SANDBAG FOR FORM IN CIVIL ENGINEERING WORK AND CIVIL ENGINEERING WORK USING IT

PROBLEM TO BE SOLVED: To improve the workability by filling up a main bag and a plurality of auxiliary bags provided at the outer periphery with mortar as a filler. SOLUTION: A sandbag 110 for civil engineering form is constituted with a main body 118 and small sandbags 120 such as two or the like provided at the facing positions on the outer periphery of the main body which are filled up with mortar 114. Next, a mortar filling opening portion 119 and a tying portion 12t having a tying body 122 are formed, and a reinforcing belt 130 is provided around the whole periphery of a side portion to the mortar filling height h1, a bottom reinforcing portion 126 consisting of a cross-shaped band body 124 and suspending belts 128. At the time of work, a plurality of sandbags 110 are fixed so as to overlap the sandbags 120 each other at the upstream side and the downstream side of a base for a sediment control dam, concrete is poured between sandbags, and the sandbags are stacked up and the same work is repeated. Also as required, a remote operation means is provided for carrying the sandbags including cables, hoists or the like. In this way, the stability of sandbags and the strength of the completed structure can be greatly improved.
