Description
Technical field
The utility model relates to civil engineering material technical field, particularly relates to high density Unidirectional stretched plastic geogrid.
Background technology
Unidirectional stretched plastic geogrid is a kind of is primary raw material with high molecular polymer, adds certain antiultraviolet, anti-aging auxiliary agent, redirects the high strength earth working material of the linearly state that arranges through the simple tension chain molecule at random that makes originally to distribute.Greatly be better than traditional or existing reinforcement material, be that ideal civil engineering is reinforced, reinforcement reinforcement synthetic materials, be divided into simple tension polypropylene geogrid and simple tension high density polyethylene (HDPE) geo-grid according to raw material difference.
Simple tension polypropylene geogrid is with polypropylene (PP) for raw material, forms through plasticizing extrusion board, punching, heating, stretching.Geo-grid after drawn, has quite high tensile strength and modulus of elasticity, and simple tension polypropylene geogrid is applicable to build the engineering such as reinforced soil retaining wall, dykes and dams, bridge floor, abrupt slope on highway, railway, harbour and rivers,lakes and seas bank.
HDPE monodirectional tension film is the common flat film of HDPE or the HDPE film with special performance of blown film after unidirectional high magnification stretches.Its maximum characteristic is that mechanical strength is high, has excellent kink.
Simple tension polyethylene geo-grid is with polyethylene (PE) for raw material, forms through plasticizing extrusion board, punching, heating, stretching.The creep-resistant property of simple tension polyethylene geo-grid is 2-3 times of simple tension polypropylene (PP) geo-grid, so the creep-resistant property of simple tension polyethylene geo-grid is better, this kind of unidirectional geo-grid is generally used for builds " century-old engineering ".These two kinds of geo-grid, referred to as unidirectional geo-grid, belong to Plastics Geogrids.
At present, simple tension geo-grid is in the application of retaining wall, abutment and abrupt slope engineering etc., need the dynamic load, thermal stresses etc. of bearing active earth pressure, structure top, under reinforcement material is in larger tension force effect for a long time, and under the repeated action of dynamic load, the molecular structure of material produces tired, its performance decays, accelerating grid aging, and the intensity of material own is low, less with sandstone friction factor, unstable chemcial property.
Utility model content
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
High density Unidirectional stretched plastic geogrid, comprise square-grid framework and HDPE monodirectional tension film, it is characterized in that: the HDPE monodirectional tension film of described geo-grid is the HDPE film with special performance after unidirectional high magnification stretches, and is coated on geo-grid surface.
Further, the fabric width of described geo-grid is divided into 1m, 1.1m or 2.6m, 3m.
Further, the adjacent spacing of the transverse direction of described geo-grid is greater than 80cm.
The good effect that the utility model has is:
The unidirectional geo-grid of the utility model object can improve the supporting capacity of engineering greatly, increase the service life, reduce floor space, easy construction, reduction of erection time, reduction cycle cost, reduce maintenance cost, have unidirectional tensile strength high, creep resistance is good, stable chemical nature is large with the friction factor of sandstone.
Accompanying drawing explanation
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is high density Unidirectional stretched plastic geogrid structural representation of the present utility model.
Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction utility model.
Fig. 1 is high density Unidirectional stretched plastic geogrid structural representation of the present utility model.
High density Unidirectional stretched plastic geogrid, comprise square-grid framework and HDPE monodirectional tension film, it is characterized in that: geo-grid HDPE monodirectional tension film is the HDPE film with special performance after unidirectional high magnification stretches, and is attached to geo-grid surface.
Wherein, the fabric width of geo-grid is divided into 1m, 1.1m or 2.6m, 3m.
Wherein, the adjacent spacing of the transverse direction of geo-grid is greater than 80cm.
As shown in the figure, high density Unidirectional stretched plastic geogrid, structure is strip grid, horizontal adjacent spaces spacing is greater than 80cm, the fabric width of geo-grid is divided into multiple, make in process at it, Surface Machining has HDPE monodirectional tension film, active earth pressure is being born with the unidirectional geo-grid that high density polyethylene (HDPE) (HDPE) is raw material, the dynamic load on structure top, thermal stresses etc., under reinforcement material is in larger tension force effect for a long time, and under the repeated action of dynamic load, it is high with high density to be that the geo-grid of base material has unidirectional tensile strength, creep resistance is good, stable chemical nature, with the advantage such as the friction factor of sandstone is large.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
