Abstract
A knotting type steel plastic dual direction geotechnical grille is provided which is a high strength one. The current geotechnical grille is incapable for a site regulation in terms of length or width and features a poor strength of panel point after a splicing. The dual direction geotechnical grille is composed of one set of longitudinal strips 1 which is equipped with one set of connecting holes 2 through which a horizontal strip passes to fix at the longitudinal strip 1. The horizontal strip 3 and or the longitudinal strip 1 is a polymer wire packaing structure. A polymer material packages three beams or two beams metal wires, e.g. steel wire or high strength of nylon wire, along a length extension. The dual direction geotechnical grille can reduce and avoid a rive caused by widening a road and by an unbalanced settlement of a roadbed at a section of poor geographical condition and at the same time intensify a surface tensile strength of a large earthwork construction including road, dyke, airport, bridge abutment, dock and bulkhead wall.
Description
Technical field: the utility model relates to a kind of geo-grid of fixing and strengthen unfavorable geology in a kind of civil works.
Background technology: the geo-grid in past is a plastic grill, and intensity is low, and distortion is big, can not on-the-spotly adjust length or width after once being made into, and after splicing, node strength is bad.
Summary of the invention:
The technical problems to be solved in the utility model: provide a kind of woollen yarn knitting formula steel to mould two-way geo-grid, its intensity height is out of shape for a short time, and size is adjusted easily.
The technical scheme that addresses the above problem:
Woollen yarn knitting formula steel is moulded two-way geo-grid, and its composition comprises: one group of taeniae, have one group of connection holes on the described taeniae, and described horizontal stripe passes described connection holes and described taeniae is fixed.
Above-mentioned woollen yarn knitting formula steel is moulded two-way geo-grid, and described horizontal stripe and/or described taeniae are macromolecule bag silk structure, is surrounded by three beams or two bundle wire or high-strength nylon yarns in described macromolecular material along its length.
Above-mentioned woollen yarn knitting formula steel is moulded two-way geo-grid, and the hole of described horizontal stripe or described taeniae connection place is arranged in the gap of wherein any two bundles of described silk.
Above-mentioned woollen yarn knitting formula steel is moulded two-way geo-grid, and described horizontal stripe has projection, and described projection is passed described connection holes fixes described horizontal stripe and described taeniae.
Beneficial effect compared with prior art:
1. the utility model can be with horizontal stripe and taeniae predetermined fixed in factory, also can insert fixing according to the on-the-spot volume of the situation at scene, therefore can adapt to various massifs, the requirement of the length of highway subgrade, railway bed or width and shape, can transport in the mode of belt strip, reduce freight rate and construction cost.Need the splicing of big longitudinal joint or transverse joint hardly, overall performance is good, has overcome the mode that existing procucts must splice on fabric width, and the stretching resistance of avoiding of bringing owing to this splicing reduces, avoided the waste of material of splicing place, will be greatly enhanced application life.
2. wherein be added with the reinforced wire of metal or other high-strength tensile materials, tensile strength is big, can reduce and avoid crack because of old highway is widened and cause owing to settlement of subgrade in the unfavorable geology highway section, can significantly strengthen the stability on bases such as highway engineering, dam construction, airport engineering, obvious effects be arranged for the surface of strengthening big shape soil body building such as abutment, harbour, retaining wall.
3. traditional product is obviously lowered by force intensity in stitching direction, can only bear bigger pulling force at its original length direction.This product can bidirectional stress owing to not splicing.
4. the mode that adopts projection to inlay is constructed easily, can be fit to wider needs.

Embodiment 1.
Woollen yarn knitting formula steel is moulded two-way geo-grid, and its composition comprises: one group of taeniae 1, have one group of connection holes 2 on the described taeniae, and described horizontal stripe 3 passes described connection holes 2 and fixes with described taeniae 1.
Embodiment 2:
Embodiment 1 described woollen yarn knitting formula steel is moulded two-way geo-grid, and described horizontal stripe 3 and/or described taeniae 1 are macromolecule bag silk structure, is surrounded by three beams or two bundle wires 4 along its length such as steel wire or high-strength nylon yarn 4 in described macromolecular material.
Embodiment 3:
Above-mentioned woollen yarn knitting formula steel is moulded two-way geo-grid, and the hole of described horizontal stripe or described taeniae connection place is arranged in the gap of wherein any two bundles of described silk.If two silks can open a hole in the position of each node, if three silks can open pair of holes.
Embodiment 4:
Above-mentioned woollen yarn knitting formula steel is moulded two-way geo-grid, and described horizontal stripe 3 has projection 5, alternately is located at the two sides of horizontal stripe, inserts described connection holes 2 up and down successively in described protruding 5 minutes, passes taeniae, and described horizontal stripe 3 is fixedly connected with described taeniae 1.
