Abstract
The utility model relates to a bidirectional plastic welding geogrid. The bidirectional plastic welding geogrid comprises multiple stretched plastic stripes, wherein the multiple stretched plastic stripes (1) are longitudinally and transversely interwoven and fixed to form a geogrid, a skin made from polyethylene plastic is wrapped at the periphery of the multiple stretched plastic stripes (1), and the cross-linked points of the longitudinally and transversely interwoven plastic stripes (1) are fixed by virtue of extruding, wire drawing, grinding and welding. As the cross-linked points of the longitudinally and transversely interwoven plastic stripes are fixed by adopting extruding, wire drawing, grinding and welding processes, the bidirectional plastic welding geogrid provided by the utility model has the advantages of saving energy, protecting the environment, increasing tension intensity, reducing volume and facilitating transportation and construction and the like.
Description
Technical field
The utility model relates to a kind of two-way Plastic Welding geotechnique lattice that are used for highway, railway, tunnel roadbed, runway, harbour, large parking lot etc.
Background technology
Along with the raising of highway in China, railway construction standard, traditional product has not satisfied highroad, the designing requirement of railway high standard, and the compound geo-grid of development novel high-strength has become inevitable.Traditional is single, double to the single vinyon band of the common employing of stretched plastic geo-grid, extrude, heat, be welded into mesh grille by plasticizing with band is crisscross, it is applied in the road, under big load or high hydraulic action, tensile strength is lower, and elongation per unit length is bigger, and elastic recovery capability is relatively poor, and the deformation of creep is big, and reversibility is low.The traditional single, double main performance index to the stretched plastic geo-grid of existing widespread usage: every linear meter(lin.m.) is 45KN/m to tensile yield power maximum value in length and breadth; The elongation at yield rate is about 10%, laterally is about 12%.
Traditional single, double to the stretched plastic geo-grid be with high molecular polymer by extruding, become plate, punch process after more vertically, cross directional stretch forms.Exist energy consumption big.Pulling force is little, and volume is big, and the transportation construction is inconvenient.
The utility model content
The utility model has designed a kind of two-way Plastic Welding geotechnique lattice, and the technical problem of its solution is traditional single, doublely to exist pulling force little to the stretched plastic geo-grid, and volume is big, and the transportation construction is inconvenient.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of two-way Plastic Welding geotechnique lattice, comprise many stretched plastic bands, the longitudinal and transverse direction of many stretched plastic bands (1) interweaves with fixing and forms geotechnological lattice, the periphery of described stretched plastic band (1) is enclosed with the crust that one deck is made by vinyon, and the interconnection node of longitudinal and transverse stretched plastic band (1) is fixed by the weldering of extruding wire drawing mill.
Further, described two-way Plastic Welding geotechnique especially portion add one deck protective screening.
This two-way Plastic Welding geotechnique lattice are single, doublely compared to the stretched plastic geo-grid with traditional, have following beneficial effect:
The utility model since the interconnection node of longitudinal and transverse stretched plastic band to adopt extruding wire drawing mill welder to plant fixing, to reach energy-conserving and environment-protective, increase tension strength, alleviate advantages such as volume and convenient transportation construction.
Description of drawings
Fig. 1: the floor map of the two-way Plastic Welding geotechnique of the utility model lattice;
Fig. 2: the longitudinal sectional view of the two-way Plastic Welding geotechnique of the utility model lattice.
Description of reference numerals:
1-stretched plastic band.
The specific embodiment
Below in conjunction with Fig. 1 and Fig. 2, the utility model is described further:
A kind of two-way Plastic Welding geotechnique lattice, comprise many stretched plastic bands 1, many stretched plastic band 1 longitudinal and transverse directions interweave with fixing and form geotechnological lattice, the periphery of stretched plastic band 1 is enclosed with the crust that one deck is made by vinyon, and the interconnection node of longitudinal and transverse stretched plastic band 1 is fixed by the weldering of extruding wire drawing mill.
Two-way Plastic Welding geotechnique especially portion adds one deck protective screening, and protective screening is used for the purpose of construction safety.
The utility model since the interconnection node of longitudinal and transverse stretched plastic band to adopt extruding wire drawing mill welder to plant fixing, to reach energy-conserving and environment-protective, increase tension strength, alleviate advantages such as volume and convenient transportation construction.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
Claims (2)
1. two-way Plastic Welding geotechnique lattice, comprise many stretched plastic bands (1), the longitudinal and transverse direction of many stretched plastic bands (1) interweaves with fixing and forms geotechnological lattice, it is characterized in that: the periphery of described stretched plastic band (1) is enclosed with the crust that one deck is made by vinyon, and the interconnection node of longitudinal and transverse stretched plastic band (1) is fixed by the weldering of extruding wire drawing mill.
2. according to the described two-way Plastic Welding geotechnique lattice of claim 1, it is characterized in that: described two-way Plastic Welding geotechnique especially portion adds one deck protective screening.
