Description

Groundwater cardiac treatment device {APPARATUS TO GROUT DEEP WELL}

The present invention relates to a groundwater cardiac treatment device that prevents contamination of groundwater by blocking the inside of a heart well or waste hole that is left to be seriously polluted due to inflow of various pollutants such as leachate or contaminated surface water or soil. A groundwater cardiac treatment device that can be used not only to grout newly-seated heart wells, but also to treat discarded heart wells, that is, waste holes, and can also be used as a catchment or pumping device to draw groundwater through the heart well. It is about.

With the progress of industrialization, water consumption is increasing year by year due to various requests such as drinking water, industrial water, agricultural water, tourism water and so on. Recently, Korea has been designated as a water shortage country. Nevertheless, because the rainfall is concentrated in a certain season in Korea, the available surface water is limited, and even the available surface water is getting worse due to the increase in industrial wastewater and domestic wastewater due to the lack of management. Therefore, in recent years, the development of groundwater has been increasing rapidly because it is relatively clean and can be used immediately without separate water treatment. Groundwater is recognized for its economic value because its quantity is more abundant than surface water and it can be used directly as water without additional water treatment. In addition, the absolute demand for water is increasing rapidly, while the quantity of surface water is limited, and even the limited amount of surface water is deteriorating in the quality of water and the amount of available water is decreasing.

According to this trend, the number of newly-implanted hearts for the purpose of pumping groundwater is increasing. However, the problem is that the number of closed holes is increasing proportionally. However, once groundwater is contaminated, contaminated groundwater rapidly spreads through underground water veins, expanding the affected area to a wider area in an instant, and artificial recovery is almost impossible and takes decades to hundreds of years to restore to its original clean state. The development of groundwater wells should be strictly regulated. In addition, even in the case of a well-depleted heart, that is, a waste hole due to groundwater depletion, failure to develop a well, or pollution, it must be completely closed so that surface water, soil, or other contaminants do not enter the ground vein.

Nevertheless, the development of indiscriminate groundwater wells continues to this day, and the number of boreholes and closed holes that are left without protection facilities is increasing, and groundwater contamination accidents are occurring proportionally, and groundwater pollution prevention measures are urgently required.

Accordingly, the present applicant has proposed a groundwater deep well waste disposal apparatus and its method (patent application No. 97-30649) that can greatly contribute to the prevention of groundwater contamination by allowing easy disposal of boreholes and waste holes at low cost. .

However, this groundwater deep well waste treatment apparatus and its method have been applied to the actual waste air treatment, which has a limitation on the use that it can be used only for waste air treatment, although it can be easily closed at low cost. In other words, groundwater contamination is caused by contaminants such as surface water entering the underground vein through the closed air, and in many cases grouting treatment to block the pollutants on the inner wall of the heart due to the shortening of air and the cost of landing during the development of the heart. However, although the groundwater wastewater treatment device of the prior art is not used for grouting treatment for a newly implanted heart due to the difficulty of installing an underwater motor pump, it can be used only for wastewater treatment. Has a constraint.

Therefore, the present invention can be used not only for the treatment of waste holes, but also for grouting the newly implanted heart well, and can also be used for harvesting or ground water pumping for observing the quantity and quality of the heart well. To provide a cardiac treatment device.

An underwater motor pump may be further installed at a lower end of the pipe, and the underwater motor pump may be supplied with power by a power line introduced through the conduit.

In addition, according to the present invention, the upper and lower ends surrounding the expansion tube may be coupled to the upper and lower plates, respectively, to further provide a guard for preventing the expansion tube from directly rubbing against the inner wall of the heart.

Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments based on the accompanying drawings.

In the accompanying drawings, Figure 1 is a cross-sectional view showing the configuration of a groundwater heart treatment apparatus according to an embodiment of the present invention. And, Figures 2 and 3, 4 and 5 are cross-sectional views showing exemplary use cases of the groundwater heart treatment device according to an embodiment of the present invention, Figures 2 and 3 is an example used for grouting a newly implanted heart well 4 is an example used to collect groundwater to be used as a sample for water quality and quantity inspection of the existing heart well, and FIG. 5 is an example used for groundwater pumping.

As can be seen in Figure 1, the groundwater heart treatment apparatus according to the present invention, the pipe (1) is inserted into the heart well; Upper and lower plates (2, 3) are coupled at a predetermined interval up and down around the lower end of the pipe (1); An expansion tube (4) interposed between the upper and lower plates (2, 3); A fluid injection hose 5 connected to the inlet 4a installed in the expansion tube 4 and drawn out of the heart; A non-return valve 6 installed at the inlet 4a of the fluid injection hose 5 or the expansion tube 4; It comprises a conduit (9) passing through the upper and lower plates (2, 3) and the expansion tube (4). According to the present invention, an underwater motor pump 7 may be further supported at the lower end of the pipe 1. In addition, an elastic guard 10 for protecting the expansion tube 4 from friction against the inner wall of the core 100 may be further installed.

The pipe 1 is inserted into the core and serves as a structural material for supporting the submersible motor pump 7 and other components with respect to the surface, and serves as a pump for allowing the groundwater 101 to be pumped from the ground vein. . When the groundwater cardiac treatment apparatus according to the present invention is used for the purpose of grouting, the hearth together with other components as shown in FIG. 2 for installation of the pumping device after the grouting construction is completed as shown in FIG. 1. 100 is drawn out and removed. In addition, when the groundwater cardiac treatment apparatus of the present embodiment is used for the waste air treatment, after the grouting is completed, the components of the groundwater cardiac treatment apparatus according to the present invention are taken out to close the upper part of the cardiac waste treatment. In this case, when redevelopment is requested in the future, the groundwater of the wastewater treated heart well 100 may be collected through the passage therein, so whether or not the wastewater processed wastewater 100 is recycled through water quality inspection of the collected groundwater. Useful to judge.

The upper and lower plates 2 and 3 are sealing means having an outer diameter approximately equal to the inner diameter of the core 100 coupled to the lower end of the pipe 1 at predetermined intervals, and the expansion tube 4 interposed therebetween. ) And prevents the departure.

In addition, the expansion tube 4 is an elastic tube which is interposed between the upper and lower plates 2 and 3 and is expanded by fluid injection, and an injection hole 4a is formed at one side of the upper surface thereof, and this injection hole 4a is provided. ) Is preferably projected over the upper plate 2 through the upper plate 2. The inlet 4a is connected with a fluid injection hose 5 longer than the depth of the core 100 so as to inject air into the expansion tube 4 from the ground. Then, the non-return valve 6 is employed as a non-return means for preventing the air injected into the expansion tube 4 through the fluid injection hose 5 from flowing backward. The non-return valve 6 is preferably installed in the inlet 4a of the expansion tube 4 or the fluid injection hose 5. Accordingly, the expansion tube 4 is expanded by the air injected into the expansion tube 4 through the fluid injection hose 5 from the ground air injection pump 12, so that the outer peripheral surface of the expansion tube 4 By being in close contact with the inner wall surface of the heart well 100, the upper and lower spaces inside the heart well 100 can be completely blocked. In addition, as the expansion tube 4 is in close contact with the inner wall of the core 100, the components of the pipe 1 and the like are subjected to frictional resistance so that these components do not flow with respect to the inner wall of the core 100. Can be.

For example, after the grouting construction is completed, the air injected into the expansion tube 4 is discharged to the outside by the opening operation of the non-return valve 6, and thus the expansion tube 4 is contracted. Thus, due to the contraction of the expansion tube 4, the expansion tube 4 itself is also released from the fixed state with respect to the inner wall surface of the core 100, but other components are also released from the fixed state with respect to the inner wall surface of the core 100. Therefore, as shown in FIG. 3, the cardiac treatment apparatus according to the present invention can be taken out of the cardiac tablet 100.

Meanwhile, the conduit 9 passes through the upper plate 2, the expansion tube 4, and the lower plate 3 in turn, and passes through the upper plate 2 and the lower plate 3 which are isolated from each other. In the case of the submersible motor pump 7, the power line 8 is inserted through the hollow of the conduit 9 so that the pipe 1 below the lower plate 3 is applied. Power is supplied to the submersible motor pump 7 by being connected to the submersible motor pump 7 installed at the lower end of the motor.

The guard 10 is, for example, a cylindrical protective band made of an elastic material such as rubber, and is fixed by a fixing ring 13 whose upper and lower ends are pressed into and coupled to the upper plate 2 and the lower plate 3, respectively. As a result, the expansion valve 4 is surrounded. Therefore, even when the expansion tube 4 is inserted into the heart well 100, the expansion tube 4 does not directly contact the inner wall of the heart well 100, so that the heart treatment apparatus according to the present invention is installed in the heart well 100. Therefore, the expansion tube 4 may be protected from damage due to friction with the inner wall of the core 100. The guard 10 has a structure that is easy to expand, for example, a thin section in the center and a cross-sectional structure that becomes thicker toward both ends, so that both ends thereof are not separated from the fixing ring 13 when expanded according to the expansion of the expansion tube 4. It is preferable to make. And, as shown in Figure 2, the guard 10 is fixed by the fixing ring 13, which is forcibly fitted to the upper and lower plates (2, 3), but the cardiac treatment apparatus according to the present invention to the heart (100) Other fastenings may also be employed that will not liberate the expansion tube 4 until fully inserted.

On the other hand, the reference numerals 14 and 15 shown in Figure 1 are used in conjunction with the groundwater cardiac treatment apparatus according to the present invention in the process of newly planting the heart well (100), reference numerals 15 and 14 in order to the ground-side soil layer 200 ( 2) in order to prevent the surface water from entering the heart well 100 from the vein 110 existing in the surface soil layer 200 and preventing the surface water from entering into the heart well 100. It shows a casing for shielding the inner wall surface of the cured concrete 15 while forming a sealed space that can be poured into the concrete and the inner wall surface of the core (100). In addition, reference numeral 16 is a flexible pipe connecting the submersible motor pump 7 to the pipe 1, and reference numeral 17 is a reinforcement for reinforcing the bearing capacity of the pipe 1 on the ground surface of the cardiac treatment apparatus according to the present invention. It is a rope.

Next, the operation of the groundwater heart treatment device according to the present invention will be described.

First, the upper and lower plates (2, 3), the expansion tube (4) and the fluid injection hose (5), etc. are installed in the pipe (1), and then the flexible pipe (16) is coupled to the tip of the pipe (1). In addition, the front end of the flexible pipe 16 is connected to the discharge port of the submersible motor pump (7). And, by connecting at least one of the upper surface of the submersible motor pump 7 and the lower plate 3 with a rope 11 to support the submersible motor pump 7 to the lower end of the pipe (1). Then, the power supply line 8 is inserted into the conduit 9 protruding upward from the outside of the upper plate 2 and drawn out to the underwater motor pump 7 to connect the power supply line 8 to the underwater motor pump 7. . In the process of installing the groundwater heart treatment device according to the present invention for the purpose of water collection or pumping, to install the components such as flexible pipe 16, submersible motor pump (7), rope (11), power line (8) The operation is omitted.

The above assembly is taken up to a depth that can secure an appropriate level of water quality and quantity while collecting ground water with the submersible motor pump 7 at the tip of the pipe (1) at the center of the pipe (100). Insert it. Next, the casing 14 is inserted into the core 100 so that its tip overlaps with the expansion tube 4, and then the fluid injection hose 5 drawn out of the core 100 is removed from the air injection pump 12. By injecting air into the expansion tube 4 and expanding the expansion tube 4 by operating the air injection pump 12. When the expansion tube 4 is expanded as described above, the casing 14 and the other components constituting the groundwater cardiac treatment apparatus according to the present invention are subjected to the core feeling by frictional resistance to the inner wall surface of the core 100 of the expansion tube 4. It may be temporarily fixed within the 100. Subsequently, when the concrete 15 is poured and cured in the space between the casing 14 and the inner wall 100 of the core, the soil layer inside the core 100 is doubled by the cured concrete 15 and the casing 14. It is blocked so that it can not flow into the heart (100). When the grouting construction is completed, the expansion valve 4 and the guard 10 are shrunk by opening the non-return valve 6 to discharge the air injected into the expansion tube 4 to the outside through the fluid injection hose 5. Next, as shown in FIG. 3, the groundwater heart treatment device according to the present invention may be drawn out of the heart well 100.

By using the groundwater cardiac treatment apparatus according to the present invention as described above, the grouting construction for the newly-seated heart well can be easily performed.

That is, the groundwater heart treatment apparatus according to the present invention is fixed or flowable to the inner wall surface of the heart well 100 by expansion and contraction of the expansion tube 4 according to the injection or discharge of air to the expansion tube (4). Since it can be inserted into the heart well 100, it can be usefully used to take the groundwater for each section of the heart well (100). In this case, the water motor pump 7 must be installed as described above. According to the operation of the submersible motor pump (7), it is possible to grasp the groundwater quality and quantity through the inspection of the groundwater collected through the pipe (1) for each section in the heart well, so that the optimal groundwater quality and quantity can be secured. You can find the depth of your.

5 is a view showing that the groundwater cardiac treatment apparatus according to the present invention can be used simultaneously for grouting construction and groundwater pumping, the cardiac treatment according to the present invention for the grouting construction of the newly laid heart well 100 as described above. After the grouting construction using the device is finished, the cardiac treatment device according to the present invention can be used as a pumping device for continuously pumping ground water by leaving the cardiac tablet 100 without drawing out. At this time, the diameter of the two-way joint structure (Reducer) (1a) that can increase and reduce the area of the pumping passage along the pipe (1) to increase the buoyancy force to the groundwater can be employed.

In addition to the use cases as described above, the groundwater treatment system according to the present invention can be usefully used to treat waste holes so that groundwater is not contaminated. That is, the waste air treatment process is similar to the grouting process except the landing process.

As described above, when the cardiac well 100 is closed by the groundwater cardiac treatment apparatus according to the present invention, the underground vein can be observed and the groundwater can also be collected and inspected. In addition, if it is necessary to re-develop the closed hole after the closed hole treatment, the existing pipe 1 can be used as a positive pump, and when a larger positive pipe is to be used, the pipe 1 and the pipe 1 The upper and lower plates (2, 3) of) are damaged by impact, and then the concrete 15 can be crushed and discharged through the hole where the pipe 1 is installed, and a new pump pipe can be inserted to redevelop the closed hole. Very easy.

As described in detail above, the groundwater cardiac treatment apparatus according to the present invention may be used to process the heart well 100 in a closed air, as well as to be useful for grouting construction for a newly laid heart. The scope of application is very wide, such as it can be used for harvesting water to monitor the quantity and water quality of pre-determined heart wells or groundwater pumping.

In addition, the expansion tube 4 is protected from damage due to friction with the inner wall of the core 100 by the guard 10 in the process of processing the core 100, so that the pipe 1 may be damaged by the expansion tube 4. Construction can also be very easy because it can be easily inserted into the heart (100). Therefore, it can greatly contribute to reducing the labor and construction period required for grouting construction or vacancy treatment of the core (100). In addition, since the case of the grouting construction can be greatly reduced because of cost savings and air shortening when the new core 100 is settled, it can also greatly contribute to reducing the contamination of groundwater.
