Logical strength concrete will be compressed and generate pressure, and entrance, the diameter of outlet of above-mentioned injection guiding body 71 are more than central part
Diameter.
Also, as shown in Figure 11 to Figure 12, when the central part via above-mentioned injection guiding body 71 to diameter more than above-mentioned
During the outlet discharge regular tenacity concrete of the injection guiding body 71 of the central part of injection guiding body 71, to radial
Mode supplied in the air supply hole 72 that forms of outer circumferential surface inclination of injection guiding body 71 more than 5 air pressures high pressure compressed it is empty
Gas makes regular tenacity concrete be formed in the outlet of injection guiding body 71 and is vortexed and sprays, above-mentioned compressed air and common strong
Degree concrete is not only unfolded in a manner of sputtering, but also when compressed air and regular tenacity concrete are unfolded in a manner of sputtering,
Compressed air and regular tenacity concrete eliminate a large amount of bubbles in regular tenacity concrete during colliding with each other, because of gas
The elimination of bubble and the slump of regular tenacity concrete is caused to decline, cause to side slope 100 discharge regular tenacity spray coagulation
Soil forms internal layer portion 200, and outstanding adhesion can be presented.
The normal concrete that it is 27MPa that table 2, which is shown to mixing intensity, and the slump is 70~80mm is mixed into per unit volume
Bubbles volume reach 20%, 27%, 33% bubble, the experimental result after being sprayed using compressor and by 9 air pressures.
As shown in FIG. 13 to 15, in the case where the bubbles volume added reaches 20%, the slump increases from the 80mm of normal concrete
The 250mm being mixed into after bubble is added to, and is reduced after being sprayed to 90mm.Reach 20% in the bubbles volume added
In the case of, the water of 6.8kg/m3 is with the addition of, still, after final injection, the slump is reduced, this is because being mixed in regular tenacity
In solidifying soil course of injection, portion of water is eliminated to air.In the case where the mixed bubbles volume of institute reaches 27% and 33%,
Since the Board Lot added is more, it is known that after spraying, although the final slump is more than collapsing for normal concrete
Degree of falling, still, unrelated with the air capacity of normal concrete or the additional air capacity that is mixed into, final constant amount of air.
