A kind of geotechnical cell and the preparation method of the geotechnical cell

Abstract

The invention discloses a geocell, which comprises a plurality of geocell sheets and a plurality of clip slots, the geocell sheets are arranged horizontally and symmetrically in pairs, and the joints of adjacent geocell sheets are connected by cable ties and clips. The grooves are double-fixed and connected, and after the combination, the geocells are regular hexagons arranged uniformly, the grooves are C-shaped grooves, and barbs are provided at the bottom of the grooves. The geocell is a simple and efficient connection method, which solves engineering problems such as low strength and poor connectivity of the geocell.

Description

technical field [0001] The invention relates to a geotechnical cell and a preparation method of the geotechnical cell. Background technique [0002] The working principle of the geocell is to transmit the force to each connection through the cell sheet, and then transfer the force to the adjacent cell sheet from each connection, so that the geocell as a whole acts as a reinforced material to resist the external force. . It can be seen that the relative stability of the shape and material of the geocell is particularly important. The stability of the shape of the geocell mainly depends on the strength of the connection; the stability of the material of the geocell mainly depends on the compressive and shear strength. . [0003] Today's geocells are mainly divided into two categories: the first type is traditional geocells welded by unstretched polymer sheets; the second type is welded by stretched polymer sheets through insertion Connected and riveted. [0004] The disadv...

Problems solved by technology

[0004] The disadvantage of these two types of geocells is that the connection of the cell sheets is relatively weak

The first type has low compressive and tensile strength; the second type cannot achieve the same characteristics of isotropic strength because the connection cannot be welded after stretching, and the tensile strength (pull-off strength) in the positive direction is low.

[0005] In practical engineering applications, after the geocell is laid flat, when the medium is filled and the dynamic load is applied, it is easy to experience uneven stress

If the strength of the geocell connection is too low or the material is too soft, it is easy to cause problems such as lodging or serious deformation during the construction process.
