Background technology
The simple tension geo-grid be a kind of be primary raw material with the high molecular polymer, add certain antiultraviolet, anti-aging auxiliary agent, make original distribution chain molecule at random redirect arrangement through simple tension and be linear condition, be pressed into thin plate again towards regular hole pattern through extruding, then the high strength geotechnique material that forms of longitudinal stretching.Make macromolecule become the direct line sexual state netted globality structure of oblong that also formation is evenly distributed, node strength is high in this process.This kind structure has quite high hot strength and stretch modulus, tensile strength reaches 100-200Mpa, level near mild steel, be better than high early stage (elongation rate is 2%-5%) hot strength and stretch modulus that traditional or this series products of existing reinforcement material, particularly the said firm has more super world level greatly.The locking system of bearing and spreading of desirable power is provided to soil.This product hot strength big (＞150Mpa), adapt to various soil, be the reinforcement reinforcement material that widely adopts at present.
The cross section of present simple tension geo-grid all is plane or rectangular-shaped, in use following problem occurs through regular meeting: plane stretch-proof performance is more weak, and relatively more fragile, the situation that occurs fractureing through regular meeting; Simultaneously, plane bar rod is in use often in case have and all can occur the inconsistent situation of bar rod overbending direction under the crooked situation; Moreover the pulling force that bears because of plane simple tension grid is less, what therefore its width can not be done is wideer, existingly generally can only reach 2.5-3m, best can not surpass 4m, therefore in work progress, need repeatedly and do not lay, increased labour intensity virtually and reduced the pulling force that bears of integral body.
Summary of the invention
Fracture, be subjected to the little phenomenon of pulling force easily in order to overcome existing simple tension geo-grid, the utility model provides with a kind of simple tension geo-grid, this simple tension geo-grid have bear pulling force greatly, the advantage of frangibility not.
For achieving the above object, the technical program is as follows:
A kind of simple tension geo-grid, comprise the grid body, the horizontal and vertical direction of grid body upper edge grid body is provided with the elliptical aperture of array arrangement, and the major axis of elliptical aperture is parallel with the horizontal and vertical direction of grid body respectively with minor axis, the adjacent both sides of elliptical aperture are respectively vertical bar rod and Cross slat rod, described vertical bar rod crossed with excellent connection of Cross slat, and the cross section of Cross slat rod and vertical bar rod is non-planar.
Further, the major axis of elliptical aperture is parallel with the length direction of grid body on the described grid, and the minor axis of elliptical aperture is parallel with the width of grid body.
Further, the rugosity of the bar rod of described grid upper edge grid length direction is less than along the rugosity of grid width.
Further, described cross section is column, is preferably semiellipse shape or ellipticity.
Further, described Cross slat rod and vertically in the bar rod major axis of the oval cross section of thicker bar rod be 10-20mm, be 4-8mm than the major axis of the oval cross section of slice rod.
Further, the major axis of described elliptical aperture is 17-23cm.
Further, the width of described grid is 5-8m.
A kind of plastic plate for the production of the simple tension geo-grid, the length direction array of described plastic plate upper edge plastic plate is provided with the lengthways of rod perpendicular to the plastic plate width, be provided with the horizontal rib of connection lengthways of rod between the adjacent lengthways of rod, laterally be provided with circular hole between rib and the horizontal rib.
Further, described rib is located at the two sides of plastic plate and is distributed in the face of claiming about sheet material.
Operating principle of the present utility model and the course of work are as follows:
This simple tension geo-grid comprises the grid body, array is provided with elongated hole on the grid body, the two ends of elongated hole are respectively Cross slat rod and vertical bar rod, the cross section of Cross slat rod of the present utility model and vertical bar rod is non-planar, just solved the problem of existing grid fragility, frangibility, simultaneously, because cross section changes into non-planarly, also increased the ultimate tension that grid bears.
This cross section is column: such as ellipse or semiellipse shape, the pulling force that is subjected to of a whole like this rod can strengthen greatly.
With the cross section of bar rod by the plane ellipticity that is optimized to, and by the parameter of elliptical aperture and cross section is set, the width of this unidirectional geo-grid can be issued to 5-8m in the situation of bearing big load, greatly reduces labour intensity, has improved the pulling force that integral construction bears.
