Horizontal collection pipe 210 is installed horizontally on the floor in the lower bed.

The horizontal collection pipe 210 may be a wedge wire type stainless steel tube or a double wedge wire type stainless steel tube. Wedge wire type stainless steel pipe is made of stainless steel (STS, STS316, etc.) and can be used permanently. It is designed to meet the site conditions to withstand corrosion and earth pressure in the bed. Normally, collapse pressures should be maintained between 200 and 350 PSI and at least 4 metric tons of tensile strength. In addition, the opening rate of the horizontal collecting pipe 210 is 20% or more, the horizontal collecting pipe 210 should be able to maintain about 0.03m / sec.

The diameter of the stainless steel pipe can be installed from 100mm to 600mm and the wedge wire type stainless steel pipe has a structure in which foreign matter naturally escapes into the pipe due to the flow rate of water flowing into the pipe when fine substances such as sand are caught in the pipe. have

Since the length of the wedge wire type stainless steel pipe is a detachable construction, it can be installed by connecting several pipes having a length of 1m to 5m according to the site conditions. In addition, the size of the slot ST of the horizontal collecting pipe 210 is determined by the particle size of the aquifer and the filling force. When the size of the slot ST is increased, the output increases, but a lot of time is required until the inflow of sand during the pumping. It takes Slot size used should be within 1 ~ 4㎜.

In addition, the horizontal collection pipe 210 may be made of stainless steel or reinforced iron and other materials, or may be made of a high strength carbon steel pipe. The horizontal collection pipe 210 may be installed by directly drilling the insertion or horizontal excavation equipment after drilling the casing, or may be installed by being installed in the lower bed.

At least one horizontal pipe (PAL1, PAL2, PAL3) is spaced apart from the horizontal collecting pipe 210 by a predetermined distance surrounding the horizontal collecting pipe 210, is installed at a predetermined distance in the longitudinal direction of the horizontal collecting pipe 210 It is integrally connected with the horizontal collection pipe 210 by the support and provided with discharge holes 220 on the surface.

In FIG. 2, only three horizontal tubes PAL1, PAL2, and PAL3 are illustrated for convenience of description, but as can be seen from FIG. 3, the horizontal tubes PAL1 to PAL4 surround the horizontal collecting tube 210. At least one may be provided as a structure.

The support part may be a flange FLG surrounding the horizontal collection pipe 210. The structure in which the flange FLG acts as a support is shown in FIGS. At least one hole is formed in the flange FLG, and horizontal tubes PAL1 to PAL4 are inserted into the holes.

In addition, the support part may be at least one support pipe B for connecting and fixing the horizontal pipes PAL1 to PAL4 corresponding to the horizontal collection pipe 210. The structure in which the support pipe B acts as a support is shown in FIGS. 5 and 6. The support pipe B is fixed to the surface of the horizontal collecting pipe 210 and is formed extending radially from the surface of the horizontal collecting pipe 210 and the horizontal pipes PAL1 to PAL4 corresponding to the ends thereof are fixed. The support pipe B may be fixed to the horizontal collecting pipe 210 and the horizontal pipes PAL1 to PAL4 by welding. However, the fixing method of the support pipe B is not limited thereto.

In addition, the length of the support pipe B is adjustable. By adjusting the length freely, the positions of the horizontal tubes PAL1 to PAL4 can be adjusted.

7a and 7b is a view for explaining the structure of the maintenance water and indirect intake source securing system using the removable bed filter method according to an embodiment of the present invention.

A collecting well 410 is installed at one side of the horizontal collecting pipe 210 and the horizontal pipes PAL1 to PAL4, and can supply air or water to the horizontal pipes PAL1 to PAL4 inside the collecting well 410. A connector pipe (PP) is installed.

At the end of the connection pipe PP, a device (not shown) for injecting compressed air into the connection pipe PP or a device capable of cleaning the horizontal pipes PAL1 to PAL4 by injecting washing water into the connection pipe PP (not shown) May be connected.

When compressed air is injected into the horizontal pipes PAL1 to PAL4 through the connecting pipe PP, the compressed air is sprayed in all directions to remove the sludge or the film on the surface of the gravel accumulated in the upper layer. By supplying oxygen to soil microorganisms and saturating the bed layers in the bed with oxygen, iron and manganese can be oxidized to reduce iron and manganese concentrations in the bed filtered water and to remove organic matter.

Horizontal pipes (PAL1 ~ PAL4) is arranged integrally with the horizontal collection pipe 210 in a form surrounding the horizontal collection pipe 210, so that oxygen is supplied to the soil around the horizontal collection pipe 210, to remove the sludge Since it can function, the collection efficiency of the horizontal collection pipe 210 can also be improved.

In addition, by compressing and spraying water into the horizontal pipes PAL1 to PAL4, the micro-emission may be accumulated on the inside or the surface of the horizontal pipes PAL1 to PAL4 and prevent the smooth operation of the horizontal pipes PAL1 to PAL4. It can be washed, and can also remove the earth and sand that can be filled in the horizontal collection pipe (210).

As shown in FIG. 7B, the maintenance water and indirect intake source securing system using the submerged bed filtering method according to the embodiment of the present invention is horizontal to the excavated layer 430 on the bedrock layer after being excavated to a constant depth in the bed. Horizontal collection pipe 210 is formed horizontally with the pipes (PAL1 ~ PAL4) formed integrally. On one side of the horizontal collecting pipe 210 is a collecting well 410 is formed to the ground. Inside the sump 410, a connection pipe (PP) is connected to the horizontal pipes for transmitting compressed air or water.

Horizontal collecting pipe 210 forms a layer using fine sand, coarse sand, gravel, and the like. And to form a carrier layer 420 that can be fixed to the soil microorganisms in order to secure and activate the soil microorganisms. The carrier layer 420 may be formed of a ceramic carrier or steelmaking slag, and is formed in a structure in which microorganisms are easily attached and ventilated. When the carrier layer 420 is formed, the soil microorganisms present in the bed can be increased, and the iron and manganese concentrations in the bed filtered water can be increased by oxidizing iron and manganese by saturating oxygen in the soil bed and saturating the bed layers in the bed. Can be lowered and organic matter removed.
