Abstract

PROBLEM TO BE SOLVED: To provide a uniform sandbag by making the sandbag shape rectangular.
SOLUTION: After inserting the insert material into the earthen bag, the bag mouth is closed with a ring stitch to form a rectangular earthenware bag. When a rectangular shaped sandbag is laid down, the gap between adjacent sandbags is reduced and the filling is greatly reduced.
Even if a pressing force is applied to the chain stitch with stretch characteristics, the sandbag is not damaged, and a stable sandbag can be provided easily.

Description

  The present invention relates to a sandbag used for civil engineering work, disaster prevention, disaster recovery, and the like.

  For sandbags that are commonly used, after putting the filling material into the sandbag, draw the string through the bag mouth, draw it into a drawstring, and turn the cord into the bag mouth 2-3 times. Used with the bag mouth closed.

Problems that the device tries to solve

  In such conventional sandbags, the string attached to the bag mouth is drawn and closed to close the bag mouth, so that there is a dimensional difference between the bottom and the top, as shown in FIG. If you want to lay them evenly, if you put them side by side, the gap between the adjacent sandbags will widen as shown in Fig. 4, and if you pile up, it will be unstable, and you will have to do other work such as padding when laying There is a problem.

Means to solve the problem

  In the present invention, after putting the insert material in the sandbag, the bag mouth of the sandbag is closed by sewing, and the shape is made rectangular. Closing the bag mouth by ring stitching has the feature that the seam extends, so that the rectangular shape can be kept constant without damaging the sandbag even if pressure is applied.

Effect of device

  As shown in Fig. 3, the sandbag of the present invention has a rectangular shape, so when it is spread evenly, such as civil engineering work, as shown in Fig. 5, the gap between adjacent sandbags is reduced, so Work is reduced. In addition, since the shape is constant in the construction to be piled up, it can be piled up stably and easily and safely, and the strength is increased by the feature that the seam of the chain stitch is extended, so it can be used for civil engineering work, foundation work, etc. preferable.

  FIG. 4 is a diagram in which conventional sandbags are laid out. FIG. 5 is a diagram in which the bag mouths of the present invention are lined with closed sandbags closed by ring stitching.

  The sandbag of the present invention is suitable for strengthening construction of soft ground when constructing factories, houses, machine plants, revetments, retaining walls, etc.

  In particular, when construction works on roads where large vehicles frequently pass, such as national roads, and when it is applied in the vicinity of residential areas, if used for foundation work before laying asphalt, vibration will be greatly reduced and vibration pollution will be prevented. Suitable for

  In the case of a predictable disaster, typhoon, abnormal tide level, etc., sandbags are pre-stacked in the assumed area, but in this case, the sandbag of the present invention can be easily stacked because the shape is stable. So it is suitable for advance disaster prevention.

  A commercially available sandbag.   A traditionally constructed sandbag in the shape of a drawstring with a drawn bag mouth.   A rectangular sandbag with a rectangular shape, with the bag mouth closed by ring stitching.   The figure which laid the sandbags of the shape of a conventional drawstring. Since the shape is not constant, there can be a large gap between adjacent sandbags.   The figure which laid the sandbag of the shape of the shape of a rectangle of the present invention in order. Since the shape becomes rectangular by ring stitching and the dimensions can be made uniform, there are few gaps between adjacent sandbags.
