摘要： A reinforced geocell is made of flexible polymeric strips arranged in rows and interconnected in a staggered order lengthwise to form a three-dimensional cell structure when stretched in the direction normal to surfaces of the strips. The strips are provided with drainage apertures and are reinforced in a longitudinal direction with reinforcing threads having at least two fibrous elements twisted along full lengths thereof. A method for producing a geocell includes extruding a polymeric material for producing a sheet material, laying out twisted reinforcing threads onto the sheet material, calendaring the sheet material when heated to 120 to 200° C. to press reinforcing threads into the sheet material, cutting a reinforced sheet material into sheets, perforating the sheets for producing drainage apertures, cutting the sheets into strips, and interconnecting the strips in a staggered order to form a three-dimensional cell structure.

摘要： Geocell structures stabilize water body shorelines and beds, slopes and retaining wall bridge abutments in such areas of construction as the oil and gas, transport and hydraulic engineering industries, amongst others. A blank for producing a weld-free geocell is made from a polymer sheet material having incisions therein in the form of segments of parallel lines. Adjacent incisions in the same row have a distance S between the ends thereof and the relationship S/L=K1, where K1 is from 0.1 to 0.5. The incisions of adjacent rows are at a distance D from each other and have the relationship D/L=K2, where K2 is from 0.1 to 0.7. At the ends of the incisions, there are openings which are oval or circular in shape. A weld-free geocell includes at least one blank stretched in a direction perpendicular to the lines of the incisions to form a three-dimensional cellular structure.
