Description

Rhombic geogrid

Technical Field

The utility model belongs to the technical field of geogrid, a geogrid of rhombus is related to.

Background

Geogrid is widely used in engineering construction such as road bed, dykes and dams, bank protection, can play the effect of protection road bed, bank protection and prevention soil erosion and water loss. The meshes of the existing geogrid are generally square, the stress point of each transverse rib and the stress point of each longitudinal rib of the geogrid are on the same straight line, and if one node is broken in the use process, the line where the node is located can be integrally torn, so that the tensile strength of the geogrid is not high, and the use requirement of a user can not be well met.

Disclosure of Invention

The utility model discloses an overcome prior art's defect, designed the geogrid of a rhombus, tensile strength is high, and the appearance is pleasing to the eye moreover, can satisfy user's user demand well.

The utility model adopts the following specific technical proposal: the utility model provides a rhombus geogrid, includes a set of parallel arrangement's horizontal muscle and a set of parallel arrangement's vertical muscle, and horizontal muscle and vertical muscle cross arrangement form into latticed structure, and the key lies in: the meshes of the latticed structure are rhombic meshes formed by stretching transverse ribs and longitudinal ribs, and nodes are formed at the crossed positions of the transverse ribs and the longitudinal ribs.

The side length of the rhombus is 2-4 cm.

The acute angle of the diamond is α, and the angle is more than 60 degrees and less than α and less than 90 degrees.

The α is 75 °.

The thickness of the node is 0.1-0.5 cm.

The thickness of the transverse ribs and the longitudinal ribs is 0.03-0.2cm

The width of the transverse ribs and the width of the longitudinal ribs are 0.2-1 cm.

The utility model has the advantages that: the net hole shape is stretched into a diamond shape, so that stress points of each node in the direction vertical to the transverse ribs or the longitudinal ribs are all positioned on different straight lines, and when one node is broken in the using process, the influence on other nodes is small, so that the geogrid is high in tensile strength, attractive in appearance and capable of well meeting the using requirements of users.

Detailed Description

The present invention will be described in detail with reference to the following drawings and specific embodiments:

in a specific embodiment, as shown in fig. 1 and 2, a rhombic geogrid includes a set of parallel transverse ribs 1 and a set of parallel longitudinal ribs 2, the transverse ribs 1 and the longitudinal ribs 2 are arranged in a crossed manner to form a grid-shaped structure, the meshes of the grid-shaped structure are rhombic meshes formed by stretching the transverse ribs 1 and the longitudinal ribs 2, and the crossed positions of the transverse ribs 1 and the longitudinal ribs 2 form nodes 3. Stress points of each node 3 in the direction perpendicular to the transverse ribs 1 or the longitudinal ribs 2 are located on different straight lines, and when one node 3 is broken in the using process, the influence on other nodes 3 is small, so that the tensile strength of the geogrid can be improved.

The longer the side length of the rhombus is, the larger the mesh is, the tensile strength of the whole body is also reduced, so in order to better ensure the tensile strength of the geogrid, the utility model discloses set the side length of the rhombus to 2-4cm, the acute angle of the rhombus is α, as shown in figure 1, 60 ° < α < 90 ° and preferably α ═ 75 °.

In order to make the node 3 have a sufficiently high tensile strength, the present invention sets the thickness of the node 3 to 0.1-0.5 cm.

The geogrid is too thick then the materials are more, can raise the cost, and the geogrid is too thin then tensile strength is lower, easy fracture, so the utility model discloses well horizontal muscle 1 and vertical muscle 2's thickness is 0.03-0.2cm, under the prerequisite that satisfies the tensile strength demand, reduces the materials volume as far as possible, practices thrift the cost.

The stretching ribs are too wide, so that more materials are used, the cost is increased, the stretching ribs are too narrow, so that the stretching ribs have lower tensile strength and are easy to break, the width of the transverse ribs 1 and the width of the longitudinal ribs 2 are 0.2-1cm, the material consumption is reduced as far as possible on the premise of meeting the tensile strength requirement, and the cost is saved.

A set of examples and two comparative examples are given below, the only difference between comparative example 1 and example 1, between comparative example 2 and example 2, and between comparative example 3 and example 3 being that the mesh is square, the specific data being shown in table 1 below:

TABLE 1 parameter settings and corresponding Performance parameters for examples 1-5

Can know by the data in table 1, the utility model discloses change geogrid's mesh shape into the rhombus by square, can improve geogrid's tensile strength, the appearance is pleasing to the eye moreover, can satisfy user's user demand well.

The utility model discloses when concrete preparation, at first punch a hole on the polymer panel of extrusion, then carry out directional drawing under the heating condition can. During punching, in the advancing process of the polymer plate, a plurality of groups of holes are punched on the polymer plate by using a die, and the included angle between the connecting line of the central points of all the holes in the same group and the advancing direction of the polymer plate is an acute angle or an obtuse angle, as shown in fig. 3, the geogrid shown in fig. 1 can be formed by oriented stretching; all the holes in the same group are connected by the central point to form a V-shaped structure with the opening facing to the front or the back, as shown in figure 4, and then the geogrid as shown in figure 2 can be formed by directional stretching. Geogrids with different shapes can be selected by users, and the using requirements of the users can be better met.
