Embodiment 1

[0026] Example 1 Such as figure 1 , 4 , as shown in 5:

[0027] A honeycomb-stabilized geocell, comprising a stretched polymer sheet: the surface of the cell sheet 2 is provided with parallel to each other along the width direction of the cell sheet, equidistant, and the width of the cell sheet, etc. The damping block 1 protruding from the surface of the cell sheet 2 is long and protruding, and the damping block 1 and the cell sheet are simultaneously pressed continuously at one time to form a cell sheet with damping blocks combined with equal-spaced damping blocks; the entire geocell adopts two More than one cell sheet 2 is laminated or the entire cell sheet 2 is folded.

[0028] The damping blocks 1 at the same position on the adjacent two layers of cell sheets 2 face each other, and the top surfaces are in contact. The top surfaces of the damping blocks 1 are connected in groups to form connecting joints 3 to form geocells. After unfolding, the shape of the honeycomb ce...

Embodiment 2

[0029] Example 2 Such as figure 1 , 4 , Shown in 5: a kind of geocell with damping block, it presses as follows Figure 4 , 5 In the shown method, the entire stretched cell sheet 2 is folded and welded in six layers, and each layer has three welding points. The stretched cell sheet 2 has a width of 100 mm and a thickness of 0.6 mm. The height of the two surfaces of the protruding cell sheet of the damping block 1 is 2.5 mm, and the protruding width is 13 mm. 400mm. Such as Figure 5 As shown, the damping blocks on two adjacent cell sheets face each other, the top surfaces are in contact, and are welded in groups to form a connecting seam 3 . After the geocell is expanded, the shape of the honeycomb cell is figure 1 The rhombus shown. When the entire cell sheet is folded, the head and tail damping block 1 should be reserved to facilitate the connection between the geocells.

[0030] The shape of the cross-section of the damping block 1 includes trapezoid, square, rect...

Embodiment 3

[0031] Example 3 Such as figure 2 , 3 Shown: the damping block 1 described in Embodiment 1 has double-sided symmetrical protruding cells or single-sided asymmetrical protruding cells.

Abstract

The invention relates to a geocell with stable honeybee lattices. The surface of each geocell sheet is provided with damping blocks, the damping blocks are mutually parallel, are arranged at equal intervals in the width direction of the geocell sheet, have the length identical to the width of the geocell sheet and are projected out of the surface of each geocell sheet, the damping block and the geocell sheets are synchronously and continuously pressed in one step to become the geocell sheets combined into a whole with the equidistant damping blocks; the whole geocell adopts more than two geocell sheets to be laminated or the whole geocell sheet to be folded; according to the whole geocell sheet folding, the geocell sheets with the damping blocks are folded into more than two layers in the length direction, the damping blocks arranged on the two adjacent geocell sheets are pairwise opposite and are connected every two groups, connecting seams are formed, the honeybee lattices are rhombic after the unfolding, and the geocell is manufactured. The geocell has the advantages that 1, stretched polymer sheets are adopted, and the intensity of the geocell sheets is high; 2, the damping blocks are arranged at connecting parts of the geocell sheets, the identical intensity of the connecting parts in all directions is ensured by a damping block connecting method, and the pulling-out intensity is raised to be identical to the peeling intensity; 3, the damping blocks have greater contact surfaces, the connecting intensity is high, and the connecting seams are firm.

Description

technical field [0001] The invention relates to a geotechnical building material, in particular to a geotechnical cell with stable honeycomb cells. Background technique [0002] Geocell is a very widely used geotechnical material. Geocell is composed of multi-layer polymer sheet strips called cell sheets, or the whole strip is repeatedly folded into several layers, and connected alternately according to certain rules. The three-dimensional grid structure is formed after two layers of cells are adjacent to each other. The cross-section of a single grid generally has a circular, hexagonal, rhombus, and triangular shape, which are collectively referred to as honeycomb cells. [0003] The geocell transmits the force to the connection through the cell sheet, and then transmits the force to the adjacent cell sheet from the connection, so that the cell as a whole plays the role of confinement and reinforcement. In this process, it is very important to maintain the relative stabili...
