Field of the Invention The present invention relates to a so-called jet grouting method, which is a high pressure jet injection mixing method. 2. Description of the Related Art A high-pressure jet-injection-mixing method is a method in which a ground structure is destroyed by strong energy obtained by applying high pressure to water, and slime is discharged to the surface of the ground, thereby causing artificial space in the ground. And a hardened material is filled to form a solid compact. [0003] Such a high-pressure jet injection mixing method is,
In the triple pipe method, a triple pipe 8 is used as shown in FIG.
The ultra-high pressure water 6 with the compressed air 3 is rotated and jetted onto the ground to cut the ground, the slime 5 is discharged to the surface, and the hardening material 7 is simultaneously filled to form a columnar consolidated body. . [0006] The construction procedure of the triple pipe method is shown in FIGS. 6 to 11. As shown in FIG. 6, a guide hole is constructed by a boring machine 10 with a casing pipe 13 having a metal crown 11 and a stabilizer 12 at the tip, As shown in FIG.
The triple pipe 8 is built in the casing pipe 13 by a truck crane or the like. [0005] As shown in FIG. 8, the casing pipe 13 is pulled out (the casing pipe may be left depending on the situation), and the column machine 14 is installed as shown in FIG. 9.
A triple pipe swivel 15 is installed at the upper end of the triple pipe 8, and compressed air 3, ultra-high pressure water 6, and hardening material 7 are injected, and the triple pipe 8 is pulled up while rotating. [0006] As shown in FIG. 10, the triple pipe 8 is pulled out and the column construction is completed. However, as shown in FIG. 11, the hole is filled. [0007] As described above, the high-pressure jet injection mixing treatment method cuts the ground with ultra-high pressure water (water jet), discharges the slime, and simultaneously uses the ultra-high pressure hardening material and the hardening material. Inject the cement milk,
Moreover, since the compressed air is also used, the muddy water containing the cement component is discharged by the air lift. In order to make up for the discharged cement, a larger amount of cement milk must be injected. An object of the present invention is to eliminate the disadvantages of the conventional example and to reduce the amount of cement injected as a solidifying material, thereby reliably reducing the amount of wastewater, and as a result, wasteful wastewater treatment is required. It is an object of the present invention to provide a high-pressure jet injection mixing treatment method that eliminates the waste and reduces the waste of the cement. According to the present invention, in order to achieve the above-mentioned object, compressed air, ultra-high pressure water and a hardening material are injected from a lower end of a triple pipe built in the ground by drilling a guide hole. In the high-pressure jet injection mixing process method, in which the triple pipe is lifted while rotating to form a columnar solidified body, the triple pipe has an interval between the injection nozzle of the ultra-high pressure water and the injection nozzle of the solidified material such as cement milk. The gist of the invention is to use a long one having a distance of about 1 to 3 m and to make the distance between the injection position of the ultra-high pressure water and the injection position of the solidified material such as cement milk longer. According to the present invention, since the injection nozzle of the ultra-high-pressure water and the injection nozzle of the solidified material such as cement milk are separated from each other in position, the effect of inducing and discharging the solidified material such as cement milk by the air lift is reduced. be able to. Hereinafter, embodiments of the present invention will be described in detail. 1 to 5 are longitudinal front views of respective steps showing one embodiment of the high-pressure jet injection mixing treatment method of the present invention. First, as shown in FIG. 1, a guide hole 17 is cut with a drilling rod 16 such as a boring machine. The holes are the same as in the first embodiment. This embodiment is almost the same as the conventional triple pipe method shown in FIGS.
Is a casing pipe 13 having a metal crown 11 and a stabilizer 12 at the tip by a boring machine 10 in FIG.
The guide hole 17 is constructed with this. A triple pipe built in the guide hole 17
Reference numeral 22 denotes an interval of about 1 to 3 m, whereas the triple pipe 8 in the conventional example has an interval of about 40 to 50 cm between the injection nozzle 23 of the ultra-high pressure water and the injection nozzle 24 of the solidified material such as cement milk. It was long. Subsequent steps are the same as those of the above-mentioned conventional example. Although not shown, a triple pipe swivel is installed at the upper end of the triple pipe 22, and compressed air 3 and ultra high pressure water Further, the hardening material 7 is injected from the injection nozzle 24 for the solidified material, and the triple tube 22 is pulled up while rotating. (See FIGS. 3 and 4.) As shown in FIG. 5, the triple pipe 22 is pulled out, and the column construction is completed. In this way, mixing the jet water and the cement milk can be prevented by increasing the distance between the jet injection position and the cement injection position. As described above, in the high-pressure jet injection mixing method of the present invention, the amount of wastewater is surely reduced by reducing the cement injection amount as a solidifying material, and as a result, wasteful This eliminates the need for sludge treatment and reduces waste of cement.
