Abstract

PURPOSE: To apply easily a high density material in a thin layer in a constructing work irrespectively of the material, shapes, inclinations, etc. of the working objects by mixing and spraying a mixture added with cement, sand and a waterproofing agent with a gun by means of compressed air and pressure water.
CONSTITUTION: A mixture obtained by putting cement and sand compounded at about 1:2.5 volume ratio into a mixer, adding about 2W10% a waterproofing agent (for example, of silica base such as sodium silicate) based on the weight of the cement, and thoroughly mixing these is put into the upper and lower chambers 1, 2 of a cement gun body, then a cone valve 3 is closed to apply pressure, and a material supply impeller device 5 is driven by an air motor 6 under desired pressure to discharge the mixture through a discharge pipe 8 having a valve 8a. On the other hand, pressure water is fed into an annular groove 11a through a through-hole 11b of a head body from a flexible pipe 15, and enters the multiple slant holes 12a pierced in an annular body 12 through the groove 11a, thereby discharging the mixture in the central direction in an injection pipe 13.
