<p>[PROBLEMS] To provide a sandbag guide frame placed under the bottom of each sandbag and coupling a plurality of sandbags by arranging them. [MEANS FOR SOLVING PROBLEMS] A rectangular sandbag guide frame (10) is formed of a planar rib (11) in order to arrange each sandbag (40) placed thereon. Pins (23a, 23b) of a securing piece (20) are inserted into small holes provided in the planar rib (11) from the outside of the sandbag (40), and then the clicks (33a, 33b) of a connection piece (30) are inserted through the rectangular hole (22) of the securing piece (20) and the coupling hole (13) of the planar rib (11), thus coupling a plurality of sandbag guide frames (10) in a lattice form. Thereafter, each sandbag (40) thus coupled is packed with a material. With such a construction method, the time required for laying sandbags (40) is shortened sharply and economical effect is remarkable.</p> |
