Description

Technical Field [0001] The present invention relates to a filter media accommodation unit, a groundwater purification unit, and a construction method,

The present invention provides a filter medium receiving device in a groundwater tank so as to facilitate the insertion and extraction of filter media used for groundwater purification, And a method of constructing the groundwater reservoir including the same.

Groundwater is widely used because it exists after the sea and glaciers in the water present on the earth.

In particular, groundwater development is often performed in areas with fewer rivers or lakes. Unlike surface water such as rivers or lakes exposed to the outside, such groundwater has the advantage of being stable to contamination.

In addition, groundwater can be utilized in situations where surface water can not be used due to climate change or weather changes.

 In Fig. 1, there is shown an example of a groundwater tank for pumping groundwater.

Referring to FIG. 1, the groundwater control system includes a water collecting tunnel formed by filling filter media, a pumping device for pumping groundwater, and a water quality treatment device for purifying pumped groundwater.

At this time, the filter material provided in the collecting tunnel filters various impurities contained in the ground water flowing from the outside, but filters various impurities, and has a disadvantage that clogging occurs due to adherence of foreign substances to the pores formed between the filter materials.

In order to overcome such disadvantages, when the pores of the filter media are closed and the phenomenon of pollution of the groundwater by external pollutants occurs, there is a method of constructing a new pipe after closing the constructed groundwater pumping well, The method of redevelopment of Kwanjung through cleaning is widely used.

However, there is a disadvantage that the cost of constructing new constructions and the method of redeveloping constructions are large.

In order to solve the problem of the conventional groundwater maintenance as described above, there is a need for a groundwater purification system capable of cleaning or replacing the filter media by extracting the filter media inserted into the channel.

Hereinafter, the present invention will be described in detail with reference to FIG. 2 to FIG. 6, with reference to FIG.

FIG. 2 shows a flow chart of the groundwater maintenance construction method.

Referring to FIG. 2, the groundwater refinement method starts with a tunnel installation step (S10) for inserting the tunnel 200 having the screen sections 211 and 221 formed in the excavated groundwater collection hole.

3, the present invention is an apparatus for regulating water stored in an aquifer, which is a stratum having a high permeability coefficient indicating a quantity of water passing through a certain unit area per unit time, And a groundwater collecting space 230 formed on the central axis of the canal 200 without being fixed to the groundwater retaining filter material receiving device. The groundwater collecting space 230 is provided on the center shaft of the canal 200, And a packer (300) for blocking groundwater flowing into the tank (300).

4, the conduit 200 includes a first groundwater inflow pipe 210 for preventing foreign matter from entering from the outside, and a second groundwater inflow pipe 210 extending from a lower inner surface of the first groundwater inflow pipe 210 to an upper end And a second groundwater inflow pipe (220) radially spaced apart from the inner circumferential surface of the first groundwater inflow pipe (210).

The first groundwater inflow pipe 210 and the second groundwater inflow pipe 220 are formed in a circumferential direction at a position where the aquifer is present in the screen sections 211 and 221 into which the external groundwater flows, And is inserted into the groundwater pumping space 230 formed in the axial direction inside the second groundwater inflow pipe 220 through the screen sections 211 and 221.

Therefore, the groundwater refilling agent receiving device is provided between the first groundwater inflow pipe 210 and the second groundwater inflow pipe 220, and is connected to the groundwater pumping space 230 through the screen sections 211 and 221 It is to maintain the inflowing groundwater.

The screen sections 211 and 221 include a plurality of first screen members 211-1 and 221-2 formed in the vertical direction of the groundwater inflow pipes 210 and 220, 211-2, 221-2 intersecting with the first screen members 211-1, 221-1, and each of the second screen members 211-2, 221-2 is composed of the groundwater inflow And has a structure inclined toward the inside of the groundwater inflow pipes 210 and 220 from the upper side to the lower side of the pipes 210 and 220.

In detail, the outer groundwater flows through the holes formed by intersecting the first screen members 211-1 and 221-1 and the second screen members 211-2 and 221-2, The second screen members 211-2 and 221-2 are moved from the upper side of the groundwater inflow pipes 210 and 220 to the lower side of the groundwater inflow pipes 210 and 220 in order to prevent the debris of the aquifer from flowing into the groundwater flowing in from the outside. And has a plate shape that tilts toward the inside of the groundwater inflow pipes 210 and 220.

Thereafter, a rail 160 is slidably moved between the first groundwater inflow pipe 210 and the second groundwater inflow pipe 220, and a coupling rod 2 in which the unit body 100A is laminated is inserted (S20) is performed.

5 and 6, the preparation for inserting S20 is performed by using the rail 160 and the coupling rod 2 to safely secure the groundwater conditioning filter media receiving device to the screen sections 211 and 221 It is the preparatory stage for sending down.

Various materials can be used for the filter medium 1 provided in the filter medium accommodating space 120, but soybean gravel and broken gravel Bid (glass, ceramics, activated carbon) are mainly used.

Therefore, the groundwater inflow hole 130 formed in the groundwater refilling filter medium receiving device should have a smaller hole than the filter material 1 in order to prevent the material used as the filter medium 1 from being discharged to the outside.

At this time, since the groundwater inflating material receiving apparatus is formed with a plurality of groundwater inflow holes 130 for smooth fluid flow, the rigidity of the groundwater inflow holes 130 may be reduced and the shape of the groundwater inflow material receiving unit 100 are separated into a plurality of unit pieces 100A arranged in the circumferential direction and then moved to the screen sections 211 and 221 by using the rails 160 and then joined by using the coupling rods 2, And the coupling rod 2 and the rail 160 are inserted into the screen sections 211 and 221.

Thereafter, a filter material receiving device assembling step S30 is performed in which a plurality of the unit pieces 100A are fitted to the coupling rods 2 along the rail 160 to form a filter material receiving device for groundwater conditioning.

In more detail, the groundwater refilling filter material receiving device is disposed between the first groundwater inflow pipe 210 and the second groundwater inflow pipe 220 to purify groundwater flowing into the groundwater pumping space 230 It plays a role.

Referring to FIG. 5, the groundwater refilling filter material receiving device provided at the position where the screen sections 211 and 221 are formed has a cylindrical body formed with a perforation 110 in the axial direction, And a plurality of groundwater inflow holes 130 are formed on an inner circumferential surface and an outer circumferential surface of the filter medium accommodating portion 100. The filter accommodating portion 100 has a structure .

That is, the groundwater introduced into the tunnels 200 through the first screen section 211 formed in the first groundwater inflow pipe 210 from the outside flows through the inflow hole 130 formed in the outer circumferential surface of the groundwater- And is discharged through the inflow hole 130 formed on the inner circumferential surface of the filter medium receiving device for purifying groundwater, And flows into the groundwater pumping space 230 through the second screen section 221 formed in the second groundwater inflow pipe 220.

Accordingly, the groundwater refilling filter media receiving device is inserted between the first groundwater inflow pipe 210 and the second groundwater inflow pipe 220 and fixed to the screen sections 211 and 221, and the screen section 211 And 221, respectively.

However, when the groundwater refilling filter media accommodating device is formed long, the inner circumferential surface of the first groundwater inflow pipe 210 and the outer circumferential surface of the second groundwater inflow pipe 220 during the insertion into the screen sections 211 and 221 Which causes difficulty in insertion.

FIG. 5 illustrates a method of inserting the filter media storage unit 100 into the screen sections 211 and 221 and stacking a plurality of the filter media storage units 100 to minimize the occurrence of the above-described problems.

5, a coupling hole 140 in which the coupling rod 2 is inserted is formed between the inner peripheral surface and the outer peripheral surface of the filter medium accommodating portion 100, And a rope (150) for fixing the groundwater storage media accommodation device to the screen sections (211, 221).

That is, when the rope 150 is inserted into the plurality of coupling holes 140 and the rope 150 is pulled, the central axes of the coupling holes 140 and the coupling rods 2 are aligned with each other, And the filter medium accommodating portion 100 is fitted to the rod 2 to form the filter medium accommodating device for groundwater conditioning.

At this time, the method of forming the filter medium for groundwater conditioning can be variously performed in addition to the above-described method.

6, the filter material receiving unit 100 is divided into a plurality of unit pieces 100A having an inner peripheral surface and an outer peripheral surface in an arc shape, and the unit pieces 100A are inserted into the screen sections 211 and 221, And the filter media storage unit 100 is formed by laminating the filter media storage unit 100 to form the filter media storage device for groundwater adjustment at the screen sections 211 and 221. [

At this time, when the unit body 100A is inserted into the screen sections 211 and 221 using only the rope 150, it is difficult to control the unit body 100A, so that it is difficult to combine the unit bodies 100A. It is recommended that the rails 160 to which the unit body 100 slides and move are inserted into the screen sections 211 and 221 at the ends of the arcs of the screen 100, respectively.

In detail, the unit body 100A is coupled to the coupling rod 2 by fitting the rope 150 into the coupling hole 140 formed in the unit body 100A, and the rails 160 ) To move to a predetermined position, thereby joining the plurality of unit pieces 100A to form the medium accommodating portion 100. [

At this time, it is sufficient that the medium accommodating part 100 formed by coupling the unit body 100A is inserted into the coupling rod 2 and coupled with each other, but it is possible to prevent the connection parts of the unit bodies 100A from being opened A structure in which a toroidal member having a structure corresponding to the lower end of the filter medium accommodating portion 100 is coupled to the lower end of the plurality of coupling rods 2 to support the respective unit bodies 100A, A structure in which the external skeleton surrounding the coupling portion of the unit body 100A is formed, and a structure in which the connection portions of the unit bodies 100A constituting the medium accommodating portion 100 coupled on the toroidal member are formed to be shifted from each other Therefore, it is not limited.

Further, the additional rope 150 is coupled to the lower end of the coupling rod 2, and it is possible to control the coupling rod 2 using the rope 150 outside the groundwater conditioning device.

Thereafter, a filtering material receiving device fixing step S40 for fixing the groundwater filtering filter material receiving device to the screen sections 211 and 221 using the rope 150 connected to the coupling rod 2 is performed.

At this time, it is sufficient that the rope 150 is fixed on the screen sections 211 and 221, but in order to facilitate extraction of the groundwater storage medium receiving apparatus to the outside of the groundwater pool, It is recommended to be fixed outside the device.

A packer 300, which is expanded from the upper side of the groundwater refilling filter media receiving device and closely contacts the inner circumferential surface of the first groundwater inflow pipe 210, the outer circumferential surface of the second groundwater inflow pipe 220, A packer installing step S50 is performed.

2, the groundwater refilling filter media receiving device is inserted between the first groundwater inflow pipe 210 and the second groundwater inflow pipe 220 and moves to the screen sections 211 and 221 Sectional area of the space formed between the first groundwater inflow pipe 210 and the second groundwater inflow pipe 220 in the circumferential direction.

Therefore, a clearance is formed between the inner circumferential surface of the first groundwater inflow pipe 210 and the outer circumferential surface of the second groundwater inflow pipe 220 and the groundwater refilling filter medium accommodating device, so that the groundwater introduced from the outside flows into the filter medium Can be inserted into the groundwater pumping space (230) without being purified in the groundwater treatment plant (1).

In order to solve the above-mentioned problem, the packer 300 for blocking the flow of groundwater at the top of the filter material receiving apparatus for groundwater maintenance is installed.

At this time, the packer 300 may include various types of packers such as an air packer that expands at the upper end of the groundwater-retaining filter material receiving device, an expansion packer that expands by absorbing moisture to block the flow of groundwater flowing through the upper end of the groundwater- It is not possible.

In order to block the flow of the groundwater flowing into the groundwater collecting unit 230 through the lower end of the groundwater retaining filter medium receiving apparatus, the groundwater tank is moved to the lower side of the screen sections 211 and 221, The first groundwater inflow pipe 210 and the second groundwater inflow pipe 220 are formed in a tapered structure so that the distance between the inner circumferential surface of the inflow pipe 210 and the outer circumferential surface of the second groundwater inflow pipe 220 becomes narrow, 2 groundwater inflow pipe 220 may be in close contact with each other.
