PURPOSE:To improve the strength of in-plate concrete pile by avoiding the intermixture of slime by a method in which a concrete-housing bag wherein the concrete placing port of a concrete placing tube is positioned is set on the bottom of a pit excavated and concrete is placed. CONSTITUTION:A reinforcing bar cage 5 is inserted into an excavated pit B, and a concrete-housing bag 1 hung down by a hanging tool 3 is covered on the downside of the concrete placing port (a) of a concrete placing tube 2. Concrete is supplied into the bag 1. The bag 1 is set with the tube 2 on the bottom of the pit B through the cage 5, the tool 3 is loosened, the concrete is supplied into the bag 1 from the port (a) of the tube 2 and the concrete is placed up to the ground's surface of the pit B. In-plate piles containing lesser amount of slime and having excellent strength can thus be formed. |
