The present invention relates to a ground drilling method using a water hammer with the reuse function of high-pressure drill water, in particular, to drill the ground using a water hammer hitting the hammer by hydraulic pressure in the groundwork development, civil engineering and construction work At the same time, the ground drilling method using a water hammer with the reuse of high-pressure punched water to separate and reuse the slime and water through the filtration pump for slime generated during drilling (WH & MTR METHOD: WATER HAMMER AND MUDDY WATER TREATMENT RECYCLING METHOD) It is about.

In general, in order to drive a support pile or to build a pillar in the ground during groundwater development, civil engineering, and construction work, it is necessary to go through the process of forming a ground hole by drilling the ground.

Conventional ground (G) drilling as described above is a method using a general-purpose air hammer (Air hammer) and a method using a water hammer used under special environmental conditions.

First, the ground drilling using the air hammer universally used as the former is connected to the air hammer (6), the drilling bit (8) and the rod (5) to the ground (G) drilling machine (4) drilling equipment, high pressure compressor The high pressure air generated in the compressor 1 is connected to the rod 5 through the high pressure hose 3, and the high pressure air through the high pressure hose 3 moves the ram of the air hammer 6 up and down. It is a construction method that generates a blow energy, the drilling bit (8) receiving the blow energy is a universally implemented as a system for drilling the ground (G) to form a drill hole (H).

More specifically, Figure 1 is a development view showing the ground drilling using a conventional air hammer, Figure 2 is an exploded perspective view showing a conventional air hammer, Figure 3 is a ground using a conventional air hammer It is a construction sectional drawing which shows the state to perforate.

As shown in these figures, the ground (G) drilling using the conventional air hammer (6) is installed by the compressor (1) in parallel (1 to 4 units), the air compressed by the compressor (900CFM) , 350PSI: 25㎏ / ㎠), and stored in the air tank (2), and then transferred to the rod (5) of the drilling machine (4) through a high-pressure hose (3) connected to the air tank (2), The ram 7 of the air hammer 6 connected to the rod 5 moves up and down to transfer the striking energy to the excavation bit 8 to drill the ground G and drill the excavation bit 8. The rock fragments crushed by the air are scattered while being discharged to the ground with air.

Ground drilling using the conventional air hammer 6 as described above has the following problems.

First, the ground boring using the conventional air hammer adopts a method of hitting the air hammer 6 by using high pressure air in the construction of downtown, so that the surrounding environment is reduced due to the dust generated during the construction of the downtown Pollution, civil complaints are caused by the noise and vibration generated by the blow of the air hammer 6, there is a problem that the input ratio is high due to excessive energy input by driving the compressor (1) to compress the air with high pressure. .

Second, since the ground perforation using the conventional air hammer has to be treated as a waste separately from the slime and dust generated by the ground (G) perforation due to the increased awareness of the environment, there is a problem in that additional additional costs are generated.

Third, the ground boring using the conventional air hammer has a problem in that a double operation occurs because a surging operation is required separately for sludge treatment.

Fourth, the ground drilling using the conventional air hammer has a problem that the force transmission force is weak compared to the water because the medium is air.

Fifth, since the ground drilling using the conventional air hammer is a perforation using air, dust is generated according to the perforation, and when the groundwater is ejected during the perforation, there is a problem that a separate groundwater treatment process is required.

Sixth, the ground drilling using the conventional air hammer has a problem that only 75dB of noise generated by the compressor during ground drilling, the overall noise of more than 80dB.

Seventh, since the ground drilling using the conventional air hammer uses lubricating oil in the air hammer during the ground drilling, there is a problem that environmental pollution occurs in the drilling site of the ground.

The latter, the ground drilling using the water hammer is connected to the water hammer 14, the drilling bit 12 and the rod 16 to the drilling machine 10, which is the ground drilling equipment, the high pressure generated in the high pressure water pump 50 High pressure water through the high pressure hose 60 to move the ram of the water hammer (14) up and down to generate the impact energy, the drilling bit 12 received the impact energy drilled the ground to drill holes ( It is a system that forms H) and is carried out under special environmental conditions.

Ground drilling using the conventional water hammer as described above has the following problems.

First, the ground drilling using the conventional water hammer has a disadvantage that it can be installed only when the special environmental conditions are satisfied.

That is, since it is possible to work only in the area where the absolute amount of water (350ℓ / min = 21,000ℓ / hour) required to operate the water pump to drive the water hammer is possible, there is a disadvantage that a large water source must exist nearby. .

Second, since the ground drilling using the conventional water hammer consumes a considerable amount of water (21,000ℓ / hour), the energy consumption increases in proportion to the distance in the pumping process for supplying water even when working near the source. have.

Third, the ground drilling using the conventional water hammer discharges the used water out of the drilling hole or around the underground drilling hole at the same time as the drilling, so that surging work in the drilling hole is unnecessary, but a considerable amount of slime flows around the drilling hole. Therefore, not only the pollution of surrounding rivers and groundwater and surrounding landscapes are damaged, but also passers-by through the construction site is inconvenient, and there is a problem of being a target of civil complaints in neighboring residential areas.

Therefore, the present invention was devised to solve the problems as described above, by using the water hammer to hit the hammer by hydraulic pressure in the groundwater development, civil engineering and building construction, while drilling the ground and at the same time generated Since the slime is reused by separating the slime and water through the filtration pump, there is no noise and dust, and the slime is discharged together with the water, so it is unnecessary to fill the water in the drilling hole and clean the drilling hole. It separates the slime discharged together and reuses water, and the slime is dry, so it is environmentally harmless and provides a ground drilling method using water hammer with the reuse function of high pressure punched water suitable for urban construction.
