Groundwater refers to water that fills or flows through gaps between underground strata and rocks. Groundwater deep wells usually excavate rock below the ground surface to allow groundwater in rock aquifers to reach groundwater pumps in groundwater wells. It has been installed and pumped groundwater. Recently, the groundwater used in this way is deteriorated due to the inflow of various pollutants. In particular, one of the reasons for accelerating the contamination of groundwater was the inflow of surface water or contaminants from the surface area into the groundwater well without any resistance through an unsealed upper protection hole. In the meantime, the present inventors have developed various technologies and methods that can completely seal the upper part of the groundwater wells, while improving the functions of the components of the groundwater wells, while at the same time, fundamentally blocking the influx of contaminants from the surface. The company is developing products and supplying them to customers.

Conventionally, the closed upper protective hole for the groundwater core has not been focused on the development of a coupling device that enables a leak-free coupling while connecting the groundwater, which is raised through a positive pipe, to the water supply pipe inside the cylindrical body that is coupled to the casing. . The reason for this development was a great reason to secure the proper function while occupying the small area of the use site as much as possible when developing groundwater and installing the facilities. However, such a device can be satisfied with the size, but it does not comply with the regulations to configure the flow meter and the collection valve for water quality inspection inside the upper protection hole prescribed by the groundwater law. There was a problem that the inconvenience and cost increase to install a protective manhole or to construct a cavity for pipe connection and flow meter installation. In addition, flowmeters, measuring instruments, sensors, automatic valves, and heat exchangers, which are essential for various facilities such as groundwater, are vulnerable to fine particles such as sand contained in groundwater, and a strainer capable of filtering these foreign substances is essential. There was no choice but to. In addition, in order to treat the water quality that is unsuitable for some applications within the standard value, it is true that there is no inconvenience due to the limited internal area, although a water treatment device must be installed. In such a situation, the groundwater method, which is inevitably installed in the groundwater well, also supplies power to the water level measuring pipe configured to investigate and observe the groundwater level inside the groundwater well and the underwater heart pump installed inside the groundwater well. It was to solve the problem that the power line connector installed in order to connect the water level control line connected to the water level sensor for the automatic operation of the submersible pump is located in the upper part of the sealing cover. Because these facilities are located on top of the airtight cover, there is a limit to the configuration of the necessary equipment due to the limitation of the top surface of the airtight cover.

Groundwater core well (3) is installed by inserting the grouting casing (7) through the weathered rock to a depth of 1m or less through the weathered rock while digging down the ground surface to the size of 50 ~ 350mm diameter. The groundwater law requires that the grouting order wall (not shown) be constructed so that its thickness is 5 cm or more out of the grouting casing (7). In addition, the groundwater law stipulates the installation of a flow meter 10 and a water intake valve (not shown) inside the upper protection hole. In the present invention, the strainer or water treatment while installing a sealing cover 20 to seal the groundwater heart to the upper part of the extension casing (5) coupled to the protective casing (8) made of synthetic resin and coupled to the grouting casing (7) The unit portion 30 constituted by the device or the valve configuration device has the necessary configuration requirements so that it can be installed inside the grouting casing 7 beyond the extension casing 5 or the extension casing 5. For this configuration, facilities that must be excluded from the internal section of the extension casing 5 or grouting casing 7 through which the unit part 30 passes are installed to measure the groundwater level inside the groundwater well as prescribed by the Groundwater Act. It is a water level measuring pipe 50 facility with an internal diameter of 25mm or more. Since the power wire 90 and the water level control line 91 are flat in shape and the diameter or thickness thereof is generally about 10 mm, there is no great difficulty in securing the necessary volume. Accordingly, in order to prevent the water level measuring tube 50 from interfering with the unit 30, the outer casing of the extension casing 5 or the grouting casing 7 may be inserted in the vertical direction beyond the width at which the water level measuring tube 50 can be inserted.

It may be understood. In addition, as shown in FIG. 4, the inlet pocket tube 51 extends to the upper end surface of the casing 5 and the casing flange 65, and the plug 52 is configured according to the shape of the sealing cover 20. It may be to fill the top of the sealing cover (20). In addition, the unit portion 30 may be configured to be coupled to the discharge port 33 while utilizing the strainer, and in this case, only the discharge port 33 may be formed on the upper surface of the airtight cover 20. It is possible to form a structure of a simple closed cover 20 will have an effect that can greatly reduce the cost required for the production of the product. On the other hand, the power wire 90 and the water level control line 91 is to be drawn out through the wire casing 92 installed through the extension casing 5 or the grouting casing (7).

The coupling of the extension casing 5 and the grouting casing 7 is to engage the welding flange 66 and the coupling flange 67 by using a bolt 80b and a nut (not shown) or by welding. The coupling of the extension casing 5 and the sealing cover 20 was to be coupled using a bolt (80a) and the sealing cover 20 was to penetrate the inside to couple the unit portion 30. Of course, by forming a connecting socket (not shown) or a flange (not shown) for coupling at the bottom of the airtight cover 20, and by combining the unit portion 30 therein, substantially extending the casing (5) or grouting casing (7). The unit unit 30 may be located in the interior. In general, in case of utilizing the strainer function, the unit part 30 is coupled to the upper part of the unit part cover 31 using a bolt 80c, and the discharge part 33 penetrates the inner and outer sides of the unit part 30 side. ) Was formed. The discharge port 30 may form a chamber 35 having an expansion pipe, and constitute a coupling part such as a flange for coupling the flow meter 10 or the piping accessory. The lower end of the unit part 30 has a positive pipe 4 ) In the process of reducing the diameter of the unit pipe 30 from the diameter of the pump pipe 4 to the diameter of the pump pipe 4 so as to form a coupling part composed of a flange or a connecting socket so that No leakage was made. An extension pipe 37 is installed in the center of the unit part 30, and a plurality of water holes 38 are formed on the extension pipe 37 so that the pumped ground water can be introduced into the unit part 30 without resistance. After the upper part of the extension pipe 37 was closed, a spring 34 was installed to cover the unit part cover 31 so that the extension pipe 37 could be firmly coupled inside the unit part 30.

A filter net 36 was formed inside the chamber 35 formed at the discharge port 33 so as to effectively filter sand and the like mixed in the pumped groundwater. The foreign substances such as sand collected and collected in the lower portion of the unit portion 30 inside the unit 30 are connected to the bottom so that the cleaning valve 70 can be opened and discharged through the cleaning tube 71 installed. In order to utilize the water treatment device in the unit unit 30, the water treatment material (not shown) is filled in the unit unit 30, and the water is passed through the groundwater so that the purified water can be made. In the case of using the unit unit 30 as a bilge configuration device, the inventors of the present invention registered in Utility Model Registration No. 20-0360999 (Application No. 20-2004-0016661) and the "improved structure of the sealed groundwater core cover device". In the process of constructing the structure of the valve component for connecting the pump pipe (4) and the water supply pipe (6) without leakage, the valve structure is complicated by always considering a device structure for a separate water level measuring tube (50).
