Abstract (en)
[origin: EP0328425A2] A soil base material blasting nozzle (10) has a throttle shaped soil base material injection port (1) which opens into a cylinder (2) and an air intake port or ports (3) formed adjacent the injection port in the side face of the cylinder (2). The air intake port(s) (3) are used as an intake port for one or more threadlike, ropelike or tapelike continuous elements (T). In preparing a vegetation bedrock, the soil base material (M) is pumped into the blasting nozzle, and the threadlike, ropelike or tapelike continuous elements are introduced through the air intake port (3), and together they are discharged from the discharging port (7) of the nozzle (10) toward the surface to be treated to prepare a plant germinating and growing bedrock. Preferably a hydrophobic agent is introduced into the nozzle to agglomerate the base material.
