Description
본 발명은 쓰레기 침출수 발생을 최소화하기 위한 우수 배제 시공방법에 관한 것으로, 특히 쓰레기 매립장 내부의 우수배재시설을 설치. 운영함에 있어서 우수(雨水)가 쓰레기와 접촉하여 발생하는 쓰레기오염수(이하 침출수 라함)의 발생량을 억제하며 매립이 진행됨에 따라 발생되는 침출수의 누출가능성을 최소화 할 수 있도록 하는 개선된 구조의 제방 우수배재부재 및 그 시공방법(Draining Member for Embankment and Method for Installing the Same)에 관한 것이다.The present invention relates to a rainwater rejection construction method for minimizing waste leachate, in particular to install rainwater discharge facility inside the landfill. Improved bank embankment to reduce the amount of waste contaminated water (hereinafter referred to as leachate) generated by rainwater in contact with the waste in operation and to minimize the possibility of leakage of leachate generated as landfill proceeds. The present invention relates to a draining member for embankment and method for installing the same.
일반적으로 계곡부에 설치되는 쓰레기 매립장은, 도 1 및 도 2에 도시되는 바와 같이 매립용량 확보 및 차수시설의 설치를 위하여 바닥면 및 사면을 정리하고 경사면(11)에는 적당한 간격으로 소단부(12)를 시공하게 된다.In general, the landfill is installed in the valley portion, as shown in Figures 1 and 2 arrange the bottom surface and the slope to ensure the landfill capacity and the installation of the water repellent facilities, and the small end portion 12 at an appropriate interval on the inclined surface (11) Will be constructed.
우수가 쓰레기와 접촉하는 것을 방지하고 법면의 경사면(11)을 효과적으로 보호하기 위하여 시공되는 이같은 소단부(12)에는 또한 우수배재측구(13)를 각기 설치하게 되는데, 이와같은 우수배재측구(13)를 중심으로 하여 그 내측에 매립이 진행됨으로 인해 쓰레기로부터 침출수가 발생되는 침출수 발생구역(15)과, 그 외측에 설치되는 우수 배재구역(16)으로 분리하게 되는 것이다.In order to prevent rainwater from coming into contact with waste and to effectively protect the slope 11 of the legal surface, the rainwater discharging side openings 13 are also provided on the small end portions 12, respectively. Since the landfill proceeds to the inner side, the leachate generation area 15 in which leachate is generated from the waste is separated from the rainwater discharge area 16 installed outside.
경사면(11)을 따라 시공된 소단부(12)의 내측, 다시말해 쓰레기 매립구역에서 우수로 인해 침출수가 발생하는 것이며, 이같은 침출수를 효과적으로 집배수 할 수 있도록 침출수 발생구역(15)의 바닥면에 침출수 집배수구(14)를 설치하게 된다.Inside the small end 12 constructed along the inclined surface 11, that is, leachate is generated due to rainwater in the garbage landfill zone, and on the bottom surface of the leachate generating zone 15 to effectively collect and discharge such leachate. The leachate drain 14 is installed.
그리고 나서, 침출수의 누출로 인한 지하수 오염을 방지하기 위하여 도 2에 도시하는 바와 같이 합성수지류 등을 이용한 차수막(20)을 매립지 전체 바닥면에 포설하고, 차수막(20)으로 덮히어진 소단부(12)의 우수배수측구(13)에는 다시 U형측구(21)등을 설치한다. 이같은 U형측구(21)의 저부에는 차수막(20)을 관통하여 설치되는 도수관(22) 및 도수로(23)을 설치하여 주어 쓰레기 매립구역의 바깥쪽에서 발생하는 우수가 쓰레기 매립구역의 내측으로 유입되는 현상을 차단하여 우수 배재구역(16)의 우수가 침출수화 되는 것을 방지하게 된다.Then, in order to prevent groundwater contamination due to leakage of the leachate, as shown in FIG. 2, the membrane 20 using synthetic resins is disposed on the entire bottom surface of the landfill, and the small end portion 12 covered with the membrane 20 is disposed. ), U-shaped side openings 21 and the like are again installed in the storm drainage opening 13. At the bottom of the U-shaped side opening 21, a water pipe 22 and a waterway 23 are installed to penetrate the membrane 20, so that rainwater generated from the outside of the landfill area is introduced into the landfill area. By blocking the phenomenon, rainwater of the rainwater discharge zone 16 is prevented from leaching.
다시말해, 침출수의 대부분은 우수에 기인하는 것으로서 매립지 전체 유역의 우수가 쓰레기와 접촉하는 경우, 이때 발생하는 침출수의 량은 강우유역 면적에 비례하여 증가하게 된다.In other words, most of the leachate is due to rainwater, and if the rainwater in the entire landfill basin comes into contact with the waste, the amount of leachate generated will increase in proportion to the rainfall basin area.
그러므로 이같은 침출수의 발생량을 최소화하기 위하여 쓰레기 매립구역의 바깥쪽에서 발생한 우수를 침출수 발생구역(15)내의 우수와 분리시켜 U형측구(21)등을 통해 매립장의 외부로 신속히 배재시킨 후, 침출수 발생구역(15) 내에서 발생되는 침출수만이 침출수 발생구역(15)의 바닥면에 설치되는 침출수 집배수구(14)를 통해 집수되어 침출수 처리설비(도시생략)로 이송 처리된 다음, 하천으로 방류되도록 하는 것이다.Therefore, in order to minimize the amount of such leachate, the rainwater generated in the outside of the landfill area is separated from the rainwater in the leachate generation area 15, and then immediately discharged to the outside of the landfill through the U-shaped port 21, and then the leachate generation area. Only leachate generated within 15 is collected through the leachate drain 14, which is installed on the bottom of the leachate generating area 15, is transferred to a leachate treatment facility (not shown), and then discharged to the stream. will be.
그러나 U형측구(21)등을 이용하여 우수를 배제하는 종래의 방법에 따르면, 바닥의 차수막(20)을 관통하여 다수의 도수관(22)를 설치하여 우수를 배재하게 되는 것이므로 시공 초기에는 일정기간 동안 도 3과 같은 안정된 설계단면을 유지하게 되는 것이지만, 쓰레기의 매립이 점차 진행됨에 따라 쓰레기의 중량에 의한 지반 침하현상이 서서히 발생되면서 소단부(12)에서 차수막(20)이 하부로 쳐지는등 형상의 변형이 일어나게 되는 것이며, 이로인해 도수관(22) 설치를 위해 천공한 차수막 관통부분(12a)이 파열되어 매립이 진행되면서 매립고가 높아지면 침출수가 파열된 틈새를 거쳐 지하로 유실되는 중대한 문제점이 대두되고 있는 것이다.However, according to the conventional method of removing rainwater by using the U-shaped side openings 21 and the like, a plurality of water pipes 22 are installed to penetrate through the bottom membrane 20 so that rainwater is excluded. While maintaining a stable design section as shown in Figure 3, but as the landfill of the waste is gradually progressed ground subsidence phenomenon caused by the weight of the waste gradually occurs in the small film 12, the water curtain 20 is struck to the bottom, etc. The deformation of the shape will occur, which causes a significant problem that the leachate is lost underground through the ruptured gap when the landfill penetrating portion 12a is ruptured and the landfill is advanced as the landfill proceeds. It is emerging.
뿐만 아니라, 지반침하를 고려하지 아니하는 경우라 할지라도, 쓰레기의 매립이 빠른 속도로 진행되어서 우수 배재구역(16)이 침출수 발생구역화 될 때에는 도 2에서와 같이 매립지역에 있는 다수의 우수 집수용 도수관(22)을 폐쇄하여야 하지만 도수관 설치를 위하여 천공하였던 차수막 관통부분(12a)을 완전히 수밀시공하는 것이 사실상 불가능하며, 결국은 침출수가 파열된 차수막 훼손부위를 통해 누출되는 문제를 해결하지 못한체 방치시키게 됨으로서 환경오염 및 지하수 오염의 주된 원인으로 작용하게 되는 것이었다.In addition, even if the ground subsidence is not taken into consideration, when the landfill of the waste proceeds at a high speed and the stormwater discharge area 16 becomes a leachate generation zone, as shown in FIG. Although the water pipe 22 should be closed, it is virtually impossible to completely watertight the water penetrating portion 12a, which was drilled for the water pipe installation, and inevitably left the leachate unresolved through leaking through the broken water damaged membrane. As a result, it was the main cause of environmental pollution and groundwater pollution.
더욱이 매립된 쓰레기를 전량 제거하기 전에는 침출수 누출부위를 올바로 파악할 수 없어 오염원인의 실태 파악마저도 어렵게 하는등 그 심각성은 이제 사회문제로 까지 확대되고 있는 실정이다.Moreover, the severity of the leachate can not be properly identified until all the landfills are removed, making it even difficult to understand the causes of pollution.
본 발명은, 이와같이 우수 도수로에서 하부 차수막을 관통하여 우수를 배재하는 기존의 방법이 가지고 있는 문제점인 침출수 누출과 이에 따른 지하수 및 하류 지표수 오염을 방지하기 위하여 제안된 것으로서, 우수 배재측구를 매립장 제방측으로 경사지게 설치하고, 제방과 맞닿는 우수 배제측구의 단부에는 제방에 관통되도록 설치되는 제방 우수배재용 관을 매설하여 주어 우수를 외부로 신속히 배출하므로서 기존 다수의 하부 차수막 관통에 따른 침출수 차수기능이 상실되는 현상을 효과적으로 방지하는데 그 주된 목적이 있는 것이다.The present invention has been proposed to prevent leachate leakage and consequent groundwater and downstream surface water contamination, which is a problem of the existing methods for excluding the rainwater through the lower water barrier in the rainwater channel, and the rainwater discharge side is discharged to the landfill embankment side. Installed at an inclined angle, and the end of rainwater drainage side that is in contact with the dike is buried in the rainwater drainage pipe installed to penetrate the dike to discharge the rainwater to the outside quickly to lose the leachate order function due to the penetration of a number of existing lower water barrier film Its main purpose is to effectively prevent it.
본 발명의 또 다른 목적은, 우수배재가 용이한 제방 우수배재부재를 일정한 간격으로 다단 구성하여 두어 매립되는 쓰레기의 증가에 따라 침출수 발생구역을 점진적으로 조절할 수 있도록 하며, 이를 통해 침출수의 발생을 최소화 할 수 있도록 하는 데 있다.Still another object of the present invention is to provide a multi-stage excellent drainage member easily drained at regular intervals to gradually control the leachate generation zone in accordance with the increase of landfill waste, thereby minimizing the generation of leachate It's about making it happen.

이하 본 발명을 첨부한 도면의 실시예에 의거하여 상세히 설명하면 다음과 같다. 도면중 도 4는 본 발명의 시공법에 따라 설치된 제방 측면 배수부재의 설치단면예시도이고, 도 5는 제방을 관통하여 설치되는 배수부재와 경사면을 향해 일정 기울기로 경사지게 설치되는 소단부상의 우수배재측구 연결구조를 구체적으로 도시하고 있는 상세도로서, 본 발명에 따르면, 매립 지반이 조성된 계곡부에 우수배재시설을 설치함에 있어서 우수배재측구(210)를 토사 또는 콘크리트 제방(30)측으로 구배를 조성하여 설치하는 것이 요구된다.Hereinafter, the present invention will be described in detail with reference to embodiments of the accompanying drawings. Figure 4 is an exemplary cross-sectional view of the embankment side drain member installed in accordance with the construction method of the present invention, Figure 5 is an excellent drainage side opening on the small end portion is inclined at a predetermined slope toward the drain member and the inclined surface installed through the embankment As a detailed view showing the connection structure in detail, according to the present invention, in the installation of storm drainage facility in the valley portion in which the buried ground is formed, the storm drainage outlet 210 is formed to the earth or concrete embankment (30) side Installation is required.
이때에 법면상에는 우수 배수시설이 제방(30)측으로 경사가 지도록 동수경사를 감안하여 소단부(12)등을 조성하게 되는 것이며, 차수막(20)이 포설된 소단부(12) 위에는 다시 우수배재측구(210)를 설치하게 되는 것이다. 그리고 우수배재측구(210)가 설치된 소단의 제방측 말단부에는, 토사 또는 콘크리트 제방(30)을 관통하여 시공되는 제방 우수배재용 관(32)을 설치하게 되는 것이다.At this time, on the surface of the rainwater drainage facility to be inclined toward the embankment (30) side in consideration of the hydraulic inclination to form a small end (12), etc. on the small end (12) on which the water curtain film 20 is installed again the rain drainage side opening 210 will be installed. And at the bank end side of the small end where the rainwater discharge side opening 210 is installed, it is to install the storm drainage pipe 32 to be penetrated through the earth or concrete bank (30).
우수배재측구(210)를 통하여 집수된 우수는, 우수배재측구 말단에서 제방(30)을 관통하여 설치되는 제방 우수배재용 관(32)을 통해 원활하게 제방(30)의 바깥쪽으로 흘러내리게 되는 것인데, 이를 위해 제방(30)의 안쪽으로 돌설되는 제방 우수배재용 관(32)의 단부를 도 4에 구체적으로 도시하는 바와같이 소단부(12)를 따라 설치되는 우수배재측구(210)와 소정의 폭만큼 겹쳐지도록 설치한다.The rainwater collected through the rainwater discharge side opening 210 is to flow smoothly through the embankment rainwater discharge pipe 32 installed through the bank 30 at the rainwater discharge side outlet end, and flows outwards out of the bank 30. To this end, as shown in FIG. 4, an end portion of the bank stormwater discharge pipe 32 protruding into the bank of the bank 30 is formed by a rainwater discharge side opening 210 and a predetermined width. Install to overlap.
이때, 제방 우수배재용 관(32)과, 제방(30)에 포설된 차수막(34)과의 수밀성 확보를 위하여 제방 우수배재용 관(32)에 후랜지부를 이루며 용착된 차수편(32a)을 제방부 차수막(34)에 접합하여 주는 것이 바람직하다.At this time, in order to secure the watertightness between the bank excellent drainage pipe 32 and the water-repellent film 34 installed in the bank 30, the order piece 32a welded by forming a flange portion on the bank excellent drainage pipe 32; It is preferable to bond to the order film 34.
차수막(20)으로 복개된 소단부(12)를 따라 길이방향으로 시공되는 상기 우수배재측구(210)는, U형의 측구 이외에도 다른 형태의 우수배재시설로 우수를 집수하는 방법도 가능하다. 예로서, 본 출원인의 선출원인 제 95-37671호 "쓰레기 침출수를 최소화하기 위한 우수 분리용 차단부재 및 그 시공방법"에 구체적으로 소개되고 있는 바와같이 동수경사면을 따라 다단으로 시공되는 소단부(12) 위치에 "ㅗ"형 또는 "Ｌ"형으로 성형되는 통수단면적 확보용 차수편을 각기 설치하여 주어 지반침하등으로 인한 단면적 변화에도 불구하고 안정된 배수구조를 확보할 수 있도록 하는 것이 가능한 것이다.The rainwater discharging side opening 210 which is constructed in the longitudinal direction along the small end portion 12 covered by the water-repellent film 20 may collect a rainwater into a rainwater discharging facility of another type in addition to the U-shaped side opening. For example, as described in detail in Applicant's prior application No. 95-37671, "Separation member for rainwater separation for minimizing waste leachate and its construction method", a small end portion 12 which is constructed in multiple stages along the water inclined surface 12 ) It is possible to secure a stable drainage structure in spite of the change of the cross-sectional area due to ground subsidence, by installing the order pieces for securing the communication area, which are formed in the “ㅗ” type or “L” type, respectively.
이와같이 시공된 매립장의 매립공간에 쓰레기의 매립이 진행되어 매립고가 상승함으로서 쓰레기의 높이가 최하단에 시공된 소단부(12) 위치에 까지 이르게 되면, 소단부에 연결된 우수 배수관(32)을 수밀하게 밀폐하고 나서, 여기에 폐기물을 매립하게 되는 것이다.In this way, when the landfill space of the landfill is constructed and the landfill height rises, the height of the waste reaches the position of the small end portion 12 constructed at the bottom, and the rainwater drainage pipe 32 connected to the small end is hermetically sealed. After that, the landfill will be reclaimed.
이와같은 밀폐작업에는 제방(30)을 관통하고 있는 제방 우수배재용 관(32)의 입구 또는 출구를 일방향 혹은 양방향에서 긴밀하게 밀폐하는 비교적 간단한 작업을 통해 안정된 수밀작업이 이루어 질 수 있게 된다. 즉 매립위치에 시공된 제방 우수배재용 관(32)의 내측에 콘크리트 몰탈 또는 수지물을 체워주어 밀폐하는 경우 충진물의 경화과정에서 미세한 틈새가 형성됨으로서 수밀성이 저하되는 문제점이 발생하게 되는데, 이러한 문제점을 극복하기 위한 방편으로서 콘크리트몰탈 충진 후 차수시트로 입구를 융착하여 폐쇄하거나, 팽창성이 우수한 고탄성의 고무 마개체(35)가 효과적으로 이용될 수 있을 것이다.In such a sealing operation, a stable watertight operation can be achieved through a relatively simple operation of tightly sealing the inlet or the outlet of the stormwater drainage pipe 32 penetrating the dike 30 in one direction or in both directions. That is, when the concrete mortar or resin is filled in the inside of the embankment stormwater drainage pipe 32 installed at the landfill location and sealed, a fine gap is formed during the hardening of the filling, resulting in a problem of deterioration in watertightness. As a means for overcoming, the inlet is fused and closed with the order sheet after filling the concrete mortar, or a highly elastic rubber stopper 35 having excellent expandability may be effectively used.
이같은 마개체(35)는 매립장 내측으로 돌출되는 제방 우수배재용 관(32)의 입구측에 설치되는 것이 바람직하며, 더욱 바람직하기로는 마개체(35)의 단부에 확장된 후렌지부(36)를 구비하여 줌으로서 매립 폐기물의 누름압에 의해 제방 우수배재용 관(32)의 내부로 마개체(35)가 밀려들어가는 현상을 방지하는 것이 좋을 것이다.Such a stopper 35 is preferably installed at the inlet side of the embankment drainage pipe 32 projecting into the buried field, and more preferably has a flange portion 36 extended at the end of the stopper 35. It may be better to prevent the plug 35 from being pushed into the bank of the storm drainage pipe 32 by the pressure of the landfill waste.
이상에서 살펴본 바와 같이 우수가 쓰레기와 접촉함으로 침출수화 되는 것과 우수배재시설의 기능상실을 방지하며, 매립완료 후 침출수가 우수도수로 및 도수관에서 누출되는 것을 방지하고자 우수배재를 제방 측면으로 시공하는 방법은, 단계별 우수배재 소단에서 다수 개소 설치가 불가피하였던 우수도수로가 차수막을 관통함으로서 발생하는 침출수 누출을 방지할 수 있고, 또한 도수로, 도수관등 구조물의 설치비를 크게 절감할 수 있어 침출수 누출로 인한 환경오염 방지와 매립장 설치운영을 경제적으로 수행할 수 있는 효과가 있는 것이다.As described above, the method of constructing rainwater discharge to the bank side to prevent leachate from leaching by contact with garbage and the loss of function of rainwater discharge facility, and to prevent leachate from leaking from storm water channel and water pipe after completion of landfill In addition, it is possible to prevent the leakage of leachate caused by the penetration of the rainwater channel, which has been unavoidable at the stage of storm drainage, and also greatly reduces the installation cost of structures such as waterways and water pipes, thereby preventing environmental pollution due to leachate leakage. It is effective to economically perform the installation and landfill operation.
