PURPOSE:To raise the coating density of concrete as well as prevent the occurrence of dust by a method in which ready-mixed concrete is supplied from the tip opening of a supply tube to the periphery of a rotary brush and applied to the surface of wall by rotating the brush. CONSTITUTION:A supply tube 2 is supported by a multi-joint manipulator to enable it to move aptly to faces to be constructed, such as wall face, tunnel excavated face, etc. Ready-mixed concrete C is supplied from the supply port 21 of the tube 2 to the tip opening 22 of it. A rotary brush 5 radially planted with flexible brushes 52 consisting of stainless steel wire having great durability is then turned around the shaft 51. The concrete C supplied to the inside of the rotary periphery of the brushes 52 from the opening 22 is applied to the face 10. Since the concrete can be exactly pressed to raise the coating density due to the snapping action of the brush 5 and the occurrence of dust can also be prevented.
