Title:
NOZZLE FOR BLOWING MORTAL OR CONCRETE AND APPARATUS FOR FORMING SLOPE FACE PROTECTION IN ALTITUDE SLOPE FACE USING THE NOZZLE
Document Type and Number:
Japanese Patent JP3904449
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the structure of a nozzle to enable to intimately mixing an admixture added to rapidly harden a blowing material injected into a forming frame with compressed air in a slope face protection work in the nozzle for blowing mortal or concrete, and an apparatus for forming a slope face protection in an altitude slope face using the nozzle.
SOLUTION: A circular material supply hose connection port (2) is formed on the base end of a nozzle body (1). A small chamber (1") separated from a nozzle body chamber (1') for the nozzle body is provided in the mid-way of the nozzle body in the longitudinal direction and an introducing pipe (3) for introducing the admixture and the compressed air is connected to an introducing port of the small chamber, a slit like discharge port (8) communicating with the nozzle body chamber (1') is formed in the tip of the small chamber (1") and a jetting port (9) in the tip of the nozzle body chamber (1') is formed flat.
