There is following technological deficiency in use in current existing steel plastic geogrid：1. grid belt and grid belt it Between by being welded together, it is high due to there was only welding stress between grid belt and grid belt when by level to load Strong steel wire does not play a part of tension, so node peeling force very little, grid node easily disconnects, so as to destroy the geotechnological lattice of steel modeling The overall structure of grid；2. its joint structure of steel plastic geogrid is not firm enough, bears level limited to weight bearing power, it is impossible to effectively Control the lateral sliding of the soil body.
Utility model content
There is provided a kind of high-strength node steel plastic geogrid in view of the shortcomings of the prior art the utility model, it is to avoid grid Fracture and soil body lateral sliding problem easily occur for node.
The utility model is achieved by the following technical solution there is provided a kind of high-strength node steel plastic geogrid, a kind of High-strength node steel plastic geogrid, it is characterised in that：Longitudinal grid belt and horizontal grid belt including integrated injection forming, institute Stating longitudinal grid belt includes the longitudinal high tensile steel wire being located inside grid belt and the high-density polyethylene being coated on outside high tensile steel wire Alkene outer layer；The horizontal grid belt includes the horizontal high tensile steel wire being located inside grid belt and the height being coated on outside high tensile steel wire Density polyethylene outer layer；The bottom surface of the horizontal grid belt and longitudinal grid belt in the same plane, longitudinal high tensile steel wire It is that upper lower leaf is set with horizontal high tensile steel wire, its spacing distance at the middle and upper levels between lower floor is more than the straight of high tensile steel wire Footpath；The horizontal grid tape thickness is more than longitudinal grid belt.
Preferably, the quantity of the longitudinal high tensile steel wire in the upper strata is 4, the quantity of lower floor's longitudinal direction high tensile steel wire is 4.
Preferably, the quantity of the horizontal high tensile steel wire in the upper strata is 4, the quantity of lower floor's transverse direction high tensile steel wire is 4.
Preferably, the longitudinal high tensile steel wire in the upper strata be located at the horizontal high tensile steel wire of the horizontal high tensile steel wire in upper strata and lower floor it Between.
Preferably, the horizontal grid belt is identical with longitudinal grid bandwidth.
Preferably, longitudinal grid belt and horizontal grid belt surface are evenly arranged with groove.
Preferably, the channel section is shaped as triangle.
The beneficial effects of the utility model are：
1st, longitudinal grid belt and horizontal grid belt is combined together by way of injection, eliminate welding process, work as incident During by level to load, integral structure transverse direction high tensile steel wire can play drawing-resistant function, therefore avoid knot after soldering Point peeling force is small, the defect easily disconnected；Enhance structural strength and stability.
2nd, at longitudinal grid belt and horizontal grid belt node horizontal high tensile steel wire with longitudinal high tensile steel wire is stacked places, with Just load is more effectively transmitted, while making node structure more firm, lifting bears level to weight bearing power.

Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, this programme is illustrated.
As shown in Figure 1, 2, the utility model includes the longitudinal grid belt 2 and horizontal grid belt 1 of integrated injection forming, institute Stating longitudinal grid belt 2 includes being located at longitudinal high tensile steel wire 4 that increase intensity effect is played inside grid belt and is coated on high-strength steel High density polyethylene (HDPE) outer layer outside silk.The horizontal grid belt 1, which includes being located at, plays increase intensity effect inside grid belt Horizontal high tensile steel wire 3 and the high density polyethylene (HDPE) outer layer being coated on outside high tensile steel wire.The horizontal grid belt 1 and longitudinal grid With 2 bottom surface in the same plane.Change between conventional grid belt and grid belt by way of being welded together, lead to Crossing the mode of injection makes longitudinal grid belt 2 and horizontal grid belt 1 combine together, eliminates welding process, when by level to lotus During load, integral structure transverse direction high tensile steel wire 3 can play drawing-resistant function, therefore avoid the postjunction peeling force of soldering Defect that is small, easily disconnecting；Enhance structural strength and stability.
Longitudinal high tensile steel wire 4 and horizontal high tensile steel wire 3 are that upper lower leaf is set, and it is at the middle and upper levels between lower floor Spacing distance is more than the diameter of high tensile steel wire.In prioritization scheme, the quantity of the longitudinal high tensile steel wire 4 in the upper strata is 4, and lower floor indulges It it is 4 to the quantity of high tensile steel wire 4.The quantity of the horizontal high tensile steel wire 3 in the upper strata is 4, the number of lower floor's transverse direction high tensile steel wire 3 Measure as 4.In order to realize optimal vertically and horizontally transmission force property, the longitudinal high tensile steel wire 4 in the upper strata is located at the horizontal high-strength steel in upper strata It is laterally high-strength at longitudinal grid belt 2 and the horizontal node of grid belt 1 the purpose is to realize between the horizontal high tensile steel wire 3 of silk 3 and lower floor Steel wire 3 and the stacked placement of longitudinal high tensile steel wire 4, more effectively to transmit load, while making node structure more firm, are carried Rise and bear level to weight bearing power.
The thickness of horizontal grid belt 1 is more than longitudinal grid belt 2, and horizontal grid belt 1 is identical with longitudinal width of grid belt 2. Longitudinal grid belt (2) and horizontal grid belt (1) surface are uniformly arranged fluted 5, and the cross sectional shape of groove 5 is triangle Shape.Because the thickness of horizontal grid belt 1 is higher than longitudinal grid belt 2, and grid belt surface is provided with uniform groove 5, and both coordinate Increase interlocking, the interlocking of GSZ and the soil body so that the coefficient of friction between the soil body and grid becomes big, and then ground Steadiness enhancing, the lateral sliding of the soil body controlled.
