Abstract
PURPOSE:To raise the frictional force between a structure and the natural ground by a method in which one side of flexible metal nettings is fixed to a casing coupler integrated with both ends of a reinforcing bar cage, other ends of the nettings are temporarily fixed along the reinforcing bar cage, and concrete is placed into the cage. CONSTITUTION:A rectangular thin-steel plate casing coupler 22 is integrated with both ends of a reinforcing bar cage 21, and one ends of metal nettings 23 are fixed to both sides of the coupler 22 and the other ends are temporarily fixed by wires to both outsides of the cage 21. The cage 21 is set in a preceding trench excavated in the ground E, a tremie tube 3 is inserted into the cage 21, and concrete 4 is placed through the tube 3. Since the temporarily fixed part of the nettings 23 is separated from the cage 21, deformed, and comes into contact with the natural ground, the extension of the concrete to the peripheral sides of the coupler 22 can be prevented, and the frictional resistance between the structure and the natural ground can be enhanced.
