Abstract
The invention discloses a multi-directional stretching plastic geogrid and a manufacturing method thereof. The multi-directional stretching plastic geogrid is characterized by comprising transverse bar bundles and longitudinal bar bundles which are alternately distributed and intersected, the intersected transverse bar bundles and the intersected longitudinal bar bundles form rectangular geogrid units which continuously extend and are connected with each other, and interlaced diagonal bars are arranged in the rectangular geogrid units. The manufacturing method of the geogrid comprises the following steps of: firstly punching or extruding a hole array on a plastic plate, and then stretching the plastic plate. In the invention, multi-directional loads can be synchronously borne, the probability of tearing failure of nodes is decreased, the whole structural strength is enhanced at the same time, and the stress state is more reasonable.
Description
One: technical field
The present invention relates to a kind of geotechnological material, especially a kind of plastic tensile rectangle mesh material and manufacture method thereof, it can be used for highway, railway, waterpower, electric power, water and soil conservation etc. and strengthens with the permanent carrying ground of large tracts of land.
Two: background technology
In permanent ground reinforcement civil engineerings such as roadbed and dykes and dams reinforcement, side slope protection, hole wall reinforcement, large-scale airport, parking lot, harbour goods yard, for reaching the factor of safety and strong, durable, geo-grid must satisfy following requirement in construction:
1. increase the bearing capacity of roadbed and ground, prolong the application life of roadbed and ground.
2. prevent that the road surface from subsiding or crack, keep ground attractive in appearance neat.
3. enhancing slight slope supports the stability protection environment of side slope grass planting net pad, prevents erosion.
4. but the substituted metal net is used for false top net under the mine.
5. have enough shear resistances, and have multidirectional locking system and stability.
The civil engineering reinforcement material select the project of vital and lasting importance that is related to workmanship for use.At present, alternative material has: simple tension plastics geo-grid, biaxial tension plastics geo-grid, three-dimensional stretched plastic geo-grid, steel are moulded geo-grid and geonet etc.
The said goods is subjected to single, the simple shape of net structure.Cause the interlocking ability of gathering materials relatively poor, friction snap-in force instability between the grid and the soil body causes potential safety hazard easily, thereby the nonvolatil reinforcement of Important Project reinforced require strict especially engineering then to be restricted, it will be by many axialmodes---and multi tension plastics geo-grid replaces.
Three: summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of multi tension plastics geo-grid and manufacture method thereof, multiaxis is to (four-way) stretched plastic geo-grid, it can guarantee the stability of ground, have enough tensions, shear strength again, and can prevent soil loss and strengthened the effect that prevents subgrade settlement.
For achieving the above object, the technical solution adopted in the present invention is as follows:
A kind of multi tension plastics geo-grid, described grid has certain length and width, it comprises Cross slat cluster spaced apart and vertical bar cluster, wherein Cross slat rod and vertical bar rod are interlaced at joint, form and extend continuously and interconnected square-grid unit, the joint of square-grid unit is the node that crosses, and is provided with the diagonal bars rod in the square-grid unit, the two diagonal bars rods formation node that crosses mutually.
Above-mentioned multi tension plastics geo-grid, described square-grid unit depth-width ratio is 1: 2~2: 1.
Above-mentioned multi tension plastics geo-grid, described node is provided with lightening hole.
A kind of method of making the above-mentioned multi tension plastics of claim geo-grid may further comprise the steps:
A, go out on plastic plate or the extrusion cavities array, described hole array is arranged by some holes unit rules and is formed, and unit, described hole comprises four holes, arranges with the central point annular array in these four holes; Described regularly arranged for the unit, hole be horizontal, vertical equidistantly to around radiation launch;
B, with above-mentioned plastic plate carry out vertically, cross directional stretch.
In the above-mentioned manufacture method, each hole of unit, described hole is identical isosceles triangle hole, and the drift angle summit of isosceles triangle overlaps with longitudinal direction or transverse direction towards array center's point and its center line.
Above-mentioned manufacture method, the described vertical, horizontal that is stretched as stretches one by one.
Multiplying powers such as above-mentioned manufacture method, described transverse and longitudinal are stretched as stretch.
Beneficial effect of the present invention shows:
This multi tension plastics geo-grid provide a kind of multiaxis to the stretched plastic geo-grid, usually the stretching not care about one's appearance is by clamp clamps, and can on roller, slide, roller is perpendicular to draw direction, under the uniaxial tension situation, have only two relative not care about one's appearances to be clamped, make the tension goods produce inhomogeneous deformation; And multiaxis utilizes speed difference to realize that multipoint mode stretches to adopting multiple roll to twine coated formula, thereby has realized that the draw ratio rate of change is stable, and article construction shape homogeneous phase together.
Each node of the square-grid unit of this geotechnological grid connects eight muscle bands, the node that the formation size of node is compared other grids formation is big, its supporting capacity strengthens, simultaneously, contain the staggered node that also forms of diagonal muscle band and diagonal muscle band in this square-grid unit, the square-grid unit is divided into stable triangular element, has further strengthened the transverse and longitudinal and the oblique extension stress of grid.
This geotechnological grid adopts stretch forming process, and non-welding or braiding form, and whole geo-grid pull resistance is good, not easy fracture or the situation that occurs coming unglued.
This shows that the present invention can guarantee the stability of ground, have enough tensions, shear strength again, and can prevent soil loss and strengthened the effect that prevents subgrade settlement.
Utilize the network structure of uniqueness set forth in the present invention, can make the tensile strength height, tearing toughness is big, and is strong with soil rubble adhesion; The frictional force of grid surface and filler increases, and grid also increases the resistance of filler; Because the relation of above factor can produce bigger " snap-in force " and " build-in force ", increases its interface friction resistance, guarantees that geotechnical engineering is perfectly safe.
