TAMPING ROLLER AND ROLLING AND TAMPING EXECUTION METHOD IN BANKING CONSTRUCTION

PURPOSE:To improve in quality by providing an projecting a pad to the peripheral surface of a roller provided to the rear of a frame so that it is capable of swiveling and inclining the front and rear in the direction of the rotation with specific angles to form sides vertically at right angles to them. CONSTITUTION:A pad 4 is provided and projected to the peripheral surface of a roller 3 mounted to the rear of a frame 2 capable of pulling by a bulldozer so that it is capable of swiveling, and the front 4A and the rear 4B have their own inclinations with specific angles to form right and left sides 4c vertically at right angles to the inclinations. When enbankment is built in a peat poor subsoil, a high humidity wetted soil filling material is laid uniformly with a specific thickness of layer, and it is repeated several times to roll and tamp it by means of a turbine roller 1. The filling material is constituted of a normal soil having a moisture content ratio of 20-30% and a high humidity wetted soil of 35-50%, layer thicknesses are respectively 0.3-0.5m, and rolling and tamping actions are repeated proper times. According to the constitution, vibration and floating water phenomenon can be prevented.
