Description

The rapid-set injection system by high-speed jet fluid

The present invention relates to a quick injection device using a high-speed fractionation body of civil engineering to improve the soft ground, and more particularly, by efficiently partitioning and spraying air and cement hardener and quickener through an injection rod inserted into the ground. The present invention relates to a rapid jetting device using a high-speed fractionation body for achieving ground improvement by ultra-high pressure injection.

In the conventional ground improvement apparatus, a predetermined nozzle is installed on an injection pipe that is inserted into the ground, rotated and drawn to achieve ground improvement with a high-pressure injection force.

However, in the conventional ground improvement device, since the spray direction is horizontal on the injection pipe inserted into the ground, the permeability to break the structure of the ground is not uniform, so the penetration range of the hardener is uneven, so that the cutting range is expanded. There is a problem in that it is difficult and the composition of the solidified body is unstable.

Also, in the ground improvement device which makes the inclined spray, the gap of the nozzles arranged on the vertical line is arranged so as to achieve a uniform injection state, so that the jamming of the rod occurs when the long depth is improved, and it has a significant influence on the accurate formation of the improved body. There is a problem that the slime is not easy to discharge.

In addition, since the direction of jetting from the bit is a downward vertical portion, there is a problem in that the drilling force is weak at the time of drilling, so that it is difficult to maintain the vertical degree.
