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.

1. A blank for producing a weld-free geocell, said blank comprising: a sheet polymeric material provided with incisions, said incisions being comprised of parallel line segments, each parallel line segment having a length L, said incisions being arranged in rows, wherein incisions in adjacent rows are offset along a direction of said incisions of respective rows; andadditional openings for tendons so as to fix said sheet polymeric material in stretched state on a slope,wherein adjacent incisions in a row have a distance S between respective ends of said adjacent incisions, and wherein a relationship S/L=K1, K1 being in a range from 0.1 to 0.5,wherein said incisions in adjacent rows have a distance D from each other, and wherein a relationship D/L=K2, K2 is being in range from 0.1 to 0.7, andwherein ends of the incisions are provided with oval or circular openings, andwherein said additional openings for tendons are arranged in staggered order on parallel straight lines between the rows of the incisions, the adjacent additional openings being disposed at the distance S+L from each other in the direction longitudinal relative to the lines of the incisions and at the distance 2D from each other in the direction transverse to the lines of the incisions. 2. The blank, according to claim 1, wherein said sheet polymeric material is comprised of a strip. 3. The blank, according to claim 1, further comprising: a mesh engaged to said sheet polymeric material, said mesh reinforcing said sheet polymeric material. 4. The blank, according to claim 3, wherein said mesh is comprised of at least one of a group consisting of an aramid fiber and a carbon fiber. 5. The blank, according to claim 1, wherein K1 is in a range from 0.3 to 0.35. 6. The blank, according to claim 1, further comprising: additional drain openings. 7. The blank, according to claim 1, wherein said sheet polymeric material is texturized. 8. A weld-free geocell, comprising: at least one blank, according to claim 1, being stretched in the direction perpendicular to the lines of the incisions so as to form cells in a cellular confinement structure. 9. The weld-free geocell, according to claim 8, further comprising: at least one tendon drawn through said blank so as to fix said sheet polymeric material on a slope. 10. The weld-free geocell, according to claim 9, further comprising: at least another blank connected to said at least one blank by said at least one tendon so as to form a geotextile web section. 11. The weld-free geocell, according to claim 8, further comprising anchors engaged to said sheet polymeric material so as to fix said sheet polymeric material in a stretched state on soil. 12. The weld-free geocell, according to claim 8, further comprising: a filler contained in at least one cell, said filler being selected from a group consisting of: sand, coarse gravel, peat-sand mixture, and concrete. 13. A method for producing a weld-free geocell, comprising the steps of: providing a blank being comprised of: a sheet polymeric material with incisions, said incisions being comprised of parallel line segments, each parallel line segment having a length L, said incisions being arranged in rows, wherein incisions in adjacent rows are offset along a direction of said incisions of respective rows; andadditional openings for tendons so as to fix said sheet polymeric material in stretched state on a slope,wherein adjacent incisions in a row have a distance S between respective ends of said adjacent incisions, wherein a relationship S/L=K1, K1 being in a range from 0.1 to 0.5, wherein said incisions in adjacent rows have a distance D from each other, and wherein a relationship D/L=K2, K2 is being in range from 0.1 to 0.7;providing the ends of said incisions with the oval or circular openings,wherein said additional openings for tendons are arranged in staggered order on parallel straight lines between the rows of the incisions, the adjacent additional openings being disposed at the distance S+L from each other in the direction longitudinal relative to the lines of the incisions and at the distance 2D from each other in the direction transverse to the lines of the incisions; andstretching the sheet material in a direction perpendicular to the parallel line segments of the incisions so as to form a cellular confinement structure. 14. The method, according to claim 13, further comprising the step of: reinforcing said sheet polymeric material with a mesh. 15. The method, according to claim 14, wherein said sheet polymeric material is texturized. 16. The method, according to claim 13, further comprising the steps of: providing additional openings in said sheet polymeric material; anddrawing tendons through said additional openings so as to fix said sheet polymeric material in a stretched state on a slope. 17. The method, according to claim 13, further comprising: providing additional drain openings in said sheet polymeric material.
