INNOVATION POLYMER TAPE (VERSIONS) AND TAPE MADE OF IT Russian patent published in 2013 - IPC E01C3/00 E02D17/20 E02B3/12 

FIELD: construction.

SUBSTANCE: invention is designed to manufacture space-polymer lattices (SPL) used to reinforce building structures and weak bases of industrial and civil facilities, slopes of coastal lines and beds of water reservoirs, in construction of aerodromes, road surfaces, slopes, retaining walls. The tape may find application in other construction industries required higher and stable indices of strength and durability of erected facilities. The proposed flexible polymer tape for production of a space polymer lattice (SPL), preferably on the basis of polyethylene, comprises reinforcing threads in longitudinal direction selected from the group that includes the following: aramid threads or threads from carbon fibres, or threads of ultrahighmolecular polyethylene (UHMPE). Holes of perforation are arranged between reinforcing threads, are made with a lengthy shape stretched along the reinforcement direction, and have a rounded shape at the ends. The tape has thickness of 1-2 mm and texture on the outer surface, which is characterised by availability of ledges with height of 0.2-0.4 mm. During production of the space polymer lattice, in particular, a geogrid, they use flexible polymer strips, which are produced by means of metre cutting of the above specified polymer tape comprising reinforcing threads.

EFFECT: higher stability of geometric dimensions, higher strength and increased service life of a tape and all items made of it, higher bearing capacity of a geogrid, elimination of deformation of reinforced soil structures, increased drainage capacity of items.
