Description
Technical field
The present invention relates to field of engineering technology, particularly belong to high strength composite earthworker's grid.
Background technique
TGXG is a kind of main geosynthetics, is with the high molecular polymers such as polypropylene, polyvinyl chloride warp
Two-dimensional mesh trellis made of thermoplastic or molding or the 3 D stereo grid screen with certain altitude, TGXG are commonly used for reinforcement
Muscle material or the muscle material of composite material of soil structure etc..Fiber is generally connected to one by way of braiding by common TGXG
Rise, in soil compaction work progress be embedded to the soil body in, by with sandy soil Interaction between particles contained in the soil body to improve soil
The coefficient of friction in internal portion, to maintain the stability and structural strength of the soil body.More grid is used in digging at present
It is made mostly of polypropylene and polyethylene, the material property of such TGXG causes its own creep coefficient larger, after reinforcement
Earth structure stability it is poor, the existing typically no intensive treatment of TGXG, grid in burial and construction be easy is broken
It is bad, lead to the loss of material and the hidden danger of structure.
Summary of the invention
The object of the present invention is to provide a kind of high strength composite earthworker's grids, overcome the deficiencies in the prior art, polyester
The core-wire layer of fiber production can effectively reduce the wriggling coefficient of grid, the matte and soil that the random stripe of protective layer is formed
Interaction between particles improve the overall stability of earth structure, and coat polyester fiber by protective layer to avoid construction plaid matching
The destruction problem of grid effectively reduces construction loss, while carbon black being added in protective layer, TGXG can be made to have fabulous
The performances such as acidproof, alkaline-resisting, corrosion-resistant and anti-aging, prolong the service life.
To solve the above problems, the technical solution used in the present invention is as follows:
High strength composite earthworker's grid, including lateral grille strip and longitudinal grid item, the transverse direction grille strip and longitudinal grid item
It intersects vertically to form multiple grids, intersection is used for fixed lateral grille strip and longitudinal grid item equipped with what is be disposably molded
Node, it is described transverse direction grille strip and longitudinal grid item be equipped be mutually perpendicular to interweave reinforcing rib, it is described transverse direction grille strip and
Longitudinal grid item is made of core-wire layer and protective layer.
Further, the lateral grille strip and longitudinal grid thickness are 4-6mm.
Further, the core-wire layer is made of polyester fiber stretched filament, and the protective layer of polyethylene and carbon black by being made.
Further, the protective layer is equipped with the random stripe of protrusion.
Further, the reinforcing rib is made of modified polypropene, and the modified polypropene is glass fiber reinforced polypropylene
Composite material.
Compared with prior art, implementation result of the invention is as follows by the present invention:
High strength composite earthworker's grid of the present invention, overcomes the deficiencies in the prior art, the core made of polyester fiber
Line layer can effectively reduce the wriggling coefficient of grid, the matte and soil particle phase interaction that the random stripe of protective layer is formed
With improving the overall stability of earth structure, and coat polyester fiber by protective layer and ask to avoid construction the destruction of grid
Topic effectively reduces construction loss, while carbon black being added in protective layer, can make TGXG have it is fabulous it is acidproof, alkaline-resisting,
The endurance qualities such as corrosion-resistant and anti-aging, prolong the service life.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the lateral grille strip structural schematic diagram of the present invention.
Specific embodiment
The present invention will be further described with reference to the examples below, but the present invention is not limited to these instances, and is being de-
Under the premise of from present inventive concept, carried out by it is any improvement be within the scope of the present invention.
As shown, high strength composite earthworker's grid of the present invention, including lateral grille strip 1 and longitudinal grid item 2,
The transverse direction grille strip 1 and longitudinal grid item 2 intersect vertically to form multiple grids, and intersection is equipped with the use being disposably molded
In the node of fixed lateral grille strip 1 and longitudinal grid item 2, the transverse direction grille strip 1 and longitudinal grid item 2 are equipped with and mutually hang down
The reinforcing rib 3 directly to interweave, the transverse direction grille strip 1 and longitudinal grid item 2 are made of core-wire layer 4 and protective layer 5.
The transverse direction grille strip 1 and 2 thickness of longitudinal grid item are 4-6mm, and the core-wire layer 4 is by polyester fiber stretched filament
Be made, for the protective layer 5 by being made of polyethylene and carbon black, the protective layer 5 is equipped with the random stripe of protrusion, it is described plus
Reinforcing rib described in strengthening tendons 3 is made of modified polypropene, and the modified polypropene is glass fiber reinforced polypropylene composite material.
The present invention can effectively reduce the wriggling coefficient of grid using the core-wire layer 4 of polyester fiber production, 5 surface of protective layer
The matte and soil particle that random stripe is formed interact, and improve the overall stability of earth structure, and wrap by protective layer 5
Destruction problem of the polyester fiber to avoid construction to grid is covered, effectively reduces construction loss, while charcoal is added in protective layer 5
It is black, it can make TGXG that there are the fabulous endurance qualities such as acidproof, alkaline-resisting, corrosion-resistant and anti-aging, prolong the service life.
