Geo-grid landfill in the process of using plays the effect of reinforcing rib in road matrix, although that existing geo-grid all has is corrosion-resistant, the performance of water-fast bubble, but when rainwater accumulates in geo-grid, though can not corrode geo-grid, but the rainwater of accumulation can cause the geo-grid matrix that comes off, thereby affect the reinforcing rib effect of geo-grid, the life-span that causes road matrix.
Utility model content
The existing geo-grid drainage performance of the utility model is poor and cause the problem that geo-grid and road matrix depart from, and provide a kind of geo-grid, can discharge timely the rainwater of accumulation, prevent that geo-grid and road matrix from departing from, thus the application life of improving road matrix.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
Geo-grid, comprise horizontal and vertical grille strip, described horizontal grille strip forms geo-grid with longitudinal grille strip weaving, it is characterized in that: the bottom of described horizontal grille strip is provided with along the groove that laterally grille strip length direction arranges, and the size of the opening of described groove is less than the size of groove bottom.
Further, in described horizontal grille strip, be provided with stainless steel steel wire.
Further, described stainless steel steel wire is distributed on groove periphery.
Further, described groove is arc groove.
Further, the degree of depth of described groove is 1/5-1/2 of horizontal grille strip thickness.
Compared with prior art, the utlity model has following beneficial effect:
One, geo-grid of the present utility model, comprise horizontal and vertical grille strip, laterally grille strip forms geo-grid with longitudinal grille strip weaving, the bottom of described horizontal grille strip is provided with along the groove that laterally grille strip length direction arranges, and the size of the opening of described groove is less than the size of groove bottom.When accumulation rain, by the drainage of groove, can in time rainwater be discharged, thereby prevent that geo-grid and road matrix from departing from, and improves the application life of road matrix.Meanwhile, the opening size of groove of the present utility model is less than the size of groove bottom, in the process of installing, can prevent that the earth of road matrix or foreign material from stopping up groove, guarantees the patency of groove, improves Practical Performance of the present utility model.
Two, in horizontal grille strip of the present utility model, be provided with stainless steel steel wire, can play the effect of strengthening geo-grid intensity, eliminate and because offering groove, bring the impact of strength decreased, ensure the normal use of geo-grid.

Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model upward view;
Fig. 2 is the schematic cross-section of horizontal grille strip one embodiment of the present utility model;
Mark in figure: 1, longitudinal grille strip, 2, horizontal grille strip, 3, groove, 4, stainless steel steel wire.
The specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings and the specific embodiments, and described embodiment is only the utility model part embodiment, is not whole embodiment.Embodiment based in the utility model, those of ordinary skill in the art, not making other embodiment used that obtain under creative work prerequisite, belongs to protection domain of the present utility model.
Geo-grid of the present utility model, comprise horizontal and vertical grille strip, laterally grille strip forms geo-grid with longitudinal grille strip weaving, the bottom of described horizontal grille strip is provided with along the groove that laterally grille strip length direction arranges, and the size of the opening of described groove is less than the size of groove bottom.When accumulation is during rain, by the drainage of groove, can in time rainwater be discharged, thereby prevent geo-grid from soaking for a long time and depart from road matrix, improve the application life of road matrix.Meanwhile, the opening size of groove of the present utility model is less than the size of groove bottom, in the process of installing, can prevent that the earth of road matrix or foreign material from stopping up groove, guarantees the patency of groove, improves Practical Performance of the present utility model.Because when the opening size of groove and groove bottom measure-alike, the earth of road matrix or foreign material are easy to enter inside grooves and stop up groove, thereby destroy the drainage of groove.
In horizontal grille strip of the present utility model, be provided with stainless steel steel wire, can play the effect of strengthening geo-grid intensity, eliminate and because offering groove, bring the impact of strength decreased, ensure the normal use of geo-grid.Geo-grid integral body of the present utility model is formed through thermoplastic or mold pressing by high molecular polymers such as polypropylene, polyvinyl chloride, in the process of thermoplastic or compression molding, adds stainless steel steel wire, sets the shape of groove simultaneously.
Stainless steel steel wire of the present utility model is distributed on groove periphery, can in the consumption that as far as possible reduces stainless steel steel wire, guarantee the intensity of geo-grid to reduce cost of manufacture of the present utility model.
Groove of the present utility model be arc groove, the concentrated phenomenon that can eliminate stress, improves application life of the present utility model.The shape of groove can be also other shapes, and such as being trapezoidal shape, as a kind of preferred mode, groove of the present utility model is arc groove.
The degree of depth of groove of the present utility model is 1/5-1/2 of horizontal grille strip thickness, makes the groove of offering can not affect the intensity of whole geo-grid, improves practicality of the present utility model.The degree of depth of groove can be set according to the situation of road matrix, and when Road Base body is softer, in order to guarantee the drainage of groove, the degree of depth of groove is darker, is set as 1/2 of horizontal grille strip thickness; When Road Base body is harder, the earth of road matrix or foreign material are difficult for entering inside grooves, in order to improve the intensity of geo-grid, the degree of depth setting of groove is more shallow, for 1/5 of horizontal grille strip thickness, thereby make the utility model can be adapted to different road matrixes, improve Practical Performance of the present utility model.
