PURPOSE:To construct an embankment free of subsidence at its central part by a method in which soil and sand are heaped on a net spread over the ground by leaving the side portion of the net in blank, the soil and sand in the blank portion are covered from side to upside to form a foundation banking, and the foundation banking is orderly formed in a laminating manner. CONSTITUTION:A net 1 is spread over the ground of construction site for road, dam, etc., and soil 4 is banked in a fixed thickness on the net 1 by leaving both sides of the net 1 in blank 3. The blank portions 3 are folded inwards to cover the whole of the soil 4 from side to upside to form a foundation banking (a) for the first stage. The foundation banking (b) for the second state is likewise formed on the banking (a), and subsequent foundation bankings are then orderly formed in a stacking manner. since the soil 4 is covered with the net 1, not only both sides but also the central part of the embankment can be strengthened and the subsidence of the central part can be exactly suppressed. |
