Description
Technical field
The utility model relates to a kind of earth work grille net that ground building courses such as highway, railway, water conservancy, water power, dykes and dams are reclaimed land from the sea, flood control use that is used for.
Background technology
Advanced nonmetallic composite, have flourish over past ten years, especially developed country is used as a big industry of develop high-tech new material to the application of advanced tencel material and complex technique thereof, has been widely used in field of civil engineering such as Aeronautics and Astronautics, quartermaster equipment exhibition area, sports equipment and bridge, tunnel, building strengthening reinforcement the nineties.Present known composite material is used three fibrids: the one, and carbon fiber plate is used commonplace, carbon fiber has excellent mechanical property and high-modulus advantage, be widely used in Aeronautics and Astronautics and structural strengthening field, but its intrinsic shear strength is low, shock resistance is poor, and the rigidity of sheet material own is difficult for the bending construction greatly, carbon fiber has good electro permanent magnetic, causes defectives such as communication signal shielding, applies widely and hamper it.The 2nd, aramid fiber reinforced plastic, it has excellent mechanical property and anti-shearing, impact strength, easily bending construction advantage.But what also have blemish in an otherwise perfect thing is water funk evil, keep in dark place and weakness such as shine, and brute force descends greatly after the immersion of aramid fiber sheet material, the illumination, so should not have water and long-term illumination field to use.Three, glass fabric, the glass fiber brute force has only 1/3rd of aramid fiber, high-tenacity polyethylene fibre 1/5th, mechanical property is low, and its rigidity is strong, frangibility, construction difficulty, and also not antiacid alkali and the illumination of non-uvioresistant can only be applicable in the low-grade composite material and make packing material.
And in the present building capital construction field, generally adopt the wire lath of working out by reinforcing bar and iron wire, and be used to carry the sedimentation load of the soil body, retrain the lateral displacement of the soil body, overcome the differential settlement of the soil body, to strengthen the supporting capacity of ground.But the grid that metal is compiled into, the mesh easy deformation, distortion back is difficult for replying, and folding volume is big, and the storage transportation is very inconvenient, and has a lot of insoluble problems at tensile strength, aspect such as corrosion-resistant, antimicrobial.
The utility model content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of high-strength earth work grille net that ground is built that is used for is provided.
In order to address the above problem the technical solution of the utility model is such:
A kind of high-strength earth work grille net is characterized in that, grid is worked out by the high-strength high-modulus polyethylene long filament.
Described grid is worked out by a plurality of high-strength high-modulus polyethylene bundles, and every bundle has the plural number thigh, and per share have plural number with long filament, and the single lattice of each of grid net are quadrangle.
Described high-strength high-modulus polyethylene bundle by plural number strand by parcel net through weaving together, per share silk 2400D～15000D, per share 240～3200 fiber filaments.
The warp-wise broadwise of described grid is all worked out with the high-strength high-modulus polyethylene bundle.
One of them works out the warp-wise of described grid or broadwise with the high-strength high-modulus polyethylene bundle, and another is to working out with the conventional polyester tow.
The skin of described grid is coated with technology glue.
Described technology glue is the PVC material.
Described technology glue is modified asphalt material.
Beneficial effect, grid described in the utility model has quite high tensile strength, highly corrosion resistant, high-wearing feature, low elongation, less creep, interlocking and the interlocking stronger to the soil body, can handle soft foundation and abrupt slope dike effectively, retrained the lateral displacement of the soil body, overcome the differential settlement of the soil body, strengthen the supporting capacity of ground greatly, improved the overall performance of ground.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of the utility model high-strength earth work grille net;
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
High-strength, high-modulus polyethylene fiber is the high-performance fiber of one of the world today's three big tec fibers (carbon fiber, aramid fiber, high-strength, high-modulus polyethylene fiber), and it has the intensity height, modulus is big, density is little, toughness is good, the various chemical substances of ability corrode and ultraviolet light shines comprehensive excellent properties such as strong.
Ultra-high molecular weight polyethylene (UHMW-PE) fiber belongs to gel spinning or gel spinning.With the difference of general fibre, just be on relative " superelevation " two words of molecular weight.Common polythene is all the same with the molecular structure of UHMW-PE, all is to be raw material by several vinyl monomers, is polymerized through catalyst.Polyethylene is a kind of thermoplastic compound (high molecular polymer), and (CH2-CH2-) n, molecular mass is in the super high molecular weight that is called more than 1,000,000 in the molecular formula writing.Conventional high-intensity fiber molecular weight is 50,000--and-30 ten thousand, the molecular weight of conventional chemical fibre approximately is 4.5 ten thousand.Though the matrix of material is identical, yet because molecular weight " superelevation ", it has given the material special performances, and particularly on physical characteristic, this also is the main cause that this fiber has high-strength and high-modulus.Polyethylene is to be " linearity " molecular structure, is the toughness thermoplastic.Owing to the big reason of molecular weight (100 ten thousand-500 ten thousand), make its special performance that has in some respects, as: high impact strength (shellproof), splendid abrasion resistance, good self lubricity (can be made into special parts), excellent low temperature resistant and chemical stability (corrosion resistance) etc.
Under request in person referring to embodiment
Embodiment 1
Referring to Fig. 1
Shown in the figure is a kind of high-strength high-modulus polyethylene grid, grid radially be the high-strength high-modulus polyethylene fiber material, broadwise is the conventional polyester fibrous material, many high-strength high-modulus polyethylene fiber bundles 1 radially and many conventional polyester fiber bundles 2 of broadwise are by being woven into nettedly through compiling and editing to loom, mesh is a quadrangle, length of side 35mm, the width of broadwise is a 2-6 rice, the radially long-distance Len req of producing as required, grid radially is packaged into round roller, lays during with convenient the use.
Every bundle high-strength high-modulus polyethylene fiber Shu Yousi thigh radially of grid gathers together, and by net 3 colligations through compiling, per share have many high-strength high-modulus polyethylene fiber silks to twist into, and per share silk 9000D is more than the ultimate tension 600KN/m of this product.
