Description

The protective apparatus for pipe equipment that supplying subterranean water}

The present invention relates to a well protection device which is installed in a form buried underground to prevent damage to the wells constructed for the intake of groundwater.

Groundwater, which is cleaner than river or river water, is used for the purpose of living water, agricultural water, and industrial water.

In order to collect and use groundwater, it is essential to construct a well that connects the groundwater to the groundwater source with groundwater.

Previously, small house-shaped jangoks were installed to prevent damage to the wells to collect groundwater.

However, these jangok had a problem that takes a lot of installation cost and occupy a lot of the installation area.

In addition, there was a disadvantage that can not expect the effect of preventing the contamination of the groundwater source.

In addition, there was a problem that freezing accidents occur frequently in the groundwater supply line in Jangok during winter.

In order to solve such a problem, a tube cover device (Korean Patent Registration No. 10-0699909, Korean Patent Registration No. 10-0640143, etc.), which consists of a protective cover and a protective case and allows most of the protective case to be embedded, has been devised.

When the pump pipe is installed as described above, the pump or replace the water motor or repair and replace the submerged motor occurs. For this purpose, the pump should be removed from the well.

In order to facilitate the maintenance as described above, a technology for easily separating and combining the portion connecting the pumping pipe and the groundwater supply pipe (Korean Patent Application No. 10-2007-0001942, Korean Utility Model Application No. 20- 2005-0013783, Korean Patent Application No. 10-2006-0057226, Korean Patent Application No. 10-2006-0057226, and the like.

However, all of the prior art as described above are technologies that are applied to a small well protection device but are not applicable or inappropriate to a large well protection device having a large size of facility installation space.

That is, since the pumping pipe is connected to the pumping pipe and the ground water supply pipe, the two points are connected. In the case of a large well protection device, the distance between the connecting points is quite far.

By the way, the prior art is to connect the two points by the force acting at one point, suggesting only the configuration suitable for the short distance between the connection point, difficult to apply to large well protection device with long connection point, diarrhea Even if it was applied, not only was it leaking, but the task was very difficult.

In addition, the prior art has a problem that a significant inconvenience occurs in the operation such that the ground water supply pipe is inserted into the inner space of the protective case to be connected to the pumping pipe.

In addition, Korean Patent Application No. 10-2007-0001942 (Anti-waterproof, waterproof device for watertightness of the wells) is provided with a positive pressure connecting pipe by a cover to connect the pumping pipe and the groundwater supply pipe to separate and connect the pumping pipe. Techniques to facilitate this are presented.

However, in the above technology, the pump is connected to the "∩" type, etc., the groundwater is returned to the bent portion, the water pressure is weakened, and the load on the submerged motor has been a problem.

In addition, when the submersible motor is operated while the cover is open, groundwater leakage is largely generated, which causes a problem that the working environment becomes messy.

Korean Utility Model Application No. 20-2005-0013783 (closed top pollution protection device of the lower surface protection casing) connects the "a" type pumping pipe to the pumping pipe and the groundwater void pipe, and is located on the upper part of the protective case. When the handle is rotated, a rocker connected to the handle is moved to be connected, thereby providing a technology for facilitating separation and engagement of the pump.

However, the above technique has a problem that the groundwater leakage occurs at a certain point as the tightening force of the rocker is gradually released by the impact generated when the groundwater is repeatedly supplied and stopped.

In addition, since the size of the locker structure is large, the case of the protective case is small, there was also a disadvantage.

Korean Patent Application No. 10-2006-0057226 (Decision Facility Protection Device) discloses a technique of connecting a positive connector of a type "a" using a clamp but using a clamp to fix it.

However, the above technique has a problem that the clamping point is located at a very deep position at the upper end of the protective case, and the workability is not good because the space inside the protective case is narrow.

In addition, the connection between the pumping pipe and the groundwater supply pipe is made directly by the clamp, but the connection between the pumping pipe and the pumping pipe is to cause the pumping pipe to be pressurized in the direction of the pumping pipe so that leakage occurs due to strong water pressure. There was this.

On the other hand, the conventional pipe information arc device is only to connect the water supply pipe and the ground water supply pipe inside the protective case was not intended to prevent groundwater contamination.

Therefore, when the protective cover is removed, the interior space of the well is opened through the facility installation space of the protective case (the space between the outer pipe 3a and the pumping pipe 1 located at the outermost side of the well 3). In this case, the external pipe 3a is made of metal and the inner pipe 3b is positioned at the outermost side, and the inner pipe 3b is located at the inner side thereof. Most of them are able to insert the pump tube (1) inside the 3b)

In particular, in the case of opening the protective cover and repairing the internal facilities, inflow of soil or pollutants generated during the work was frequently generated.

In addition, there are many cases in which the protective case is provided with a hole for ventilation, in which a worm enters the groundwater source through the well.

In addition, there is a lot of precipitation during the rainy season, so the cover may be immersed in rainwater.In such a situation, when rainwater flows into the inside of the protective case, the rainwater flows directly into the groundwater source through the well and leads to contamination of the groundwater source. There was a problem.

The present invention is to solve the problems as described above, more specifically using a pumping pipe connecting the pumping pipe and the groundwater supply pipe connecting operation and the separation of the pumping pipe is easy to work between the connection points The objective of the present invention is to provide a well-protected well-protected well, even if it is applied to large well-protected wells.

In addition, the purpose is to facilitate the connection between the protective case and the groundwater supply pipe.

In addition, there is also an object to provide a well protection device that can be prevented from entering contaminants into the groundwater source even if applied to the well having an outer pipe and the inner pipe.

The well protection device of the present invention, the facility installation space is formed, the pumping pipe insertion hole is formed communicating with the pumping pipe, the protective case is formed on the outside of the pumping pipe insertion opening;

A protective cover for blocking or opening the facility installation space of the protective case;

A pumping tube fixed body fixed to an outer side of the pumping pipe to prevent the pumping pipe from descending along the pipe when the pumping pipe is inserted into the pipe;

Is installed on the side of the protective case, the flow path connecting pipe is connected to the ground water supply pipe;

A pumping connector connected to one of the pumping pipes and the other of the pumping pipes;

Pipe connecting means for connecting the flow path connector and the positive connector;

It is fixed to the pumping pipe rotatable, and the connection state maintaining means having a stopping plate to be connected to the pumping pipe is in close contact with the pumping pipe is connected to the holding projection to maintain the connection between the pumping pipe and the pumping pipe; It is configured by.

In the preferred structure as described above, there is no connection state maintaining means, but the pumping pipe is connected to the pumping pipe, and the upper end of the pumping pipe is inserted deeply into the pumping pipe, and occurs between the side of the pumping pipe and the inside of the pumping pipe. It is also possible to allow the gap to be blocked by the packing.

In other words, in the present invention, the pumping pipe and the groundwater supply pipe are connected by the pumping pipe, but the connection point of the pumping pipe and the pumping pipe by the connection state maintaining means is easy to operate in the state in which the connection is made by the pipe connecting means. Maintaining this tight connection keeps the leak tight even when applied to large well protection devices.

In another form, the pumping pipe and groundwater supply pipe are connected by the pumping pipe, but when the connection is made by the pipe connecting means, a leak is generated by preventing a gap between the pumping pipe and the side of the pumping pipe. It is to maintain the firmness.

In addition, the pipe connecting means or the connection state maintaining means of the present invention is to make the structure easy to work when trying to separate the pumping pipe.

In addition, by connecting the groundwater supply pipe from the outside of the protective case without the need to flow into the inside of the protective case to facilitate the installation work.

In the apparatus of the present invention, the pumping pipe and the groundwater supply pipe are connected by the pumping pipe, and the pumping pipe and the pumping pipe are connected by the connection state maintaining means which is easy to operate in the state where the pumping pipe is connected by the pipe connecting means. The connection point is designed to maintain a solid connection, so that even in the case of large well protection devices, it is possible to maintain a solid connection without leakage.

In the structure that does not have the connection state maintaining means as described above, the pumping pipe is connected in the state of being inserted into the pumping pipe and there is no gap between the pumping pipe and the side of the pumping pipe, and the pumping pipe is deformed by water pressure. No phenomenon occurs and no leakage occurs.

In addition, the pipe connecting means or the connection state maintaining means is easy to operate the separation of the pumping pipe is easy.

In particular, when the rotating rod located on the upper portion of the protective case is connected to the pumping pipe is connected to the pumping pipe and ground water supply pipe, when rotating the rotating rod in the opposite direction is released so that the coupling force is released to separate the pumping pipe It is very easy to separate and join the pump.

In addition, in the configuration provided with the loosening prevention means for holding the rotating rod in the impact generated when the supply and stop of the ground water is not weakening the coupling force for the connection of the pump pipe, thereby causing no leakage.

In the configuration in which the groundwater supply pipe is connected to the outside of the protective case in the present invention, it is easy to install the groundwater supply pipe as well as to install the well protection device of the present invention.

In addition, if the upper part of the well is blocked by the protective case and the pump pipe fixing body, and the water level measuring tube is formed to easily measure the water level of the groundwater source, even if foreign matter or rainwater enters the facility installation space of the protective case, Since it does not flow into the groundwater source, contamination of the groundwater source is prevented.

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

1 is a cross-sectional view of a state in which the apparatus of the present invention is installed.

The present invention corresponds to a device for protecting a well, and has a protective case 10, a protective cover 20, a positive connection pipe 30 as in the known art.

The protective case 10 is a facility installation space 11 in which various structures can be located is formed and is buried underground in a state where the lower part is connected to the well.

In addition, the protective cover 20 is to be separated and coupled to the protective case 10 to block or open the facility installation space (11).

In addition, the pumping pipe 30 is connected to the pumping pipe (1) and the ground water supply pipe (2) so that the ground water raised on the pump pipe (1) by the underwater motor or the like to be supplied through the ground water supply pipe (2) It is.

However, due to the necessity of replacing and repairing the submersible pump installed at the lower end of the pumping pipe (1) or repairing the pumping pipe (1) with the well protection device installed, it is necessary to separate the pumping pipe (1) from the well. .

Since this situation occurs, the pumping connection pipe 30 needs to be easily coupled and separated for connection (when a meter or sand remover is installed in the pumping connection pipe 30, a meter or sand remover, etc.). This is also necessary for easy repair and replacement.)

In the past, techniques for ease of separation and coupling have been proposed, but techniques have been accompanied by various problems such as weakening of the binding force and leakage of water or weakening of water pressure as time passes.

Above all, if the distance between the connection point of the pumping pipe 30 (the point connected to the pumping pipe 1 and the point connected to the ground water supply pipe (2)) there was a problem that the water leakage occurs in a strong water pressure.

The present invention proposes a structure that can be easily separated and combined, as well as maintaining a firm bonding force for a long time to prevent leakage.

Preferred structure is the structure as shown in FIG.

In the well protection device of FIG. 1, a facility installation space 11 is formed, and a pumping pipe inserting hole 12 communicating with the pumping pipe 1 is formed, and a catching protrusion 19a is disposed outside the pumping pipe inserting hole 12. ) Is provided with a protective case (10).

In addition, the protective cover 20 is provided to block or open the facility installation space 11 of the protective case 10.

In addition, the pumping pump fixed to the outside of the pumping pipe (1) is caught on the outside of the pumping pipe insertion opening 12 when the pumping pipe (1) is put into the well, and prevents the pumping pipe (1) from descending along the well (3) The tubular fixation body 40 is provided.

Moreover, the flow path connecting pipe 80 which is provided in the side surface of the protective case 10 and is connected to the piping 2 for groundwater supply is provided.

In addition, one side is connected to the pumping pipe (1) and the other is provided with a pumping connecting pipe (30) connected to the flow path connecting pipe (80).

In addition, there is provided a pipe connecting means 90 for connecting the flow path connecting pipe 80 and the pumping connection pipe 30.

In addition, it is fixed so as to be rotatable to the pumping pipe 30, the pumping pipe 30 is caught in the engaging projection (19a) in close contact with the pumping pipe (1) pumping connecting pipe 30 and pumping pipe (1) is provided with a connection state holding means (120) having a locking plate (121) to maintain the connection state.

The structure as described above is made of the connection pipe (1) by the pipe connecting means (90) while the positive connection pipe 30 is coupled to the flow path connecting pipe (80), the connection of the positive pipe and the positive connection pipe (30) The point is a structure that can be connected more firmly by a separate connection state maintaining means 120 and can not be separated.

In general, there is a problem that the workability is not good because the connection point of the pumping pipe 30 and the flow path connector 80 is far from the upper end of the protective case 10.

The structure of FIG. 1 is a pumping pipe 30 in a state in which the pumping pipe 1 and the flow path connecting pipe 80 (connected with the groundwater supply pipe 2) are connected by a pipe connecting means 90. Press more firmly by pressing the pumping pipe 30 is in close contact with the pumping pipe 1 so that the locking plate 121 of the connection state maintaining means 120 can not be caught by the locking projection 19a. To maintain a solid connection. (The locking plate 121 is moved from the upper portion to the lower portion of the locking protrusion 19a through a portion not facing the locking protrusion 19a, and then rotated to be caught at the lower portion of the locking protrusion 19a, thereby catching the locking protrusion 19a. Cannot be moved upwards)

In FIG. 1, a locking protrusion 19a is formed in the protruding pipe 19 formed on the outside of the pump pipe insertion hole 12, but the stiffening protrusion 19a may be formed on an inner wall of the facility installation space 11. It may be implemented in the form.

Pipe connecting means 90 for connecting the flow path connecting pipe 80 and the pumping connection pipe 30 can be implemented in various forms already known.

In FIG. 1, the positive connection pipe 30 is bent so that one side faces downward and the other side faces.

In addition, the tubular connecting means 90 is provided, but the tubular connecting means 90 has a rotating rod 91 which is spirally coupled to the protective case 10 and is rotated before and after the rotation, and the rotating rod 91 is moved forward. As the reverse or backward, one end of the positive connector 30 is moved in the direction of the flow path connector 80 and the other end of the positive connector 30 is moved in the direction of the pump tube (1) to the flow path connector ( 80 and an inclined surface 92 to be in close contact with the pump 1, respectively. (When the rotary rod 91 is advanced and pushes the positive connection pipe 30, the positive connection pipe 30 moves on the inclined surface, and the positive connection pipe 30 is coupled to the flow path connection pipe 80 and the positive water pipe.)

This configuration is not only easy to selectively remove and combine the pumping connection pipe 30, but also minimizes the pressure drop of the groundwater supplied by the submersible pump.

That is, in the related art, in order to facilitate separation and coupling of the amniotic fluid connection pipe 30, the amniotic fluid connection pipe 30 was often used in a "∩" shape.

However, such a pumping pipe has a problem of reducing the water pressure of the ground water supplied.

Of course, the prior art also has a structure in which the positive connection pipe 30 is bent so that one side is facing downward and the other side is directed toward the side.

In addition, there is also shown a structure that facilitates the separation, coupling of the positive connection pipe 30 by the inclined surface.

However, in the prior art, such a positive connection tube 30 is separated and coupled by self weight, or by being separated and combined by a complex clamp, so that a rigid coupling is not achieved or a significant inconvenience in separating and joining operations. There was a following issue.

However, as described above, the structure of the pipe connecting means 90 using the spirally coupled rotary bar 91 is easy to separate and couple the positive connection pipe 30, and a relatively solid coupling is achieved.

The configuration in which the inclined surface in the pipe connection means 90 as described above acts for separation and coupling of the positive connection pipe 30 may be applied in a modified manner as in the prior art.

However, as shown in FIG. 1, the first coupling plate 93, the second coupling plate 94, the support body 95, and the pressing body 96 may be implemented in the form of a rigid coupling, which is convenient and preferable. .

In the first coupling plate 93 of FIG. 1, a hole is formed in the center portion, and an inclined surface is formed toward the outside near the edge, and is integrated with the flow path connecting pipe 80.

In addition, the second coupling plate 94 has a hole formed in the center portion, and an inclined surface is formed toward the outside near the edge thereof, and is integrated with the positive connecting pipe 30.

In addition, the support body 95 has a shape corresponding to the inclined surface formed in the lower portion of the second coupling plate 94 and has an inclined surface in which the inclined surface formed in the lower portion of the second coupling plate 94 is in contact with each other.

In addition, the pressing body 96 has a shape corresponding to the inclined surface formed on the upper portion of the second coupling plate 94 and has an inclined surface in contact with the inclined surface of the second coupling plate 94 when moved upwardly or downwardly. have.

Therefore, the positive connection pipe 30 is placed in a position for coupling, and the rotary rod 91 is rotated while the pressing body 96 is moved while pressing the second coupling plate 94, and the coupling is made while naturally taking the correct position.

However, if only the spirally coupled rotary rods 91 are coupled to the positive connection pipe 30 to the flow path connecting pipe 80 and the positive water pipe, a weakening force occurs over time, resulting in groundwater leakage. Leads to problems.

This is because the groundwater is repeatedly supplied and stopped, and a fine shock (vibration) is generated in the pumping pipe 30 by the water pressure of the groundwater, and this vibration is increased as the coupling force is weakened.

Therefore, as shown in Figure 1, by the rotation of the rotating rod 91, the positive connecting pipe 30 is connected to the flow path connecting pipe 80 and the pumping pipe (1) that the rotating rod 91 is released by the impact (reverse rotation It is necessary to further provide the release preventing means (97) to prevent the phenomenon).

The anti-loosening means 97 may be implemented in various forms to hold the rotating rod 91 so that shaking does not occur in the rotating rod 91 even when an impact caused by the supply and stop of the ground water is generated in the positive connection pipe 30.

However, as shown in Figure 1 it is preferable to implement in the form having a release preventing nut (97a) that is tightened to be in close contact with the fixed object in the state of being coupled to the rotating rod (91).

In order to achieve the object of the present invention may be implemented in the form as shown in FIG.

In the well protection device of Figure 2, the facility installation space (11) is formed, the protective casing is formed in the basement in the state connected to the bottom of the well, the pumping pipe insertion hole (12) formed in communication with the pumping pipe (1) 10) is provided.

In addition, by being spaced apart and fixed at the upper end of the pumping pipe (1), when the pumping pipe is put into the well, the pumping pipe (1) is prevented from falling down along the well, and the pumping pipe (1) A pumping pipe fixing body 40 is provided so that the upper end of the protrusion protrudes into the facility installation space 11.

Moreover, the flow path connecting pipe 80 which is provided in the side surface of the protective case 10, and is connected to the ground water supply piping 2 from the outer side of the protective case 10 is provided.

In addition, it is connected to the pump pipe (1) toward the lower side and the other side is bent to face the side connected to the flow path connecting pipe (80), the pumped water is made of a rigid material so that the bent state is not deformed by water pressure The connection pipe 30 is provided.

In addition, the packing 16 is provided to block the gap generated between the side of the pumping pipe 1 and the inner side of the pumping pipe 30 in a state where the pumping pipe is inserted into the pumping pipe 30.

That is, Figure 2 is a structure that does not have a connection state maintaining means 120 as in FIG. 1, but the pumping pipe (1) is connected in a state inserted deeply into the pumping pipe (30) and pumping pipe (1) and pumping connection The packing 32 is installed between the side surfaces of the pipe 30 so that no gap is generated, and the phenomenon in which the positive connection pipe 30 is deformed by water pressure does not occur.

In particular, even if a portion of the pumping connection pipe 30 connected to the pumping pipe 1 rises upward due to water pressure, the gap is blocked by the packing 16 located on the side of the pumping pipe.

From the standpoint of leakage prevention, the structure as shown in FIG. 2 has a lower effect than the structure as shown in FIG. 1 but shows a very improved effect compared with the prior art.

Of course, in the case of FIG. 1, even if the distance between the connection points in the positive connection pipe 30 is very long, excellent leakage prevention effect can be expected, but in the case of FIG. 2, there is a limit in the distance between the applicable connection points.

In the structure as shown in Figure 2, the positive connection pipe 30 should not be a deformation such as bending caused by the water pressure (pressure generated when the ground water is supplied), the positive connection pipe 30 should be implemented with a hard material such as metal do.

In the configuration as shown in FIG. 2, it is preferable to further include a rib 31 connecting the vicinity connected to the groundwater supply pipe 2 and the vicinity connected to the pumping pipe.

This is to ensure that the force applied to connect the positive connector 30 is smoothly transmitted to the two connection points at the same time so that deformation of the positive connector 30 does not occur.

On the other hand, the conventional well protection device was all to block the space inside the protective case 10 to prevent contamination of the groundwater source.

In practice, there is considerable difficulty in preventing the contamination of groundwater sources with only the above configuration.

In order to prevent contamination of the groundwater source, even if foreign matter such as soil or rainwater flows into the facility installation space 11 of the protective case 10, it should be prevented from entering the inside of the well.

To this end, the protective case 10 of the present invention is preferably configured to block the upper part of the well when connected to the well as shown in FIG.

In addition, the pumping pipe fixing body 40 is fixed to the outside of the pumping pipe (1) to be injected into the well and integrated with the pumping pipe (1), the pumping pipe is caught on the outside of the pumping tube insertion opening (12) of the protective case 10 It is preferable to prevent the pumping pipe insertion opening 12 from being blocked while descending along the well. (The pumping pipe insertion opening 12 is preferably formed as small as possible.)

In other words, the upper portion of the well (3) by the protective case 10 is blocked and inevitably formed in the pumping tube insertion hole 12 is to be blocked by the pumping tube fixing body (40).

Unlike FIG. 1, it may be configured as shown in FIG. 7.

FIG. 7 prevents the pumping pipe 1 from being caught by the pipe fitting flange 70 and prevents the pumping pipe 1 from descending along the pipe well 30, and blocks the pumping pipe inlet 72 of the pipe fitting flange 70. It is a structure.

That is, the pumping pipe fixing body 40 is not caught by the protective case 10 but is caught in the pipe fitting coupling flange 70 and prevents the pumping pipe 1 from descending along the well while inevitably pumping the pipe fitting coupling flange 70 formed therein. By blocking the tube insertion hole 72 is to block the top of the well.

In FIG. 1, a water pipe insertion hole 12 and a water level measuring hole 14 are formed so that the facility installation space 11 and the pipe can communicate with each other, but the water level measuring hole 14 is formed outside the pumping pipe insertion hole 12. It is.

The reason for forming the water level measuring instrument 14 is to send the water level measuring instrument to the groundwater source to measure the level of the groundwater source or to send various sensors to the lower part of the well to perform various measurement or inspection work.

Such a water level measuring instrument 14 is preferably formed on the outside of the water pump insertion hole 12, which needs to lift the water pump for repair of the underwater motor or pump, in which case the water level measuring instrument 14 This is because the work is convenient if the work is not affected.

It is preferable to form the wire mounting device 15 in the pump pipe fixing body 40. The reason is that the power supply line must be connected to operate the submersible pump located at the bottom of the pump pipe, and the pump pipe (1) This is because the power supply line should not be obstructed when lifting to facilitate the operation.

Foreign material or rainwater may be introduced through the open wire installation port 15 and the water level measurement port 14.

For this reason, in FIG. 1, the wire installation pipe 50 and the water level measurement tube 60 extending from the entrance of the wire installation port 15 and the water level measurement port 14 to the upper portion of the facility installation space 11 are provided.

One side of the wire installation pipe 50 is connected to the wire installation port 15 and the other is a long form extending to the upper portion of the protective case (10).

In addition, one of the water level measuring tube 60 is connected to the water level measuring sphere 14 and the other is a form extending long to the upper portion of the protective case (10).

Since the wire installation port 15 and the water level measuring tube 60 as described above can be formed small and extend upward, even if foreign matter falls to the facility installation port during the installation or repair work, the wire installation pipe 50 or the water level. The probability of flowing into the groundwater source via the measuring pipe 60 is very low.

In addition, even if a large amount of rainwater flows into the facility installation space 11, the entrance of the wire installation port 15 and the water level measurement pipe 60 is located higher than the bottom of the facility installation space 11 so that rainwater does not flow.

The upper part of the water level measuring tube 60, which allows the water level measuring instrument 60 to be introduced into the lower part of the well in the facility installation space 11 even when the pumping pipe fixing body 40 blocks the pumping pipe insertion holes 12 and 72. It is desirable to be located higher than the center of the installation space 11 of the facility.

In addition, the water level measuring tube 60 is preferably as close as possible to the inner wall forming the facility installation space (11).

This is because there is a need to prevent the water level measuring tube 60 protruding from placing various facilities or wires in the installation space 11.

In particular, in the configuration where the water level measuring tube 60 is located higher than the center of the facility installation space 11, it is very important that the water level measurement tube 60 is brought into rapid contact with the inner wall of the facility installation space 11.

The upper end of the wire installation pipe 50 is also preferably located higher than the center of the facility installation space (11). In this case, the wire installation port 15 is preferably close to the pumping connection pipe (30).

This is because there is a need to prevent the wire installation pipe 50 from protruding when placing various facilities or wires in the facility installation space 11.

In FIG. 1, a coupling pipe flange 70 is used to couple the protective case 10 and the pumping pipe.

In addition, the pipe fitting flange 70 has a tube insertion groove 71 is inserted into the upper end of the outer tube (3a) that is located on the outermost side of the well, and the outer tube (3a) of the well is inserted into the tube insertion groove (71) It is welded in one state and is integrated.

This configuration has the advantage that the operation of connecting the protective case 10 and the pumping pipe (1) is very simple.

In other words, the device of the present invention is installed in the well that is completed construction.

Therefore, in order to install the device of the present invention, it is required to dig a deep surface of the well on which the well is installed, and then cut a part of the top of the well and connect the cut well and the protective case 10.

By the way, in the prior art, a considerable inconvenience has arisen in the operation of connecting the upper well cut well and the protective case 10.

The biggest reason for this inconvenience is because of its structural characteristics, it was necessary to cut cleanly horizontally when cutting the top of the well.

However, it is never an easy task to have a clean cutting surface while horizontally cutting a well embedded in the ground.

When the protective case 10 and the well is connected through the well coupling flange 70 having a well insertion hole as shown in FIG. 1, the wells do not need to be cut horizontally and do not have a clean cut surface.

In FIG. 1, a flow passage connecting pipe 80 in which groundwater connector 81 is formed is provided on the side of the protective case 10.

In addition, the flow path connecting pipe 80 is installed to communicate with the inner and outer sides of the protective case 10 through the groundwater connector 81, it is possible to connect the ground water supply pipe (2) from the outer side of the protective case (10). It is to be connected to the pumping connection pipe (30).

This configuration is to facilitate the operation of connecting the pumping pipe in the inner side of the protective case 10 and the ground water supply pipe (2) located on the outer side of the protective case (10).

That is, it is difficult to insert the groundwater supply pipe 2 into the protection case 10 in a state in which the protection case 10 is installed.

In addition, if the ground water supply pipe 2 is inserted into the protection case 10, the sealing work to prevent the inflow of soil or water to the portion into which the ground water supply pipe 2 is inserted is required. Discomfort occurs.
