Description

Technical Field

[0001] The utility model belongs to the technical field of geogrids, and in particular relates to a reinforced geogrid. Background Art

[0002] Geogrid is a major geosynthetic material with unique properties and functions. It is often used as reinforcement material for reinforced soil structures or reinforcement material for composite materials, and is widely used in various civil engineering fields.

[0003] Geogrids can be divided into four categories according to their materials: plastic geogrids, steel-plastic geogrids, glass fiber geogrids and polyester warp-knitted polyester geogrids. Among them, plastic geogrids are made by punching holes in extruded polymer sheets (mostly made of polypropylene or high-density polyethylene) and then directional stretching them under heating conditions. During the manufacturing process, the polymer molecules will rearrange and orient themselves during the heating and stretching process, which strengthens the bonding force between the molecular chains and thus increases their strength.

[0004] Geogrids can be used in water conservancy projects for dikes, dams, rivers, canals, sea dike construction, reservoir hazard removal and reinforcement, etc.; in construction projects, they can be used for foundation reinforcement to improve the overall bearing capacity of the foundation; in transportation projects, the use of geogrids can prevent premature settlement and damage of railways and roads on soft soil foundations.

[0005] Existing geogrids are usually mesh structures consisting of transverse grids and longitudinal grids, which have poor reinforcement performance, low tear strength, and are prone to deformation. Utility Model Content

[0006] The purpose of the utility model is to provide a reinforced geogrid in view of the above-mentioned technical problems, so as to achieve the effect of enhancing the strength of the geogrid and increasing the overall stability of the slope.

[0007] In view of this, the utility model provides a reinforced geogrid, comprising:

[0008] A first grid bar, wherein a plurality of the first grid bars are arranged in parallel and at intervals;

[0009] A plurality of second grid bars are arranged in parallel and spaced apart along the length direction of the first grid bars;

[0010] Among them, the first grid bars and the second grid bars are perpendicularly staggered to form a plurality of cells, and a reinforcement part is provided at the intersection of the first grid bars and the second grid bars, and the thickness of the reinforcement part is greater than the thickness of the first grid bars and the second grid bars. The upper and lower surfaces of the reinforcement part are respectively provided with a grip structure and an anti-slip structure, and the grip structure is used to increase the grip force of the bottom of the geogrid, and the anti-slip structure is used to increase the friction between the top of the geogrid and the soil.

[0011] In this technical solution, geogrids are laid on inclined slopes. Due to the effect of gravity, the geogrids may slide down under the effect of gravity, or the soil on the surface of the geogrid may cause landslides due to insufficient connection between the geogrid and the geogrid. The strength of the geogrid can be enhanced by the thickened reinforcement part, and the geogrid can be resistant to tearing and deformation. The grip structure can enhance the connection between the geogrid and the soil underneath it. The anti-slip structure can enhance the connection between the soil on the surface of the geogrid and the geogrid. The geogrid can increase the overall stability of the slope.

[0012] Furthermore, the gripping structure includes connecting nails extending from the bottom surface of the reinforcement part.

[0013] In this technical solution, during construction, the geogrid is laid, the soil is spread, and then compacted. During the compaction process, the connecting nails can be embedded in the soil layer below the geogrid.

[0014] Furthermore, the diameter of the connecting nail gradually decreases from the reinforcement portion.

[0015] In this technical solution, the conical structure of the connecting nail can enable it to be better embedded in the underlying soil layer.

[0016] Furthermore, the anti-slip structure includes an anti-slip protrusion extending from the top surface of the reinforcement part.

[0017] Furthermore, the cells are in a square shape, and each cell is provided with four reinforcing ribs forming a square.

[0018] Furthermore, a locking column extends outward from the side surface of each reinforcing rib.

[0019] In this technical solution, the locking column can be inserted into the soil in the cell to strengthen the connection between the geogrid and the soil.

[0020] Furthermore, a connecting hole is provided on the side surface of each reinforcing rib.

[0021] In this technical solution, the soil inside and outside the square enclosed by the reinforcement bars in the cell is connected through connecting holes, thereby increasing the integrity and connectivity of the soil.

[0022] Furthermore, the reinforcement portion is triangular in shape.

[0023] In the present technical solution, the triangle shape can increase the connection stability between the reinforcement portion and the first grid bar and the second grid bar.

[0024] Furthermore, the reinforcement portion, the first grid bar and the second grid bar are integrally formed.

[0025] The beneficial effects of the utility model are:

[0026] 1. When laying geogrids on inclined slopes, the geogrids may slide down due to gravity, or the soil on the surface of the geogrid may not be connected to the geogrid enough, causing landslides. The thickened reinforcement part can enhance the strength of the geogrid, resist tearing and deformation, and the grip structure can enhance the connection between the geogrid and the soil below it. The anti-slip structure can enhance the connection between the soil on the surface of the geogrid and the geogrid. The geogrid can increase the overall stability of the slope.

[0027] 2. The conical structure of the connecting nail enables it to be better embedded in the underlying soil layer.

[0028] 3. The locking column can be inserted into the soil inside the cell to strengthen the connection between the geogrid and the soil.

[0029] 4. The soil inside and outside the square enclosed by the reinforcement bars in the cell is connected through connecting holes to increase the integrity and connectivity of the soil.

[0030] 4. The triangle shape can increase the connection stability between the reinforcement part and the first and second grid bars. BRIEF DESCRIPTION OF THE DRAWINGS
