Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a structural diagram of a groundwater pollution prevention facility.

Referring to Figure 1, after excavation of the topsoil excavation for groundwater development is completed, install an outer casing and grouting to prevent contamination. The outer casing is installed to prevent the inflow of pollutants from the ground or underground around the groundwater and to protect the groundwater internal facilities. An empty pipe is installed from the surface to the topsoil, weathered rock and soft rock 1.0m. After installing the outer casing, grouting is performed on the space between the excavation hole and the outer casing.

After the installation of the outer casing is completed, grouting is performed on the space between the excavation wall and the outer casing to prevent contamination from the surface. The grouting method is based on the method given in the Groundwater Business Performance Guidelines (Ministry of Land, Transport and Maritime Affairs, 2006), and is sealed by injecting cement for dimension at least 50mm thick. Before injecting cement, clean the surrounding area by recirculating clean water from the bottom, and grouting material is mainly composed of cement and water, and sand, bentonite, hydrated lime and aggregate are used as additives. On the other hand, in the grouting injection to the filling space by using the injection pump so that no voids in the injection space is carried out until the injection cement flows back to the surface. After the grouting injection is complete, wait until the injected material is completely solid before performing the lower rock excavation.

The inner casing is commonly used as a well material, and is divided into a hole (hole) with a hole (groove) so that groundwater can flow from the aquifer section, and a non-gong tube installed to prevent water or foreign matter from entering the casing in a section other than the aquifer.

Submersible motor pump is a kind of centrifugal pump using centrifugal force. It is a device that pumps and motors integrally and draws water deep in the groundwater while submerged.

A water intake pipe is a pumping facility that raises the ground water sucked from the submersible motor pump.

The flowmeter is installed to check the amount of groundwater withdrawn and includes a device that can measure the flow rate such as a time meter.

The extraction device is installed past the flowmeter and used for sampling of water quality test. Generally, the tap is used.

The casing cover is installed on the outer casing to prevent the upper facility from falling into the ball, and serves to prevent the upper contaminants from entering the groundwater hole.

The cover of the closed upper protection hole should have a locking function with good watertightness and should be equipped with an air passage with an insect screen and a degree of protection against flooding of facilities. The above is a description of the devices basically used in the groundwater utilization facilities.

The following are detailed installation standards for groundwater pollution prevention facilities that install upper guards (Revised 2010.2.16.)

The upper protection hole should be made of materials that are corrosion-resistant and resistant to external impacts, such as concrete and synthetic resin, and should be installed so that no water can penetrate into the groundwater development and utilization facility. In addition, the upper guard should be installed on the surface of the ground in such a size that the groundwater development and utilization facilities can be protected and smoothly maintained. However, it may be installed below the surface if the mayor admits that even if it is installed under the surface of the terrain, there is no problem in preventing contamination of groundwater. In addition, the cover of the upper protection hole shall not be introduced with pollutant index water from the outside, and shall be installed with a material and structure to prevent damage.

The upper part of the lower surface protective wall (casing) shall be installed at least 30cm above the ground surface and should be covered to prevent external contaminants from entering. The casing cover is to be made of non-corrosive materials and air passages with screens are to be provided. In addition, the lower end of the casing is to be installed to a depth not less than 3m below the surface, and in the case of excavating the rock layer should be installed more than 1m below the rock (soft rock layer) line.

The grouting thickness on the outside of the casing shall be at least 5 cm and shall be filled with material from the bottom of the casing so that it does not leak under the casing.

Lastly, pumping facilities installed in groundwater development and utilization facilities should use materials that do not cause water pollution.

2 or 3, the present invention, the water intake pipe 100, the submersible motor pump 200, the casing, the well 300, the intake cover plate 400, the flow meter 500, the discharge pipe 600 In the sealed ground water pipe information container consisting of a water extraction device 700, the protective container 800, the protective container lid 810, the well is inserted in the inner direction along the through hole formed in the lower side of the protective container 800 ( It wraps around the outer wall of 300, and the upper portion is open and hollow cylindrical tube information arc 820, and the bending portion 900 to close contact so that foreign matter does not flow between the tube 300 and the tube information arc 820. The sealed groundwater pipe information container is characterized in that it comprises a.

Unlike the conventional flange type connection of the present invention, the well is inserted into and connected to the lower portion of the protective casing 800. In the case of a conventional flange connection method, the out casing is cut and the flange is welded to the upper protection hole, but the present invention inserts the well 300 into the pipe information container 800 and the well 300 and the pipe information arc part. If the 820 is in close contact with the banding 900 is completed.

In the case of the bending portion 900, a bending body provided by bending a plate-like member having a circular shape; A bracket provided on one side and the other side of the bending body to clamp the hose by reducing the diameter of the bending body; And a fastening structure fitted into one of the fastening holes formed in the bracket.

In addition, in close contact with the tube 300 and the tube arc arc 820 by using the bending portion 900, the inner surface of the tube arc arc 820, the packing fitting groove 821 formed along the inner peripheral surface and The packing fitting groove 821 is inserted and mounted to the packing 822 to closely contact the tube 300 and the tube arc arc 820, the packing 822 is composed of a urethane elastic material and a rubber material. As a result, the pipe well 300 and the pipe door 820 may be tightly contacted to block foreign matter that may be introduced from the outside.

And the protective casing 800 and the protective cap lid 810 is made of a synthetic resin to reduce the weight. The tube casing 800 was manufactured using a synthetic resin that is much lighter than conventional concrete or lightweight foamed concrete. Since the tube information container 800 is light, it is easy to install, and the tube information container cover 810 is formed on the tube information container 800, so that the water intake pipe located inside the tube information container 800 is formed. It is easy to maintain the 100, the submersible motor pump 200, the well 300, the water intake cover 400, the flow meter 500, the discharge tube 600, the water extraction device 700 and the like.

In addition, the intake pipe cover 400 may be coupled to the water well 300 and the water tightly coupled to protect the groundwater core wells from external contaminants. Such an effect is one of the reasons why the wells 300 of the groundwater core wells are all made of steel pipes or stainless steel pipes so that the strength thereof can sufficiently withstand an impact from the outside. Therefore, even if the protection vessel 800 made of a synthetic resin material is damaged due to a flood or the like, the ground is eroded, the soil is eroded, or flows down and collides with the rapids. The well 300 and the intake pipe cover 400 will be able to protect the groundwater heart well while preserving its shape.
