METHOD FOR PRODUCING GEOGRID OF UNLIMITED LENGTH FROM SEPARATE SECTIONS Russian patent published in 2014 - IPC E01C5/20 

FIELD: construction.

SUBSTANCE: invention relates to the road and railway construction, construction of aerodromes, objects and structures for various purposes, landscape construction and can be used for the manufacture of bulk geogrids used in the development of the base of the pavement, for example, during formation of protective subballast layer of railway track. Method for manufacturing the geogrid of infinite length consists of preliminary preparation of package sections, during which the bands of each section are laid on each other and joined in transverse direction inter se by means of weld joints in staggered order, and subsequent conjugation of adjacent sections inter se. During the preliminary preparation of package sections, each pair of bands is laid with offset along the length relative to each other to form the protruding ends, and conjugation of sections inter se is carried out by overlapping the ends of strips protruding in response of adjacent sections.

EFFECT: technical result consists in simplifying the process of manufacturing the geogrid while improving simultaneously its strength characteristics.
