In addition, inside the encasing (2), a water level measuring tube (6) capable of monitoring the level of the groundwater to a certain depth is connected to the cardiac cap (14).

In the past, the groundwater core cover was made open to the outside so that the outside polluted atmosphere could flow into the groundwater well without filtration, and especially when the flood occurred, the contaminated surface water would flow into the groundwater well without any obstacle. In addition, there were cases where the burred considers the inside of this humid groundwater well to be a good habitat, and groundwater was contaminated with general germs and E. coli, and the groundwater well could be easily infested with insects.

Therefore, the present inventors have invented or devised a method and apparatus that can be completely isolated and managed from the outside into the groundwater core well through 'French for groundwater vacuum pumping device' and 'groundwater pumping device'.

However, when the airtight core cover is installed on the existing groundwater well, it is difficult to cut and refit the beast pipe because the height of the existing pumping pipe is not exactly correct. Especially, the sealing of the power cable, the water level detection line, and the water level measurement pipe There was an inconvenience inevitably involve a complex sealing device.

The present invention was devised to solve the above-mentioned problems of the prior art, and constitutes a cover that can completely block the groundwater well inside and outside, and can be applied to groundwater wells in use as well as new wells. The purpose of the present invention is to provide a groundwater core cover of a structure that can adjust the height.
