually 50m 2 / piece), when facing large-area ground construction, in order to enhance the strength and integrity of the entire geocell paving layer, it is necessary to connect the two adjacent geocell products into a whole, thereby avoiding the formation of mechanically weak joints in the geocell paving layer.

[0036] Among the various node connection forms of geocells, the node connection forms that are convenient for connecting two adjacent geocell products at the construction site are mainly U-shaped buckle connections (such as the U-shaped plug-in connection geocell disclosed in Chinese patent document CN202221432165.2) and snap-fit ​​node connector connections (such as the fastener node geocell disclosed in Chinese patent document CN202520459884.0). However, when facing large-scale ground construction of geocells, the connection between two adjacent geocell products is usually completed manually, which is labor-intensive and has poor consistency in the strength of the points connected by manual connection. In addition, there is also a form of restricting the displacement of the geocell by inserting a steel bar into the soil below (that is, inserting a limiting rod into the soil below at the edge of each geocell product after it is laid out), but this also requires greater labor intensity, and the exposed rod ends are easy to cause harm to walking construction workers.

[0037] To this end, the utility model proposes an auxiliary device that facilitates the connection of two adjacent geocell finished products at the construction site, which can assist manual work in completing the connection of two adjacent geocell finished products at the geocell construction site, and the mechanical strength consistency of the formed connection points is high.

[0038] Example 1:

[0039] like Figures 1 to 4 As shown, this embodiment provides a node connection auxiliary device for geocell construction, including a frame 1, a slider 2 and a base 3;

[0040] The slider 2 is slidably connected to the frame 1;

[0041] The support platform 3 is fixedly connected to the frame 1 and is located on the sliding path of the slider 2;

[0042] A first mounting groove 31 is provided on the surface of the support platform 3 facing the slider 2, and a second mounting groove 21 is provided on the surface of the slider 2 facing the support platform 3;

[0043] The first installation groove 31 is used to install the first fastener 41 of the fastener node type geocell, and the second installation groove 21 is used to install the second fastener 42 of the fastener node type geocell;

[0044] When the slider 2 slides toward the support platform 3 , the first fastener 41 and the second fastener 42 can be fastened toward each other.

[0045] Obviously, the node connection auxiliary device for geocell construction provided in this embodiment is a node connection auxiliary device proposed for the geocell node connection method connected by snap-fit ​​node connectors. It should be understood that after the first fastener 41 and the second fastener 42 are snapped together, a locking member needs to be applied to the two snapped together and then the two are taken out, thereby avoiding the failure of the snapping state of the two. Specifically, for example, in the geocell of the fastener node disclosed in Chinese patent document CN202520459884.0, the locking member is two plug rods. Then, the slider 2 is driven to slide away from the base 3, and the node formed after the first fastener 41 and the second fastener 42 are snapped together can be taken out, thereby completing the connection work of a node of the two adjacent geocell finished products.

[0046] More specifically, if Figure 3 、 Figure 4 As shown, a pin 22 is slidably provided on the side of the second mounting groove 21, and the direction of relative sliding between the two is perpendicular to the side;

[0047] One end of the pin 22 is spherical and faces the second mounting groove 21, and the other end is connected to the slider 2 via a spring 23; during the process of installing the second fastener 42 into the second mounting groove 21, the second fastener 42 abuts against the spherical surface of the pin 22 and pushes the pin 22 to slide toward the inside of the slider 2.

[0048] like Figure 1 As shown, the frame 1 is C-shaped, and the support 3 is located below the slider 2. A pin 22 is slidably provided on the side of the second mounting groove 21, so that after the second fastener 42 is installed in the second mounting groove 21, the second fastener 42 can be clamped in the second mounting groove 21 by the pushing force of the spring 23 (specifically, during the process of installing the second fastener 42 in the second mounting groove 21, the side of the second fastener 42 abuts against the spherical surface of the pin 22, thereby pushing the pin 22 to slide toward the inside of the slider 2. At the same time, the pin 22 compresses the spring 23. After the second fastener 42 is fully inserted into the second mounting groove 21, the elastic potential energy accumulated by the spring 23 pushes the pin 22 so that the pin 22 is pressed against the second fastener 42). This can prevent the second fastener 42 from falling out of the second mounting groove 21 in the "upside-down" state when the fastener node is connected using the node connection auxiliary device for geocell construction. After the first fastener 41 and the second fastener 42 are fastened together and locked, the second fastener 42 can be removed from the second mounting slot 21 by pulling the geocell belt. It should be understood that the difficulty of removing the second fastener 42 (i.e., the resistance to be overcome) mainly depends on the deformation of the spring 23 and the elastic coefficient of the spring 23 after the second fastener 42 pushes the pin 22 to compress the spring 23. More preferably, Figure 4As shown, in order to prevent the pin 22 from slipping out when no fastener is installed in the second mounting groove 21, a boss 221 is further provided on the side wall of the pin 22, and correspondingly, a limiting groove 211 is also provided on the side wall of the hole that cooperates with the pin 22.

[0049] Preferably, when the fastening of two fasteners requires the belt body to produce a break along the length direction (such as the fasteners used in the geocell with the fastener node disclosed in Chinese patent document CN202520459884.0), the section to be connected of the geocell belt body is cut to form at least two strips (this cutting operation has been completed in the early production process of the geocell product), and the width of the strip corresponds to the width of each protrusion 5111 on the fastener.

[0050] Furthermore, the protrusions 5111 of the fasteners can be directly used to push each strip into a preset shape (the shape of the alternating protrusions 5111 of each strip on the front and back sides of the geocell strip body) through the fastening action of the first fasteners 41 and the second fasteners 42, thereby avoiding the need to tear the strip body to form strips by the shearing action of the fastener fastening, thereby avoiding the problem of the fasteners being crushed due to forced shearing through the fastening action (fasteners are usually made of plastic, and forced shearing of the geocell strip body through the fastening action can easily cause the fasteners to be crushed).

[0051] More preferably, positioning holes are provided at both ends of the section to be connected along the length direction of the geocell strip, and positioning rods 32 matching the positioning holes are fixedly provided on the base 3 .

[0052] Furthermore, by aligning the positioning holes in the section to be connected with the positioning rods 32, the protrusions 5111 on the fasteners can be aligned with the strips on the strip, ensuring that the first and second fasteners 41, 42 engage without shearing the strip. It should be understood that the engagement of the first and second fasteners 41, 42 causes the strips in the section to be connected to bend (corresponding to the shape of the protrusions 5111 on the fasteners), pulling the geocell strips inward of the fasteners. To this end, the positioning holes in the section to be connected are elongated, with their length coinciding with the length of the strip.

[0053] Preferably, a limiting portion 26 is fixedly connected to the slider 2, and when the slider 2 slides toward the support platform 3, the limiting portion 26 can abut against the frame 1;

[0054] The limiting portion 26 is used to limit the minimum distance between the slider 2 and the support platform 3 when the slider 2 slides toward the support platform 3.

[0055] Thus, when the limiting portion 26 abuts the frame 1, a gap of a predetermined thickness exists between the first fastener 41 and the second fastener 42. This prevents the slider 2 from sliding too far toward the platform 3, which could damage the first fastener 41 and / or the second fastener 42. Furthermore, the limiting portion 26 precisely limits the sliding distance of the slider 2 toward the platform 3, thereby ensuring proper engagement of the two fasteners.

[0056] Example 2:

[0057] like Figures 5 to 7 As shown, this embodiment is based on embodiment 1, except that, in this embodiment:

[0058] The first mounting groove 31 is used to mount a first shaping member 51, and the first shaping member 51 is fixedly connected to the first mounting groove 31; the second mounting groove 21 is used to mount a second shaping member 52, and the second shaping member 52 is fixedly connected to the second mounting groove 21;

[0059] Any direction perpendicular to the sliding path is identified as a first direction; a first shaping portion 511 is formed on the surface of the first shaping member 51 facing the slider 2. The first shaping portion 511 includes at least one protrusion 5111 and one recess 5112, and the protrusion 5111 and the recess 5112 are adjacent to each other in the first direction (obviously, the number of protrusions 5111 and the number of recesses 5112 are equal or the difference is 1);

[0060] A second shaping portion that can be engaged with the first shaping portion 511 is processed on the surface of the second shaping member 52 facing the support platform 3;

[0061] When the slider 2 slides toward the support platform 3 , the first shaping portion 511 and the second shaping portion can squeeze the section to be connected therebetween into a shape that fits the shape of the first shaping portion 511 .

[0062] Clearly, the node connection auxiliary device for geocell construction provided in this embodiment is a node connection auxiliary device designed specifically for geocell node connection methods using U-shaped buckles. It should be understood that when this node connection auxiliary device for geocell construction is used to connect two adjacent finished geocells, the first direction coincides with the width direction of the geocell strip. After the first shaping portion 511 and the second shaping portion are engaged with each other, the section of the geocell strip to be connected is extruded into a shape that conforms to the first shaping portion 511 (i.e., the geocell strip forms a shape with alternating protrusions 5111 on the front and back of the strip in the width direction). Subsequently, one rod of the U-shaped buckle is inserted into the hole formed along the width direction of the geocell strip by the alternating protrusions 5111, forming a connection node. (The anti-slip structure and method of the U-shaped buckle are prior art and will not be further described.) Accordingly, since after the U-shaped buckle is inserted, a portion of the open end of the U-shaped buckle usually needs to be exposed for installing the anti-drop buckle, an avoidance hole 14 (used to accommodate the open end of the U-shaped buckle after the U-shaped buckle is inserted) should be provided on the bracket 12 to ensure that the U-shaped buckle is smoothly inserted.

[0063] Accordingly, the node connection auxiliary device for geocell construction provided in this embodiment can be used at the geocell construction site. By placing the to-be-connected sections of the belt bodies of two adjacent geocell finished products between the first shaping part 511 and the second shaping part, the slider 2 is driven to slide toward the base 3, and the to-be-connected sections are squeezed into a shape that fits the first shaping part 511, thereby facilitating the insertion of the U-shaped buckle to achieve the connection between the two adjacent geocell finished products.

[0064] Preferably, if Figure 6 As shown, a through groove 5113 is formed along the first direction on the protrusion 5111 of the first shaping portion 511 and the second shaping portion.

[0065] Furthermore, when the first shaping member 51 and the second shaping member 52 are engaged with each other, an insertion rod of the U-shaped buckle is inserted into the cutting groove 5113 along the first direction, thereby completing the operation of inserting a rod portion of the U-shaped buckle into the hole formed by the alternating protrusions 5111 along the width direction of the geocell belt body, thereby avoiding deformation of the sections to be connected or separation of the two sections to be connected after the two shaped sections to be connected are taken out.

[0066] Preferably, the direction perpendicular to the sliding path and perpendicular to the first direction is identified as the second direction, and a third shaping portion (i.e. Figure 6, the portion on the right side of the first shaping portion 511 indicated by the dotted box), the third shaping portion is adjacent to the first shaping portion 511 in the second direction; the third shaping portion is configured to have recesses 5112 corresponding one-to-one with the protrusions 5111 on the first shaping portion 511, and to have protrusions 5111 corresponding one-to-one with the recesses 5112 on the first shaping portion 511; the positions of the protrusions 5111 on the first shaping portion 511 are aligned with the positions of the corresponding recesses 5112 on the third shaping portion in the first direction;

[0067] Correspondingly, a fourth shaping portion capable of interlocking with the third shaping portion is formed on the surface of the second shaping member 52 facing the support platform 3. A through groove 5113 is formed on the protrusions 5111 of the third and fourth shaping portions along the first direction.

[0068] Thus, after the section of the geocell belt to be connected is squeezed toward each other by the first shaping member 51 and the second shaping member 52, it forms a shape that fits the first shaping portion 511 and the third shaping portion, and then the two rods of the U-shaped buckle can be respectively inserted into a hole along the width direction of the geocell (i.e., the groove 5113 of the first shaping portion 511 and the groove 5113 of the third shaping portion) to form a connection node.

[0069] Obviously, in this embodiment, the first shaping member 51 and the second shaping member 52 are reused multiple times (in Example 1, because the first fastener 41 and the second fastener 42 are both components of the node, the first fastener 41 and the second fastener 42 need to be installed once each time a node is formed). Therefore, in this embodiment, the first shaping member 51 and the second shaping member 52 are both made of wear-resistant and rust-resistant metal materials (such as high-speed steel and high-manganese steel). Furthermore, when the geocell node connection work of the U-shaped buckle connection is performed using the node connection auxiliary device for geocell construction provided by this embodiment, the section to be connected does not need to be pre-cut to form a strip. At this time, when the driving slider 2 slides toward the base 3 so that the first shaping member 51 and the second shaping member 52 engage with each other, the section to be connected can also be cut into a strip by shearing.

[0070] It should be understood that since the first shaping part 51 and the second shaping part 52 are both made of wear-resistant and rust-proof metal materials, in this embodiment, the main purpose of providing the limiting portion 26 is that when the limiting portion 26 abuts against the frame 1, there is a gap of preset thickness between the first shaping part 511 and the second shaping part (when a third shaping part and a fourth shaping part are provided, there is also a gap of preset thickness between the two), thereby preventing the slider 2 from sliding too far toward the base 3, causing the section to be connected to be crushed (such as the skin being crushed, the belt being flattened, etc.), thereby reducing the tensile strength of the section to be connected.

[0071] Obviously, in this embodiment, the section to be connected may also be pre-cut to form at least two strips (the number of strips is equal to the sum of the number of protrusions 5111 and the number of recesses 5112 on the first shaping portion 511, and this cutting operation is completed in the early stage of the geocell production process), and the width of the strip corresponds to the width of each protrusion 5111 on the first shaping member 51. Positioning holes are formed at both ends of the section to be connected along the length direction, and positioning rods 32 that match the positioning holes are fixedly provided on the base 3 (the reason why the positioning holes should be elongated has been explained in the previous content and will not be repeated here).

[0072] Furthermore, when the slider 2 moves toward the platform 3 , the first shaping member 51 and the second shaping member 52 do not need to shear the connecting section, thereby reducing the force required to drive the slider 2 and achieving the purpose of reducing manual labor intensity.

[0073] Example 3:

[0074] like Figure 1 、 Figure 2 As shown, this embodiment is based on embodiment 1 or embodiment 2, except that, in this embodiment:

[0075] The node connection auxiliary device for geocell construction also includes an adjusting bolt 61;

[0076] The axial direction of the adjusting bolt 61 is parallel to the sliding path and is threadedly connected to the frame 1 . The tail end of the adjusting bolt 61 abuts against a side of the sliding block 2 away from the support platform 3 .

[0077] Then, by rotating the adjusting bolt 61, the slider 2 can be driven to slide toward the base 3, and after the second shaping member 52 contacts the section to be connected below (the section to be connected is usually placed on the first shaping member 51 below), sufficient extrusion effect is provided to achieve the shaping of the section to be connected.

[0078] Specifically, the present application does not limit the shape of the head of the adjusting bolt 61, but preferably, when the head of the adjusting bolt 61 is cylindrical (such as a hexagonal head), a knurling 62 (such as a hexagonal head) is provided on the outer peripheral wall of the head. Figure 1 The knurling 62 facilitates the quick manual rotation of the adjusting bolt 61 until the second shaping member 52 contacts the lower section to be connected.

[0079] In another specific practice of this embodiment, the node connection auxiliary device for geocell construction further includes an adjusting bolt 61;

[0080] The axial direction of the adjusting bolt 61 is parallel to the sliding path and is threadedly connected to the frame body 1 , and the tail of the adjusting bolt 61 is rotatably connected to the slider 2 .

[0081] Specifically, if Figure 2 As shown, a ring groove is formed at the tail end of the adjusting bolt 61, and a corresponding raised ring is provided on the slider 2, thereby limiting the relative movement of the adjusting bolt 61 and the slider 2 in the axial direction of the screw. Accordingly, by rotating the adjusting bolt 61, the slider 2 can be driven toward the base 3, and by rotating the adjusting bolt 61 in the opposite direction, the slider 2 can be driven away from the base 3.

[0082] Example 4:

[0083] like Figure 5 、 Figure 7 As shown, this embodiment is based on embodiment 1 or embodiment 2, except that, in this embodiment:

[0084] A pull rod 24 is fixedly connected to the slider 2, and a through hole 25 is opened on the pull rod 24; a support rod 11 is fixedly provided on the frame 1;

[0085] The node connection auxiliary device further includes a lever 71 , a middle portion of the lever 71 is hinged to the support rod 11 , and one end of the lever 71 is inserted into the through hole 25 .

[0086] Accordingly, the node connection auxiliary device for geocell construction provided in this embodiment can slide the slider 2 toward the base 3 by lifting the lever 71 away from one end of the pull rod 24, and can move the slider 2 away from the base 3 by pressing down the end away from the pull rod 24. It is worth noting that by adjusting the rod length ratio of the lever 71 at both ends of the support rod 11, the purpose of labor saving can be achieved based on the principle of the lever 71. It should be understood that the through hole 25 is a bar-shaped hole, and thus when the lever 71 is lifted or pressed away from one end of the pull rod 24, the portion of the lever 71 located within the through hole 25 can have room to swing.

[0087] Example 5:

[0088] like Figure 8 As shown, this embodiment is based on embodiment 3 or embodiment 4, except that, in this embodiment:

[0089] A bracket 12 is further extended below the frame body 1 , and a plate-shaped footrest portion 13 is provided at the bottom of the bracket 12 , wherein the plate surface of the footrest portion 13 is perpendicular to the sliding path.

[0090] Since the node connection auxiliary device for geocell construction is relatively small in size, the node connection auxiliary device for geocell construction is easily shaken when the frame 1 is grasped by hand to rotate the adjusting bolt 61 or operate the lever 71; by providing the foot pedal 13, at the geocell construction site, the operator can fix the frame 1 by stepping on the foot pedal 13, thereby facilitating the rotation of the adjusting bolt 61 or the operation of the lever 71, thereby reducing the difficulty of a single person operating the node connection auxiliary device for geocell construction.

[0091] In this application, the term "rotational connection" means that the two can only rotate relative to each other. For example, the rotation setting of the hole and the shaft rod can achieve the limitation of axial relative movement by setting a shoulder on the shaft and a limit groove in the hole, or by setting a convex ring in the hole and a corresponding annular groove on the shaft rod; the term "sliding connection" and "sliding setting" mean that the two can only slide relative to each other, such as dovetail grooves, T-slots and other structures.

[0092] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
