This concrete supply can also be used as the above-mentioned fluid ejection holes 6, and is suitable when using fresh concrete having good fluidity. Further, as shown in FIG. By dividing the blade portion 3 that is a small chamber 4 of one block into a small chamber 4a for fluid and a small chamber 4b for ready-mixed concrete, the fluid and ready-mixed concrete can be jetted separately. The jet holes 6b drilled in the small chamber 4b of ready-mixed concrete are the small chambers of fluid.
If it is formed with a diameter larger than 6a, its fluidity is improved.
