Description
본 발명은 지하수 굴착공 오염방지와 구간 막음용 차폐 장치 및 방법에 관한 것으로, 더욱 상세하게는 지하수 굴착공(지하수 관정, 지하수 수질측정망, 지열 지중열교환기 굴착공 등)의 상층부에서 유입되는 오염된 지하수의 유입을 차단하거나 일부 오염에 의해 탁도나 오염인자가 극심하게 유입되는 구간에 대한 오염지하수 차단을 위한 구간차폐가 가능한 지하수 굴착공 오염방지와 구간 막음용 차폐장치 및 방법에 관한 것이다.More particularly, the present invention relates to a shielding apparatus and method for preventing contamination of groundwater drilling holes, and more particularly, to a shielding apparatus and method for preventing contamination of groundwater drilling holes, The present invention relates to an apparatus and method for preventing contamination of an underground water drilling hole and a method for shielding a groundwater, which can shield a ground for interception of contaminated ground water, in a section where turbidity or contamination factor is extremely inflowed by interception of groundwater or partial pollution.
호수나 댐건설을 통한 인공호수, 하천이나 강물 등 지표수는 인류의 물 사용량의 폭발적인 증가로 이미 그 고갈이 예견되고 있으며 대한민국 역시 미래의 물 기근 국가로 분류되어 있는 실정이다. 이에 따라 지하수는 미래 인류의 새로운 수자원으로서 조명되고 있으며 한국 또한 지하수의 사용량이 계속 증가 추세에 있어 그 사용량 비율이 전체 용수 사용량의 약 10%에 육박하고 있으나 선진각국의 개발 현황과 대비하여 보면 향후 국내 지하수 사용 비율은 지속적으로 증가되어 20%를 상회할 것이라는 예측이 가능하여 현재의 지하수 사용량에 비해 약 2.5배가 넘는 약 60억 톤의 개발 잠재량을 보유하고 있다고 분석되고 있다.Surface water, such as artificial lakes, rivers and rivers, through the construction of lakes and dams, is expected to be depleted due to the explosive increase in water use by humankind, and Korea is also classified as a future water famine nation. As a result, groundwater is being illuminated as a new water source for future humans, and the usage rate of groundwater in South Korea is on the rise, and the rate of its use is close to 10% of total water use. However, It is estimated that the groundwater use rate is steadily increasing to exceed 20%, which means that it has a development potential of about 6 billion tons, which is about 2.5 times that of current groundwater use.
그러나 국가의 중요한 지하자원의 하나로서 후세에 길이 물려줄 지하수가 개발과정과 사용과정에서 제대로 관리되지 못함으로써 고갈되어지고 재개발에 따른 무분별한 굴착 등으로 인해 황폐화 되어가고 있다는 것은 국가적 재앙이라 해도 과언이 아닐 것이다.However, it is not an exaggeration to say that one of the important underground resources of the country is being depleted due to the depletion of underground water that will be passed down to the future, will be.
종래 지하수 심정이나 수질측정망, 지열 지중열교환기용 굴착공을 형성하는 과정에서 상층 오염지하수의 유입을 방지하여 지하수 수질을 보전하기 위해서 지표하부보호벽(케이싱)을 암반선 1m 이상 깊이까지 삽입설치하고 5cm 이상 두께로 차수벽을 형성하도록 규정하여 시행하고 있다. 이때 사용되어 온 차폐장치는 압축공기를 주입하면 팽창되는 팽창튜브를 케이싱 하단에 결합하여 목표깊이까지 삽입설치하고 압축공기를 주입하여 굴착공 공벽과 케이싱 사이를 차폐할 수 있도록 한 후 속경성시멘트를 주입하여 신속히 경화시킴으로써 효과적인 차폐가 달성되도록 하였다. 또한 다른 차폐장치는 상호 슬라이딩이 가능한 케이싱 사이에 압축이 변형이 가능한 원통형 압축튜브를 끼워 설치한 후 목표깊이까지 내려 설치된 상태에서 안전잠금장치를 해제한 후 압박하여 케이싱이 상호 슬라이딩하면서 수축하는 과정에서 압축튜브의 형태가 오므라지면서 굴착공 공벽과 케이싱 사이를 차폐하였다.In order to prevent the inflow of the upper ground contaminated groundwater in the process of forming the excavator for the groundwater intrusion, water quality measurement network and geothermal underground heat exchanger, the lower surface protection wall (casing) is inserted to the depth of 1m or more, And to form a water wall with a certain thickness. When the compressed air is injected into the shielding device, the expansion tube, which is inflated, is connected to the lower end of the casing, inserted to the target depth, compressed air is injected to shield the gap between the excavation air hole and the casing, Injection and rapid curing to achieve effective shielding. In addition, the other shielding apparatuses are provided with a cylindrical compression tube capable of being deformed by compression between casings capable of being slidable, and after releasing the safety lock device in a state of being lowered to a target depth, The shape of the compression tube was disturbed and shielded between the excavated air wall and the casing.
이러한 형태는 모두 케이싱과 굴착공 공벽을 효과적으로 차폐할 수 있는 효과가 있었던 반면에 팽창튜브의 경우 굴착공 내부에 삽입되는 과정에서 팽창튜브가 파손되는 일이 잦아 작업성이 크게 떨어지는 문제가 있었으며 압축튜브의 경우에는 케이싱을 압축하여 슬라이딩시키는 과정에서 케이싱 하단이 굴착공 바닥에 위치하여 버팀이 가능하거나 별도의 케이싱을 잡아주기 위한 로프를 설치하여야 하는 문제점이 있었다. In the case of the expansion tube, there is a problem that the expansion tube is broken frequently in the process of being inserted into the excavation hole, so that the workability is greatly reduced, and the compression tube The lower end of the casing is positioned at the bottom of the excavation hole in a process of compressing and sliding the casing, and thus it is necessary to install a rope to support the casing or to hold a separate casing.
한편, 본 발명과 관련된 선행기술로서 본 발명인에 의해 발명되어 특허받은 대한민국 특허 제0334451호(특허명칭 : 지하수 심정의 그라우팅 파이프장치 및 그라우팅 방법)외 다수의 특허와 실용신안을 출원 등록한 바 있으며 현장에서의 성공적인 기술접목과 사업화를 달성하여 국가 지하수 개발과 오염방지 관련 분야에 공헌하여 온 바 있다. Meanwhile, as a prior art related to the present invention, Korean Patent No. 0334451 (patent name: a grouting pipe device and a grouting method of groundwater aqueduct) invented and patented by the present inventor and many other patents and utility models have been filed and registered And has contributed to the development of national groundwater and pollution prevention related fields.
종래 기술은 지하수 심정 벽체와 그라우팅 케이싱 외주면과의 다양한 간격에서도 높은 차폐성을 확보할 수 있어 그 기술의 우수성에 대한 평가가 높아 신기술로 인정됨과 동시에 국가 지하수업무수행지침서에 등재됨은 물론 제주도의 경우에는 특별법 제정을 통해 적용의 강제를 취하고 있기도 하다. 그러나 전술한 바와 같이 팽창튜브의 특성상 팽창을 시키기 위해서는 압축공기의 주입이 필요하고 지표로부터 통상 30미터 또는 그 이하의 깊이까지 그라우팅 케이싱에 장착하여 투입하여야 하는 과정에서 지하수법에서 규정하고 있는 그라우팅 두께가 50밀리미터(mm)밖에 이르지 않는 간극이 좁은 지하수 심정 벽체와의 마찰과 충격으로 파열될 수 있는 가능성이 늘 존재하고 있었던 문제가 있었다. 또한, 수직상으로 설치되는 특성 상 팽창튜브에는 물을 주입하여 팽창시키게 되면 수두압현상(물 높이10미터당 약1.033킬로그램/제곱센티미터 압력 발생)으로 지하수 심정마다 일정하지 않은 지하수 수위로 인해 계획된 정확한 팽창력을 조정하거나 확보하기 어려운 문제가 있어 이러한 불편을 해소하기 위해 압축공기를 사용하게 되는데 압축공기의 압력은 팽창튜브가 연질의 팽창성이 높은 특성 상 0.1킬로그램/센티미터 이상에서도 팽창이 시작됨으로 팽창튜브가 설치된 깊이에서 지하수 수위를 뺀 깊이에 수두압을 고려하여 적정 공급 공기압력을 결정하여야 하기 때문에 장치를 처음 접하는 초보자들은 어려워하는 문제가 있을뿐더러 이론보다는 실무에 더 비중을 두고 있는 지하수 개발업체에 직접 공급하여 시공하는 과정에서는 이러한 기술의 이해와 현장적응이 어렵다는 현실을 확인하였으며 이러한 이유로 인해 보다 폭 넓은 기술적용에 한계를 가지고 있을 수 밖에 없었다.The prior art is recognized as a new technology because it has high evaluation of the superiority of the technology because it can secure high shielding ability at various intervals between the groundwater wall and the outer circumferential surface of the grouting casing. In addition, It is also enforcing enforcement through enactment. However, as described above, in order to expand the characteristics of the expansion tube, it is necessary to inject compressed air and the grouting thickness specified in the groundwater method is required to be set in the grouting casing after being inserted into the grouting casing from the surface to a depth of 30 m or less There is always a possibility that a gap of only 50 millimeters (mm) can be ruptured due to friction and impact with a narrow groundwater wall. In addition, due to the fact that water is injected into the inflation tube in the vertical direction and inflated, the water pressure phenomenon (about 1.033 kg / cm of pressure per 10 meters of water height) The pressure of the compressed air is such that the expansion tube starts to be expanded even when the expansion tube is soft and has a high expanding characteristic of 0.1 kg / cm or more. Therefore, Since it is necessary to determine the proper supply air pressure considering the water head pressure at the depth minus the ground water level, it is difficult for the novice who is new to the apparatus to have difficulty, and also it is supplied directly to the underground water development company In the process of construction, It was confirmed that the adaptation to the sun and the field was difficult, and for this reason, we had to limit the application of a wider range of technologies.
또한, 대한민국 특허 제 10-0715746호(특허명칭 : 지하수 심정 오염방지를 위한 그라우팅장치 및 그 시공방법)는 지하수 심정에 오염된 지표수가 유입되지 못하도록 지표하부보호벽을 구성하는 장치와 시공방법을 발명한 바 있으나 이 장치와 방법은 인케이싱과 아웃케이싱 사이 간극의 하부면을 차폐하도록 환형의 정착 플레이트와, 정착 플레이트 상면에 안착되며, 분할된 구조체로서 이격거리가 멀어짐으로써 인케이싱 외주면과 아웃케이싱 내주면에 각각 밀착되도록 수성한 인너팩킹 및 아웃터팩킹, 그리고 인너팩킹과 아웃터팩킹의 이격거리를 제어하는 제어수단으로 구성된 장치로 구성되어 있다. 그러나 이는 그라우팅을 위해 사용되는 인케이싱과 지하수 굴착공벽이 극이 좁은 공간에서는 인너팩킹와 아웃터 팩킹이 그 기능을 다하지 못할 수 있는 한계를 가질 수 밖에 없으며 인케이싱과 지하수 굴착 공벽의 간극의 크기에 따라 인너팩킹과 아웃터팩킹의 두께 값을 수시로 조정 설치해야 하는 불편함이 따를 수밖에 없는 문제를 안고 있음은 물론, 웨지부재를 삽입하기 위해서는 인너팩킹과 아웃터팩킹의 높이를 제한 할 수 밖에 없는데 그 결과 차폐의 길이가 짧아지게 되어 차폐면적이 작아지게 됨으로써 효과적인 차폐의 성능을 확보하기에는 부족함이 있을 수 밖에 없었다. 더욱 중요한 것은 인너팩킹과 아웃터팩킹 간의 이격거리를 제어하기 위한 제어수단인 웨지부재를 통상 50밀리미터 내외로 좁게 형성된 인케이싱과 지하수 굴착 공벽의 사이의 간극에서 어떻게 작동시킬 것인가에 대한 고찰이 전혀 없다는 문제점을 가지고 있다.Korean Patent No. 10-0715746 (entitled "Grouting Apparatus for Preventing Contamination of Groundwater Waters and Its Construction Method") discloses an apparatus and a method of constructing a lower surface protection wall so that surface water contaminated with groundwater can not be introduced This apparatus and method are mounted on an upper surface of an anchor plate and an annular fixing plate for shielding the lower surface of the gap between the enceasing and the out casing and are separated from each other by a separated structure so that the inner circumferential surface An inner packing and an outer packing which are made to be in close contact with each other, and a control means for controlling a separation distance between the inner packing and the outer packing. However, this is because the ingaking and underground water excavation used for grouting has a limitation that the inner packing and the outer packing can not fulfill the functions in the narrow space, and depending on the size of the gap between the incising and the ground water excavation wall, There is a problem that the thickness and thickness of the packing and the outer packing must be adjusted from time to time. In addition, in order to insert the wedge member, the height of the inner packing and the outer packing must be limited. As a result, The shielding area becomes short, which is insufficient to ensure effective shielding performance. More importantly, there is no consideration as to how to operate the wedge member, which is the control means for controlling the separation distance between the inner packing and the outer packing, from the gap between the narrowing of the wedge member, usually about 50 millimeters, Lt; / RTI >

물론, 압축튜브(20)와 압축 코일스프링(30) 및 릴리즈수단(40)의 설치를 위하여 별도의 차폐관을 사용할 수도 있다. 즉, 압축튜브(20)와 압축 코일스프링(30) 및 릴리즈수단(40)이 둘레부에 설치된 별도의 차폐관을 케이싱(10)의 사이에 관이음하는 방법, 압축튜브(20)와 압축 코일스프링(30) 및 릴리즈수단(40)이 설치된 별도의 차폐관을 케이싱(10)의 외부에 덧대는 방법으로 사용할 수 있다.Of course, a separate shielding pipe may be used for installing the compression tube 20, the compression coil spring 30 and the release means 40. That is, there is a method in which a separate shielding tube provided around the compression tube 20, the compression coil spring 30 and the release means 40 is inserted between the casing 10 and the compression tube 20, A separate shielding tube provided with the spring 30 and the release means 40 may be used as a method of attaching the shielding tube to the outside of the casing 10. [
케이싱(10)은 릴리즈수단(40)의 릴리즈핀(41)이 고정되는 핀홀(11)이 형성된다. 핀홀(11)은 케이싱(10)을 관통하는 홀, 홈, 턱 등을 포함한다.The casing 10 is formed with a pinhole 11 to which the release pin 41 of the release means 40 is fixed. The pinhole 11 includes a hole, a groove, a jaw, and the like which penetrate through the casing 10.
케이싱(10)의 둘레부에는 케이싱(10) 및 케이싱(10)의 둘레부에 설치되는 구성들을 보호하고 굴착공(1)의 중심에 배치될 수 있도록 간극부재(13)가 형성된다. 간극부재(13)는 케이싱(10)의 상부와 하부에 각각 케이싱(10)의 둘레부로부터 돌출 형성되며 각각 원주방향을 따라 일정 간격을 두고 다수개가 돌출 형성된다. 케이싱(10)은 압축튜브(20)와 압축 코일스프링(30) 및 릴리즈수단(40)의 작동 상태를 외부에서 확인할 수 있도록 점검창이 포함되며, 상기 점검창은 개방된 형태, 투명의 유리창 형태 등이 가능하고 수중 카메라를 케이싱(10) 내부에 삽입하여 상기 점검창을 통해 압축 코일스프링(30)과 릴리즈수단(40)의 작동 상태를 촬영하고 지상에서 모니터를 통해 촬영된 영상을 확인한다.A gap member 13 is formed at the periphery of the casing 10 so as to protect the casing 10 and the structures provided at the periphery of the casing 10 and to be disposed at the center of the excavation hole 1. The gap member 13 protrudes from the periphery of the casing 10 at the upper and lower portions of the casing 10, and a plurality of the gap members 13 are formed at predetermined intervals along the circumferential direction. The casing 10 includes a check window for checking the operation state of the compression tube 20, the compression coil spring 30 and the release means 40 from the outside, and the check window may be opened, And an underwater camera is inserted into the casing 10 to photograph the operation state of the compression coil spring 30 and the release means 40 through the inspection window and confirm images photographed on the ground from the monitor.
즉, 본 발명에서 설명하는 케이싱(10)은 양수를 위한 일반적인 케이싱, 상기 일반적인 케이싱에 결합되는 별도의 차폐관 모두를 포함하는 것이다.That is, the casing 10 described in the present invention includes both a general casing for positive water and a separate shielding tube coupled to the general casing.
압축튜브(20)는 압축 코일스프링(30)으로부터 가해지는 힘에 의해 압축되어 횡방향으로 팽창[설치상태를 기준으로 하여 압축 코일스프링(30)으로부터 가해지는 수직방향의 힘에 의해 굴착공(1)의 벽면을 향해 횡방향으로 변형되는 것을 말함]하여 둘레부가 굴착공(1)의 내벽면에 밀착됨으로써 굴착공(1)을 차폐한다. The compression tube 20 is compressed by the force applied from the compression coil spring 30 and is expanded in the lateral direction by a force in the vertical direction applied from the compression coil spring 30 The circumferential portion is in close contact with the inner wall surface of the excavation hole 1 so as to shield the excavation hole 1.
압축튜브(20)는 대체로 인체나 수질에 영향을 미치지 않는 실리콘이 사용되나 팽창성이 없는 섬유재질이나 가죽, 합성수지필름 등을 적용하여 운용할 수도 있다. The compression tube 20 generally uses silicone which does not affect the human body or water quality, but may be operated by applying a non-expandable fiber material, leather, synthetic resin film, or the like.
또한, 압축튜브(20)는 지하수에 의해 팽창하는 수팽창 재질, 수팽챙재질의 지수링과 함께 적용되는 것도 가능하다.In addition, the compression tube 20 may be applied together with an expansive material that expands by groundwater, or an exponent ring of a water-swellable material.
압축튜브(20)는 케이싱(10)과 접촉에 따른 마찰저항을 줄이기 위하여 내주면이 윤활처리되며, 예를 들어 폴리에틸렌 필름층이 형성될 수 있다.The inner circumferential surface of the compression tube 20 is lubricated in order to reduce the frictional resistance with contact with the casing 10, for example, a polyethylene film layer may be formed.
압축튜브(20)는 일측이 전술한 것처럼 압축 코일스프링(30)과 연결되며 타측이 케이싱(10)에 고정[용접, 케이싱(10)에 고정된 고정 플랜지(12)에 의한 끼움, 고정 플랜지(12)를 케이싱(10)에 용접 등)된다. One end of the compression tube 20 is connected to the compression coil spring 30 and the other end of the compression tube 20 is fixed to the casing 10 (welding, fitting with the fixing flange 12 fixed to the casing 10, 12 is welded to the casing 10 or the like).
압축튜브(20)는 재질의 특성상 용접이 불가능하고 압축 코일스프링(30)의 압축시 손상을 일으킬 수 있으므로 이를 보완하기 위하여 예컨대 스틸 재질의 밴드(21,22)가 적용될 수 있다.Since the compression tube 20 can not be welded due to the characteristics of the material and can cause damage when the compression coil spring 30 is compressed, for example, bands 21 and 22 made of steel can be applied to compensate for this.
밴드(21,22)는 각각 압축튜브(20)의 단부를 감싸도록 일측이 개방된 구조(내부와 외부를 함께 감싸는 구조)가 바람직하고, 내부와 외부의 길이는 다양하게 조정 가능하다. 또한 밴드(21,22)는 자체 강도 보강과 압축튜브(20)의 결속력 증대를 위하여 단부에 컬링부(21a)가 구비될 수 있다. 밴드(21,22)는 압축튜브(20)보다 큰 외경으로 구성되어, 설치시 압축튜브(20)가 굴착공(1)의 공벽과의 마찰에 의해 손상되지 않도록 보호하는 기능도 겸한다.Each of the bands 21 and 22 preferably has a structure in which one side is opened so as to enclose the end of the compression tube 20 (a structure for enclosing the inside and the outside together), and the lengths of the inside and outside are variously adjustable. In addition, the bands 21 and 22 may be provided with curled portions 21a at their ends to reinforce their own strength and to increase the binding force of the compression tube 20. The bands 21 and 22 are formed to have an outer diameter larger than that of the compression tube 20 so as to protect the compression tube 20 from being damaged by friction with the air hole of the excavation hole 1 at the time of installation.
상부측의 밴드(21)는 슬라이더(50)에 용접 등으로 고정되고, 하부측의 밴드(22)는 케이싱(10)의 고정 플랜지 등에 고정될 수 있다.The band 21 on the upper side can be fixed to the slider 50 by welding or the like and the band 22 on the lower side can be fixed to the fixing flange or the like of the casing 10. [
압축튜브(20)는 팽창과 차폐 능력을 증대하기 위하여 다수의 주름을 갖는 것이 바람직하다. 압축튜브(20)는 한번 작동된 후 되돌아 하강되지 않도록 구성될 수 있으며 케이싱(10)의 둘레면에 상하 종방향으로 하강방지용 돌기(라쳇형)가 구성될 수 있다.The compression tube 20 preferably has a plurality of corrugations to enhance its expansion and shielding capabilities. The compression tube 20 may be constructed so as not to fall back after being operated once, and a fall preventing protrusion (ratchet type) may be formed on the peripheral surface of the casing 10 in the vertical direction.
압축 코일스프링(30)은 압축튜브(20)에 압축력을 부여하는 코일형태의 탄성체이며, 도 1의 원호에서 보이는 바와 같이, 단면이 원형이거나 사각형(정사각형, 직사각형) 형태로 제작하여 설치될 수 있다. 특히 단면이 직사각형의 경우에는 좁은 굴착공(1)의 직경 내에서도 코일스프링의 단면적을 크게 높일 수 있어 높은 탄성력을 얻을 수 있는 구조를 만들 수 있다. The compression coil spring 30 is an elastic body in the form of a coil for applying a compressive force to the compression tube 20 and may be formed in a circular shape or a square (square, rectangular) shape in cross section as shown in the arc of FIG. . In particular, when the cross section is rectangular, the cross-sectional area of the coil spring can be greatly increased even within the diameter of the narrow drilling hole 1, and a structure capable of obtaining a high elastic force can be obtained.
압축 코일스프링(30)은 일측이 케이싱(10)에 고정되고 타측이 압축튜브(20)에 연결된다. One end of the compression coil spring 30 is fixed to the casing 10 and the other end is connected to the compression tube 20.
압축 코일스프링(30)과 케이싱(10)의 고정 방법으로는 케이싱(10)의 둘레부에 고정 플랜지(12)를 형성하여 고정 플랜지(12)에 압축 코일스프링(30)을 끼움, 용접 등으로 고정하는 방법이 가능하다. 압축 코일스프링(30)과 압축튜브(20)의 연결 방법으로는 압축 코일스프링(30)을 직접 압축튜브(20)에 묶는 방법, 압축 코일스프링(30)과 압축튜브(20)를 슬라이더(50)(예를 들어 링형)를 통해 연결하는 방법 등이 가능하다.A method of fixing the compression coil spring 30 and the casing 10 is to form the fixing flange 12 at the periphery of the casing 10 and to insert the compression coil spring 30 into the fixing flange 12, It is possible to fix it. The compression coil spring 30 is connected to the compression tube 20 by a method of binding the compression coil spring 30 directly to the compression tube 20 and a method of connecting the compression coil spring 30 and the compression tube 20 to the slider 50 ) (For example, a ring type).
본 발명에서는 슬라이더(50)를 통해 연결되는 것으로 설명하며, 슬라이더(50)는 압축 코일스프링(30)과 압축튜브(20)를 연결하는 기능 이외에 릴리즈수단(40)을 설치하는 공간을 제공하는 기능도 겸하는 점에서 직접 연결방식보다 효과적이다.The slider 50 is provided with a function of providing a space for installing the release means 40 in addition to the function of connecting the compression coil spring 30 and the compression tube 20, It is more effective than the direct connection method.
슬라이더(50)는 케이싱(10)과의 마찰저항을 줄이기 위하여 내주면에 미끄러짐을 유도하는 폴리에틸렌(PE) 필름층이 형성될 수 있다.The slider 50 may be formed of a polyethylene (PE) film layer which induces a slip on the inner circumferential surface in order to reduce the frictional resistance with the casing 10.
압축 코일스프링(30)은 조립과 설치까지는 압축력을 부여하도록 탄성 변형된 상태를 유지하며(도 4참고), 굴착공(1)에 시공된 후 릴리즈수단(40)에 의해 구속이 해제되면 압축력을 부여한다.The compression coil spring 30 maintains the elastically deformed state so as to give a compressive force until assembly and installation (see FIG. 4). When the compression coil spring 30 is applied to the excavation hole 1 and released by the release means 40, .
릴리즈수단(40)은 조립에서부터 굴착공(1)에 대한 삽입까지는 압축 코일스프링(30)이 압축된 상태를 유지하도록 압축 코일스프링(30)을 구속하고 차폐시에는 압축 코일스프링(30)이 펼쳐지면서 압축튜브(20)를 압축하도록 구속을 해제하는 것이다.The release means 40 restrains the compression coil spring 30 so as to maintain the compression coil spring 30 in a compressed state from the assembly to the insertion into the excavation hole 1 and the compression coil spring 30 is unfolded So that the compression tube 20 is compressed.
릴리즈수단(40)은 케이싱(10)에 하나 이상으로 형성된 핀홀(11)에 삽입되어 압축 코일스프링(30)을 구속하는 릴리즈핀(41), 릴리즈핀(41)을 핀홀(11)에서 분리시키는 조작부재로서 당김줄(42)로 구성된다.The releasing means 40 is inserted into the pinhole 11 formed in the casing 10 so as to separate the release pin 41 and the release pin 41 from the pinhole 11 for restraining the compression coil spring 30 And a pulling string 42 as an operating member.
도 5에서 보이는 것처럼, 릴리즈핀(41)은 슬라이더(50)에 전후진[전진은 케이싱(10)의 핀홀(11)에 끼워지는 방향, 후진은 핀홀(11)에서 빠지는 방향] 가능하게 장착되며 당김줄(42)이 연결되는 경사형 안내공(41a)이 구비될 수 있다.5, the release pin 41 is mounted on the slider 50 so as to be movable forward and backward (the direction in which the advance is fitted to the pinhole 11 of the casing 10 and the backward direction is the direction of withdrawal from the pinhole 11) And an inclined guide hole 41a to which the pulling string 42 is connected.
당김줄(42)은 하부가 릴리즈핀(41)의 경사형 안내공(41a)에 연결되며 상부는 지상에서 조작이 가능하도록 지지되고, 따라서, 조작에 의해 당김줄(42)이 지상측으로 당겨지면 경사형 안내공(41a)의 경사 방향에 따라 릴리즈핀(41)이 후진하게 되어 압축 코일스프링(30)의 구속이 해제된다.The lower portion of the pulling string 42 is connected to the inclined guide hole 41a of the release pin 41 and the upper portion of the pulling string 42 is supported so as to be operable on the ground so that the pulling string 42 is pulled toward the ground The release pin 41 is moved backward along the oblique direction of the oblique guide hole 41a to release the restraint of the compression coil spring 30. [
릴리즈핀(41)은 별도의 케이스 안에 설치되어 상기 케이스를 통해 슬라이더(50)에 장착될 수도 있다.The release pin 41 may be installed in a separate case and mounted on the slider 50 through the case.
릴리즈수단(40)은 다양한 실시가 가능하고, 도 11에서처럼, 릴리즈핀(41)은 당김줄(42)에 연결된 가압구(43), 후진방향으로 탄성력을 부여하는 가압스프링(44)의 사이에 개재되어, 압축 코일스프링(30)을 구속하고 당김줄(42)의 당김시 가압구(43)가 빠질 때 가압스프링(44)의 탄성력에 의해 후진하여 압축 코일스프링(30)의 구속을 해제할 수 있다.11, the release pin 41 is inserted between the pushing pin 43 connected to the pulling string 42 and the pushing spring 44 for applying the elastic force in the backward direction So that the compression coil spring 30 is restrained and the compression coil spring 30 is released from the restraint by the elastic force of the pressure spring 44 when the pressure spring 43 is released when the pulling string 42 is pulled .
도면에서 가압구(43)는 당김줄(42)의 당김시 케이스 안에 있는 것으로 도시되었으나, 당김줄(42)의 당김시 상기 케이스 외부로 인출되어 당김줄(42)과 함께 지상으로 회수될 수도 있다.Although the pushing member 43 is shown in the case when the pulling bar 42 is pulled, the pushing member 43 may be pulled out of the case when the pulling bar 42 is pulled, and may be withdrawn to the ground together with the pulling bar 42 .
릴리즈수단(40)은 1개만 적용되는 것도 가능하지만, 압축튜브(20)의 균일한 압축력 등을 위한 2개 이상이 등간격으로 설치되는 것이 바람직하다.Although it is possible that only one release means 40 is applied, it is preferable that two or more of the release means 40 are provided at equal intervals for a uniform compressive force of the compression tube 20 or the like.
릴리즈수단(40)은 릴리즈핀(41)에 의해 압축 코일스프링(30)이 압축된 상태에서 펼쳐지지 않도록 구속하는 안전기능을 수행하지만, 릴리즈핀(41)이 케이싱(10)의 핀홀(11)에 단순히 끼워진 상태이기 때문에 보관이나 운반 중 충격에 의해 핀홀(11)에서 빠질 수 있고, 이렇게 되면 압축튜브(20)가 압축되므로 이를 보완하기 위하여 안전부재(60)가 적용될 수 있다. 즉 안전부재(60)는 압축튜브(20)와 압축 코일스프링(30) 등을 굴착공(1)에 삽입하기 전까지는 설치된 상태이며, 압축튜브(20)와 압축 코일스프링(30) 등을 굴착공(1)에 삽입하기 직전에 분리된다. 물론, 안전부재(60)는 굴착공(1) 외부에서 조작이 가능한 구성인 경우 굴착공(1) 안에 삽입된 후 지상의 조작에 의해 압축 코일스프링(30)에서 제거되는 것도 포함된다.The release means 40 performs a safety function of restraining the compression coil spring 30 from being unfolded in the compressed state by the release pin 41. However, when the release pin 41 is pressed against the pinhole 11 of the casing 10, The safety tube 60 can be applied in order to compensate for the compression of the compression tube 20 because the compression tube 20 can be detached from the pinhole 11 due to impact during storage or transportation. The safety member 60 is installed until the compression tube 20 and the compression coil spring 30 are inserted into the excavation hole 1 and the compression tube 20 and the compression coil spring 30 are excavated Is separated immediately before insertion into the hole (1). Of course, the safety member 60 may be inserted into the drill hole 1 and removed from the compression coil spring 30 by a ground operation if the structure is operable outside the drill hole 1. [
안전부재(60)는 압축튜브(20)의 팽창을 위한 정상적인 릴리즈핀(41)의 동작이 아닌 경우에는 압축 변형된 압축 코일스프링(30)이 압축 변형된 상태를 유지할 수 있도록 하며 예를 들어 양측이 압축 코일스프링(30)을 감싸는 구조의 안전브래킷이 가능하다. 또는 안전부재(60)는 일측이 슬라이더(50)에 회전핀으로 연결되고 타측이 압축 코일스프링(30)의 피치들 사이에 끼워져 압축 코일스프링(30)을 지지하는 것도 가능하다.The safety member 60 allows the compressively deformed compression coil spring 30 to maintain a compressively deformed state when the normal release pin 41 is not operated for the expansion of the compression tube 20, A safety bracket having a structure for covering the compression coil spring 30 is possible. Or the safety member 60 may be connected to the slider 50 at one side by a rotary pin and the other side may be interposed between the pitches of the compression coil spring 30 to support the compression coil spring 30. [
압축 코일스프링(30)과 압축튜브(20)를 고정하는 플랜지, 슬라이더(50)는 압축튜브(20)가 굴착공(1)의 내벽에 닿지 않도록 압축튜브(20)보다 더 큰 외경으로 형성되는 것이 바람직하다.The flange and the slider 50 for fixing the compression coil spring 30 and the compression tube 20 are formed to have a larger outer diameter than the compression tube 20 so that the compression tube 20 does not contact the inner wall of the drill hole 1 .
본 실시예에 의한 상층 오염지하수 유입방지와 구간 막음용 차폐 장치의 작용은 다음과 같다.The operation of the shielding device for preventing the inflow of the upper layer contaminated groundwater according to the present embodiment and the sectional obstruction is as follows.
도 4에서 보이는 것처럼, 압축 코일스프링(30)의 하부에 압축튜브(20)의 상부를 슬라이더(50)를 매개로 하여 연결하고, 압축 코일스프링(30)의 상부를 케이싱(10)에 고정하며, 압축 코일스프링(30)의 하부를 상부로 밀어올려 압축한 후 릴리즈핀(41)을 핀홀(11)에 끼워 압축 코일스프링(30)이 압축된 상태를 유지하도록 한다. 압축 코일스프링(30)은 압축 상태로 변형된 것이기 때문에 원상태로 펼쳐지려는 복원력을 갖고 있지만 릴리즈핀(41)에 의해 구속되어 있다.The upper portion of the compression tube 20 is connected to the lower portion of the compression coil spring 30 via the slider 50 and the upper portion of the compression coil spring 30 is fixed to the casing 10 The compression coil spring 30 is pushed up and compressed to the upper side and then the release pin 41 is inserted into the pin hole 11 to keep the compression coil spring 30 in a compressed state. Since the compression coil spring 30 is deformed in the compressed state, it has a restoring force to be unfolded but is restrained by the release pin 41.
압축튜브(20)의 하부를 케이싱(10)에 고정한다. 이때, 압축튜브(20)의 팽창력을 크게 하기 위하여 압축튜브(20)를 펼친 상태로 고정한다.And the lower portion of the compression tube 20 is fixed to the casing 10. At this time, in order to increase the expansion force of the compression tube 20, the compression tube 20 is fixed in an unfolded state.
압축 코일스프링(30)과 압축튜브(20)의 이웃하는 부분이 연결되어 있고, 서로 먼 쪽인 압축 코일스프링(30)의 상부와 압축튜브(20)의 하부가 각각 케이싱(20)에 고정되고 릴리즈핀(41)이 케이싱(10)의 핀홀(11)에 끼워진 상태이기 때문에 압축튜브(20)는 굴착공(1)의 내경보다 작으므로 굴착공(1)과 간섭을 일으키지 않고 굴착공(1)에 삽입된다.The compression coil spring 30 and the adjacent portion of the compression tube 20 are connected to each other and the upper portion of the compression coil spring 30 and the lower portion of the compression tube 20 which are distant from each other are fixed to the casing 20, Since the pin 41 is fitted in the pinhole 11 of the casing 10, the compression tube 20 is smaller than the inner diameter of the drill hole 1, so that the drill hole 1 can be inserted into the drill hole 1 without interference with the drill hole 1. [ .
압축튜브(20)의 삽입 심도를 감안하여 케이싱(10)을 굴착공(1)에 삽입 설치한 후, 도 5와 같이, 릴리즈수단(40)의 당김줄(42)을 당기면 릴리즈핀(41)이 케이싱(10)의 핀홀(11)에서 이탈되고, 이 순간 압축 코일스프링(30)의 복원력에 의해 압축 코일스프링(30)이 펼쳐지면서 압축튜브(30)를 가압하게 되며, 따라서, 압축튜브(30)가 횡방향으로 팽창되어 둘레부가 굴착공(1)의 내벽면에 밀착된다.The casing 10 is inserted into the excavation hole 1 in consideration of the depth of insertion of the compression tube 20 and then the release pin 41 is pulled by pulling the pulling string 42 of the release means 40, Is released from the pinhole 11 of the casing 10 and the compression coil spring 30 is unfolded by the restoring force of the instantaneous compression coil spring 30 to press the compression tube 30, 30 are expanded in the lateral direction so that the peripheral portion is in close contact with the inner wall surface of the excavation hole 1. [
따라서, 압축튜브(20)를 중심으로 하여 상부와 하부는 서로 격리된 상태로 차폐된다.Therefore, the upper portion and the lower portion are shielded from each other with respect to the compression tube 20 as a center.
본 발명에 의한 차폐장치를 이용하여 지하수의 유입에 의한 오염을 방지할 수 있고, 예를 들어 도 6에서 보이는 것처럼, 압축튜브(20)의 상부에 채움재에 의한 차수층을 형성할 수 있다. 상기 차수층은 초속경 시멘트층(2) - 차수층(3)(시멘트 그라우팅 등)으로 이루어질 수 있다. 도면 중 미설명 부호 3은 양수펌프, 4는 양수관이다.The shielding apparatus according to the present invention can prevent the groundwater from being contaminated by the inflow of the groundwater. For example, as shown in FIG. 6, an aeration tank made of filler material can be formed on the upper portion of the compression tube 20. The aquifer layer may be composed of a very fast cement layer 2 - aquifer 3 (cement grouting or the like). In the drawings, reference numeral 3 denotes a amphibious pump, and 4 denotes a pumping pipe.
또는 도 7에서처럼, 케이싱(10)에 상호 간에 일정 간격을 두고 압축튜브(20)와 압축 코일스프링(30) 조립체(100-1,100-2,100-3)를 2개 이상(도면에는 3개로 도시됨) 설치하여 압축튜브(20)들 사이를 차폐함으로써 구간 차폐도 가능하다. 즉, 부적합 지하수층과 적합 지하수층의 단층 구간을 갖는 지층의 경우 부적합 지하수층을 차폐하여 적합 지하수층의 지하수만을 양수할 수 있다.7, two or more compression tubes (20) and compression coil spring (30) assemblies (100-1, 100-2, 100-3) are provided in the casing (10) So as to shield the spaces between the compression tubes 20 so that the sections can be shielded. That is, in the case of strata having fault sections of the inadequate groundwater layer and the adaptive groundwater layer, only the groundwater of the suitable groundwater layer can be pumped by shielding the inadequate groundwater layer.
