Abstract
The invention discloses a stereoscopic geogrid, comprising a base cloth layer, wherein a reinforcing grid is arranged on the base cloth layer; the reinforcing grid is in a latticed shape; the reinforcing grid is formed by connecting a plurality of transverse rib belts with a plurality of longitudinal rib belts; the cross sections of the transverse rib belts and the longitudinal rib belts are circular; and the transverse rib belts and the longitudinal rib belts are formed by wrapping glass fibres via high-density polyethylene interlayers. Via the mode aforementioned, the stereoscopic geogrid disclosed by the invention is capable of obviously enhancing bearing strength, low in cost, and simple to manufacture.
Description
Technical field
The present invention relates to the geo-grid field, particularly relate to a kind of solid geogrid.
Background technology
Warp knitting geogrid is a kind of reinforcement material, plays the reinforcing humidification in soil body engineering, and being designed to the trellis state structure is in order not exclusively to isolate soil layer, to make native stone directly produce interlock, increasing the globality of the soil body and the intensity that meets with stresses.The common plastics product forms because of congenital limitation and the hot extrusion of its raw molecule structure, and door is narrow, and rolling is short, and creep-resistant property is poor, and intensity also increases and executes lower overlap joint loss far away from fiber grid.At present domestic widely used be the macromolecular material geo-grid, its performance and specification are basic identical, are to adopt the macromolecular compound such as polyethylene to form through extruding under the uniform temperature condition.Macromolecule geo-grid itself is soft and do not have rigidity, can not blow, back-up sand soil at once, inserts the subsequent handling of the Soft Ground such as vertical drainage body, causes the engineering time to prolong.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of solid geogrid, can obviously improve bearing strength, and cost is low, makes simple.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of solid geogrid is provided, comprise: base cloth layer, be provided with the reinforcement grid on the described base cloth layer, described reinforcement grid is latticed, described reinforcement grid comprises that a plurality of cross rib bands and a plurality of longitudinal rib band are formed by connecting, and described cross rib band and longitudinal rib band cross section are rounded, and described cross rib band and longitudinal rib band are formed through high density polyethylene (HDPE) interlayer parcel by glass fiber.
In a preferred embodiment of the present invention, described cross rib band and longitudinal rib band form through ultrasonic bonding.
In a preferred embodiment of the present invention, described base cloth layer is made by in nylon, polyethylene or the polyester fiber one or more.
In a preferred embodiment of the present invention, described reinforcement grid is connected with base cloth layer by adhesive layer.
In a preferred embodiment of the present invention, the width of described cross rib band and longitudinal rib band is 0.02-0.05mm.
The invention has the beneficial effects as follows: solid geogrid of the present invention can obviously improve bearing strength, and cost is low, makes simple.
Description of drawings
Fig. 1 is the structural representation of solid geogrid one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, base cloth layer, 2, strengthen grid, 3, the cross rib band, 4, the longitudinal rib band.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, a kind of solid geogrid, comprise: base cloth layer 1, be provided with on the described base cloth layer 1 and strengthen grid 2, described reinforcement grid 2 is latticed, described reinforcement grid 2 comprises that a plurality of cross rib bands 3 and a plurality of longitudinal rib band 4 are formed by connecting, and described cross rib band 3 and longitudinal rib band 4 cross sections are rounded, and described cross rib band 3 and longitudinal rib band 4 are formed through high density polyethylene (HDPE) interlayer parcel by glass fiber.
In addition, described cross rib band 3 and longitudinal rib band 4 form through ultrasonic bonding, and ultrasonic bonding is to strengthen grid 2 overall structures firm.
In addition, described base cloth layer 1 is made by in nylon, polyethylene or the polyester fiber one or more.
In addition, described reinforcement grid 2 is connected with base cloth layer 1 by adhesive layer.
In addition, the width of described cross rib band 3 and longitudinal rib band 4 is 0.02-0.05mm.
Be different from prior art, solid geogrid of the present invention can obviously improve bearing strength, and cost is low, makes simple
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes manual of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
