Description

High-strength geogrid

Technical Field

The invention relates to the technical field of geogrids, in particular to a high-strength geogrid.

Background

In engineering construction such as roadbed, dykes and dams, bank protection, adopt the mode that sets up the reinforcement material on the soil body often, transmit the friction effect that roadbed and soil body produced to the reinforcement material on, play the effect of protection roadbed, can also be used for preventing the soil erosion and water loss of bank protection.

The reinforcing materials commonly used at present are generally integrally-shaped or net-shaped geogrids, and the strength of the geogrids is improved by adding reinforcing materials such as steel wires into the reinforcing belts. However, in the use process, the existing geogrid is easy to break, so that the roadbed is easy to deform or break.

Disclosure of Invention

The invention aims to provide a high Jiang Tugong grid so as to solve the problem that in the prior art, the geogrid is easy to break, so that the roadbed is deformed or broken.

The basic scheme provided by the invention is as follows: high-strength geogrid, including a plurality of muscle groups, wherein: the rib groups comprise a plurality of rib bands which are parallel to each other, and the rib bands are mutually crossed to form a triangular grid; the rib band groups are made of high-strength vinylon materials, and the crossed connection points of the rib band groups are bonded and fixed.

The basic scheme has the working principle and beneficial effects that: in the use process of the existing grating, the applicant finds that as the joint of the rib belts on the grating is fixed in a welding mode, the joint is easy to break due to the off-welding, and finally the roadbed at the joint is deformed or broken. In the scheme, a welding connection mode is abandoned, and a high-strength vinylon and bonding mode is adopted, so that on one hand, vinylon is high in strength and good in bonding performance, connection of connection points is not easy to fall off, the situation of fracture is reduced, and the occurrence probability of roadbed deformation or fracture can be reduced; on the other hand, when the road bed receives great effort, the road bed transmits partial stress to the grid, and because high strength vinylon has lower elongation, consequently very easily appear cracked condition when receiving great tensile force in different directions, and in this scheme, still set up the grid that intercrossing formed triangle-shaped between a plurality of muscle group, compare unidirectional or two-way grid among the prior art, the high strength geogrid in this scheme can resist the power of three direction, has better mechanical properties, the creep property is little, thereby the condition that the grid appears splitting has further been reduced, thereby the life of road bed has been prolonged.

Compared with the geogrid in the prior art, the high-strength geogrid in the scheme has high strength, and is not easy to fall off, so that the condition of grid breakage is reduced, and the service life of a roadbed is prolonged.

The first preferred scheme is as follows: as a preferred basic scheme, in the plurality of rib band groups, the widths of the rib bands in each rib band group are the same, and the widths of the rib bands of one rib band group are respectively larger than those of the other rib band groups. The beneficial effects are that: the arrangement of this scheme has both strengthened the stability of structure, and is economical and reasonable again.

And a second preferred scheme is as follows: preferably, as a basic or preferred version one, the band set comprises three sets. The beneficial effects are that: the three rib groups are used as the rib groups with the minimum required number of groups which can be used for weaving the triangular grille, so that the production cost of the grille is reduced.

And a preferred scheme III: preferably, the connection points are all fixed by bonding. The beneficial effects are that: the bonding strength is improved, and scattering is avoided.

The preferable scheme is as follows: preferably, the plurality of tendon groups intersect at the same junction. The beneficial effects are that: compared with the mode that every two of the plurality of rib band groups are intersected at the same point, the mode that the plurality of rib band groups are intersected at the same connecting point can further improve the strength of the connecting point, and therefore the situation that the connecting point is broken is reduced.

The preferable scheme is as follows: preferably, the plurality of tendon groups intersect at the same junction. The beneficial effects are that: in this scheme, set up a plurality of muscle area when crossing on same tie point, can guarantee that the triangle-shaped grid that a plurality of muscle area group alternately formed is all the same.

Detailed Description

The following is a further detailed description of the embodiments:

reference numerals in the drawings of the specification include: a first rib band group 1, a second rib band group 2, a third rib band group 3, a grid and a connecting point 5.

An example is substantially as shown in figure 1: the high-strength geogrid comprises a plurality of rib band groups, wherein each rib band group comprises a plurality of rib bands which are parallel to each other and are in linear orientation, and the rib bands of each rib band group are equal in interval.

The multiple rib band groups are mutually crossed to form a triangular grid, and in particular, the embodiment comprises three rib band groups, namely a first rib band group 1, a second rib band group 2 and a third rib band group 3, wherein the three rib band groups are all filament bundles of high-strength vinylon, and the width of the third rib band group 3 is larger than the width of the first rib band group 1 and the width of the second rib band group 2; the inter-rib-band spacing of the first rib band group 1 is equal to the inter-rib-band spacing of the second rib band group 2, the first rib band group 1 and the second rib band group 2 are intersected with each other, and the third rib band group 3 is intersected with a connecting point 5 of the first rib band group 1 and the second rib band group 2; when the spacing between the rib bands of the third rib band group 3 is equal to the spacing between the rib bands of the first rib band group 1, the three rib band groups are crossed to form an equilateral triangle grid, and when the spacing between the rib bands of the third rib band group 3 is smaller than or larger than the spacing between the rib bands of the first rib band group 1, the three rib band groups are crossed to form an isosceles triangle grid. In other embodiments, more than three sets of tendons may be used.

The rib bands of each rib band group are made of high-strength vinylon materials, and the first rib band group 1, the second rib band group 2 and the third rib band group 3 are fixed at the connecting point 5 in a double-sided bonding mode.

The specific implementation process is as follows: the high-strength geogrid in the embodiment is suitable for occasions such as old road reinforcement, pavement reinforcement, wall surface repair, slope management, shockproof building, dam slope protection and the like, and is particularly suitable for repairing roads with complex road conditions. Taking old road reinforcement as an example, when the high-strength geogrid is used, the high-strength geogrid in the embodiment is spread on a road surface to be repaired, then concrete is covered, and the concrete is solidified. For road surfaces with complex road conditions, such as the condition that the road surfaces are obviously uneven, when repairing, firstly, a layer of concrete needs to be covered on the road surfaces to be repaired in advance, then when the concrete is not solidified yet, a high-strength geogrid is spread on the surface of the concrete, then, a layer of concrete is covered, and when the concrete is solidified, the repair work of the complex road surfaces is completed.
