Problems solved by technology
[0003] When the geocell is used to build the retaining wall, the exposed part of the geocell is a curved surface. Under the action of light aging, stress fractures are prone to occur at the joints of the cells. In addition, the curved surface structure of the exposed part is not conducive to the later stage. maintenance of the retaining wall, in order to solve the above problems, provide a stable structure, the exposed part is not easy to break the geocell applied to the retaining wall, the present invention provides the following technical solutions

Embodiment Construction
[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0028] A geocell for retaining walls such as Figure 1-Figure 4 As shown, it includes a mesh cell 1 and an outer panel 2, and the mesh cell 1 and the outer panel 2 are fixedly connected by a connecting piece 3;
[0029] The mesh cell 1 is formed by a group of geocell sheets 11 with openings on the surface, which are interlaced and fixed face to face. When stretched in a direction perpendicular to the geocell sheet 11, a honeycomb network structure can be formed. ,
[0030] The fixing method between the two geocell sheets 11 is one of w...

The invention discloses a geocell for an earth retaining wall. The geocell for an earth retaining wall comprises a net-type geocell and an outer side panel. The net-type geocell and the outer side panel are fixedly connected through connecting pieces. The geocell is of the structure that the traditional net-type geocell and the outer side panel are fixedly connected through the connecting pieces.When the the geocell is used for constructing the earth retaining wall, the exposed part of the geocell is a flat plate structure. Thus, the geocell has no stress concentration point and is not proneto breakage. Moreover, a smooth structure of the outer side panel facilitates later maintenance of the earth retaining wall by working staff. The net-type geocell and the outer side panel are movablyconnected through the connecting pieces, and transfer transportation and field installation of the net-type geocell and the outer side panel are facilitated.
Description
technical field [0001] The invention belongs to the field of civil engineering construction devices, and in particular relates to a geotechnical cell used for retaining walls. Background technique [0002] Geocell is a three-dimensional mesh cell structure, which can be expanded and contracted freely, and can be collapsed during transportation. It can be stretched into a mesh during construction, and filled with loose materials such as soil, gravel, concrete, etc., to form a strong lateral restriction and high rigidity. A retaining wall refers to a structure that supports the subgrade fill or hillside soil and prevents the deformation and instability of the fill or soil. The use of geocells to build retaining walls is currently a commonly used construction method. [0003] When the geocell is used to build the retaining wall, the exposed part of the geocell is a curved surface. Under the action of light aging, stress fractures are prone to occur at the joints of the cells. I...
