Among them, the anti-corrosion structure woven with PET material has good toughness. The present invention includes at least the bag-like structure 1. The appearance of the aforementioned bag-like structure 1 is only a schematic diagram, and is not limited to this appearance, and cannot be used as an explanatory scope that limits the technical features of the present invention.

As shown in FIGS. 1-4, the aforementioned bag-like structure 1 is a bag-like structure that is woven with various fibers and alternately woven with warp and weft using a weaving machine. The aforementioned bag-shaped structure 1 can be woven into an infinite length, but the width is limited by the maximum width that can be output by the knitting machine (the width of this embodiment is 3.6 meters and the length is 300 meters). The aforementioned bag-like structure 1 is provided with a mesh bag 10 which is in cross communication with each other. The aforementioned mesh bag 10 is formed by weaving a first knitted layer 10a and a second knitted layer 10b with each other. The net-shaped pouch 10 occupies most of the area of the bag-shaped structure 1 (as viewed from FIG. 1). Of course, according to different weaving techniques, the aforementioned mesh bag 10 can be a cross shape, an X-cross shape, or other various cross shapes, as long as it can communicate with the interior of the mesh bag 10 and facilitate fillings such as concrete No structure is necessary for filling. In addition, the mesh bag 10 of the aforementioned bag-like structure 1 can also be woven into a structure that is only partially connected to each other, or a plurality of mesh bags 10 that are not connected to each other, as long as it is a variety of fillers that are convenient for concrete and other fillings. The structure of the filling is indispensable.

As shown in FIGS. 1 to 4, a plurality of partition structures 11 are provided at the slit position and periphery of the aforementioned mesh bag 10, so that the mesh bags 10 are separated from each other into a mesh shape by the partition structure 11.
