Abstract

The invention relates to the technical field of geogrids, in particular to a covering node geogrid and a production process, the covering node geogrid comprises a grid body, the grid body comprises a plurality of first grid strips and a plurality of second grid strips which are arranged in a staggered mode, and covering nodes used for fixed connection are welded to the staggered positions of the first grid strips and the second grid strips. According to the geogrid, wrapping nodes are arranged at the connecting positions, the effect of obviously improving the connecting strength can be achieved, meanwhile, when the connecting problem of the geogrid is solved in the prior art, simple bundling, buckle limiting and simple welding are generally adopted for forming, and the strength of the connecting positions and deformation prevention and control of the connecting positions cannot be well guaranteed.

Description

Technical field [0001] The present invention relates to the field of geometric grille technology, in particular, to a package complex node geotechnical grid and a production process. Background technique [0002] The geogrid is one of the east-work synthetic materials, and its proportion is large in geotextile materials. At present, geogrids have been widely used in developed countries in road construction, civil engineering, large structural facilities, construction facilities, hydrological geology and environmental engineering. [0003] The geogrid can be used in different requirements, respectively, separately, isolation, filter, protective, and drainage effects or simultaneously exert two effects. There are many types of geometric grids, mainly plastic stretched grilles, steel plastic grilles, glass fiber grids, polyester parallel grids. However, the geogrid is higher for its performance, such as temperature resistance, elongation and shear and shear force, etc. There is a pr...
