The present invention is a groundwater heart grouting casing device and grouting method using a positioning detection function configured to cure concrete in the inner wall of the heart to prevent the inflow of contaminated surface water, etc. to the ground excavated in order to collect the ground water, and perfect the inside of the heart In addition to this, it is possible to perform a perfect grout without contaminating the groundwater or blocking the groundwater vein.

As is well known, as industrialization progresses in modern times, environmental pollution is intensifying and interest in clean drinking water is increasing. Therefore, in recent years, researches on devices for purifying tap water or surface water and devices for developing uncontaminated groundwater have been intensified.

In general, the conventional groundwater harvesting device is not shown in the drawings, but the excavation of the weathered rock layer to the rock layer by using a rocker of a predetermined thickness to the rock layer of the large diameter is installed to prevent the collapse of the weathered rock layer, and the Out casing and then excavate the rock bed again to penetrate the water vein, and then the in casing installed to prevent the inflow of surface water, and the groundwater sediment A strainer pipe installed to prevent inflow, concrete cured and injected to prevent inflow of foreign matter such as surface water into the space between the encasing and the groundwater inner wall, and a heart pump installed inside the encasing; Groundwater installed to be connected to the heart pump and pumped up by the heart pump It consists of pumping pipe to be moved.

The prior art is similar to the Utility Model Registration Application No. 1999-11547 filed by the present applicant (previous name: Excavation bit induction device for groundwater deep well equipped with expansion tube), but the conventional technology A problem arises in that the grouting casing cannot be installed accurately in the inner center.

Therefore, due to the grouting casing can not be accurately installed in the inner center of the heart has a problem that the cement mortar can not be cured correctly.

In addition, there is a problem that there is no device to shield the inside of the heart secondary to the damage of the packing.

The present applicant also has a previously filed Utility Model Registration No. 2000-8714 (designated name: corrugated pipe groundwater core encasing pipe connecting socket), but the prior art simply connects only the grouting casing to the outer peripheral surface. There is a problem that the grouting casing can not be correctly installed in the center of the heart because there is no structure to hold the hose.

In addition, in the case of a grouting casing device using an expansion tube, the expansion tube is generally installed at the outer periphery of the grouting casing device, and the expansion tube is externally impacted and scratched in the process of inserting the deep depth inside the deep water well. There was a problem that frequently exposed to the damage accident occurs frequently. In order to prevent damage of the expansion tube, a protective cover was installed, but a fundamental problem could not be solved.

In order to compensate for this problem, the expansion tube at the point where the grouting casing device ends by mounting the internal expansion packer into the grouting casing device after mounting the grouting casing device or inserting the grouting casing device into the grouting casing device is completed. The grouting liquid injected by inflating the gas was prevented from entering the groundwater well, but the groundwater inside the groundwater well was turbidly in the process of checking the input position through the underwater camera. Even in the process of determining the location of the internal expansion type packer through actual measurement of the lower part, it is difficult to check the optimal insertion depth and the fixed position of the internal expansion type packer which is injected into the grouting casing due to the measurement error. difficulty It was often the job to fail.

The present invention has been invented to solve all the problems of the prior art as described above, and the first object of the present invention is to completely shield the grouting casing and the groundwater core by an expansion tube. As a result, it is possible to perform a smooth grouting without contaminating groundwater or blocking the veins of the groundwater. The third purpose is to check the optimum position of the grouting casing by installing a positioning detector inside the internal expansion type packer. The fourth purpose is to make it easy to determine the fixed position of the internal expansion type packer, and the fourth objective is to install the grouting casing accurately in the center of the well by matching the center of the internal part of the grouting casing with the center of the groundwater core. And the fifth purpose is to It provides groundwater deep grouting casing device and grouting method using location detection function that can greatly improve product quality and reliability.

In order to achieve the above object, the present invention provides a groundwater core grouting casing device using a positioning detection function for making a shielding wall installed in an excavation hole to prevent the inflow of surface water contaminated with groundwater core wells. Each hole is drilled with a caliber, and the grouting casing is inserted between the large and small diameters, and the internal expansion type packer is inserted into the grouting casing in accordance with the metal recognition buzzer of the positioning detection sensor to fix the position and inject the compressed air. By expanding the expansion tube to shield the groundwater heart inside and the grouting casing provides a groundwater heart grouting casing device using a positioning detection function to completely block the inflow of contaminated ground water through the injection and curing of grouting liquid.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention for achieving this purpose are as follows.

The groundwater core grouting casing apparatus using the metal detection function applied to the present invention is configured as shown in FIGS. 1 to 3.

In the following description of the present invention, if it is determined that specific descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The following terms are terms set in consideration of functions in the present invention, which may vary depending on the intention or custom of the producer, and their definitions should be made based on the contents throughout the specification.

First, an embodiment of the present invention relates to a groundwater deep well grouting casing apparatus using a positioning detection function for making a shielding wall installed in an excavation hole to prevent the inflow of surface water contaminated with groundwater wells, in particular, the groundwater deep well diameter Perforations 30 and small diameter 1, respectively, and insert the grouting casing (2) of the same size as the diameter of the small diameter (1). At this time, there is a gap between the grouting casing (2) and the groundwater core excavated with a large diameter (1) and is configured to cure by injecting a grouting material from the bottom to this gap.

In addition, the lower outer periphery of the grouting casing (2) is equipped with a positioning indicator (3) is planned in the grouting casing (2) by the positioning detection sensor unit 4 built in the internal expansion type expansion pack (5) Checking the position, the internal expansion type packer (5) to fix the position, followed by injecting compressed air into the expansion tube (6) to expand the expansion tube (6) and consequently shields the grouting casing (2) and the groundwater core Configure it to do so. The positioning indicator (3) installed on the outer periphery of the grouting casing (2) may use a transmitting device that checks the position using an induction electromotive force by a magnetic field using a permanent magnet tape or transmits an electro-electric signal that has been waterproofed. This is configured to be able to easily check the close proximity by the operation of the positioning detection sensor unit (4). Of course, if the positioning indicator (3) is a permanent magnet tape, or when attaching a transmission device for transmitting an electrical signal, the grouting casing (2) in the process of inserting the inside of the groundwater wells friction and impact with the groundwater well wall It is configured to install a separate protective cover 27 on top of the positioning indicator (3) in order to prevent the fall or damage by. Power supply for the operation of the positioning detection sensor unit (4) to function through the battery having a waterproof function inside the internal expansion type packer (5) or to have a power supply function with the signal cable (19) from the outside of the ground It can also be configured by connecting cables. Of course, if the positioning indicator (3) requires a power source for signal transmission can be configured by mounting a small battery. When the positioning indicator 3 is attached in this way, the material of the grouting casing 2 does not necessarily have to be made of stainless steel pipe, and it is possible to use a steel pipe made of synthetic resin. In addition, in order to check whether the grouting material 12 leaks in the process of injecting the grouting material 12, an illumination lamp 22 is provided at the lower end of the inner rod-type expansion packer 5 by the support bar 23. It can be operated by installing the underwater camera (7) that is installed and can be confirmed from the outside by the monitor (9). Of course, for this purpose, the power line 24 and the underwater camera cable 28 were configured to receive power and a signal to the underwater camera 7. The inner toothed packer 5 inserts the expansion tube 6 into the outer periphery of the inner toothed packer 5 and fixes both ends with the tube band 21 to inject compressed air through the injection hose 26. Leakage in the expansion tube (6) of the configuration is configured so that the tow line 10 is fixed to the lifting ring (18) to lower or pull up from the outside. The connection between the internal expansion type packer 5 and the injection hose 26 is coupled using the injection nipple 25.

According to the present invention configured as described above, the grouting casing 2 with the positioning indicator 3 is installed inside the groundwater core well, and then the grouting casing is provided with the internal expansion-type expansion packer 5 having the positioning detection sensor unit 4 therein. (2) When it is inserted and lowered inside, when the positioning indicator 3 approaches the depth where it is located, the signal transmitted through the signal cable 19 starts ringing and the buzzer installed in the marker 8 starts to ring. It becomes bigger. At this time, if it is confirmed through a digital display window or an analog guide installed on the marker 8, the closest position can be confirmed, and the identified depth is a position at which the internal expansion type expansion packer 5 is fixed. By expanding the expansion tube (6) of the internal tooth type expansion packer (5) in the identified position can bring about the effect of tightly shielding between the groundwater core and the grouting casing (2). Of course, in the shielded state, the grouting material 12 is driven from the lower part of the grouting casing 2 through the grouting injection hose 13 by operating the grouting pump 12 in the gap between the groundwater core wall and the outer peripheral surface of the grouting casing 2. By injecting and curing, it is possible to form a subsurface protective wall that can block the inflow of contaminated groundwater.

Of course, in the case where the internal expansion type packer 5 has only a metal detection function, the grouting casing 2 is generally made of stainless steel, so that the positioning detection sensor part 4 is located at the bottom of the grouting casing 2. When the metal detection sensing is finished, the alarm sounding stops or the measurement value of the instrument is displayed as the value where no metal part is found, so that the lowest part of the grouting casing (2) can be easily checked. By expanding the expansion tube (6) of the packer (5) it can bring about the effect of tightly shielding between the groundwater core and the grouting casing (2). The bottom of the grouting casing (2) was constructed with a reinforcement structure by applying an annular reinforcement ring (17) to prevent damage or bending at the end during insertion into the groundwater well. In addition, the grouting casing (2) is generally made of stainless steel pipe, but if the casing connected to the upper is used as a pipe pipe, it uses a connecting socket 15 made of stainless steel, and the connection coupling with the pipe pipe is non- The three holes 16 were coupled to each other using screws.

Of course, in the shielded state by injecting and curing the grouting material 12 in the gap between the groundwater core wall and the outer peripheral surface of the grouting casing (2) it can be configured of the subsurface protective wall that can block the inflow of contaminated groundwater. Of course, when the curing is completed, the compressed air injected into the expansion tube (6) to the outside to shrink the expansion tube (6) and then pull the internal extension type packer (5) to pull the pull line (10) to the outside device The whole is drawn out and removed.

In addition, in the process of inserting and fixing the internal expansion type packer 5 inside the grouting casing 2 and injecting compressed air, the internal expansion type packer 5 naturally grouts the casing by the expansion force of the expansion tube 6. (2) is fixed while being located in the center of the grouting casing (2) it is possible to achieve the purpose of matching the center of the inner circumferential surface and the center of the groundwater core jungjung through the expansion of the internal expansion type expansion pack (5) as a result Due to the configuration and operation results as described above, it is possible to provide a groundwater heart grouting casing device and a grouting method using a positioning detection function that can greatly improve the quality and reliability of the product.
