Abstract
The utility model relates to a three-way drawing geogrid, which is characterized in that grid holes (2) arranged in a grid (1) are in triangular shape, and the grid (1) is integrated by an extrusion mode. A rounded weight relief hole (3) is arranged in the joint between the grid holes (2). The grid (1) is made of polypropylene material. The three-way drawing geogrid has the advantages of ingeniousdesign and simple sue, and the draw direction of the attraction force of the grid is changed through changing the shape of the gird holes; the three-way drawing geogrid can meet the requirements of different environments in the actual application of engineering, improves the carrying capacity of a roadbed and prolongs the service life of the roadbed.
Description
Technical field
The utility model belongs to the geo-grid application, specifically a kind of native a kind of three-dimensional stretching geo-grid that is applied to reinforcing under the grounds such as railway, highway.
Background technology
The geo-grid that is currently applied to ground stabilization materials such as railway, highway has a variety of, the plastic grill that some muscle bandwidth is little can directly produce whole trellis or netted grid by equipment, the connection of muscle interband need not to consider the intensity of tie point owing to be one.But this production can't be produced the whole grid of wideer muscle band owing to be subjected to the restriction of plant equipment, and particularly along with the raising to the grid requirement of strength, a lot of enterprises have developed the high-strength earth work grille of multiple pattern.For example steel is moulded compound geogrid etc.These grids are by the muscle band and the muscle band is crisscross forms, muscle band and muscle band generally are by directly being welded, owing to add reinforcement materials such as steel wire in these compound grid muscle bands, the polythene material of muscle belt surface is very thin, the weld strength of muscle band and muscle band is not high, the easy sealing-off of tie point often influences grid application life owing to the shearing resistance of connecting portion is low in engineering is used.
Two-way geo-grid is distributed to load on the wideer subbase to the lateral confinement interaction energy of roadbase effectively, the thickness of basic unit can reduce, and can prolong application life, simultaneously, two-way geo-grid can also improve the ability that reciprocal load bears in basic unit, reduces the sand suction effect that reciprocal load is given birth to basic unit and bottom.Yet in actual use, two-way geo-grid can only biaxial tension, still can not effectively satisfy the needs under the complex stress environment.
Summary of the invention
The purpose of this utility model is a kind of three-dimensional stretching geo-grid of invention, to overcome above-mentioned drawback.
The technical solution of the utility model is:
A kind of three-dimensional stretching geo-grid, the grate opening in the grid be shaped as triangle, grid stretches one-body molded by extrusion molding.
The junction of described grate opening is provided with circular lightening hole.
The material of described grid is a polypropylene.
The beneficial effects of the utility model are:
Ingenious, the simple use of the utility model design, the gravitation draw direction that passes through to change the shape of grate opening and then change grid in practical engineering application, can adapt to the needs of varying environment, and can prolong the application life of roadbed.The utility model has thoroughly overcome the drawback that unidirectional or biaxial tension geo-grid can only resist the power of one or two direction, and the utility model can resist the power of three directions, has excellent mechanical property, and creep properties is little.
Description of drawings
Fig. 1 is the structural representation of existing two-way geo-grid.
Fig. 2 is a structural representation of the present utility model.
Among the figure: 1 is that grid, 2 is that grate opening, 3 is lightening hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As Fig. 1, a kind of three-dimensional stretching geo-grid, the grate opening 2 in the grid 1 be shaped as triangle, grid 1 stretches one-body molded by extrusion molding.
The junction of grate opening 2 is provided with circular lightening hole 3.
The material of grid 1 is a polypropylene.
Three-dimensional stretching geo-grid of the present utility model not only can three stressed stretchings of direction, and the connecting portion shearing resistance improves greatly, have improved the roadbed supporting capacity, thereby have improved the application life of roadbed.
Claims (3)
1, a kind of three-dimensional stretching geo-grid, it is characterized in that in the grid (1) grate opening (2) be shaped as triangle, grid (1) stretches one-body molded by extrusion molding.
2, three-dimensional stretching geo-grid according to claim 1 is characterized in that the junction of described grate opening (2) is provided with circular lightening hole (3).
3, three-dimensional stretching geo-grid according to claim 1 and 2, the material that it is characterized in that described grid (1) is a polypropylene.
