본 발명 오염된 지하수 정화를 위한 강널말뚝식 반응벽체에 관한 것으로, 보다 상세하게는 불량 쓰레기 매립장, 유류 저장시설, 군사시설, 공업단지 등에서 지하수가 오염된 경우 지하수의 흐름을 차단하지 않으면서 지하수를 효율적으로 정화시킬 수 있도록 한 오염된 지하수 정화를 위한 강널말뚝식 반응벽체에 관한 것이다.The present invention relates to a steel pile-type reaction wall for purifying contaminated groundwater, and more particularly, to groundwater without blocking the flow of groundwater when groundwater is contaminated in a landfill, oil storage facility, military facility, industrial complex, etc. The present invention relates to a steel sheet pile reaction wall for purifying contaminated groundwater that can be efficiently purified.

현재, 지표수 대체 수자원으로서 지하수는 매우 중요한 국토자원으로 인식되 고 있다.Currently, groundwater is recognized as a very important land resource as a substitute for surface water.

그러나, 산업활동 과정에서 발생된 유해 폐기물들의 불량매립 또는 오염누출 사고 등에 의해 다양한 오염물질들이 지하로 유입되면서 지하수 오염이 가속화되고 있다.However, groundwater pollution is accelerating as various pollutants flow into the ground due to poor landfill or pollution leakage of hazardous wastes generated during industrial activities.

예컨대, 쓰레기 매립장, 유류 저장시설, 군사시설, 공업단지 등에서는 각종 오염원이 다량 발생되고 있고, 이들 오염원은 곧바로 지하로 침투하여 지하수를 오염시키게 된다.For example, a large amount of various pollutants are generated in landfills, oil storage facilities, military facilities, industrial complexes, etc., and these pollutants immediately penetrate underground and contaminate groundwater.

이에 따라, 더 이상 건강한 수자원으로서의 지하수 활용이 어려워지고 있어 보다 효율적인 정화기술의 확보가 시급히 요청되고 있는 실정이다.As a result, it is difficult to use groundwater as a healthy water resource anymore, and thus, an urgent need for securing more efficient purification technology is required.

이를 해결하기 위하여, 종래에는 지하수내로 파이프를 설치하고 공기를 주입함으로써 탈기시켜 대기로 방출하거나 활성탄 등에 흡착시키는 탈기식 방법을 사용하였으나 이는 막대한 비용과 에너지 소비를 가져와 실용성이 떨어지는 단점이 있었다.In order to solve this problem, conventionally, a degassing method of installing a pipe into the groundwater and injecting air to degassing and adsorbing it into the atmosphere or adsorbing activated carbon is used.

다른 방법으로, 오염원 주위에 불투수성 차수벽을 설치한 후 그 내부를 정화하는 방식이 있으나 이는 차수벽에 형성되는 지점을 굴착한 후 이를 시멘트 및 벤토나이트와 같은 투수성이 낮은 재료를 충진시켜 벽체를 구성하여야 함은 물론 별도의 장비를 사용하여 그 내부를 정화하여야 하므로 정화에 따른 소요시간과 비용이 막대하게 소비되는 단점이 있었다.Alternatively, there is a method of purifying the inside after installing an impervious water barrier around the pollutant, but this is to excavate the point formed in the water barrier and fill it with a low permeability material such as cement and bentonite to form the wall. Of course, there is a disadvantage in that the time and cost required for purification are enormously consumed because the inside of the apparatus must be cleaned using separate equipment.

뿐만 아니라, 설치후 차수벽체의 해체가 곤란하여 정화가 끝난 후에도 불필요하게 지반에 그대로 매립시켜 놓아야 하므로 재활용의 곤란은 물론 또다른 오염 원으로 작용하는 단점이 있었다. In addition, since it is difficult to dismantle the order wall after installation, it is necessary to be embedded in the ground unnecessarily even after the purification is completed, there was a disadvantage of the difficulty of recycling as well as another source of pollution.

본 발명은 상술한 바와 같은 종래 기술이 갖는 제반 문제점을 감안하여 이를 해결하고자 창출한 것으로, 강재로 만든 투과성 이중 반응벽체를 강널말뚝과 동일한 방식으로 지반에 타입하여 곧바로 반응벽체를 형성하고 이를 통해 오염된 지하수를 효율적으로 흡착 정화할 수 있도록 한 오염된 지하수 정화를 위한 강널말뚝식 반응벽체를 제공함에 그 주된 목적이 있다.The present invention was created in view of the above-described problems of the prior art as described above, to form a permeable double reaction wall made of steel on the ground in the same manner as the steel sheet piles to form a reaction wall immediately and contaminated through The main purpose is to provide a steel pile-type reaction wall for the purification of contaminated groundwater that can efficiently adsorb and purify the groundwater.

이때, 상기 하부슈(300)는 별도 제작된 후 용접 등의 접합방식을 통해 상기 이중벽체(100)에 고정됨으로써 일체화될 수도 있고, 아니면 상기 이중벽체(100)를 구성할 때 처음부터 일체로 형성할 수도 있다.At this time, the lower shoe 300 may be integrally formed by being fixed to the double wall 100 through a bonding method such as welding after being manufactured separately, or may be integrally formed from the beginning when configuring the double wall 100. You may.

한편, 상기 이중벽체(100)의 양측면에는 날개형태의 이음브라켓(200)이 일체로 고정된다.On the other hand, on both sides of the double wall 100, the wing-shaped joint bracket 200 is fixed integrally.

상기 이음브라켓(200)은 상기 이중벽체(100)의 상하 길이와 대응되는 길이로 형성되며, 일정크기의 단위체로 제작되는 다수의 이중벽체(100)를 서로 연결하여 원하는 오염원 제거작업을 충분히 수행할 수 있도록 하는 연결부재이다.The joint bracket 200 is formed to have a length corresponding to the upper and lower lengths of the double wall 100, and connects a plurality of double walls 100 made of units of a predetermined size to each other to sufficiently perform a desired pollutant removal operation. It is a connecting member to allow.

상기 이음브라켓(200)은 길이가 짧은 판상의 부재로서 그 일단은 상기 이중벽체(100)의 양측면에 일체로 고정되고, 타단은 그로부터 수평하게 연장된 후 대략 타원형상으로 만곡지게 상기 이중벽체(100)를 향해 다시 절곡(즉, 되돌림 절곡)되어 내부에 체결공간(S)을 갖도록 형성된다.The joint bracket 200 is a plate member having a short length, one end of which is integrally fixed to both sides of the double wall 100, and the other end extends horizontally therefrom, and then the double wall 100 is curved in an approximately elliptical shape. Is bent again (ie, bent back) to have a fastening space (S) therein.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

먼저, 도 2에 도시된 바와 같이, 오염원(C)이 검출되면 상기 오염원(C)으로부터 거리를 두고 오염수가 흘러가는 일정지점의 지면(E)에 이를 차단할 수 있을 정도의 폭으로 이중벽체(100)를 항타하여 파일을 박아넣듯이 박아넣게 된다.First, as shown in FIG. 2, when the pollutant source C is detected, the double wall 100 has a width enough to block the ground E at a predetermined point through which the polluted water flows at a distance from the pollutant source C. ) To drive the file as if it were driving the file.

이때, 최초 항타되어 박힌 이중벽체(100)를 중심으로 그 일측에 형성된 이음브라켓(200)의 체결공간(S)에 다음 항타될 이중벽체의 이음브라켓(200)을 맞추어 끼워 넣은 형태로 일치시킨 다음 이 이중벽체를 항타하여 박아 넣는 형태로 원하는 길이(폭)가 되도록 다수개의 이중벽체(100)를 박아 넣게 되면 본 발명 반응벽체가 완성되게 된다.At this time, match the fitting bracket 200 of the double wall to be hit next to the fastening space (S) of the joint bracket 200 formed on one side with the center of the double wall 100, which is driven and embedded, The reaction wall of the present invention is completed when the plurality of double walls 100 are driven so as to have a desired length (width) in the form of driving the double walls.

이와 같이 반응벽체가 완성되면 오염원(C)으로부터 흘러가던 오염수는 상기 이중벽체(100)에 형성된 투수공(120)을 통과하면서 그 내부에 충진되어 있던 반응물질과 오염원이 반응하여 흡수제거되게 된다.As such, when the reaction wall is completed, the polluted water flowing from the pollutant source C passes through the perforation hole 120 formed in the double wall 100, and the reactant and the pollutant filled therein react to be absorbed and removed. .

이후, 일정시간이 경과된 다음 오염원(C)이 완전히 제거되면(수질 검사를 통해 확인 가능) 상술한 반응벽체를 순차로 뽑아내어 상호간의 결합을 해제시킴으로써 상기 이중벽체(100)를 지면(E)으로부터 용이하게 분리해 낼 수 있으면서 동시에 재사용이 가능하게 된다.Then, if a certain time elapses and then the source (C) is completely removed (can be confirmed by water quality inspection), the double wall 100 is ground (E) by extracting the above-described reaction walls sequentially and releasing the bonds between them. It can be easily separated from and reused at the same time.

이상에서 상세히 설명한 바와 같이, 본 발명은 다수의 이중벽체를 지반으로 항타하는 것만에 의해서도 용이하게 반응벽체를 구성할 수 있어 설치가 쉽고, 시간이 단축되며, 정화후에도 재활용이 가능한 장점을 제공한다.As described in detail above, the present invention provides an advantage that the reaction wall can be easily configured by simply driving a plurality of double walls on the ground, which is easy to install, shortens the time, and can be recycled after purification.
