관정개발용 외부케이싱의 설치 구조{Install structure of outer casing for developing of underground water well}Install structure of outer casing for developing of underground water well}

본 발명은 지하수 관정을 위한 기초굴착, 직접 굴착 또는 조사 굴착시 최대한 수직으로 굴착하여 지반침하를 방지하여 상층의 오염수와 변질된 지하수의 유동을 최대한 차단하고 보다 안정적으로 시공할 수 있고, 진행속도가 빠르고 시공이 간편한 관정개발용 외부케이싱의 설치 구조에 관한 것이다.The present invention prevents ground subsidence by digging as vertically as possible at the time of foundation excavation, direct excavation or irradiation excavation for groundwater wells to block the flow of contaminated water and altered groundwater at the top, and can be constructed more stably. It is related to the installation structure of the external casing for the development of wells which is fast and easy to construct.

일반적으로 먹는 물, 생활용수, 공업용수, 농어업용수, 온천수의 목적으로 지하수 취수시설을 개발하고 있음은 다 아는 사실이다. In general, it is known that groundwater intake facilities are being developed for the purpose of drinking water, living water, industrial water, agricultural fishery water, and hot spring water.

이러한 지하수 취수시설은 통상 수중 모터펌프를 통하여 지하수 관정 내부의 지하수를 외부로 토출하여 사용하도록 되어 있다.The groundwater intake facility is usually used to discharge the groundwater inside the groundwater wells to the outside through an underwater motor pump.

이와 같은 지하수를 사용하기 위하여 케이싱보다 넓은 에어해머를 사용하여 지표면부터 일정한 깊이로 굴착하여 케이싱을 설치하고, 케이싱 외측으로 밀크 시멘트나 벤토나이트 등을 주입하여 오염된 상층 지하수를 차수하고 있다.In order to use such groundwater, an air hammer wider than the casing is used to excavate the casing to a predetermined depth from the surface of the ground, and to inject milk cement or bentonite to the outside of the casing to order the contaminated upper groundwater.

그런데 에어해머로 기초굴착을 함으로 지층이 들썩거리고 불안정하여 지반침하 현상이나 주변의 오염수와 변질된 지층의 지하수가 유입되게 되는 문제점이 있었다.However, the ground excavation was unstable and unstable due to the foundation drilling with the air hammer, so that the ground subsidence phenomenon or the contaminated water and the groundwater of the altered ground were introduced.

또, 도 1에 도시된 것처럼 종래의 외부케이싱 설치 구조는 외부케이싱을 중앙에 고정시키지 못함으로 인해 외부케이싱이 한쪽으로 기울어 관정 내벽과 케이싱이 한쪽으로 치우치게 되어 정확한 시공을 하기 어려운 문제점도 있었다.In addition, the conventional outer casing installation structure, as shown in Figure 1, because the outer casing is not fixed to the center, the outer casing is inclined to one side, and the inner wall of the well and the casing are biased to one side, there is also a problem that it is difficult to precise construction.

이는 일정한 깊이까지 밀크 시멘트와 벤토나이트를 주입하지 못하게 되어 상부의 오염수와 변질된 지하수가 빠르게 유입되는 통로를 제공하게 되어 주변지층까지 영향을 주게 되는 2차적인 문제점까지 있었다.This prevented the injection of milk cement and bentonite to a certain depth to provide a passage through which the contaminated water and the deteriorated groundwater flowed in quickly, there was a secondary problem affecting the surrounding strata.

또, 외부케이싱의 내부에는 삽입되는 롯드의 위치를 고정시켜주는 중심굴착링을 설치함으로써 직접 굴착 뿐만 아니라 조사공 굴착시에도 수직으로 굴착을 진행시킬 수 있게 하려는 것이다.In addition, by installing a central drilling ring to fix the position of the rod to be inserted into the outer casing to be able to proceed with the vertical drilling at the time of drilling as well as direct drilling.

이처럼 외부케이싱의 기울어짐을 방지하고, 수직으로 굴착함으로 인해 그라우팅 효과를 극대화하여 오염된 상층수와 변질된 지층의 지하수 유입을 원천적으로 차단하고, 오염물질이 지하수 내부로 유입되는 것을 방지하려는 것이다.In this way, to prevent the inclination of the outer casing, and by excavating vertically to maximize the grouting effect to block the inflow of contaminated upper water and groundwater of the deteriorated strata, and to prevent contaminants from entering the groundwater.

아울러, 상부에 캡을 설치하여 굴착시 불순물이 그라우팅공간으로 유입되는 것을 방지하려는 것이다.In addition, by installing a cap on the top to prevent impurities from entering the grouting space during excavation.

이하, 본 발명의 관정개발용 외부케이싱의 설치 구조에 대해 첨부된 도면을 통해 상세히 설명하기로 한다Hereinafter, the installation structure of the outer casing for development of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 관정개발용 외부케이싱의 설치 구조의 구성요소인 흙막이케이싱(10)은 착정기몸체에 부착된 스크류와 에어해머(51)로 기초 굴착을 실시한 후 굴 착된 기초굴착홀(60)의 내주면에 설치된다.The earth retaining casing 10, which is a component of the installation structure of the external casing for the development of the present invention, is subjected to the basic excavation with the screw and the air hammer 51 attached to the body of the fitting, and then the inner circumferential surface of the excavated basic excavation hole 60 Is installed on.

흙막이케이싱(10)은 금속 또는 합성수지재 원통형으로 구성되며, 중앙은 개방된 형태를 갖는다.Soil casing 10 is made of a metal or synthetic resin cylinder, the center has an open shape.

본 발명의 관정개발용 외부케이싱의 설치 구조의 구성요소인 외부케이싱(20)은 본 발명의 주요 기술적 특징 중 하나로, 도면을 통해 알 수 있듯이 흙막이케이싱(10)의 내측 중앙에 설치되며, 외주면에 간격유지부재(21)가 설치되어 있는 것이 특징이다.The outer casing 20, which is a component of the installation structure of the external casing for development of the present invention, is one of the main technical features of the present invention, and as can be seen from the drawing, is installed in the inner center of the earth retaining casing 10, and on the outer circumferential surface thereof. It is characterized in that the gap maintaining member 21 is provided.

간격유지부재(21)는 끝단이 흙막이케이싱(10)및 기초굴착홀 내주면에 밀착되도록 구성되어 있어 외부케이싱(20)이 흙막이케이싱(10)및 기초굴착홀 내부에서 기울어지는 것을 방지함은 물론 중앙을 유지할 수 있도록 하며, 변형되는 것을 방지하는 역할까지 감당하게 된다.The gap retaining member 21 is configured so that the end is in close contact with the earth casing 10 and the inner circumferential surface of the foundation drilling hole, so that the outer casing 20 is prevented from inclining inside the soil blocking casing 10 and the foundation drilling hole, as well as the center. It can keep up with the role to prevent deformation.

이러한 외부케이싱(20)의 간격유지부재(21)는 도시된 것처럼 외부케이싱(20)에 일체로 용접되어 형성될 수도 있으며, 볼트 등의 방법을 통해 외부케이싱(20)의 외주면에 분리가 가능하도록 설치할 수도 있다.The gap maintaining member 21 of the outer casing 20 may be integrally welded to the outer casing 20 as shown in the figure, and may be separated from the outer circumferential surface of the outer casing 20 by a bolt or the like. You can also install.

본 발명의 관정개발용 외부케이싱의 설치 구조의 구성요소인 중심굴착링(30)은 본 발명의 또다른 기술적 특징 중 하나로, 도면을 통해 알 수 있듯이 외부케이싱(20)의 내부 중앙에 설치되며, 중앙에 롯드삽입홀(31)이 형성되어 있어 외부케이싱(20) 내측으로 롯드(50)를 관통시켜 설치할 수 있도록 구성되어 있다.The center drilling ring 30, which is a component of the installation structure of the outer casing for the development of the present invention, is one of the technical features of the present invention, and can be installed in the inner center of the outer casing 20, as can be seen from the drawings. The rod insertion hole 31 is formed in the center and is configured to be installed by penetrating the rod 50 into the outer casing 20.

중심굴착링(30)의 특징 중 하나는 외주면에 다수 개의 날개(32)가 설치되어 있고, 이 날개(32)는 외부케이싱(20)의 내주면에 밀착되도록 구성되어 있으며, 롯드(50)가 외부케이싱(20)의 내부 중앙에 위치할 수 있도록 되어 있는 점이다.One of the characteristics of the central drilling ring 30 is a plurality of wings 32 are provided on the outer peripheral surface, the blade 32 is configured to be in close contact with the inner peripheral surface of the outer casing 20, the rod 50 is the outside The point is to be located in the inner center of the casing (20).

즉, 중심굴착링(30)을 설치하는 이유는 외부케이싱(20)까지 설치가 끝난 후 외부케이싱(20) 내부에 에어해머(51)와 비트(52)가 설치된 롯드(50)를 삽입하여 기초하부홀(70) 굴착을 실시할 때 롯드(50)가 정확한 지점을 향해 하방 이동할 수 있도록 하고, 중심을 유지할 수 있게 하려는 것이다.That is, the reason why the center drilling ring 30 is installed is based on the insertion of the rod 50 in which the air hammer 51 and the bit 52 are installed in the outer casing 20 after the installation is completed to the outer casing 20. When the bottom hole 70 is excavated, the rod 50 is allowed to move downward toward the correct point and to maintain the center.

이처럼 외부케이싱(20)의 외주면에 설치되는 간격유지부재(21)와, 외부케이싱(20)의 내부에 설치되는 중심굴착링(30)에 의하여 직접 굴착 과정 및 기초하부홀(70) 굴착 과정에서 정확한 지점을 굴착할 수 있게 되며, 롯드(50)가 수직으로 이동할 수 있도록 할 수 있게 된다.As such, in the direct excavation process and the foundation lower hole 70 excavation process by the gap maintaining member 21 installed on the outer circumferential surface of the outer casing 20 and the central excavation ring 30 installed inside the outer casing 20. It is possible to excavate the exact point, and to allow the rod 50 to move vertically.

또한, 흙막이케이싱(10) 측을 향해 압박을 가하여 흙막이케이싱(10)이 기울어지거나 휘어지는 것을 방지할 수 있게 된다.In addition, it is possible to prevent the tilting casing 10 is inclined or bent by applying a pressure toward the blocking portion 10 side.

이와 같은 구성에 있어서, 외부케이싱(20)과 흙막이케이싱(10) 사이 공간의 상부에 캡(40)을 설치할 수 있다.In such a configuration, the cap 40 may be installed in the upper portion of the space between the outer casing 20 and the earth retaining casing 10.

캡(40)은 도시된 것처럼 중앙에는 외부케이싱(20)이 관통되기 위한 외부케이싱관통홀(41)이 형성되어 있으며, 하단에는 흙막이케이싱(10)의 상단에 안착될 수 있도록 걸림 턱(43)이 형성되어 있는 형태가 가장 바람직하다.The cap 40 has an outer casing through-hole 41 for penetrating the outer casing 20 at the center thereof, as shown in the figure, and has a locking jaw 43 at the bottom thereof so as to be seated on the top of the earth casing 10. The form in which this is formed is the most preferable.

아울러, 캡(40)을 용이하게 설치하고 이동시킬 수 있도록 하기 위하여 도시된 것처럼 캡(40)의 상부에 손잡이(42)를 설치할 수도 있다.In addition, the handle 42 may be installed on the upper portion of the cap 40 as shown in order to easily install and move the cap 40.

이상과 같이 구성된 본 발명의 관정개발용 외부케이싱의 설치 구조는 기초 굴착 및 기초하부홀(70) 굴착 시 롯드(50)의 위치를 가이드함은 물론 중심을 유지시켜 수직으로 굴착되도록 하는 역할을 하게 됨은 물론, 흙막이케이싱(10)이나 외부케이싱(20)이 기울어지는 것을 방지하고, 흙막이케이싱(10)이 토압에 의하여 구부러지는 것을 방지할 수 있게 된다.The installation structure of the external casing for the development of the present invention configured as described above serves to guide the position of the rod 50 during the excavation of the foundation and the foundation lower hole 70 as well as to maintain the center and to excavate vertically. Of course, it is possible to prevent the earth casing 10 or the outer casing 20 from tilting, and to prevent the earth casing 10 from being bent by earth pressure.

아울러, 상부에 캡(40)을 설치할 경우 굴착시 외부로부터 이물질이 그라우팅공간에 유입되는 것을 방지하여 그라우팅 공간의 확보가 유리하게 되는 것이다.In addition, when the cap 40 is installed on the upper portion, it is advantageous to secure the grouting space by preventing foreign matter from entering the grouting space from the outside during excavation.

상기와 같이 구성된 관정개발용 외부케이싱의 설치 구조는 비단 지하수의 개발에만 사용되는 것은 아니며, 다양한 형태의 홀을 안정적으로 정확하게 시공하고자 할 때에도 적용하여 사용할 수 있다 할 것이다.The installation structure of the external casing for the development of the wells configured as described above is not only used for the development of silk groundwater, but may also be used when it is desired to stably and accurately construct various types of holes.
