Description

Technical Field

[0001] The utility model relates to the technical field of composite geotextiles, in particular to a steel-plastic grid thermal composite geotextile. Background Art

[0002] Steel-plastic grating has high strength and is used in many scenarios. However, the disadvantage is that there are holes in the horizontal and vertical staggered arrangement of steel-plastic grating. The presence of holes will cause the above-mentioned steel-plastic grating to not have good barrier performance. Increasing the density of the steel-plastic grating belt can make it have better barrier ability, but the corresponding cost will increase, and after the density is increased, it will be more difficult to bend and wind it. Therefore, it is not reasonable to improve the barrier ability of steel-plastic grating by increasing the density of the grating belt. Utility Model Content

[0003] In order to solve the problem of poor barrier capacity of the above-mentioned steel-plastic grid, the utility model provides a steel-plastic grid thermal composite geotextile.

[0004] The technical solution of this utility model is as follows:

[0005] A steel-plastic grid thermal composite geotextile, comprising a non-woven fabric, wherein a transverse grid belt and a longitudinal grid belt are provided on one side of the non-woven fabric;

[0006] The length direction of the transverse grid strip is parallel to the length direction of the non-woven fabric, and multiple strips are arranged at intervals along the width direction of the non-woven fabric;

[0007] The longitudinal grid strips are parallel in length to the width of the non-woven fabric, and a plurality of them are spaced apart along the length of the non-woven fabric.

[0008] The two adjacent transverse grid belts are respectively located on the two sides of the same longitudinal grid belt close to and away from the non-woven fabric;

[0009] The adjacent surfaces of the transverse grid strips, the longitudinal grid strips and the non-woven fabric are bonded together.

[0010] By staggering the transverse grid strips and the longitudinal grid strips, the strength of the composite geotextile can be effectively improved.

[0011] As a preferred solution, two adjacent longitudinal grid strips are located on the sides of the same transverse grid strip, close to and away from the non-woven fabric. By adopting a staggered weaving arrangement, the strength of the composite geotextile can be further improved.

[0012] The specific arrangement of the above-mentioned transverse grid strips is that the ratio of the total width of all transverse grid strips to the width of the non-woven fabric is in the range of 1 / 6 to 1 / 4. Avoid too many transverse grid strips, which may cause the composite geotextile to have poor flexibility, and avoid too few transverse grid strips, which may cause low strength.

[0013] The specific width specifications of the transverse grid strips are as follows: the ratio of the width of a single transverse grid strip to the width of the non-woven fabric is in the range of 1 / 60-1 / 30. A smaller grid strip will increase the processing difficulty, while a wider grid strip will increase the width of adjacent grid strips, resulting in lower strength in some parts of the composite geotextile.

[0014] As a preferred solution, the width of the transverse grid strip is smaller than the spacing between adjacent transverse grid strips. To a certain extent, the transverse grid strips are reasonably separated to avoid excessive number of transverse grid strips in a certain area.

[0015] In order to reduce the processing difficulty, the width of the transverse grid strip is the same as that of the longitudinal grid strip. The grid strips of the same specification can be cut to obtain grid strips of two required specifications.

[0016] As a preferred solution, the spacing between adjacent transverse grid bands or longitudinal grid bands is the same.

[0017] The specific structure of the above-mentioned grid belt is that the transverse grid belt and the longitudinal grid belt are both made of high-strength steel wire wrapped by high-density polyethylene.

[0018] In order to improve the bonding strength between the transverse grid belt and the non-woven fabric or the longitudinal grid belt, the width of a single transverse grid belt is not less than 50 mm.

[0019] As a preferred solution, the minimum spacing between the transverse grid belt and the non-woven fabric in the length direction is not equal to 0, and the minimum spacing between the longitudinal grid belt and the non-woven fabric in the width direction is not equal to 0. This avoids the grid belt from being placed close to the edge, making it easier to stack the composite geotextile at the edge.

[0020] The beneficial effect of the present invention is that: the present invention is a steel-plastic grid thermal composite geotextile, which, on the basis of the existing steel-plastic grid strength, can have a barrier ability through the setting of non-woven fabric, and in this process, it is necessary to stagger the transverse grid belts and the longitudinal grid belts so that they can be directly connected to the non-woven fabrics respectively to thereby improve the overall connection strength of the structure, and by reasonably setting parameters such as the width specifications and quantity of the grid belts, it can replace the steel-plastic grid for a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] By reading the detailed description of the preferred embodiment below, the solutions and advantages of the present application will become clear to those skilled in the art. The accompanying drawings are only used to illustrate the preferred embodiment and are not to be considered as limiting the present invention.

[0022] In the attached figure:

[0023] Figure 1This is a schematic diagram of the top view of the structure of the utility model;

[0024] Figure 2 This is a side view of the structure of the utility model;

[0025] The components represented by the reference numerals in the figure are:

[0026] 1. Non-woven fabric; 2. Horizontal grille belt; 3. Vertical grille belt. DETAILED DESCRIPTION

[0027] like Figure 1 、 2 The steel-plastic grid thermal composite geotextile shown includes a non-woven fabric 1, and a transverse grid belt 2 and a longitudinal grid belt 3 are arranged on one side of the non-woven fabric 1. Under normal circumstances, the above-mentioned transverse grid belt 2 and longitudinal grid belt 3 are staggered to form a steel-plastic grid, but after the non-woven fabric 1 is additionally arranged, it can have a barrier ability, and after the transverse and longitudinal grid belts 3 are combined with the non-woven fabric 1, the composite structure can also improve the strength, and when bearing weight, it mainly relies on the steel-plastic grid, so it can have a barrier ability while ensuring the original strength of the steel-plastic grid.

[0028] In order to facilitate production and application, the length direction of the transverse grid belt 2 is parallel to the length direction of the non-woven fabric 1, and multiple strips are arranged at intervals along the width direction of the non-woven fabric 1; accordingly, the length direction of the longitudinal grid belt 3 is parallel to the width direction of the non-woven fabric 1, and multiple strips are arranged at intervals along the length direction of the non-woven fabric 1.

[0029] It should be noted that in the above structure, due to the need to connect with the non-woven fabric 1, the use of conventional steel-plastic grids can easily cause the horizontal or vertical grid belts to float and cannot be directly connected to the non-woven fabric 1. For this reason, the two adjacent horizontal grid belts 2 are respectively located on the two sides of the same longitudinal grid belt 3 close to and away from the non-woven fabric 1, such as Figure 2 As shown, that is to say, the transverse grid belt 2 and the longitudinal grid belt 3 need to be staggered and directly connected to the non-woven fabric 1 respectively. By adopting the above method, the connection tightness of the non-woven fabric 1, the transverse grid belt 2 and the longitudinal grid belt 3 can be improved to avoid the phenomenon of separation, which affects the use. It is not limited to the above setting method. In order to completely make the transverse grid belt 2 and the longitudinal grid belt 3 staggered and tightly connected, as a preferred solution, the two adjacent longitudinal grid belts 3 are respectively located on both sides of the same transverse grid belt 2 close to and away from the non-woven fabric 1. By adopting a staggered weaving arrangement, the strength of the composite geotextile can be further improved. In other words, as Figure 1 As shown, the nonwoven fabric 1 can be connected to the transverse grid bands 2 and the longitudinal grid bands 3 in an alternating manner in both the length and width directions.

[0030] In the above structure, the adjacent surfaces of the transverse grid strip 2, the longitudinal grid strip 3 and the non-woven fabric 1 are bonded together, and the bonding method can be through hot melting or using an adhesive, which can be used according to needs.

[0031] The above structure can be used to effectively improve the strength of the composite geotextile by staggering the transverse grid strips 2 and the longitudinal grid strips 3. While having the structural strength of the steel-plastic grid, it can also have a barrier capability to prevent substances from passing through the holes of the conventional steel-plastic grid. However, it should be noted that in order to connect with the non-woven fabric 1, the connection method of the transverse grid strips 2 and the longitudinal grid strips 3 is different from that of the existing steel-plastic grid. Instead, they need to be staggered up and down, so that both the transverse grid strips 2 and the longitudinal grid strips 3 can be connected to the non-woven fabric 1 to improve the connection strength of each structural member.

[0032] In the above structure, the specific structure of the grid belt is that the transverse grid belt 2 and the longitudinal grid belt 3 are both made of high-strength steel wire wrapped by high-density polyethylene.

[0033] In order to improve the bonding strength between the transverse grid belt 2 and the non-woven fabric 1 or the longitudinal grid belt 3, the width of a single transverse grid belt 2 is not less than 50 mm. When the grid belt with a smaller width is connected to the non-woven fabric 1, its contact area is smaller, so the connection is not stable enough. Moreover, the smaller the width of the grid belt, the greater the required quantity. To a certain extent, the number of arrangements needs to be increased, thereby increasing the difficulty of production.

[0034] As a preferred embodiment, the transverse grid strips 2 are arranged so that the ratio of the total width of all transverse grid strips 2 to the width of the nonwoven fabric 1 is between 1 / 6 and 1 / 4. This avoids excessive number of transverse grid strips 2, which may reduce the flexibility of the composite geotextile, and excessive number of grid strips 2, which may reduce strength. By controlling the width ratio of the grid strips to the nonwoven fabric 1, the overall structural strength and flexibility of the geotextile can be controlled.

[0035] In addition to the total width of the overall grid belt, the width of a single grid belt also needs to be designed. When the overall grid belt width is determined, a larger number of small-width grid belts and a smaller number of large-width grid belts can both meet the above-mentioned overall width requirements. However, in actual use, there are large differences in usage. For this reason, the specific width specifications of the above-mentioned transverse grid belt 2 are that the ratio of the width dimension of a single transverse grid belt 2 to the width dimension of the non-woven fabric 1 is in the range of 1 / 60-1 / 30. Grid belts with smaller widths will increase the difficulty of processing, while grid belts with larger widths will cause the width of adjacent grid belts to increase, thereby causing the strength of some parts of the composite geotextile to be lower. If the volume of the substance to be blocked is small, a grid belt with a smaller width but a larger number can be selected. Otherwise, another type of grid belt needs to be selected to reduce the difficulty of production.

[0036] In the above structure, the width of the transverse grid belt 2 is smaller than the spacing between adjacent transverse grid belts 2. To a certain extent, the transverse grid belts 2 are reasonably distributed to avoid excessive number of transverse grid belts 2 in a certain area.

[0037] Finally, to reduce processing difficulty, the width of the transverse grid strip 2 and the longitudinal grid strip 3 are the same. Two grid strips of the required specifications can be obtained by cutting the same grid strip, eliminating the need to purchase grid strips of different specifications.

[0038] In addition to the above structure, for ease of processing, the spacing between adjacent transverse grid strips 2 or longitudinal grid strips 3 is the same. Furthermore, as a preferred embodiment, the minimum spacing between the transverse grid strips 2 and the non-woven fabric 1 along the length direction is not equal to zero, and the minimum spacing between the longitudinal grid strips 3 and the non-woven fabric 1 along the width direction is not equal to zero. Avoiding the grid strips from being placed close to the edges facilitates stacking the geotextile composites at the edges. If the grid strips are located at the edges, they will rub against each other when two geotextile composites are stacked.
