Technical Field

[0001] The invention relates to the technical field of glass fiber geogrid processing, in particular to a weaving method of a high-strength three-dimensional composite geogrid. Background Art

[0002] Geogrids are commonly used soil consolidation and slope protection equipment in construction, roads, etc. At present, 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 consolidation construction, the current geogrids often use glass fiber alkali-free untwisted roving as the main raw material, a mesh structure material made using a certain weaving process, and a new type of excellent geotechnical base material formed through a special coating treatment process.

[0003] However, the geogrid woven by this method is usually a two-dimensional mesh structure. However, the soil consolidation and slope protection effect of this two-dimensional mesh structure of fiberglass grid is still limited. Therefore, when in use, two layers of fiberglass grid are usually laid, and support members are fixed between the two layers of fiberglass grid to make the double-layer fiberglass grid three-dimensional as a whole to complete the soil consolidation and slope protection work. This construction method requires a lot of construction time when laying the fiberglass grid and installing the support members, resulting in certain deficiencies in the use of fiberglass grid. Summary of the invention

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a weaving method of a high-strength three-dimensional composite geogrid.

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

[0006] A weaving method for a high-strength three-dimensional composite geogrid is based on a weaving system, wherein the weaving system includes a control unit and a weaving unit, a transfer unit, a secondary processing unit and a winding unit which are connected to the control unit and are arranged in sequence. The weaving method specifically includes the following steps:

[0007] S1: One-time processing of the grille mesh;

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

[0009] Wherein, the weaving unit includes two warp knitting machines which are arranged in sequence and can independently complete the weaving work of the glass fiber grid mesh;

[0010] S1.2, the transfer unit works to roll up the grille mesh;

[0011] Wherein, the transfer unit includes two sets of winding devices arranged in an upper and lower manner, and the two sets of winding devices can be used for winding the grid mesh woven by two warp knitting machines respectively;

[0012] S2: Secondary processing of grid mesh;

[0013] The grille nets on the two winding devices are transported to the secondary processing unit, and the secondary processing of the grille net is carried out by the secondary processing unit;

[0014] Wherein, the secondary processing unit comprises a connecting piece installation device and an adjusting piece installation device which are sequentially arranged front and back, the connecting piece installation device comprises two groups of first installation modules arranged up and down, and the adjusting piece installation device comprises a second installation module;

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

[0016] S2.1, installation of connectors;

[0017] The grille nets on the two groups of winding devices are layered in upper and lower layers and pass through the two groups of first installation modules respectively, and the installation work of the connecting parts on the upper and lower layers of the grille nets is completed respectively through the two groups of first installation modules;

[0019] S2.2, the punching module works to punch holes at the positions of the upper grille mesh corresponding to the circular openings of the upper connecting pieces;

[0020] S2.3, installation of fixings;

[0021] The upper and lower layers of grille mesh are in close contact, and the upper connecting piece and the lower connecting piece are in one-to-one correspondence through the second installation module, and the installation of the adjustment piece between the two grille meshes is completed through the second installation module;

Through this setting, the height of the grille or the clamping force between the two second guide rollers can be adjusted, further ensuring the use effect of the first guide module.

[0081] The grid mesh 5 processed by the two warp knitting machines 11 passes through the two first guide devices 12 respectively, and the grid mesh 5 is rolled up by the two winding devices 22 of the transfer unit 2;

[0082] And 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 works to change the position of the winding module 222, so that the winding work and the subsequent secondary processing work can be performed without interfering with each other;

[0083] S2: secondary processing of the grid 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:

[0086] S2.1, installation of connector 6;

[0087] The grille nets 5 on the two groups of winding devices 22 are layered in upper and lower layers and pass through the two groups of first installation modules 313 respectively, and the installation work of the connecting members 61 on the upper and lower layers of the grille nets 5 is completed respectively through the first fixing components of the two groups of first installation modules 313;

[0091] S3, the rolling unit 4 works to complete the rolling of the geogrid product.

[0092] The geogrid processed by the above-mentioned weaving method has a double-layer structure. The double-layer grid net 5 can be stored in a fitting state by the winding unit 4, and the spring 72 of the adjusting member 7 can be inserted into the mesh of the grid net 5 during storage, so that the setting of the adjusting member 7 will not affect the winding of the geogrid product. When the geogrid is in use, it only needs to be laid once, and by fixing the lower grid net 5, the upper grid net 5 is lifted up so that the upper connecting member 61 is elastically inserted into the groove 721 on the outside of the two springs 72. The supporting work of the double-layer grid net 5 can be completed by the adjusting member 7, so that the laying work of the geogrid can be simpler and faster, thereby ensuring the soil consolidation and slope protection effect of the geogrid.
