일반적으로 지하수 심정은 지표의 암반을 소정 굵기의 착정기를 이용하여 암반층까지 굴착한 다음 토사층이나 풍화암층의 붕괴를 막기 위하여 설치되는 대구경의 아웃케이싱과, 상기 아웃케이싱을 박은 다음 다시 암반층을 굴착하여 지하수의 수맥을 관통하기까지 굴착한 후 심정 내부에 설치되는 심정펌프와, 상기 심정펌프와 연결되도록 설치되고 상기 심정펌프에 의해 퍼 올려지는 지하수가 이동되는 양수용 배관으로 구성되어 있다.In general, groundwater core wells are excavated to rock layers using a rocker of a certain thickness, and then out- casing of large diameters installed to prevent the collapse of soil layers or weathered rocks, and the outcasing is applied again to excavate rock layers. After excavating to penetrate the water vein, the heart well pump is installed inside the heart well, and is installed to be connected to the heart well pump and the pumping pipe for moving the groundwater pumped up by the heart well pump.

본 발명은 지하수를 이용하기 위하여 심정을 개발하는 과정에서 발생되는 폐 공이나 기 사용 중인 지하수 심정이 사용목적에 부적합하여 폐기되는 폐공을 원상복구하기 위해 사용되는 폐공팩카를 지하수 심정에 설치시 지하수중에서도 침강속도를 빠르게 할 수 있도록 통수구를 형성하여 수중 침강속도를 개선한 폐공팩커장치에 관한 것이다.The present invention is used in the groundwater at the time of installing the waste hole pack used in the groundwater heart well to recover the waste hole that is generated in the process of developing the heart well to use the ground water or the waste water that is being discarded due to inappropriate use of the ground water heart well. The present invention relates to a waste ball packer device that improves the sedimentation speed in water by forming a water flow port so as to speed the sedimentation speed.

종래 폐공을 원상복구하기 위해 사용되던 폐공팩카는 콘크리트 또는 합성수지 몸체 외부에 원통형의 팽창튜브를 씌워 설치하고 팽창튜브 양 끝에 튜브밴드를 고정하여 팽창튜브에 압축공기를 주입할 때 누설이 없도록 한 상태에서 이를 로우프와 압축공기 주입호스와 함께 지하수 심정 내부에 투입하여 설치위치까지 내린 다음 압축공기를 주입하여 팽창튜브를 팽창시켜 고정한 후 그라우팅용 시멘트를 주입하여 차수벽을 형성시켰다. 그런데 폐공팩카를 지하수 심정 내부에 투입하는 과정에서 폐공팩카의 직경이 지하수 심정 내부 직경의 크기보다 약간 작은 상태로 제작되어지므로 지하수 심정 내부에 충만된 지하수 수중에 투입되는 순간 폐공팩카에 작용되는 부력과 함께 폐공팩카가 침강되면서 하부의 지하수가 상부로 밀려 올라오는 틈새가 작아 결과적으로 폐공팩카의 침강속도가 현저히 떨어지는 문제가 발생되곤 하였다. 이러한 장애를 극복하기 위해 폐공팩커의 직경을 작게 하여 적용하는 경우에는 팽창튜브의 팽창력이 약하여 그라우팅 시멘트액을 주입하는 과정에서 시멘트액의 누설이 발생되는 문제가 발생되었다.The waste hole packer, which is used to restore the original waste hole, is installed by covering a cylindrical expansion tube on the outside of the concrete or synthetic resin body, and fixing the tube bands at both ends of the expansion tube to prevent leakage when injecting compressed air into the expansion tube. This was put into the groundwater core well together with the rope and the compressed air injection hose, lowered to the installation position, and then compressed air was inflated and fixed by inflation, and then the grouting cement was injected to form the order wall. However, in the process of injecting the waste air packer into the groundwater well, the diameter of the waste air packer is made slightly smaller than the size of the inner diameter of the groundwater well. With the sedimentation of the waste hole packka, there was a problem that the sedimentation speed of the waste hole pack was significantly lowered as a result of the small gap between the lower groundwater being pushed upward. In order to overcome such obstacles, when the diameter of the closed air packer is applied to the small diameter, the expansion force of the expansion tube is weak, causing a problem of leakage of cement liquid during the injection of grouting cement liquid.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서,The present invention has been invented to solve the above problems of the prior art,

지하수 심정에 폐공팩커가 설치되는 중에는 통수구를 통해 폐공팩커 하부의 지하수가 폐공팩커 상부로 통수되게 하여 폐공팩커의 부력현상을 막으면서 침강을 원활하게 하여 폐공팩커가 빠른 침강속도를 구현할 수 있는 효과를 갖게하고 지하수 중에 폐공팩커가 잠기게 되면 통수구가 수중에서 팽창이 이루어져 차폐되도록 함으로써 결과적으로 지하수 심정에 폐공팩카가 설치된 위치에서 완벽한 차폐가 이루어지도록 하는 기술을 제공하는데 본 발명의 목적이 있다.While the wastewater packer is installed in the groundwater core, the groundwater from the bottom of the wastewater packer passes through the wastewater packer to the upper portion of the wastewater packer, preventing the buoyancy phenomenon of the wastewater packer and smoothing the sedimentation so that the wastewater packer can realize the fast settling speed. It is an object of the present invention to provide a technique for ensuring that the waste hole packer is locked in the ground water, and the water outlet is expanded and shielded in the water, and as a result, a complete shielding is made at the position where the waste hole packer is installed in the groundwater core.

일반적으로 지하수 심정 중 폐공 처리되는 지하수 심정의 형태는 소정 굵기의 착정기를 이용하여 암반층까지 굴착한 다음 토사층이나 풍화암층의 붕괴를 막기 위하여 설치되는 대구경의 아웃케이싱과, 상기 아웃케이싱을 박은 다음 다시 암반층을 굴착하여 지하수의 수맥을 관통하기까지 굴착하여 형성한 원통형의 깊은 우물 형태를 취하게 된다. 물론 그 내부에 이미 심정펌프와, 상기 심정펌프와 연결되도록 설치되고 상기 심정펌프에 의해 퍼 올려지는 지하수가 이동되는 양수용 배관이 설치되어 있다면 이들 시설은 모두 외부로 인양하여 제거하게 된다. 이렇게 형성된 나공 형태의 지하수 심정을 폐공 원상복구하기 위해 폐공팩커를 정해진 깊이에 내려 설치하게 된다.In general, the groundwater core wells that are closed in the groundwater wells are excavated to a rock bed using a rig of a predetermined thickness, and then out- casing of the large diameter installed to prevent the collapse of the soil layer or the weathered rock layer, and the outcasing and the rock bed again. Excavation takes the form of a cylindrical deep well formed by excavation until it penetrates the veins of groundwater. Of course, if there is already installed inside the heart pump and connected to the heart pump and pumping pipes for moving the groundwater pumped by the heart pump pump these facilities are all lifted to the outside and removed. In order to recover the hole-type groundwater core well formed in this way, the waste hole packer is installed at a predetermined depth.

본 발명의 통수구를 형성하여 수중 침강속도를 개선한 폐공 팩카장치는, 내부 시설물을 모두 외부로 인양하여 제거한 나공 형태로 된 지하수 심정(1) 내부에 폐공팩커(2)를 설치하는 형태로 이루어지게 되며 그 구성은,The waste hole packer device of the present invention has been formed in the form of installing the waste hole packer (2) inside the groundwater core well (1) in the form of a porous hole removed by lifting all the internal facilities to the outside. And the composition is

지수고무원통체로 제작되어 폐공팩커(2) 몸체를 관통하여 형성한 통수구(12)에 삽입 설치되는 통수관체(11)와;A water pipe 11 which is made of a water-resistant rubber cylinder and is inserted into a water outlet 12 formed through the body of the closed hole packer 2;

통수관체(11) 내부에 삽입되고 지지선(8)에 의해 메달려 고정되도록 한 통수구지수봉(9)으로 구성된 것을 특징으로 한다.It is characterized in that it consists of a water passage index rod (9) inserted into the water pipe (11) and hung by a support line (8).

이하 본 발명을 구성 및 작용을 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail.

통수관체(11)는 물을 흡수하면 체적이 팽창되는 지수고무를 원료로 하여 파이프형태로 제작되도록 하였으며 충분한 두께를 형성하여 흡수시 팽창체적을 크게 형성할 수 있도록 하였다. 통수관체(11) 상단에 고정한 지지선(8)에 메달려 고정되도록 한 통수구 지지봉(9) 역시 물을 흡수하면 체적이 팽창되는 지수고무를 원료로 하여 봉형태로 제작되도록 하였으며 그 형태는 구체형태도 무방하다 하겠으나 어떤 형태가 되었건 지하수(3)가 통수하는데 충분한 공간이 확보될 수 있는 크기와 형태가 되도록 하였다. 통수관체(11)는 통수구지지봉(9)의 하단이 위치하는 부분에는 그 직경을 약간 축소하도록 한 축소단부(10)를 형성함으로써 지하수(3) 수중에서 통수구지지봉(9)이 팽창된 이후 주입되는 그라우팅 시멘트액의 하중이 통수구(12) 내부로 유입되어 통수구지지봉(9) 상단에 미친다 할지라도 통수구 지지봉(9)이 아래쪽으로 밀려 내려가기 어렵도록 하였다.The water pipe 11 is made of pipes using water-based rubber that expands in volume when water is absorbed, and forms a sufficient thickness to form a large expansion volume when absorbed. The channel support rod 9, which is hung on the support line 8 fixed on the upper side of the water pipe 11, is also made to be manufactured in the form of a rod by using an index rubber that expands in volume when water is absorbed. Whatever the form, the groundwater (3) was sized and shaped so that enough space could be secured for water to pass through. The water pipe 11 is formed at the lower end portion of the water port support rod 9 by forming a reduced end portion 10 so as to reduce the diameter of the water passage support rod 9 in the groundwater 3. Although the load of the injected grouting cement solution flows into the water inlet 12 and reaches the top of the water passage support rod 9, the water passage support rod 9 is hard to be pushed down.

이와 같이 구성된 통수구(12)를 형성하여 수중 침강속도를 개선한 폐공 팩카장치는 폐공처리되는 지하수 심정(1) 내부에 폐공팩커장치를 투입하여 설치하게 되면 지하수 심정 내벽과 폐공팩커(2) 외주면간의 간극이 좁다 할지라도 통수구(12) 내부를 통해 폐공팩커(2) 아래쪽 지하수(3)가 폐공팩커(2) 상부로 통수되어 올라오게 되면서 폐공팩커(2)의 침강이 원활이 이루어 지게 된다. 폐공팩커(2)의 설치위치가 결정되어지게 되면 팽창튜브(6)에 압축공기를 주입하여 설치가 종료되어지게 되면 그동안 지하수(3) 수중에 잠겨 있게 된 통수관체(11)와 통수구지지봉(9)이 지수고무의 특성에 따라 흡수팽창이 이루어지게 되고 결과적으로 통수구(12) 전체를 차폐하게 된다. 이렇게 됨으로써 폐공팩카(2)의 팽창튜브(6)는 지하수 심정(1) 내벽과 폐공팩카(2)사이를 차폐하게 되고 통수관체(11)와 통수구지지봉(9)은 통수구(12)를 차폐하게 되어 이후 그라우팅 시멘트를 주입하게 되더라도 누설없는 그라우팅이 이루어질 수 있게 되는 것이다.When the waste hole packer device formed in this way to improve the sedimentation speed of the water is formed by putting the waste hole packer device inside the groundwater core well (1) to be disposed of wastewater, the groundwater core well inner wall and waste hole packer (2) outer peripheral surface Even if the gap is narrow, the groundwater (3) below the waste hole packer (2) passes through the inside of the waste hole packer (2), and the sedimentation of the waste hole packer (2) becomes smooth. . When the installation position of the waste air packer 2 is determined, the compressed air is injected into the expansion tube 6, and when the installation is completed, the water pipe 11 and the water port support rod which are submerged in the groundwater 3 9) Absorption expansion is made according to the characteristics of the index rubber, and as a result, the entire water passage 12 is shielded. Thus, the expansion tube (6) of the waste hole pack (2) is shielded between the inner wall of the groundwater core (1) and the waste hole pack (2), and the water pipe (11) and the water pipe support rod (9) is a water hole (12) Since the shielding is then injected with the grouting cement, leak-free grouting can be achieved.

이와 같이, 본 발명에 의한 통수구를 형성하여 수중 침강속도를 개선한 폐공 팩카장치는 통수구를 형성하고 이 통수구를 지수고무를 이용한 통수관체와 통수구지지봉을 이용하여 설치이후 차폐효과를 구현하게 함으로써 폐공팩커의 수중 침강속도를 현저하게 개선시킨 유용하고 효과적인 발명인 것이다.As described above, the waste hole packer device which improves the sedimentation speed in the water by forming the water drainage port according to the present invention forms a water drainage port and implements the shielding effect after installation by using the water flow pipe and the water port support rod using water-resistant rubber. By doing so, it is a useful and effective invention that remarkably improved the sedimentation speed of the waste packer in water.
