Abstract
The utility model relates to the plastics processing, in particular to an omnidirectional geotechnical grille which comprises a longitudinal main rib, a horizontal main rib and two oblique auxiliary ribs, wherein one oblique auxiliary rib and the other oblique auxiliary rib are crossly arranged in 90 degrees, the longitudinal main rib and the horizontal main rib are crossly arranged in 90 degrees, two oblique auxiliary ribs are crossed with the longitudinal main rib and the horizontal main rib in 45 degrees, two oblique auxiliary ribs are crossed with the longitudinal main rib and the horizontal main rib to form a big node, the longitudinal main rib and the horizontal main rib are crossed to form a small node, and the big node and the small node are staggered with intervals on the longitudinal direction and the horizontal direction. The strength on the longitudinal direction is enhanced, and is equal to the strength on the horizontal direction, and the force is uniform.
Description
Technical field
The utility model relates to plastic processing, particularly relates to a kind of omnidirectional geo-grid.
Background technology
The plastics geo-grid is mainly used in to be strengthened or reinforcing soil, and has the grid that can lock the grid of openings of soil particle therein.The improvement that omnidirectional's geo-grid is carried out on common plastics geo-grid basis by forming the structure of particular design, makes omnidirectional's geo-grid evenly stressed in 360 ° of directions, strengthens the resistivity of roadbed to external environment condition.High strength stretched plastic geo-grid is extruded into plate by polyolefin such as polypropylene or polyethylene by extruder usually, then sheet material is carried out punching, and preheat stretch forms again.Mainly comprise two kinds of simple tension plastics geo-grid and biaxial tension plastics geo-grid at present, simple tension plastics geo-grid will be used and reduce gradually because the big transverse strength of longitudinal strength is weak at present, and biaxial tension plastics geo-grid is because vertical and horizontal intensity is paid attention to by quite and day by day in market.The biaxial tension geo-grid adopts drift punchings such as the single or double circle that is arranged in a linear, square and rectangle on the market, cause the geo-grid product hole that is square, though improved the transverse strength of geo-grid, diagonal intensity still a little less than.A kind of production method of tri-angle-holed geo-grid is disclosed among the Chinese patent CN03154700.1, each has reasonability to dispersing on the pressure improving loading zone, though product is a triangle, but intensity distributions and product structure characteristic are inconsistent, simultaneously because transverse strength is a weak spot, cause taking place between the track problems such as subgrade settlement, make product not be suitable for Foundation Designs such as speedway, high-speed railway vertical and the demanding place of transverse strength.Product is provided for it because structural factor, cause product to become 60 ° of direction intensity maximums at horizontal direction and with horizontal direction, causing product is the strength weak point at longitudinal direction, do not meet the actual loading situation of product in highway, railway etc. are used, thereby this invention is by adjusting production technology consciously, make product longitudinal direction intensity maximum, but this is inconsistent with product structure again, thereby make that the product practical efficiency is lower, and in use there is destabilizing factor to exist, easily causes taking place between the track problems such as subgrade settlement.
Summary of the invention
The purpose of this utility model provides a kind of omnidirectional geo-grid, overcomes or improve the intensity of prior art longitudinal direction, improves the product practical efficiency, gets rid of destabilizing factor.
The purpose of this utility model is to realize like this, a kind of omnidirectional geo-grid, it comprises vertical main rib, horizontal main rib and two oblique auxilliary ribs, two oblique auxilliary ribs become 90 ° of cross arrangements, vertically main rib becomes 90 ° of cross arrangements with horizontal main rib, vertically vertical main rib of main rib and horizontal main rib and opposite side and horizontal main rib form square, oblique auxilliary rib intersects with laterally main rib is at 45 with vertical main rib, form right-angled triangle, two oblique auxilliary ribs and vertical main rib, laterally main rib intersects big node of formation, vertically main rib and laterally minor node of the crossing formation of main rib, big node and minor node interleaved on the vertical and horizontal both direction is arranged.
The radius R value that described two oblique auxilliary ribs and vertical main rib, horizontal main rib intersect formed angle is 1.5-5mm.
Advantage of the present utility model is, longitudinal strength and transverse strength are suitable, stressed even, increase in diagonal simultaneously and strengthen auxilliary muscle, guarantee that product is at 360 ° of direction mechanics quality stables, when being applied to speedway and high-speed railway, 360 ° of direction mechanical property unanimities can effectively be avoided subgrade settlement generation between the track.And the mould manufacturing of this utility model is simple, die cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, with reference to accompanying drawing 1, a kind of omnidirectional geo-grid, it comprises vertical main rib 5, horizontal main rib 6 and two oblique auxilliary ribs 3,4,4 one-tenth 90 ° of cross arrangements of oblique auxilliary rib 3 and oblique auxilliary rib, vertically main rib 5 and horizontal 6 one-tenth 90 ° of cross arrangements of main rib, vertical main rib 5 and horizontal main rib 6 form square with the vertical main rib 5 and the horizontal main rib 6 of opposite side, oblique auxilliary rib 3,4 with vertically main rib 5 and laterally 6 at 45 intersections of main rib, form right-angled triangle, oblique auxilliary rib 3,4 and vertical main rib 5, laterally main rib 6 intersects big node 1 of formation, vertically main rib 5 and laterally minor node 2 of main rib 6 crossing formation, big node 1 and minor node 2 interleaved on the vertical and horizontal both direction is arranged.Oblique auxilliary rib 3 equates with the width of oblique auxilliary rib 4.Vertically main rib 5 equates with the width of horizontal main rib 6.Oblique auxilliary rib 3,4 width are slightly less than vertical main rib 5 and horizontal main rib 6 width.The radius R value that oblique auxilliary rib 3,4 and vertical main rib 5, horizontal main rib 6 intersect formed angles is 1.5-5mm.
The utility model has strengthened the intensity of longitudinal direction, makes longitudinal strength and transverse strength suitable, and is stressed even, and when being applied to speedway and high-speed railway, 360 ° of direction mechanical property unanimities can effectively be avoided subgrade settlement generation between the track.
