Description

Technical Field

[0001] This utility model belongs to the field of geocell technology, and specifically relates to a hexagonal welded geocell. Background Technology

[0002] Geocells are mesh-like cell structures formed by strong welding or riveting of wide strips of high-strength HDPE or PP copolymer. They are flexible and can be folded up for transport and unfolded and filled with soil or concrete when needed, creating a structure with strong lateral confinement and high rigidity. They can be used as a subbase to treat weak foundations and increase their bearing capacity, laid on slopes to form slope protection structures, and used to construct retaining structures. Currently, most geocells are made by bending multiple sheets and welding them at the bending points of adjacent sheets. The external forces acting on the sheets are relatively concentrated, and the number of weld points between the sheets is small and limited, resulting in lower strength tolerance. Damage to even one weld point can affect the overall strength of the entire geocell. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a hexagonal welded geocell.

[0004] This utility model is achieved through the following technical solution:

[0005] A hexagonal welded geocell includes several longitudinal sheets, characterized in that: the bends of adjacent longitudinal sheets are respectively connected to a first micropile and a second micropile, the first micropile and the second micropile are connected to a transverse sheet, and two welds are respectively provided between the first micropile and the longitudinal sheet, between the first micropile and the transverse sheet, between the second micropile and the transverse sheet, and between the second micropile and the longitudinal sheet.

[0006] Furthermore, the longitudinal sheet extends into the first fan-shaped groove of the first micropile, the transverse sheet extends into the first strip-shaped groove of the first micropile, the transverse sheet extends into the second strip-shaped groove of the second micropile, and the longitudinal sheet extends into the second fan-shaped groove of the second micropile.

[0007] The beneficial effects of this utility model are: the geocell adopts a hexagonal shape, which can disperse external forces in multiple directions, and each connection has two welds. Even if one of the welds is damaged, the overall structure can still be maintained without damage, which greatly enhances the strength of the geocell, makes its service life longer, and ensures the long-term stability of geotechnical engineering.

[0010] Appendix Figure 2 This is a schematic diagram of the layout of this utility model;

[0011] In the figure, 1 is the longitudinal sheet, 2 is the first micropile, 3 is the second micropile, 4 is the transverse sheet, 5 is the weld, 6 is the first fan-shaped groove, 7 is the first strip groove, 8 is the second strip groove, and 9 is the second fan-shaped groove. Detailed Implementation

[0012] The attached figure shows a specific embodiment of this utility model. This embodiment includes several longitudinal sheets 1. Adjacent longitudinal sheets 1 are connected at their bends to first micropiles 2 and second micropiles 3, respectively. A transverse sheet 4 connects the first micropiles 2 and the second micropiles 3. Two welds 5 are provided between the first micropiles 2 and the longitudinal sheets 1, between the first micropiles 2 and the transverse sheet 4, between the second micropiles 3 and the transverse sheet 4, and between the second micropiles 3 and the longitudinal sheets 1, respectively. The longitudinal sheets 1 extend into the first fan-shaped groove 6 of the first micropiles 2, the transverse sheet 4 extends into the first strip-shaped groove 7 of the first micropiles 2, the transverse sheet 4 extends into the second strip-shaped groove 8 of the second micropiles 3, and the longitudinal sheets 1 extend into the second fan-shaped groove 9 of the second micropiles 3.

[0013] The hexagonal welded geocell of this invention consists of two bent sections of two adjacent longitudinal sheets 1 and two transverse sheets 4 forming a hexagon of equal length. The hexagon is filled with soil or rock, which can disperse external forces in multiple directions. Two welds 5 are welded between the transverse sheet 4 and the first micropile 2 and the second micropile 3, respectively. Two welds 5 are also welded between the first micropile 2 and the longitudinal sheet 1, and between the second micropile 3 and the longitudinal sheet 1, respectively. This makes the overall structure more stable and maintains the stability of the overall structure even if one weld 5 is damaged. Furthermore, the transverse sheet 4 extends into the first strip groove 7 of the first micropile 2 and into the second strip groove 8 of the second micropile 3, while the longitudinal sheet 1 extends into the first fan-shaped groove 6 of the first micropile 2 and into the second fan-shaped groove 9 of the second micropile 3, respectively. This increases the contact area between the longitudinal sheet 1 and the first micropile 2 and the second micropile 3, and also increases the contact area between the transverse sheet 4 and the first micropile 2 and the second micropile 3, further ensuring the strength and stability of the overall structure.
