Technical Field

The utility model relates to a civil engineering technical field, concretely relates to double-deck geogrid of reinforcement type.

Background

Geogrid is a good geosynthetic material used for reinforcing road surfaces, old roads and reinforcing road beds and soft soil foundations. The asphalt pavement reflective crack treatment material is an irreplaceable material in the application of treating the asphalt pavement reflective cracks. The product is a semi-rigid product which is prepared by preparing a reticular base material by an international advanced warp knitting process with high strength and no alkali and carrying out surface coating treatment. It is often used as a reinforcement for reinforced earth structures or as a reinforcement for composite materials. Geogrids are divided into four categories, namely plastic geogrids, steel-plastic geogrids, glass fiber geogrids and polyester warp-knitted polyester geogrids. The grid is a two-dimensional grid or three-dimensional grid screen with a certain height formed by thermoplastic or die pressing of high polymer such as polypropylene, polyvinyl chloride and the like, and is called as geogrid when used in civil engineering. The existing single-layer geogrid is poor in strength and durability.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.

Referring to fig. 1 to 5, the following technical solutions are adopted in the present embodiment: the geogrid comprises an upper geogrid layer 1, a lower geogrid layer 2 and a connecting piece 3; the upper geogrid layer 1 is connected with the lower geogrid layer 2 through a connecting piece 3; the upper geogrid layer 1 and the lower geogrid layer 2 are respectively coated with an upper convex layer 4 and a lower convex layer 5, the bottom of the upper convex layer 4 is integrally connected with a sphere 8, the upper end of the lower convex layer 5 is integrally connected with a ball sleeve 6 matched with the sphere 8, and the ball sleeve 6 is provided with an opening 7; go up the knot layer 4 and be connected through spheroid 8 and the embedding of ball cover 6 between the knot 5 down, melt respectively on last geogrid layer 1 and lower geogrid layer 2 and annotate protruding knot layer structure, strengthen the intensity effect on every layer of geogrid layer, have interlocking interlock ability and constraint nature to the construction basic unit, strengthen construction ground bearing capacity, reduce the settlement of construction ground, and go up geogrid layer 1 and lower geogrid layer 2 both through pressing into ball cover 6 formation connection with spheroid 8 by hand or equipment, the assembly is simple, bilayer structure's thickness adds the thickness of intermediate junction spare again, whole thickness greatly increased, intensity greatly increased.

Go up geogrid layer 1 and lower geogrid layer 2 constitute by a plurality of horizontal grid 9 and a plurality of vertical grid 10, a plurality of horizontal grid 9 and a plurality of vertical grid 10 crisscross network structure that forms, the cross connection point is the node, is connected with strengthening rib 11 between the node of diagonal angle, reinforcing tensile force, the construction is firm not fragile.
