Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dam structure having a water quality purification and virus disinfection system,

The present invention relates to a groundwater dam structure having a water purification and virus disinfection system and a construction method thereof. More particularly, the present invention relates to a groundwater dam structure having a water purification and virus disinfection system, And the groundwater is drained to the ground, and purification and virus sterilization are performed. Thus, it is possible to stably secure the raw water for drinking water used for various living water, and to prevent infectious diseases caused by various viruses and bacteria, By adopting a laminated water wall that can be installed without any excavation, it is possible to simplify the construction of the underground dam structure and reduce the labor cost and the installation cost compared with the conventional one. Therefore, the underground dam structure having water purification and virus disinfection system and its construction ≪ / RTI >

Due to climate change such as drought, water-scarce countries including Korea are continuously constructing dams to secure surface water, and securing and using groundwater is becoming very important.

In other words, when it rains, the flow rate is so fast that it can not easily penetrate into the ground. In order to secure living water and agricultural water, rock water is drilled to take water from the aquifer.

Since the rainwater storage facility is not installed in the book site, the rainwater is mostly flowed into the sea, and the rainwater storage facility requires a considerable structure at the time of construction. Therefore, a great construction cost is incurred. .

Therefore, in Korea, most of the water that people need to live up to now is purifying the water taken from the dam or the reservoir, or developing the rock groundwater as tap water. However, while the use of tap water is increasing day by day, there is not enough means to produce raw water of tap water, and it is expected that there will be a considerable water shortage in the future.

In developed countries, water is not sterilized by using chlorine, while Korea is sterilizing chlorine. Due to the risk of chlorine and unpleasant odor, it is disturbed by tap water, so tap water is not used as a negative water. The viruses or various bacteria are sprayed on wildlife or the virus introduced into the groundwater by animal bodies can cause serious diseases that can not be coped with chlorine disinfection. In terms of hygiene and national security, viral disinfection facilities are absolutely necessary.

On the other hand, the groundwater is stored in the permeable layer in the ground and eventually flows to the river. Efforts to secure the groundwater resource by storing the groundwater by blocking the flow of the groundwater flowing down to the river naturally have been continued. , A groundwater dam structure is being used as a means of such a method.

In order to secure a stable underground water supply, such an underground dam structure is provided with an artificial water wall in an aquifer through which groundwater flows, thereby raising the groundwater level and facilitating the water intake.

FIG. 1 is a schematic view showing a state in which the underground dam structure is installed in the ground.

However, in the conventional art as described above, after the water walls are installed in multiple stages, the groundwater is filtered and purified through the purification module. This is because only the action of purifying the water quality of groundwater is performed, Since the purification module having the filter member sandwiched between the filter members is installed in the state of being buried in the ground, when foreign substances are accumulated on the filter member, the groundwater flow This can lead to problems that are not smooth.

In addition, when such a problem occurs, there is a disadvantage that it is difficult to maintain and manage the underground dam once installed in the ground. Therefore, there is a problem that the utilization of the underground dam installed at a huge construction cost is reduced and economic loss may occur.

In addition, when the underground dam is installed in a multistage manner as in the above-described conventional technique, when the amount of surface water flowing from the ground surface during the summer heavy rainfall increases or the water level of the groundwater becomes higher than the height of the underground dam structure, However, even if the groundwater is overflowed, the groundwater level does not rapidly decrease, so that the groundwater level remains high for a long period of time, causing damages such as flood damage during rainfall or difficulty in survival of plants and living organisms It could be.
