Abstract
The utility model discloses a high-strength flexible slope-protection steel-wire rope, which is formed by braiding the steel wire or the steel ropes, and is composed of a plurality of diamond grid cells; any edge of the diamond grid cell is an arc edge; the arc degree of the arc edge is 0.610 to 0.69; the angle between two edges of the diamond grid cells is 55 to 60 degrees; the diameter of an inner connection circle between the diamond grid cells is 65 mm. Adopting the high-strength flexible slope-protection steel-wire rope, each grid cell of the metal screen is guaranteed to keep a given buffering distance with the ground surface; when the screen suffers a serious impact force, the entire metal screen can be effectively prevented from being damaged.
Description
Technical field
The utility model relates to a kind of wire lath that forms with wire or metallic cable braiding, especially a kind of high-strength flexible bank protection gauze wire cloth.
Background technology
Side slope protection initiatively guard system main composition is divided into wire rope net, ordinary steel wire grid and TECCO high-tensile steel wires grid three classes, the above two are by rope bolt and/or supporting rope fixed form, the third party is by reinforcing bar and/or rope bolt, special-purpose anchor plate and fixed forms such as edge supporting rope in case of necessity, to cover as the flexible net of system's main composition on potential geological disaster domatic, thereby realize its protection purpose.The related high strength bank protection flexible steel wire host of the utility model will be used for side slope protection and go deep into the engineering that soil is implemented greening again, existing gauze wire cloth is bent into a plurality of " it " font with a steel wire earlier usually, another root steel wire is bent into " it " font too and guarantees these two steel wire solderless wrapped connections together, form a plurality of networks unit, the 3rd, four, a N wire rope also adopt common mode, form a big gauze wire cloth at last, the end of adjacent two steel wires bends not slippage.Such gauze wire cloth in actual use, because the network unit of gauze wire cloth all adopts the machine bending, the limit of network unit is straight flange, be laid on the bank protection face of land after because the ground surface unevenness, be that depression or the gauze wire cloth that protrudes all closely contact with the face of land, gauze wire cloth has not a particle of the leeway of buffering after being subjected to external impacts, cause the impact resistance of gauze wire cloth poor, intensity is not high, and significantly reduce the application life of gauze wire cloth.
The utility model content
For solving the problems of the technologies described above, the utility model proposes that a kind of and the bank protection face of land are flexible to be contacted, anti-impact force is strong, the high-strength flexible bank protection gauze wire cloth of long service life, adopt the utility model, each grid cell that has guaranteed wire lath all has certain buffer distance with ground surface, when standing greater impact power, can guarantee effectively that whole wire lath is not damaged.
The utility model is achieved by the following technical solution:
A kind of high-strength flexible bank protection gauze wire cloth, form by steel wire or steel cable braiding, and form by a plurality of networks unit, it is characterized in that: one side any of described network unit is the arc limit, the radian on arc limit is 0.610 to 0.697, in the network unit wherein the angle on both sides be the 55-60 degree, the inscribed circle diameter between the network unit is 65 millimeters.
The end of two free margins in described any one network unit, end all is bent to form behind the ring-type joint and is wound in self at least 1.5 circle, and the mutual solderless wrapped connection of ring-type joint of two free margins.
Described steel wire or steel cable are 3 millimeters of diameters or 4 millimeters, the hot-dip galvanizing steel wire that tensile strength 1770MPa is above.
Advantage of the present utility model is:
1, because the utility model adopts any limit of network unit to be set to the arc limit, when gauze wire cloth is subjected to external impacts, compare for the straight flange form with existing network unit, the arc limit has initial radian, for flexible contact, has certain buffer distance when contacting with the face of land like this with ground surface; The steel wire stress deformation, the radian on arc limit from large to small, the cover width of gauze wire cloth also from large to small, thereby a diamond-shaped element of gauze wire cloth has had above variation when absorbing impact force, prevents that to greatest extent impact force is to the spontaneous destruction of causing of gauze wire cloth.
2, since the utility model adopt the end of two free margins in the network unit, end all to be bent to form behind the ring-type joint and be wound in self at least 1.5 circle, and the mutual solderless wrapped connection of ring-type joint of two free margins, such knotting mode is only compared in the end bending mode once of steel wire with existing, reached the purpose that equates with the intensity of net centre at two edges of steel cord end or whole net, and steel wire or steel cable more are difficult for slippage.
3, the utility model adopts 3 millimeters or 4 millimeters of diameters, the hot-dip galvanizing steel wire that tensile strength 1770MPa is above, intensity height, the further effectively application life that guarantees whole gauze wire cloth.
Description of drawings
Below in conjunction with specification drawings and specific embodiments the utility model is described in further detail, wherein:
Fig. 1 is an overall structure schematic diagram of the present utility model
The arcuate structure schematic diagram on any one limit, network unit when Fig. 2 is not stressed

The specific embodiment
Embodiment 1
With reference to Figure of description 1, high-strength flexible bank protection gauze wire cloth, form by steel wire or steel cable braiding, and form by a plurality of networks unit 1, any one side of described network unit 1 is arc limit 2, the radian on arc limit 2 is 0.645, in the network unit 1 wherein the angle on both sides be 60 the degree, the inscribed circle diameter between the network unit 1 is 60 millimeters.The related high strength bank protection flexible steel wire host of the utility model will be used for side slope protection and go deep into the engineering that soil is implemented greening again, earlier a steel wire is bent into a plurality of " it " font, another root steel wire is bent into " it " font too and guarantees these two steel wire solderless wrapped connections together, form a plurality of networks unit 1, the 3rd, four, N wire rope also adopts common mode, form a big gauze wire cloth at last, the end of two free margins in described any one network unit, end 1 all is bent to form ring-type joint 3 backs and is wound in self 2.5 circle, and the ring-type joint 3 mutual solderless wrapped connections of two free margins.Described steel wire or steel cable are 3 millimeters of diameters, the hot-dip galvanizing steel wire that tensile strength 1770MPa is above.
As R0 among Fig. 2.Be not subjected at gauze wire cloth under the situation of tension force, be generally the net sheet and cover on the burnishing surface, promptly when stress not, 1 every limit, above network unit all has original radius value R0.Local or all distortion of gauze wire cloth when system is subjected to external impacts, steel wire is enlarged to R0 ' at its radius of stressed back by R0, cover width is enlarged to A0 ' by A0, through test, radian is not 0.610 to 0.697 under the stress, the concentric circles angle is that 37 degree are to 40 degree, under the stress, along with stressed increase radian is decreased to 0 gradually by initial radian, thereby, prevent that to greatest extent impact force is to spontaneous destruction of causing owing to be subjected to that there has been above variation a network unit 1 of power gauze wire cloth when absorbing impact force after the external impacts.
The utility model is not limited to the foregoing description; description according to the foregoing description; those of ordinary skill in the art also can make some conspicuous changes to the utility model; for example; the end of two free margins is bent to form the number of turns that is wound in self behind the ring-type joint 3 is made as 1.5 circles; 3 circles; 4 circles or more; perhaps the diameter with steel wire or steel cable changes 4 millimeters into; perhaps in the network unit wherein the angle on both sides be 55,56,57,58,59 degree etc., but these changes all should fall within the protection domain of the utility model claim.
