Description

Technical Field

[0001] This utility model relates to the field of geogrids, and more particularly to the field of geogrid technology for soft terrain, specifically referring to a geogrid suitable for soft terrain. Background Technology

[0002] Geogrids are a major type of geosynthetic material, possessing unique properties and functions compared to other geosynthetics. They are commonly used as reinforcement in reinforced soil structures or composite materials.

[0003] Geogrids are classified into four main categories: plastic geogrids, steel-plastic geogrids, fiberglass geogrids, and polyester warp-knitted geogrids. A geogrid is a two-dimensional mesh or a three-dimensional mesh screen with a certain height, made of polymers such as polypropylene and polyvinyl chloride through thermoplasticizing or molding. When used in civil engineering, it is called a geogrid.

[0004] Currently, common geogrids are composed of several quadrilateral units or several regular hexagonal units arranged in rows and columns. Reinforcing ribs are then set inside the regular hexagonal or quadrilateral units to enhance the strength of the geogrid. For example, a double hexagonal reinforced geogrid with application number CN202122376284.2 is described. However, the internal hexagonal and regular hexagonal units are connected by reinforcing ribs. The strength is high at the endpoints of the regular hexagonal units, but there is no reinforcement for the side length of the hexagons. Therefore, the side length strength of the hexagons is small. Furthermore, due to the setting of several reinforcing ribs, the geogrid has poor deformation capacity, which is not conducive to its use in soft terrain. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a geogrid suitable for soft terrain. Quadrilateral units are placed within regular hexagonal units, with the corners of the quadrilaterals located on the four sides of the hexagons, thereby enhancing the strength of the sides of the regular hexagonal units. At the same time, the stiffeners are eliminated, thereby enhancing the deformation capacity of the regular hexagonal units, making them suitable for soft terrain.

[0006] This utility model is achieved through the following technical solution: a geogrid suitable for soft terrain, comprising a plurality of regular hexagonal units arranged in rows and columns, and quadrilateral units located within the regular hexagonal units, wherein the four corners of the quadrilateral units are respectively located on the four sides of the regular hexagonal units.

[0007] When this utility model is used, the geogrid deforms first and then bears force. The quadrilateral unit is placed inside the regular hexagonal unit, and the corner of the quadrilateral is located on the four sides of the hexagon, thereby enhancing the strength of the sides of the regular hexagonal unit. At the same time, the reinforcing ribs are eliminated, thereby enhancing the deformation capacity of the regular hexagonal unit, so that it can be used in soft terrain.

[0008] Preferably, the quadrilateral unit is rectangular. The rectangular design in this preferred embodiment provides greater stability under stress compared to a quadrilateral, and is less prone to deformation, thus avoiding excessive deformation of the quadrilateral and reducing the internal support strength of the regular hexagonal unit.

[0009] Preferably, the corner of the quadrilateral unit is located at the midpoint of the corresponding side length, and the quadrilateral unit divides the regular hexagonal unit into two isosceles trapezoidal units and two isosceles triangular units that are symmetrically arranged about the quadrilateral unit.

[0010] This preferred solution strengthens the regular hexagonal unit by placing the corner of the quadrilateral unit at the midpoint of the corresponding side length, thereby enhancing the stability of the regular hexagonal unit through the arrangement of the quadrilateral unit corners at the midpoint of the corresponding side length. At the same time, the formation of two isosceles trapezoidal units and two isosceles triangular units further enhances the stability of the regular hexagonal unit.

[0011] Preferably, the hexagonal units arranged in rows intersect at their endpoints, and the adjacent hexagonal units arranged in columns have two sides that extend laterally and are collinear. The quadrilateral units have two sides that extend laterally and two sides that extend longitudinally.

[0012] This preferred solution directly strengthens the lateral strength through the two side lengths of the quadrilateral unit, and directly strengthens the longitudinal strength through the two side lengths.

[0013] Preferably, the lateral extension of the quadrilateral element is longer than the longitudinal extension. This preferred design increases the area of ​​the isosceles trapezoid and decreases the area of ​​the isosceles triangle, making it suitable for soft terrain with relatively large deformation.

[0014] Preferably, the quadrilateral unit is a square. This preferred design increases the area of ​​the isosceles triangle and decreases the area of ​​the isosceles trapezoid, resulting in strong triangle stability, which is suitable for soft terrain with relatively small deformations.

[0015] The beneficial effects of this utility model are as follows: placing a quadrilateral unit inside a regular hexagonal unit, with the corners of the quadrilateral located on the four sides of the hexagon, enhances the strength of the sides of the regular hexagonal unit. Simultaneously, eliminating the reinforcing ribs enhances the deformation capacity of the regular hexagonal unit, making it suitable for soft terrain. By positioning the corners of the quadrilateral unit at the midpoints of their corresponding sides, the regular hexagonal unit is strengthened from the midpoints of its sides. Furthermore, the formation of two isosceles trapezoidal units and two isosceles triangular units enhances the stability of the regular hexagonal unit. The two sides of the quadrilateral unit directly strengthen the lateral strength, and the two sides directly strengthen the longitudinal strength. Attached Figure Description

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0020] Example 1:

[0021] See attached document Figure 1 This utility model discloses a geogrid suitable for soft terrain, comprising a plurality of regular hexagonal units arranged in rows and columns, and quadrilateral units located within the regular hexagonal units. The regular hexagonal units arranged in rows intersect at their endpoints, and the adjacent and laterally extending sides of the regular hexagonal units arranged in columns are collinear.

[0022] The quadrilateral unit is rectangular, and the four corners of the quadrilateral unit are located on the four sides of the regular hexagonal unit. Two sides of the quadrilateral unit extend horizontally, and two sides extend vertically.

[0023] The corner of the quadrilateral unit is located at the midpoint of the corresponding side length. At this time, the side length of the quadrilateral unit extending laterally is longer than the side length extending vertically. The quadrilateral unit divides the regular hexagonal unit into two isosceles trapezoidal units and two isosceles triangular units that are symmetrically arranged about the quadrilateral unit.

[0024] Example 2:

[0025] This embodiment provides a geogrid suitable for soft terrain, comprising a plurality of regular hexagonal units arranged in rows and columns, and quadrilateral units located within the regular hexagonal units. The regular hexagonal units arranged in rows intersect at their endpoints, and the adjacent and laterally extending regular hexagonal units arranged in columns are configured with collinear side lengths.

[0026] The quadrilateral unit is a square, and the four corners of the quadrilateral unit are located on the four sides of the regular hexagonal unit. Two sides of the quadrilateral unit extend horizontally, and two sides extend vertically.

[0027] Specifically, they are arranged in horizontal rows and vertical columns.

[0028] In use, the geogrid deforms before being stressed. Rectangular or square quadrilateral units are placed within regular hexagonal units, with the corners of the quadrilaterals located on the four sides of the hexagons. This enhances the strength of the hexagonal units' sides. Simultaneously, the elimination of reinforcing ribs further enhances the deformation capacity of the hexagonal units, making them suitable for soft terrain. By positioning the corners of the quadrilateral units at the midpoints of their corresponding sides, the hexagonal units are strengthened from these midpoints. The formation of two isosceles trapezoidal units and two isosceles triangular units further enhances the stability of the hexagonal units. The two sides of the quadrilateral units directly strengthen the lateral direction, and the two sides also directly strengthen the longitudinal direction.
