Disclosure of Invention
The invention aims to provide a geocell with a stable bedding layer.
The technical problems to be solved by the invention are as follows:
present geotechnological check room is the penetrating structure in both ends, when side slope section uses, adopts sandy soil or sandy mixture as when filler preparation bed course, easily along with the erodeing of rainwater, the phenomenon of soil erosion appears to lead to the unable normal growth of plant to this kind of structure is when using as the road bed, if the bottom hardness is not enough, appears the difficult compaction problem of bed course very easily, leads to geotechnological check room's stability relatively poor.
The purpose of the invention can be realized by the following technical scheme:
a geotechnical grid chamber with a stable cushion layer comprises a plurality of geotechnical grid chamber sheets and a loss prevention layer, wherein the geotechnical grid chamber sheets are fixed in a face-to-face staggered mode in pairs, when the geotechnical grid chamber sheets are stretched in a direction perpendicular to the geotechnical grid chamber sheets, a honeycomb net structure can be formed, and the bottom of the honeycomb net structure is provided with the loss prevention layer;
the fixing mode between two adjacent geocell sheets comprises one of welding, riveting, buckling and injection molding connection;
the geocell sheet is prepared by processing polyolefin materials such as PP, PE or PET and the like, and the polyolefin materials have good strength and corrosion resistance;
a plurality of through holes penetrating through the geocell sheet are formed in the surface of the geocell sheet at equal intervals, and the through holes can enable flowing water to be transferred among the cells, so that the cells have good drainage;
the anti-loss layer is made of a small-aperture water-permeable fabric, so that on one hand, flowing water can pass through the anti-loss layer, on the other hand, the cushion layer can be prevented from being lost, and particularly when the sand cushion layer is made of a sand cushion layer, the water-permeable fabric comprises geotextile, woven cloth and the like;
the geocell sheet is wrapped in the anti-loss layer, the geocell sheet is fixedly connected with the anti-loss layer, and when the honeycomb net structure is formed by unfolding, the anti-loss layer is spread at the bottom of the honeycomb net structure.
The geocell sheet is of a double-layer structure, the anti-loss layer is partially folded and fixedly clamped between two layers of structures of the geocell sheet, the geocell sheet is fixedly connected with the anti-loss layer, and the anti-loss layer is spread and spread at the bottom of the honeycomb mesh structure when the geocell sheet is spread and formed into the honeycomb mesh structure.
The geocell sheet is fixedly connected with the anti-loss layer through welding, riveting, fastening or injection molding connection.
The invention has the beneficial effects that:
according to the invention, through the arrangement of the anti-loss layer, on one hand, the anti-loss layer forms a permeable layer at the bottom of the honeycomb net structure, the permeable layer can discharge flowing water in the cells in time, and meanwhile, the cushion layer can be prevented from losing, so that the packing can be more easily compacted, the cushion layer with high compressive strength is formed, the deformation of the cushion layer is reduced, on the other hand, the anti-loss layer is matched with the geocell sheet, so that the anti-loss layer can play a role in blocking and filtering through holes formed in the geocell sheet, the migration of the cushion layer material in the cells can be avoided while the water permeability is ensured, and the stability of the geocell is improved.
