In addition, the perforated rod 10 used in the present invention, the perforated rod 10 to form an air cutting layer 16 for forming the air cutting layer on the lowermost outer peripheral surface to form the air cutting layer 50 when the ground is improved. It is also possible to use, and it is also possible to use the punching rod 10 in which the spraying nozzle for forming the air cutting layer 16 is not formed, whether the spraying nozzle for forming the air cutting layer 16 is formed. Irrespective of the case, if the earth and sand supply device 70 that can selectively supply all or a part of the new earth and sand is installed and configured, all will fall within the technical scope of the present invention.

Referring to the working embodiment using the system of the present invention as follows.

First, ground excavation improvement equipment, concrete hardening material production equipment, and auxiliary equipment are installed organically on the soft ground to be improved and strengthened.

When the ground improvement reinforcement system is constructed in this way, the drilling rod 10 equipped with the drilling bit 17 is drilled to a depth necessary to improve the ground 100 (punching process step).

When the ground excavation work is completed as described above, the high pressure cutting water is supplied to the water supply passage 12 to be injected through the water spray nozzle 13, and the high pressure air is supplied to the air supply passage 14. In the state where the air passage is formed around the water spray nozzle 13, the drilling rod 10 is slowly drawn out while rotating.

Then, the high pressure cutting water is supplied through the water supply passage 12 formed in the drilling rod 10 to be sprayed toward the side wall of the ground 100 and at the same time, the high pressure air supplied through the air supply passage 14 is sprayed with water. The cylindrical air is injected into the outside of the body of water sprayed from the nozzle 13 and at the same time as the strong air is injected into the side wall, the cutting efficiency of the body of water is increased, thereby rapidly and accurately cutting the side wall inside the ground 100 to enlarge the inner diameter.

On the other hand, the sand (SAND) component is separated into the first soil by separating the soil, the first soil by using the vibrating body (21), the soil to be removed during the operation such as sand tank (SAND TANK) 22 The remaining slurry (SLURRY) is secondarily filtered by the centrifuge (24a) through the slurry tank (SLURRY TANK) 24, the water contained therein is sent to the water tank (WATER TANK) 23 is sent to the water pump (30) To the cutting water by

The remaining residual ingredients are sent to the sand tank 22 and the first and second filtered sand ingredients are transferred to the screw conveyor 26 to the blender 25 while the moisture is properly removed. After mixing the cement hardener supplied from the cement hardener supply device 27 with a suitable strength to produce a mortar having a small moisture content, the mortar produced in this way is punched using a concrete hardener pressure pump 28 By supplying again to (10), water and cutting soil are recycled as well as an equal improvement body (ground improvement process step).

In this case, when the place for construction is lacking in the cutting soil, such as the beach shoreline, or when the use is inappropriate, or when it is desired to increase the strength, soil sand is supplied to the sand tank 22 to be selectively selected. It supplies the appropriate amount of external soil into the sand tank 22 by using a separate soil supply device 70 installed in conjunction with the sand tank 22 so that it can be supplied as

Then, the external soils supplied into the sand tank are transferred to the mixer 25 and mixed with the cement hardener supplied from the cement hardener supplying device 27 at a suitable strength to produce mortar having a low moisture content. Since the mortar is supplied to the perforated rod 10 again by the concrete hardener pressure pump 28, it is possible to selectively supply all new soil in the ground as needed or to mix and use it with the cut soil. By supplying a predetermined amount, it is possible to supplement the shortage of the cutting soil or to replace it with all new soil, and to increase the strength easily and quickly (soil supply process step).

Therefore, the excavation and stirring work is not only accurate, but the concrete hardening material 60 is homogeneous, so that the concrete hardening layer having much higher strength and density can be obtained.

On the other hand, if the water spray nozzle 13 is formed to be connected to the water supply pipe 12 on the outer wall of the punching rod to correspond to each other, as shown in Figure 4, the upper and lower water spray nozzle (13) Jetted water is blown against each other at a predetermined position to be cut and filled according to the purpose, if the water spray nozzle 13 is configured to face each other in the opposite direction, up and down, the water is sprayed to face each other while rock The joints are filled and cut at the same time as the joints are severed and weathered.

Therefore, by injecting and hardening the concrete hardener 60, it is possible to obtain a high quality concrete hardened layer having a diameter.

As described above, the present invention uses a ground improvement reinforcement system and apparatus which is specially configured to construct a punched rod, and when the ground reinforcement work is performed by using the ground improvement reinforcement system, the cutting of the ground is easy and a better state. To obtain an improved layer of

Unlike the concrete hardener that is initially injected, it recycles the cutting soil that is thrown during the ground excavation and improvement work to filter out the impurities and moisture contained in the first and second times, and to mix the remaining sand (SAND) component and cement hardener to reconstruct the mortar. By putting in, the requirement of concrete hardener can be significantly reduced, and it is basic to recycle water and cutting soil.

In addition, by installing and configuring a separate soil supply device connected to the sand tank to be supplied to the sand tank by receiving the soil from the outside,

When there is a lack of cutting soil, such as a beach shoreline, or when it is not suitable for use, or when it is necessary to increase the strength, the soil supply device is used to meet the shortage of cutting soil, the replacement amount with suitable soil, and the increase in strength required.

By supplying all the new soil or supplying a predetermined amount to be used in combination with the cut soil, it is possible to supply a certain amount so that even if the ground to be strengthened is placed in any condition, it is equally suitable for the purpose of improvement and is homogeneous and strong. It is a very innovative invention that can obtain an improved body.
