If groundwater with these advantages is properly developed, the water shortage can be significantly improved.

However, the upper protection hole for using groundwater has a problem that the lifespan of the well is shortened because the fine sand or fine sand of the weathered sedimentary layer fills the holes in the water collection pipe and clogs them as the period of use elapses after installation. There is a problem in that it is difficult to expect continuous high-quality water quality.

In order to solve such a problem, in the prior art, the inside of the groundwater was cleaned through an air purging operation.

Air surging injects fluid into the inner space of the groundwater to discharge various contaminants, and when the groundwater is used for a long time, it is transported by lime, and the grains are paired to create a sedimentation action to clear the clogged water veins.

However, the conventional air surging operation has a problem in that the working time is delayed according to the removal and reinstallation of the raising pipe because the operation is performed after removing the raised pipe connected to the underwater motor to the outside of the upper protective hole, and to discharge the raised pipe There is a problem in that the cost increases because heavy equipment such as cranes must be used. Also, a separate bracket (flange) for fixing the raised pipe in the groundwater serves as an obstacle in the process of moving the contaminants in the groundwater drilling hole to the upper side. There is a problem in that flow resistance is generated and the air surging efficiency is lowered.

Depending on the design conditions, the water level measuring tube 110 and the screw socket 130 may be provided in plurality so as to have different direct diameters from each other.

12, a plurality of water level measuring tubes 110 having different diameters may be provided, and a plurality of screw sockets 130 having different diameters may be provided.

For example, the water level measuring tube 110 is composed of a pair of different water level measuring tubes, each of which has a diameter of 32 mm and 25 mm, and the screw socket 130 is a different screw socket. It is composed of this pair, and the diameter of each screw socket may be 50mm and 32mm.

Accordingly, since the standard of the air supply hose 160 connected to the screw socket 130 having a different diameter is also different, high-pressure air is passed through the air supply hose 160 connected to the screw socket 130 having a diameter of 50 mm. By allowing a smaller amount of air to be injected when high-pressure air is injected through the air supply hose 160 connected to the screw socket 130 having a diameter of 32 mm than when injecting, the amount of supplied air can be easily increased make it adjustable.

This is to adjust the amount of high-pressure air injected into the air supply tank 100 by varying the standard of the air supply hose 160, and the process of performing air surging at the work site where the upper protection hole 10 is installed. It makes it easier and more convenient to control the amount of air injected in the That is, without the need to measure the amount of supplied air, it is possible to control the amount of injected air simply by selectively connecting the air supply hose 160 to the screw sockets 130 having different diameters, making the operation easier and more convenient. can make it happen.

At this time, the water level measuring tube 110 having different diameters may be provided with a separate cap (not shown in the drawing) to open and close the upper inlet.

This cap blocks some of the water level measurement tubes 110 among the plurality of water level measurement tubes 110, and opens only the remaining part so that high-pressure air flows through the water level measurement tube 110 with an open entrance to the groundwater drilling hole 20 ) to be injected.

For example, when high-pressure air is supplied through the screw socket 130 having a diameter of 50 mm, since the amount of supplied air is large, the water level with a diameter of 25 mm among the water level measuring tubes 110 having diameters of 32 mm and 25 mm By installing a cap on the measuring pipe 110 and blocking it, the high-pressure air supplied to the air supply tank 100 is injected into the groundwater drilling hole 20 only through the water level measuring pipe 110 having a diameter of 32 mm, and another For example, when high-pressure air is supplied through the screw socket 130 having a diameter of 32 mm, it is determined that the amount of supplied air is relatively small, and a cap is installed on the water level measuring pipe 110 having a diameter of 32 mm to block By doing so, the high-pressure air supplied to the air supply tank 100 can be injected into the groundwater drilling hole 20 only through the water level measuring tube 110 having a diameter of 25 mm.

This will be explained with reference to FIG. 13 , if you want to perform an air surging operation, remove the screw plug 140 fastened to the screw socket 130 , and connect the nipple 150 to the screw socket 130 and supply air After connecting the hose 160, when high-pressure air is injected into the air supply tank 100, the high-pressure air is transferred to the groundwater through the water level measuring tube 110 exposed to the inner space of the air supply tank 100. It is injected into the perforation hole 20 to perform an air surging operation, and various contaminants inside the perforation hole 20 are raised along the push-up pipe 40 by the high-pressure air injected into the perforation hole 20. After passing through the upper protection hole (10), it is discharged to the outside through the air surging outlet (200).

According to the design conditions, the air surging outlet 200 may be made in the form of a 'L'-shaped pipe as shown in the accompanying drawings, and while the air surging operation is in progress, the upper protection hole 10 is on the upper side. They may be combined and configured to work.

That is, the air surging outlet 200 may be configured to be detachable from the upper protection hole 10, and thus, when the air surging operation is not performed, it is separated from the upper protection hole 10, and, conversely, the air surging operation During this process, the upper protection hole 10 is coupled to the upper side so that the air and various contaminants injected into the groundwater drilling hole 20 are discharged through the air surging outlet 200 .

Furthermore, when the air surging outlet 200 is separated from the upper protection hole 10, a separate cover may be coupled to the through hole to which the air urging outlet 200 is coupled to be provided.
