A weaving method for high-strength three-dimensional composite geogrid

Abstract

A method for weaving a high-strength three-dimensional composite geogrid includes primary processing of the geogrid, secondary processing of the geogrid, and winding of the finished product. The geogrid processed by the above weaving method has a double-layer structure. The double-layer geogrid can be neatly housed by the winding unit. During the winding process, the springs of the adjusting member can be inserted into the mesh of the geogrid, ensuring that the setting of the adjusting member does not affect the winding of the finished geogrid. When using the geogrid, it only needs to be laid once. By fixing the lower layer of geogrid, the upper layer of geogrid is lifted up so that the upper connecting member is elastically snapped into the slot on the outside of the two springs. The adjusting member can complete the support work of the double-layer geogrid, making the laying of the geogrid simpler and faster, and ensuring the soil stabilization and slope protection effect of the geogrid.

Description

Technical Field

[0001] This invention relates to the field of fiberglass geogrid processing technology, specifically a weaving method for a high-strength three-dimensional composite geogrid. Background Technology

[0002] Geogrids are commonly used soil stabilization and slope protection materials in construction, road and other projects. Currently, in order to ensure the tensile strength of geogrids, reduce their elongation, and at the same time ensure the thermal stability of geogrids and their compatibility with asphalt in road soil stabilization construction, geogrids are often made of alkali-free untwisted glass fiber roving as the main raw material, and are made into a mesh structure material using a certain weaving process. After special coating treatment, they are formed into a new type of excellent geotextile substrate.

[0003] However, the geogrid produced by this method is usually a two-dimensional mesh structure. However, the soil stabilization and slope protection effect of this two-dimensional mesh structure of fiberglass geogrid still has certain limitations. Therefore, when using it, two layers of fiberglass geogrid are usually laid and support members are fixed between the two layers of fiberglass geogrid so that the double-layer fiberglass geogrid as a whole completes the soil stabilization and slope protection work in a three-dimensional shape. This construction method requires a lot of construction time when laying fiberglass geogrid and installing support members, resulting in certain shortcomings in the use of fiberglass geogrid. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention provides a weaving method for a high-strength three-dimensional composite geogrid.

[0005] The technical solution of this invention is as follows:

[0006] A weaving method for a high-strength three-dimensional composite geogrid, based on a weaving system, the weaving system including a control unit and a communication connection thereof, and sequentially arranged a weaving unit, a transfer unit, a secondary processing unit, and a winding unit, the weaving method specifically including the following steps:

[0007] S1: Primary processing of the bar grid;

[0008] S1.1 The control unit controls the weaving unit to weave the grid mesh;

[0009] The weaving unit includes two warp knitting machines arranged sequentially, each capable of independently completing the weaving of fiberglass grid mesh;

[0010] S1.2, The transfer unit operates to wind up the grid mesh;

[0011] The transfer unit includes two sets of winding devices arranged vertically, and the two sets of winding devices can be used to wind up the grid mesh woven by the two warp knitting machines respectively.

[0012] S2: Secondary processing of the bar grid;

[0013] The grid mesh on the two winding devices is transported to the secondary processing unit, where it undergoes secondary processing.

[0014] The secondary processing unit includes a connector mounting device and an adjuster mounting device arranged sequentially from front to back. The connector mounting device includes two sets of first mounting modules arranged vertically, and the adjuster mounting device includes a second mounting module.

[0015] Based on the above structure, the specific steps of the secondary processing are as follows:

[0016] S2.1 Installation of connectors;

[0017] The grid mesh on the two sets of winding devices is divided into upper and lower layers and passes through two sets of first installation modules respectively. The installation of the connecting parts on the upper and lower layers of grid mesh is completed by the two sets of first installation modules respectively.

[0018] The connector includes an upper connector and a lower connector with a sheet-like structure. The upper connector has a round opening in the middle. The first installation module can fix the upper connector and the lower connector at the intersection of the upper and lower grid meshes respectively. The upper side of the first installation module is also provided with a punching module on one side along the transport direction of the grid mesh.

[0019] S2.2 The punching module operates to punch holes in the upper grid mesh at the positions corresponding to the circular openings of the upper connectors;

[0020] S2.3 Installation of adjusting components;

[0021] The upper and lower grid meshes are fitted together, and the upper and lower connecting parts are in one-to-one correspondence. The second installation module is used to install the adjusting parts between the two grid meshes.

[0022] The adjusting component includes a pin with an outer diameter not greater than the diameter of the circular opening, and two springs with their ends spaced apart. The outer side of the springs away from the pin is provided with a slot that can accommodate the upper connector. The second mounting module can pass the end of the pin away from the springs downward through the circular opening of the upper connector and fix it to the lower connector.

[0023] S3, the winding unit works to complete the winding of the finished geogrid.

[0024] The geogrid produced by the above weaving method has a double-layer structure. The double-layer geogrid can be neatly housed by the winding unit. During the winding process, the spring clips of the adjusting component can be inserted into the mesh of the geogrid, ensuring that the setting of the adjusting component does not affect the winding of the finished geogrid. When using the geogrid, it only needs to be laid once. By fixing the lower layer of geogrid, the upper layer of geogrid is lifted up so that the upper connector can be elastically snapped into the slots on the outside of the two spring clips. The adjusting component can complete the support work of the double-layer geogrid, making the laying of the geogrid simpler and faster, and ensuring the soil stabilization and slope protection effect of the geogrid.

[0025] In the above-described method for weaving a high-strength three-dimensional composite geogrid, in step S1.1, a guide device is provided between the two warp knitting machines and the winding device. The geogrid processed by the two warp knitting machines can bypass the two guide devices and complete the winding work through the transfer unit, so that the winding work of the winding device and the warp knitting processing work of the two warp knitting machines will not interfere with each other, and at the same time ensure that the geogrid can be tightly wound on the winding device.

[0026] In a preferred embodiment of the present invention, in step S1.2, the winding device includes a reversing module and several sets of winding modules disposed thereon. The several sets of winding modules can alternately complete the winding work of the grid mesh under the action of the reversing module. Based on this structure, the winding work of the grid mesh of the winding device will not interfere with the subsequent secondary processing work, ensuring that the winding work of the grid mesh on the winding device and the secondary processing work of the grid mesh on the winding device can be carried out separately.

[0027] In the weaving method of a high-strength three-dimensional composite geogrid described above, in step S2.1, the upper connector includes a sheet-like upper pressure plate and an upper support plate with an opening in the middle, and the lower connector includes a sheet-like lower pressure plate and a lower support plate. A snap-fit ​​structure is provided between the upper pressure plate and the upper support plate, and between the lower pressure plate and the lower support plate, for mutual engagement. The first installation module is configured to snap-fit ​​and clamp the upper pressure plate and the upper support plate, as well as the lower pressure plate and the lower support plate, onto the upper and lower sides of the upper and lower geogrids respectively, making the connection between the upper connector, the lower connector, and the geogrid more secure and reliable.

[0028] In a preferred embodiment, in step S2.3, a threaded cylinder is provided in the middle of the side of the lower pressure plate away from the lower support plate. The second mounting module can connect the end of the pin away from the spring to the threaded cylinder in a spiral manner, so that the installation of the adjusting part and the lower connecting part can be more convenient and reliable.

[0029] In the weaving method of the high-strength three-dimensional composite geogrid described above, in step S2.1, the connector installation device further includes a first guide module corresponding to the grid entry side and grid exit side of the first installation module. The geogrid can pass horizontally through the first installation module under the action of the first guide module, ensuring that the connector can be accurately installed at the intersection position of the geogrid under the action of the first installation module.

[0030] In a preferred embodiment, in step S2.1, the first guide module includes two second guide rollers arranged vertically opposite each other, and one of the second guide rollers is elastically arranged vertically so that the two second guide rollers can better clamp the grid mesh and complete the guiding work of the grid mesh.

[0031] As a further preferred embodiment, in step S2.1, the height of the second guide roller shaft, which is not vertically elastically set in the first guide module, is adjustable. This setting allows the height of the grid mesh or the clamping force between the two second guide roller shafts to be adjusted, further ensuring the effectiveness of the first guide module.

[0032] In the weaving method of the high-strength three-dimensional composite geogrid described above, in step S2.3, the adjusting component installation device further includes a second guide module corresponding to the grid entry side of the second installation module. The second guide module includes two third guide rollers arranged opposite each other. The two layers of geogrid can pass through the second installation module in a close fit under the action of the two third guide rollers, so that the adjusting component can smoothly pass through the upper connecting component and be spirally connected to the lower connecting component under the action of the second installation module.

[0033] In a preferred embodiment, in step S2.3, a second guide module is also provided at the position corresponding to the grid exit side of the second installation module, and the third guide roller of the second guide module on this side is provided with an avoidance groove on the outer ring corresponding to the position of the adjustment member, which can accommodate the adjustment member to pass through, so as to ensure that the processed geogrid can be tightly fitted and completed by the winding unit to complete the winding work.

[0034] The beneficial effects of this invention are as follows: This invention provides a weaving method for a high-strength three-dimensional composite geogrid, including a primary processing step, a secondary processing step, and a winding step for the finished product. The geogrid processed by the above weaving method has a double-layer structure. The double-layer geogrid can be neatly housed by the winding unit, and during the winding process, the springs of the adjusting member can be inserted into the mesh of the geogrid, ensuring that the setting of the adjusting member does not affect the winding of the finished geogrid. When using the geogrid, it only needs to be laid once. By fixing the lower layer of geogrid, the upper layer of geogrid is lifted up so that the upper connecting member is elastically inserted into the slot on the outside of the two springs. The double-layer geogrid can be supported by the adjusting member, making the laying of the geogrid simpler and faster, and ensuring the soil stabilization and slope protection effect of the geogrid.

The grid mesh 5 processed by the two warp knitting machines 11 can bypass the two guide devices 12 respectively and complete the winding work through the transfer unit 2, so that the winding work of the winding device 22 will not interfere with the warp knitting work of the two warp knitting machines 11, and at the same time ensure that the grid mesh 5 can be tightly wound on the winding device 22.

[0055] Specifically, the structure of the guiding device 12 includes a guiding bracket and a first guiding roller shaft horizontally arranged on it. The grid 5 is arranged around the upper / lower side of the first guiding roller shaft, and the grid 5 between the first guiding roller shaft and its corresponding warp knitting machine 11 is horizontal, ensuring that the winding operation of the winding device 22 and the warp knitting operation of the warp knitting machine 11 will not interfere with each other.

The several sets of winding modules 222 can alternately complete the winding work of the grid mesh 5 under the action of the reversing module 221. Based on this structure, the winding work of the grid mesh 5 of the winding device 22 will not interfere with the subsequent secondary processing work, ensuring that the winding work of the grid mesh 5 on the winding device 22 and the secondary processing work of the grid mesh 5 on the winding device 22 can be carried out separately.

[0057] Specifically, regarding the structure of the reversing module 221 and the winding module 222, the reversing module 221 includes two reversing disks 2211 arranged opposite to each other, and the two reversing disks 2211 are rotatably connected to the transfer frame 21.

A spring 3143 is provided between the side of the connecting block 3142 away from the other second guide roller 3141 and the first bracket 311, so that the two second guide rollers 3141 can clamp the grid mesh 5 well and complete the guiding work of the grid mesh 5.

[0066] Preferably, the height of the second guide roller 3141, which is not vertically elastically set in the first guide module 314, is adjustable.

An insert plate is provided in the adsorption port at the position corresponding to the gap between the two springs 72. The adjustment component installation device 32 also includes an adjustment component 7 conveying line provided with the second fixing component corresponding to the second installation module 322. The adjustment component 7 can be transported vertically along the adjustment component 7 conveying line with the spring 72 pointing upward.

The adjustment component 7 can pass through the round opening in the middle of the upper connecting component 61 from top to bottom and is spirally connected to the threaded cylinder on the lower pressure plate 621 of the lower connecting component 62 under the action of rotation.

[0073] Furthermore, in order to ensure that the adjusting component 7 can pass smoothly through the round opening of the connecting component 6 and be spirally connected to the threaded cylinder on the lower pressure plate 621 under the action of the second fixing component, the adjusting component mounting device 32 also includes a support platform 323 located on the lower side of the second mounting module 322 and capable of supporting the grid mesh 5.

[0077] In this embodiment, based on the above-described weaving system structure, the weaving method specifically includes the following steps:

[0078] S1: One-time processing of the grating mesh 5;

[0079] S1.1 The control unit controls the two warp knitting machines 11 of the weaving unit 1 to work and weave the grid mesh 5;

[0080] S1.2, Transfer unit 2 operates to wind up the grid mesh 5;

[0081] The grid mesh 5, processed by the two warp knitting machines 11, passes around the two first guide devices 12 respectively, and the two winding devices 22 of the transfer unit 2 complete the winding of the grid mesh 5.

[0082] Furthermore, in this step, if one of the winding modules 222 of the winding device 22 completes the winding work, and the secondary processing work of the grid mesh 5 on the other winding modules 222 is completed, the reversing module 221 will change the position of the winding module 222, so that the winding work and the subsequent secondary processing work can operate without interference.

[0083] S2: Secondary processing of grating mesh 5;

[0084] The grid mesh 5 on the two winding devices 22 is transported to the secondary processing unit 3, and the secondary processing unit 3 performs secondary processing on the grid mesh 5.

[0085] The specific steps are as follows:

[0086] S2.1 Installation of connector 6;

[0087] The grid mesh 5 on the two sets of winding devices 22 passes through the two sets of first installation modules 313 in an upper and lower layer, and the first fixing components of the two sets of first installation modules 313 respectively complete the installation of the connectors 61 on the upper and lower layers of grid mesh 5.

[0088] S2.2 The punching module operates to punch holes in the upper grid 5 at the positions corresponding to the circular openings of the upper connector 61;

[0089] S2.3 Installation of adjusting component 7;

[0090] The upper and lower grid meshes 5 are fitted together, and the upper connector 61 and the lower connector 62 are in a one-to-one correspondence. The installation of the adjusting member 7 between the two grid meshes 5 is completed through the second fixing component of the second installation module 322.

[0091] S3, the winding unit 4, completes the winding of the finished geogrid.

[0092] The geogrid produced by the above weaving method has a double-layer structure. The double-layer geogrid 5 can be neatly housed by the winding unit 4. During housing, the spring 72 of the adjusting member 7 can be inserted into the mesh of the geogrid 5, so that the setting of the adjusting member 7 will not affect the winding of the finished geogrid. When using the geogrid, it only needs to be laid once. By fixing the lower geogrid 5, the upper geogrid 5 is lifted up so that the upper connecting member 61 is elastically inserted into the slot 721 on the outside of the two spring 72. The adjusting member 7 can complete the support work of the double-layer geogrid 5, making the laying of the geogrid simpler and faster, and ensuring the soil stabilization and slope protection effect of the geogrid.
