For example, a Coanda spiral flow can be used as the air flow to effectively convey the additive through 3).

乱流領域に属する流体の運動条件下にありながらも乱流

されたものである。その生成についてはすでにこの発明
者によって提案されてもいる。Coanda spiral flow is completely different from the conventional flow or turbulent flow, which is known as the concept of fluid motion.
This was discovered by the inventor of the present invention as something that is different from turbulent flow even though it is under a fluid motion condition that belongs to a turbulent flow region. Its generation has already been proposed by this inventor.

所的変質が抑制される。In other words, the inventor of this invention discovered that when a vector in the radial direction of the pipe is added to the vector of fluid in the direction of the pipe, the fluid is twisted, a dynamic boundary layer is formed near the inner wall of the pipe based on this swirling flow, and the fluid is caused to spiral. We discovered the fact that it moves at high speed in the direction of the pipe while drawing a spiral. In such a Coanda spiral flow, the fluid moves at high speed, and due to the presence of a dynamic boundary layer, even if solid particles are present, they do not collide with the inner wall of the pipe as in the case of turbulent flow. During the process of the fluid's spiral motion, the state of the fluid is maintained uniformly, and local deterioration due to collision or contact with the inner wall is suppressed.
この発明は、このような優れた特質を有するコアンダス
パイラルフローを利用しているものである。The present invention utilizes Coanda spiral flow having such excellent characteristics.

進する。In a Coanda spiral flow generation device having such a structure, compressed air is introduced from the annular slit (12) along with the flow of concrete spraying material and additives from the inlet (16). The external air and the motion vector of the flow are combined to produce a spiral motion <17). In that case, the annular slit (
At the exit of 12), the compressed air moves in the direction of arrow α due to the Coanda effect.
The fluid moves in a streamlined manner, forming a dynamic boundary layer near the inner wall of the pipe. Further, a large negative pressure area is generated on the inlet (16) side of the annular slit (12), promoting inflow from the inlet (16).

This introduction pipe (19) is effectively used to introduce specific components such as concrete spraying materials and additives, and specific components such as steel fibers are pumped through this introduction pipe (19). Alternatively, it may be fed by means such as a screw feeder.
